Turbo Mike's Turbo 74 Super

Howdy yall. well i thought i would go ahead and start a page on my 74 super. Right now i'm pullin the motor out to do a few mods, and re-install the turbo set-up with some much needed mods to the intakes, and exhaust. I will pretty much be completely redoing both the intake and exhausts, so I'm pretty much starting from scratch.

Heres a pic of the old, badly designed turbo set-up:



This set up worked pretty good, but it could have definately been a lot better with a few mods. first off the eshaust header is an incredibly terrible design. all the runners are just welded together to a 2 inch piece of pipe in the center. a hole was cut into the side, and another piece of pipe (an inch long), was then welded onto it, and thats where the stinger would bolt up to. So thats going in the trash, and i'm going to use an actuall merged stinger header. then i'm going to raise the turbo above the alternator, so it will all fit under the decklid.

Also the intake T pipe, that goes from the turbo, and branched off to the stock endcastings, were made with pipe that was WAY too big in diameter. so the pipe went over the endcasting, and was clamped down on the end casting this caused gas to fill up the bottom of the tube. when i took the kit off, i had about 1/2 a cup of gas pour out of the intake .

anyhoo pics to come soon

today i didn't get as much as i wanted to to done, but i got most of te stuff off the top of the motor off. here are some pics:

What i started off with:


got both of the coils off (one for ignition, the other for a flame thrower ):


Ugly car isn't it. MAN i need to lower that damn thing, lol:


As it sits now. i was gonna yank the motor out first, but the car makes a great engine stand as is, lol :


Wierd marking i found on the engine just above the TDC sensor for the factory diagnostic plug thing, and next to the starter bolt:


hope to have the motor out tomorrow, and maybe even start on the intake, and trying to hunt down some good used/ cheap parts to get this thang goin. more to come...

Is this the car that you took off the turbo and it ran better?

I think you got it backwards, lol. I put the turbo on and it ran MUCH BETTER, lol. a hell of a lot faster then stock. infact it was about the same power as my 2085cc stroker motor . the turbo is a t03, so its a tad big, but runs amazingly well. i hope to get it ready for YUBUGGIN at the atlanta motor speed way. I'm curious as to what it will do in the 1/4 mile . i might go a little higher on the boost. i was running 8lbs before, and hope to hit closer to 10-12.

the only reason i took it off was because the float in the carb busted, and was dumping gas into the intake

if you are looking to run 1/4 mile at ams you will end up wrecking your car,its only a 1/8 mile drag strip

lol, oh. i've never actually drag raced there, or anywhere before. i'd love to see what my little 1600 turbo will do, lol. maybe next year, i'll see what a turbo 36 horse can do .

i know its been a while, but i've finally got the engine taken apart, and have started prepping the block. I've started with prepping the block for full flow. It was a real PITA to find the correct NPT taps, and plugs, but i finally found a two places who sell the stuff i needed

Here's the taps. one is 1/4'' NPT, the other is 3/8'' NPT:


i also got two 1/4'' NPT aluminum plugs:



First task was to pull the plug on the case for the return full flow fitting:


Here's the screw:


Heres the end of the slide hammer with the scred screwed into the plug:






I still haven't decided which fitting i want to use here, so i'll leave this hole alone for now.

Next i started on the oil pump gally hole:







after this i tapped my 32mm oil pump as well, and got the plug installed. This is where i stoped today. Seems like i've gotten nothing done, but its a pretty tedious task. every half a turn, i unscrewed the tap, and sprayed the shavings away with brake cleaner, then re-oilied it with some motor oil. that was definately a learning experience. It was hard to keep the tap perfectly straight in the holes. they kept going sideways. any ideas or tips on this? the good thing, it the magnesium is pretty forgiving, lol. if anyone sees anything wrong or have any comments, please educate me, as i'm sure i'll be doing something wrong soon (if not already)

why did you tap the case? never seen that done before,as long as the oil pump is blocked off no need to cap the case

is you is or is you aint done with this bish yet?

hahaha. i wish. been busy with everything else, lol.

oh, and i tapped both the pump and case, mainly due to paranoia on my part, lol. If the oil pump, or case wasn't a perfect fit, it will cause low oil pressure. it didn't take but a few minutes, so no harm done. better safe then sorry.

been a while since i've worked on ole yeller. I've decided to just do a complete resto. started on some body work before i yank the body off. So started some paint stripping. I use the paint striper snot they sell at homedepot, best stuff ever. just brush it on, and the paint litterally falls off:



While strippin the front apron, i discovered a bunch of bondo. Cant have that, so off it comes:


Drilled out the spot welds:








Here's a closeup of the bondo. bondo all along the bottom. was gonna try and pound it out, but its cracked in several places, so screw it, just gonna order another one:


Here's the old struts:


and the new struts and sway bar from topline:



offset casterfix sway bar bushings (7/8'' swaybar):


Rabbit/ scorrico inserts:



If you look at the pics closely, you'll notice that the struts i bought are for the older 71-72 super bolt on ball joint style suspension. i did this because i'm gonna use the older suspension on my 74. and the reason is because the late model like mine uses stamped steel control arms, which were FUBAR. so since i'll have to replace them anyway, i'll just go with the older style thick cast control arms, and the proper spindles and i'm good to go. plus i'll be able to flip the tie rods with the early style spindles (the topline kit came with the flip it bushings).
