Ok I think I get it. On a parallel twin turbo setup psi is the same but cfm is doubled. So 24+24 = 24 with double the cfm. Thanks!

So what is the max WHP yall think I can get off my stage 2 gtm kit with these turbos?

I am interested in this as well.

Assuming forged rods and pistons, quality bearings, ARP main/head studs, lower CR, 700-800cc injectors and 3in exhaust... is 700whp possible on a stage 2?

Compression Will have a factor in that , But I'm comfortable saying 650 to 700 RWHP on a stage 2.

Honestly I wouldn't assume anything. To be honest every engine that poped that i know of so far was because of error (error to part meaning example injector failing.) to a part or human. I think honestly we just need someone to beat the **** out of this engine and see what it can do. Seems like we got a great motor on our hand. There is a nissan mechanic around here that has a decent rep and does alot of aftermarket and as he put it when we talked he said we might have another 2 JZ-GTE motor here.

:icon14:

Don't know if it will match the 2jz ha , but it seems to handle 400-500whp day in day out just fine. Only time will tell I guess, being that none have rlly popped due to "power".

LOL i didn't say it. I know those motors are frigging monsters though and were strong. I hope our motors are as strong as that. Hell people were putting thicker head gaskets on the 2JZ-GE blocks and were beating the **** out of them and they were lasting. We need a little more data on what we can do before this motor quits.

Wasn't assuming, it a question about whether the kit with those supporting mods would be able to produce that power.

Thats my whole point behind it. Were making all this power, and we still don't even have full control over everything with this engine yet. Not sure on the gains of VVEL but still we might get something from it

rated at the flywheel of 700 will be roughly right around 600 on. Dyno jet and right around 530 on our Dyno. running the 2860rs out of its efficiency range means your generating alot more heat along with the induced power. sweet spot is right at 17 psi on the g35 we have here. 3.7 with higher compression only will put the Turbo beyond its efficiency at 19 psi. we build reliable power at our shop. overbuild everything to have something that you can beat on everyday without worrying. no number chasing here. obviously this thread and what we do raised some doubts. we have an account with HTML, we do business with Sam, you can't compare his kit to ours due to the fact its on different spectrums. regardless the thread was made on my350z.com to show people there is another option. we aren't here to mass produce it. we are here to offer an honest product built, installed and tuned by us. this what kit make spool quicker or makes more power is retarded. regardless of the spool time, you have to look at how much wtq and whp it makes before it hits full boost. area under the curve.

We are no doubt all hoping that is the case, but I think we are a LONG way off from that at this point. 2JZ could put down 700 WHP with bolt-ons and run for years problem-free. That's why those damn cars still fetch 40K used. 2JZ is in an elite class of factory super-engines. I think the 4G63 and SR20 are up there. And I would go out on a limb to say the S54 of E46 gen M3s (like I had) ended up being a very reliable plant that could take aftermarket FI and make huge power reliably.

Soooo O&G, car8oy281... where's the write up? :D

Soooo Ron, still stuck @ 6lbs waiting on boost controller and stiffer(pink)bov springs because I ordered the softy's, should be here Monday, then we ramp the boost up to 10lbs and see what numbers we get on the dyno. Comp turbo said the turbo will be more efficient @ that psi... We were also working on intake filter sizes, pretty much still R&D stuff, I want to step up to the 3inch intake pipes when Johnny has time. We made 401 whp like 341 or 52 wtq @ 6lbs on a dynojet. I didn't post the vid or numbers because it wasn't that much more than the mustang run we did. No other problems to report, car runs great, good a/f's. cooling is amazing, air intake temps are good, filter is located right where GTM's stage 2 S/C filter is. Cars and coffee in the a.m. most likely if I wake up. I'll update next week after we up boost on the Mustang dyno. Your in town so why don't you just ride in my passenger seat and do a better write up for me!

I'll be there tomorrow morning.. other than "holy sh!t I want boost", I dunno how I can make a better write up lol.
