Pulled the gearbox apart and what a mess! That's what 'clicking 3rd' with hot 295 AO50's will do to a 33 gearbox!  With some bits purchased from another donor box and help from Donny at For

Clean and up in the air. Final bits of work required to hit the track in November.

Wow. Yeah it has been a long time since an update in this thread. It's been laid up for a while. Sitting on stands and collecting dust. The last 2 years of my life has been a case of home renovation

So it's been a while since I've posted an update. That's because I've been so flat out! What a hectic month!

I'll go through the lead up first and then talk about WTAC and how massive the weekend was and how my mates/team helped me achieve a great result!

So PI as you may have read in Kory's write up didn't go to plan.

A faulty injector plug on cylinder 5 caused this...

The day after we had it pulled down and everything ready to go on Campbell's motor that he donated so I could get to WTAC.

We also noticed that the ASI ebay radiator wasn't handling the pressures of racing. Kinda a bit bent...

So we got a racepace spec radiator and so far it's great. temps have never been so low. It's crazy effective.

Johnny and matt ripped into the doors and all up took out 15kg, that's just steel! Glass on top of that!

All this weight reduction got the car down to 1249kg with no driver and no fuel. Not bad for a full caged car!

So the mad engineers bent me up a Gurney flap for the rear wing.

I think I'll leave it there for now. The WTAC story is a big one so I'll post that up at a later date.

That ASI radiator photo is exactly what flea-bay lovers need to see.

Good for a street car, not suitable for trackwork, reflected in the price.

I agree 90%

For most guys they are fine

But on a car like Russ'

Well the pictures speak 1000 words

Back on topic, how did you find the gurney flap Russ? Noticeable difference?

Love the build, though I'd be remaking the gurney lap if I were you. The height of the flap looks too large for the chord length of that wing. You'll be getting an inefficient level of drag associated with the extra down force the flap is creating. You should be looking at a gurney flap of around 5 -10mm in height.

Rad was fine for 1 year of track work. Got gradually worse. Seen them on other track cars so thought they'd hold up. No problems with cooling though, just construction. Looks like its deformed from high pressure. No head gasket issues, that's what we first thought haha.

Gurney flap and change of angle was very noticeable at turn 1 EC. The car felt way more stable and I think it may have had something to do with the final session being 1 sec quicker! The boot required re-packing after every session. By the end of saturday we had about 4-5 washers spacing it up! Need to do something more permanent now. Proper boot lid re-enforcement.

The gurney was actually mounted underneath the wing to begin with but spoke to an aero guy at WTAC and he recommended putting it above the wing so it sits higher as a result.

      Hi and best of luck with your car. Its a bit hard to tell how low the car is all round from that pic or if its been lowered or not. 90mm is a bit low on the front apron but it depends on the shocks & springs condition & whether or not its been lowered. Going to 19” wheels will give you 15-20mm depending on rubber but you might need new shocks. Mine -2005 are weeping fluid slightly but have lasted 19years!!. So if yours are original they need replacing anyway if they havent been touched before.

      Hi everyone, Recently got handed down a 2004 Skyline 350GT Coupe. I would like to change the wheels as the previous owner installed some weird ones. The current ones are 215/45ZR18, unsure of the offset, and sit pretty deep in. Would like to increase the ground clearance slightly as well as I need to get it roadworthy standard, currently sitting at 90mm. Was thinking that maybe I could kill 2 birds with 1 stone by getting new wheels.  Pictures of current wheels: https://imgur.com/bg1QMIu Any recommendations for the types of wheels I should be on the lookout for? Like the maximum and minimum offset, sidewall height, width, etc.  Sorry in advance if I'm noob, I do not know much about cars other than how to change the oil, a blown tyre and brakepads....

      Problem with 5th after manual swap on R32 GTS4

      By joshuaho96 · Posted

      Most likely your engine is toast, but also the R32 GTR has different ratios than the GTS4. In 5th it's basically the same, it's mostly 1st through 3rd that change. Stop trying to do WOT pulls before you make the engine entirely unsalvageable. Do a leakdown test and/or borescope the cylinders first. And a boost leak can overspeed a turbo. Make sure the turbo actually functions as intended.
