can i turbocharge my N/A 7mge?
 

can some one tell me if i can turbocharge my 7mge?
and what would i need to do make it work and survive?:dunno:

As for your question, I don't recommend it.

For me, too, a very topical issue. I would like to know someone turbocharged these engines?

well if you were to do it you'd have to swap the ECU, plus its a good idea to swap the injectors with a turbo models injectors, swap the manifold with a turbo one, put on the stock inter cooler setup off the turbo model, I'm not to knowledgeable on the supra's (more knowledgeable on DSM's) run all your oil and coolant lines. But like I said I don't know much about the supra's. I suggest looking around very thoroughly before attempting, I dont know if the bottom end and top end in the 7mge is relatively the same as the 7mgte. If it is possible then I suggest doing the conversion and running a low PSI because the transmission will more then likely be different between the two.

thats just my 2 cents but I'd follow what the more knowledgeable members are saying.

I've done a couple... I've also spoken about it, in depth, so many times on this forum that I now just feel irritated inside when I see new threads asking about it as you obviously didn't look very hard.

Synopsis of my posts: "Don't do it, it'll end up costing at twice as much in the end."

I have a N/A supra, and looked into turbocharging. The best bet is to do a swap with a turbo engine and engine management system. Slapping a turbo on the N/A engine will be expensive and not work well at all. Swapping is also expensive, but at least you'll have a system that was engineered to work well as a turbo set-up and can be very reliable.

You would be better off buying a Supra with Turbo. Like Auto to Manual you are asking for trouble.

I see new threads asking about it as you obviously didn't look very hard.

how about a 2jzge? and please if you have a link on the 7mge or 2jzge thread stick it up here bro!

Who is this reply directed at? I don't follow...

Any information on turbocharging the 2JZ-GE will be in the MKIV section.... You'll get most of the same answers though: Lower compression pistons, add oil cooling, swap electronics, etc.

u bet cre thanks!

The question of this nature, in the engines and the 7 mge 7mgte have a problem with oily starvation in the sixth and fifth cylinders?
I apologize for my english, I use a translator.

i dont understand are you asking if there is that problem or have you run into it already?

No, the 7M does not have any oil issues which are very common, at least not in the Supra. The people who have had these problems are typically people who "drift" and even then it is not a common problem. It can be addressed by adding more baffling to the pan and/or adding a "crank scraper". It is also safe to run up to 1 quart more oil than specified but keep in mind that this does add a bit more resistance that the crank has to overcome as it rotates.

Ok. Here i was thinking the supra has never had an oil issues, then i heard that and thought thats odd. Good to hear im not crazy.

Iv never drifted my supra but i do regurarly autocross it and have never had any issues whith oil pressure, burning, ext.. now i do run about 1/4 of a quart extra oil because mine burnes about that much between changes because of it being 135k miles and me just restoring it from sitting for 7 years, which doesent seem bad for its age( no blue smoke in tail pipe thank god)

Keep in mind that the stock oil pressure gauge is dampened and may not show a momentary loss of pressure... It only has to happen for a second. But no, it's not a common issue at all.

So it's just a matter of take it out, open it up and moding from there and close it back up properly. Any idea what would I need to modify if I have the sender unit open( when you say sender you mean the gauge face and the fat part that houses all the components that make it work I hope). For this little project I might end up buying another OE unit so if I screw up atlases I didn't do that to my cars unit. I hope my questions aren't getting annoying for some one that has probably more knowledge on it than I like yourself Cre

I'll move this discussion to a new thread.

Sender = Sensor... Not always, but close enough. It's the metal can or bell under the exhaust manifold... and it's not going to be straight forward. I can't remember what the internals are like anymore.



EDIT: Oil pressure gauge discussion has been moved here: http://www.toyota-supra.info/forums/...ification.html

Hence, the problem with oil starvation in the cylinders, there was a drifter?
To install the turbine on the engine, something must be done with the lubrication system, to improve it?

The only people I know of who've had trouble with this were people who did a lot of sideways driving while at high RPM. Most of them were drifting (or trying :P).

I do NOT recommend putting a turbo on a 7M-GE. Yes, the lubrication system must be upgraded and cooling must be added.

be safe
 

It is so much more than the oil pan, the 7MGE was not designed to handle turbo. Why should Toyota spend extra money making engines that will never need the extra? The following is my quick guess

computer
need the turbo with all connections
bearings
the compression is different, so the rings are wrong, add head and valves.
oh the exhaust, there is a size difference right?
You would have to overhaul the engine to bring up to specs. Is the engine blocks different? Then the transmission, differential are wrong.

Of course you can do the job on the cheap but my guess is the engine would not have a long life expectantly. Then there is the question, what will fail first? Then there is the question of your safety and those around your racing.

Look be safe and do not do STUPID things! If you want to drift do it in a car that can take the beating! You do not want your last words to be "hey guys, look at this!!"

This car is not for drift. If for drift, then I would swap the engine CHEVROLET CORVETTE LS2 6.0. I want to leave his native engine, but to increase capacity without changing it. I have to Supra, Architectural project was Kia Turbo Pro Cee'd, which also had to install a 2.0-liter. engine turbine. There I installed, head gasket was 3.0 mm and 8.4 degrees from 10.2, injectors 630cc, oil cooler, inter cooler, fuel pump wallbro, exhaust manifold for turbo, turbo ..... and it came with 143 hp at 1.3 bar boost to 300 hp

And on this I'm interested in people who have been through it. On, kia, improvements to the lubrication system, was not, run the turbine at about 80,000 km of modes, the gas in the ground.

Still I have the feeling you want to do something extreme. Turbo would not do a lot for me, get a police "escort" more often than not. Think the sound attracts them.

Still wonder if you understand my message? If you put tougher a substandard engine you will receive substandard results. Still think you are better off with a turbo model. You can then concentrate on what you want to do with the car and not pour a lot of money on the conversion.

To say it simply, it is MUCH better to buy a Supra with a 7M-GTE. Much on the GE will need replacing.



I'm now done beating this dead horse.


Ranma, not everyone who wants a powerful build drives like a crazy person.

Didn't say they do, however he may bring him onto a race track and if you are pushing your ride, it should be the best possible. I would like to try my guy on a nascar track for grins giggles laugh and excitement. My guy will top out but he is safe. I have no doubts on the mechanical.

My pet peeve is people trying to get by on sub standard. In the end it always cost them more.

And what do you think about this project?

I've built similar and they're seldom reliable. I've built them and watched them burn holes through pistons, overheat and crack blocks, burn rings and lose turbos due to coking oil because they didn't address the oil cooling concerns. I could list, very quickly, all the potential failure points of that build but this is all a waste of time at this point. I have seen many of these attempts fail horribly and the owners usually end up either abandoning the MKIII altogether or finally listen to the people who told them not to do it from the beginning and go with a REAL GTE swap.

I have nothing more to say this is a waste of my time and I'm sick of repeating myself.
