Fitting the Mighty S10 clutch

I had always wanted to fit a bigger clutch, just to be on the safe side. So when i had the chance to get an S10 clutch from Opel GT Source in the US, i took the chance a bought one (I was lucky enough to have someone bring it over from the US as the postage would have been more than the clutch!) and thought one day i will fit it to the car. But as i had to have the engine out to sort out the piston i thought now was the perfect time. Using the Monza flywheel…

Dipstick alternative option

Not wanting to have to drill the block to locate the dipstick hole where it should be for the manta in the block, i did a bit of searching and found the the US Ford 73L V8 Diesel has an oil pan dipstick!! So after a bit of measuring and checking i reckoned that this would be just what i needed. So i ordered one on ebay and when it arrived measured it and bought a metal hole punch to cut a nice clean hole and as i has a spare oil pan i thought i would give it a…

Fitting Pistons

Last time i built the engine up i used one of those pesky band type piston ring clamps and it wasn’t the greatest thing for fitting them. So this time i did a bit of reading and came across these ring compressor sleeves from Wiseco. They start off wider and taper to the same size as the piston bore. So i bought one to try it out and they are Amazing. No hitting the piston top with a hammer end or something like this. These you can just push in with your fingers as unlike the band type that you…

Alpha Webcon system fitted to Opel A Series Manta

Getting closer!

Ok, so i was a little bit of course with the thought that the injectors were not firing!! After borrowing a friends tester for the injectors and the fuel pressure it turns out the injectors are firing and the fuel pressure is fine at 2.5 bar also a nice bit of a spark from the plugs! You can have a little look at a few videos of the testing here. So another email to webcon and they think the Throttle Position sensor reading is to low and i need to increase this? The old A series did always suffer a…

Opel Manta A Series 1.9 engine rebuild takes shape!

As the bottom end of the engine is now nearly complete, i have started working on getting the head fitted up and ready to go. As the rebuilt 1.9 engine will be running twin weber alpha throttle bodies with full webcon injection its not turning out to be a straight forward job!! I have the throttle bodies all bolted on and the injectors in so its now just working out how to get the fuel lines, cold start valve and any other bits needed for the injection all fitted on. And as the Manta A series engine has exhaust and…
