Where are the directions for this thing??!







If you look at the first pic you can see where the connector was digging into the MS3x.

What are you running for tuning? Im trying to figure out a megasquirt set up v3 for my s50 turbo i have been working on

My buddy, Snapundersteer, is helping me out a ton. I have very limited knowledge of MS3X at the moment. What help do you need?

Can't wait to see the results.

Do you have any input on how to straighten out the manifold flange?

[DrLeadFoot]

Just talked to the machines and my #2 valve seal was turned inside out causing oil to leak in the #2 seal. I was super worried that it my be piston rings.

He also checked my blunt tech manifold for straightness and it was off .060 and he doesn't have the right jig to mill it down.

My head has been milled down to the maximum. 5.500" total thickness. It's a new head if this one goes... Come on Megasquirt!

All new valve seals have been installed and no valves were bent!

Me too! I'm also going megasquirt 3x so I can finally get a proper tune. It's in the mail.

I'll document the process as well as I can

I wish I had done this when I had my head out. Didn't have the guts to grind the ports though.
I would just go with oem gaskets.

Gotcha, that makes sense. I have those exact "metal" grinding heads, and I'll probably pick up a set of the "sand paper thingys".

Hahaha ohhh I can imagine... the music playing, getting all up in there with your fingers.... were you also working by candlelight?

My wife kept on walking in on me. It got awkward after the 4th time...

I basically port matched the gasket first then grinded the sides down to make them straight with the insides of the runners. You need to get the right dies. I paid $100 total for both of these snap-on grinders and borrowed the sand paper thingy which really finished nicely.

It will make more sense once you get in there and grind. I felt for similarities and differences with my fingers and listened to classic R&B pandora. It got pretty romantical...

Are you following any sort of principle when doing this porting, or is it more of a gasket matching? I ask because I'll probably be pulling the head off my e36 w/AA stage 2 S/C and longtube headers and this would be a nice additional project to do while it's apart. Plus I already have all the tools and bits.

Either way, looks good!!

Got the exhaust side of the head ported out a ton.

In a couple of days I'll get the head back and go from there. I'll be ordering Megasquirt 3 soon and see how all that stuff works...here goes nothing!

Stock width:


The final width was 49mm. I still had a little of work to do on this one.

This is awesome!! Small world!

A friend of mine here in LA is from Milwaukee and was visiting his family a few weeks ago and randomly saw your car in a parking lot. He snapped some pictures and sent them to me. I only saw the rear photo at first and immediately guessed s52 turbo - and I was right! Then I wondered if you were on the forums, and lo and behold, a month later I randomly stumble upon it!!

Sick build, very impressive and quality work. Subbed for more progress and a retune when you get the headgasket sorted!

I'll keep an eye on this as inspiration for my own!!
