hey thought i'd show you guys my car, and the work i've done to it since i've had it this is what it looked like when i purchased back in 2003 these days so for the last 10 months or so i have been building a motor for it heres the specs the motor is fully rebuilt and dynamically balanced with an acl race series rebuild kit has all crow valve and timing gear ( valve springs, retainers, lifters, 2mm longer pushrods, timing chain, valves) tighe 1081 cam (nice and big they say) new genuine crankshaft ported heads and inlet v8 throttle body 32lb fpv injectors 2 bar map sensor msd coils custom made 10mm topgun leads as coil packs are relocated walbro gss341 pump Haltech E6GMX and some dress up stuff to make it good Exhaust 3" high flow cat and 3" lukey with 1 muffer and 1 resonator and i converted it to manual the manual conversion was purchased from the wreckers and then the box dropped off to gear torque for a full rebuild and to get the gears cryogenically treated. tailshaft has been rebalanced and has all new centre bearing and uni's here is a few pics of the change over and the final result (coils moved, fuel reg installed and generally neated up since these pics) so far the car is on run in and as such im babying it and only running 5 PSI, pretty boring. at 5PSI it made 240rwhp and 598Ftlb of torque interior i've got saas racing seats and a saas sports wheel, sterio is below average but meh i've also mad a custom gauge pod under the radio well managed to get a few things done in the past few weeks, fitted the front upgrade kit, and rolled the guards on the back so now got the 20's all over and i made myself a sexy little intake pipe front wheels with new 330mm rotors and twin piston calipers my new intake pipe and some pics with the mags actually finally fitted for good Some original photos have not been recovered yet.

so, after being off the road for 5 weeks and spending 700 bucks tryin to figure out what was wrong with it it took rob 5 minutes to diagnose the map sensor was dead. so i got a 3 bar motec map sensor, thanks to 101 ! dyno'd the car as it was and made 240, same as at other place. rob then just actually fixed up the tune because timing had been set at 17 degress from 0-5100 (where they had the limiter) that was fixed and limiter moved to 6000 re-dyno made 270hp on 5psi i was pretty happy with that so i put my new spring in the wastegate that i thought was a 14psi, he started dynoing, got to 2500rpm and it was already at 18psi and making 175hp at the wheels, bit dangerous for the motor, so back in went the old spring and we decided to just bleed it off ok. so re-dyno again from 2600rpm to 4400rpm the car ran 10psi at which point it steadily decreased to 7.5psi at 6000rpm exh housing building up to much pressure and the spring cant hold it anyway the car ended up making 306.4rwhp which is damn good, considering it did that with about 8.5psi at that time unfortunately my video camera was flat, and my phones camera is fked, so no video's guys all i got is the dyno Some original photos have not been recovered yet.

That turbo did heaps better than I thought it would. Only dies in the last bit of the graph. 35/40 and a .86 rear would be a real weapon. Should be able to run more timing and less fuel with that turbo as well. You could see another 50hp no worries taking it nice and easy. Awesome job

just picked myself up a turbosmart ultra38 wastegate next on the list is a turbosmart 800hp fuel reg, and a garrett gt37 with a 82 rear, (fair bit cheaper then the 35r seeing its only journal bearing) then a retune with 12 psi and see if i cant get some better results

well, the gt35r has been fitted, along with an new turbosmart fuel reg and wastegate - (thanks ash for the prices) was down watchin it get dyno'd today and it has ended with mixed results bad stuff fuel pump and injectors are now to small - gettin a big bosch external and some 42lb or bigger injectors wastegate is to small - upgrading to a 50mm so with a 7psi spring in the gate still crept up to 11psi and she made 352.9rwhp at 5200rpm before it was way to lean to continue so rob has put in a boost cut at 8psi which kicks in around 3500rpm until we upgrade everything else heres the dyno new pics with the gt35 well i got myself some new valve covers, gettin rid of the kilkenny ones cause we cant stop them from leaking, got some s1 VN alloy ones, and have polished them up and weled in some fitting for a catch can Some original photos have not been recovered yet.

PROGRESS... well i finally got around to relocating the battery to the boot. ran 70mm2 (bit bigger then 0 gauge) cable from the battery to a distribtion block and put everything that used to be on the battery onto that, and its protected by a 200AMP fuse. i ran it under the car in 20mm electrical conduit then went up the firewall and up into the boot in coro. so now i can finally make my new 4" intake and box it up spot for air filter 4" alloy pipe and new filter battery in the boot i also got my new wastegate setup welded up running the 2 38mm turbosmart gates ash got me, and there even plumbed back (no more open gate salutes :cwy: ) and i've got myself an alloy radiator dual core, way thicker then the old one, im getting some stainless radiator hoses made up so i wont put it in till they r done Some original photos have not been recovered yet.
