Thanks. It does indeed click and feels pretty positive. Before I added a center support, the rod would flex and hit the edge of the hole in the pan. I added a sway bar bushing but it was causing the linkage to bind there, because my mount for the bushing was deflecting and allowing it to tilt, if that makes sense. I plan to try to strengthen the mount to see if that helps.

Also, there is not enough ground clearance at the rear. The linkage is the lowest thing at the rear of the car by about 3 inches. I plan to remake the end of the aluminum shaft so it steps up. I think I can tuck it up pretty tight, because the Acura shift shaft only needs to rotate maybe 20 degrees total. I may wait until the car is running for this.

I plan to start on clutch linkage next.

Also, I plan to start gathering more items necessary to splice my axles. The last time I did this I got some 1.5 inch round mild steel bar stock and made couplers on a lathe. I welded it all up, put them on V blocks, tested them with a dial indicator and trued them in an H press.

I don't have a lathe any more so I plan to go hillbilly this time. I bought some cromoly tubing that is 1.125 ID and 1.5 OD. The Porsche shafts fit in with a little play. The Acura shafts are too big at about 1.1875 inches. I plan to buy a drill bit (priced them for about $25) that will allow an interference fit.I plan to make circular shims out of sheet metal for the Porsche side. I will drill lateral holes and rosette weld and circular weld the shafts together, then try to true them up. I did the calculations and these tubes should be as strong as the Acura shafts.

I have made lots of drive shafts for RWD cars. If I can get within 0.030" out of round on those I'm happy. For this I hope to be closer to .010".

Tell me about your swap or post a link. It looks like yours is transverse?

I started working on the clutch linkage today. Right now it looks way easier than I thought. I drilled a hole through the trans near the bell housing. I am passing a rod with a heim joint though this hole. I plan to weld a bolt to the clutch fork arm to attach to the heim joint. Then connect that rod to the VW cable after running it under a pulley under the driverís side CV output.

Your clutch linkage sounds simple and elegant. I run a heavy duty cable with grease fittings that's sourced from a trucking outfit. There is a shallow 'S bend' running past the engine (where I positioned a fixed mount holding the housing) It made a big difference, a more precise feel, over the stock cable, which felt like it was stretching a bit and finally came apart, likely due to wear at the 'bend. But I'm running a 10" Ford Truck three finger clutch.

Thanks. I decided to extend the cable end with some 1/2Ē tubing instead of the roller. I got it together and stepped on the pedal and it feels nice and smooth and like a clutch pedal with that over center feel. I wonít know for sure if it works until itís running.

Yes it's a transverse setup. Think of it like a Chevy Cobalt. Works pretty good. Looking forward to seeing more progress on yours.

Your car is sweet. Now that you posted the link I realize that I came across it months ago while initially researching my project. Itís really cool. I might get some wide glass rear fenders too. But I like the big tail lights (although I realize most people donít) so I want to keep them.

I tidied up a few little things today. Here are some More pictures, including a view of the top of the engine through the back window. Iím exploring the idea of putting a glass cover over it so you can see the pretty engine, like some Italian exotics. Incidentally, this engine is a cousin to the 1st gen NSX V6, which is a C32A vs this C32B. Although they share basic architecture such as a 90 degree layout (vs the later 60 degree J series) the NSX version makes 260-290hp with VTEC as opposed to my 230hp non VTEC engine. Somewhat ironically, the NSX engine is transverse.

I know you said you want to put some sort of engine cover on it and I do have an idea. The engine cover from a NSX just happen to be about the right size. Thats what I used for mine but I think it would fit your build better seeing that you are using an Acura power plant.

Nice job! You plan of forming up a trick looking cover? Personally, I think the large tail lights balance out the look.

Thanks!
My body mods to cars usually end up looking stupid, so I don't think I'll make a cover.

I do think I'll try to make the exhaust come out of the two stock cutouts. I was planning a low boost turbo setup, but I think I'll save that for later.

'Rear cover' wise, how about a round metal two gallon or so can, on its' side with open 'top' toward/over the transaxle? Cut away at angle to fit rear apron so bottom faces rear with a, 'tah dah,' VW emblem in center. Attach with proper amount of duct tape.......kidding . Fit the deck lid as required. The cover will mimic the big round tail lights.

Maybe! Iím not sure what to do about the deck lid yet. There may not be as much interference as it appears. The one that came with the car is pretty much perfect and orange. If I could find a way to keep it intact that would be nice

Hmmm. Okay, the Formula look is appealing, with the bare alloy lending an exotic touch. Are you planning on bumpers, nerf bars, or?

Iím planning to go with the stock bumpers. I would go 68-73 non shock absorbing to save weight but I think itís a good idea to protect that trans.

Unless you are planning on beefing up the stock bumpers and the body to help, there will be no decent protection offered by the factory bumpers of any year. the shock mounts actually helped a little before the crumbling of the bumpers happened, but there were none that really did much buying a "barely moving" scenario, with little to no force induced. You can almost bend the factory 74 bumpers with your muscle power... almost.

Just my 2 cents worth though - I love the build. I love the factory bumper application (in my mind it will look great), I just don't think it will offer anything close to protection for that outcropping of mechanical parts.
