7mgte vs. 1jzgte

i have an 89 toyota supra mk3 (turbo) and i am debating on the 1jz swap. i understand that the 1jz is twin turbo and has 280 hp stock as oppose to the 7mgte which has single turbo and 230 stock. i am just wondering if there is a better chance at me reaching the 400 hp mark with the 7mgte or the 1jz. i know its possible for both but which one would be cheaper? can you help me through the process of reaching that goal with each engine? can you recommend certain products for these upgrades?
thanks for your help.

7mgte would be easyer to accomplish due to aftermarket support, its really REALY hard to find parts for a 1jzgte becuase they were never sold in the us...y dont u just do a 2jz swap instead?

b/c 2 jz will kill his budget with just the engine alone...

and based on your post i think from your understanding twin turbo is better...

just to set the record straight ITS NOT... all high hp supra move to single...

for our cars(7mgte) you can reach 400hp preaty easy (with cash)

main key for 400 IMO is t61 turbo...

beside 1j cost so much that you might asweel keep your engine and rebuilt it for the same price... full rebuilt is WAY better than some jdm motor

he didnt say he was on a budget and it ould still be cheaper to hit 400 Hp on a 7m, i know that, im telln him not to do the 1jz swap and if he has the money then justdo the 2jz swap, it has more potential then the 7mgte, im not saying its a bad motor just the 2jz is better
but how do u figure i thoguht tt was better than single turbo? u dont know me so dont make a preconcived judgment, thats like me saying oh " i know u dont think a hemi is the best kind of motor"

dont try to put words in my mouth, you and all ur 15 posts watch out u know what ur talking about..

You really like that T61 for some reason, there are better, smaller, and cheaper turbochargers out there for a 400hp goal. Of coarse not all high HP Supras are single, if you have a very high HP goal, want alittle quicker spool, or any other number of reasons a twin setup is not out of the question. As for you 89suprasocal, search, this same 7m/1jz topic has been brought up too many times on this forum alone and countless times on supraforums.

ive seen some chill ass setup w 2 diffrent size turbos before...one to spool in the low end and peak and the other (bigger) turbo to keep spoolin till redline...

kinda plays in the fact w the 3tgte(i think) twincharged version, had a super and tubo charger, superchager went for the low end and a bigg ass turbo kept the high end goin

theirs a reason for me liking the t61.. first its a great turbo for 400 hp AND if you decide that you want more power you can go further...

and yes there are less expensive turbo out there... heck 60 trim or 60-1 trin will support 400hp... but the question is how long they will last at high boost and ruff driving...

it has been proben time and time again that a 60-1 trim is a better turbo BUT has like 10k of life expectancy b4 it blows....

franckly i do not bother with any other turbo as as with alittle more cash you can have a t61... wich is VERY MUCH prepared OVER smaller turbo by the mk3 community..


and about 91 Celica St comment... unfortunately i know what im talking about... and ive riden and drove mk3 that has 1j and 2j..

1j is cool but not much power def with the 7m...

the 2jz how ever is the power maker...id def. go with 2jz if you plan to go over 500hp...OR if you just have no budget and can affored such beast in an mk3...

dude wtf do u even read my posts? i said the 7m is better then the 1jz to have(no aftermarket support in the usa so just buying parts alone would be a pain in the ass plus be hella $$$), and that if you actually have the money then go for the 2jz, if not just mod ur 7m, damn you poeple need to learn how to read

You are half right. There is no aftermarket support for the 1JZ in the US. Japan and Australia are another story. The engine production run lasted through the 90s. The 1jz Soarer is rather popular down under so there is plenty of tech support and parts available, and the best part is that the websites are all in english. You can get parts from down under on ebay.com.au. Most folks will ship to the US if you ask nice. There are also plenty of tuning shops specialising in new and used JDM parts.

Then there is the fact that all these parts are the same. things like fuel injectors, piggyback computers, turbo chargers, etc. are all made by the same handful of companies world wide. For a turbo kit all you have to do is match it up, and have somone make you a manifold. There are plenty of shops all over the US that have been making headers for years. Just go in and have them make you one. It should only cost a few hundred dollars. Getting a rebuilt turbo is just as good as getting a new one at half the price. It is all out there, its not expensive, and all you have to do is make a little effort to search the web.

but at the cost of a 1jz swap, plus the extra cost of the aftermarket parts make it way more expensive to mod then the 7m

Exactly, I can vouch for the cost aspect of it. I usually pay as much for EMS shipping as I do for my rare parts. I've found shipping from Australia is just as much if not alittle bit more than EMS from Japan though. Good luck using a couple hundered dollar manifold, you do get what you pay for with most things and a turbo manifold is one of them. Take SSautoCrap/TurboXcuse for example, most people have no problems, some won't fit right, some welds crack and flanges come off, that's the price you pay. Unlike a high quality TRUST/HKS/BLITZ/SARD/ect manifold, I will gladly pay double the price to know I won't have any problems with that part for the life of the car. :tongue:

yea i made the mistake of buying a shitty header that wouldnt even bolt up, but i was luckey and got all my money back :) yay
