Will Mitsubishi TE04H turbos work with a V8? pics!

First of all I wanted to say Im so glad a Dodge board like this exsts! K-cars have always been interesting to me. Id love to have one as a project some day.

Ive got a 1986 Mustang thats been converted over to carburetion. Other than that its basically a stock engine with 200-225hp...very mild 302. Ive decided to run some junkyard twin turbos on it for fun. Just a little project Im doing for under $600.
Ive got basically every part of it figured out, but Im not 100% sure what turbos to use yet and was looking for some advice from the Dodge crowd who has dealt wiht these turbos alot. No one on the turbo mustang board has any info.

I had bought one IHI turbo from a Turbocoupe on Ebay for about $100 with shipping. Went to the junkyard the following weekend and found two of the mitsu teo4h turbos in great shape. Took like 4 hours to get them(being on the back of the engines). I paid $120 for them and theres no shaft play. One even looks re-built. Both in excellent shape.

My only concern is that the mitsu teo4h turbos may be too small, even for a mild 302. Although, people say the smae about the IHIs from turbocoupes, and as far as I can tell theyre perfect for stock 302 engines. Someone is running 10.9 with them on a stock 87-93 Stang. Probaly the fastest stock stang turbo time.
So Ive been trying to compare the teo4h with the IHI to decide what to go with. The look very similar in size.

The main differences I can tell is that the "blades" are shaped differently. Which blade design is more ideal to have? Also the exhuast side of the TE04H is incredibly small. Would be pretty difficult for an engine to exhale through I think lol. But turbos spool alot based on exhaust temperature, wave, flow etc..So is it really a big impact? The IHI one isnt exaclt large either, but theres a bit of a difference as you can see in the pics.

The idea im leaning towards now is to use the Mitsu teo4h's because I already have them and theyre in great shape. Would take a while to find an IHI in the junkyard, and be more expensive to get another on Ebay. Im considering just making the exhaust flanges in a way so that the teo4h and the IHI will bolt right up incase the mitsus are too small I can upgrade without too much work. The flanges look similiar. I think I coudl make that work.

And BTW I plan on running them through 2 turbocoupe intercoolers, then connecting them at a Y pipe after the coolers, then to the carb bonnet. I know its not ideal to run 2 of them, but this is just a cheap junkyard project . Will those intercoolers be good with these turbos?

Sorry this was so long! Just want to get more opinions before I dive in and do so much work. Any input is GREATLY appreciated!

They'd be perfect if you ran 1 on every 2 cylinders. But if you're gonna run two you really need at least the 84-87 T1 garretts. New turbo options that would work well would be a couple Super60 Turbos with .63 a/r housings. Or maybe a single GT series. But you're on a budget. I think you got jipped on the prices for the turbo's considering you had to pull them yourself. Our U-pull-it yard charges $16 for a turbo. There's a couple guys around here running J-yard setups on their mudstains. They're fast. But the setups are really not ideal. With some good head porting, a couple or one real turbo and good exhaust. Not some crush bent pipe they all like to run around here they could probably go a hell of a lot faster. Still rednecks though thinking you have to have backpressure and all that crap. They don't understand how thier fuel system works and don't want to learn.


Later

Yea Ive been reading alot about other people getting turbos for much less at their junkyards Im going to a different junkyard tomorrow. If theyre decent priced Ill buy another IHI(if I can find one) and maybe run those and just return the mitsubishis.

Ive got my fuel system/carb everything all set with some help from turbomustangs.com.

I wish I could find someone else who has tried these mitsus on a 302 so I woudlnt have to be the guinea pig . Im gonna go to the garage and see if I can get measurements of the exhaust and compressors...

[GLHNSLHT2]

Well the Mitsu's were used on our 2.5 motors. They were way too small. They spooled good but are way to small for that motor stock. Any upgrades to the exhaust and the boost starts to cheep uncontrollably. Basically you have two 2.5 motors The 84-87 Garretts should be plentiful at the J-yard. I think the IHI's from what I've heard about them are too small too. They will work, but your top end will suffer, and you might not be able to control boost if your exhaust is good. Just something to think about

Im running 2.5 in exhaust with cats and summit turbo mufflers.

Well I went out to measure the exhaust differences and had some interesting results. The Exhausts on the dodges are not the same. One is just slightly larger then the other. Was there a difference on the Te04H's over the years? How great of a difference is this with regards to performance? Its just a tiny difference I guess, but sucks .

Heres some pics..In the slightly larger one(2nd pic) the ruler fits all the way through. I cant get it through the smaller one at all...








