Hows it going everyone! I have joined here because I am the new owner of a 1994 R32 GTR Skyline here in the U.S. We don't have much if any support over here for Skylines anymore, so I have been gathering all my info and knowledge mainly from these forums, great use so far!

My main question right now is, how strong are these front and rear c.v axles? I have pulled the motor the other night, and I will be doing a full rebuild built for lot's of boost, are axles breaking a problem for GTR's? I'm looking for 700hp on 110 octane.

Here is a little shot of lasts nights work,

The whole drivetrain is pretty bloody good from the factory - only the most serious drag cars break anything except gearboxes.

But to be honest a genuine 700hp would put you in the "serious drag car" category so no guarantees

At the motor or at the wheels?

Well all the bushings are completely fubarred, the rear end clunks like no other lol. The engine had a severely blown headgasket. Was missing like 4 lower tranny bolts. Loose bolts and crappy just backyard style stuff done everywhere. Clutch slave wasn't bled. The body is flawlessly smooth though thumbsup.gif and paints decent.

I'm not too worried about it though, I will be putting my hands on pretty much every inch of this car. I really wanna use the r32 diffs with the v161 so I'm gunna flush all fluids and cross fingers, I have R34 diffs as spares.

I already have Energy Suspension Poly Euro Bushings to go all around the car. I have the V161 already too. Today I just ordered 87mm CP pistons and Manley connecting rods. Cosworth main/rod bearings with .001 extra clearance. ARP headstuds. I don't have main studs yet but will soon. I have a cometic gasket kit. I also ordered my PT6766h turbo today!banana.gif I'll be ordering cams and valve springs soon. I'm going to need a new water pump, and I'll also be using the Reimax oil pump, Greddy pan extension, 2-3qt Accusump system, and a bunch of other stuff. Once I get a few more things acquired I will be starting a build thread.

UPDATE!! Hey guys, no pics yet but only because the car isn't 100 percent done but it's somewhat close!

HERE IS MY ISSUE! Please drag racers chime in...

How many drag guys are exploding rear diffs? My fabricator wants me to do a Ford 8.8 IRS setup in my Skyline because I am trying to HOOK all 1000whp on slicks. He doesn't think the rear diff will hold up. So far I have DSS 1000hp axles, and an OS giken LSD back there...

I don't want to waste the money I spent on the DSS axles...but I also don't want to be replacing rear diffs all the time.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal 路 Posted

      Swapped the injectors around and the misfire followed. I went ahead and ordered the Deatschwerks 550cc injectors and am currently waiting for them to be ship and arrive. In the meantime, I've had my Nistune soldered to the ECU. Tested it, and and tried it out with the software. Everything should be prepared for when the injectors arrive.

      Yeah they charge a little extra for mods , last year I noted no mods but I did have an exhaust fitted after that so  better to let them know cause these kinds of things can cause the policy to be void if you ever need to claim.

      Rear subframe stay bracket bolt removal issues

      By DatsunBanana 路 Posted

      Thanks everyone for the replies and suggestions. Got the seats out (hoping I could find some existing grommets but no such luck). By tapping and measuring etc. I could figure out where I could drill through if needed. But first I borrowed an inspection camera and managed to go through factory holes in the chassis rail and could see that the captive nut was holding steady which is why it could retighten. So it was indeed a stripped section of thread, so I applied downforce by levering the bolt head with a screwdriver and went slowly back and forth until it came out. Camera helped a lot cos I could monitor that the captive nut was holding tight. Now I just have one very seized main subframe nut to tackle 馃槄

      Question about BoV on RB25DET NEO

      By Dose Pipe Sutututu 路 Posted

      BOVs do have a purpose, if you ever log pressure before and after the throttle body, you will see a spike pre throttle on lift off from a WOT condition. Enough to bend throttle blades / damage e-throttle motors or simple assist in blowing off cooler pipes. FWIW, the above on really applies to those running at least 2 bar of boost. OP shouldn't have an issue, on the other hand, here are some videos of my shit box over a decade ago with some succulent dose with the airbox on and off. That shit box is unrecognisable these days 馃珷
