Project NashZilla: R32 GT-T NEO

[steveo1502]

So u figure out what was wrong with it? How much for the rb25? Can pm me, my next door neighbor just picked up an r33 but has an rb20 slapped in there,wierd, it's really rough,but the car is in excellent shape. he's lookin for a 25 , and in Calgary also, I'll give him the guys number for sure

I now have bad rod knock, didn't realize while driving that my oil temp was at 250 degrees Fahrenheit (its 190 during normal driving) and after that i had constant rod knock and my oil pressure was about 15psi lower then normal even after oil temps were cool again.

Sorry to hear.

Wow, so 121 degrees Celcius (250 degrees Farenheit). I think stock w30 oil starts to break down after 100 degrees Celcius and even w40 would struggle with a constant 121 degrees Celcius. w50 might work.

Average of 88 degrees Celcius (190 degrees Farenheit) sounds normal. Anything over 90 degrees Celcius is too high.

Nismo explains what happens to bearings here (might need to translate text) -

High oiltemps = oil breaks down, surface of bearing melts and clearances between crank, bearings widen = rod knock.

looks good man!
im toying with the idea of a 25 swap aswell, you should post up any challenges that you come across so i know what im getting myself into lol.

[amnash]

I've been slacking on keeping this updated. but the swap is all done. only thing I've left for the winter is the transmission wiring and the speedo. but i just wanted to have it on the road for the rest of the summer/fall.

had to buy an aftermarket drive shaft for the rb25(non neo) transmission.


here's what my kitchen floor looked like for a week while i was tackling the wiring. it sat there for a while why i did research and once i found little info on how to do the wiring with r34 loom i decided to just try and figure it out on my own. so with the rb20 pin out diagram and the r34 pin out diagram i just did one wire at a time. and labeled EVERYTHING.. i cant stress that enough lol
once i figured it out its actually pretty simple. just overwhelming at first.


here's a video of the first start up. (runs no problem once you have the fuel lines the right way around)

Nice man im sure your going to love that Neo.

[amnash]

looks so much better with a grill

[M13]

lookin' good. Ever find out what happened with your old motor?

Pump issue? clearance issue?

[amnash]

no i havent looked at it yet. i think a bearing went because i boiled the oil driving like an idiot

[G-E]

Where did you find the r34 cluster?

[amnash]

just on ebay. there's tones of them. there's a nice nismo one in the for sale section on this forum its BNIB

so i had an alignment done today and the car is handleing a lot better now and wheel isnt shaking like crazy. took it on an empty highway and had it at about 200 for a couple seconds, man this car is rock solid. so im happy with the alignment.

but.. after that good stretch down the highway i started to hear a noise under the hood and pulled over.
i then limped it all the way home not going over 2000rpm and its sitting in my garage now. ill be pulling apart a few things trying to find it. im hoping its a loose bold under the valve cover..

This is the last you will see of the rb20 on this thread. eventually it will be my new rb20 hard body project and i will make a new thread.

let these photos and videos be a reminder/warning for everyone to keep an eye on you're oil temps while driving hard. try not to be so trigger happy while breaking in an engine like i was either. It was conventional oil because i was still "breaking in" the engine and the oil lost all lubrication.

notice the pieces of bearing throughout the oil pan, on the cradle, and on the oil pick up.

some pics of the car all done. got a driving permit for the weekend so ill get some nice driving vids up soon too
