Turboing the 5M-GE

[Malloy]

There is nothing wrong with being a racoon

[jdk_ii]

It is slightly easier for conversions now than it was
2 years ago.

Several have done the 5/6MGTE conversion
and worked out the bugs. They also determined
the limitations of this low cost setup.

They perform very well.

Around or before Steve's 5MGTE conversion, the
JDM 7MGTE's were an easy $1500. US boneyard
premium 7MGTE's were close to $2K. Then there
was the issue of wiring.

5MGTE was a much less expensive route.

JDM 7MGTE's are now well under $1K price mark.

To spend money on rebuilding a 5/6M for a turbo setup
is unwise, unless you are going full out performance
and have the funds and knowledge to do so. Or you
got some performance parts for peanuts.

Say you want 400 hp. Much easier and less expensive
to get to this goal from a 7MGTE than a 5/6M.

500hp+ Club? Well, the money 'invested' increases rapidly
when you get into this territory. You'll probably spend the same
regardless of which motor.

I agree, Jim.

But for the $ you can get good power out of a 5M-GTE.

If you really want 400 hp in a MA60 MkII Supra you're going to need some suspension and brake upgrades immediately IMO.

...in other words there are hidden costs associated with that kind of a power that are more optional at lower power levels (i.e. 5M-GTE vs. 7M-GTE).

In fact, anyone that considers doing any turbo project
should start with suspension and brakes FIRST

Otherwise, one is going about it backwards and doesn't
value their life or others.

As for the 5/6MGTE, it really depends on what one pays
for the 7MGTE components and the condition of the 5/6M motor.

My point is that one has to look at their objectives (short and long term) and what their real cash outlay will be.

The 5/6MGTE route is a good deal, perfect power as long
as one shops wisely.

In this discussion theres a huge gulf between people who can do the labor themselves and work out the kinks themselves-- and those (like myself) who can install things like headers, but dont have experience with engine transplants. I feel confident I could turbo my 5M on my own especially if its in the form of a kit, but I'm not equipped to swap a motor. Now on another thread theres a guy that bought a 6M and was planning on installing it himself this weekend. So he posts, 'is there anything I need to know before I start?' ..SilverMkII's answer was something like a wake up call. So for me its not even about just which motor is best for the short or long term. Its also about what can I or cant I do myself. A big part of the reality is doing it yourself!

Last but not least: power to weight ratio is the bottom line. Dean Anderson ran all the numbers and in an extremely light MkII you dont need enormous horsepower. A wet stock MkII with a driver is at about 20lbs per 1 horsepower. A 'fast' car in general is at about half of that ratio or 10lbs per horse. A lightweight MkII only needs the power of a tweaked 5M turbo conversion to be in the ballpark of 10lbs per Hp, but a stock car needs that much more. It needs a 7MGTE to reach the same ratio (in general.)

p.s. Reg Riemers(sp?) maxxed out 7MGTE Supra is at around 6lbs per horsepower! Thats supercar performance in a MkII. Its also the creation of a guy with tons of knowledge and experience behind him (and bucks), doing the work himself. Like I say, there a huge difference between those that do and those that pay to have done.

[cliff201]

sort of expanding on mrael's discussion. For those of us who might have the ability/knowledge to do minor modifications but don't have the knowledge/ability (or at least the confidence) to install a turbo on the 5m, is there any professional mechanics that have experience doing this sort of thing. If one were to find the parts themselves and have a knowledgable person install the turbo would it be cost effective to have a shop do the work? Eventually I am hoping to be knowledgable enough to do this type of thing but in the meantime am I doomed to always knowing but never experiencing the potential of this car?

Time to turbocharge the 5M-GE!

As I do my homework for this project, I'm looking for sites that describe the
process of turbocharging the Mk2, using either a 5M-GTE, 6M-GTE or 7M-GTE
setup. I've compiled the following list of links.
If anyone has any others that I've missed, please let me know. I want to be
sure to do all my homework and learn from other's experience before doing all
the work on my Supra.

Ok, now I want to tread lightly with this:
I thought I was doing myself a favor by making my own intake pipe but I was wrong. I should have gotten one from Aaron at rabidchimp right from the start. I finally did do that and it is on the way to me as we speak. Now for the controversy: Aaron is going to market a turbo conversion kit for the 5M and I really, really, really want to support him with it. I have been exchanging a few emails with him and it still might happen that *I* am the first person to buy one of his full kits. The drawback is that his kit uses mainly new OEM parts, and this drives the price right through the roof!
I havent heard back from Aaron yet about my suggestion that he sell me (and everyone who is interested) a complete kit that uses salvage parts as they are available, and I have no idea how he will react to that suggestion. He can source them himself and them add a markup after he inspects them-- that would be fine. He can let people know if he cannot find certain things.. theres a limit to wreckind yard part availability and we all know that.

