ok well i jsut came up with 3 eclipse/talon turbos, 2 are 14lbs from the same year eclipse and 1 is from a different year.

im building a 85 corvette TPI 350 l98 and so b4 i drop the motor in i wanna get some opinions and get some questions answered.

1. Will these turbos even work on that motor?
2. Single or double? (i dont really care about the amount of work and kinda like the fact that i can say its TT, it also evens out the look of the motor)
3. who wants to change my fuel pump? (haha j/k)

i think thats it for now.

 

Are you trying to say that they are Mitsi. 14s, or that they weigh 14lbs?
It isn't a matter of if they would work. It is how well they would work. A first guess would be that 2 would be OK, but 4 of those would be a lot better. If it were me, I would run two in parallel on each engine bank. You might try running just two to start out, but try to lay it out so you can add two more later on if it seems like it isn't enough. Or you could sell those turbos and get something more suitable (it depends on what you want for spooling range and HP).

You may want to state what that engine actually has in it for parts, CR, intake, etc if you want a better answer. You might want to include what kind of engine performance you want with the turbos on it.

Single with the turbos you listed= no way, doubles=OK, quad=good HP

After you get done fabbing stuff for 4 turbos changing the fuel pump will seems like a five minute job.

 

I think he means 14b turbos. It doesn't really matter though, because 2 of those turbos will be too small for a 350. Also, 4 turbos in a camaro is impractical unless you have a lot of money (since you need 4 of everything) and a lot of room in your engine bay.

My advice is to sell those turbos and buy a single or doubles that will work for your engine.

 

this is all that he said i am getting....

There 2 14b eclipse turbos with o2 housings, 2 eclipse
intercoolers, 1 eclipse blow off valve on a stock 2"
pipe, 2 downpipes that come off the o2 housings that
have about 6 inches of 2" diameter piping, oil and
coolant lines for the turbos that just bolt to the
turbo(you'll have to run oil feed lines to them from
some part of the engine, i used that little plug above
the timing cover, it had plenty of oil pressure.), a
smaller coolant bottle, a joe P manual boost
controller, a walbro 255lph High Pressure fuel pump, 2
turbo oulet elbows that mount on the turbo itself, 2
exhaust flanges that have 2" diameter piping that can
be bolted to the exhaust side of the turbos so you can
just run a straight pipe to it and weld it up.

oh and the motor is gonna be stock lower end of the motor is gonna be. stock iron heads but new valve job and resurfacing gonna put some new lifters etc. found out that comp cams makes a TPI cam and possible lifter set for turbos. ported intake manifold, stock runners so far, ported plenum, 24lbs injectors possible msd unit.not sure what else at the moment

dont wanna make too much power jsut enuff to get her slideways. (drifting)

 

Sell those and get a or a pair of turbos more suitable for the application. The 14B was almost too small for the stock Mitsu engine.

Most guys will run a pair of T3 or T3/4 hybrids on the 300ish cu in. engines.

has anybody personally tried these turbos on there cars?

 

You could keep asking and keep getting the same answers, or you could waste your time and try it yourself.

If you only want to rev to say ~4000rpm max, they'll be good turbos if you use both. Make sure you set your rev limiter far below stock redline or you'll be picking up pieces of the turbos and your engine internals before too long.

The exhaust housings are tiny for anything resembling real displacement, they'd make power really early and then cause a huge exhaust restriction up top, and then overspin to the moon. IF the exhaust sides were a lot bigger then the compressor sides would be somewhat okay for small boost and very mild power, but they aren't. 1G DSM guys can get decent power out of them when they stress them to the max, but the exhaust sides are still too small for that, on a 2 liter let alone 2.5 liters.

If you are going to do a JY turbo setup, get bigger turbos and keep all those extra DSM parts you have because you might be able to use some of them.

 

ill tell you a short story to try to help you
when i first started into cars about (7 yrs ago) i hade the drive to make power but no reasurch to help me out or lurn from, my first test mule was my friends sbc 305 truck, we installed 1 t3 from a sabb on the truck, it hurt the truck so bad!!! he didnt get any boost in any gear but 5th, not because the turbo was way to big for the truck but because the turbo was way to small, that poor turbo didnt flow enought air to feed the motor (we were lucky the turbo didnt come apart) the truck was put on a dyno and the out put of the 305 with a 3ed gear pull was 124 hp at the wheels. totle cost for that 124 hp was around 400$$ (piping, turbo, oil piping, grinding disks and cut off wheels) if anything dump the dsm turbos and run it na for a little and look for some better jy turbos

do what you will
p.s i like your rims

 

Go single turbo... big fat single turbo. Yeah by far it will be harder to plumb, but then, think about it. v8 torque is tough to handle off the line, right? well a big turbo will sap some low end power while it struggles to spool. But you have 300-355 cubic inches of air spooling it so lag wont be that bad, and by the time the turbo starts kicking ***, you'll be rolling and traction wont be an issue. Plus a big turbo leaves lots of room to increase the boost as your motor evolves into more of a turbo motor. It'll also be easier to plumb the intercooler.
