well guys i was just wondering whether the To4B is more power efficient for our cars rather than the other type which is a To4E....the only difference is the compressor wheel....i just want to know how the results have turned out for you guys that have put various types of T4 series turbos in our FD's well thanks and peace out

Did you know that the 60-1 and 62-1 are TO4B's? My vote goes for the TO4B. Actually there are so many variations of the two that you can't really make a blanket statement about which is better. **** you could have the smallest example of either and make far less power than a stock T2 turbo.

The 'E' series compressor wheels and compressor housings are more efficent especialy in the 15psi plus range. The 'E' wheels are 6-blade vs 7-blade for the 'B'.
The 60 and 62-1 are considered To4-b's but are in a class by them selves. There is a 63-1 turbo that have a 63mm/6-blade compressor wheel.
