turbo,valves,cams...questions

[Carmageddont231]

I build a turbo 2zz under gt35r for drag race.
I need in approximately 450whp.
-Pistons mahle 9.0.
What will be effect from installation camshaft piper st2, st3. Mine cams and rockers are worn out. I face to a choice. The drain is much cheaper. Whether and if the difference is insignificant for an engine turbo it is necessary to spend money?
Whether there is a necessity for the strengthened springs of valves from mwr....
And considering mine specs on what turns the specified capacity will be reached?
Whether correctly I understand that the indication for replacement of valves and springs is not power, but only only raised maximum rpm of the engine.

Others have ran huge numbers on the stock cams. If you do go aftermarket, go with the stage 2's. the stage 3's cam lobes and angles are not meant for FI. They will give you better #'s at different PSI, but it's not necessary so it'd be purely by price. They would improve your low end #'s though, but again, it's not necessary for drag racing where your in the top end the whole time.

You will benefit from Piper Stage 2 and Stage 3. In order to choose between the two you have to think about the following:

a) Are you willing to rev beyond 9000? If so, will the turbo be able to push enough air that high?
b) Can you control VVT?

If yes for both of the above, Stage 3 are the best choice for you. If not, then Stage 2 are the best choice.

The difference for the cams will be more mid power and a bit more top end power. You should expect something like 30-40hps for this turbo setup. If you think that it's worth the money, you can go ahead and buy them.

As far as I know, stage 2 and stage 3 cams need upgraded valves and springs.

What will be a real increase with piper st2 or st3 in horse power from wheels in comparison with stock camshaft?

Unfortunately, I do not know to what rpm to me it is necessary to twist the engine to reach the set capacity in 450 whp on the gt35r.
I need to know it that I will answer a question to rpm turns to twist the engine.
b)yes a can control vvt with pfc

piper st3 can give me more power?what in compare with st2?
and st2 in compare with stock?
give me two digits(approx,in whp)

An estimate is already answered and it has to do with stage 2 cams. Noone knows here about stage 3 but my guess is that it should be 10hps+ (from the 30-40 of stage 2) if you rev at 9k or above.

i made 545HP on stock cams and MWR valves and springs. dont waste $$$ on cams

545 whp?
rpm?
manifold?
turbo?
pressure?
specs engine?

just search ;)

the GT35r is more than capable of 450whp with a built motor and stock cams. you don't want stage 3's for FI purposes, there is too much overlap. Even though the lift is better, it's redundant since your FI and not NA. go with nothing or stage 2's. purely on price.

peoples!thanks for ask on the my stupied questions ;-)
I have already bought
-mahle pistons
-circuitworks gear
-standart rods bearings mwr

my intake camshaft, two rokers are damaged ,lift bolt cracked
it's road to stock cams and new rockers for me as your think.it's poore and work.

i want to by next:
Correct as consider it necessary.
-mwr or stock bearings of crankshaft(why people by mwr?)
-arp head and main (i need in?)
-mwr valves and springs(is it need?)
-mwr rods(Very much it would not be desirable simply so if standard are strong enough, what you can tell?)
-manifold for rhd(Who can sell ready or make it for me, considering that I am in Russia and I can not give the car for measure.)+westgate(tial 44mm)+gt35r
