MA70 question...

These are all of the readily available coilovers for the mk3 supra. There are a number of very limited production kits from other companies you may be able to track down second-hand from japan, but by the time you rebuilt them you'd probably come out ahead to buy a new kit.


As for the LSD question -- all turbo mk3's have it, and the NA mk3's with the sport package have it. It is a fairly stout 1.5-way clutch type, but you will still want to change the fluid regularly. Also, adding that special "lsd additive" will make the lsd less aggressive, so don't automatically buy it because you think it'll make the lsd rock -- that stuff is designed to prevent the lsd from chattering when you're going 1mph in a parking lot with the steering wheel fully cranked.




And as for turbo vs na: A stock NA has enough power for drifting, but personally I couldn't see maintaining higher speed slides with it. And it is a hard engine to get more power out of. However the non-turbo engine has a very linear power delivery -- it makes 80% of its peak torque from like 1800rpm through 6000rpm. This means it is much easier to modulate the throttle.

A stock turbo car is probably worse for drifting than a non-turbo, but if you add full exhaust you'll get more power and better spool time. Unfortunately modulating the throttle with a turbo is more difficult and it will take a lot of practice to adjust your throttle without coming out of boost (and then having to wait for it to spool again). The stock turbo (ct-26) is quite large for it's day as a stock turbo -- only the Buick Grand National came with a larger turbo from the factory -- so it doesn't spool as nicely as other factory turbo'd cars...

I'd personally take a stock 7M-GTE and swap the engine from a JZX100 (Mark II) or a JZZ30 (Soarer GT Twin Turbo) and match it to a nice Getrag V161 from a JZA80 (Supra Mk. IV). 1JZ has tons of power potential, twin turbos which which make the lag smaller when compared to a stock 7M car, and the "JZ" in the name, which means hat it has a practically bulletproof block. I don't think that swappping a 2JZ in would be a good idea. As far as I remember, the weakpoint of a 2JZ were the connecting rods, as they were quite long when compared to those from a 1JZ (2JZ is basically a stroked 1JZ), what made them more, let's say, "flexible". And you won't need to change all the electronic stuff lice the harness etc. to make it works. In a 1JZ you will just have to swap the stuff from the other car and drive it.

The MA70 curbed stock at about 3400. Racing seats, back-seat removal, and spare-tire removal will put you at 3200 lbs. It's possible to get it slightly under 3000lbs (basically FD weight), but you're going to have to strip the whole car =P

Which MA70 is that? the Hardtop N/A 86 you mean? Most 89+ targa cars (most are targa from what I hear) are 3450 or something. All us Turbo guys are like 3600lbs STOCK, with fuel its like 3700. Best car is those 86-88 N/A hardtops that are SUPPOSED to be around 3350 but those are the stripped ones with no LSD ect, A/C ect.

I'd think in the begging you'd want a N/A car but you really do need the power of the turbo for faster stuff. I found at 12psi on the Ct you need 80% throttle too overpower a half decent pair of 225's when sliding at say 35mph.

I've slid in smaller cars (Mk2 Supra @ 3050lbs 190hp6M) and you can really notice that turn transitions are made much easier with a lighter car BUT having lots of hp means easier slide induction and its fairly stable with its big weight (GTE car)once you get going.

In a 1JZ you will just have to swap the stuff from the other car and drive it.

Its not for the faint of heart a 1JZ swap, lots of harnass work, IC work, wiring ect, not as easy as some say, at least its well documented eh?

BTW my final word on older 7MGTE MA70's are that they are a super pig for maintanince. Anything that can will go wrong. And if you are even a quart low on oil you can starve the pickup and damage your bearings (leaking turbo+ down a quart + drifto @ 5000rpm = spun rod bearing) Older GTE cars can leak oil from a dozen places, all can get you down on oil, and then BLAM! rod knock.

I'd get a N/A if I could do it over again, so much less hassle and not 20mpg on Premium!@#@#

heres mine on tein super streets

i get good deals on tein suspension, let me know!

[300zxttfreak]

Real nice, that is what Im getting is Tein SS dampers

but I was wondering, where could I find 1jz engines for sale at? and also how hard is it and what do i need to look out for?

and what do you all think would look better TRD Sports T3 or Volk SE37k?
thanks in advanced

The Bomex A1 kit. I love that kit.

Turbo is probably not the best choice if you wanna bring that thing to the canyons, but that's all you. You're mods are pretty right on, but luv2 is right. You need to concentrate on suspension. An anti-sway bar will help you initially, and look into some coilovers for the long run. (I'm looking at JIC).

Also, weight reduction is your friend. For something like $200 you can get Sparco Speed seats, which is about a 100 pound drop. Good luck, and welcome to the MA70 drifting life -_^

I disagree as far as for canyon driving. My turbo MA70 was a blast, and very fun to drift! the weight sucks...3700 with me and a full tank of gas, but it still will handle....swaybars!!!swaybars!!!!swaybar!!!!


here is a pic

hey kineticdb8r! could you take a pic of your front lip, how you did it and what kind did you use as could see i need it too!

OEM lip is expensive or if somebody has one, i'll buy it

MA70's

I drive a Ma60 myself but my buddy has a MA70 we are working on. The CT26 turbo can net a little more power with a different elbow pipe. www.rabidchimp.com makes one. Its in the MkII turbo section but it is a MKIII part. Also thier improved intercooler can help net a few more HP. All the M series blocks had a head gasket issue. They are very intolerant to overheating. I have found better cooling and a metal head gasket rounds out the bullet proof M series blocks. Also some TRD test drivers have said Increasing the head bolt torque using new bolts also is a cure. Id advise junking the factory TEMS. Remove ALL of the air conditioner garbage if you want to reduce weight. Remember to have a repair shop discharge the AC for safety and legal reasons. Get the best coil over system you can buy, newer sway bars and a full suspension bushing kit never hurts either.

just my $.02

factory specs for head bolt torque are wrong for sure......I went 30lbs over I think......never had an issue after my HG issue....ditched AC..etc

good metal HG adn a super cooling system and you are gold

I used some plastic sheet for my lip..alas I no longer have the car to take a pic...I'll see what I can dig up as far as old pics


the plastice sheet came from a dirt track/oval track supply place...just some flexible plastic really.... pop riviet on and you are good to go.

I went long and trimmed when I found out where it was scaping on the ground

[ma71supraturbo]

the mk2 is actually "bigger" than the mk3 (in terms of length). It is lighter, and certainly doesn't feel as big (until you turn that steering wheel 500 times over to countersteer )


As for weight, my '87 hardtop turbo started out at 3620lbs (with an automatic). I've since gutted it, put on a home-made fiberglass hood, and swapped to a manual. Last I checked it was at 3050lbs, but I've since added coilovers (lighter) and installed some additional bracing (heavier)

but i do have an extra set of eibach prokits at our shop that i am selling probably w/ the front KYB GR2 struts. let me know guys if you guys want it 626 815 0355 . i just used it for half a year then went with the tein SS .

[NISMOZERO]

hey guys i was browsing some pics, do you guys know what kind of wing or who made it? and what do you guys think. me thinks i like.

[ma71supraturbo]

I believe that is the regulus wing, the front bumper is either regulus, or the MAXX knock-off "Evo" bumper
