cheers for that. the carlton used an AR25 autobox as well, so shouldn't be too much of an issue. am still unsure about whether the box needs any input from the engine, throttle position, manifold depression etc and how that would be got from the seh as it's on a manual atm. i think if i go ahead with the conversion i'll go the whole hog and stick the manual in as well, i presume the carlonator's g/box to centre bearing prop would fit no problem.
I ran a cav with an SEH and a couple with eco's and to be honest i didn't think there was much in it performance/economy wise. when my dad used to run the carlonator, he swore by the SEH, think he may be looking through rose tinted glasses, but he reckoned he got 40+mpg on a run. I also have a high lift cam for an SEH. decisions decisions.
I have made no progress at all with the omega. It's just sat on the drive since i got it. money's so unbelievably tight i can't even save up the 45 quid to get the boy to come out with his tech2. I'll be gutted if, after weeks of saving, he comes out and says that he can't find the problem. If that happens, the engine will be ripped out smashed up a bit with a sledgehammer (to make me feel better) and weighed in, then the trusty old SEH will go in.
Might have another look at it today, but tbh, it's a waste of time trying to figure out which bit of electronic wizardry is giving an incorrect signal just by looking at it and pulling plugs on and off.
as a footnote, I spent probably in the region of 400 on new sensors etc for my last ecotec engine in the space of the two years i had it, and spending on the SEH engine in the last fifteen years, zero, not a penny. well a new sump from the scrappy cos the original went porous, but my dad bought that. oh, and a couple of fuel pump relays, but that doesn't count (turned out to be a dodgy pump)
