Hi Guys, got a question !, is it possible to put 2 turbos that came from 2.3 liters dodge omni engines ??? I'm able to fabricate the whole setup.

you see, I got a 5.7 lt1 engine that I swapped few months ago ... I deffenitly want to turbo charge the whole thing.

How much boost can a small turbo like that creates ???


Thanks and have a merry christmas

 

I am by no means a turbo expert, let me set that straight first, But I do deal with quite a bit of turbo engines here in Japan.

The easiest way to determine if a turbo will fit your appplication from another vehicle is to look at the displacement of the donor engine.

For example you are looking at Ford 2.3 applications (SVO mustang, and Thunderbird turbo coupe) Take the displacement of the engine they were on (2.3) and multiply it by the number of Turbos.

2.3 x 2 = 4.6

your 5.7 is a little larger than the "sweet" area of the turbos. On a V8 application you have to look at the engine as 2, 4 cylinders and size the turbos accordingly.

Turbos are designed with flow maps. This is another thing you have to consider. The Turbo has a useable area of RPM below that and you don't use the turbos potential, above it and you lose the efficiency of the turbo to excess heat.

Example

I have a Garret T-28 on my Nissan Skyline from the factory, useable RPM range on it is 2200-8000 RPM, the car redlines @ 7200 @ 14 lbs of boost. Above that boost level and the turbo suffers from Heat soak, so I upgraded to a HKS GT 2535 ball bearing unit. Useable RPM changed to 2400-9000 RPM, and has the ability to produce 20 lbs of boost efficiently Not much bigger as far as size is concerned but the compressor housing and wheel are slightly larger.

There is a website in Austrailia that has a calculator you might want to look at to give you a ball park estimate of what turbo to use with your application. http://www.turbofast.com.au/TFmatch.html

This is by no means the final answer, many folks have bolted on different turbos for their needs. But you might want to do a little more research into the units your looking at.

A few places I would call with your questions:

http://www.turbochargers.com (Texas Turbo rebuilds)
http://www.turboneticsinc.com/ (Turbonetics Inc.)
http://www.majesticturbo.com/ (Majestic of Florida)

All of these folks are Experts and can answer your specific questions far better than any I have seen, all have great customer service representitives and are willing to help anyone.

Good luck

Exactly what I wanted to know , Thanks

 

I have seen many people build similar setups using 2.2 and 2.5(even better) chrysler and 2.3 ford turbos and they all seem to have significant power gains and work well compared to no turbo. ive never seen anyone use two 3.8 turbo v6 regal turbos (3.8x2=7.6liters or 459.1 cubic inches) wow think of the implications of a twin turbo 454 BB chev!
