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.

    • I'm seeing torque specs all over the place for the OUTER tie rod, but none for the INNER tie rod, where it connects to the steering rack. Even in videos, people are just tightening em up as much as they can with a wrench and that's it. Anything tightened down without torque makes me nervous. Anyone know what the spec is for it?
    • Hope you had a great time here in our tiny country.   The JDM scene we have here is quite small, it's mostly BMW, Volkswagen with burble tunes haha. But the few JDM cars we do have in the scene are pretty nice. Some of my friends drive cool s14's too. Both built engines, red one makes abt 500, blue one abt 400 i think?
    • Ye good idea , would have never thought of something like that. Might aswell do it to every pulley and the balancer while I’m there 
    • Use an LS1 or similar, via kit like Frenchy's. But.... It's probably not the alternator. It sounds like belt squeal, which would be because the pulleys are glazed. Rub every groove on the pulleys with 120 grit paper. Report back. Oh, and new belts afterwards too. The old new ones will be shitted up already.
    • Hello all I have 2 r34 sedans , one turbo one na, only recently aquired the na 34.  Man what is with these things.... My turbo 34 started sounding like a super charger, it was screaming at anything above 4000rpm , I took the alternator apart and replaced the front bearing which is the only one I think you can access and it did not fix the issue so presumably the bearing in the rear of the alternator is gone. ( diagnosed it was the alternator by taking off the aux belts one by one to figure out which pulley or bearing it was )  My friend gave me one he had lying around, Installed it , it did not squeal for maybe 500kms and now its started to squeal again briefly on startup  Recently got an na r34 and I replaced the timing belt, water pump + all the auxillirary belts. Runs amazing but it suddenly developed the same squeaking problem but significantly worse, Ive had my neighbour come down screaming at me because it was waking her up everytime I moved the car. It takes a good 2 minutes before it quietens down.  Im yet to diagnose where its coming from but im fairly sure its coming from the alternator aswell. My question isnt about how to fix it but rather where can you get a new alternator for an rb25 neo??? Ive searched everywhere but I havent been able to find a direct fit oem type replacement thats not genuine. All the automotive stores sell an oex one - BXA035 - which I picked up for cheap through a friend with staff discount , got it home only to find the connector is completelty different.... As far as im aware bxa035 is for rb20/30's and after a bit of figuring out the bxa035 has an ev14 type connector, which is tiny compared to the rb25 connector. I actually had an ev14 connector lying around which I was considering just replacing the bigger plug with to get the alternator working but the bxa035 is rated for 70amp vs the rb25 alternators are 90amp ( or so ive been told ? ) That paired along with the fact im about to install an amp + sub in the back and I have the stock sized small battery Im not sure itll do the job unless anyone has another opinion?  I know and have seen all the websites selling the ls1 alternator conversion kit but I am not going down that route, nor do I have the money to. Hopefully I can figure out how to get 2 brand new alternators for both cars. I would buy second hand which there seems to be many of but considering how common this seems to be im sure If I installed a second hand one it would start squealing in no time  Or even better if anyone knows how to fix the issue directly with the alternator itself... Any input appreciated Thank you     Link for bxa035 connector picture
