I'm well into a Megasquirt conversion and I have had a 1.8 Escort engine for SVA and now have a 2003 ST170 VVT blacktop in.
Both these ran on carbs with Megajolt previously and the 1.8 with 2L cams gave 155bhp on the rollers. ST VVT engine gave 166 but was running well lean at WOT. Oh, and the 1.8 once setup gave me 40mpg. (but not on a track day!)
Points for the conversion, Escort sumps are lower than Mondeo ones. Escort water pump runs the right way for a triangular belt set up, all others need an idler... heres mine..
For my new EFI conversion I'm using early GSXR 750 TB's and am using the original Ford injector/fuel rail set up. I welded bosses into the manifold so they pintr down the port in the same position as original.
Only other thing required for mating to the type 9 is dohc or CVH Sierra starter motor.
This was my old carb manifold...
And with carbs running Megajolt (with an EDIS unit)
Have look round my blog, not comprehensive but some pics ad descriptions are there. If in doubt, ask!
Good luck,
Steve
