What do I do???

[Scalpul]

Alright, Ive got a 1990 na. I love the car, I love the power, but its just not enough. Ive looked at many options, but Ive been going crazy trying to decide whats the best route.

1)Keep the 7mge and do basic mods
2)turbocharge the 7mge (n/a-t)
3)supercharge the 7mge (7mgze)
4)engine swap 7mgte
5)engine swap 1jzgte
6)engine swap 2jzgte
7) engine swap 1uzfe

Im looking basically for the most amount of gains for the least amount of money and stress. Any advice would be greatly appreciated.

 

[NDBoost]

well, 2JZ would be alot of gains but not necessarily the least amount of money. Go 1.5JZ or stay w/ the 7M

 

[92turbo4life]

wait supercharge a 7mge.. you can do that .. is it good?

 

[oscolivar1]

i dont know any one who has supercharged the 7m....
but im sure u can..... u just need a lot of money for fabrications....
im sure someone has done it....

i'd stay with the 7m block IMO

based on this comment i would limit my options to numbers 1 and 2 or 4.

One you havent listed is doing basic bolton and shot of nitrous, i dont believe it would get any cheaper than that.Assuming your engine is in proper running condition with not many miles

 

[GrimJack]

Number four FTW. It's been done many times, so it's well documented, you still have easy access to replacement parts from your local Toyota dealer, and it's the most painless method of adding a lot more reliable, cheap power to your car. Nitrous is another option, but remember that you need to pay to play with it, a turbo gives you the same power without needing to pay to refill bottles.

I concur, but if you are going to attempt to turbo your GE you should make sure that it is up to the task. First off how many miles does your motor have? Have you done a compression test? In all actuallity it will cost you almost as much to turbo your GE as it would for you to swap it out for a GTE if you do all the labor yourself and do it the right way. I just went the extra mile and bought another GE to boost, but Ill probably be a little under 15-1600 total once all is said and done.

 

[supramacist]

I'd swap...., real men that know how to drive don't use nos. That oughta put sand in someones clit. ha ha lol.

Swap a 7mgte.

End thread.

Not to be a knob but maybe the Mk3 is the wrong starting point as you WILL have plenty of both going into the project.

 

[supraman420]

Turbo your N/A, I have almost all the parts. But time and stress will be involved of course.

 

[Supracentral]

1)Keep the 7mge and do basic mods

Most expensive dollar per horsepower route to go - limited potential.

2)turbocharge the 7mge (n/a-t)

Not a bad route, can be a headache to get running right.

3)supercharge the 7mge (7mgze)

No off the shelf kits, uncharted territory, supercharging much less efficient than turbocharging.

4)engine swap 7mgte

Best route IMHO - direct bolt in, easy clean, fairly inexpensive.

5)engine swap 1jzgte

Doable, but again can be a pain in the ass. Tends to be far more expensive than 7MGTE swap.

6)engine swap 2jzgte

IMHO, if you are going to go 1JZ, you might as well dive in and do the 2JZ. Again, can be a big pain in the ass, and quite expensive.

7) engine swap 1uzfe

I wouldn't even go down this road. Way off the map when it comes to being "low stress".

My opinion is do a 7MGTE swap - it will give you the most bang for the buck, and it's a good platform to build on.

I disagree. The MA70 is a damned fine chassis to build on, and the 7M is a kick ass motor. Modding a car in general isn't low stress, so maybe that's the question to ask.

However I still stand by my statement that 99 times out of 100, the weak link in the MKIII is the owner. Do it right or don't do it at all, that's what it boils down to. Take shortcuts, and you are going to pay for it in grief.

That's signature worthy!

 

[IJ.]

Mike: He wants the lowest cost option and with a Mk3 for me this rings alarm bells as we all know how our cars reward cut corners! (the stress will follow)

 

[Scalpul]

Alright, lots to reply to.

I dont know that I really like to 1jz, due to the fact that there's limited aftermarket applications.
I really dont have much interest in nos. that would be the very last thing i would do.
Yes, people have supercharged the 7m. google 7mgze. youll find a couple sites but not much info.
I havent found any kits for turbocharging or supercharging the 7mge. All has been custom applications, and most were very pricy. the only advantages would be the fact that i could leave my same engine in there and that with either of these routes, i would push more hp than a stock 7mgte.
My engine has roughly 40k miles, havent done any compression tests.
One thing i forgot to mention earlier was that after whatever route i choose, i plan on doing more mods afterwards. the more options after the swap(or whatever route i choose) the better. I havent been able to find very many mods for the 7mge, other than a k&n fipk and a cat-back exhaust. A few tricks like messing with the afm and putting a resistor in to tell my engine its running cold. I havent really noticed much gains.
ive thought about getting a different car for the project, but i love my car and there are lots of options. I doubt i could ever enjoy something other than a supra, and as far as different generations, I like my mk3 the most.
The 7mgte swap is really appealing to me because it is cheap and practically slides right in, but thats somewhere around 2500 for only a 30hp gain. Im not sure that thats worth it. If im going through the trouble of a swap, shouldnt I go big? Ive only ever heard of 7m's pushing 700-800hp max, and thats with lots of work.

You won't find Supercharger kits. It's not a practical path to go down for a car that already has a turbocharged version. To dump all the money and R&D into heading down this role would be foolish. The reason you don't find turbo kits is they are not needed. You can buy other peoples old stock parts to make an NA->T car. However it's still not worth it IMHO.

If you have future modding in mind, do the 7MGTE swap.

These are dangerous and stupid modifications in my opinion. As I've said 101 times, do it right, or don't do it at all. Cheapo mods like this are a precursur to a BHG or blown motor.

First and foremost, it's not "only a 30 hp gain" only - i.e. - peak horsepower does only increase by 30, but the "area under the curve" increase is pretty substantail. The torque increase is also impressive. You can't really compare the accelleration of a turbo car to an N/A. Also, with some very inexpensive modifications, you can easily jump that peak HP & Torque increase up to 100+.

I'd suggest that you do a lot more reading before you decide to do anything. You are working from a few incorrect misconceptions, and you need to learn a bit more before you can make a truly educated decision.

Wow, Im glad you think Im an idiot. Ive spent probably hundreds of hours reading up on this and Im not planning on doing anything on a whim. As far as becoming more educated on the matter, why do you think Ive joined this forum(among others)? Thanks for the support.

i say gte swap, but as for money n stress, no pain no gain bro. Power costs money regardless, you get what you pay for, and if it were that easy and cheap every 17 year old would have a 500hp mk3 and we'd get bored of them.

Look, I understand that anything I do is going to take time and money. What I dont want to do is spend a shit load of money and later find out that I could have done something else that would have saved me time, money, and stress, and produce higher gains. Im not worried about cost. Its efficiency. Bang for buck.

 

[xarewhyayen]

well, I'd say 1.5jz then. Do your research here theres some good material. If i had the money, id go with that combo. Im having trouble keeping up with my 189,000 mile gte though haha. School is to blame for that though so its okay.
