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



after a few years i did general cosmetic stuff

18" mags, calais spats, lip spoiler, lowered, bonnet buldge etc


with the 20's



late 07 i decided it needed a freshen up, it took about 10 months from organising the parts, to gettin the motor back in the car - 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 its also turbocharged, turbo kit is stainles manifold, alloy intercooler piping, ebay turbo, turbosmart bov



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)







july of 08 i trailered it down to get a run in tune, we went very conservative running just 5psi.

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 made a custom gauge pod under the radio





after driving it for a bit i realised i was going to need some better brakes, so i purchased and installed a upgrade taken the fronts from 290mm sinlge piston to 330mm twin's and the rear from 275mm single's to 315mm single piston. i alos rolled the gaurds and threw in a adjustable panhard bar as i was having scrubbing issues with it being on ultralow springs


and some pics with the mags actually finally fitted for good











january this year the car just started flooding with fuel and fouling the plugs, the car was off the road for 5 weeks and i spent 700 bucks tryin to figure out what was wrong with it at another shop, decided to take it to 101 motorsport and it took rob 5 minutes to diagnose the map sensor was dead.

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


after driving it like this for a couple of months the exedy HD clutch started slipping hard, so after a call to NPC and telling them i didnt want a button as its daily driven we settled on a 10.5inch flywheel with HD clutch modified from a BA MK1 XR6-T and a ripshift

i thought all was sweet and then i noticed it started blowing black smoke, hooray, the turbo has blown a seal, so i figured i might as well step it up and i now have in my possession

Garrett GT35 with 82 rear
Turbosmart ultra 38 wastegatee
Turbosmart 800hp fuel reg
3.45 diff gears




so the car has been down at 101 motorsport for the last few weeks getting the gt35r fitted, along with other goodies


was down watchin it get dyno'd 2/5/09 and it has ended with mixed results

bad stuff
fuel pump and injectors are now to small -
wastegate is to small -

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
