5.3 is good for 6psi non intercooled. 9psi with an intercooler. not sure of absolute limit when running good fuel. we havent found it yet and have gone 9.50's at 15psi.

It kinda was. I have two stock turbos at the house. I found a malibu around our area for cheap. Wife shot down that buy and told me to wait till my engine in my Buick goes. She is a buzz killer...

So the "MAN" way I see this is:

Honey go ahead and buy the engine and tranny and whatever else you need to do the swap. Then when the engine blows you can make it a easy swap for yourself.

So why did you choose megasquirt over using the factory 5.3 computer?

turbo400 tranny with a brake
msd box for ignition control, runs stock ls1 coils and provides tach signal to the megasquirt
megasquirt for fuel. also runs fans, fuel pump and boost controler.
we tune it ourselfs, easy to do with the squirt. keep it safe and conservative. 15deg timing at wot and around 11.5-1
no alkey. pump gas up to 9psi, whatever kind of race fuel above 9psi.
used 2001 zo6 cam($75), patriot gold springs.

it is much easier to tune with especily every time you make a change like when you give it another 2psi or make a cam change. also the software and hardware to tune the factory computer isn't real cheap.

the 2 step on the msd kicks ass too.

Parish8:

How much would you charge Ball park range for a custom piping for a turbo kit and then a tune with the megasquirt? With the customer providing the intercooler, wastegate, and turbo(s)?

thats kinda vague. pm me the exact set up.

typical for a squirt with install and decent tune is probably a little over $1000. more if it includes a trip to the dyno.

Please excuse my ignorance, but how easy is it to integrate megasquirt into the stock harness adn computer?

we just get a premade harness for the squirt and only use the stock harness for a few wires like if you want to keep the factory gauges.

I have a 02 lq9 6.0 on my engine stand ready to go in a fox body.I put an 02
zo6 cam,ported the 317 heads,patriot gold springs,good pushrods,GM 5 layer head gaskets,ARP headbolts and rod bolts.I'm planning on using the truck manifolds and a cheap turbo BW or maybe masterpower 76mm.Parish what do you suggest for a convertor,I know this thing is going to spool good with the extra cubes and 10.1 compression.Cheap e-bay intercooler,leaning toward a 50/50 mix 0f e-85 and 92 or straight e-85 with some pretty big injectors,hows it sound so far

Forgot trans will be a 400 with a brake,rear gear 3.08 28" tire race weight of 3000lbs

that sounds like a great set up. we have a precision 9.5" suppose to be a 3400rpm stall but it is more like 5400 . i would not go with another precision converter for a turbo car.

i haven't tried one yet but i hear good things about ultimate converter. a local supra guy(800hp 2jz with th400) was having problems with their precision converter just like us even after multiple re stalls. went with an ultimate converter and gained 10mph in the 1/4 while still having a 4000rpm stall speed. in fact i know another turbo guy with almost the same experience. thats 2 that tried precision and ended up with ultimate.
