Outer Limits 4x4 Board

I have a set of Isky 202-hy's, cool. Are you sure the 9.35 to 1 is with the head gasket. I find it convenient/strange that Rover 3.9/4.0/4.6 all have the 9.35 to 1 ratio engines(even when they changed from steel to composite head gasket). The heads are the same, so do you think when the designed the ...

The 9.35 to 1, is that with the composite head gasket? The machine shop I went to said that all Rover heads are warped at least .006-.008 and he goes up to .020. But I know I'll have to shim the rocker post or have a cam's base circle changed. I' ve heard that if you order a custom ground cam it ...

Just had block and heads checked. The heads are warped .016-.018" and the block in under.002" and no dropped/moved sleeves. I'm having the heads pressure tested $70 usa. If good I will have them shaved and valve job. Tim

If 1 cylinder had anti-freeze I would think dropped liner, but the pass side of engine (all 4 cylinders) had anti-freeze. What is the normal amount the heads should be warped? There is a "black box" for the EDIS it's called Megajolt. I'm leaning towards Megasquirt, I just wish a Ford EEC-IV would ...

I just removed the heads from a 4.6 that I was given and there was anti-freeze in all pass side cylinders. The engine was removed for loss of compression. The waterpump shaft came off while driving on highway. I was told the driver pulled over as soon as it happend. The drivers side is fine. When I ...

I would use the dizzy out of the 3.9, but would have to purchase front cover, cam, and lifters. I can buy all the EDIS and Megasquirt parts for less.

You're right, I'm in the US. Its just most US rover forums are limited to there Rover egos, and would/will not change from Rover electronics. So I come here for "open" opinions. I would like to install EDIS. The research I have done so far leads me to Megasquirt. I believe it will be alot easier to ...

Its more than I want it black. I would love the lose the dizzy. I think I want to use the EDIS setup.

I just picked up my newzed 4.6, and I like the black intake(GEMS). I think I have 5 options. 1- use the 4.6 intake w/3.9 front cover(check or change water and fuel temp sensors) and change cam 2- use 4.6 intake w/3.9"B" front cover same as #1 plus buy Disco ancillaries 3- use 4.6 intake, front cover ...
