Hey guys and girls,

So ive got my hands on a rb30 block and i have a r33 gtst. How would i go upon making the infamous rb30? my block is bored out to 87mm honed and decked. i know ive got to modify my rb25det head slightly for it to work with it but ive heard a neo head works better ? is it true and if so how ? also what pistons would i need to you and crank. budget isnt really an issue for me i just need info i get mixed numbers all the time.

Ive got a 3 layer cosmetic head gasket also, ill be running 272 cams and ill be installing stiffer springs and upgraded lifters and all the supporting mods 1000cc injectors and all the good stuff. Once again my goal is anywhere around the 600 hp mark. i have alot of experience with engines as i have grown up around them but never really rebuilt one alone and which is mine..

Any help would be great thanks.

600hp (330awkw) is pretty straightforward and should not require anything special....as Bob said just follow the well worn route. Even if you want 600hp atw (450kw) it's well within the ability of the combo on e85 with the right turbo

you'd put smaller cams in it for a start...272 and rbs are a good receipt for breaking shit, revs are not your friend, you want area under the curve..and lots of it for a streeter

small cams/ stock intake runners/.decent comp

600hp is pretty much a stocky, built right and tuned well..the vl turbo guys have been doing it for a long time..since the mid to late 90's ..skyline guys just take no notice..lol

and twin cams are far easier than a sohc head

Just depends what you personally feel comfortable with doing and your budget

cheers

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
