I HAVE A ENGINE BEING REBUILT NEXT WEEK FOR MY R33 GTS-T (LATE 1995). I HAVE ASKED FOR THE STRONGEST POSSIBLE ENGINE WITH AFTERMARKET PARTS FOR ABOUT $5600--$6000. CAN ANYONE GIVE ME SOME IDEAS ON WHAT TURBO (NEW) WOULD BE BEST SUITED, IF MY STOCK ONE NEEDS REPLACING (IM CONSIDERING GARRET TO3/TO4)YELLOW, AND ANY OTHER MODS THAT SHOULD BE FITTED TO KEEP THE NEW ENGINE HEALTHY. EXISTING MODS ON THE CAR INCLUDE - APEXI (GT SPEC) INTERCOOLER, K&N POD FILTER, Z32 AFM, JASMA 3.5INCH EXHAUST - WITH 4 INCH TIP, BLITZ DUAL SBC EBC, (NEW) WALPRO 500HP/255L.P.H FUEL PUMP, NEW HKS SSQ B.O.V., ORIG- NISMO FRONT STRUT BAR, NEW CLUTCH, FULL GTR BODYKIT,18In LENZO ALLOYS, NEW BRIDGESTONE POTENZA SO3'S 235X40(FRONT) & 265X35(REAR). IF ANYONE CAN GIVE ME ANY OF THEIR IDEAS ON THE ABOVE AND ON HOW MUCH HORSEPOWER/KW I MIGHT BE ABLE TO PRODUCE WITH THIS NEW ENGINE, IT WOULD BE GREATLY APPRECIAITED. PHOTOS TO BE POSTED SOON!

mate i had my engine rebuilt too and i went the hiflow t3/t4 currently with the microtech computer and 14psi i am pushing out a bit over 300hp at the wheels. I recomend getting a custom turbo manifold, i only have the standard one but am going to upgrade soon. u will however need bigger injectors and perhaps fuel regulator to cope with the increase in power if u are going to run a bit of boost. My turbo starts to spool at arounf 2700rpm and is a full bost by 3600rpm

hope this helps

im not the one to know the best internal stuff but you'll need an oil catch can and definatley at least 550cc injectors, fuel pres reg, id also recommend a custom manifold so it flows better than the stocky ones, im in the process of doin the internals so if anyone has good idea's that would help 2 of us...

cheers...ben.

Thanks mate, I think will go with 550 injectors and a fuel regulator and the manifold. I will have to shop around to find a good deal.

Thanks Ben, I am going to source the injectors,oil catch can,fuel reg and the manifold. Do you know what sort of price I'm looking at?

CHEERS, Chris

Thanks Davio, Can you give me a idea where to source a microtech computer and prices involved? I have located a Apexi power FC, but maybe something cheaper?

CHEERS, CHRIS

get the PowerFC.

And take it to RacePace to get it tuned. I would also suggest taking it there for the motor rebuild too if you aint already laid out cash

As for turbo, what power you want?

I'm running a GT30 (600hp) and making ~270rwkw on 16psi at the moment.

RB25 rebuilt with forgies, and GTR rods.

Thanks, I had a look for contact details for RacePAce in the yellow pages online, but couldn't find it. Can you help with the number/site? The engine dosn't start to be pulled out until next Friday and I am at the moment getting Cavehill Engine Services PTY LTD in Lilydale to do the build the engine as they have done a number of these engines and I was referred to them by a Turbo/dyno specialist. I will contact RacePace A.S.A.P

      Mistakes were made, my R34 Story

      By MBS206 · Posted

      The real question is, on some of those wild roads they call highways, how many times did a farmer in an old ute from the early 2000s blaze past you over double lines?   Tassie is a wild and really cool place, and after doing a work related road trip there January of 24, I understand why Targa Tasmania is ran there, and is so tough to do well at! We had a brand new Camry Hybrid that handled quite nicely, and thankfully weren't in an old car, because cresting some of those hills in a 100kmh zone for it to suddenly be like "surprise f**kers, this is a recommended 30kmh hard right turn" wouldn't be pretty. We weren't racing the Camry around, but we weren't slouching in the bends either. But my lord those old farmers know their old clapped out utes, and those roads, as they were absolutely hammering it!   You're also super lucky to make it up to Mt Wellingtong this time of year. It's often road closed with snow/ice! Also, I hope you hit up Salamander Road in Hobart for some insanely good food (I highly recommend the dimly lit Irish pub for a Guiness Pie, or even the bangers and mash!!!)   How long did the Ferry take to get across? I want to do a road trip of Tas on my own time, but I get horrifically sea sick, and I don't want me on the Ferry, just the car 😛

      Hmm not really, I'd say its race car life or modified car life when you make 3 or 4 times the power Nissan designed the car for lol.

      I'll let others with more breakage chime in, but I can't think of anyone who had a problem with the standard centre plate before they had a problem with the standard gears - the plate generally just gets replaced for safety when the gearset is upgraded. As for the gearsets, its not like they are OK at 600Nm and break at 601. Their longevity is a combination of how much torque you are making and how gentle you are on shifts (or not).
