i have a Turbonetics TS04 with a .96 A/R and a P trim wheel, it had an apex seal go thru it and it needs a rebuild . should i go with a Q trim wheel and will the turbo shop need to machine the turbine housing to fit the Q wheel or is it the same as the P trim wheel?
here are my mods:
MZM performance Race Port
PFC with 2 850s and 2 1300s
Rebic 3 and 2 720s
and a 4 inch MP and EX.

i know that i should have enogh fuel for 500whp and i have a good tuner ( MZM ) but will the turbo do it with a Q trim?

 

help please

 

Stick with the P trim. The Q trim would require machining the exhaust housing. On the side ported motor you will be much happier with the P trim wheel, won't fall off on the top end and alot cheaper when you send an apex through one.

 

Q trim advantages; Bigger top end. More efficient design. If you are happy with your power output stay with what you have, if you are not try a Q trim. Is your manifold divided? You can buy a Q trim housing for ~125.00, that with the bigger wheel(Q trim) should give you another ~30-60hp on the big end with slightly(100-200rpm) slower spool. You should also see a nice torque gain in the mid range. Carl

 

i'm not sure yet about the turbos out put on my car, i bought the whole kit used and the previous owner made 480 whp at only 18 psi. he had the PFS Box and ran a rebic 3. he told me that Adam Sewattari (sp?) tuned his car and that Tri point engineering put the kit together for him. he was also running a race ported motor and i'm guessing the timming was too advanced to make 480whp at 18 psi .

here is a pic for the manifold and turbo:

 

Holy big pics!

That manifold does not look too capable... Anyone else agree?

 

sorry about the pics i don't know how to resize them
