i think he meant a t3 by itself is too small

Rotaries produce too much exhaust energy for t3's. T3's work well on boingers. The "35" on the gt35/40 is the turbine side and has a t3 style flange. It is not a plain T3 style turbo though.

 

60-1 is made by turbonetics. Same guys who make the T-66

 

Ok, Thanks! I thought T66 and 60-x series turbos were Garrett only

 

I think lag and boost response are being confused here. If you're looking for a ROAD RACE setup, and not an AUTOCROSS setup, then you only really need a turbo with good boost response. (i.e. in the upper rev ranges, the car builds boost quickly). For an autocross setup, you'll be letting the revs drop a lot lower through the corners, so you'll want a turbo with minimum lag, that builds boost quickly from very slow speeds.



That said, for autocross, I think the RX-6 would be a great turbo. Though it lacks the top end of some of the others, from what I've heard, it builds boost incredibly quickly.



For a road race setup, just keep the compressor sized so it stays in its higher efficiency ranges, and the hot side A/R within reason. BB turbos always help in response, just make sure you get a good one. I've heard that turbonetics' single ball bearing center section turbos tend to fail, but the dual BB ones are more reliable...



good luck!

the rx6 is ball bearing if you were wondering. mine has good power down low and pretty nice pickup in the higher rpms as well. i make full boost "13psi" at about 3000rpms. by no means is it a drag turbo. but it is alot better then the twins.

 

Boost Response determines the speed from where to where? (rpm range/turbo speed range/boost level)

Thanks! Does HKS, etc make their own turbos or do they buy from manufacturers?

 

HKS turbo's are basically turbonetics turbo's with a convex bottom on the compressor wheel and a concave back plate(or it may be the other way around). They are identical in every way except for that. Basically, if you **** up an HKS turbo(compressor side), you'll have to replace it with HKS parts....which tend to be more expensive than turbonetics parts.

 

hks = garret

greddy = mitsubishi

apexi = ihi

turbonetics= turbonetics

Ive heard of a Apexi RX6b what is that?