I agree with all of your 5M pro-turbo ideas but not having a garage I am limited in what I can do in the driveway. Having a kit is great, and I want to support Aaron, but right now its just not happening. Hell, I'd pay ANY OF YOU wrenchers $1500 to turbo my 5M tomorrow! (includes all parts)
But talk about two or three times that much and it stops making as much sense.

So I'll see what Aaron has to say. You know, I could be happy with a turbo 5M nooooooo problemmmm. But my first choice is to help Aaron, buy a complete kit, and be happy that way-- not scrounging around for parts all over the place like a starving racoon.

Ok I'll do it! (Ship it to Canada) <jk> but hey!! want some center caps for your car?? I have 17" customs now and a few parts cars, I could set something up for you.

A link for a Rising Rate fuel pressure regulator for only 140$, the cheapest i have found yet. I want to post it here for when the thread in general dies.

rabidchimp turbo kit is out. http://www.rabidchimp.com/mk2turbokit.htm but is 3500...

[supraII]

That is why my is still sitting the garage lol. Dam it
thanks!

[SupraBob84]

Something that I think needs to be said here that hasn't yet... The RRFPR is only good for supporting about 7PSI. After that, you need something else (like the APEX-I S-AFC I just ordered )

Also, when i do my 5M-GTE (shooting for April time frame right now), I'm gonna be taking a load of pics and posting them with a build write-up. I'll let ya all know when its up and done...

[lbto]

interesting... only 7psi out of rrfpr? hmm... so 7mge injectors and s-afc will support more then that?

Okay, so what were the compressions in different versions of the 5M-GE's? I'm starting to think an earlier 5M-GE (82-83) would be better to get than a newer (85-86) engine, because if I want to turbo it, the earlier one will start out with a slightly lower compression already.

Any thoughts?

Jeff, you should be ok with the higher compression motors. Infact, get your hands on a 6mge (9.2-1) for some real performance. With it's larger displacement, and higher static torque, the 6mgte (CT26) would be the ultimate street setup for light to light action.

You can pickup a good 6mge from a local importer for about $580 to $600.

Hello everyone,this is a great forum for us newbie's with a supra,such as myself.My ? is this,I just rebuilt my 5m-ge which took me about 2months.I've replased every hose under the hood,every gastket under the hood had my injector's cleaned put a 2.5 half exhaust system on B&M short shift kit made my own intake,MSD 8.5 wires and Masterblaster coil,NGK plugs.Wow what a made change this did to my car.What would be the next best thing I should do to get more "HP" P.S alittle note to self when doing a rebuild,ALWASYS have another car u can drive before the rebuild because if u don't your going to hate been home all the time.I fogot one,I also put a eletric fan on car.

[quick]

I recommend you check out the forums at celicasupra.com

[Import_Eve]

Is there a list of parts that you need to turbo the 5mge.

[formulaone]

what internal parts are out their for a 5mge engine that will help out the longevity of the tubo engine
so what im saying is im rebuilding my 5mge engine and am wondering what internals will help me out with a turbo kit installed

[williamb82]

forged pistons and a 7mgte mhg with arp studs. all available at rabidchimp.com

[formulaone]

well my supra is running in pretty top notch right now and im looking to put on an exhaust system i was thinking of a dual greaddy or hks mufflers with 2.5 inch mandrel pipes all the way to the downpipe gasget. the only question i have is how do i keep my resonation to a minnimum but still have nice sound and performance to it?

This is not even close too right. I ran 12 psi on a 10:1 RRFPR for over a year with no problems. The car was run at SP performance and the RRFPR was working well within the needed area. I think I could have gone to almost 15 psi without changing of the unit. Where did you ever get that 7 psi number from?

I've been debating about whether I should drop a 7M into my '82 or if I should rebuild and turbo my 5M.

My 5M has 291k miles on it and still runs great, but I ain't tryin to add boost into the equation

My mechanic hates the 5M and has been pushing me to find a 7M

[Jakespeeds]

If you stay with a stock engine, you couldn't add much in the way of boost...

You'd have to change the pistons at the very least to get anything from the motor...

I have found it to be completely the opposite. 300 on stock internals is doable and has been done. Doing it would help with experince.

Yes its doable but for how long? And is it really worth your time? The person that had my car before me built my 5m (8.5cr pistons 6 angle valve job head fully decked arp headstuds/main studs etc.) and he spent thousands of dollars on it. And now whats cool about this engine is that other things would give out before my engine does by throwing more power at it (tranny, possibly diff). There is nothing like the feeling of knowing that you dont have to worry about something in the future if you do it right the first time
