Good timing on this post. Having issues with my 5k mile engine with low oil pressure issues. I have an AMS shortblock, but I will say I don't blame these issues on AMS. The previous owner of the car, and the guy who paid for the build, transferred a lot of parts from the 78k mile stock longblock to the AMS shortblock. Timing chains made noise since I've owned it, valve stem seals are sucking oil on heavy decel from at least 3 cylinders, and I believe it knocks because of that very reason. Not good for the shortblock.

Regardless, I'm on the hunt for a new longblock. I don't want to re-use a single bolt or sensor if I can avoid it. Just found RD Engineerings website and pricing seems great, logged on here to do a search. RD sounds promising.

But at RD you will have a long wait. They are really backed up.
That's a good sign that you are in the right place, they are probably fixing everyone else's mistake on the west coast lol. So far I have 3 independent referrals to RD, one of them being a personal friend who has a built Evo so it seems that's the shop to go to.

*+1 I didn’t want to mention specific shops I have not dealt with directly, but think for your goals you should have no issues with those mentioned.

I’m a big fan to try to remain local if possible. Everything from track support to random gremlins.

I agree, and there are other shops in the Midwest besides AMS. (in a PM only, I'll speak to that)

When I bought my '15 used from the original owner in the Summer of 2019, my car had had all of its modifications done at RD Engineering. FBO plus his "RDE800" turbos. The car was extremely well-sorted and drove beautifully. Ronnie was tough to get a hold of but when I did, it was easy to tell that he lived and breathed GT-R's. You'd be in good hands there, I think.

You can go with Ronnie at RD Engineering in Oxnard or James Wie with ACG in San Diego. Both are good. I would not go to SP Engineering, although they built my engine and I have not had any issues with it. I had to replace the transmission and trubos, though.

RD uses a 30mm turbo setup to get close to 1200 at the wheels. That is a very fast spooling turbo. I have the elite prime turbos on my car which are 35mm turbos.
Damn 30mm and 35mm is pretty small.

The Elite Prime turbos are 58mm in the stock turbofold. I have them on my car. The stock turbos are around 52-53mm I believe.
Not sure if the compressor inducer or exducer is being referenced here. The stock sizes are below.

OEM GT-R turbo Specs​
Compressor (6+6 blade design)​
Inducer 43.3mm​
Exducer 56.1mm​

With the reference being 58mm for the Elite Primes, that's the Inducer size as I have the 55mm Elites and that is also referencing inducer size. OEM is 43.3mm if that's what we're referencing.

^ LL is correct. I never proofread my comment before posting it. I meant 43mm NOT 53mm when referencing the inducer size on the stock turbos. Apologies.

Tim Lynch, LynchMob Racing, Alpharetta, GA., best in the country IMO. I would not hesitate to have either of Cicio's shop's, Tony at T1 (I think he will only do your build if you install Motec) or Workhorse Performance do a build for me.
