The race engine I mentioned was only running on dellorto 40's which are much cheaper than tb's for the cost concious (locost!!) of us out
there

Ok guys, with tuning bits and pieces the XE is obviously a potent engine. However with tuning bits and pieces the Mazda engines can make over 300bhp.
Check out the Flyin' Miata website - but that's taking a daft point and making it even sillier.
It's not what we were asked.
quote:
What's the best engine to look for if i'm looking to spend about £1200 on the engine (inc ECU&ancillaries etc) and gearbox?
Therefore I stand by my original remarks. Cheaper to get the necessary bits and pieces to fit the Mazda engine and get it on the road than the
Vauxhall engine.
The tuning potential is another matter and another cost.

ok then, on a like for like basis:
donor car/engine £400
steel sump from an 8v engine to cut/shut <£50
adapter bellhousing approx £150
pair weber/dellorto 40's <£200
dizzy from an 8v 1.6 mk2 cavalier <£50
inlet manifold <£150
that lot comes to £1000 which is still within his budget and should make in the region of 175bhp.
The only other thing I can think of specific to the engine is the exhaust manifold - you could cut and shut a tubular astra/cavalier one to fit or get
one made from the likes of mk/mnr etc but he has £200 left in his budget towards this. Depends how much you are willing/can do yourself as to how
locost it is!
Ned.
oh, nearly forgot, you can use a ford (xr4 i think copes with the torque) clutchplate in the vauxhall clutch housing.

Ok Ned.....

and earlier I said....
quote:
I paid £600 for an engine with all ancilliaries, 5 speed gearbox, ECU, exhaust manifold etc... No extras - my car runs on the Mazda ECU/fuel
injection
.......QED.
Ps; You didn't include a gearbox in your costing and my engine came with one

I am not arguing the XE is as cheap as an mx5 lump, just that it could be done within the budget he has set.
A standard type9 gearbox will fit the adapter bellhousing with the ford clutch - most people have one from their donor sierra

Here's my actual costs, tho I am not sure until I have typed these what they will tot up to!
Engine £200 tested in donor car
Gearbox £25 (one of 3 bought for £75 total)
Bellhousing £140
Throttle body kit incl MBE 956E ecu etc - £650
Caterham HPC sump £75
Exhaust manifold - well, tricky as it can be done cheap, but mine will be £300 by the time I have made it. Could easily be done for £100 though in
mild steel instead of stainless.
Total = £1165

The 1.6 MX5 lump vs a 20XE is apples and oranges though. The stock Mazda unit will undoubtedly provide a nice tractable and probably very economic
unit at a (very) good price, but
1)They are nowhere near as commonly available as 20XE's
2) The 20XE delivers significantly more power and torque.
You can get 300bhp from the Mazda unit...but you have to turbo it to do so and spend a fortune in the process. Iif you need that kind of power there
is always the C20LET which is turbo'd from the factory and can probably produce that kind of power more cheaply. Finding a gearbox that can
take the torque might be a challenge though...

You're all wrong!! What you really, really want is a nice Mazda 13B rotary with a turbo. Over 200bhp stock, designed for RWD and a noise to make
the hackles rise on the back of your neck.
OK, OK you're not all wrong - that bit was a joke. It's all just horses for courses - I'm bound to stick up for the 4AGE because
that's what I have.
4AGE from breaker 100 quid
T-50 gearbox 150 quid
Exhaust manifold & system 280 quid
ECU free with engine
Loom home-made
Lowered plenum home-made
Shortened sump home-made
Total 530 quid, probably only 130-140 bhp but it sounds fantastic, revs like hell and goes like a rocket.
If I was starting again tomorrow I'd strongly consider a 2 litre Ecotec - very cheap, modern engine, very few mods needed to get decent power,
no probs with porous heads, RWD conversions readily available.
Cheers,
Eddy

Why has no one suggested the Rover V-8? lots around to choose from, lots of bolt on goodies, some mods required to the engine bay to fit it but it
weighs less than a lot of iron block and head 4s. Sounds absolutely brilliant and bags of torque, probablly don't even need a gearbox!

They're not particularly cheap if you want a powerful one but they are utterly fantastic ime.
