high compression pistons, cams and oversize valves should do it. its not diffrent then a 5.0 other then its got 2 less cylinders and liters of displacement. An engine's an engine, configuration has nothing to do with capabilities of it. Think about it this way, 300horsepower out of a 7mge would be 100hp/liter, that would mean try making 500 horsepower from a 5.0.

It could defiantly be done, but the money you would spend on rebuilding the motor you would be better off spending the same money on turbo parts, spending extra on turbo and have as much power as the situation warrants.

You build a 350hp N/A motor thats all it'll have unless you rebuild it with something different, turbo motors are variable, build them strong once then moderate power with boost/turbo.

would be cool but not worth it as many said.

Being NA doesn't turn your motor into the mechanical version of the Karate Kid; special underdog magic abilities aren't granted by taking the difficult path to power. :biglaugh:

The only area a 350whp NA will trounce a 350whp turbo is SOUND. A NA 7M of that magnitude roaring and burbling along would surely turn a turbo invisible.
If that race were to happen in real life, I'm sure there'd be at least a couple bystanders swearing the NA was faster ("It sure sounded hella fast!")

unless the na had an open header, it wouldn't be louder than my car at wot. with a 50mm wg venting to the atmosphere, it gets LOUD! and i personally think my car sounds orgasmic, in fact, all this talk gets me in the mood to watch the videos i have of my car....... so if you'll excuse me, i have a car to listen to

These type of threads are almost silly (no offense), so I'll just help it keep going.

350+ rwhp in an NA? And reliable daily driver? Sure. A stroker kit should be considered- for a SMALL BLOCK CHEVY! A 388" sbc motor could easily make that kind of power without being anywhere close to the ragged-edge hand grenade of a motor that a 7mge would be. And probably cost a lot less even considering the swap. Blasphemy to all things Supra? Whatever. It'll work.

But if you read up on turbochargers in general you will quickly see that almost all motors should have at least one turbo on them. It is simply the most efficient power-adder for an internal combustion engine. And as long as it's not a rotary that's going to spit apex seals through the turbo it should last quite nicely.

But if you really want to be different and you make like $10k a week and have E85 pumps all around where you live, then push that 7m to the sky!
Individual throttle bodies - sounds even more wicked.






Put a V8 in it!

E85 on a GTE would still make more power...

bang for the buck, the Turbo will beat the N/A's ass anyday of the weak...

I'll never understand why people are "scared" of turbos. It's got a SINGLE moving part and if it fails, 9/10 times it won't do any damage. That other 1/10 it throws metal into the IC piping or exhaust piping, NOT the engine.

It's cheap and powerful, and the only time I've ever seen a horrible turbo failure take out an engine was on a non intercooled setup and one of the fins from the compressor got stuck in a valve...

Won't happen on a intercooled setup.

The N/A is the equivelent of the V6 mustangs and F-bodies. When modified, they only put out about the same power the V8 would have done for a fraction of the price.

If you want to be special and go all motor (or want to be in certain classes of racing where turbos aren't allowed), be my guest. Just don't be pissed when a BPU Turbo walks you...

Thanks for all of the great advice and opinions.

I will begin to go down the road towards an NA > Turbo swap in the future.

Where does the hive mind come down on the 7mgte vs 1jz vs 2jz and single vs dbl turbo questions?

Redacted per Title 18 USC Section 798
A gadget (which iirc was invented in Oz) that can run the engine without petrol using Orgone energy. Life force stuff. Serious ooga-booga if I ever saw some. Goggle it ;)

I do know people who run H2 or HHO (Brown's Gas) generators in their cars to boost fuel economy though. I'm told it works well if done right. Something like 10 mpg more on the highway. In theory one could even plumb the HHO from the battery into the intake but the gains would be minimal. The argument is at today's pump prizes every bit helps. Course, you don't have that problem ;)

I understand what you said and why you said it...BUT, suggesting a search indicates that said search would reveal an answer. Suggesting a search on an issue that is " can of worms" suggests there is no answer...just opinions.

I have searched enough to realize a few things...anything 7m is seen as a difficult engine to wrench on and is stuffed full of 20 yo tech...opinion is split as to which generation 'z' motor is the most difficult to install in a MKIII...some issues have been circumvented w/ a 1.5jz.

I am going to upgrade my 88 Supra (hence the thread)
I have adequate space, budget and mechanical aptitude (no actual experience)
I found the site as a source of all things Supra...
I would like to have 350+ rwhp
I would like my car to be a DD

bone stock 2JZGTE could fill that goal, but the wiring, ect is the hellish part...

a 7M could do it quite easily as well as the 1JZ... Personally, my opinion is if I already had a 7M sitting there, I'm gonna use it since it's cheaper than buying an unknown condition engine...
