Yeah it looks the good, my only concern is the cut back turbine wheel compared to the 83-75, will have to try and find back to back results to see whether the extra power will overrule the extra lag lol.

Im after a mid 10 1/4 in a 3800lb Soarer...so Ill be needing 400+

Rekon a 83-75 will do that on E85? might need 35psi...but Im ok with that lol

Edit - Im basing this off Guilt-toys 380rwkw r33 which went 10.8 at 130something, my car is a bit heavier, but is auto, so by my rekoning 380-400 should get me where I want to be.

More is always a bonus though lol.

Not looking forward to getting the quotes on having the trans done to cope lol

geoff at full race recommended the 83/75 to me,..

I too am after approx 400rwkw though im doin it on 98

my set up included a built engine, mild cams, cam gears, 800cc injectors, large aftermarket cooler..still using 2.6L

im assuming u would be able to get 400rwkw on E85

well if Geoff says its a go, then I'd be oblidged to believe him.

What rear housing are you using? split .91?

1JZ's tend to need a bit more boost than RB's to make the same power when using the same turbo....having smaller ports does that.

400kw on E85 should be easily doable with a S300SX 83/75, even through an auto imho. If you're not shy on boost and setup on E85, then depending on the dyno I'd say well more than 400kw should be doable.

If you're "only" going for cracking tens with an auto Soarer and willing to go 30+psi on E85, I'd lean towards the S300SX... once you start going larger building boost against the trans might start becoming a challenge, unless you are going to use NOS.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
