MD-Machinst 72-1200 (Mattndew76)

Donated to the 1200 motor project today....

[izzo]

That was a very nice donation

Oh my

[Mattndew76]

It was this or I use my Paxton and that thing is huge.

I am slowly getting my head gasket design refined and will send it off to have it made for me.

[DRIVEN]

Does an A-motor even have enough torque to spin a Paxton? I can barely spin my dad's by hand. Apparently that a sign that they're still healthy.

Any idea what the turbo originally came from?

[Mattndew76]

I think the A12 could turn the Paxton.

No Idea what the turbo is off of. Check out the size difference though

Just joined the "chub club" what benefit is offered by the twin pulley head.
Will your kit work on both? Seems I have heard of people using the stock turbos from some of the Subaru models.
How will you incorporate the bike carbs into the big picture?
Just checked, still chubby.

Separate pulleys on the head give way to intake and exhaust timing adjustment with adjustable cam pulleys. With the single pulley it causes limited adjustments.

My kit will only work with the Z5 casting and will work with single and dual cam gears.

The bike carbs get a custom intake and a compression sealed air box for a blow through turbo setup.

I need to sneak my parts in between customer orders.

[Mattndew76]

Fits pretty good now.

[izzo]

oooooooooh damn. Thats nice. Looks tough as fuck and shiny. are you going to polish it out at all where the machine marks are or leave it?

[Mattndew76]

Im going to media blast it to a dull matte finish, anodize it red and call it good.

I like dull uniform finishes on the aluminum. Shiny give me acid re-flux.

Matt the steering box brace looks killer!

[DRIVEN]

I'll be curious about how noticeable the improvement is. I've seen these on plenty of Datsuns but always wondered if they were necessary. Be sure to update when you get it back on the road.

[Mattndew76]

I have heard on the OZ grape vine that its one of the better mods for the money.

I cant validate or confirm those claims but plan to reef on the 1200 a bit to find out how it feels off and on.

[Mattndew76]

Another Item I cant confirm but Im going to place on the 1200

[510freak]

The steering box brace is a good thing(especially if into autox)
Good bang for the money,The strut area is prone to flex(see the bolt area) it is a weak link for hard driving.

I have only heard praise about them on 510s. Like, you won't regret it.

This

Get someone to turn the wheel when parked,and watch the lower tower flex.
I would think any 10 series car would benefit from it,they all have similar design

[Mattndew76]

I am going to make some camber plates for the 1200 that also have strut brace locations should anyone want to add one to the kit.

[Mattndew76]

Test fit for the pulley is good. It's a little snug but doesn't need a pulley remover. Gotta put a key way in this thing.
