Overall though don't be surprised if it's still a bit lazy'laggy even after a tune.

As scotty said a 100m cooler, is not really a smart choice regardless of price.

Probably would've been better to sell and buy something more appropriate.

I would just put the stock intercooler back on. If everything else is standard that was not a good first choice of modifications.

Yeah just got the car so goin to get a boost controller nxt week wat u reckon it's safe to turn up to with stock turbo

I always liked the stock cooler with the stock or R33 turbo on the RB20.

If you dont plan to do many mods Id just put the stock cooler back on and sell this one like the guys are telling you.

An R34 sidemount will be a good upgrade for it and will be a good match to the stock turbo on say 12psi. You will probably get away without a tune too, just put it on a dyno to check AFR's and keep rocking.

The car is almost stock. Splitfire coil packs full kakimoto exhaust everything else is stock do u guys reckon a 600x300x76 fmic is to big

Well you may as well leave the 100mm in now that it's installed , wind up the boost to 12 psi and see what it feels like.

Intercooler upgrade is a supporting modiication, not a power one. It's a modification you perform when you are planning big power upgrades (bigger turbo, aftermarket ECU etc.). If this is not what you're aiming for, then it will probably hinder you more with lag than it will benefit you in keeping the intake charge cool. The standard intercooler has been matched perfectly to the standard engine and will be doing a fine job of the latter - bigger intercoolers with more piping generally result in a laggier feeling engine, but are great when you start pumping more and hotter air through the intake system.

That said, many (myself included) report better performance (or more correctly, a lack of "lost" performance) operating in hot environments and under heavy load after installing an FMIC without tune or power upgrades.

Don't listen to these homos, you have the cooler now go get yourself a t67 turbo, a highmount manifold and plazmaman intake..maybe an 80mm throttle body too..chuck in a motec engine management system and 2 big bottles of Nos.

Wind boost up to 2 bar and enjoy :D

Or you could weld the actuator shut?

Cheaper and more efficient

    • 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.
    • Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.
    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
