Noob to M30's
This guy used a 666 mani just like that on a stock m20.T_C_D wrote:That should be worth substantial HP where you want it! Great job.
Looks like it has a cam or something. You know how high rpm power completely dies on these engines normally.
I wonder if the m30 is more restrictive then the m20 though.

Those short runner manifolds are something else. I always wanted to try one but never made the step.
Assuming that dyno is an M20B25 with the short runner manifold, its missing a lot of midrange. The stock manifold is good for that, but sometimes you get a little more peak cylinder pressure than it can handle. Mine was making 380 rwtq from 4000 past 5000 RPM, with peak power of 384 rwhp at around 6400. I don't know if the short runner manifold at the same boost pressure would have made the car faster or not.

Alright had a few hours to play today. Pulled out the old tranny and got the C4 under the car.
Old twin disc setup next to the torque converter. That pilot bearing puller tools works like a dream.

Reverse pattern shifter, awkward moment putting it in but it's needed.

Here it is strapped down to the tranny jack. Couldn't imagine installing the tranny without it.

Here's a side by side next to the 5 speed, the C4 is similar in weight.

Twin plate not for sale, yet. It's coming together....
Ok, trans is in, cooler mounted.
Picked up the drive shaft today.
Trans cooler mounted were gas tank was.

Rear diff flange adapter to spicer 1310 U joint.

Ended up going with a billet trans yoke that had removable caps in order to install the driveshaft easily. It also has the beefier 1350 Ujoint. Drive shaft custom made with .083 thick, 3" tubing.


It's getting there, in the process of fabbing up the transmission mount.....
