Gt-R
DIY Si - 16/8/06 at 05:15 PM

Evening all,
Due to various car related issues I may have to sell the indy in the near-ish future. If I do end up selling her, I'll be looking at building what I think is the lastest version of the MK GT1, now made by spires sports cars. Anyone know much about it/them, as the website is a little sparse. Oh, and I'd be looking at a bird (again)/zx-12r or naybe busa powered jobbie. Also, any one know of any similar alternatives?


muzchap - 16/8/06 at 05:20 PM

Hmm seems to be pretty reasonable pricing

I like the 'GULF' coloured one in the gallery!!! What an amazing paintjob!

OOoh I want one!!!


liam.mccaffrey - 16/8/06 at 05:32 PM

im sure that gulf one belongs to someone on here, i am trying to convince myself gulf is the way to go for my car


zilspeed - 16/8/06 at 05:43 PM

The dark blue one belongs to a fella up here - (hello Keith :-) in fact it's actually an MK. Now running a ZZR1200.

Hope to see it in action tomorrow night.


DIY Si - 16/8/06 at 05:54 PM

Zil, let me/us know how it goes. I like the stlying (?) and would prefer them to go/hande etc like a big shiny fast good handling thing! I to like the gulf colours and the spires looks quite cool in stealth black with red touches.


DEAN C. - 16/8/06 at 06:48 PM

Hi,I was one of the first people to drive the GTR and helped out a little bit swopping the original Audi engine, and road testing when Martin was rushing to get it ready for the Donnington show a couple of years ago.
I was also sat as passenger when it threw a rod on the trackday.
I drove the car at pretty high speeds for about 10 miles on the roads and it was very forgiving ,comfortable and handled very well,quite a bit better than an Indy which I rate as very good if not perfect.
It handled and drove better than a lot of production sportscars I can think of.
If you fancy that style you could do a lot worse,I liked it!:

This one has actually been up and running for a while now. It formerly ran a zetec and he has since converted to the bike engine because that's what wins up here. The ZZR engine hasn't been all sweetness and lught, but I'm told it's running well now. I hope so anyway - will let you know.


DIY Si - 16/8/06 at 08:48 PM

DeanC, did you go in the Mk GT1, or the GT-R from spires, since they look, certainly chassis-wise, to be different cars. Also, I thought the GT1 was chain driven, whilst the GT-R appears to have a sierra diff and a short prop. Could be wrong though.


dilley - 17/8/06 at 06:00 AM

Ive been out in the gtr and I was really impressed, only thing I thought a bit odd is how the peddle box is offset,but this is not a criticism just a different design, spire sports cars have finished and improved the gtr really well, it sticks like sh?t to a blanket, has more room inside and of course engine at rear running a short sierra prop, theres plenty of room for what ever engine you choose, I nearly bought one but really wanted a turbo on my indy and couldnt have both,


I cant remember the chaps name now but he will have a really good deal- alot better than advertised!


wheezy - 19/8/06 at 12:39 PM

I have had my GT-R on the road for 3 months now and with a thousand miles on the clock I can safely say that it is a fantastic car to drive. Even round town it is almost like driving a production car but open it up and tip it in to a corner you get loads of grip.
The pedals are ofset to the left from your driving position but after driving it for a while you dont even notice. There is so much space in the engine compartment that you could fit virtually any engine with a change of mounting positions. I believe that spire sportscars have made a few minor changes to the chassis design around the rear bulkhead and engine bay but the car is still very much the same as Martins initial design.


DIY Si - 19/8/06 at 01:08 PM

Cheers for that wheezy. Do you know of anyone in the midlands with one who'd be up for taking me out for a spin? Also, what's it like as a car to build? When you say the engine bay is huge, would it for example fit a nice big V6 in it? With maybe space for a super charger?!


wheezy - 19/8/06 at 02:08 PM

The original GT-R built by Martin at MK Engineering was fitted with an Audi engine from an Audi 80 I believe. The Westfield XTR 4 uses a turbo charged Audi Quatro engine and has roughly the same amount of space in the engine bay. The only trouble is that you will need a gearbox with a trans axle to fit the engine.
By the time you fit a large engine and a transaxle gearbox you are adding a lot of weight to the car so you may have more BHP but the performance will probably be the same as a bike engine instalation.
If you are looking for a test drive give Paul a ring at Spire Sportscars and he should be able to sort you out.

Dave


DIY Si - 19/8/06 at 03:37 PM

He's already offered a go round Snetterton! Only thing is I'm busy. And busy for the next 5-6 weekends.


wheezy - 19/8/06 at 07:19 PM

I dont know of any other GT-R's in your area. I think there is only about 7 completed cars on the road and out of those 2 or 3 are not road legal (not SVA'd).
I guess you will have to wait a bit longer for a test drive.


DIY Si - 19/8/06 at 11:09 PM

Looks like I may be at Snettertom after all. Any one else going? Or specificaly anyone with a Gt-R/Gt1? Ie Wheezy?


wheezy - 20/8/06 at 09:37 PM

Sorry but due to work commitments I wont be able to go. Getting any time off at the moment is a bit of a problem.


