Re: DW's (new?) Sierra 3dr YB race car

After a couple of days of tinkering the YB now looks like this.
Virtually everything is bolted in apart from the alternator and exhaust. Will bolt turbo on once its all in the car









Now has all new breathers, G19 plenum, 'dizzyless' dizzy, turbo oil feed, new dipstick, alternator drop bracket, turbo damper etc..

Next step is to drop it in and get the plumbing finished off

Re: DW's (new?) Sierra 3dr YB race car

got hold of another 3 door rear beam. The arms etc should be useful as spares but the beam itself is supposedly modified by graham hathaway with most of the holes moved for better geometry. Time will tell but i wont swap the beam until the diff comes out for a new ratio later in the year.

that beam is my spec and modified for me on graham hatherways. I would swop it straight away the difference it make is quite a bit david it will help with wheel spin ,tramping when coming out of corners and the hadling is brilliant ,just a little tip its worth swopping

Re: DW's (new?) Sierra 3dr YB race car

More progress this week. After having had a twin plate AP clutch so kindly donated to the cause by Graham I bought a new pair of plates from burtons and assembled everything ready to go on.
Everything went together nicely to with some new bolts and a type 9 input shaft I got everything fitted to the engine.
I have a good race release bearing, new modified cable so hopefully thats the clutch sorted







Also replaced knackered gearbox mount with a vibra technics one. Hopefully gearbox is all ready too

Some more pics from yesterdays effort, even gave the car a quick wash once it was all done









Still got to fit gearbox and starter, clutch cable and throttle cable (which I'm gonna have to modify or replace)

Thanks Ian, yeah progress has been pretty good thanks to mocking everything up prior to getting the engine. As usual though the obvious stuff has gone in really quick and it will be the little details that cause holdups, but so far so good

Not a deadline as such, just asap really. Wanna do a whole test day once its mapped just to check everything as so much is new now.
Not getting enough time on it so progress isn't as rapid as I'd like

Re: DW's (new?) Sierra 3dr YB race car

I know that feeling Dave! Everything you're doing looks the business - not long now...
