this baby is going to sinnggg i love the fact that your keeping it old school cool!!!!

[twin eng, twin turbs]

Hey thats really lookin great man, you should take it to the nats this year with the 8v engine if its still in there... I am saving for tuning on the turbs mk2 to get it down to the nats. Have you finished machining the torque plate up? Post up some pics of it!

wow this thread is starting to get wicked i cant wait to see the outcome.... mmm carb'd valver goodness

Awesome dude. And uh.. Finished? I haven't even started!! The billet is just sitting on the top of the block. When i get the chance, i'm going to put it on the Cincinnati CNC and machine it all in one set up so theres less jerking around. Either that, or i'll spot all the holes on the mill and wire cut the bore clearance holes out.. Mainly because i can. But also to save the alloy in the middle.

If you're wondering it's 5083 50mm thick. Graeme silk said 5083 was the go. 5083 has magnesium in it so i'd say the reason it's good for torque plates is that it has similar characteristics to cast aluminium, because cast aluminium usually has a high magnesium content.

Slightly more progress..

I gave the hatch to Brian Keegan today to repair the rust and get it ready for paint. So that should be done next week.

I finally got around to putting the other rear disc setup on this arvo. Everything went a treat (because the hoist was free.. ) and it only took about 15 mins.

I've decided not to worry about the proportioning valve. Considering i'll have larger brakes on the front etc it should be ok without it. I've decided if it poses a problem and i start locking the rears on corner entry etc i'll buy an adjustable proportioning valve and mount it in the engine bay.

Anyway, if it has a tendancy to lock the rears, i'll use it to my advantage and point it into the corners on the tail.. Should eliminate the problem of entry understeer!

Heres a pic of the back with the M3 style tails. Its the first time i've been able to take a picture of the back of the car since i put them on. Heh, due to the fact that the car has no interior at the moment, it kinda looks like an offroad vehicle..

[Jarred]

yea that looks nice!! What wheels have you got on? I've either forgotten what they are or not read them..

[GoLfMan]

sweet mate, all these mk1 buildups are motivating me to get mine done faster

[ausgolfer]

I'd advise you to put a proportioning valve in. I've driven a mk1 with G60 brakes on the front and 16v mk2 rear discs and no proportioning valve and it would almost spin under light braking loads, very tail happy.

i can 2nd that after locking up my rear disc's in my driveway dong about 20kph... and i had my toyo's on too

Ok, well looks like i'll be getting a proportioning valve then... My mate Mitch in sydney said to go to Motorsport Connections in seven hills. So i'll get down there in the next couple of weeks and chat to them about it.

Do run the valves - I'm also one that tried without them and it was dangerous to drive!! I used an inline bias adjuster, which was a good move, so I'd recommend doing that

Alright, looks like it's official that disc brake rear ends need a bias valve. I'll get on it as soon as possible.

PICS dammit man, i wanna see more of this engine build

Yeah, yeah! I haven't done much lately. I'll start on the toque plate at work tomorrow hopefully, went to Silky's yesterday with dad to pick up one of the 392 blocks that he put our 4 bolt mains on though, so gimme a sec and i'll upload a pic of that..
