Hi Guys, So I thought I'd start a build thread on the 2J conversion into my skyline incase any of you are interested. Im a fourth year apprentice mechanic at Toyota so sourcing genuine toyota parts for under trade price is handy. History: Bought a 1992 Nissan Skyline R32 Gtst in Christmas 2011 which already had an engine converson for a RB25. Was done a bit on the dodgy side so i spent the time and money fixing it all up to get it roadworthy and running the way it should. After having it registered for only a month I decided to take it to a drift track day up in Mackay to try it out. Had a ball the first few laps but then started smoking everywhere. Popped the bonnet and oil was spewing out of the PCV pipe fittings. Undid the oil cap with it running and the blow-by was rediclous... Took it home and compression tested it the next day to find cylinder 5 only had about 100 psi. Yet to pull the head off the engine to see what went wrong exactly but i suspect a cracked piston or chipped ring land. I looked into rebuilding the 25 or building up a 25/30 but they just werent quite what I wanted.
I have always admired supras and the reliability and the power potential of the 2JZ. So I decided im going to put a 2J into my 32
In the end I want a streetable daily that I can drive to work and back but will also take the abuse of weekend drifting events and constant limiter love during late night skids. So first I went off researching what I want in the engine part of the build. Wanting to make over 500hp, not to concerned about power figures cause every dyno is different, etc. As long as it is responsive enough for drifting and fun and games on the street. Being daily driven I want to leave it on pump gas BP98. But in order to make the most of the new GTX range of turbo chargers I want to give the tuner the potenial to tune for reasonably high boost. So I am looking at a meth injection kit to add too the setup down the track. Heres what I came up with: Some of this has already been put into play other parts have yet to be decided on and purchased. Head: Mildly ported head GSC S1 cams Titan Motorsports Adjustable Cam Pulleys Brian Crower Valve Springs and Retainers Genuine Valve Stem Seals - (Genuine Toyota full engine gasket kit including headgasket etc) Ferrea Valve Guides Ferrea 6000 Competion Valves - Std Size Block: Genuine Toyota Headgasket Genuine Toyota Oil Pump ARP Headstud Kit ARP Rod Bolt Kit ARP Mainstud Kit ACL Race Series Main Bearings ACL Race Series Rod Bearings ACL thrust washer set Hastings Piston Rings - Std Size Hot side: Yet to decide between a Garrett GTX3582R or a GTX3076R - either way it will get a T4 Twin Scroll 1.06 rear housing. MXP Custom T4 Twin Scroll manifold - Ceramic coated in black Aeroflow or DEI Titanium Turbo Blanket Turbosmart 50mm Pro-Gate wastegate Custom turbo oil and water lines. Custom Exhaust system - Thinking a Magnaflow cat and muffler Intake: Standard intake manifold Standard throttle body modified to delete traction control butteryfly Fuel system: Standard fuel rail with 6AN fitting tapped into fuel pressure reg port 8AN braided stainlesss steel fuel feed lines 6AN braided stainless steel return lines Nippon Denso 800cc Injectors Aeromotive A1000 FPR Bosch 044 Fuel Pump Custom alloy under car surge tank - or just an in boot setup seeing as you cant buy an off the shelf under car tank for an r32 that I know of Walbro intank lift pump Driveline: R154 gearbox - remote shifter type Custom tailshaft NPC 5 puk sprung center carbotic button twin plate clutch NPC hydraulic throw out bearing Light weight billet steel flywheel
As part of this conversion I will be prettying up the engine bay by doing a wire tuck, moving the battery to the boot, moving the washer bottle to the boot, hiden coolant bottle, respray the engine bay and removing alot of unneccessary brackets off the vehicle. Looking at using a Haltech PS2000 ECU with fully terminated harness, boost solenoid, Wideband sensor, and EGT sensor. Standard coil packs are looking at bit sad so they will most likely get replaced with either genuine standard items again or MOJO LS2 2JZ coil packs. List of mods the car already has: Crossmember cut and shut to move steering rack forward, R33 front brakes, Steering rack-end spacers, Hardrace adjustable rear camber arms, Rear subframe collars, Modified bumps stops - ground to near nothing. Other bit and bobs I would like to get as part of the build: 52mm Koyo or PWR alloy radiator, AU falcon thermo fans or Spal fans or similar (will be controlled by the Haltech), Tein super street coilovers, Cusco front strut brace, Ultraracing one peice rear strut brace, Slotted rotors and some decent brake pads all round. Would like to get the knuckles modified to make use of the steering rack being moved forward. Will track down a S13 Non Hicas or R32 GTR rear swaybar. Considering removing rear seats and adding a half cage. Wheels currently on the car are Lenso D1R's Fronts - 18 x 9 +32 wrapped in a 225/40R18 Federal 595 SS. Looking to go up to a +15 offset in these wheels due to currently touching chassis rails at full lock. Rears - 18 x 10 +22 wrapped in a 235/40R18 of the cheapest tyre I could buy at the time cause they just dont last however with this new found power I wont be cheaping out. Will spend the money on a decent set of tyres. Probably semi slicks.
Here is a photo of the 32 and the aristo half cut side by side on a typical sunday. Had the fuel tank out of the 32 cause I was using it to run the half cut to make sure it was all good before pulling it apart.
Will upload more photos within the next few days
