Post Can I put another turbo to make WRX a twin turbo

Can I put another turbo/supercharger to make WRX a twin turbo?
Will it be faster?

U dont want to do that. For one, it would cost an arm and a leg, and 2 you can just upgrade that engine with a bigger turbo and some extra goodies and be just as fast.

Generally, we do not like to TT a 4 cilynder. TT's are usually done on inline 6's in Japan. There are not to many V6's over there except the TT Z32 Fairlaidy. 4's do not build the kind of exhaust manifold pressure to spin up 2 turbo's in a efficient fashion. You could do it, but it would Like the last man said, go with an upraded turbo (Ball bearing type), a bigger intercooler, bigger injecters, and a custom ECU that is mapped to your engine. You will be ripping mad $hit up.

The Legacy B4RSK has a twin turbo EJ20. Being the not so proud owner of a 3rd Gen RX7, I can assure you that you want to avoid having 2 turbos if at all possible. Spend your money on a larger, ball bearing turbo if you need more boost and less lag.

i dont see why you would want to do that it would cost so much money also there will be more moving parts which means there is a more likely hood of something breaking or malfunction. if you were to upgrade your turbo why not just go with a bigger ball bearing turbo. many people with tt's switch to singles because they can get rid of turbo lag with a programmable ecu and boost controlers and still keep high end power. seems like a waste of money and time.
peace

There's a MY00 WRX here in Australia with a custom twin turbo set up and Motec M8 Pro ECU with 410hp at the wheels. So to answer your question.. yes it can be done.. and if it's done properly.. yes it will be fast.

Well, I was just speaking from my experience in Japan. I know that the B4RSK is a tt, and a Bad Ass one at that. I would like you to know, however, that there are very very very very few pick ups in Japan, and I have no clue about the Tacoma. Sorry.

what about a supercharger running in conjuntion w/ the turbo?-Lancia did this on their S4 Delta rallycar...talk about engineering!...wonder if any "fast road" street cars have ever had this done?...hmmm,i guess the quickest & easiest way to destroy stock engine internals would be nitrous?

+ A rediculously low spool turbo and you are in heaven.

I always wondered about adding a SuperCharger. A roots charger mounted where the alternator is and swap the A/C with the alternator(if the 2 can swap). Theres an extra pulley mounted to a solenoid that when the turbo reaches a set boost, the solenoid kicks in and releases tension on the SC so the boost from the 2 forced induction systems don't boost spike/destroy motor.

I would never do it myself, but its just an idea.

if twin turboing an EJ20 I would go with two GT12 ball bearing turbos being I can get them for free/cheap...made for 500-1000cc bikes...so I'm figuring two of them on a EJ20 wouldn't be lagy and would have a good powerband because they are designed to rev up so high...showing peak power and torque on 600 cc bikes at about 5500-12000 rpm ( in about 400 rpm incrememtns) depending on the tune...

I agree with running two turbos in parallel but what about in series? My limited memory thinks I read that tt in series produce some wild boost.

Isn't the whole idea smaller turbo for low RPM and bigger for high rpm in a TT setup?

Yes you can, but you will be wasting 3 things: money, time, and reliability.
