Suspension: King springs front, cut stock rear springs with rubber spacers for stiffer coils, 2 stock rear ET swaybars, stock N/A Pulsar front swaybar. 30mm longer rear studs, 6mm spacer on rear.
Performance: This is going to be very dependant on a what stage mods were at, using my G-tech (around 3thenths and 6% optimistic on speed) on the same stretch of road.
'Bought the car dead stock bar a 2.5inch exhaust. Soon blew my first head gasket as the waste gate actuator was getting stuck closed resulting in too much boost. Bought a G-tech not long into the ownership of the car. Ran 0-100’s in flat 9’s ¼’s in high 15’s. Upped boost to 12-14psi, dropped 1sec off the 0-100 and ½.sec of the ¼ mile. Hole sawed the standard T/B to take a hand fabricated 53mm butterfly + relocated AFM at the same time. This netted in a big increase in throttle response. Installed 4 puck Brass button clutch. 0-100 in 7’s high 14 ¼.mile Burnt an exhaust valve/blew head gasket, swapped heads with a spare I had out of a burnt wreck, slightly ported the head. Big mistake using burnt head!! Bent three exhaust valve due to valve bounce of the softened valve springs due to the car being burnt and creating massive heat in the engine bay. Swapped exhaust valves. Installed small I/C, more boost 15-18psi. Car running high 6’s 0-100 and mid 14’s ¼.mile. Removed all unnecessary weight. Best of low 6 0-100 and 14.26 ¼.mile. Swapped to L20 T3 (wasn't actualy a L20 turbo), and Supra I/C and 3inch dump, traction posing a huge prob, easy low 6’s and 14’s. Went to Eastern Creek with some slicks, engine running bad ran 14.559 @ 154kmh, massive lean outs due to stuffed FPR. Found problem, upped pressure, ran 13.73 on the street with slicks. Engine died due to lean mixtures at the track, busted piston rings. Re-build, did more porting, more boost 18-20psi, run high 5’s and high 13’s on street tyres. Broke ring-lands off a piston due to lean-out detonation. New pistons AGAIN. Installed O2 sensor + metre, installed VL helper pump, installed malpassi RR FPR, installed big I/C and full 3inch system. Wound up fuel pressure, mixtures o.k. Ran 13.71 @ 161kmh at the Creek. G-tech shows 0-100 in 5.31sec 13.31@173kmh. Achieved goal of running sub 14sec ¼. @ 100mph+ with standard ECU + injectors + AFM.'
(Lifted straight from N12 Editors cars)
Since then (2001), installed Autronic, broke the turbo when part of a bolt smashed exhaust wheel, swapped to VG30DET T3, dramas with boost surge (too much boost, not enough flow), boost upped to around 23psi. Still high 5's/high 13's but speed increase to high 170's. More tinkering.
At this stage in 2005 I finaly got it on the dyno for the first time at a dyno day. Spat out 155kw on 20-22psi.
Around now I took it to the Creek, and due to stuffing around with things the night before, I couldn't get more than 12-13psi out of it on the evening, it ran something like a 14.1 @ 97mph, I had left one of the hose clamps loose on the I/C plumbing!!!
January 07, made 3mm phenolic inlet manifold spacer, made 3 step adjustable cam sproket, installed reground cam, swapped over to RB25/VG30 turbo, a little more boost. G-tech low/mid 13's on track tyres at low 180's terminal speed. Dyno tune on mates dyno, 175kw 24psi (100 octane Vpower July) 450cc injectors 90% duty cycle!
Increase base pressure to 50psi, theoreticly flow increased to 520cc, retune 179kw 24psi (98 octane Vortex) and 191kw 29-30psi (Vortex with 15% toluene). Max power made before 6000rpm and falling quite quickly. October.
Intended to go to the track, but the meet was cancelled due to wind!
I need to get some G-tech results with the latest config which hasn't changed much since then.
As of 16/07/08 13.1 @ 109.75mph (12.96 @ 185kmh G-tech)
[/b]Future mods:
Fabricated manifolds and a turbo designed to run 30psi. Run a flat 12 and crack the biggest chubbi known to man!
Breakages:
At least 8 blown head gaskets, 2 sets of bent exhaust valves (from missing gear changes and popping out of 5th under load), 3 3rd gear synchro hubs, broken ringlands off at least 8 pistons (most due to detonation, a couple from piston/valve episodes), burnt out fuel pump from running out of fuel and driving the car on the starter ,stuffed fuel pressure reg, busted turbo from shrapnel going through it, around 6 standard spark plugs all from cylinder #4 until installed NGK Iridium's, gone through 2 crank sprokets due to harmonic balancer coming loose.
Oh yeah, and 2 cracked blocks.
There is more, but I can't quite place individual events.
