Twin turbo 3.0L project back on!!!

[mwinkle353]

Finnaly found a compressor map for the IHI turbos. Now I can be at ease with my twin turbo project, and ditch the single turbo setup idea.

IHI RHB5 VJ11: Ford Probe/Mazda MX-6

IHI RHB5 VJ17: Ford Mustang/Thunderbird

Since I'm planning to use two on a 3.0L V6, The fist one will just get the job done. The second one, will be used if I get the motor massively worked on. Meaning if I get the heads opened up really well and I find a decent stroker kit.

Both turbos are good to about 15-18 psi of boost. They seem to taper off above that in effeciency. But, since I'm not looking to run more than 15psi on my motor, these will fit the niche quite nicely.

Awesome Wink!! Best of luck to you with this project. Keep us updated with pics.

[mwinkle353]

Oh you bet I will. I'll be screaming and the whole east coast will hear it when it's done!!!

By the way, does anyone need a rebuilt T3?

Droooling...

Ummmm, rebuilt T3 ready to drop in?

Is it small enough to go behind the plenum?

[mwinkle353]

It's a Ford turbo. Won't bolt in on a Chrysler manifold. But you can use the Chrysler turbine housing and just install this unit into it.

It's a 60 trim compressor in a .60 A/R housing with a Stage I turbine in a .63 A/R housing.

PM me if needed, as to not hijack the thread too badly.

Can't you use the 3.5l 6G74 DOHC crank in the 3.0l for a stroker, i remember seeing something about it over at 3SI. Might have to shave a bit of the block to rotate without hitting anything. I was also wondering if the connecting rods from the TT/VR-4 was the same deminsions of the SOHC rods, they could have more spacing for the oil jets though.

With the 3.5l you probably need different deminsion rods/pistons though.

So u would have a be able to cyro the 3.5l and use the TT/VR-4 rods, and just need some sturdy pistons. I'd love to see a 3.1l SOHC Turbo/SC stroker!

3.1+L only requires a big overbore.

BTW, the 3.0 block can be made to 3.7L with a custom crank. Ray Panpena is getting that project together. After that he is stroking the 3.5L to 4.5L.

That car is sick I've been to their shop a few times

The VJ11 is a better match and allows for growth. I just added these to my turbo calculator.

As long as the 3.0L is kept to under 15 psi, those turbos have much room for growth. But the VJ17 from the Thunderbird would be a great match for a motor that has had much headwork/cams that increase the VE's above 5k rpms.

Right now, my calculations put me into the right hand part of the 73% island at max power on the VJ11 compressor at 15 psi. At 10 psi, it's sitting on the far right side of the 75% island at max power.

I also like the VJ11 unit better than the VJ17 due to the fact that it will actually allow the 3.0L motor to run up to 22psi. Where the VJ17 is supposed to run out of steam above 160,000 rpms turbine speed. And that would equate to about 17 psi on a highly modified motor.


I like the fact, that with either unit, they have really fat flow ranges in the middle pressure ratios.


Glad to have helped towards the calc,

He cant even make a run down the strip. his car is too heavy and he is making Well over 800awhp. breaks his drivetrain every time.
Not sure if he is a good driver, or is preloading the drivetrain before dropping the hammer.

Im pretty sure if he puts a 4.5 into his car, he will be making 1200-1300+awhp with ease. No way that will make a clean run down the track...


Wink, I think it would be awesome to see your car with true dual side exits.

I had thought about it. But then the ignorance left my head on that subject. I figure that I'd have to have the front and rear combine in at least one place to get a good reading on the O2 sensor. I'd really hate to have an injector or two go lean and not be read by the O2 sensor.

Just to let you know, I was actually looking into running sidepipes like the old corvettes.

[Ondonti]

x pipe it then o2 there :P

[mwinkle353]

You've read my mind. I was looking at Magnaflow's X-pipes and was seriously thinking about it. But I'll be damned if I didn't already have the 3" cat and pipes. (unless someone else wants to purchase them from me?)

I started welding my rear manifold for the install of my twin turbo install. Let me tell you this....... I'm by no means a welder at all.

The welds looke like birdshit. But they penetrate all the way through to the other side without undercutting the outlying material.

I'll get pics up when I get another spool of welding wire and complete the main welds of the manifold.


Ok here are the pathetic weld pics.
