M20B29 w/ Triple Webers into my '71 2002

[SkiFree]

Nice looking Z, always like those car.


Update Me/IE

Got the oil pan baffle prototype finished up and nearly ready to go. Been wanting to make these for a while now to use in conjunction with the windage tray. Hopefully have them tumbled and up on the site in the next week or so.

great build ... looking forward to the updates.

Sorry not many updates. Been finding out that there needs to be more hours in a day with full time @ IE, full time @ school, and a family (7 month old son loves sitting in the 2002).


Groma/Mano update ---- will be getting back to the Groma car next week, plan is to now have a completely shaved bay, pics to follow.

Me/IE update
snapped a better shot of the car, not bad for original paint.


---- turning focus to more immediate problems than the engine. Am rebuilding the front and rear subframes/suspension. List as follows....

FRONT subframe -- weekend warrior build (not overkill on street but certainly stiffer than stock.)
- IE Driver's side motor mount weld in plate
- IE front urethane bushing kit (inner and outer control arm bushings, radius rod bushings)
- OEM idler arm bushings
- IE urethane steering coupler
- OEM tie rods and track rods
- Rebuilt steering box
- Bilstein Sport Shocks
- IE stage 2 springs
- OEM lower ball joints
- GROMA reinforced lower control arms
- IE 22mm front swaybar DropCenter (clears M20 oil pan)

The steering box I had ready to go was snagged for a customer so what better opportunity to learn how to rebuild one myself. The 2002 steering box mechanism simply consists of a steel roller shaft mated to a worm gear, these parts are now NLA so if your gears are pitted/ground (see below) you might want to consider getting a rebuilt box (or buying a couple other used boxes in hopes of piecing together a good one)

Steering box diagram via RealOEM, a little simpler then that power steering.


Notice the flat spot on the inside of the right roller shaft, this would indicate it would make a good paperweight!


Notice the grinding wear on the left worm gear, also good for stacks of papers.

Where is the thread tool that will slap me in the face when something this amazing is going on in R3V... WHERE!!?

Glad I'm to par with it now at least.

This build interests me a great deal.

So keep going and looking forward to updates.

So weber 40's? Im guessing?

Or bigger? I was at the vintage races ad saw Lotus twin cams with dual weber 50's... astonished I got to talking and they actually just had venturis (or whatever they are called) in them to make them smaller

Yeah, going with 40's as the goal is to keep the streetable. 50's would be madness, smaller venturis do make sense though.

^ Thanks for those side shots, just what I was looking for. I called Pierce the other day and it seems that they indeed no longer carry the DCOE manifold, they do however, still sell the IDF manifold.

Progress has been a little slow but hopefully have some updates this week.

Could you send me a side profile picture of yours?

Sure, hear are a couple different views.

[SkiFree]

LJ851 - Thanks for the offer but I'm too deep into the solidworks stuff to stop now. I'll also be looking to raise up the weber side simular to the one you have.

The one you have looks very similar to the ones Pierce manifolds used to offer (NLA according to their online catalog http://www.piercemanifolds.com/category_s/200.htm )

Could you send me a side profile picture of yours?

[LJ851]

There are no markings on the manifold. The guy i bought it from said the setup came off a Korman stroker 2.7 or 2.8 i cant remember. It's very nicely made and one piece.

[SkiFree]

Triple sidedraft manifolds designed for a 323 are raised up to clear the distributor, I could probably be talked out of the one i have if someone wants it.

The manifold you speak of, is it the Pierce Manifolds piece for IDF downdrafts or one I'm not aware of?

[drutt23]

^^ haha perfect, Cropping one for my little picture.

drutt23 - Thanks for the input, I've seen the type of setup you're talking about. I would need to run Weber IDF downdraft style carbs and then that would mean no the ability to use the manifold for ITB's.

Saw this IDF setup on an Alpina E21 M20 in Chile http://www.youtube.com/watch?v=78MrlRvrM9o - have to endure the bad music though.

Ok now I understand. Thanks for the clarification! :D

awesome project you got goin!!!!
