No offense to Stillen SC owners but the kit has no TQ and unless you are talking a mile long straight that kit will not do much above a well built track 370z because of weight and power curve.
The TT setups will give Spohn better TQ, more power under the curve and with his heat management he will be fine. Will the engine last 5 years? Probably not, but honestly unless he is running endurance races he should be good for his track days.

The GTR is built seemless and thus why it holds together. I'm not worried. What happens happens. I will always try to learn and improve. I won't ever give up on this plateform.

As far as the car that couldn't pull on you. That can be so many different things. Mostly driver. But it's also a supercharger. Lol.

I like the idea of doing track-car engine projects in general. Someday my car will have an LS3, which is about as daunting as a track-reliable TT project. More work, maybe slightly less risk. But really, that's all about enjoying doing the work, it's not so much about making lap times. I pass guys in Z06s and Porsches sometimes. Sometimes I get passed by a Miata. Whether I upgrade my engine isn't going to have a huge impact on that. At least, not as much impact as upgrading the driver.

Yea, the need to up-grade the nut behind the steering wheel as I was told by my driving instructor.

I'm going this route for sure.

LS3 + a mild cam upgrade with longtubes, cone filter intake, you're talking about close to 450whp without doing anything to the reliability of the engine, which at this point, is pretty damned reliable.

And it's the same engine that's been in how many cars over the last decade? Parts parts parts galore. I can't wait. I'm fairly sure it weighs the same or less than the VQ37 as well, so that'll be awesome.

As much as I could do this I just can't get passed the sacreligious side of it. A Nissan V8 but defiantly can't put a Chevy motor of any thing else.

I hear ya, but until Nissan has an affordable V8 that can do anything close to the power the LSx can do, I'll just have to get over it. :-/

I know what you mean but every time I hear Nick's car at ZDayZ I get some tingling in my pants.

RCZ · 06-05-2013, 11:34 AM

Holy ****! What a nice build. Beast.

For what it's worth I have two track weekend (4 days) this season on my boosted performance single turbo kit. I have had no issues with oil or water temps at all (no different that prior to going FI). This is with a 34 row oil cooler and CSF radiator and stillen fascia. I also have an accusump to help keep oil pressure up since my home track utilizes a portion of the NASCAR banked oval and top end oil starvation is my biggest concern.

That's nice to hear. With single turbos and there mounted location heat is not a issue. How much boost/ HP you running.

hey spohn i ordered the 18G MHI kit aswell what spark plugs are recommended for this type of kit? If you can help me out or show me link to read up on this info?

Thanks.

SPOHN · 06-09-2013, 05:49 PM

NGK or HKS plugs. As long as there one step colder. The NGK plugs are the exact same ones that go into the GTR. Easier to find also.

So I pulled out my main AC unit today from under the dash. Oh my god what a bitch. I don't know if there's any other component on the car that requires so much work to remove. Anyways, now that the rest of the dash is in shambles and the steering wheel's off, etc, I was thinking about going ahead and replacing the steering wheel with aftermarket. I know you've already done that...

I assume we get to keep the control stalks for wipers/headlights/etc, and that the black plastic ring thingy holding a bunch of wires is all about position sensor / horn / airbag that I don't care about and can go. Any recommendations on a hub/wheel setup?
