Hmm,
I wondered about doing the same thing, my concern was easily making something strong enough that didn't force the "extension" away from the block to much.
I know there's not going to be a LOT of load on this, but is this in street car, or one of your more abused machines?

I thought it was "that car". Good to know! I'll probabely make something similar then.
Cheers

So a decent bit of time in this weekend, All the suspension sub frames are back in, the rear diff and shafts too. The engine harness is back in place, as are a few controls, and bits under the hood. The dash was in for a bit, but I pulled it back out at the end of the day today to deal with a few things behind it again. We're getting there! I think the Orange paint on the diff is good for 2 seconds per stage mile!!! Oh and sorry the pics are bit um... cell phoneish.

For those that want to swap to second gen hubs, brakes etc... after pulling apart 4 various broken front half shafts... I found no difference in the splines between the first and second gen shafts. That means you can take a second gen axle (outboard cv joint) and mate it to the longer first gen shaft no problem.
Once I get some new boots I'll post some pics of the process maybe as a sticky in one of the other sections. It's a very simple job, and means you don't need to worry about fabbing up a bracket for the second gen shaft extension. I may do the full swap one the motor is ba k in the car, but hollandjusty's comment about transmission width caused me to want a backup plan. The last thing I need is to have the shaft binding somewhere in the suspension travel arc...

You can mount gen 2 axles to a gen 1 gearbox, but not the other way around.. The "axle stumps" (?) of a gen 1 are shorter then those of a gen 2. When (trying to) mount(ing) gen 1 axles to a gen 2 gearbox you can't secure the axle. (If you try to hard to fit them you'l demolish you inner CV boots ) Ah sorry I didn't read your posts too well.. I'm 90% sure a gen2 CV boot is bigger then a gen1 boot. But you're right about the splines those are all the same

Progress report... Dash in Engine in Fuel tank in Drive shaft in Shift mechanism modified for short throw and mounted New fuel pump bracket fabricated (rock proof!) and test fitted A few grainy pics... Stainless steel bush replaces rubber bush in shifter Extension on shift lever moves linkage up for more throw, now about 5 inches between 1st and 2nd instead of 12.... Combo of raised floor and lowered bracket provides clearance for the extended throw, oh and this is a second gen shifter set up in the first gen car... Fab'd fuel pump mount Mounted to reinforced rocker (from the rust repairs), That's the fuel tank to the right, we're looking forward Parking brake cable adjuster was rusted out... replaced with beefier rust proof adjuster Suspension is next... Plus the possibilities of a lumpy cam and still hoping to have the triple carb set-up figured out soon! That's all for now.

Looking good. My project is coming along nicely also.

So... Little Justy ran for the first time in 6 years! Pretty rough, and not for long as the rad's not in yet, but 40 lbs of oil pressure at 2500 rpm. All the electrics are in and those that need to work are working... we have fully functioning lights and fuel pumps and all that jazz. Most of the important stuff (ignition, fuel pump, fan, lights, odo) has a back-up circuit we can throw if need be. Still a few issues to sort, but pretty much just bolt on things now.

So the final countdown is on... The car runs, drives, stops and turns... Now we're working on the fun bits. The big cam is in, sound like a Harley at idle (cept sounds like the idle jets are blocked from sitting for years... so it barely idles to start with). However, the triple carb set-up is planned to go in tonight! Should fire it up later tonight. Pines is Saturday... lot of work and testing to do in the next few days. Here's some pics. Won't have much time to post again between now and Saturday. Matt

Major, major boner. This is the ultimate Justy as I've always imagined it.

K,
Real quick, headed out to tune a bit...
It runs! It makes the most horrifically beautiful air sucking sound! Idles away nicely, better on the triple carbs then the single, but I think that's cause that old carb needed a rebuild/cleaning.
No idea on mixture yet. Need to do some pulls tonight and find out. No dyno, no wideband 02 sensor, so I guess I'll do it the old fashioned way... Cept the alley isn't long enough!
Cam is from Delta Cams in Tacoma. Decent to deal with, helped me out a bit, but I think just did the grind they had on hand. More duration, bit more lift. Will post the specs sometime soon (after Pines)
Yep, we're number 40, but not sure our seeded number. We'll be the lowest Hp Open Class car I'll bet!
but fun none the less!

How'd she blow? The results are vague...

Well............
She didn't blow, but she didn't go.
Long story short...
We left for the rally on Thurs, knowing we still needed to tune more. It ran great up to about 1/2 throttle, then bogged out. I had hoped to find jets on our way to the rally, but we didn't. We made some strategy errors on Friday, doing some recce and getting the car ready for tech, when we should've just spent the day tuning. It flew through tech with flying colours!
Friday afternoon tried to tune, not much luck, Dan Sprongle came over at 6:00 pm to give us a hand. We didn't have time to find jets, but we tried everything else. I dropped the needles all the way (earlier) we ran 30 degrees and more of advance, tried shutting down the fuel pump to cut pressure, ran colder plugs, pulled the air box off, yadda yadda yadda.
The car made great power potential under 1/3 throttle, so there's hope, but it was too hard to drive when the diff between idling, running and bogging was about 1/8 inch of pedal throw...
So at 8:00 pm we made the decision to swap back to the stock carb (which we knew wasn't working well either...). Unfortunately that involves swapping the head as the triple carbs run on a FI head... So at 1:00 am after a trouble shooting many problems on the stock carb, we had a running rally car.
We started the car in the morning and it ran like $h!t... but we'd already paid our money and thought, lets go out and see what happens, maybe at first service we can get it better...
First stage was so down on power I didn't think we'd make slow time! We stopped on transit and debated going to 2nd stage. Decided screw it, we're done, we'll go back to service. I fired the car back up and suddenly it ran well! Okay we're 15 minutes late, but lets go (still had another 15 before we maxed out.)!
By the time we got to the start of the second stage it was running poorly again. We got passed twice on A2!!!! I've never been passed before, that was sad.
Pulled up to the finish of A2, pushed in the clutch and BANG the cable snapped. WTF.
Limped back to service cut the cable housing in half, tried to link the cables together, left service with barely time to make the start of A3 (should have thrown in the towel...). But on transit the clutch was slipping from the poor rig. I stopped to adjust and the with a minute or 2 the 000 car came up and shut us down.
Moral,
More prep, more time, and more tuning needed.
Good news:
I only needed the brakes twice, both on downhill sections in A2, but the big brakes swap and the braided lines are awesome!
Even my rigged suspension is working "good 'nuff" for now. The car feels way better and more solid with all the shell work and stiffening.
So now I need to build a motor that works.
Next year.
There'll be some pics so I'll post links when they are up.
Now I have to get back to the month of work I'm behind on because of all this!

That's a good story to read, but a painful one to tell, I'm sure.
Glad to hear you're wiser as a result. Jeez Matt, everyone knows to pack an extra clutch cable!
