Anyone have a built motor yet for FI?

GambitX · 08-03-2011, 06:54 PM

I just found out today that my rods are bent on my G. So now begins the long process of a motor rebuild that will be able to handle 10 lbs no problem.

For how long have you been boosted? What psi were you running? What HP?

This G had and engine built because rods bent during tuning

Edit: Here's the story on the car: Forged Perfomance and my G37 TT build

Car hasnt even left the shop, I believe the turbo kit has been on the car for maybe a few weeks running. They had a few issues with the cars fuel cut, bovs leaking, and the clutch.

Monday they had everything fixed and before I was to come get the car they called and said they think the car spun a bearing. Then today they took the oil pan off and you could see the bent rods.

Stats on the car is Greddy TT kit, 8 psi, 507hp

here is the build:

Are rods on a G different than on a Z? There's quite a few TT Z's out there pushing about the same if not more and I haven't heard of rod failure... yet.

GambitX · 08-03-2011, 07:58 PM

should all be the same, yah thats why im in shock and pissed at the same time.

maybe if I was running 12 psi or more i would say ok i deserve it but thats not the case

Wow... that really stinks man. This thread personifies my only fear of going FI.

Two ways to look at it... crap happens, bad luck, etc.

Or shop mistake...

I'd say talk it over, calmly, with the manager or owner and look for explanations of what happened.

BTW, I've not heard of this place and have nothing against them... just saying one of two things happened.

Damn, sorry to hear that. We finally have a data point for where the stock motor may be over-taxed. The speculation forever has been 450-500WHP. Best of luck getting it all worked out. Maybe they will throw in labor and you will just have to pick up some forged internals.

this actually proves how good GTM is when working on this platform. so far don't think anybody has blown their motors installed and tuned by Sam.

Armonster · 08-03-2011, 09:34 PM

What did your torque curve look like? That is really the more useful "data point" to be gained here, IMO.

OP,
Engines are not created equal.. I hope the shop steps up for you and takes some responsibility.
GL!

While I am sure GTM cars have had issues, I would have to say that at this point they must have the best ratio and IMO the better products for the Z34... there are GTM FI cars "all over" and to this point I haven't heard of a failure. Again, I am sure it happens but law of averages...

I mean, I agree with you and I am certainly not trying to start a GTM vs. debate. Simply pointing out that there are far more GTM builds than anything else.

no idea, they never did one from the dyno. Again things I couldnt control not being there all the time.

GambitX · 08-03-2011, 10:48 PM

I can say this, Sam at GTM has been helping me with questions and concerns the entire time through the build. He is a very honest person and I wish I could have sent my car to him 3 months ago. Im sure I wouldnt have the issues I have had so far.

There still hasn't been enough FI 3.7Ls yet to come up with a "safe" HP range. There are plenty of FI 3.7Ls running over 500whp, including myself. It's all in the tune... and a little luck.

If im not mistaking the g37 weighs more than the z therefore taxing the rods even more. My auto convertible was the same problem because it was so much heavier at the same horsepower as other coupe manual zs, it had much higher loads to handle on the rods and mixed with horrible tuning is a bomb waiting to happen.
