Re-spacing the ITBs

Today I had a few minutes to turn down the spacers for the throttle bodies on a lathe.
The three pairs each had to come closer by 150/1000 of an inch. from 3.15 to 3 inch spacing.

Cutting Fuel Rail

Cutting the fuel rail today.
6 holes with alternating 3 inch and 4.85 inch spacing

I didn't have a 17/32 ream as suggested to use by some authors of the megasquirt boards, so i ended up using a 3/8th end mill to cut the pocket to 0.531" diameter.

The injector fit is great, next task is to fix the GSXR-750 throttle body spacing.

Low Oil Pressure

Who ever says that oil and water don't mix well has obviously not tried to mix loose cotter pins and oil pumps.

This answers the question as to why we were seeing low oil pressure.

I am starting this blog to document our progress converting a 1968 E-type jaguar to electronic fuel injection using MegaSquirt (II V3). Currently the engine and (New JT5) transmission are back in the car after two years (pictures to come).

Here is the pile of parts I got off Ebay to start the conversion.

We started with an intake manifold from a late model series 3 xj6, (1986)

The Runners were cut down on the CNC machine, being careful to leave the water jacket part of the manifold intact so that I could re-use the water rail.

 New straight aluminum pipes were TIG welded in place.

The coolant rail had to be re-positioned (up) slightly to clear the straight pipes.









Here is a 36-1 Trigger Wheel and mounting spacer for the Crankshaft damper pulley. This will be the used for engine rpm and spark signals.
