ok guys im just starting to sorce new bits for an engine rebulid and need some advice, im going to aim for aroung 400bhp or just over and need to know a spec to aim for i.e. turbo choice, injector size, how far i need to go on the head(big valves ect). also inlet and exhaust manafolds do i go for custom ones. all help wecome.

 

gt in touch with si tech or M4D YETI.

 

check out lukes ( m4d yeti) thread in projects for an idea of what you are gonna need and the cost, dont forget ur gonna need a gearbox and driveshafts that can handle that power, brakes etc, hope you got deep pockets

gearbox, im gonna use a st170 box 6speed with a quaif(sp?) diff. im already running 283mm discs 4pot calipers and discs on the rear.

 

cool the big expense with the st170 gearbox will be the new flywheel and clutch which is needed plus custom made driveshafts, pm luke and he will tell u what u need and what sort of prices ur looking at

 

My ears were burning lol...


Gearbox wise you will need to go MTX to handle that power. You have stated what box your intending to go for and its what I have gone for.

Before you chose anything though you need to decide what the car is used for.

If its a track/racer a road/track car or just a road car.
Bearing in mind to handle the power well you will need to sacrifice some of the refinements you currently may have.

 

Are you sure you want 400bhp? It's very easy to come on the internet and get recommendations for "yeah mate you want 400!!!" but in reality, a genuine 400bhp is unuseable on a road car.

 

ok as for the choice of car its going to be abit of everything track and road

 

For track and road then its slightly different really as realisticly you only want genuine 300 hp MAX!

The mods you need to handle more will make the car drive awful on the road.

 

like what?

 

Surely you should be giving Ian Howell at Area Six a call?

The man has forgotten more about big power zetecs than most will ever know! Very trustworthy and no messing type of guy!

I have used him for over 10 years.

 

Totally depends on how its mapped and delivered! ECU boost control is the way forward. Yep from standstill its useless but map it in progressively and I dont see the problem. As long as you have big arms for the torque steer.

 

Have you driven one?

 

Oh you know, one or two! LOL!

 

I didn't know if your engine had ended up in a car yet? I don't really follow it.

 

I can confirm that the six speed box can take the power. My has been running for 18months now without a single problem. It is also fitted with a LSD.