Ill see what I find at the junkyard. Maybe I can find 2 of the older dodge ones in good shape. I think I saw one at the junkyard I got these at, but the shaft wobbled terribly. Just all the work that sucks.. Im gonna hve 10 of them before I have 2 mathcing ones that work

1) You are going to try and run this twin turbo set up through a carb? Why not switch back to FI??? Really what can you run 5-6 psi tops blowing through the carb??

2) Why would you want to run boost period on the 1986 flat top pistons and crappy truck heads?

3) The factory teo4h turbos are tiny.....they don't work on a 2.5L dodge, will they work on a 5.0 Mustang???

You can run as much PSI through a carb as through EFI dude. Use nytrophyl floats. Heres a good article on rebuidling a double pumper for boost: http://www.turbomustangs.com/forums/...&threadid=7810

I want to run boost beacuse I want to make my car faster and I can do this for about the same price as new pistons and used Gt-40 heads, cam. Which would put me at the best.. 13s?.. Someone on the turbo mustnag board is running 10.9 with a pair of IHIs. All else stock. Turbos are the cheapest route to horsepower for me, and Ive always loved turbos. Not too many V8 owners do this and every setup is a little different making it unique, fast, and increase the sales value. And at the same time having somethign fun to wrench on

I guess im just gonna go with IHIs since theyve been tested by someone before.

Was such a nice day out figured Id dive in Flipped the headers over..Everythign looking nice. The dipstick had to be pulled out..Ill just bend a different curve in it to go around/through the header. The GM HEI module is kinda in the way.. may mount it off to the side. Power steering and alternator doesnt really look liek an issue.
I grabbed those exhaust pipes out of the junkyard last weekend thinking they coudl be of use. Looks like theyll work to hook the turbos to..just need to be trimmed down obviously.
Gonna searh for some E5 heads at the junkyard tomorrow.

Cant wait to start the welding and really get things in place

Believe it or not, I think the twin mitsus are an ok choice if you are planning on running up to 14psi. If you're planning on more than 14 psi, then you better have some solid hardware to hold that much power.

If you find that the Mitsus are too small, you can also find lots of t3 turbos which will bolt righ in place of the Mitsus.

I happen to run twin Mitsus in my 2.5 liter 4cyl, but I'm running 30psi of boost. Since you already have the 2 Mitsu's go for it.

If you want to make more than 500hp go for some bigger turbos.

[88lebaron]

When you think about it though the mitsu's should be fine. They used the mitsu's on 2.5's with 7-9 PSI (which is probably more then enough that his motor will handle without lower CR and some forged crap.) so 2 turbos good enough for a 153 should be good anough for a 302 since its less displacement then 2 2.5's.

im so confused

I think my mitsus are mismatched. one has aslightly larger exhaust port than the other. What does that mean? coudl they still work not being matched correctly?
thanks

[Mike B.]

I say "go for it." Some people have run the mitsu's at 18 psi but they are very innefficient at that pressure. Are you planning on intercooling? I would if I were you. It will definitely help.

I didn't know about the different exhaust sizes on the mitsu's either--but there's a lot I don't know. Do you remember what cars you got the turbos from?

hmmm Well I think Ill go for it! Im obviosuly not looking for a ton of boost. under 10psi. I think these will be ok.. I can always sell these and upgrade later if theyre complete trash like some say.
I will be running 2 turbocoupe intercoolers with them.

Anyone have any info on the exhaust differences? Id like to have that figured out before I have the green light. Thanks.

[88lebaron]

U running sequential with one carb? or true dual with 2 seperate intakes/carbs for each intake?

1 turbo for each exhust side going to the same carb hat and carb. I may run a dual snorkel carb hat though if I can make it work, but doubtful.
I think having dual carbs with twin turbos would be a cool idea though!

[Aries_Turbo]

yeah go for the mitsus. you gotta make all the stuff anyway to support them.... if they are too small then go for the older garretts. they will bolt in as a replacements. i wouldnt worry bout the exhaust being a little smaller on the one. youre gonna parallel the intake pipes after the intercoolers anyway to go to the carb so take your manifold pressure reference after the "t". with those mitsus youll have basically instant boost. youll have to really watch for creep in the higher gears. there is about enough airflow there for 500hp if you max those little puppies out. much more than that and youll crack your block anyway. using the dodge numbers as a reference youll prolly be able to make and easy 400hp and well over 500hp with those little buggers. lol. good luck and let us know how it goes.
