Ok i know this is pure fantasy for me but i want to know some of your opinions on what would be a good single turbo on a 20B. I know Greg thinks a Turbonetics T-100 or Y2K would be good. I'm sure that would make over 700 hp but i wanna know how streetable that turbo could be. I wanna know what turbo could be driven around town but not run out of gas on the top end. This car would need to have enough HP to run in the high to mid 9's. Again I know this is pure fantasy im just curious.

 

I'm not too knowledgeable or experienced with 20B's but...

I would think if going single you would want a pretty damn huge turbo. The 20B makes plenty of HP and Torque w/o any turbo, especially down low compared to a 13B, that you wouldn't have to worry as much about low rpm power of the turbo. Get a very big one, and when cruising around and stuff, it won't be spooled up yet so it should be streetable with big mileage. Drop the hammer and your car should rip.

I'm not sure of what turbo's would suit best, but that would be my general views on it w/o too much knowledge of 20B turbos.

 

If you are going for streetable horsepower I would seroiusly stay with the stock twins on a 20b and most people usually get about 550hp, at least that is what pettit and pfs gets out of them. Will it run nines?? probably not. But you will still kill alot of things on the road with that wide of a power band and a light car. But if you want a full out drag car I would go with a huge turbo like greg was talking about. I'm not sure how something like a t-66, t-78, t-88 would work, I imagine not too bad, but most people say you will suffocate the motor..

 

Yeah I've heard all 3 of those would choke a 20B on the top end.

 

you could run twin t-62s

 

I've been thinking that bigger twins may be the answer.

 

what are the biggest twins a 13B FD can have in it?
Also can you pair a fast spooling turbo before a larger laggier turbo in a sequential system to get the highend power without the lag?

 

I would go with a really big turbo because you gotta look at it this way, if a 13b can spool a big single turbo pretty easy, then think of the response and HP that you'll get out of a big turbo in a 3 rotor which has 50% more exhaust pulses than a 13b to spool a turbo.

 

Gotcha...twin TY2K's! Hell Yea!
