1989 nissan skyline r32 gtst

[VinnyZ]

Hello everyone, I have a r32 gtst original rb20. I picked up about a month ago. It has 185000, what are usual problems that I should look out for, it runs 5-7 lbs of boost I think there might be a leak. Also the intercooler fan has cracks. Car runs & drives really good otherwise.

Stock boost level is around 7-8psi. Check for a blocked cat, faulty internal wastegate actuator or the leak you mentioned.

If looking at stock boost gauge, that's in mmhg and has to be converted to psi. Max on that boost gauge is around 13.5psi (+7 mmhg).

There's many. As long as it's serviced correctly you shouldn't run into many problems (just like any car you buy).

Usually engine requires refreshing every 100,000km and that involves replacing ignition system (coilpacks, coilpack loom, ignitor / ignition module), injector loom, spark plugs, rebuilding auxilaries, etc. Also the usual refresh of the engine with new rings, reseating valve seats, fitting a aftermarket oil pump drive collar (once only), etc.

Then there's things like wheel bearings, bushes, replacing or rebuilding driveshaft's, rebuilding gearbox, rebuilding diff head, etc.

He did ask.

Most of parts probably would have been replaced already as part of routine servicing.

Didnt kill anything for me actually... the car is golden then, there is no leak cause it is in mmhg. I replaced the spark plugs recently & rebuilt the tranny. Took it to my mechanic and he sailys the car is safe & sound. Ordering a new moshimoto rad & rad fan cause the oem rad fan is cracked between every spline. Thanks again Skym!

You're welcome.

How to convert mmhg to psi:

51.71487786825 mmhg = 1psi

It should have "x100 mmhg" in the lower right corner of stock boost gauge.

So

5 x 100 = 500 mmhg

500 mmhg / 51.71487786825 mmhg = 9.6683975793931367504153401825142 psi

7x 100 = 700 mmhg

700 mmhg / 51.71487786825 mmhg = 13.53575661115039145058147625552 psi

Most upgrade to an aftermarket boost gauge when exceeding 13.5psi.

Make sure engine isn't running too lean on a dyno, as anything above 12psi is bit high without a FMIC, ECU tune, at least a fuel pump upgrade to suit (not enough fuel with stock fuel system, stock tune).
