This question probobly gets old, but I woul like to know what would be better on an FD. Would it be better to upgrade the stock twin turbos or go with a single turbo.

 

hi,had my turbos of the other day and there where cracks which is a common prob,did sum phoning around and it seems to me that its better to get just the one turbo instead of two, there spose to be more reliable and problems are easier to find plus it frees up a load of space in the bay,which i guess would help with cooling a bit. plus you can go bigger bhp with a single. when it comes to it i`d go single.

 

There is no "better", it's what qualities are important to you.

Single vs twins:

Pros:
*Typically more power potential.
*Simplicity in engine bay and boost control setup (can be nearly duplicated with non-sequential twins).
*Typically result in slightly lower air and coolant temps.

Cons:
*Going single properly costs several thousands of dollars.
*You lose ability to pass emissions with most of the kits, and all kits for states with visual testing (like Cali).
*You lose low-end power and have increased spool, some of the larger turbos have significantly less low-end = don't have same power as stock twins at 3k rpm until 4k rpm or later.

 

Nice synopsis Tyler!

 

I would go single. Prob. an Apex-i RX-6. With the manifold that mounts the turbo back so you can still use the airpump. I have read that they spool up fast. Then again, my twins have never worked correctly. (Didn't check boost pattern when I bought the car.)

I did my single just for the simplicity and power, I am just lucky that I moved to Juneau and dont have to worry about smog, even then if I stayed in Nor-cal, I stll would have done it anyway since I hate the rats nest.
