36pph Injectors + 3.1L + '730

Shouldn't have any real problem getting this idle, right? Going to be running $58 code... working on the conversion, and (think) I just ordered a G1 adapter from Moates.net

Plans are:

3.535" bore
3.31" stroke
5.7" rods

TGP rotating assembly (waiting on the Mahle pistons)
.50mm overbore (just to clean it all up)
FWD Gen III aluminum heads
Custom headers (1.5" primaries, into 2.5" collectors into 3" turbo inlet)
3" turbo-back, no cat, and ditching the POS flowmaster muffler - thinking of running no muffler at all, just to see how it sounds - Bassani muffler down the road
T61 turbocharger (still, lol)
36pph Mustang injectors (how it was listed... when they arrive, I'll get the actual p/n, to find out what they're rated pressure is)
Walbro 255L pump (on the way)
1.6 roller rockers
Solid flat tappet 215/215 @ .050", .464/.464" lift (with the 1.6 rockers)
Custom intake (obviously) and plenum, with a 75mm LS1 throttle body.

Should a '730 running $58 code be able to run that, turbocharged, with up to around 12-14psi? Or would I be running into problems with knock retard due to the solid cam (will be running a tight lash cam), or too short of injector pulse duration due to 3.1L with 36pph injectors, or anything of the sort?

I'm planning on starting with the TGP data, stock, and tuning from there. With the exception of a cam, intake, and headers, I think the stock TGP data (I'll basically copy the VE tables and timing tables into the $58 code, as a baseline).

As a matter of fact, I'll be running the SD system on the car as it is, before the new motor goes in - so I should be able to get close enough to finish cam breakin, check the lash, and start tuning.....

Anyone have any problems with KR + solid camshafts?

Appreciate your thoughts, guys and gals.

I've got the 60 PPH injectors on my 3.8L.
The problem is some injectors are what you might call being linear at small pulse widths, and they can take alot of work to iron out idle problems with (ie running them at short pulse widths).

The Buick TR, and Syclones all ran 30s so, you're just slightly larger then what they used in oem form. So it's just about how your's do at the shorter pulse widths.
