Wishing to obtain some more power from my engine than the actual 518 whp
( read on a Dyno Dynamics dyno bench )at 32 psi with 100 oct Shell Vpower, i would have decided to make 2 upgrades, the first is a set of Tomei 280 cams, lift 11.8 mm instead of the actual HKS 272's, the second would be a bigger turbo (actually i have a GT35R, AR 0.82); a GT42R setup seems to me a little too big, and, after reading on this forum my choice would be a Precision PT67R dual ball bearing, with T3 inlet and exhaust AR 0.82, could it be a good upgrade for me, considering my engine spec? ( 2.3 stroker with Crower billet crank and titanium rods, Wiseco pistons, 1200 cc injectors, Magnus intake manifold with 76mm throttle body, Shearer exhaust manifold with Tial 44mm wg, ported head with +1mm valves, dual Bosch 044 fuel system, D-Jetro Power FC + AVCR, upgraded intercooler and all usual other mods )
Please, could somebody tell me where i can purchase this turbo online ( i live in Italy, this is my only option....), as on Precision turbo web site there is apparently no trace of it ( or more probably i don't see it )?
Do you think i will be able to obtain some more power with these two mods?
Thanks....
Gianluca.

Thanks for so quick replies....
I would need a T3/T4 flanged turbo, for retaining my exhaust manifold, and more important, for having not to hand build another downpipe different from the 3inches 4 bolts one i actually have ( this is because i have a Lancer Evo TME, practically a Evo VI, and nobody builds a specific downipe for this model, it's different from VIII units....), so a T4 turbo would not be a good choice for me.....
BTW could somebody confirm me that swapping from GT35R to this PT67R is a real upgrade?
Thank you for patience.....

 

u want the same setup igot.shearer has the turbo.

 

Ive installed the evo VIII dounpipes on V, VI, tme VII all I did was custom make the support of the dounpipe on some cases (stock turbos) you just have to swap the o2 housings

 

It is a definite upgrade over the GT35R as far as the compressor wheel goes. It will support about 110hp more than the 35R wheel. I have used this turbo on several projects with very good success. I built a RB25powered 280Z and it put 618hp@wheels on pump gas, 20psi and some Nitrous. This is using a bone stock longblock. Nothing like whipping a TwinTurbo Hennessey Viper on the street.....two races in a row
BTW, both cars were on pump (93 octane) and both cars were on street legal tires.

RB25 280Z vs TT Viper

 

Thank you for confirming that, i was a little worrying about lag of a GT42R, this setup, together with more aggressive cams, should be a good compromise....

 

with the PT6776R you have these options..

S or H compressor cover
T4 Tangential Turbine housing w/ .58A/R, .68A/R, .81A/R, and .96A/R

I would recommend the .81A/R...although most people would prefer the .68A/R

All come with 3" V-banded outlets (actually 3 5/8")

We sell oil line kits for these, coolant line kits, gasket kits, and all the flanges you'll need to fabricate your own downpipe for it.
