Looks good, keep going

 

got my donor 12a out and will be tearing it down over the next few weeks
fingers crossed that the housings are mint

 

Modified 73 rx2 housings to work with 85 plates fun experiment

 

Is there a big change in tension bolt placing?

 

1/4" at the most.

 

I tried putting my 83 rx7 wheels on yesterday and it appears they are rubbing on the stearing knuckle.Do I have to run a spacer would like to use these wheels as they have brand new Tyre ' s on them

 

I tried some rx7 wheels at one point and I did have to run a spacer so it clears.might be cause the offset.

 

could anyone tell me how thick of a spacer i would need?

 

Buy a handful of washers and stack them up on the hub over the stud equally one by one until you get clearance. This will give you an idea of what thickness you need. I'd guess about a 1/4 spacer. This only works if you've done a wheel stud conversion. It's near impossible to get the washers to stay and line up the rim and those silly original lug bolts.

 

thanks ozzy i had got advised to get 1/4 spacers.Waiting on them to arrive.

today i pulled the rx2 transmission and had a bit of a comparison

shifter location from bell housing
rx2 26"
fb 31 3/4"

transmission mount center from bell housing
rx2 20"
fb 21 1/2"
also the fb yoke fits the rx2 transmission and messure the same length at 30 1/2" iirc

so i need to shorten the shifter 5 3/4" and move the mount 1 1/2" forward should be easey.

 

working on building a half bridge.
ports are not finished but are work in progress

 

offset...

old school (2's, 3's and 4's) are +25

later model (such as FC and i think FD) is +38

that's millimetres..

also, why a half bridge? you're already fighting with one arm tied in having under 1.2 litres to play with.

 

small update slow progress.

shortened the shifter


s6 rotors milled to 12a specs with 3 window bearings


extra rotor clearance

 

hand lapping


front cover polished


exhaust porting "rough in" to match s3 opening timing and match the sleeve




more to come soon..

 

Which rotor housings did you end up using?

 

I am going to use the 73 rotor housings and will use carbon apex seals.

 

Just so I have this clear... It says above the picture of the stationery gears "s6 rotors milled to 12a specs with 3 window bearings"

So your using FD rotors milled down to 12a width?

 

^ I believe he meant to say the stationary gears

 

Yes I meant stationary gears. Sorry for the confusion.

 

I corrected my bridge to a more functional size and fly cut the housing to increase flow.

 

Ok... I got confused there, lol

 

looking nice..

 

Painted the irons close to a colour I would like to paint the rx2.

 

That looks fun.

 

Great color for the irons. That would look FINE on a 2
