Hey im new at this and am looking to buy an evo but this is just a question i wasnt expecting to buy one but would it be possible to get a twin turbo for the evo?... if not buy one would it be possible to get one custom made?

sorry man. You need more cyclinders to push the turbos unless you get really small ones. =)

Anything is possible if you got the money.

for he cost of it, it wouldn't be worth putting twin turbo's... its liek putting 6 turbo's on a chevy.. why...... You could fabricate a twin turbo setup using very small turbos up to some mid sized turbines but low rpm's would really lag.. imagine what u have now taking at least twice as long to spool up or react. Plus plumbing all of this stuff would really be rough. I would say the only guy running twins on an evo is doign it for looks. The other way of running twins is how the diesels guys are doing it but the layout on the drivetrain wouldn't support this etup as it requires alot of room, and generates alot of heat. Plus the evo motor can't handle that kind of PSI. I'm not too sure how effective two smaller turbo's in that kind of layout would perform

As far as I understand it, the point of a twin turbo setup is mainly to reduce lag - either with sequential turbos (small turbo spools up quick for low end, bigger one spools up later for top end), or in parallel (two smaller turbos that spool up quicker, each feeding of half your cylinders, instead of one bigger one feeding of all cylinders). For a 4 cylinder engine a parallel is probably not a good idea (2 cylinders don't have enough displacement to push any reasonably sized turbo). A sequential setup could be interesting, but you will probably run into engine room constraints with all the piping etc.

Also note that there is no proven 2.0L 4-cylinder twin-turbo setup available out there, so the turbos you choose may or may not work. So if you're gonna take on this project, you'll be doing all the R&D for it. You're most likely going to have to go through a few iterations on a project like this in order to get it working decently. All of this is going to cost you $$$. Why spend all this time and effort on a setup that may not work when there are plenty of proven turbo kits out there?

It is not worth it, even if you totally designed a set up and built the motor up it would be a waste of time and money due to space in the engine bay.

Sure you could run 2 small turbos but why in the world would you want to do that?

Just stick with what this whole world of the 4g63 has known and stick with the single.

uhm... it's not just that it's a waste of time and money... the setup would suck. even if you got small turbines that were able to be pushed by 2 cylinders your boost would fall flat on its face way before the stock turbine does. and if you went any bigger you'd be waiting for spool for way longer than the stock turbine (which negates the point of running twins).

Don't double penetrate the evo. She's too classy. (and its only 1997cc so two cylinders wouldnt push 2 turbos efficiently, its all covered in the above posts)

The subaru legacy/liberty b4 is a 2.0 ltr boxer 4 cyclinder twin turbo and the power delivery is super smooth. It know the setup is more ideal since because of its boxer setup but dont say things you cant back up... or you dont know...

you could put a supercharger with a turbocharger or twin turbo on your 4 banger if you want.

most people just do it to get rid of the lag, sequential turbo. I don't think you'll gain much from it tho.

here is a cool 4 cylinder twin turbo. http://www.bobnorwood.com/Max-4%20Home.htm i bet it is faster then most (if not all) single turbo 4 cylinder cars in existance. the webpage is maybe a little outdated because i have seen the car run on a speed channel special on drag racing. it is very. very fast.

but yeah, the evo is not going to have twin turbos. at least not for anything your going to be doing with it.

But they have now gona back to a single turbo and the car is so much more better now
It even makes its peak torque sooner and every review of it says its a lot better than the old twin turbo setup which everyone complained about the lag between the switch over point for the turbo's.
