GTM Twin SC. How to not destroy my car?

faceglide

Man...the **** that people say nowadays....

12.5psi/600hp/530tq....7000 miles....almost daily driven, commute, traffic, uphill, stop and go, you name it. Not a single problem, not one. Starts up every time, not one stall, no hesitation, no CEL, nothing. Stock block btw.

There are 3 of us doing this....2 daily driven, one being tracked as we type. I hate to say it, but we doing very well.

PM me, or you can call Tony@FI.....we can talk shop or he can get you set up.We can give you realistic expectations on what this car can and cant do, I live your goals daily, no speculations, no google, no BS.

Happy boosting my friend! We got your back!

....sigh... faceglide when u speak about ur numbers you should note that you're on e85 and not pump gas which EVERYONE here uses. The $hit people are talking of are PUMP gas. Not everyone has e85 readily available and not everyone upgrades the fuel system to take e85 gas.

Can't compare your numbers to pump. I don't see anyone here trying to run race gas and then comparing them to pump gas.

For everyone else, just read his signature and you will see how he got such high numbers. You will NOT get those numbers on pump gas. Don't be mislead.

Actually I was talking about the constant GTM bashing....my sig is in every post, i figured it to be sufficient.

Its just a bit tiring to hear someone inquire about GTM stuff and have them get bombarded with the bitching. We get it...stay away from GTM, they have been branded.

I am not misleading anyone, I would rather him PM me about my build and how I got there than make a post about it and become a FI vs GTM vs BP vs VSR vs whoever else got there. If the OP is interested in my build I will talk to him about how I got there.

I am sorry if my intentions were not clear, I am glad you guys have his back, but am fearful for this being another "torches and pitchforks thread". I am pretty tired, so maybe I was not clear. But the OP said 600hp on stock, just want to help the man out.

elperuano

That's cool.
It does get tiring of the constant bashing but I suppose it's to inform the newcomers of potential headaches that will happen and unfortunately many don't use the search feature and dive right into the deep end.
To the OP would be best to speak to the main forum guys and your shop installer on the best way to go. All the experience is there for u to read.
If you want the absolute best twin turbo option then FI is the way to go. Faceglide has an absolute beauty of a set-up and following his build will get u those amazing safe numbers on the stock block. Even running pump gas you will still have the best available twin turbo option.
If SC is ur preference then there's just not many options there. For ur power goals you'd be better off going turbo tho.

There's also single turbo options of BP and VSR and I believe JTran has a kit coming out or already out just have to speak with them.

faceglide

Indeed. The initial "stay aways" are warranted, its the lingering comments that just pollute so many threads...unnecessary.

It is great that we have each others back though. In the end, a mistake may have been avoided.

OP
*TUNED+install(even BP, I would have a pro at least look it over to check your work, wouldnt cost much)
*FUEL SYSTEM
*COOLING

From there you have what insurance you need to keep things safe. Always overshoot, do not skimp on these things(or anything in your build).

Correct me if I'm wrong faceglide, but the Complete FI kit comes with everything I'd need for fuel and cooling, does it not?

Fast Intentions Twin Turbo Complete Kit (650cc injectors) ($10,000)
+34 row Oil Cooler Kit ($500)
+GTX3867Rs ($425)
+Bosch 850cc injector ($50)
+Uprev Tune ($550)
+ Labor ($750-1,300)

~$13,000?

What will this put me @ in terms of Whp/Torque?

+Clutch Master kit ($450)

faceglide

Basically yes, but for goals beyond what 93 can push, you would look into upgrading.

faceglide

OH and a completely stock fuel system with pump and relay will still show some pressure drops in fuel pressure right around the 500hp mark. This is why I would recommend a FAST500 type system to be safe.

Is it ok to run without? Yes.

Would I personally live with it? Hell to the no.

ourdelusions

Can't imagine needing more than 900cc? Thoughts?

1slow370

the twin supercharger kit should do 600, SSFirehawk is at like 560 and he is on the 92mm pulleys not the 88mm ones on pump gas. They have ones smaller than 88 too aparently. The ID1000 injectors are very popular, you can't go wrong with injector dynamics, that doesn't mean that cheaper injectors wont work fine. IF pump gas you will be fine with 800's on e85 you want a little more than that for the power you are looking at making.

And he had so many problems that he traded it in at a loss of $15k (and I'm sure he got hooked up for being a guinea pig,) for a stock Nismo.

Yes you're precisely the type of dicklord that keeps me off the FI forums. You're running E85 at a lower pressure with an E85 map and you're telling this guy there's no risk in a FI conversion. Seriously, what is your problem? Are you trying to trick someone into blowing up their motor because if so, you are a **** of the highest order. My bet is you just love hearing yourself talk and want an excuse to post your numbers. **** off.

Guy who initially posted this, please do your homework and don't listen to dickwagging asslords like this dude. Unfortunately, the FI community here has become a cesspool of jerkoffs looking for bragging rights and not people looking to offer real advice. I'm done with this thread but I'll leave you with this:

-FI conversions are risky no matter what.

-My guy with 20+ years of working on Z cars says that you shouldn't take the VQ motor over 550whp on pump gas without building the motor or you are playing with fire. You do not have forged internals. You are not a GT-R. Do what you will but ask yourself how much juice you really need for what you use the car for.

"I live your goals" lmao what a ******* douchebag

Someone said sumthin earlier about that which fit perfectly fit just now.

Depends on goals and fuel

Anything gasoline, 650cc and you are golden. There is no need to go higher without e85 because I wouldnt trust the stuff past 550 on 93(even that is risky).

I am talking about a return correction. It has been seen on almost every car that there is a loss in pressure at around the 500hp mark. I would beef up my system just to avoid any problems related.

It all depends on your goals and package. There is no blanket answer for any of this.
