+1 :) even though mine isn't the cheapest of cheapest RB30 builds it's far from expensive.

I'm aiming for 400rwhp when the GT35R goes on, I think this is going to be the upper end of the drivability limits of my rwd 32 platform and with my setup I'm probably going to be struggling to keep it down that low for now! There is still headroom for a bit more power too ;)

Personally I wouldn't waste money on the RB20 but, of course, I'm biased. The monster torque of the 30 makes for a very nice allround car, I mean I was following Tristan through the twisties on Friday in 4th gear up those hills.. the ol' RB20 wouldn't have liked that much..

+1 i am doing the same thing and building an rb35/30 its fairly cheap to get an rb25 and an rb30 block is even cheaper but remember if you want a reliable engine you are going to have to spend a fair bit of money have you taken everything into account that you will also need to buy?

I think iv made my decision..... i think ill be going for the 25

i think the cost of a 25 could be a little better and it also means ill have more cash to add my big turbo n clutch and so forth ;)

I cant wait.... now ill be in the hunt for 25 half cut so if anyones knows of the ideal place/person to get a well looked after 25 then this would be greatly appreciated. otherwise ill find one :happy:

Man the 25Neo didn't even like it...

I mean it 'managed' in 4th, but def wanted some more down low balls.... Sometimes, knocking it back to 3rd was required to keep up with the cars ahead...

btw, I think go either a 25 or 25/30 combo engine... Make sure you get a NEO so you've got solid lifters and NVCT on both the intake and exhaust...

yeh i thought about a NEO... will that go in with no hassle like the 33 rb25 or they basically the same.... i wouldnt mind a neo because its a newer engine

Too many hassles :nyaanyaa:

BTW my drivability through the hills the other night will disappear when the big turbo goes on.. because power is so early and delivered so linearly is great but once new turbo is on I'll only be able to floor it on the straight bits :(

Umm.. even then I wouldn't be able to floor it until the straight bits.. VH41 + TT would just send me into a tree faster :nyaanyaa:

To be honest though, with the 3L + GT35R I should have decent low down with absolutely insanity over 3000rpm :(

if you want a 26 your better selling up and buying a gtr but if you'd like to go down the path of a 26 in yours with rwd setup easiest option is to buy a half cut as you'll have everything in there like all the hoses front brakes wiring resistor packs front mount intercooler+piping and yeh

same with the 25 get a half cut all is there like brakes, wiring and hoses and shit

cheers

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

      By GTSBoy · Posted

      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!

      Mistakes were made, my R34 Story

      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...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
