Alright all

Right I am building a rear engined car, and I was going to use a Turbo/SC 2.0l 16v(not YB Cossie) aiming for around 400bhp. However I have been offered a 3.5 Rover V8 for not a lot and it got me thinking. Basically as it is lightweight(6-700kg) will be mid engined using a transaxle to rear wheels, would I be better with a relatively smooth V8 instead of the 2.0l turbo(not so much SC).

So what I was wondering is how easily these can make 400+bhp(more would be fine as long as it's smooth and not major boost spike turbo type power or spin spin spin ) .

My thoughts were a single turbo of maybe GT35/GT40 size running lowish boost with external gate, as these are cheap as hell from US compared to the Rotrex SC I have used in the past that are amazing for FWD due to linear power, but I think with RWD I will get away with some torque spike.

So really just want peoples thoughts on how they would do it......

the rover will make 400 horse but with lots of cash and work - be interesting , ive got a rover in the back of my other car witha transaxle ( project B) so get it done then i can see what its like !!!

you need a lot of work to the heads to get it breathing well enough on the exhaust side to work well with the turbo.

its going to cost you a good few grand, buts its very doable and ultimately going to be far nicer delivery than a 400bhp 2 litre 4 pot.

So is the work mainly needed to the head?(obviously I know it will need low comp forged pistons etc).

And when you say work to the exhaust side just port flowing or are we talking bigger valves?

Is there a better V8 to use?

Yep saw all that Mark, however the engine seema to be an "I don't know" spec so I'd probably take it apart anyway, the turbo kit is a bit..........cobbled and the janspeed is for twin turbo lol.

However cheers again

IMHO use a ford 302ci Windsor V8, easy to do, cheap to do, east to get info too.

Use the rover V8 3.5 as a door stop and stick a 350 CHEVY engine in there because :-

Smaller in size
bigger cc 5.7litre
and £3000 will get you a brand new 420bhp & 460lbsft at 4500rpm engine

Follow the link for more info!!!!

Holy shit HOW CHEAP????

Yank V8 it is, just need to do some measuring now.......

says it all really. the only thing good about a rover is light weight. i had a griff500 with "340bhp and 320lbsft" the rollers said 285bhp however and that is a tuned rover v8 5 litre. the rover heads are crap and you cant get decent inlet manifolds with equal flow. sbc 383cu ci al the way - you can even get alloy blocks now

Next thing is what transaxle to use, I had looked at both the Renault UN and the Audi 100...... Doubt they will handle a V8 though.

Any ideas?

Agree though for the money, small block, alot cheaper for big power,
alot heaver though, even an ally blocked one,

Barry_GTi

Anyone any ideas on transaxles then???
