This allows us to shim the throwout arm pivot to the correct height for the proper motion ratio.
The shims are placed under the pivot and the pivot screws into an existing hole.
Here is the pivot, shimmed and in place.
The new throwout bearing and sleeve is placed on the new throwout arm.
The throwout assembly is put into place. Does this look familiar like the good old days of throwout bearings?
Now the bracket that holds the slave cylinder is attached to the transmission.

Yaaaasssssss!! Loving these updates!! Since IAT’s are so susceptible to heatsoak in this car, do you think moving the mafs or possible running a different IAT sensor just after those filters would be beneficial?
No, not with the ability to tune the ECU.
interesting. so with uprev/ecutek etc. you can disregard the scaling or just tune to not pull so much timing?
you can change the MAF tables.

Surprised you didnt go for long tube headers since you are ditching the cats anyway? Well documented power and SOUND improvements to be had there. Also those intakes are very long, no detriment to power having the inlet tract so long?
We know long tube headers are better for power production, but that’s not what the car owner wanted. He wanted to be able to put the cats back for street use.
Street use, but un-sprung hub. What a mashup! You mention un-spung hub being better for synchros. Why do you figure that?
I guess it’s because the disc, which is still connected to the input shaft via splines is lighter and can change rotational speed easier with less inertia. Got it.
Lighter and less inertia.
Did you guys notice a lot more NVH from the gearbox with the unsprung centre?
I did a CD009 conversion on my SR20 and initially had an unsprung twin plate. Due to the relatively large backlash in the gearbox the off acceleration chattering of the gears was insanely loud. Changed to a sprung centre and majority of the noise was gone.
I know about the noise because my twin disk solid hub clutch on my Z is awful in this regard. In this case it isnt so bad.
oh…
Did you notch the bumper beam, and then box it back in? It looks like it, or Howard is just darn pure magic. It wasn’t called out in the article.
Yes it was…and Howard is most definitely the man!
thanks for the reply Mike cheers
