what do you think this would be like on my saph interms of functionallity and performance?
max power?
peak power in rpm range?
possible surge issues?
amount of lag
etc

spec is
standatd comp
bd14 inlet cam
rewelded inlet manifold elbo with 10mm spacer plate
2wd ex manifold
ported head
around 2-2.3 bar boost

any idears or any one tried this

 

At a guess lag city, question is would the 55 housing limit the boost enough so that it would do the boost you want on a T4, I'd pm Nash as he loves the T4, wopuldn't be surprised if he'd used this combo, worth a pm anyway.

in theory a smaller rear housing should make it less laggy compared to its origional o.63 housing. iv just pmd nash, hopfully he will advise me
im just iching to do something with this t4 that i got, their aint many exhaust housings out their that fits the t4 turbine wheel, im struggling.
cheers Tabetha

 

i happen to have a .55 for sale

 

Dicko you have pm

 

As you say in theory it will be less laggy, but I wonder how fast it needs spinning to generate noticeable boost with a T4 ?
