Well, yeah. If I could afford a 918 I wouldn't be here. Maybe I should qualify my posts a little bit.

I'd like to think that if I had that kind of money I would still post here. It saddens me that you feel we are low-class people unworthy of the company of those that have money.

:p

:stirthepot:

lol nothing wrong with ebay turbos, just make sure everything is rebuilt and rebalanced and make sure you have a proper oil restrictor(if your setup calls for it) before installing ;)

it pretty much like buying and rebuilding a used turbo except without the worry of having to buy a new compressor wheel

I blew mine a while back.

I installed the turbo kit myself the first time. Then I got an exhaust leak and got lazy and had a shop pull it to change the gaskets on the headers. They weren't as careful on the routing of the vacuum lines for the boost controller. One of the vacuum lines got a hole burnt into it and the boost controller controlled no boost that day..and let's just say 16.6psi was more than the stock block could handle. Needless, to say I handled the installation of the new short block. Good shops are getting harder and harder to find these days.

Edited because I'm an idiot. Carry on

Man,

Those are some crazy pictures! The pleasure and the pain involved with this sport. FortuneLSX-TT, you are very right about good shops becoming hard to come by these days. I almost had a catastrophe myself because of shoddy exhaust work. Luckily GTM resolved much of this. I am a believer that excellent, not just good, installation and conservative tuning are key on these builds. Did you build your block (pistons, rods, etc) after this incident?

Nope, I just dropped in another stock block. Found a good deal on one. I will eventually be dropping in a built block. The price on parts for building the motor is just a hard pill to swallow compared to performance parts for other motors.

Typically a stock Nismo gets ~290 WHP but is listed as 350 BHP.
83% makes it to the wheels. Or 17% is lost.


So lets say you modded it to output 500 WHP, working backwards is 602 BHP. Which is a hell of a lot of power for a production engine.

I'm not convinced that 17% loss is constant for 290whp and 500whp range of power. I think that loss is different at 500whp.

Your right, some energy loss is constant regardless of the over all power. Like your coolant and oil pumps.. However some losses are added and or proportionally increasing with adding FI, additional turbines, bearings, etc.

Unfortunately I don't see anyone testing the BHP output of a FI'd motor anytime soon. The best case is just a constant loss of around 60hp would be like 560bhp worst would be like 610bhp. Something in the in between would be most likely the best guess.

I'm thinking of a Stillen SC install over the winter. Totally unconcerned with reliability as I have no need to be the fastest 370Z in CT. I also have a quality shop to install it and tune it properly. 400whp is fine with me. Hell, my car is fast now. Looking forward to it.

Well, with the amount of money I blew on my setup, I drive her hard. GTM felt very confident letting her go at 550whp, who knows what she's making now on meth (they did that too). Tuning is super critical like everyone says. For what was an NA V6 to make this kind of power on stock internals is impressive. The 6MT, while I won't say is bullet proof handles the power just fine. If you didn't cut corners in the planning and don't get power hungry, you'll be fine (95% of the time)

True Dat. You can't go wrong having GTM do the install, for sure. And Nissan did not cut corners on the internals, hence the reliability. If you had told me three years ago that the VQ37 could be fed 12psi reliably, I would have been like gtfo.

I Babied mine only got on it once and a whole cly3 took a dump at 457WHP.
Faulty install ( fuel pump and feed line) Stillen SC :(

I've always despised the phrase: "He BLEW his motor!" 99.9% of the time HE didn't do this on purpose, the motor blew.

In my case this is only partially true. I drove it 20 miles before it completely locked up. LOL! Crank bearings = NFG.

I ran five HARD passes at the dragstrip attempting to get ONE clean run. Each time the friggin' fuel cut or some limiter come on and then went off. Almost always in second gear. This has happened in the past, and Jimmy (my builder) told me to hold it up there a little higher. Last Dec I did, and it went 11.13et. Twice.

This time: not so fortunate. Working boost guage with memory never exceeded 15.8 lbs, despite twisting it a turn. Jimmy's convinced that did it. I'm not. It barely went 120mph in any configuration.

I was trying to better the 11.13 time. So STUPID close to the tens, I HAD to try. Wouldn't you?

I had installed 4.08:1 gears and considered this to help. Truth is, on the street this is a GREAT mod. At the track, it didn't let the engine boost OR work. I'm dead certain that was the wrong direction. For me. But I had to try it to find out.

Play with fire.:icon14: Yes, same components I ran before.

No excuses. The dragstrip is HARD on parts. Five runs in a row flogging it didn't help. (All but one were in the mid elevens.)

The car was smooooth as silk and ran stupendous with over 550whp, until 'I BLEW IT' by going to the strip. LOL!

That is all. I'm searching for an OEM engine and will be parting out the performance parts. Soon.

Jim

Sounds to me like he got ****** by a tuner shop FP that had no idea what they were doing and then got strong armed by the shop and its forum following fan boys. Anyway, selfish ignorant comments aside my builds going to be 500 whp w/forged pistons, rods, and heavier springs and retainers to prevent floating, NOT GOING TO SLEAVE. Other than that from every credible source i could ask 500whp is the limit with proper install. Repeat PROPER INSTALL.
