GD V2 – Part 22

May 15, 2016


The final preparations are being carried out on the car before I can give it a test drive, so in the meantime I thought I would highlight all the engine specs and parts for those interested (parts not mentioned are OE, and I’m sure I’ve missed things):

Bottom-End:
ACL Race crank bearings
ACL Race big-end bearings
Apex Performance conrods
Wossner 86.5mm 8:1 pistons

Top-End:
Tomei 256 Poncams intake and exhaust
Custom rocker shims
Cometic 1.1mm head gasket
Apex Performance rocker arm stoppers

Intake:
Front mount intercooler with custom piping
Apexi Power Intake filter

Exhaust:
Garrett GT2871R turbo 0.64AR
XS Power tubular manifold
Japspeed downpipe
3.5″ catback with decat

Fuel:
Walbro 255 fuel pump
Nismo 740cc (JECS) injectors
AEM fuel pressure regulator

Cooling/Fluids:
Billet oil sandwich plate
Thermostatic oil filter relocation block
Mocal oil cooler
Driftworks Supercool alu radiator

Ancillaries:
Apex Performance alu pulley kit
ACT Performance clutch kit
AH Fabrications oil catch tank
Apex Performance short shifter

After the mapping session I also checked the valve clearances again as everything has bedded in a bit and should have settled. Unfortunately the clearances are a bit higher than I would like which explains the elevated valvetrain noise, and will no doubt cause accelerated wear on the cams. Valvetrain is something that I have limited experience with and have a lot to learn; I assumed that the clearances would close up a bit after the valves have set in their seats but instead the clearances opened up a bit which means other parts have settled.

Also, I had to change the fuel pressure regulator to an AEM unit, as the “Aeromotive” unit started leaking. It was probably some Chinese knock-off unit, despite it not being that cheap. The good thing is that AEM unit is much smaller and nicer.
