I'm interested in how you did your rear brake setup. It's not a Massive setup? I'm looking for something very similar.

Yes, the rear brake hats and e-brake rings are from Massive but I made the caliper brackets myself. Rotors are Wilwood 11.75"x.81".

Thanks - do you know what model of Dynapro caliper you're using?

I could figure out the adapter brackets.

Also, how do you like the APEX wheels? I've been looking at these for autocross/track.

Thanks!

The rear calipers are The DynaPro Lug Mount (DP) forged billet caliper, the fronts are their DP6 caliper, I can dig up the piston sizing I used front and rear if you want. The APEX wheels are awesome...I've had many different wheels over the years and these are by far the best fitting (and looking) IMO. I did add additional inner fenderwell clearance in the front to increase the turning radius and I had rolled the lips both front and rear in the past, neither of which may be necessary but I did it anyway. I may even have a detailed and dimensionally correct drawing for the caliper brackets that you could use.

Holy fuck nuggets!

That's one serious m20! Must be a blast to drive, and it has to sound sick!

My only qualm with your set-up is the gearing. The 3.73 + 260 on a strong m20 is perfect, a 4.10 with your set-up is overkill IMO.

Find a 3.46 and you will enjoy a much nicer powerband! :up:

[UDelaware30]

loved the 4.10 with my m20 and maf conversion, this thing must rip.
Props on the proper tires and wheels and beautiful car all around.


now lets see some vids!

I actually would like to find and try a viscous 3.91 from an IX. I have had a 3.46 and a 3.73 installed but like the 4.10 the best so far, at least for how and where I drive. I think the 4.10 along with the larger diameter 235's is a nice compromise.

4.10s work great with a higher RPM powerband, and with 235's for sure. I've had cars with smogger gears in the past, no thanks..

Wow, fantastic engine build! I love it. Consider moving the battery to the trunk, you'll get better weight distribution.

performance #s?

[TexasTerp]

wow, that is a seriously built m20!! congrats man, that is truly inspiring!

[4bangerfury]

I like your ITB and engine management setup. Do you have a thread on any of the Megasquirt forums for building your ecu? I'm very intrigued by the coil-on-plug wasted spark setup. How difficult was that to figure out?

[digger]

do you have a dyno plot you can post up?

[gforce323i]

There is an old one posted around this forum somewhere, it's from the first time I had it on the rollers for my initial tune. This has evolved significantly since then so it will be on the dyno again this spring. Didnt I send this one to you specifically on another forum?

[nando]

I think you sent it to me

[durtyE30]

I'm in for videos, I need to see this thing in action.