Crazy Jay - 22/8/06 at 03:35 PM

Wat a lovely lookin wee car! I am so tempted by one of these. Would it be much more expensive than an indy? How would the handling compare to, say a LMP or radical? Cheers

GTR side

That paint job makes it imo


DIY Si - 22/8/06 at 03:57 PM

There's a price list here. Looking at <£5k for a rolling chassis if you shop around for some of the bits. That would also include the full body, but not painted. I also want mine to have the nice carbon wing! I think it adds to the racing feel of the car.


Crazy Jay - 22/8/06 at 04:06 PM

Yeah the carbon wing is the business! I think some of those nice lightweight hubs from MNR wud be a must and some image billet 15x10in wheels. Damn it, i'd end up spending thousands


procomp - 24/8/06 at 07:37 AM

Hi did you really mention the mk gt and radical in the same sentence and compare handeling. I would sugest you do some research on the lap times of jon isons car in the 750 rgb. And then look at the radical clubsport's that can be brought for 4.5k and then road registerd so say 6k on the road.

cheers matt


Mike S - 24/8/06 at 09:52 AM

Yea right!

Had a look around, a used Radical club sport will set you back closer to £10k. Can't find anything less than £9k.

Unless you have a source?


Crazy Jay - 24/8/06 at 10:14 AM

Procomp, wasnt suggesting the GTR was as good, just asking "How would the handling compare to, say a LMP or radical?" coz obviously its half the price so wudnt expect it to

Wat are the essential features that make a car with the same engine so much faster? Rigidity? Cheers


Crazy Jay - 24/8/06 at 10:26 AM

Anyone know where I can find these lap times? Cant find 'em on the rgb site?
Also, does John not run a 'blade engine?


Peteff - 24/8/06 at 10:41 AM

Jon has a Blackbird engine in his GT1. He's made some chassis alterations and put a different body on it since his last offroad excursion as well. Can you point us towards the times and also towards some of the £4,500 Radicals as the cheapest I've seen is £16,500 and some more in the region of £30,000 . edit:-
I'm not in the market for one so don't worry if you can't find one, I'd just like to see the difference between the top and the lower price machines.

[Edited on 24/8/06 by Peteff]


procomp - 24/8/06 at 01:18 PM

HI lap times are on the 750 web site under racing . price of radicals well i guess that the guys that buy them do a few repairs and a bit of tlc and then sell them for 8-10k are doing it for no profit then . St have a prosport less engine addmitaly for 8k now.

cheers matt

Again too be fair I'm a "fair weather" racer, some of the guys in RGB are National Champions so again its not really like for like, there are quicker cars than the Radical in RGB too, the Radical suffers in RGB due too having too raise ride height which loses some of its aero aids.

My car was driven around Donnington by A.N. other 2 seconds quicker than me and 2 secs off the front runners pace at the time, come on give us a break, Ive got a straight from bike 3 season old engine, one set of tyres all season, sierra brakes front and rear, only just manage too scrape the weight limit, and a carb'd blackbird engine best part of 40-50bhp down too the front runners with there piggy back ecu's on there blueprinted busa and ZX12 engines, hence I have too look for cheap speed, alter rear end etc........

I had an off over a year ago and its still not completely back together due too funds, its called racing on a budget, well no budget actually,

The GT1, GTr given the funds too develop them, an engine and driver better than me & mine could get up there......

Think what I'm trying too say your not really comparing like with like, chassis development, driver capabilities and engine.

oh one last point, the Radicals doing well in RGb cant be had for £4.5K, there engines might though, and I'll stick my head over the parapet too, what are they doing in RGB ? hardly in the spirit of things too the point the 750club have made noises that they don't like them in there as it puts potential "kit car" racers off thinking of doing RGB in the 1st place.

Can direct you too the rumblings about this if you wish.


Jon Ison - 24/8/06 at 08:06 PM

Here is a snippet, basically the rumor mill as Class A cars been moved into bikesports as if the truth be known there ain't many true class A cars left, there out and out racers not "kits", again ready too be shot down.....



Contentious issue number two, and I really hope that Jonathan and Darcy will still speak to me! When viewed from the outside, the Radicals in particular look out of place in RGB. This is the view of pretty much all of the 750MC committee, motorsport journalists, motorsport spectators and pretty much anyone you speak to who is contemplating racing with RGB. Certainly much of this is down to perception, as the Radical is such a well known and successful race car, but its brand identity is some way off the rest of the RGB grid. This bothers the 750MC enormously, and there is significant recent evidence that shows how a formula (Roadsports) can be damaged when a disparity exists with a high budget front running car.

Before the airways are filled with protests I should stress this is a perception, albeit a powerful and strongly held one. We can talk about Martin’s success at Cadwell in the wet etc till we are blue in the face, but the fact is that Jonathan running away and winning by 20-30 secs at Brands with Marcus Pye watching from the media centre will have more than reinforced these perceptions, and it is this combined with the economic pressure that has led to the current proposal.


