250-300bhp reliable engine choices
Ive been sitting here all night trawling thru posts trying to decide what engine will to produce this power. Getting tired and have made little
headway..
Can anyone tell me the best way of making around 250-300bhp in an MK indy r RELIABLY? My initial thought was a supercharge a duratec or zetec or
something but im not sure anymore. What about cosworth engine?
I would also like a setup thats installed commonly so if I have any problems mid build I can turn to locostbuilders for advice from all you guys so
try to keep it simple. 
What setup is best to achieve this easiest? My budget is around £12-15k but the lower the better obviously.
Thanks

12-15K for the engine alone?

I've got an option 6 kit zetec in my car, it's only recently completed but so far so good. The top zetec (option 7) kit should get you,
just, into the 250+ range. The duratec option will push on towards 300.
Give Paul a call, he'll advise options and prices.

I would be looking at the SAAB, Nissan, Opel/Vauxhall, VW/Audi and Volvo range of turbo charged 4 cylinder motors. Any of those should comfortably
and very reliably do what you want with minimal mods.

Cheapest way has to be the Saab 93, you can buy a complete car for a lot less than a grand & it needs (I believe) just bigger injectors & some
turbo mods, 300BHP with no internal engine mods has to be the way to go. You then just need to pickup a suitable gearbox & prop, I believe the
Omega 3.0 MV6 will fit.
Alternatively bolt a Rotrex supercharger to a 'Busa or ZZR1400 & you'll get around 250 - 300bhp reliably providing the engine is
properly installed & won't suffer oil surge
Adding a turbo to a Zetec or Duratec is going to require a lot of (very expensive) internal mods if you want it to be reliable
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

I'm aiming for 350 on a 2.0 zetec.
Intended mods are 8.0 comp ratio forged pistons and h beam rods, obviously a turbo as well.

For reliability a Honda S2000 with some very light tuning would/could be your best choice, the closer the engine is to OEM standard the more reliable
it will be and the S2000 is 230bhp (I think) already.
isn't there an entire S2000,in the for sale section for £4.5k? You could probably break the car and sell what's left after taking the
engine to get a good chunk of that back.

VW audi group 1.8T engine (BAM engine code)... As fitted to the TT, Seat leon cupra R (2003 ish era)...
225hp as standard... remappable to 290 or so... can achieve 350 with a hybred turbo and new injectors...
Pretty heavy and tall engines but very well put together.

S2000 on throttle bodies = 261bhp linky
But that lump is a big un and I doubt it will fit in an MK - so if you have a total budget of £12k -£15k then a Westy is probably of range (might just
do it for £15k if you are very lucky).
DaveB666 has a Nissan turbo in his Locost - see this thread so that means it
should also fit an MK.

S2000 (F20C) is nearly there and as a bonus you get one of the sweetest shifting 6 speed boxes there is, you wont get that with a ford type 9 etc.
To get a Ford Duartec/Zetec etc to this power normally aspirated you are talking silly money and unknown reliability and you'll still have a 25
year old gear box.
I spent a lot of money on booze, birds and fast cars. The rest I just squandered.

I think the S2000 is becoming more appealing! Ill check out the forsale list and see if I could get a good donor. Ill also have a word with the boys
at MK and see what they reccommend.
That is insane power kingster!! Looks very nice 
wyllie does addijg throttle bodies make it too large for fit in an MK?

yes it will cost a lot to get 250+ from a duratec but i don't agree with unknown reliability, plenty of cars are running them with no problems.
also if your spending that much money on the engine you may as well spend a bit more on a decent box. caterham 6 speed is meant to be good or even
better go sequential.
personally i much prefer NA in a lightweight car(infact for me any car) but if going FI i would prefer a supercharger.

Yes, there's a few really nice S2000's that have been IVA'd this year on the WSCC forum - mine's a measly 168bhp Zetec, but
will do me for now

What I mean is; I have seen plenty of F20C engines with 100k plus on them with no problems. If going down the tuned Duratec/Zetec route it's
unknown (to me at least) how long they are expected to last in that state of tune, I'm not saying they won't.
I think the budget stated is for the whole car not just the engine.

How about a nice Lycoming?
Light, powerful, and reliable down to the last nut & bolt.
I bet that would fly.

I too prefer N/A in a lightweight car but I now prefer a turbo in my road car, either petrol or diesel, currently have both on the drive.
I have owned a supercharged car and at the time I thought it was pretty good compared to turbo's of old. But compared to a modern turbo it was
totally pants, would not want another.
Drove a supercharged Seven back in the early 90's. It certainly had adequate of power from its otherwise standard XR3i engine but it did not
appear to be very exciting in the way that my slightly less powerful N/A x-flow was.
The worst turbo car I have ever driven was a 1982 turbo technics XR3i. It was sold officially by Ford at the time by a small number of dealers before
the release of the RS turbo. Power from the engine was pretty sensational but turbo lag was horrendous as was torque steer. The steering issue was
simply because the chassis was standard as were the brakes and tyres, totally inadequate for the performance. Should never have been sold.
It put me off turbo's until 1996 when I bought a Golf Tdi.

I think im going to go S2000 if it has forged internals and can take the power upgrade at some stage in the future then that is perfect for me. Plus
if I change the throttle bodies on it and get about 250 thats sweet as a nut... For now..
