majorly off boost?? I'm not really expecting much lag with a lightly twin turbo'd v6 - in the light car should hopefully just feel like a
strong engine. Will be interesting to see anyway - it'll be NA with around 200bhp initially while i get comfy with the megasquirt.

I think you'll be ok with your car if I'm honest Liam.
I've driven a twin turbo XR4x4, with the pair of diddy turbos on it and that drove very well I will admit, but there was a lot of plumbing!
Don't underestimate the difficulty of "keeping it singing" though! Believe me I don't hang about when driving "in
earnest" but most road car gearing is very wide for a turbo power band!
The best turbo car I have ever been in was an Escort Cossie shell fitted with an "ex granada" Cossie V6 and full ford motorsport 4wd
transmission. 3.7 litre stroker steel billet crank, forged pistons, billet rods, flowed heads, twin turbocharged, huge intercooler very nicely made
and superb design of inlet plumbing including made from scratch ally inlet manifolds and stainless tubular exhaust manifolds before the turbos.
Was revving to 9,000 rpm or just over and made just a little over 700hp, and about that figure in lbft of torque.
Was an interesting car when used on the road!
Broke £20,000 gearboxes with alarming regularity though, hence why it has been dismantled!

i would love to go Zetec bottom end as i said at the begining my friend is rebuilding his rs Turbo & he is going that way but it costs. i think
that will be a later project...but the idea is there...
i also do not mean a silly 206 gti is going to beat a 2ltr zetec kit car. but a classic Super 7 had a 1.6 single cam engine with little torque also
its 30 years old. this technology has been superseeded.
superceded maybe but it will still thrash a 206 gti around a track!

BIKE ENGINED CAR = BEC
As for the ZVH its a nice idea but as a bitsa engine its a bad idea challange or not.

Q- As for the ZVH its a nice idea but as a bitsa engine its a bad idea challange or not.
A- WHY???
its a strong engine? its know to produce 200bhp cheaply & easily.
its a standard engine so the only alterations would be mods i want to do rather than mods that would be needed.
the pipe work is straight forward couple of new pipes larger bonnet....& done.. well thats the plan!

I was looking at going down the route of putting an car engine into.... what that thing called.. a car
BUT THEN
I found out about this amazing thing where you put a Bike engine into a car and it was love
Im still not a total BEC head but I am getting there you should look into it
0-60 in under 4 sec

I realy don't want to wee on your chips but reading this thread from start to here I get the distinct feeling that you have gone to an open day
and come away dreaming.
I may be wrong.
Your best course of action would be to listen to the people on this forum.
There are a lot of very experienced builders on here ( and I don't necessarily include myself in this catagory). Listen to what you are being
told.
Do lots of research first. Then you stand more chance of getting a useable car on the road/track rather than another pile of bits on e-bay.
I honestly do not think youy have any idea of the performance of these cars even with a lowly 1600 Kent in them.
It's all about power to weight ratios.
Thats what gives you the blistering acceleration. Top speed is HP related.
and there are published formulas for working out top speeds with drag coefficients and horse power. Like I say do the research.
Don't assume that just because an engine has forced induction that it is going to outperform a similar car that is na. It aint always so.
Experience is what you get when you don't get what you want!!!

Just recently, I've been hooning round in Roland's book Locost with bog standard crossflow (86 bhp if you're lucky). It is SO MUCH
FUN!
I'd like to see a 206 keep up with that!
Mine uses a 1700 crossflow (about 120 bhp) It's mad!
These are both 30 year old engines and can still outperform all but the supercar brigade, especially on the twisties.
CVH engines can be tuned for more power than crossflows due to their larger standard valves and better combustion chamber design. I'd say build
the turbo lump and have a larf!!

so i want to build a Rs turbo Kit car!!!!!
So build one, don't ask for approval or opinions you don't really want, get forward and then tell us about it after. If you've built
it you'll like it and you don't need to justify yourself or your motives to anybody else. Sylva Mojo would be your easiest option I think
as it can use the Escort/Fiesta in the rear with it's front wheel drive box, get your hand in your pocket, get the spanners out and stop
dreaming.

yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I say go for it, be different, that is the beauty of the seven, everyone likes something different but the principal is the same. You like messing
with cars. I have driven a turbo'd seven for 6 years now and it still scares me. I like the torque you get from a turbo car whether it be petrol
or diesel, as Liam said you get the best of both worlds docile off boost and not so docile on boost. Turbo lag isn't nearly as bad these days
due to better turbo and tuning technology and in my opinion it is no different to most modern day 16v engines which have very little power or torque
low down in the rev range and then come on cam at about 4000 rpm. I drive a Clio 182 as an everyday car and whilst it is good fun it is tiresome
trying to get the best from it due to relatively small power band high up in the rev range and the constant gear changing required to keep it all
singing. I have no doubt that bike engines are fun and make all the right noises but an r1 engine can't make 200lb/ft torque at 2500 rpm can
it now (well not without a turbo anyway). Snails and front diffs rule.

Hi
Theres a chap on the westy forum who's just upgraded his n/a cvh to an rs turbo have a look at

if you want the bec experience put your car in second gear and drive along a dual carriageway at 50mph and see how long you can stand it for 
cue abuse about wheezy v8,s and boat anchors
