what body style comaro do we source the socks from?
its '82 and up.
I tried a set of stock replacement sach's first to see how well they really worked before I spent any real $. Once I tried them, I got a set of Comp. Engineering 3 way adjustable drag shocks for the turbo MKI which work great.

hey man

hey man just seen that your teaching a lot of the things that I taught you when I built my 80 the first time. you said a mki is not much litter then a MKII I thinck 400+ is a big difrence and it is very easy to get another 250+ lbs out of the MKI and still look all stock at first appreince.

Im also glad to see all the new info for the MKI s Im sure you had a lot to do with that. it is going to make my V8 swap a lot easer.


There are many ways to go about anything but as far as I'm concerned, doing the 5M/6M-GE swap into the MKI can be quite easy using many '82 5M-GE parts. '82 Supras have so much in common w/ MKI's its unreal. The airvalve set up is identical so I suggest just using the entire '82 upper plenum. You can just port it out to match to the PP lower runners. And for simplicity, I just used the '82 vac advance distributor. When I did the swap in my '80 - I used an '84 P-type motor, but just w/ '82 parts to get it all to work w/ the least amount of fuss. I really didnt expect it to turn out all that great - the MKI isnt that much lighter than the MKII plus loosing some power using the earlier parts (compared to all the '84+ PP parts), but it was really impressive.

Ken - that list kicks ass; great contribution! I've seen this or that part listed over the years so I knew they existed, but its awesome to have a list of part #s w/ prices; good stuff, hopefully someone will sticky this. Considering how well my black PP MKI handles - when you get around to installing all those parts, it should be quite impressive. Still going to need to address the wheel hop issues and stiffen up the car to get the most out of everything. The one thing I cant stand about the pre-'82 celicas and supras is that terrible steering box. Even if you have a tight one or adjust out the slop, the ratio sucks. I believe the key to top rate handling would be converting to rack & pinion... I'm probably going to do this when I build up my next turbo MKI.

Cool Ideas! How hard was the coil upgrade? I am lookin into doing some suspension work here soon and need to get some springs and stuff. Good job!

Awesome info. I will study this and start ordering parts. I am currently running KYB Gas Adjust shocks in the rear and their struts up front. Maybe new springs, bushings and sway bars would really help out. The engine upgrades adding 30 hp plus is great! The wheel hop is terrible on the MK1's! I remember my teenage tire spins causing horrible bouncing. Also the worn rear bushings caused me 3 bent driveshafts too. Keep the info coming guys and I will read religiously.

possibly he meant that it broke the u-joints as bad bushings would not cause the shaft to 'bend'. The original bushings are way too soft when new - and then after time and use, they become terrible, making the wheel hop and slop even worse. The wheel hop is terribly stressful on the rear, trans and driveshaft but likely the rear iteslf or u-joint will break first, which happened to mine several times over...

The original bushings were getting soft. When I would slam the car into second gear and get rubber the driveline would torque up and hit the floor. It was in a bind and bent it in the middle. I cornered the market in drivelines at the local junk yard for a while until I just stopped killing second gear.

Wow, this is the gem I have been searching for but could never find. Tons of great info on the Ma4x OMG im so excited to start working on my PP Ma47 again! I should have it running stock with a w-58 soon.

Im still a n00b when it comes to alot of stuff...I have a w-58 trans, should I get the 5m-ge clutch or does it really matter?

I discussed this on the first page/ original write up but real quick - they are different - if you run the larger '82+ W series clutch, you'll need the matching flywheel as well. The only real benifit of the MKI clutch set up is that its lighter but it wont take as much power or abuse. It really depends what you're doing w/ the car...

Right now I just want the car to run. All it needs as far as I know is a starter, valve cover gasket, trans and clutch. I could have it running in a weekend. So stock, I could just run the 5m-e set up. Thanks Damon.

FWIW - I was looking through my MkI parts catalog and came across the following sway bar info:

Rear Bar:
MA46B OD=15
MA47B OD=14
MA47B OD=17 (Performance Package)

It looks to me like there is a difference in the standard rear bar between the '79/'80 cars and '81. I wonder if they slightly reduced the bar to make the handling difference between the standard and the PP more pronounced?

The standard front bar is listed as the same for all three years (MA4# OD=22 and MA47B OD=24 Performance Package).
