GTM Performance Engineering: VQ37VHR Twin Supercharger System

chii370 · 05-13-2013, 01:34 PM

wish someone would make one...... and make some kind of low profile blower that could sit under a ram air style hood so it doesnt have a giant stupid looking blower intake sitting in the way of what i usually need to see while driving :P wasnt tryin to jack the thread, sorry about that. its just that this is a big choice, i dont have an EXTRA 10g to press the reset button if i **** up the first time. normally, i want response. and normally i dont consider turbos..... but DAMN already over 450rwhp at 3k rpm..... if thats what you call turbo lag? i will take it. not to mention its not using the usual 9587645976 PSI required for a typical TT to produce big power that early so my engine wont explode after 50k miles. clean oem look....... ok i will stop now.

although ive been following this thread for like..... EVER. since the last guy wimped out when his car didnt make big *** power on its very first dyno run and put it back to stock..... that was a good half a year wasted waiting to see some damn results. one would EXPECT this kit to go far and above what a single sc, and maybe even what their stage 2 TT can do for how much it costs, and how complex the installation is. but we shall see. believe it or not, im actually rooting for this thing to be the next sliced bread 2.0.

Remember GTM sells their Garret TT kits and the MHI kit. No need to ask about a competing vendor on this thread. Chili, unless you plan on pushing serious power, you don't need a built motor. If you are looking for torque, go TT's, if you are looking for response, get a SC unless you don't mind waiting for the half second it takes (maybe less) for the turbos to spin. If you are looking for instant torque and response, sorry, there is no twin screw or roots blower options here.

Cheapest two ways to get boost.

GTM TT Nismo... This doesn't look stealthy and stock? You could even go with black tubing and inner cooler for even more stealth.

That's what I did. It looks awesome.

Lol. Good read. Needed the laugh. Interesting the mods haven't "cleaned" up this thread yet.

Haha, this is "cleaned" should have seen it last year. It was like a meteor heading for earth.

Torque kills stock motors not hp IMO

So tuning has to be good to keep a stock motor running for a long time with a lot of torque
Else your one hard pull to boom

Whats the weak spot in the VQ? The piston connecting rods? I thought the VQ was pretty rock solid until you start pushing its RPM limit a bit. Would imagine the boys at nissan set it at 7500 for a reason "nismo" ;p

Chuck33079 · 05-16-2013, 08:38 AM

I've been told the rods are the first thing to go. The oil pump gear has reportedly been the first point of failure if you raise the redline too far.

SS_Firehawk, this will be you one day:

There were some minor delays for the past six weeks that slowed things down. Basically a previous shop had my O2 sensors wired wrong, the upstream senor in the LTH J tube, and the downstream O2 sensor in the freestream tube just after the merge collector. I have the pics in my journal, but don't want to post it in here as it really doesn't have to do with the kit it's self. Also found out CSF radiator won't work with this kit, Z1 hoses don't work as it has it's own, my AE performance oil cooler is too big, and won't work either...

Soooo.... I replaced it with GTM's 70mm radiator, SPAL fan and shroud, twin 25 row oil coolers, their new baffled oil pan, and had them take care of the sensors issues. Good news is the ECU isn't fried and only needed two new sensors. Posted a small thread on that issue too. Bad news? My wallet is feeling the pain of the upgrades. So with the help of GTM, I have a for sale thread going to help clear out everything that didn't fit and to recoup some lost money to fund this project. Hopefully it wraps up in the next month or so and GTM posts a thread on the project.

Glad to hear the ECU was not friend, sucks on a lot of parts not fitting but people will jump on your for sale thread.
