I'm new here. I guess my first question has to be: is there any way to convert a '95 Eclipse Turbo to a Twin turbo? I'm from Utah so you can imagine that my car knowledge is limited. There aren't any tuning shops, well, any shops around here to get advice or anything from. I'm just looking for some fb on this subject. ie: would it even be worth it to convert to a twin turbo or stick with the stock motor and upgrade that? Any suggestions would be awesome.

 

You can but it would take alot of fabricating and is not at all worth it. What is your goal power wise, because the stock 4g63 motor can handle 400 whp.

 

its possible with two small turbos. dont uhave enough cylinders to push anything bigger than maybetwo stock turbosin my opinion. but it wont be efficient. you can get around 350 easily with a evo3 16g. or if you crave more power you can get a 20g and get you around 400hp or so.

BUT if you have a FWD, like i do, when you get to 300HP, you lose alot of traction and might want to think about putting in a LSD to help with it.

i just had a discussion with a guy at work about this. he wanted to put a "Biggie-Smalls" (big turbo with a small turbo) on his Spyder GS and i had to tell him that it wont work unless you have at least 6 cylinders. but hes a idiot anyway....lol

 

there'sa vid of a guy who convered it to twin turbo a long time ago racing a Camero SS and got raped. just because there are 2 turbos doesn't mean that you will have twice the power. that's why most people looking to push a lot of power out of their skylines, 240's, supra's, Lexus IS's, etc etc etc usually convert to just1 large turbo.

what is your end horsepower goal?

 

Like they are saying you do not want two turbos. The system, piping and setup are just way to inefficient and its not worth it at all. With more research and learning youll realize that one single larger turbo is better than two. And on a 4 cylinder car, single is definetly the only way to do it. But i suggest you start looking around the forums and doing research before you even think of doing any turbo upgrades. Start off small

 

if you aren't very familar w/ turbo's here are 2 AWESOME sites to look at.

HowStuffWorks.com - (http://auto.howstuffworks.com/turbo.htm)

TurbobyGarret.com - (http://www.turbobygarrett.com/turbob...ch_center.html)

this will teach you everything that you want to know.

 

you stole that from my write-up, haha. JK They really are great site. I like the Garrett one cuz they show you how to read compressor maps and get really detailed

 

you have those in a write up? well i just happen to find howstuffworks.com one day like 2 years ago when i was trying to find some info on turbo's and have been recomending it ever since. but the garret site i just found out about last week and Turbo's 102 has AWESOME information when it comes to trims/AR's/sizes etc etc.
but EFF Turbo's 103 lol i didn't even bother looking into it once i saw the graphs lol.

 

nah you gotta read the 103 with the comressor map info

 

wow those sites are really helpful. i didnt know that much bout turbos myself lol
