[Rb25de+t compression results]

Do all other plugs need to be pulled when performing the pressure test. Or I guess if not all out will it change results.

140 is sort of low for an NA, but the fact that they are even suggests that the motor is fine.

Thought it was kinda low to. Any thoughts on why it is that low?

Motor runs great and pulls strong. Just wondering if 140 across the board on the 25de+t is good.

Does it run good? What fuel are you using? Do you not beleive previous owner for some reason?

It runs great, pulls hard and boost great. Hits 1.1 bar. I use 94 in it. I am just trying to verify the engine. Really wanna know for future mods and for knowledge of the car. As I have only the knowledge of what I have been told and that cast number is the only way I know of identifying it. And I haven't found a solid answer anywhere on what engine it is.

R33 and R34 vct blocks are 75T .   I read somewhere, can't remember where, so don't lay money on it, that R32 RB25n/a blocks had 08U marking.

So it might be a rb25de? Well it has a big turbo and allot of other upgrades, I read that wasn't good for that engine.

RB20Det head marking  73L    RB20de head marking  72L     above number 2 exhaust port.

The number in that spot is 08U. As well as 08U on block. What engine do I have?

[Hello]

If the cast number for head is right above exhaust rail. Then that number is 08U as well.

Engine number is cast on the back left hand corner (roughly underneath the turbo) it will tell you what block it is.

Head casting is front left near exhaust runner 1.

Also RB20 head won't go on to RB25 block as the chamber/bore size is different.

What does cast number 08U identify the block as? And I have read this about the 25 and 20 not matching up.

Hello, 

I have recently purchased a 91 gts-t, I was told that it had a rb25 block and a rb20 head. The block has a cast number of 08U. If someone could help me identify this block and maybe tell me where to look for identifying numbers for the head I would be in your debt.

Thanks.
