I guess I should do a build thread. I've never really gotten round to it. Bought the car a bit under 2 years ago and did the usual FMIC, exhaust, nistune etc and wheels and suspension. Enjoyed that for a few months (made around 210kw on e85 with stock turbo) and then started losing stupid amounts of coolant. Head is lifting... yay. Bought a new head gasket, ARP studs, HKS cams and prepared to redo the head. As the parts arrived I decided I should just do a simple VE conversion and slowly improve it as I went... that wasn't going to happen. Long story short, I did v1 of the conversion with a stock bottom end and td06. Eventually all the valve stem seals stopped being effective and I lost compression in cyl 3 - there was a healthy chunk missing between the ringlands, but no damage to the bore. Then came V2 of the conversion. The aim was a very responsive street/track car. Specs of the V2 motor; Block; - s15 block - 87mm CP 9:1 VE pistons (making around 9.5:1 compression with thinner HG) - Spool imports rods (aussie company) - stock crank, ACL bearings, ARP mains, Cometic 1mm HG Head; - p11 SR20ve head with stock cams - new guides and seals - BC springs - a bit of porting and polising (cleaning up casting marks etc) - p12 cam solenoid Other stuff; - Borg Warner EFR 7163 t4 twin scroll with a TS full race manifold - Mazworx v2 intake manifold (original one cracked everywhere and was replaced) - Bosch 2200cc injectors, Turbosmart FPR1200 FPR, Walbro 450LPH e85 pump - Adaptronic plugin ECU and Race tech dash 3 - Ls2 truck coils - Z32 gearbox with a NPC ceramic button clutch - will hold 600WHP but feels very very nice to drive - 4.36 diff - MCA blue series coilovers Started as this; Now looks like this VE motor fresh from NZ V1 head setup - p12 CAS and taarks relocation stuff Taarks stuff VCT Drain Block. VVL head feed also blocked V1 as it ran for a couple of months before losing compression, seemingly due to degrading valve stem seals Cracks in the old Mazworx manifold Old Vs new. Different design and support structures/radiused edges Close up of the improvements Piston 3 - Bore had no damage to it! Filthy CCs. Lots of oil Doing a bit of smoothing. There's a nasty ledge on the backside of the valve. Apparently removing this should help Bored and honed to 87mm and decked with VE oil pump 87mm 9:1 Comp CP pistons courtesy Defsport Full race exhaust manifold supporting the super awesome t4 twin scroll EFR 7163. I'll be using the boost control solenoid, standard actuator (will get a high boost canister) and included compressor recirc valve. Clean Head Motor done and ready to go in. You can see the p12 solenoid mounted here with the oilfeed supplied directly to the solenoid block In and ready to start! About 500km into the run in now and so far it feels absolutely great to drive! It honestly feels the same if not better down low than my original setup with DET/t28 and I have barely any timing at the moment and only running a medium canister with no boost control assistance. It'll always be run on e85 so i'll be able to push it quite hard and it seems like it'll do 370rwkw/500WHP and rev over 8000rpm. I'll be seariously impressed by this, especially since it feels so great down low.
