May 2010- Got spoiler, adm reflectors removed and added the rear pods :)

Before:




After:







August - October 2010

Got a little bit bord with the power and wanted more so we decided to go with a new setup.

- Garret GT3071 .64 (4"mouth)
- Stock Manifold modified for a external wastegate flange
- Tial 44mm External Wastegate with a 11psi spring
- Tomei 256 poncams
- Rochester 750cc Injectors
- Gktech RAS
- Walbro 500hp fuel pump

- Mircotec ecu (no more afm)

Power 258rwkw @ 16-17psi

1/4 mile: 13.011 @ 113mph 2.2 60ft. street tyres -.-




Then i bought some Work Emotion XD9 Wheels : 18x9 + 30 18x10+30










After 55,000kms with the mods and everyday thrashing the motor started to knock.

The motor was missing about 300-400mils of oil :( i still kick myself everyday for not checking
the oil

btw ye it was still my daily until it started knocking so i then bought a little civic for a cheap run around :)

So we pulled the motor out to see what let go.





After we pulled the motor apart we were completely missing a bottom end bearing from piston 4.
Could just see little shavings in the oil.

Look at the piston positions :\




Wasnt sure if i should just put in another stock motor and keep the same setup or sell the
setup and rebuild it all out or maybe just throw in a rb26? I also thought of a SR20VET
setup but i was looking at another 6k on top :( maybe next rebuild :p

I decided to rebuild the sr and go all out so i sold my gt3071 with manifold and 44mm gate,
cams, and the avcr for $2100 to a mate and started saving for the rebuild.

- Nitto 2.2L stroker kit (Pistons, Rings, Crank, H Beam Rods)
- Nitto Head Gasket with ARP Head studs and main studs
- Solid Head Kit with custom cam specs and 1mm oversized valves, head work
- Garrett GTX3076 .64
- 6Boost Top Mount Manifold ( HPC Coated )
- TurboSmart 50mm Progate
- TurboSmart Duel Stage Boost Controller (mechanical)
- Greddy Intake Plenum
- Tomei Sump
- New oil pump and timing chain
- Custom Intercooler Piping
- Bottom End fully blue printed, Torque Honed/ balanced.etc
- Sent Mircotec away to get a 3 Bar mapsensor done
- Reinhard Stainless steel catback with Xforce Varex Cannon
- Custom dump pipe

When we sent the block away for machining and they acid washed it, they noticed
there was damage in Cylinder 4 and could not be used for a high boost application.

Then i swapped over the block for a good condition one + cash adjustment

Future upgrades:

- SR->RB gearbox conversion
- R33 gtst series 2 turbo gearbox ( looking for one )
- GTR rear end with 1.5way diff
- E85
- Coilovers ( maybe bc or teins)








I wanted to change the look of the car and i sold the XD9s to a mate and bought these:

Work Meisters s1 3piece (white centers)
Front: 18x9 + 22
Rears: 18x10+18

I wanted to try something different instead of doing the typical black centered meisters :)

If i dont like the white centers once the motor is in, ride height + camber adjusted, gaurds
lipped/slighty pulled, looks like ill be getting the centers sprayed black.








Also bought:
ISC:
- Camber tops (front)
- Rear Camber Arms
- Rear Toe
- Front Castor Rod
- Front tie ends

Suspension: Stock struts with aftermarket compressed springs for the moment.

Motor should be built by the end of July. Currently at Machining shop in nsw.

Thanks for reading,

I'll keep you guys updated :)

Nice, motor, reads similar to mine, engine wise through the various stages I've been so far, with very similar terminal speeds and 1/4 mile times. I'm suprised your box has lasted though, as mine let go quite spectacularly a week after I'd taken the car up the strip.

You are lucky :D

I knew I was running into problems as I couldn't get the car into first or reverse after my 1/4 mile times. I didn't particularly abuse it off the line either, as I could have been a lot more aggressive but wasn't to try and save the box :wack:. Mind you I had at a good guess another 100kg in the boot with camping gear, crates of alcohol and a suitcase filled with the other halfs nonesence, which resulted in my fastest and highest terminal speed 1/4 to date, lol.

Haha well the more traction you got the more stress you put on your drivetrain..

When i ran the first time with 202rwkw it wasnt bad but when i put the new setup
In i was wheelspinning still in 3rd gear lol hence the crap 60ft :p wheelspin
saves the gearbox and i guess prob saved mine aswell lol. With the new setup
i want to run semi slicks so i wont even bother with the s15 box. Might go a 33gtst box :)
