I have built a 2.0 zetec turbo and put it in my mk4 1.3 bonus, what would I need to make around 250hp? It has a decomp plate, fiesta rs turbo inlet manifold and ofac ecu, escort rs turbo exhaust manifold and t3 turbo, thanks lee

 

virtually nothing lol, about 15psi probably??? what turbo are you using? standard rs turbo t3?...

 

i don't think you'll make it on a standard t3 from an rst, could be done on a cossie t3 though.
will need remapping and what injectors are you using?
i'm assuming the pistons are standard with using a decomp plate and as such i wouldn't want to push much through it.
but 15psi would probably get you there or very close, just get a bigger housing fitted e.g. 0.48 exhaust.

 

yea thats what i was getting at with the standard t3 bit, a cossy 2wd or 4wd t3 would be my recommendation to, with some greens, and you should easily see 250 me thinks. ask around a bit, fair few people with ZT's now.

 

Ok well ill pick up a cossy t3 then, at the moment I'm usind the standerd fiesta rs turbo injectors, what injectors would I need? And I didn't think the fiesta rs turbo ecu could be re mapped only a chip put in? Or am I wrong? Yeah I'm using standerd pistons for now

 

Motorsport developments could do you a chip. Speak to them about what injectors to use. I;d use VXR injectors, nice and cheap.

 

if it were me i would bin the turbo the injectors and the management
fit some up-rated valve springs
ms2
vxr injectors
cossie t3
and run it 1bar boost max and see what it
does

 

i may sell my cossie 4wd t3 if i can find a t34 or something more suited for my new ZT.
