Building a 1.8 zetec turbo, blacktop.

Unhappy with the way escort rst manifold matches up to zetec head so looking for a zetec suited manifold and came across an american company who do turbos too. cheap enough for a new unit.

Is there any reason not to think that it'll be ok? I mean, its a brand new turbo and looks decent quality. They've got decent feedback too.

Question is though, what size housings are best to go for on a 1.8 ZT.

Ive narrowed it to this:

.42 A/R Compressor

.48 A/R Turbine

and this:

.50 A/R Compressor

.63 A/R Turbine

Im aiming for about 200ish and similar torques. C/R should be around 8.1 ~ 8.6 dependent on final build height with pistons ive chosen.

Im thinking the smaller turbo would be better since it'll lag less. It's going in a cab for now so dont fancy chasing power figures.

Final question. Is there any advantage to a V-Band on the exhaust housing? I guess it'd be easier to remove but im not sure if its worth bothering or not?

Cheers in advance!

 

Anyone?

 

better idea to post in general?

 

Hi mate, buy the may issue fast ford mag, its got everything u need 2 know bout tuning both black and silver top zetecs, and im not joking when i say everything. Hope this helps and points u in the right direction

 

Cheers mate. Was more a turbo specific post than zetec though. The zetec bits are figured out

got the mag day it came out though

 

just get a 2wd cossie turbo or 4wd cossie turbo and stick it on your manifold.

 

id like more thought into it than that tho lol...
