I purchased my an AMS gen2 3076r when I noticed my manifold and Turbo had a crack. It snow balled into me replacing absolutely everything. I would like to get an idea for the max possible whp on E85 with their turbo... I'm on the fence on if I should sell it while the turbo is still new. It claims it's a 650hp turbo and I've seen an AMS dyno graph showing 493 with their stage 1 motor..... but is there more to get out of this turbo? Is the power band worth it or should I go bigger? Research I see running this turbo is usually a basic stock engine

Sell the turbo. The 30 series turbine wheel is not a good match for the 4b11t. Its just too small to make more than 550 whp. The 35 series turbine wheel is a much better match and spools the same as the 30 series when paired with the 76mm compressor wheel.

I really appreciate you taking the time to reply @chetrickerman . Do you think this would be a good turbo to finish the build off with:


I will be using it for street and track days. I want to make sure I have the best spool/whp combo. Right now my weak spot is the sst (Ill blow money on axles after the tune).... the 10 disk clutch is rated at 600hp which if I remember correctly is whp. My 98 GSX is 600whp so I think in that area I'll be happy as long as the power band and spool are still good for track days. Not hitting 500 seems too little, I would be embarrassed if someone asked how much hp with the money spent.

I have a Gen 2 GTX3576 and it currently makes 521whp on 93. Also there is a guy on youtube called 40RollX,
. Check his comments. I think he is around 670whp with a bigger inlet and built head with cams, but you know how youtube can be.

What other mods are you running? And how much boost? That seems high.

The ATP gen 2 does claim its 750 crank capable. I may go with that atp 3576 gen 2 and see if I can hit 600awhp. It'll be nuts with how fast these MRs shift. If I go up to the 3582 I'll have to change intake and change turbo outlets. LoL sucks so bad taking a loss on new parts. Good news is vividracing is trying to make me an RMA and full store credit on the turbo.... would be so awesome 👌 , I usually always use extremepsi since they hook me up but if vivid does me that solid I'll have to start using them more.

No point in going with a stock frame turbo imo. I would switch to a twinscroll T4 or maybe a V-band inlet. You have a bigger variety of turbos available. Seeing as you have a built block I would go bigger. Maybe an EFR 8474, 9274. Garrett also makes the G35 series of turbos which will probably suit the 4B11 well.

If that is too expensive you can get the Pulsar G35 which is basically a chinese clone of the Garrett but with an inconel turbine wheel rather than Mar-M. They are really popular in the 2JZ community because they are 3x cheaper than a real Garrett with almost identical performance.

For fastest spool though, maybe try the EFR 7163/7670 and MAYBE the new 8370. I know someone that used the 8370 on their supra and it was a pretty responsive turbo. Obviously a 2J is different but it seems like it might work well on the 4B11.
