alternative engine for my kit car project
Discussion
Right basically ive got a project, should be starting this summer. All hush hush atm 
want to reveal it when done 
The kit weighs around 300-350kg without an engine.
The engine i had in mind was a hayabusa running 600hp! After talking to a company i was going to use 600hp was only available from race fuel
but 350hp was using pump fuel - so not bad but that was around £9k of tuning! Money i cant really justify. So my question is which engine should i put in that will have/tuned to atleast 350hp whilst keeping reliability involved.
Budget talking 3k max for engine plus ideally 3k mods max. Or up to 4/5k for an engine with the power there.
Upgrades were going to be a later on this year when i had more funds
Cheers

I don't think you are going to get that from many engines reliably.
How about the Honda Vtec with a Rotrex supercharger? I would imagine that would be about on the money.
Alternatively Omex and RAW are doing supercharged Zetecs at around that power.
Ahh man, im going for a crazyy project! But would be next year if i were to stick in say an rs4 lump or something powerful How about the Honda Vtec with a Rotrex supercharger? I would imagine that would be about on the money.

any other engines you recommend? Having a look it seems there arnt that many "/The company im buying the kit from said their vtec engine did 60 in 3.2secs. Would like to try and beat the bugatti's 2.7
if you want reeaaaaaallly big power then the GM LS7 lump is good.
I know of a company who used one with twin turbos @ 2200bhp in a road legal car
engine was built by NRE in the States, but it cost a few bob!

got to start somewhere though!

From your posts, it looks as if you originally wanted a lightweight power plant, but now you don't mind how heavy it is. From bike engine to supra turbo; will your design accommodate any size engine?
Yes the company has fitted a 3.2! Their design means practically any size can be put in, they will just adjust the rear bumpers/mounts. They build the kit to the customers requirements slomax said:

Oh how id love to! 7 litre is far too big though haha. And insurance would deny me straight away!I know of a company who used one with twin turbos @ 2200bhp in a road legal car

Although the power to weight ratio would be about 4000hp/tonne! I dont think the wheels would grip haha

sorry, but big power costs, which everway you do it, and once you have big power you need a suitable transmission system to use it, which is the bit most people forget!
oh don't i know it LOL, can use rs4 box with engine good for more than the standard 360hp, just need to remove the 4 wheel drive partMax_Torque said:

Evo is transverse lump though so no idea which box you'd need for inline - I'm assuming it is FE-RWD. It may also need dry-sumping too, certainly does for high lateral g applications although inline mounting may reduce risk.
Impreza lump and box is suitable though and you can get RWD kits for them.

Cheers for the replies, some good ens. How important is a dry sump? As you can tell i know naff all
It really depends on the engine and the car you'll be fitting it to and where that will be driven.The 1000cc and less bike engines seem to cope ok without a DS. Some will baffle the sump to avoid oil surge, but others have raced them on slick shod sevens without problem. On the bigger bike engines Bird, Busa, ZZR14 they are essential - and a £1500-£2k mod.
Car engines really depend on the engine. Evo's running wings and slicks for example really do need a DS to avoid surge / starvation problems. On normal tyres without wings you should be fine with most engines using either standard or baffled sump or an accusump system. Add in wings and slicks and you start to sustain g loadings which will see big end bearings running without oil for 'long' periods.
The easiest way to check is to look at the engine specific forums.

yeh when i spoke to bigcc they said they recommend a DS on a busa. I was thinking maybe the celica engine twin turbo. They run about 350hp and can be tuneable from there. I think ill get a DS just in case. No harm done The 1000cc and less bike engines seem to cope ok without a DS.

Any idea how high bhp? Im looking for about 500hp
Some claim around 600bhp on stock pistons on the b204 engine. One chap has a 170k mile engine at 400+This is the internet though...
The oem trionic ecu is mappable and uses clever ionic knock sensing. I am thinking more along the lines that this is a cheap way to make the kind of power you want.
That is about the limit of what I know about them, mainly picked up from a mate running one in his Haynes roadster.
