PT6766 CEA question

Putting a plan together to get my Syclone out of Moth Balls(15years). Trying to read over old posts to find the best formula to get it in the High 10's with the stock bottom end. Will the Precision PT6766 fit in the stock location and be able to keep the AC intact? Also are high 10's possible with stock exhaust manifolds?

What ever it takes!!
Re: PT6766 CEA question

To answer your question Jim. The 67mm is the biggest turbo you can fit with the AC without having to trim away metal and is good for high to mid 10's.

Thanks for giving me the exact answer I was looking for. Now I know what turbo I will be going with.

Re: PT6766 CEA question

Syclonejim what are your plans for a build and supporting mods?

The short list are Vortec heads, modified intake larger injectors, 3k stall converter and Steve Morris cam. Not sure what route I will go with tuning at this time. I assume the ATR double pumper should provide enough fuel.

Re: PT6766 CEA question

a single 340 or 450 should be fine at that level. I have a 67 in hiding, and got that one specifically to be able to retain the AC.

From what info I could find the ATR double pumper consisted of two 190lph fuel pumps.
I haven't touched my syclone for so long, forgot everything except the beat up hands and cursing while working on it.
