Hi guys,

finally got my motor from the engine rebuilders yesterday. So happy with all the work done and a way too long list of works done in the internals, keep it short it has a 25de head with 30e bottom with the normal internal works. Now the motor is going into a R32 GTST, has anyone tried fitting a GT3540 ball bearing(copy) turbo on the stock oem exhaust mainfold?, my worry is if it's going to fit in the engine bay when i drop it in . The turbo fits snug on the on the stock exh mani without clearance issues touching the head/rocker covers. I'm not upgrading to a topmount stainless steel manifold unless it's quality stuff( SINCO/RIPS) one's approximately $1700 and a good quality Holset turbo hence why im sticking with stock mani and nothing in between, btw i bought the turbo for $300 which suits me for the run in period. This was all due to the $4600 spent on the 30det motor build.

Any suggestions and help will be much appreciated. BTW Merry Xmas ya'll.

Should fit fine with a 20mm spacer. There will be plenty of fabrication work to do though. Is it internal gate?

A $300 Chinese knock off doesn't sound like a good idea if you have just built a 25/30, and the turbo cost is nothing compared to the work to fit it. Hence why people recommend the Hypergear highflows.

Im gonna put my hand up and say it wont fit on the stock manifold. I always though a GT30 didnt fit. Its pretty tight in a 33 with a 10mm spacer.

I could be completely wrong though.

Only way to know is to try!

      ugently need expert / experienced opinion

      There are certain tasks, like replacing head gaskets, where it is very much best to already know what you are doing, and if you are not already an expert, then the next best thing is to have an expert around to help it get done. Little annoying checks and steps that are easy to forget or not interpret the results of properly, etc etc. It is hard to convey that to someone as a lesson prior to taking on a job, because there can be a whole list of "if you see this then it means that", or "if this is what you find then you will need to do these other 4 steps first". All the little bits of knowledge around sealant choice (ie, sealant at all? or no sealant? sealant only in certain parts of the gasket? sealant for this type of gasket but not that type of gasket? etc etc) cleanliness checks and methods, surface straightness and finish checks and methods, etc etc, all combine to mean that people who have done many of the same type of job will struggle less to get a good result than someone who hasn't done it before. I've been around this stuff since forever. But I will still consult with my expert(s) before taking on the big stuff with higher risk profile.

      Well if I end up having to do the head gasket I will certainly find the necessary tools and instructions before beginning... Let's hope it won't come around.   Definitely. Depends on the job but I think "if you want it done right, do it yourself" applies almost every time

      Mistakes were made, my R34 Story

      Can you at least move to a location without so many ladders, black cats and mirrors precariously propped up ready to be knocked down? Or buy yourself a 1 ton bulker bag of salt to drag around with you. Just, you know, sling it over your shoulder?

      RB25 Oil Pump Regulator Washer???

      By GTSBoy · Posted

      Meh, what's the worst that can happen? If is is supposed to have a washer, and: the spring retainer seals reasonably well on the surface, maybe just allowing a little bleed of oil out, and the spring does not coil bind when compressed that little extra bit, then the end result will be slightly higher relief pressure setpoint, and no other noticeable effects.

      Weirdly I see a flat washer on aftermarket pumps but as you said it doesn't seem like new OEM pumps have it. EPC doesn't break out the regulator as a separate component either. I'm guessing if the pump came that way it's safe to use as-is.
