HI looks like misfire sparks under boost. have same trabble /sort out replacement iridium spark plug and readjust gap.secont e manage not adjust timing maybe neded set up 10-13 deg .

some new info:Dhttp://www.clublexus.com/forums/sc-400-300/492459-2jzge-na-t-tt-ecu-mod.html

nice one:idea: bike kit car supra haha thats evolutions

hi mains run like this 2 single wire o2 sensor 1 use for afr sensor and 2 connect ecu

hey fly:Dbefore after

Top and bottom of it is TT pistons and TT headgasket combo have been tried and tested a few times and because of it resulting in a lower compression than a stock TT and with it also affecting squish! It's apparanty too slugish off boost. TT pistons - GE head gasket is good for 500bhp on pump fuel TT head gasket - GE pistons is good for 500bhp on pump fuel So if we are wanting a good responsive 600bhp NA-t we need somthing along the lines of TT pistons and a headgasket inbetween the stock thickness of the GE and TT. I'm thinking around 0.9-1mm of thinkness. ? best way tt piston gte hg 1.3mill but take off 2 multilayer :1.0mill best compromise

GE combustion chamber (head, gasket, piston) 55.5cc + GTE head gasket extra 6.04cc Gives .085”(2.15mm) squish = 61.54cc = 9.12: 1 GE combustion chamber (head, gasket, piston ) 55.5cc + GTE piston extra 6.7cc Gives std GE squish .045"(1.14mm) = 62.2cc = 9.03: 1 GTE combustion chamber (head, gasket, piston) 66.6cc + GE piston minus 6.7cc Gives std GTE squish .055"(1.4mm) = 59.9cc = 9.34: 1 Great picture and measurement explain all questions.well done:notworthy

If you have a stock non-VVTI NA then your stock compression is 10:1. Installing a stock TT HG will bring compression down to a boost friendly 9.2:1 which is ideal for running 17psi on almost any T4 turbo! TT HG and TT pistons will bring you down to 8.5:1 compression which is identical to stock TT compression! Non-VVTI 2JZ-GE blocks are identical to TT blocks with the exception of oil squirters in the TTs and lower compression hiper-pneumatic pistons, (NAs have cast pistons!) I've personally installed a Eristic 1.3mm TT (stock TT) head gasket on a 3.4 stroker running a GT4788 turbo and it held fine under 38 psi of boost and the car went 8.38 @172 without spray! You can get one on ebay for like $40 shipped! Stock NA headgasket - 0.5mm (10:1 compression good for 11-12 psi on 93 octane) Stock TT headgasket - 1.3mm (9.2:1 compression good for 17-18 psi on 93 octane) BoostLogic NA-T headgasket 2.5mm (8.5:1 compression good for 32-34 psi on 116 octane) HKS TT headgaskets - 1.3mm, 1.6mm, 2.0mm, 2.5mm, 3.0mm

well,software exist for calculating compression /boost.high compression quick reaction with low boost of 0.5bar after start detonation.your target 600hp definitly needs low compression piston for more boost 1.3bar maybe 1.5bar.one turbo 61ar smooth and quick reaction.sorry my English google translate. If you have high compression you have a high chance that the head gasket or head blow.after I find some pictures from my destroyed head 2.0bar:innocent:

:Dhi first setup* 2.0mill steel head gasket,550ccm denso inj,clutch ceramic stage 4,turbo t4 70 ar,ecu aem ems v2 bost 0.8-430hp,1.0-478hp,1.1-507hp.I'm tested more boost max 2.0bar but engine dies high temp and compression.now gte piston,gte head gasket 1.3mil,strong oil pump ,gte engine wire loom+blitz ecu.will be done next mont if everithing ok;)

hi im currently running over 1 years with na-t ,build self last year 507hp back wheel.now engine out from car and everything check and done some different mod:D

two parts lower and uper intake

very nice picture vs background:cool:

Good luck , looking forward to the updates***interesting project:notworthy

im go again like it steik jumy jumy:innocent:

Hi first time i have been to a meeting and I really enjoyed it everyone was being friendly:meeting: and looking forward for the next metting.
