My 1995 GTR project thread.

[cortexx]

Glad some of my project details helped you out there

Im actually in the process of collecting the parts i need to keep me busy over the winter. Finally got my hands on a new Nismo collector , thanks to daryl at right drive for sourcing that for me , daryl was also the cheapest price for it too .

The stock fan and shroud is being junked in favour of an electric fan mounted on an aluminum shroud i am in the process of fabbing, Also looking to lose some power drain on the front of the engine with a different set of pulleys . doing some research on a single piece duralumin rear propshaft to get rid of the 2 piece , and a lightened flywheel. Transmission has to come out for a rebuild as the synchros are shite . Mods to the car are favouring response over power now. weight loss on the drive train is desirable.

Longterm i'm looking for an ARC airbox for a decent price and a set of nismo MAFS .

Here is a pic of the parts pile so far



and as closeup of the nismo plenum .

Damn! I wish I had your budget! Coming along very nicely, I'm jealous ;-)

[gtrjon]

damn dude must be nice! im still ballin on a budget

[GodZillaa]

faurrkkk, thats beautiful, your gtr and the parts! great work!

[cortexx]

It's definately a work in progress but thanks anyways

[ChezoGTR]

that plenum is damn beautiful. i want

[EMAGDNIM]

Classy baller parts like always! I love it!

Update:-

Well i have been experimenting with different fluids in the transmission - the car had some dodgey synchros for 2nd and 4th (not too bad but crunched if you tried to shift too fast ) since i got it .

I originally drained the oil that rightdrive had used (not sure what it was) and filled it with royal purple max gear . That was 2 weeks ago and the tranny was alot worse for synchro crunching. I figured it was inevitable that a tranny refresh was in the near future.

Last night i drained the royal purple max gear and refilled it with Redline heavy shockproof gear oil . The difference is amazing , very slightly stiffer when cold but after about 10klm the thing shifts like butter .

After about 40 klm last night the redline has proved it self , i can pretty much run up and down the gears as fast as i like , its like a different beast , no crunching at all .

I did some reaearch on the product last night and it seems that although the oil is very thick , it has a low friction coeficient so it does not create unecessary drag on the synchros while cushioning the gears and bearings themselves. Pretty neat Going to fill my front diff with it tonight , too bad i cant use it in the rear diff.

thats great news

Redline FTW!

[ColinR33]

Filled mine with Redline last year, lovely stuff, glad it worked for you too!

[cortexx]

and the colour .... i could almost drink it , strawberry falvour anyone ? lol

Redline is awesome oil. In all honestly, all my experiences with Royal purple has been sh!t.
I seriously dont like that stuff, all of it, engine oil, tranny oil, etc etc.
For me its Castrol Edge In the engine, Redline in the Tranny, Motul RBF in for brakes, and Prestone Non mixed for coolant!
This thread requires MOAR PICS!

Non-Mixed coolant??? That would be Highly acidic and rot your block?

And has far less favorable thermal properties than water... If you were going for high performance, I'd go pure water, water wetter and an over-pressured system (1.3bar rad cap, etc) but that's my engineering POV. Seriously though you need to mix some water in if you don't want sludge, stat.

Edit: I have RP in my tranny and I still have to play with my second gear so that it doesn't crunch. I'll eventually try Redline.

Ever got mistfull of Rust Check in your mouth? Smells and tastes like cherry. BTW, don't use a spray outside when you're facing against the wind.

Edit Edit Edit: Fuuuuuuuuuuuuuuuuuuuu looking at your fabbing and parts I wish I had a job, a garage and a liiiiiiiiife

The coolant should consist of 50% water and 50% antifreeze , antifreeze by itself is not an effective coolant , it's basically a lubicant.
When you mix antifreeze and water you end up with a very fine suspension of water droplets in the antifreeze.

When the temp drops below freezing the water droplets still freeze but it retains an apparent liquid consistancy due to to size of the frozen droplets. If you were to look at coolant at -10 deg c under a microscope you would see microscopic frozen water droplets. The Ethyl glycol is just medium they can exist in and slide past each other to retain liquid like properties.

I remember checking this a while back and i'm pretty sure the water holds about 90% of the heat and the ethyl glycol holds around 10% of the heat in a 50/50 solution. The water wetter alters this to about 95% water 5% ethyl glycol.

And you would expect just water to be the best coolant - but you need a lubricant in the system to lube the water pump or it will leak. Antifreeze also contains corrosion inhibitors .
