some S15's came stock with a ball bearing version, others got the same one that is on the S14.

they are steel wheeled so can be boosted higher.

anything over 17psi is just blowing hot air though.

An S15 with stock turbo, along with the usual supporting mods on 17-18psi will make almost bang on 200rwkw.

the factory T28 off a GTiR is slightly better in that it can flow more.

but the ball bearing one off an S15 is the pick of the bunch.

having said all that, it won't bolt on to a skyline and would not make the power that an SR makes.

why won't it make similar power if fitted to a skyline, they are similar sizee to an rb25 turbo?

haha thats a 50kw difference...pretty unrealistic if you ask me...

yes 18psi will net you just over 200kw on a SR.

no dont put it on your skyline. why do you think its the same size?

FYI the turbine inlets are different, dont bother dude.

aus spec s15 and s14s come with the bush bearing version of the t28

jdm s15 come with the ballbearing turbos and with basic mods comes a fairly easy 200rwkw

      I have driven it slowly around the block, didn't notice any issue with the brakes. It is a vacuum brake booster.

      Stock speakers / head unit functionality

      By Sleepergm · Posted

      Hi all, so some of my speakers still work some I don’t think work. The old head unit is still all functional. If I keep the stock head unit as I feel it’s vintage then can I just pop in new speakers - would that be plug and play? Would I need to bypass the amps in the doors and back? Heard there’s 3 of them.  anyone run a blue tooth into the stock head unit? Or is the only option running one of those tape decks with cable coming out?  my cd deck controller although rare I don’t think is working anymore either. Guess if I got that working with the speakers then I could load some cds.    just seeing my options here if anyone has some advise.

      My trusted mechanic is Tunehouse in Calder St, Marrickville. He's the guy who did the ECUtek dyno tune on mine. I'm nearing the 85k mark for my motor and I'm considering getting the oil galley gaskets done as preventative maintenance when the time comes. Since my garage isn't big enough for such a task, I'm definitely going to be handing it over to him. You'll be impressed by how clean he keeps his workshop. It gives you the confidence he and his employees will look after your vehicle with the same pride.

      The Bogan Sports Car now has fresh gear bag and diff oil The old gear bag oil was nice and clean looking, the old diff oil was average looking, not horrible, just dark, I've seen worse in other cars, much worse Good things was that both drain plug magnets looked good with zero bits of anything apart from a small coating of that typical black goo you get on the diff plug, it was probably the original diff oil, but nothing shiny The shifts are sweet, and the Torsen is Torsening like a boss (tested in the work vehicle maintenance yard after work). LOL In other noise related news, the Racing Beat axle back sound nicer than stock from outside with the roof down, but still pretty quiet, but it's not noticeable at all really inside with the roof up.....maybe it needs a header.....🤪  This is what a OEM header looks like 😝 > 🤣🤣🤣🤑
