Tuned up the sr20 yesterday ready for the drags.

21psi pulled 328kw

30psi pulled 385kw

5558 .6 44mm external gate, poncams and forged motor

Theres is more in it but ringing the poor little things neck.

Unfortunately drags got cancelled due to the weather so thats for another day.

Thats a lot of power for a 2L on 21psi, is that on E85 though? Hey Mick O hurry up already with the nats, I cant wait to slap my one on lol..

Yes ethanol. No way would i push 30psi with 98 pootrol

Finally got some numbers but its not done yet,

On the New motor, with the 6262 .84 TS BB CEA.

Run-in tune (super safe) verylow/negative timing, 9-10 psi. 210-220 rwkw.

Turbo is super responsive and perky even with the timing so low, I noticed instantly its very throttle responsive, its very possible my intake setup helps in this regard. But the way it moves the air so quickly I have a good feeling this setup will be pretty decent on the 30/25 with vct!

One noticable characteristic.. the turbo seems very loud. even on low boost. however i am moving from lowmount to high mount during this build, so that might be why i think that.

will be doing real tuning next week if all continues well. Will post numbers as promised when its done. Unfortunently still running hte PFC and Tomei Z32 as no one has purchased the gear yet.

results yet?

Big boy turbo, wha happened to wanting response lol

Yeah, things got a bit out of hand with the engine build and from what I have seen so far this turbo should still have good enough response yet make massive power. Its either this or the 6266. Will see how we go.

I have a 6466 on an rb28, and i expect in excess of 500awkw. Might be a little bit too extreme on a daily strees sil. Buut, look at PJ's THING, because thats what it is, a freakish THING. It has a monster and still makes powers that are usuable for speeding up the rotation of the earth arouns the axis of the suns, and stuff

I think it will be OK.

There's a 180sx 2.0 VE non VVL, with a 6466 that made 536rwk@34psi with quite reasonable response.

Then there's James NFI's S15 2.3 VE VVL, with a 6262 that made 430rwk@24psi with ballistic response (but yet to have final tune).

With my motor 2.2 VE VVL I figure the next size above from James should still provide enough response yet be able to make 450-500rwk should we choose to push it that far.

It will be either a 6266 or a 6466.

Hahaha I laughed pretty hard when I read that! Pretty deep!

Allan, the 6466 on your 26 will be fine and will comfortably make the power ;)

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