As for coil dwell, go with what the coil manufacturer recommends, not what MegaSquirt recommends. I used an aftermarket coil on our Jeep. Bench testing the coil, I got optimal spark at around 2.1 ms dwell (way less than your 3.5 ms). The Jeep ECU outputs a stock 2.8 ms. The additional dwell...

I suppose not much different here. Fits with AC, PS, & PB.

If I remember correctly, the 2 pick-ups are out of phase of each other. What you might have to do is try one and see where your actual timing comes in at. Try the second. Pick the one that puts you closest to where you need to be. I looked up the MSD box, but didn't download instructions...

I never used the Victor MLS, but with the Cometic MLS the 2.2 turbo crowd has been getting cars into the 9's with absolutely insane boost (over 30 psi). Mike

Diesel turbos weren't designed for vacuum. Using one on a gas engine in a blow-thru fashion shouldn't create issues, so long as a blow-off valve is used. The blow-off valve will keep excessive pressure from blowing out the seals from the inside. Mike

I searched for a turbo map for your turbo. Here is some of the stuff I found: http://www.dsmtuners.com/forums/newbie-forum/421850-diesel-rednecks-compressor-maps-he351ve-related.html http://www.fiero.nl/forum/Forum2/HTML/120491.html This should give you some ideas. Mike

I also favor the Cometic MLS head gaskets. They work about as good as O-ringing. Mike

On the 2.2 heads, the dimpled area is a "dead zone". The dimples act like golf ball dimples and induce activity to help keep fuel from separating. Mike

If you are using closed chamber heads, simply radiusing the sharp edges of the deck could dramatically improve the engine's tolerance to boost. Part of it comes from the reduction in compression ratio from the material removed, and part comes from the improved combustion characteristics of the...

If you are connecting your FPR to manifold, is it possible that under vacuum you are getting less than 5 psi? Don't know the product. Mike

One of the tricks is to run pipe under the engine to the opposite side and mount the turbos. Another trick is to put the exhaust manifolds on back wards and tap the flange in the front. If you had a big block, you could mount the manifolds up side down. Building a manifold could be simple...

I'm curious about how you're referencing fuel pressure to boost. You need to maintain 4-7 psi above boost pressure for the carb to function. I did an article on Allpar a couple years ago that covered referencing the breather port on the fuel pump to above-carb boost (See the Holler Help...
