if you only want moderate power 250 ish then just put a decomp plate in it and bolt it all back together

hey guys ive bought a zetec engine and was wondering wat parts i need to buy? wat wiring and ecu do i need? inlet, turbo manifold etc???


thanks

depends upon the kind of power you want and the kind of budget you have

adduk

are you using the st170 head aswell?,anyone know if they any good for around 300bhp. i thought the block is the same as a zetec but with different internals

Rick

st170 head will do 300, yea.

how much would a st170 head cost me do we think?

crazycage

about £250 for a head and £250 for the valve springs

hello guys as ive said ive bought a complete st170 bottom end. and ive had an offer of a normal black top zetec head. will these two fit together ok? i was just wondering if i would need to change any of the spec of the head to run a t3 turbo. ive got a inlet manifold off a rover 620 ti which i think fits and will be ok.

thanks

ive never built a engine before and so came on here hoping to get some help. not got much so far

Turbocabbie

If you have never built and engine before a turbo'd ST170 is a big step for a first build

With regards to ECU I would find a tuner you trust to map your car and take the advise they have to offer, OMEX, Pectel, Webber, Megasquirt would all be capable of fuelling your car

I would personally change the pistons and rods so that they were not a worry, I would rather know something is strong enough than think or hope that it is

I would not personally take the route of the rover inlet im yet to be convinced of its attributes

You will also have to make mounts for and consider your gearbox options

The reality is if you have no idea of what you're doing you are not going to get all the answers from the internet/forums on how to build a high performance engine and it be successful.

Very true...... 50% of people talking shit, 30% of people repeating shit they've been told, 10% of genuinely helpful people but that dont have all the answers, 9% of people that think they have all the answers, and only 1% of people that actually know what you want to know! LMAO

But generally after enough thrashing about between members the right information will come out!
