This post was also placed on Supramania.com... basically i dont feel like re-writing it so here it is again...

 

Good chice of a car. its my fav of all time.

the back seats are pointless to take out they dont weigh shit. like 5lbs the only foam with that support wire. it looks better just to leave them, fold them down if you want the 2seat look.
the drivers and passenger seats are where you will find a lot of that bulk. they weigh in at around 100lbs togather. some light weigh race seats are a must if you want to save weight
next there is a super heathy layer of tar mat on the bottom of the car take a weekend and get all that up, make sure you paint the metal after is off so it doent rust out on you. lay the carpet back down and you will never miss the tar.
the hood is heavy, theres a carbon fiber one someone makes, its like 10lbs vs 50 or somthing.
the wire harness, haha you want to go dfi toss that wire harness in the trash. or give it to me. i could use one.
im sure after all thats done youll find a few more weighted areas, and i'll think of some more..
my car weighed in at 3380 with gas in it and me in it as well on certified scales.


of two supras ive owned, ive never broke a tras, the first supra was an Auto and it had a level 10 kit in it. upgrade clutch packs and modded valveing for "firmer shiftng" or they say, i called it beast shifting. this trans coulda have taken 600hp im sure.
the second supra was a stock manual. i have never looked into upgrades in the trans and ive never seen an os giken or other brand gear set for it, this doent mean it doent exist. they do make a clutch for it tho.
the MKiv trans does not bolt on. sorry, that would have been nice if it did. its pointless to rebuild them. you can get them for about $150-$200
i took care of my cars and thats why the trans never broke. others have not had my luck, ive seen supras go though many transmissions.
i do not think the supra trans is as strong as your Z's trans. if you do find out about a easy trans swap let me know ide be intrested in the info, also you could do what the corolla guys do. the take a celica trans thats much beefer and weld the stock bell housing to the celica trans. you could do somthing like that with the mkiv getreg. some trans tunnel mods would be needed as well, but it sounds like you wouldent mind that for a trans thats known good to 1000hp.

All Turbo supras came with LSD. and all Non turbos that had the sport package (LSD, Tems, rear disk breaks, ABS)
oh ya back to weight savings, loose the ABS it sucks.

Again like the tansmissions a lot of people have broken them. but ive never broken one eather. i guess it just really comes down to how you take care of it.
I suggest redline in the trans and diff.
on a side note. if you are into drag racing get the Non turbo Automatic Diff, its a 4.11 the highest ratio offered. and it came in LSD.

its not too long, good questions. spelling haha i cant spell if i needed to save my life.
oh ya welcome to toyota world sorry to hear yer Z got messed up that thing looked like a beast.

 

well i am still deciding... the choices are finishing the Z.... going MK3 and moving shit over from the Z (sds, fuel stuffs, guages so on) .... or going S13 with an SR in it..... the goal is to employ modern engine management, with modern turbines (read GT series ballistic turbos) to come up with a great flexible powerband..

 

and you saying Z31 is the fav car for you of all time is just the same as me.. I cant find another car that LOOKS like it does, rides like it does, feels as powerful as it does...... I know i wont ever be as fast as enthalpy, or turn as sharp as jesse in his mr2. but i dunno, the Z has some kinda aura with it, it feels powerful

 

No no mk3 is my fav of all time. the Z31 follows closly in there some where tho.

dont go S13/SR thats too played out now.

 

Somthing i didnt think about on the mk3 idea.

get a mk3 with a blown HG. $300-$1000

order a 1jz from one of the importers. $1500

get the getreg 6speed it will bolt on to the engine, but need work to get it into the car, $1500

at this point you will have a very powerful and reliable with the SDS and turbo your talking about.

youll have about $2000 worth of parts to sell too when its all done.

 

is the 1jz distributer fed?

 

no its coil packs, one on each spark plug.

 

Kirk, you missed the part where he said he had the turbo and fuel system, so the Lex/550 does not apply to him, the power to boost ratio you provided does not apply to him as well sence he has a T78. with that kinda flow rate. the 1jz should be in the 375-400hp area at 12psi cant really compare a stock 1jz to a modded 7m, albit lightly, and call it the word of got for a guy who already has a SDS, a bad ass turbo, and all the other nessasary parts to make it all work, to put into what ever car he decids to get.

this supra at step 1 if he gets it will be 10 steps ahead of the supra setup you are describing.
