Im building a kit car and want to use a bike engine to power it. It will weigh under 400kg and was wondering what engine options i have. Id prefer something around 120bhp or more but needs to be reliable dont want to have to rebuild it every 5 mins. I'll have up to about £7-800 to spend on one. I know i could get a blade, R1 etc just wondering what other engines there are out there. Would like to get hold of a damaged bike and strip it so i dont have to keep searching for parts bit by bit.

Cheers

suzki haybusa mate , 1300 cc

plenty of companies using them for kit cars so good for conversion parts , linkages ect

170 bhp in standard unfettled trim

u could detune it and the upp the power ask ur confidence grows ,

+ turbo kits availabe from the likes of big cc and holeshot

350 bhp sound nice to u ?/

deffo the best option mate

CraigJ

might be the best option but at about £2500 for an engine its a bit steep.

Hoping to be building one of these. Its an Onyx Mongoose. There prototype was fitted with a 1400 k series rover unit with 100bhp and about 450kg. Hopefully with about 120+bhp and less than 400kg it will be a good match for a busa powered car.

r1 engine and box...about a 2002 fuel injected model would be nice,150bhp and should be fairly reliable.

CraigJ

I thought the fuel injected model was about 170 and the carbed one 150. could be wrong like.

better getting a engine with a big clutch have been in a few cars with bike engines and owners always say they wish they went for a older engine with bigger clutch

...no mate the later ones have ram air to give the 180bhp...the early ones still 150bhp

"better getting a engine with a big clutch have been in a few cars with bike engines and owners always say they wish they went for a older engine with bigger clutch Confus"




been thinking this already but i dont know a great deal about bikes. Just want to know what options ive got. The engine does'nt have to be new at all it just needs to have a decent amount of power but not weigh too much. over 100bhp would be ok because of the weight id be saving.

Yamaha FJ 1200 engine? or, if you want somthing really mental, how about a nice suzuki TL 1000S engine? 1000cc Twin, light as fuck, 120BHP easy and a great big torque spike , and the clutch will be stronger as well I would Imagine would sound mint as well

We've picked up a Suzuki GSXR1000 engined Smart roadster in the UK last year, I drove it back home from Calais and we've rebuild it now with LOADS of improvements to make it more driveable and it's going to be used as a daily driver now by some Greek fella!

a 1000 4 pot will have enough power, the smart weighs a fair bit more and was properly fast and entertaining!

i had a 337 bhp r1 turbo it scared the crap out of me but it would be awsome in a lite car big cc,s new busa is near 780 bhp

Busa engines (like you say ) will fetch a premium.

What about kawasaki zx12r or Honda blackbird engines? Maybe they are a cheaper option (although I haven't looked) Or maybe even a ZZR1100 engine, they are prob cheap'ish.

just had a look while writing this..

what about a sneaky offer on this?

What about the Yamaha Thunderace engine ?
Runs on carbs with no ram air to worry about, revs well and makes 120 bhp rear wheel horsepower on a bike. 1002cc twin cam 20 valve with the exup valve to give more low end torque. A billet clutch basket would be a good idea though as they can break the stock cast ones causing trouble.
My FZR1000 used a stock thunderace crank and rods with billet clutch basket and made a very relible 209 rwhp at 10 psi.

ZX12 or Busa engines are made for the weight of a big bike and IMO would suit a small kit car and they are modern. You pay a premium on a busa engine for a good reason!! They are great! Bullet proof and well tunable, plus loads of people have already tuned them/turbo'd them so you've got something to go on!! (just type in turbo busa on google, you'll be up all night watching vids!!)

ZZR1100 is a stonking engine but its getting a bit wrinkly now! As for the bird engine, it is reliable as you like, but I've not seen many highly tuned ones. Don't know why??

Carbed R1s were 140hp
