Finishing the brakes

So i now have all the parts needed to finish off the front brakes. Got the last couple of goodridge fittings needed to connect to the Wilwood callipers and got a couple of spacers to space the calliper out the 3mm to get it centrally aligned with the disc. This was a better option as the other one was to have 3mm machined off of the custom adaptors. So a quick test fit tonight and then all i need to do is get some thread lock and cut the brake hose to length and fit it all up. A little job for…

An early Christmas prezzie

So a little early Christmas prezzie for me and the last set of bits i need to complete the A series. So after Christmas its time to get back on the build. A big thanks to Nick in the Opel club for bringing the parts over and to Gil at Opel GT Source for sorting out the delivery. So i now have a chevy S10 clutch kit and matched Monza flywheel for the A all the way from Opel GT Source. This will handle all the power from the engine no problem as the clutch cover is a 6 bolt…

Hydraulic clutch fitting on the Opel manta A series

I have always hated the clutch cable crossing over the engine on the a series and wanted to get rid of it and fit a hydraulic clutch, but have found it hard to find any info on someone fitting one. So i did a google and looked at other cars using the wilwood pull cylinder to get some ideas. I decided on an external slave cylinder as its such a pain to drop the 5 speed gearbox on the A if i did have issues. So a plan was hatched. i decided a bracked that bolted to the engine and…

BMW Halo Angel Eyes now all working in the Manta A

Once i had figured out the A series wiriring it was a quoick and simple job to get the lights all working. They work just as the A series ones use to. I cant decide if i should hook up the Halo’s to run as soon as the ignition is turned on so they are like running lights? It should be as easy as swapping a feed out from the ignition to the light switch. But as i have a few other more important things to sort out first so i will leave them as they are and add this to…

BMW Projector Halo Lights by DEPO

I thought i would post this for anyone fitting the BMW E30 Halo projector lights from DEPO . When you get the kit you get a loom to hook up the new Halo part but not for the rest of the kit. So unless you are fitting it to a BMW you will need the plugs for the main and dipped lights. It took me a little while to track down part numbers.Lots of BMW dealers in the US seem to stock them, but i had no luck with any UK ones showing, so it was off to my local BMW…
