could I put a turbo out of like a diesel in my rx7? I just made a GIANT ported motor... and i think a turbo would be nice for this NA.
There is a junkyard for everything from busses to semi's not too far south of where I live (Gardner, KS is about where it is, if anyone cares). I'm sure I could buy a turbocharger for cheap, and I was wondering how I could make that work, or if its at all possible. I wanna keep this thread in the FC section bcuz i DONT WANNA MAKE A RACE CAR. yet.
EDIT: I'm dead ****** serious... in theory, if there was a way to control the airflow this could work very well. Staying within my immediate family I have access to a machine shop and everything I would need. Please help if you can at all...

 

Diesel turbos are for diesels for a reason. Diesel engines don't need compressor bypass valves(blowoff, Wastegate) don't ask me to explain why not, I don't know for sure. But the point is it isn't going to work well.

If you really want to go beyond the T-88 point I suggest you give John Urist a call. I won't post his number but if you are crazy enough to think your motor can spool something beyond T-88 you can PM me. For the record John Urist builds some of the fastest "streetable" mustangs out there. he is testing on a car that runs a 112mm turbo (see T-112) The 6.0liter firebreathing engine it's strapped onto couldn't spool it for the launch, so now the car launches under nitrous.

 

I don't necessarily want to do that, I want to make a streetable turbo like that. I can install a BOV somehow I'm sure... heck, this is my 3rd NA/Turbo... these cars are my life...
This car is built so it can handle high boost applications, but I need a way to control airflow. I need something similar to a wastegate or SOMETHING. I plan on getting a boost controller and all that. I just wanna know if theres a way to make it streetable. Airflow control.

 

Something like a wastegate?

You mean, like, a, wastegate?

Why not just buy one? or am I missing something real obvious here?

Diesel turbo's typically have a smaller turbine section than the compressor section.
This combination isn't very conducive to having a powerful turbo-charged rotary.

You could do this, but if you want it 'streetable' Why not just get a hi-flow S5 turbo? or a T04 with appropriatly sized turbine?

Much less of a head-**** and much better suited to the application.

 

bcuz i can get these turboes for like $50 lol
lets see... what cars have big turboes on um? anybody know?
i might go with an s5 turbo and ported wastegate i guess... that just seems so inappropriate... i might look for a wrecked eclipse too... BUT THEN I STILL NEED AN IC OH HELL... hmmm...

 

careful man..those things run HIGH BOOST like i seen deisel turbos running on lower levels of 20 psi......and like you could buy a compresson rebuild kit and get you up to like 36 psi....tahts ALOT of boost the waste gate is intergrated into the side of the exhuast housing and isnt a huge wastegate like on small normal turbo cars.....bow im not totally 10923719837297% sure but i pretty much have my facts striat.....

 

You'd be VERY hard pressed to find a stock production car with a bigger turbo than a stock S5 one.

The new BA Ford Falcon turbo 4ltr 6cyl is the only one that comes to my mind...


and just because you can get a turbo for $50 doesn't mean it will work at all...
not only that but then you need to factor in a manifold, aftermarket ECU of some sort, bigger injetors, exhaust setup...
just to name a very quick few.

 

20 psi thsi car can handle
or i could get a boost controller...
I just wanna know if I can use one and hook it up to my car and have the car live to see tomorrow... I'm more concerned with too high of airflow entering the engine and causing the shaft or possibly a rotor to leave the engine bay... well maybe not that bad... but I need my apex seals to last for a lil bit...
So I'd have to pull the wastegate out of the header of it? could i buy a wastegate and would that work?

 

No, sorry, not really right, maybe on one particular car, yes..

Wategate setup is very dependant on the car its comming from.

And just because the turbo is producing a particular ammount of boost on that diesel engine, does not mean it will produce anywhere near a similar ammount of boost on a 13b, either way, this is controlled by the wastegate. (max boost that is.)

 

well cool then i dont mind being wrong at all now i know and knowing is half the battle..... : )

 

wastegate controls amount of air... not necessarily boost... i know this fo sho... i blew a motor cuz of this...
but if I got the stock setup from a mack truck lets say... could I stick it on there and not kill my engine?

 

Sorry, your wrong...

The wastegate does indeed control the ammount of boost.

Unless it is too small, as is the case of both S4 and 5 turbo's when mated to a 13b.
This is possibly what your problem was.

However a wastegate most certainly controls the ammount of boost..

and no, you'd blow your engine..

Unless you've got some very serious fuel modifications and an aftermarket computer. Then the skys the limit really.

 

Umm...does anyone else notice where the guys says he wants "streetable"? I'm going to go out on a limb here and say, that's not possible with something that large. I really don't think the rotary engine will make it spool fast enough to even be worth it.

 

THANKS
okay what about a mitsu turbo? would that "bolt on"? how do it compare to a stock S4/5 turbo? I've never upgraded a compressor... i usually just play with NA's... LoL im movin up...

 

Like I said, you'd be very hard pressed to find something bigger than a S5 turbo stock.

Nothing will 'bolt-on' at all, hell even S4 and 5 turbo's aren't interchangable.

and since your wanting to bolt it onto your N/A engine, thats a whole different kettle of fish. Mainly due to the computer.

What kind of money/power are you looking for/at here?

 

okay no ****** **** i've done NA/turbo conversions before, but i meant somethin where i wont have to buy a whole bunch of other **** to make it work.
I was just wonderin if those would work bcuz i can get um cheap LoL...
Im j/c how a mitsu turbo compares to a S5 turbo.
And could I just stick a mitsu turbo on there? WHILE DOING ALL THE MODS REQUIRED FOR ANY TURBO? I just wanna no if i gotta do anythang special...

 

Dude, I already said it wont 'bolt-on'.

If you done it all before why ask? a turbo is just a turbo, nothing special about any of them.

All that changes is where it bolts to the manifold/down pipe.

and like i said, and i'll say it again, there isn't any other turbo that will 'bolt-on'.

There was a HT-20s turbo, off a diesel truck that APPARENTLY bolts on to the manifold, not the down pipe.
But that is only hearsay, I can't find any info on the turbo, and it's got a smaller compressor than a hi-flow S5 turbo anyway, from what I saw anyway.

 

Look, just because you've done NA to turbo conversion does not make you a turbo expert. The fact that you're asking questions in this threads already implies you don't know what you doing.

Before you go off on me, here's the answers you've been looking for...

Turbo sizing is dictated by exhaust flow. The turbo is dependent on exhaust flow. This is how you size the turbo (turbine) side of things. You'd be lucky to pick a "$50" turbo from a pile and expect it to work. There is a proper way to size turbos for the 13B engine. We cannot tell you which of your $50 turbos will work unless you start popping off housing and start measuring compressor and turbine wheels.

If you're running an NA engine, you either have a 9.4:1 or 9.7:1 compression engine if it's from an FC3S. You are not going to get 20psi or reliable boost, unless we're talking ultra-high octane race gas or an expensive aftermarket stand-alone EMS to control fuel and spark.

Mazda uses a proprietary turbine exhast flange inlet design on their Hitachi turbos. This means NOBODY ELSES TURBO WILL BOLT ON. Get this in your head. If you want to stuff another turbo from another car onto the stock manifold, you need to make an adapter plate or build a totally new turbo exhaust manifold. If you can weld, this should not be a problem for you. If you got resources to do this, you can put whatever turbo you want on your engine.

Just because you can stuff another turbo into your motor, that doesn't mean it's matched well. I'm not going to get into a dissertation into turbo matching for the 13B, as I think you really don't care about that; it sounds you just want to do it just because you think you can. Good luck.
