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

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.

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.

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.

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

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

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.

Hello new to the skyline world. Hope to find some good info here and maybe give some.
