I currently have:
Nismo CAI
Nismo R-Tune cams
Nismo headers
Nismo exhaust

in a
2006 GT (RevUp Manual 6 sp)

I'm considering adding:
Motordyne plenum spacer (5/16 or 1/2)
Motordyne MREV2 lower collector

My questions:
Is anyone using this combination? Success? Check Engine lights? Any improvements on the dyno? Seat of the pants?

If I am not tuning the ECU (ie. stock ECU, with no UTEC or anything), then should I even bother with this since the ECU is already compensating for the cams?

Other notes:
I don't care about the stock strut bar. If the gains are worth it for the .5" then I'll get a custom strut bar if I even still feel I need one.

Thanks in advance!

The best combo was shown to be the MREV-2 and the 5/16" spacer. The 1/2" lost too much power up top.

Though I haven't been on in awhile, you probably have the most complete setup I've seen of bolt-ons and stuff that is considering the MREV-2.

You should definitely look into getting that setup tuned as well.

 

I don't think the Nismo R-Tunes are compatible with Revup engines.

 

He already has the cams on his Z...

 

Only the intake cams work on the rev-ups. Not the exhaust cams. And you are the only rev-up guy I have seen that done cams. Get that setup tuned because I know once you do cams without tuning, it just doesnt read right with the ecu.

 

The car runs great, pulls great, etc. I can feel the cams a bit at the transition point. But it seems like they could do more.

Only problem with tuning is that I would only trust a UTEC, and there is no one near me that I know of who really has experience with the UTEC. I'd be willing to experiment with the combinations and the tuning if there was a local tuner who could do it.

 

hmm interesting. http://www.mynismo.com/products/?id=2501

Perf. Nissan specifically stats the R-Tunes will NOT work with REVUP motors. Who did your install?

 

He got his car like that from nissan japan at the dealer.

 

Hey guys..I'm just gonna say this one time and that will be the end of it, cuz I'm not getting roped into another forum argument. Plus, y'all are hijacking my thread.

The facts:

Nismo R-Tune INTAKE cams will work in the 06 RevUp. N

ismo R-Tune EXHAUST cams will not work in the 06 RevUp. The reason is because of the added variable timing sensor for the exhaust cam.

HOWEVER
The 06 RevUp exhaust cam has a slightly more aggressive grind. This new grind is much closer to the Nismo R-Tune exhaust grind and profile. Thus, the OEM 06 Revup exhaust cams and the Nismo R-Tune intake cams work perfectly together.

Evidence #1: We spoke with Nismo engineers directly and they prescribed my current setup.
Evidence #2: My car runs like a champ with ZERO reliability issues.

Ok..now...back on topic. Anyone have experience with the combo I describe in the first post?

Thanks,

nobody is trying to argue with you man. You are the first to do this so we all just like details/info. I would def. get a UTEC and SGP should be able to tune it for you. They do full standalone setups so they should be able to handle a UTEC

 

I've heard SGP specializes in Unichip. Not UTEC. Thanks for the suggestion though. I think I've contacted every shop between DFW and El Paso, and everything in-between in Austin and Houston. Nearest competent UTEC tuner to me, as far as I can tell is near Atlanta (cant remember the shop name off-hand right now).

I'm very picky. If someone has only done a few UTEC tunes, I do not consider them competent UTEC tuners. If I could get my car to Maryland to have it tuned by TurboXS I'd probably do it.

May just need more time for shops to become proficient with the system.

Cheers,

Theres a couple of other UTEC tuners in the country just all far from you however. MRC was one of the first ones and is making some of the highest numbers on the UTEC but they're in NJ and a quite drive if you'd like to be tuned by them. Shariff is another one that comes to mind as well as AAM but again quite a distance. I say get the mrev2 + spacer as well as a utec and tune for that setup. You pretty much have all the boltons except for stock cats, and at this point you can either add tp's or HFC's and round out the bolt ons(plus mrev,spacer, and some form of EMU)

 

I was thinking of HFCs too, but have heard so many bad things about build quality with the Randoms, and the Crawfords, etc. I always used Random Tech on my V8s. I have a Nismo Y-pipe, which makes it more difficult as I understand it. I'm concerned about flange failure or cat-collapse. Nismo just came out with a set of reinforced-flange HFCs, so maybe after some field feedback I will give that a shot.

But ya...a set of reliable HFCs, an MREV, and a 5/16" or .5" + a good UTEC tune would make my day if it left with me a 100% guaranteed daily driver (no stalls, 100% startup reliability, no rough running, etc.). Plus the UTEC sounds like a fun mod.

If you hear the guys chatting about UTEC on the WRC and STi forums, you'd think they were tuning an RC car with a fancy gadget. Some of those guys either really know what they are doing or they all treat their car like a toy to be hacked. Check it out. Fun stuff to read..

I think my biggest concern is the "unknown" about the RevUp, the new variable exhaust sensor. the combination of Nismo Intake the OEM exhaust cams, etc etc... add in the UTEC and I'm not sure enough folks have experimented with this combination. Throw in the MREV and spacer and you have even more unknowns.

At the end of the day it is just an a/f curve and a some mappings.. but still... my car HAS to be 100% reliable.

I really think I wouldn't mind flying in an experienced tuner to come borrow a local dyno with me for some tuning. That saps me for local support, but if it's done correctly that shouldn't be much of an issue. Plus with a professionally designed base-tune, phone support could be possible.

My mind reels. It feels so in reach, but yet so complicated and potentially risky to my currently stable and happy platform.

Thanks

I say just drive to Atlanta. I've got a friend that makes the drive from Dallas to Birmingham several times a year. It's only about 10 hours IIRC, which would make the trip to metro atlanta about 13hrs from Dallas. That's got to be cheaper than flying someone in, paying for tickets, room, board, plus professional fees.

 

Perhaps. But the added miles and road-wear and tear on the car makes the idea worth it.

Would be cooler if such a "tuner exchange program" were offered. :-)

 

Hey Smoky,

How does the car feel up top? I think you would have a better time getting headers, test pipes, exhaust and then drive to technosquare and get a good reflash for your mods.

I understand UTEC is great and all, but a reflash would also help a lot especially if you want to raise your rev limiter for those cams.

Subscribed..wanna see how this turns out, I have a revup and would love to get a hold of some real info regaurding cams etc...Goodluck smoky

 

Dude, it's a "roadtrip." Completely different

 

I'm not sure about the rev-up, but a CAI and plenum spacer combo might not be a good idea.

evidence:
My 1/4 trap speeds for the following runs:
(this was at different days, but similar conditions and the car was exactly the same except for the intake)
1) Injen CAI w/ 3/8" MD spacer 100.83 MPH
2) Injen (short ram) w/ 3/8" spacer 103.55 MPH

here's the thread with more details:
https://my350z.com/forum/drag/185964-best-time-13-77-s-100-8-mph.html

I had heard ppl talking about possibilities that a spacer + CAI might cause some kind of turbulence issue with airflow, but didn't really think there was much proof for it until I ran the 1/4 with it as a short ram...I've kept the Injen as a short ever since.

*The Injen CAI routes the filter to the front grille area, and I think the Nismo is similar to the AEM CAI (which I've also had)...but I'd assume that the same problems would arise from both designs.

 

Nice!
