RJM GTR Intake Conversion

RJ MFG · 10-27-2016, 10:09 AM

Gentlemen, at this point all our customer supplied data outside of our shop car have multiple changes including lower compression. We will state that with the GTR manifold many customers are EXTREMELY happy with the performance! Two customer specifically have for the first time maxed out the Fast intentions Stage 2 Twin Turbo kit! Something no one had been able to do on the stock manifold. Neither customer lost power anywhere in their graphs. Power continued to climb all the way to redline. Two separate tuners and both making ~800whp on the Fast intentions Stage 2 kit!

I see the benefit for guys running more than say 20 pounds, as someone said earlier their plastic manifold started to go at around 30 psi or so.

I'm interested in what this is doing for guys NOT maxing out, running lower boost levels, 10-18 pounds ( like me ). And more specifically guys running single turbo systems. Do you have any data showing gains for top mount or BP cars?

This. I just want to see what it does, by itself, on a relatively mild (~500whp) build.

The shop Car and Tim's car are both stock motor single turbo cars. Both have made gains of 40whp+ stock for GTR conversion. Both are running low psi tunes. Tim's car was making ~500whp on his single turbo kit and 8psi on the stock intake manifold. Now he is making 540+whp at 8psi... He is also now revving to 8300rpm! He is loving both the GTR conversion and his billet oil pump gear.

Is he making 40 plus hp because of the manifold though or because he's revving all the way out to 8300 rpm ?

Not trying to be difficult, just making sure I understand correctly as I'm in the midst of reworking my setup. This is a potential addition, I like the concept but I want to know if it's worth my money.

Also, the charge pipes on pretty much any kit would have to be modified to work with this correct ? or do the FI ones fit as is

See that you have a single turbo. Take this with a grain of salt, a lot of guys with singles have trouble with the peak power falling off drastically, I talked to a guy at z nationals who had this set up with a single and lost 40whp from 6k to redline. Now my buddy who has a twin set up made 790whp and made power to redline. To answer your post, there was alot of questions about that dyno run to much to get into ( the thread is somewhere). The car didn't really make power to 8k it kind of just leveled off from what was shown on the graph.

Lets go ahead and nip this in the butt... The said client did not give the tuner ample time to tune the car given the issues the tuner faced with his setup. The customer also declined any support from us. We sent over tuning files for Z1 to use to fix his specific issue as we had experienced his exact issue before and have the fix already setup for a single turbo kit. Again let me stress the client (who we also sold his kit for him) DECLINED support! There is NO issue with the product and single turbo applications. We have a clients car in house that is making power to 8300rpm on a stock 370z motor...

For those reading this thread we offer full tuning and client support with all of our products. We stand by them as we use them on our personal cars and test them rigorously.

Thank you,

How are they revving to 8300 on a stock block if you dont mind me asking? Do they have an IG? What Single Turbo kit?
