I think I will really see that with my current motor

It's there for the experimental purposes. I'm planning to upgrade to a 6-bolter after I'm done with this one.

WHITE_SHARK

LOL, yes I would race you Faisal, you without turbo and me without engine lol

Sam, Who spoken about GTRs? these cars are scary fast especially in our silky streets in Riyadh! but your MC performance zr1 with nos done the job prettly well for the 900whp GT-R

We had yesterday Chris from AMS locally here in Saudi Arabia tuning some Evos and GTRs I had a small interview with him as he tune American's cars as well

this kit is great just the T3 flange is a HUGE hold back. no matter how big of a turbo you put in the T# it just wont be able to move enough exhuast gas to stop form huge back pressure.

i think the t4 flange with a 3" vband and fit the biggest DP you can.

Z06-TT

this is the issue with these turbos. the T3.

the 6766 would be a great upgrade with a t4 flange. but if going to go to the t4 flange i think the 7275 would be a much better choice for his 1200 Min wheel horse power. the 7275 will give him room to grow.

plus if you go with the bigger motor then it will be a rocket.

Drewstein

Haha that's awesome. Maybe you can set the 4-bolt record. I'm sure it's around there.

Man thanks for the great feedback and now I'm talking to a couple of shops to do the T4 flange and the 3" DP.

But since I'm doing all of this, why not go with the 7675 instead? I just can't take it of my head.

fe9_fe9

Only time will tell my friend

Z06-TT

we can do that turbo also. just think the 7275 would be a fun little street rocket. spool qucik. make great power.

but in the end it is your car, your build.

i wish i was closer. i would do that t4 and 3" down pipe. for you. lol

venomws7

Thats a I'll make sure I have my and you better bring the Mod






So any numbers we should know from the GTRs that Chris tuned?
We just finished tuning 1072whp GTR R35 this car ran 9.3@153mph with only 950whp The car will be sick on the street

I'm talking to the ZR1's owner for Stage 3 build




I'm sure we can help him with T4 & 3' DP swap
I also agree with 7275 turbos 427-440ci engine Faisal's goal may be close.

7675 turbos are sick but it will be perfect for 454+ci Tall Deck if he can fit it

Now you're talking baby

Just pick up the damn phone!!

Z06-TT

Faisal, i will get you info before the day is over. just super sumped at work.

1400 hp on **** water fuel + meth......lol ok. Real fuel>Meth bandaid.

As for the 4 bolt head thing, I've seen way more power than that on a set of four bolt heads. So that shouldn't be an issue if your tuner has any ability.

As for turbos..let me get this straight you are wanting to run twin 76's for only 1400hp?

fe9_fe9

Ok, you seem to know a lot and you can help me. So fuel is 91 + Meth. 4 Bolt Heads on an LS2 402 (for the time being, will go bigger later). Yes, let's shoot for only 1400 RWHP.

Help me "properly size" my turbos

Drewstein

76s do seem high. Maybe 67s would be a better fit.

You also don't want that curve to look like a ski jump. Power under the curve is more fun.

Z06-TT

I recommend 7275.

Vert_Fan

And you would mount these where exactly?

greerracing

In the fenders if he uses the kit he has.

Z06-TT

yep. doing some size checking but that is where they will go.

to do a little updating. the current turbos the customer had where about the same size as 7275 turbos. so the fit will be pretty easy.

and should rock with the 7675 pair he bought.
