a t3/t4 is a hybrid turbo. it uses a t3 exaust side, and a t4 (bigger) for the compressor. The reason is the fast spooling of the t3 and the big airflow of the t4.

I've got a t3/to4e sitting right here on my desk. The to4 series compressors will get you alot more hp than the t3 compressor, but at the cost of more lag.

?
So does the t3/t04b lag more or spool faster?

The t3/to4b setup will (generally) be less laggy than a full t4 or a t3/to4e setup but more than a full t3. It would also be good to know the wheel trim and housing A/R. You have to trade power potential for lag in most cases. This is really to big a subject to explain fully here. Do a search on turbo selection or better yet do the same search over on the rx7 or supra boards. I've got an article from Hot4s magazine from Australia that actually explains most of this for Subaru upgrades, but no scanner. Turbo magazine has had a really good article on picking a turbo for the past two months (first two in a series) that is really good at explaining it as well, right down to using compressor maps. Damn I need a scanner!!