DIY Si - 24/8/06 at 08:13 PM

So, for someone on a budget (me) the gt1/gtr is the best bet? Especially given that I won't be racing with it.

I have to agree with you there. If you are looking for a car for the occasional track day that is also fun to drive on the open road and will also turn a few heads and you are on a buget you cant get much better than the GT-R (Iam a bit biased).

And if you take your car to Le Mans most people think you are driving a Radical anyway


procomp - 25/8/06 at 08:52 AM

Hi so there you have it you can have a car that sort of looks like a race car that is suitable for a sunday afternoon drive that will only cost you £-?. But put it on a track day and get left behind by a hole host of other kicars that have cost 4-8k including a genuine radical or even an elise-mx5.

It's almost got the looks but it ain't got the handeling. Just needs the neon lights and the big crome exhaust and you can join the others down the asda carpark on a saturday night.

cheers matt


DIY Si - 25/8/06 at 09:53 AM

Since you seem to know fair bit about racing these type of things, what would make it handle the way you'd expect? Different set up, different chassis altogether or something else? Also, how would you say the Gt-R handles when compared with an Indy? As this is what I currently have and wish to go to something better? And I already know you don't really like the indy.


Crazy Jay - 25/8/06 at 10:24 AM

Procomp hav u driven the GTR?

not so on any trackdays ive been to. In my bec locost with dreadful handling i only get overtaken a few times each day, and its rare that there are cars you cant keep up with. Exceptions are the nutters with busas and cossy turbos, but theres never many of them.

Plus trackdays are about fun, so it wouldnt matter if you got dropped anyway.

You seem to have a chip on your shoulder about mks in general matt, any reason?


ASH3 - 25/8/06 at 07:48 PM

Why is it some people think that by puttin
a kit car on the track it has to beet the rest
surely its the fun of bein out there that counts.
Who is this Procomp anyway sounds like he is on here to anoy us all!


JoelP - 25/8/06 at 08:13 PM

Jon Ison - 25/8/06 at 08:19 PM

Just a couple of points so people know where I'm coming from.........

This "Don't knock MK" thing that crops up ?

I'm afraid I will always stand there corner as without generosity way and beyond the call of duty from Martin, Phil and Bazz there is know way I would ever have ventured onto a race track.

RGB class A ? I cant think of one car in there that's a "kit" that punters can buy, well you can buy them I suppose but there not the "kit" you buy too run on the road but the "race developed" derivative chassis cost 3 times the kit price, brakes, suspension etc...... The big debate at the moment is too scrap class A and just run the fire blade class C as in 750mc's own words.. " class A is full of race cars made road legal" rather than "road cars modded too race" They want too put class A cars into bikesports, wings slicks etc which is where maybe cars like the radical belong anyway ?

Sour grapes, maybe I dunno, you decide but its a bit disheartening sometimes when it rains and you've only one set of tyres and whilst your cooking on your disposable BBQ you can see the lap tops out plugged into cars, only thing I plug in is jump leads......

The GT1 was never a race car, but IMHO a nice looking kit, I just decided too race one with huge help from the people mentioned above.

Knockers please remember, without racers like myself there would be no racing.

Ahhh, now it makes sense....

As far as track days are concerned, who cares if you get overtaken - so long as you're having fun it doesn't matter!

And regarding Jon's comment - I support the shoestring club racer to the bitter end! I race bikes in the Yorkshire hillclimb championship (came 3rd overall last year) but had a massive get-off at the first meeting this year on my TZ250 GP bike, causing too much damage for me to afford to fix. This means that this season has been a wash-out for me....

If you have a class that is meant to be competitive - keep it competitive! Ban slicks, laptops, weather stations (though I have one), Winnebagos etc.

If a class is meant to be cheap (i.e. RGB) keep it cheap!

I think we've gone a bit off-thread here....


DIY Si - 29/8/06 at 12:26 PM

So, apart from procomp, most deem the car, as with most kits, to be perfectly acceptable for general/fast road/odd track day use? Remebering it only costs £6-7k(ish) to be on the road.


wheezy - 29/8/06 at 12:50 PM

There is also a review of the Spire GT-R on the Total kitcar website from a few months ago. LINK
He seems to like it as well.


DIY Si - 7/9/06 at 11:16 PM

Since i'm looking more and more at this, anyone know of a smallish (size wise, not nessecarily cc wise) v8 that might fit? Any other engines that might do nicely? Im thinking audi/vw 1.8T (tuned to 200+bhp), zx 12R, zzr1400, or Duratec (or similar) V6. Suggestions and comments please gent and ladies.

[Edited on 7/9/06 by DIY Si]


DIY Si - 8/9/06 at 11:02 PM

Whilst I'd love to have uch a mental level of power, I have to run all this pass the boss. Also, how much would the engine and box weigh? It might be a fair squeeze in the boot! I also love having a 11k+ rpm limit, so am probably looking at zx12 or if I can find/steal one zzr1400, since a mate of mine is starting work in the industry so parts might have just gotten cheaper!


dilley - 11/4/07 at 08:12 AM

has anyone got any build pics of the gtr???chassis,engine position etc.....
