I have a question :D So since the engine mounts to the sub frame, which locates the wheels in the wheel wells. Did it end up working out so the motor will bolt in the factory mounts and be in the correct location in the engine bay? If so that is fucking awesome!!

Second question: What is the wheel mounting surface width from the MX stuff to datto stuff? From memory the rear of a 521 is 50" so the 520 must be some were around there.

I really really like the build, it fixes so many problems with the old datto trucks. Well I mean just by doing to front end stuff. Not that it looks easy or anything :D

I have a idea on the rear shock/coil-over problem, I might be running into the same problem as you,since I am using Miata suspension parts, with the limited height available between the lower "a" arm and the frame.

I have been thinking of using a push-rod and bell crank setup and putting the coil-overs horizontal between the frame rails , to keep the total rear end assy. as low as possible. Just a idea that I am throwing out there.

That is a good idea. I'll take some measurements this weekend. I'll also try and "mock up" the rear subframe assy and post some pics.

OK - It's Saturday morning and we have what looks like 2" of snow. I'm going through the mail and the new issue of Grassroots Motorsports Magazine just came (Dec. '08). If any of you guys get this check out page 152. They have a picture of my son Tommy in there. Pretty cool.

It's time to walk out to my shop and have some fun working on the MX520 :D I'll try and get some updated pics of what I get done. I don't know what that'll be, but who cares, I've got all winter to get it done! :P

Well - I got the Miata motor mounted. I had to cut out the firewall and most of the tunnel. I also got the front shock tops mounted. I left my camera at work. I'll get some pics up in the next few days. I'm tired.:cool:

Dang! Your family are all racing guy's no? Your father sounded like a really cool guy. :cool:

Really nice project man. Will the turbo miata engine fit this setup though? That would be a sweet upgrade in the future if one ever presents itself.
Keep it up!

I really wonder what I would of accomplished if I started to driving at a younger age. The next generation, its going to be diffrent. :cool:

This is my son Tommy. Yes he is 14 years old. He is the youngest nationally liscensed race car driver in the USA. Never before has a fourteen year old been allowed to compete at this level or in a National Championship Road Race! :eek:

This was taken at his first race in March '08. He was 14 years 2 months old.

Bob,

As I read the first page, I also thought that the bell crank may solve your clearence issues - Monte beat me to it. But I have seen this done on 620's and 720's using the stock Datsun rear axle.
I can't get a good look at your set up, so I'm not sure, but on the set ups that I have seen, the coil over unit mounted parelell to the frame rail, with the rear end of the coil over linked to a bell crank, whick was in turn mounted to the axle. Maybe this could get worked into your IRS, and save from cutting into the box, which wouldn't look so good.

Nice build, I'll watch this one.

Byron

Bob,

wow 14 years old, man I need to get on the ball with my own kids, Karting season is upon us here in norcal and I hope they enjoy it as much as i since I'm just a big overgrown kid myself LOL...

Love the project bob I was thinking to myself why am I the only one that has ever used the miata suspension as I loved how everything is on a cradle and is perfect for any scratch built project like yours. my project is not the truck buts its in a datsun roadster. wish I could figure out how to post pic

I need to finish up the motor mounts next. Then I'll mount the tail of the trannie. Then I'm going to graft the Miata floorpan / firewall / trans tunnel. This will prove to be a bit of a task, but should be too cool:D

I've decided to get the front half of the project pretty much done and then move to the back. So those of you interested in the rear end will have to wait. Although if you come up with any ideas or PICS of what to do this please post them!

I'll put up more as I get it.:)
