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.

    • Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks
    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
    • My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
