The title says it all. I'm real curious if it's possible or not. Is there such thing as twin turbos for EVOs? If so which brand creates them? I've never heard or seen an EVO that's twin turboed. If anyone knows of any sites link it up please Thanks.

 

Not enough exhaust gas to spool any size turbo worth putting in the car. Not to mention they won't be efficient at even stock boost levels. Plus it would be an expensive manifold and space becomes an issue. It is too easy to make a fast single turbo Evo's to even consider wanting to go TT.

 

Anything is possible!! with the right amount of $$$$$$$$!!!!!

 

there is no good reason to do twin turbos on an evo

 

Cosmo, (forgot his SN -sponsored Blue Evo 8 GSR -Devo Tuning car), a while back had a custom TT kit Adam made for him, he ended up selling it.

 

Maybe two small 16g's. I don't think it's worth the money or time.

 

There's just no point. If it were worth having 2, the supra guys wouldn't switch to a single. Now if you had a V8 on the other hand...

 

it can be very successful if done correctly. there was toyota 2.0 with twin turbos in SCC 6 or 7 years ago that went 9.60s in the quarter. car was built in japan if I remember correctly. that was back when it wasn't easy to get in the 9s

 

two motors, each turbo'd. that would cool if someone did it in an evo

 

Like was said previously, there really is no point in twin turboing a 4 cyclinder engine. I've found sources of it being done on a few subarus- usually full-race cars where they need quick spool and big top-end, but for an everyday evo, just not worth it.

And the Supra guys switched to singles for the massive amounts of power generated with a single. They could do it with twins, but it wouldn't be as effective plus alot more complicated than a large single setup.

Have you ever seen big single-turbo supras road-race? Probably not, because that big snail is relatively pointless unless its on a straightaway. But for corner carving, auto-xing, gymkhana, etc, you'll see that most owners who do those types of events stay with a twin setup as its more efficient than having to deal with the Lag generated by a larger system.

 

The only thought I had a while ago, and I forget who I pmed in a drunken state about it is this:

If you had one VERY small turbo that would spool almost instantly and run out of steam, and electronically had wastegates open and close the pathes to each turbo based on spool time.

So one small turbo run from 1500k-4500k, then a gt37 or larger turbo have the exhaust gases diverted directly from the small turbo (bypassing each individually at different times so only one runs at a time) to the large turbo to make high HP.

Its a crackpot idea that would be so heavy, it wouldnt matter what kind of numbers it made....spool or not once a well tuned car kicked the turbo in, it'd take off while my idea would spend its time "changing turbos"

Just a thought though.

 

Its possible, but not really worth it...maybe if you had two engines, one 4G63 in the front, and one in the rear, like the twin engine DSM that someone made a while back. The extra weight would offset any advantages gained in the power curve.

 

for almost no advantage the twin setup would be too complicated and costly. single ftw

 

I don't know about this set-up though

 

looks like something norris designs came up with....exhaust up over the front of the motor and out the left side of the car....doesnt look like a twin though
