Hi all as above...also is my manifold knackered ? see pict with arrow.








cheers

 

pics aren't great, one of compressor housing is of little use to be honest, the overall pic shows it's a cossie exhaust housing, possibly a 2wd cossie turbo, or a hybrid of an escort rs turbo on a cosworth exhaust housing at least.
what is the A/R on the exhaust housing?
if 0.48 it's the same as a stage 3 t3 turbo for an escort.

as for manifold, could just be a casting imperfection, they don't tend to crack as a rule unless running mega lean. If that is the case your pistons should be on the way out too.

 

it says a/r .42 on it aint that a standard 2wd turbo

 

the escort rs turbo also has a compressor A/r of 0.42, as does the 2wd/4wd ones.
it's not the A/R that's different, it's the compressor wheel size/trim and housing that is different.

 

whats the best way of checking this? Also is it worth keeping the cossie housing? Reason being, im going to be getting the exhaust sorted (additional hangers and poss a flexi put on) and will therefore be getting a downpipe sorted

 

The Turbo setup on the car is the best for free flowing on the std setups so keep it as it is if its all working.

However fit an intercooler.

 

Cheers ,

Definatly need a proper front mount so I can ditch the crappy chargecooler

 

One more thing, should I get a spacer plate made between the manifold and turbo housing as it seems to be very close, if not touching

 

no just grind the alloy a little but dont go made.
