1993 R33

[r33rb25det1993]

Hello, I have a 93 r33 with a 2000 rb25det and I think it has a older s1 head, it has the single ignitor up the back of the motor, any one know if this set up affects the compression ratio? Also it is blowing white/ blue smoke all the time and a bit of black at higher rpm, no oil in the coolant and not water in the oil. It has a front mount electronic boost controller and a 3in cat back system and I don't think it has had a tune. Also before I got it, it was ran with no water and the head was replaced with the older s1 head. Should I replace turbo seals and or valve stem seals?

The ignitor system has nothing to do with the head, just to do with the ignition system.

The smoke will either be because of the turbo leaking oil or the engine burning oil. You could do a compression test to try and work out if it's the engine or turbo that's causing the smoke

what makes you think it has a 2000model rb25det?

and also, in other words u think they have used the block n pistons from the 2000 but slapped the head and ignitor system on from your 1993 model??

If you have a neo bottom end and non neo head you will have very low comp.

That would be shit.

Rta paper work states it's a 2000 rb25det and from what I know a single igniter at the rear of the motor means s1 rb25 also a comp test showed between 120psi - 155psi .... The motor now has a slight knock so it is almost pulled out and a second hand rb25det is going in

Doesn't that just mean it was imported in 2000?

My 96 r33 says 2003 and it's definitely not an rb25 neo
