Why 3x when you're going to run EDIS and a relay board?

There is absolutely nothing MSII cant do that you'll be needing. If you want to burn the extra money on MSIII that's fine, but you wont need it.

I bought the Edis but not going to use it, ill drive direct GM coils. I think MS3x has many more features and its more reliable, also i have the electronic boost controller, EGT that makes sense to me to protect the engine, i always wonder some factors when you turbo charge that i never was able to measure because the lack of technology as the real performance of the intercooler (intake temp, air temp and exhaust temp) with all those parameters i believe i am going to be able to develop better the map for my car, and recently i saw in top gear USA the special edition of the 911 and how the car was seriusly affected by the perforance just by the air temp. So for these reason and more makes sense to me the MS3x.

any picture? what boost are you going use? its seems alot since you are using 4bar map sensor

One of the things about this project is that i have enough time to plan everything and look for the better parts for my car and budget.

I bought the Boost solenoid on ebay, this is the same solenoid that AEM sells but i got it near $100 cheaper, and yes have the 4bar map sensor.

The turbo its nice, not to big not to small. Fuel injectors i end up buying the Bosch Motorsports 750cc, because of things in the life i had a problem with my order and got 2 free fuel injectors, so i have them as spare.

The intercooler took me months to have it planed, i had this set up in a different way years ago, now i changed the radiator and the intercooler, wich i changed years ago with aftermarket parts.

Boost solenoid:

Boost Control Solenoid valve BCS MAC 35A-AAA-DDBA-1BA, turbo PWM EMS ECU | eBay

I got my MSIII 3,57 in DIYautotune.com and i might spend extra $600 in wire bundles and have the computer assambled etc,but honestly for me thats not a problem, i preffer to have someone with the skills and knowledge assambling the MS instead of paying a local electronic shop or do it myself, for me its not worth taking the risk, sounds weird but thats the way how things are were i am from.

Recently i just changed the oil filter base, i made my own filtering system with oil feed line to the turbo, the return goes directly to the oil pan.

The water line its quite an invention, the good thing its that i tested all this years ago and now i am improving everything, brand new parts and custom made.

I will post pictures of the advance of the project soon, i have been quite disconected in this forum for a while.

Attached there are some pics, any thoughts please let me know, i always appreciate the good comments and ideas.

are you going to run on stock internals?
the MS3 got few nice extras like anti-lag

Yes pretty much stock, i have all ARP bolts, custom engine head gasket design tested several times in the race track, original cam (in turbo you dont need º) i may replace in the future for forged pistons, so far the M102 show me to be pretty strong at 1 and 1.5 bar.

Anti lag needs to be develop on megasquirt, with this turbo ''disco potato'' the Lag is almost nothing, spools fast and charges at low RPM's, with a holset or td05-06 the lag will be more considerable.
