Twin turbo or single turbo?

[jae_k]

which one will give off more hp and torque?

[poormansporsche]

I'm no turbo guy, but I can tell this is not enough info. Your going to have to be more specific for an accurate comment in response.

[jae_k]

Hmm.. I don't know how specific I can get with this question. What company for turbo and what company for twin turbo? After that has been decided which one will give off the most hp and torque? Hope this narrows things down a bit just started looking into turbos so I'm not the turbo kind of guy neither, that's why I need the people who knows about turbos to help me out on this

It's my undersatnding that you can install one BIG ASS turbo and, properly tuned, it will kick ass on small twins. As with many things...size matters.

Whichever setup will force more air into the engine. It will all matter on the sizing of the turbo(s), and how much lag you are willing to live with. More is always better*

*not always

In general the larger turbos are more efficient at compressing and moving large volumes of air.......so generally speaking one large turbo can get you the power cheaper (easier piping).

However smaller twins can spool up quicker giving you a more responsive bottom end.


To the OP, IMHO you need to start with a budget and power/performance goals before you start shopping (daily triver, road course car, 1/4 mile car, etc.). If you are looking for big power, then most guys suggest you build your engine. I would look for a good reputable tuner before buying and get their input on what can be done and how much it will cost to set up your car the way you want it.

Any recommendations on which turbo kit I should get? I hear good things about greddy twin turbo kit.

^^^^ Very nicely said GZ !

Some pretty cool stuff in the singles that Porche uses with variable vanes.

Does your car have an automatic transmission?

GReddy is OK, but it's more ala carte than say a Jim Wolf kit or APS kits. I would say also that the JWT & APS kits have better overall materials.

Again, you should really set a budget because your build can start off around $6,500 or so and easily go up to $25,000 to $30,000.

Single turbo has more power potential, if the turbo is big enough...

[jae_k]

I hear turbo's are high maintenance parts. You also have to upgrade the engine to prep it for the turbo too right or else it'll over heat or start smokes?

When I say that I mean no offense by this, I truly mean it and hope you won't be offended...so....here goes...

IMHO, I REALLY think you nedd to do a LOT more homework on this one before you jump into it. I believe it will be in your best interest to read some books, magazines, search old postings, etc. before you ask which turbo to get, etc.
