Default Twin turbo?

I tried searching but it came up with alot of single turbo forums. So has anyone twin turboed a tC or do they just go with one giant turbo? Whats the biggest turbo someone put on their tC and it not being drag car? Can the tC engine handle a twin turbo? If you got pics please post them. Thanks

Twin turbo on a large displacement 4 cylinder would have problems spooling. I was actually thinking a twin turbo setup like on the '80s model GPZ's might work, but the tC motor wouldn't be able to turn the RPM's that a 750cc would. Just a random thought from me, since I am not turbo knowledgeable.

twin turbo setups are usually ineffective, especially on 4 cylinders. even supra guy swap out the factory TT in favor of a larger single turbo, you can get way more power out of it.

^ that and single turbo setups are easier to work on.

the smaller turbo on an FD RX7 is one of the weak links..that turbo goes out frequently and is a PITA to even get to. I think you have to drop the motor just to get to it

not all true. twin turbo can serve a purpose on small displacement 4 bangers. turbo lag is a huge problem most 4 bangers suffer from big turbos. having a smaller turbo that spools up incredibly easy will obviously help with turbo lag on the big one. yes it's a little ridiculous and isn't seen often at all.

iceman: you need to do a lot more research on turbos dude. possibly read this: http://search.barnesandnoble.com/Max.../9780837601601 your questions scream noob sorry.

If you don't want it to be a drag car and rather something that you'll just drive to the track on weekends, I wouldn't suggest getting a huge turbo. True that you'll probably hit a better power range easier but you'll probably be slower around a track because of the increased turbo lag. The power will be basically unusable in a typical condition, like in a city. I really wouldn't think anything over 350whp would be driveable as a DD in a city because it IS FWD... You can reach 350 with the kits that are selling right now, Turbo Toyotas, Dezod, etc.

Most of the kit i'm seeing is 270-300. If I want more HP then I have to go with a larger turbo than the ones they are selling?

wouldnt the turbo system youre thinkin of be a sequential turbo set up? where the smaller turbo is in direct line with the bigger turbo so that it spools the bigger one up faster? where as in a twin turbo set up there are 2 spooling to create power together.

from the sound of it looked like he was trying to go for one turbo for 2 cylinders
