hypergear highflow or ss1pu .64 for 230ish kw, complete bolt on no hassles.

TD06SL2 20G 8cm for 260kw if you want full external gate no expense on supporting mods spared.

personally I'd put a ss1pu in stock housings on an RB20. Wouldn't even need to think about it.

My predicament is that whilst building a 25/30 id like to have all the neccesary bolt ons ready to go. I dont want something that is too small for the 30 or something to big for the 20. Dont know if that is practacle though. Could a 10cm housing be the way to go when the 30 is fitted. Not after a big power figure just nice reliable engine.

what your wanting is pretty far fetched. its two different ball games unfortunately, and what will be laggy on an RB20 would still be too small for an RB30. thats how different that are.

its really wasted money getting a tune and all that then putting in a bigger motor and needing to do it all again. a turbo that will work on the 30 will just make you cry on the 20.

a nice reliable setup for your 30 though, you can get a hypergear G3 turbo which is more or less a bolt on with the stock manifold and dump pattern. there are videos of a RB30DET R33 with a basic G3 bolt on smashing a 600cc bike on here somewhere. Epic fast it seems, go check it out.

yet if you got that turbo on the RB20 you would need a tiny housing which would still be laggy.... and using the correct housing would be horrible on the 20, and a waste of money to do both as stated prior.

i say wait till the 30 is built.

My TD06-20G is off a twin GTR setup that upgraded to T67s. With a couple of Greddy manifolds one of the TD06-20Gs ended up on my car and the other Fatz's RB30. At the time we were both running 10cm housings and on the 2L RB20 it was too doughy. Changed to an 8cm housing and everything improved. Meanwhile Fatz made something like 245rwkws on 13psi on 98 on his RB30. So would be an animal street car if you ran it to 18psi easily maxing out the 20G compressor without the need to rev the ring out of the engine....

...so I tend to disagree that the same turbo cant serve two different engine provided you are willing to swap A/R of the rear housing

its certainly not that it CANT do it, but rather than you wont want to.

sure enough it will work, but for the effort of a full external gate setup on a heavy breathing RB30 I cant honestly see that it would be justified to make 240kw..

plus, the easiest way to do this setup is hanging a gate off the ex housing and using the stock manifold. if he hangs a gate off an 8cm for the RB20 and then buys a 10cm for the 30 he then needs to get the gate moved over.

just flat out sounds like money is leaking away and overall performance is not on par.

Just saw Fatz made 240rwkws at 10psi :) easky_mad said he is " Not after a big power figure just nice reliable engine" A 20G on whatever boost maxes out the compressor would be a very grunty street car and probably one have to run a very durable 13-16psi. He said he also says he has all the bolts ons ready to go so I dont think it would be a bad option for the situation as he explained it.

A T67 would tilt the balance towards the RB30 with it being a little less suitable for the RB20 but he said he isnt after big power so I take that for a range around what a 20G can do

let me guess you dont like the kink on the straight?

I was never game enough to take it full throttle hey lol...

Full throttle 5th gear right until the kink :) td06 loved it 1.09 in my gtst. Heaps more in it too. No traction tho. Needs a better setup rear end

1.09 pretty good jez..you running stock brakes and all.. Its not the kink i had an issue with, iys pulling the car up after it..lol..I did it flat out to kink the first time, then lift turn brake and nailed it, got 1.17 still..then came off hard on the second and think I kinda lost my nerve after that and resorted to a quil brake dab before the kink, I did have to drive back to Melbourne that night after all...made up heaps of time on the rest of the track and pulled 1.16s all day pretty much..

how were the intima pads jez? I want a set of those also. fark 1:09 is fast.

best I ran was 1:18s, if any of you are on my FB watch the video. I have intentionally edited out the bits that show my car being out horse powered by fairly stock honda civics lol.

the worst part for me was having no real power until 6krpm and the stock 3.7ish diff in the S14. for the most part of the track I was bumbling around in 3rd with no real power.

Ill try post a video tonight if I can.

I wish I had that sort of problem with traction

Makes it exciting. I loved the rush and excitement of RWD on the circuit and not caring if it got smashed up :)

VCT is now working on my gtst, i installed an adaptronic and its working brilliantly. Very inpressed with the Adaptronic ecu's.

    • Well, in the same way that you can't tell any SUV from any manufacturer in any size category from any other one, "sports" coupes now all look identical. Stand back and squint your eyes and the Supra and the 400Z and the GR/BRZ things all look the same. I was just thinking last night, when sitting behind a Subaru CrossTrek, that I have no idea what it is, how it differs from an XV, or a Forester, or an Outback, or anything else Subaru offer, and I couldn't tell if it was supposed to be small, medium or large. I contrasted that to the good old days, where a HQ Kingswood had familial similarities to an LJ Torana, but there is no way that you could confuse them, and how a bit later, the HX Kinger and the concurrent Torana and the Gemini all had familial similarities, but you still could not confuse them. Ditto the ugly Fords and Chryslers of the era. But now, a RAV4 looks like a Kluger, looks like a Yaris/Cross/whatever they're calling those stupid f**king things, looks like every other Toyota that's not a Camry/Corolla sedan.
    • The Prelude doesn't look that bad without all that lens distortion in those pics. Makes it look disproportionate when it isn't. Actually I kind of liked it at the Osaka Auto Messe earlier this year. 
    • Pour in the highest octane, non-ethanol fuel you can get and see if the readout changes. If it's dead bang on 11% then I would question the sensor. Another quick test, just take it out and run normal (in an american accent) gas-o-line through it and see if the sampled ethanol or lack of changes.   United E85 here in the land of drop bears does vary a bit, I've had as high as E87 (could be water in their tanks too, who knows)
    • Yep. And if you ever do, you'll just have to deal with it then.
    • E10 is pretty tightly regulated in percentage. Too much and engines can't adapt. Every incentive is against them to have too little ethanol though. The more ethanol the higher the octane.
