I think you should give the dealership a try. I was lucky. I told them that I was probably screwed from all my mods but to check the car anyways. SOA decided to swap my motor. Although I had my built block ready to go I decided to just ride out another stock block.

always something interesting going on here. GL with the rebuild.

pretty sure upgrading the turbo voids your warranty if he did take it to the dealer he would get charged diagnostic labor hours

LOL. I wouldn't let this scare you off. This was considerably more power than Stage 2.

I'm surprised you broke it with E85. The lower cylinder temps and high knock resistance usually make it pretty safe. It'll be interesting to see if it really is a cracked piston.

Yeah, I have the stock exhaust, so it's even quieter than the SPT. Definitely makes a lot of noise from the front once the EWG opens up though.

I noticed the turbo was spooling really slowly (like 5-5.5k) and it wasn't hitting peak as high as it should. The idle was very slightly rough and vacuum was about 19inHg, compared to 21inHg normally.

I noticed this all on the drive home from work one day. At first I thought it was just a boost leak, but I couldn't find any leaks. My tuner suggested it could be a cracked piston, and when I opened the oil filler cap with the car on it was chuffing, so I did a compression check and the results were low compression on cylinder 2.

My car usually shows 24-26inHG (Defi gauge) on startup/idle, what's the normal range?

cold obviously, when your car is up to temp it should be 20-22, 20 is acceptable.

That's a bit odd. Most I've seen are around 21-21inHg (or about 10psi).

That's one of the main purposes of a boost gauge. Vacuum readings can tell you a lot about leaks, etc.

the best tools in my car are wideband/boost gauge, my first mods too, you dont want to be romping on these cars if there's an issue..

X, your lucky you have E85 by you, I have to travel for it, making it not practical for my dd, the power that can be made is ridiculous!

Looking more at the cost/labor/downtime, I'm starting to consider parting out or selling as is...

Sad news man. Of course...this does mean it is motor build time.

I am going under the same assumption you basically did. Run the stock block until something goes wrong - then build it up. I'll be running a DD tune on 93 most of the time though...not sure if that will make a difference one way or another. E85 is pretty safe.

you should just find a cheap stock engine, throw that in and drive around at low boost while you build your engine then sell one when you are done

back to the inHG thing. Mine is right around the 22 line when its warm. That arf80 guy said his is 24 to 26 at start up, that seems backwards to me, the number is lower when your revs are higher.

you probably don't care at the moment

LOL. But I do agree that it should go closer to 0 when you rev it higher (or at cold idle).

Simplest explanation? His gauge is off. Double check it through the OBD-II or pull a vacuum line and put a mechanical gauge on it.

Good idea, I'll log via the Accessport. The gauge does measure boost perfectly though, it hits 16.5 PSI exactly where my map says it should.
