Im gana pull the RB25DET out of my R33 no 1 cylinder is down to 90psi and i have bought a new motor at the right price.

U can see the motor running in the next week or 2 if u are interested in buying it.

The motor has done 92,000km may only have a blown head gasket.

Im after $1000

pm me for more info

sorry my bad

Its a long motor all the manifolds are being used on the new motor may come with the coils have to see whats on the motor when it gets here in the morning will let u know but at the moment its a bare long motor

The car was put upto 16 psi and now it gone down to 90psi so it may be the headgasket but i have a worked motor to put in that i got at the right price so im not gana bother with it.

i know they sell for more but im after a quick sale there isnt any oil in the water and the oil is cream so yeah hard to say. But it is still running in the car on low boost runs sweet still so it can be seen running in the car in newy if sombody is keen cheers

dont talk shit, it wouldn't be the head gasket if only one cylinder has low comp. its not a bigg daddy truck where each cylinder has its own head gasket haha

1 wat to find out what it is pull the head off could be a burnt valve leaking valve could be anything but all i know is its still running fine in the car

of course it's possible,each cylinder has a round ring that seals the two mated surfaces(head to block),if you break the integrity of the ring it allows leakage of compression on that cylinder....the other sealed cylinders are unnaffected.(this i know from experience by the way)

it is possible that the piston ring may be cracked,you can exclude this by squirting some oil in the spark plug hole and immediately doing a compression test,if the compression goes up the chances are it's a piston/ring problem

it is possible that the compression is leaking into the water jacket via the headgasket,would get worse with more boost,may show up by overheating,pressurising the cooling system,rough idle on start up first thing in the morning(water leaks into the cylinder overnight and fouls the plug)

if it's a small leak it is unlikely to account for a big drop in compression,best way is to test it with an S-TEK tester that is very sensitive to carbon monoxide in the coolant(even if there are no symptoms),costs about $80 from auto parts store eg coventrys

if its a burnt valve you may hear it popping from the exhaust on heavy decelleration

obviously head off is the best diagnostic route,but the above would take less than 1/2 hour to perform and give some indication of the problem

good luck with the sale

    • All I can say Duncan is good luck and I hope that Neil did not run any E85 in Cheryl. I have recently experienced the full spectrum of fuel tank issues in my R33's that had been caused by E85 and contaminated fuel. When you take the cover off the top of the tank and have a look inside you will get an understanding of how easy it will be. Best case situation is clean fuel with minimal contamination. My GTR was like this and it was a very simple operation to just grab the fuel pump carrier bracket and slide it up and out of the tank. My three GTS_T's had different levels of fuel contamination that was probably caused by E85 in the fuel.  In the worst case all of the metal components in the tank had rusted to the point where there were pieces of rusted metal swirling around in the tank. This required the removal of the exhaust, the tailshaft, the complete rear cradle and the fuel tank. The components in the tank were that rusted that it took days to get the fuel pump carrier and the mounting brackets out of the tank. When the tank was finally cleaned, everything inside the tank had to be replaced. With the tank all back together I could then reinstall it in the car along with everything else that had to come out. Good luck and I hope that you find a clean tank.    
    • It is a two door. It is black and also still has the OEM wheels and stereo. Exact model would be KR_R32RGFEL_SS According to GTR-Registry.com is a 2 Door Coupe; RB20DE; 2WD no HICAS; MT.F5; (11L) Projector Headlamps and Fog Lights; (12_) Electronic Active Full Auto Air Con (Climate Control); (13-14SS) V Selection -- Which seems to be accurate description of my variant. Will try to upload a few pictures soon. The OEM wheels look like the below image. Image is taken from the goo-net-exchange website.

    • Welcome Gabriel. At least your car has a glorious RB and not the shitty CA18. As MBS206 mentioned all the good bits can be added later. Two doors or four?
    • And half of them have been converted to turbos.
