Well, gonna pull the supercharger.
The belt drive needs work(already shredding its first belt) and I don't have the time to work on it  right now. So it will go back to being NA for a bit.

That's too bad, going from power to no power's gotta be a bummer........

[truckinwagen]

yeah, well, it will be going back on soon.

it just needs some work, a little refinement, but I am spending weekends in Homer for a while, so it will have to wait.

well, I took off the supercharger, the box on top of the car, I took all the tools and spare parts out of the trunk and gave it a good once over with the pressure washer.

then I drove 220 miles to Homer(sitting in Homer right now) and it got 33MPG on the drive down.

not too bad, even with winter fuel, and hard rolling winter tires.
probably will get 40 or so in the summer on that drive.

happy to say that nothing went wrong on the drive down, and dont expect anything to go wrong on the way back up.

the little rig is in alot better shape than I thought...

Great thread, that sc is epic.

[truckinwagen]

well, alternator ate itself... ...Again!

the regulator failed, causing it to overcharge and burn the windings, so it is being rebuilt locally.
trouble is that the regulator is special, and NLA.
so it is being rebuilt as a one wire alt(not my first choice, but it will get the job done) and I will have to do some wiring to fool the alarm system into thinking that the alt is still stock.

I am working on the turbo for this thing, it will sit nicely under the hood with no modifications, and should be much more streetable than the supercharger(which will find its way back on occasionally I am sure)

I am looking for a local vendor of weldable steel pipe elbows(shipping is killer from all the online vendors) but ran into some luck, it seems that OBX is making mild steel inlet flanges for the K26!

so all I need to do now is find out if the outlet flange is the same as any other turbo(K24, T3 etc...) so I can get a flange ordered up for that, which means that the only flange I need to make is the one for the head!

I took the exhaust manifold off the other day to pull the gasket(so I can make a pattern for the flange) and all the bolts came out! no penetrating oil, no breaker bar, and best of all, no broken bolts!

the threads have no corrosion on them at all!, I could not believe it!

gotta love a car that is this nice to you!

got a new set of seats the other day for $50
they are from an integra or something like that, and are way better than the crap seats that were in my car from the factory.

the years have not been good to my seats, the back was all bent and the foam worn out, the new ones are much better, with bolsters, adjustable lumbar support, all that.

almost a direct drop in too, just had to move the mounts on one side.


(old on the left, new on the right)
I only had time to mount one today, but it is so much better. I will get around to the passenger one soon.

i cruised around for about 2 weeks with 2 different seats in my rabbit.. i only had enough time to mount one, then the next time i had enough time, was about 2 weeks later.. lol.

just got my summer tires slapped on







they are 195-55-15 in the front and 215-60-16 in the rear.

the rear is aired up right now cause when aired out the rear rubs pretty bad.
I need to get some spacers and roll the fenders pretty bad.

the front is gonna go way down.

the rear tucks about 2 inches of tire aired down, so I want to lower the front to tuck about 1.5" of tire to match.

holy crap, that things way up in the air, almost as bad as my 86 GTI with 185/70s on it..

[truckinwagen]

like I said, it is aired all the way up, its gonna come about four inches down in a few weeks.

Super cool build man.  Sits as high as my Jetta with 205/40R17's!

updates!!!

got the nitrous and water/meth hooked up today,

nitrous bottle on left, water pump in middle, 2.5 gallon reservoir on right.


water/meth solenoids


nitrous solenoid


arming switches illuminated when on



WOT switch to fire the nitrous

the nitrous is triggered by the WOT switch and the water is triggered by EGT(on @ 1050* off at 1000*)
I had two nozzles hooked up to the water at first, but when triggered the motor bogged pretty bad after a bit(the water put out the flame front) so I cut it back to just one.

now the water spray does not seem to have much effect on EGT
the nozzles are 300CC/min so I may have to get some different sizes and mix and match to get what I want.

the nitrous does not seem to do much either, but I think the bottle is empty.
it does dispel some gas when triggered, but no visible spray... so I think I will go have it filled on monday before I make any final decisions.


I need to do some more tuning, but the hard work is done!

[R.O.R-2.0]

it should make a huge, white cloud.. just like when they purge the drag cars at the track. its probably empty. thats how my bottle reacted..

even on a n/a, when my bottle was full(ish) you could still feel it add some power to the stock engine..

[truckinwagen]

yeah, I figured as much...

anyway, pretty happy about how the install went, even if I dint have it working yet.
