Hey Brian,
Any dx on the motor? Was it a lean A/F or the warmer weather inducing knock / detonation or what? Begs the question if the Unichip is capable of monitoring and preventing these types of bad outcomes? The UTEC advertises its knock detection - does the Unichip also do this? Does the Unichip keep any data logs that can be examined?
Just wondering if you'll ever be able to figure out what went wrong exactly...

i don't think the unichip detects knock.
sorry to hear of your outcome, BrianlG35C. i too, suffered from FI abuse with the APS TT pretune. although my car did not have a drastic detonation effect, my conrod was bent and the wrist pin was cracked. the engine had a ticking noise that was unbearable.
been a bit over a month since the car has gone to the shop for a new heart... going with GTM spec billet rods, overbore wiseco pistons, 5 angle valve job and some good ol' artisanship.

Why not find a long block (assuming yours is beyond repair) and ship it down to SGP Racing for their $3700 short block upgrade.

You might end up sinking $6-7K in it, but you will probably end up with a rather reliable long term solution.
The realities are that a loss has been incurred and it will end up costing you no matter what you do. If you can swing the cash flow, you would probably like this result the best - and you might even be inclined to squeeze out a few more WHP!
I went down to GRD and rode in their APS G35. They made some rather confident sounding remarks about the OEM block being able to handle WHP in your range, but I didn't buy it. Then I wrote to Peter at APS and asked his opinion about the limits of the OEM engine. He told me they don't recommend anything over 380 WHP with the stock engine.
As tough as it is to swallow, it seems necessary to budget an additional $5K in a TT install just for an engine rebuild. That pushes the realistic price of a "do it right the first time" TT to at least $16K (cooling can't be ignored either). These blown engine stories are far too commonplace and heartbreaking to pretend that the risk is worth it.
Hope you can make the best decision for your situation!

Sorry about your engine, Brian. Good luck.

I think you'll hard pressed to find a $50K car that can outperform a fully built VQ35. I smoke stock vettes all day long, no problems, on LOW boost. Crank up the boost and I slaughter stock Z06s.
For most people it's not about just having a fast car. It's about taking a stock car and getting the most out of it. If I, for example, bought a $50K car I would still plan on putting $30K in to it to make it better then it was from the factory.
The G35 is a really good platform because you get a pretty good deal on the car. I love the stock handling and supsension, and the VQ is a start towards performance. I basically view the G as a great handling car that only lacks power. Spend a few $$$ and build the motor and you'll be left with a great car.
