Hey guys, I've dug through some old threads but still trying to find a few questions left unanswered: - Does the 8cm version have any backpressure issues above 250rwkw? E.g. what backpressure/boost ratio is commonly found at 20psi+, is it less than 1.5:1? - Is the ramp rate of the 8cm version a lot more savage than the 10cm version? Which one would be faster off the mark? - In track conditions, does the 8cm version hold its own or does it get choked up top/end up with heat issues from being at high rpm.... - In terms of throttle response (e.g. driveability), which version is easier to drive? I drive my car mainly through the mountains and im starting to get regularly involved in track days, so I'm wondering which would be a better match for the car. Everyone seems to be telling me the 8cm coupled with HKS 256 cams is a match made in heaven for the S15, and the 10cm version will be a bit too laggy for a spirited street/track car... If i ended up porting the motor etc, would the 8cm still be a good match? Thanks in advance.
Hey guys, Since im spending most my time sitting on this site (instead of uni work lol) from now on thought id throw up my car and start a thread. Bought a shell about 3 months ago as a project and slowly started building it up over the next 2 months. This was my first proper build never having pulled an engine out before. I'll post more details of the build as soon as i have some more time. Plenty of blood, sweat, and tears pain haha really men dont cry, have been put into my new love. Makes me appreciate the car alot more building it up rather than buying one done, well worth the effort by the end and recommend others to give it a crack if you can then you'll know the feeling i have everytime you see it. Big thanks to some good mates who helped me along the way, my missus for putting up with my bitch'n when things didnt always work out and my bro for helping with costs when my broke student ass couldnt even afford bargain parts that popped up lol. Havn't chosen a name for it yet although the missus likes earnie, i like angry more dayummm those sexy BUT angry eyes Heres how it currently is Engine: S14 Black Top Tomei cams 256 Tomei rocker arm stoppers Tomei metal head gasket Tomei Z32 AFM Nismo 555cc injectors GReddy T518Z turbo (8cm) HPI stainless manifold Stainless dump Remapped ECU and loom (done in Japan) GTR fuel pump Utsumi 3 core 52mm copper radiator GReddy FMIC (painted black for stealth) Kakimoto 3" stainless straight through exhaust Driveline & Handling: NPC HD Organic clutch URAS Solid Shifter URAS Solid gearbox mount Nismo clutch slave cylinder R32 GTR Diff ABS delete R32 GTR brakes Drilled rotors GReddy Type S coilovers Cusco front strut bar Lenso D1R wheels 18x8.5" +35 (Kumho KU31 215/35) need spacers badly lol 18x10" +22 (Kumho KU31 235/35) Wish List: Taking donations Muffler (next week) GKTECH camber arms GKTECH toe arms GKTECH castor arms GKTECH engine fan GKTECH baffled sump GReddy Multi D/A gauge (Boost/oil pressure/water temperature) Luxury lip DMAX roof spoiler Recaro SR3 or R34 GTR seats (just some cheapish good quality seats that hug you more) Nistune Also gotta thank my parents for having my junk everywhere for 2 months, told them the build would only take about 2 weeks.. tops. haha yeah right
