finally running!

[93_tsi_fwd]

I posted a thread about 5 days ago saying if it was okay to put a non turbo piston, rods and new bearings on a 6 bolt turbo block, well I didnt listen and deleted the thread.

5 days later! I got the car running with the non turbo pistons, rods, and bearings.
After that installed the head and torqued it down. Then the balance shaft belt, timing, power steering, ac, and the alternator belt. After all that stuff was done, I continued to the harness, vacuum lines, turbo, downpipe and the piping for the maf-s and maf-t. After everything was completed, I tried to start the car and found an another problem! The coil pack was only firing in two cylinder. Number 2 and 3. I have an extra coil pack for 2g turbo and installed it. After a couple of cranks later I finally got the car started. I let it idle for a while the turned it off then started it again. There was no more loud knocking noise.

I basically made the block a n/t. My extra n/t block in the back yead has a hole in the side for being dropped.

now my question.

What is the safest boost for the block?

After its all broken in, would this be safe for racing?

Any heads up before I test drive it tomorrow?

Theres also something rattling in the back but its not the exhaust?

I believe the non turbo pistions are of higher compression (I think 9 to 1 or 9.5 to 1) and I believe they are not made as strong. I would play it safe and keep stock boost or lower like 8 psi(I believe that is the spring pressure for our 14b) for now and see how the nt pistons do. get a logger and watch for knock as I don't know how strong the NT pistons are(maybe a NT w/turbo member can chime in here???)

as a side note a lot of people run 9 to 1 but the have built motors(i.e. forged internals)

I'm running 8.8:1 on my new build. They're forged Ross pistons, though. The compression isn't a big deal. You can tune around that. The strength is definately where my concern would be.

So you wanna run high boost and high compression? They do it in Europe, it is just a lot harder to tune because of knock issues. Make sure you have a logger handy so you can watch the knock, I would not boost it without that. The main concern, like others have stated would be how much the N/T pistons can take, you may want to ask someone with an N/T, they usually know their shit pretty well.

*NOTE: Don't boost until you let piston rings set...*
