Yes it is the 53mm one.

I built the engine myself and it definitely goes past 90, but if I keep the revs up above 2k, it drops slightly. The problem started after the re-build which is the same time I installed the new rad. Already bled the system twice. No change.

Would an N1 water pump help?

Yes. Standard viscous.

Just completed a re-build: JE 87mm pistons Tomei OGK - 1.2mm ARP Head studs Cosworth Bearings - Std Tomei Poncams - 260/260 Apexi PFC - D Jetro Koyo 4 core Radiator N1 oil pump Mishimoto 62c Thermostat GT2860-5 Turbos Mines Titanium DP 3.5" SS Jasma Exhaust Car runs well and maintains water temp in the 70s and oil temp in the 80s when driving. Problem is when idling for more than 10mins, water temp rises to 90c+. If the car is parked soon after, about 200ml of coolant flows out of the expansion tank. Advice?

Thanks for the tips guys., Opened up the bottom end and noticed conrod bearing # 1 seems to have spun around a few times. Luckily the crank seems fine. Have ordered a set of nismo bearings from nengun which I'll hopefully get in the next couple of weeks. Any suggestions with the running in part?

I hear a faint knocking sound from the engine after 3000 rpm after I accidentally kept it at the 8000 rpm red line on 4th gear for too long as I tried keeping up with the MFD and Apexi PFC commander read outs when doing a test run. My guess is bottom end damage. Please advice.

Dan.. I guess ur right about the Supra. Haven't gotten any head work done yet. The thought of dismantling that head worries me abit. As for the 600cc injectors, was looking for drop-in replacements by Nismo and that's the best I could get. The others were sard and tomei but needed modifications or new fuel rails which I didn't want to venture into at this time. Placed an order with greenline 2 weeks ago and still awaiting goodies to arrive. What kind of power should I expect with the setup I plan to run? Was hoping for something in the region of 600. The absence of dynos in this city make it difficult to makeout exact horsepower. But the fact that I manage to keep ahead of the Evos & Stis, I assume I should be in the region of 400

Guilt-Toy confirm what equipment I'll require for the distance tune and what you charge for it? Was thinking of purchasing the wideband O2 sensor kit from Innovate motorsport and the pfc datalogit. Suggestions anyone?

Thanks for the tip.. Trouble is living in Africa proves to be abit of a hassle when it comes to ordering aftermarket parts. Many ppl don't ship here. As for tuning experience, I have a tuning shop here and have produced fairly good results with evos & stis. Had a Supra RZ just before I got the GTR and that was a breeze to extract big power out of. The GTR seems to need alot more to make serious power.

Hi, Have the following ugrades: -K&N Induction -3 1/2" catback Exhaust -Apexi PFC D Jetro -GT2871R Turbos -Turbosmart Boost Controller (set to 1.2 bar) The power is not as good as I hoped it to be. Any advice? Have just purchased a Nismo fuel pump and 600cc Injectors hoping that'll make a difference. Also need help tuning the PFC since am running it on the base map. HELP!
