Must be 3.5"+ preferably stainless

Showed my engine builder, he said he noticed it but the tests came up perfect and told me it has most likely been there since the block was cast and it's fine to use, so fingers crossed Cheers guys

Just got my block back from my engine builder, who said when he took the block, it was fine to use. He also said he pressure tested the block, however after closer inspection I noticed a small crack between the water jacket and the head bolt, is this block toast? Will it affect proper torquing of the head?

Just an update, yeah the pistons still had a high compression even with the 1.8 MLS gasket, so he decked the pistons he worked the comp to be 9.2:1 Is this still quite high, I have decided to use e85. Turbo is a Garrett gtx3076r, what would be the highest, safest boost I can run, I have all supporting mods.

Cheers for the info guys, getting them flow tested to see what they are flowing.

That's what I thought too, strange thing is there is no logo on any of them.

They came with the car, previous owner didn't advertise what Injectors were in it, however I found receipts for ID 1000s, not sure if he's taken them out or if what I have are ID 1000s. https://flic.kr/p/yBFYhQ https://flic.kr/p/yBFYgh https://flic.kr/p/zxCQfN Couldn't see any injector dynamics logo on them. From what I could make out: >PA6< 927 81187 7-29-03-13 015124

Picked up the pistons, can anyone tell me any information about them?

Turbo will be a GTX3076R, max 24psi, 3.5" turbo back. I have a feeling they are for a r33, that's why he's putting the thicker head gasket to bump it down, he said it won't be over 9.5

My parts provider has been trying to sort me out with some forged pistons for my build, however he said the best he could do was a set of forged pistons matched with a 1.8mm MLS head gasket, he said I would be getting around 9.5:1, is this too high? Will I be increasing the risk of det by much compared to something lower? I will only be running 98 pump.

The de head is a lot cleaner and newer, the det needs new valve guides and looks really unhealthy, the cam cradles are pretty badly scored. Would it be better just to reco the det head?

I got a NEO rb25de long motor cheap and was planning to drop the rb25de head onto my neo det block, I am planning to put 260 Poncams and valve springs and titanium retainers into the de. I know there some differences in the blocks like oil squirters, are the heads the same?

Looking at anything at the moment, PM me what you have.

Bump

Anybody know if a shortblock rb25det block will bolt up to the r34 neo's head with no clearance issues or anything? I don't really want to be using the existing crank so I might just get a pre forged block
