rb20 or rb25?

[clovers525e]

well, i'm sort of new to the world of 240's. i've been playing with mine a little and have already grown tired of the whole fugly n/a ka world. i've had my heart set on an rb for a while now, since i saw my friends s13 with a rb20 swap. i've herd alot of flack on the smaller then ka platforms though. from what i understand the crank bearings go out and the trany's arent to grand. but the price of the 25's is outragious. i'm looking for 300 to 350 reliable horse power which is why i fell out of the rx7 world. i guess the question is, how much can the 20 handle on stock internals (will be replaced for 20 over pistons after a little while), how much can the factory turbos push out and what would be needed for my goals.i'm looking to keep up with my brothers 13b-re powered fc (t66, e6k, apexi gt 4inch exhaust, 1600cc injectors, fd fifth gear syncro) oh ya, and 200mph?

Hi welcome to NICO...on here you're gonna find the answers to most of your questions by using the search button before you post a question that may have been answered already.

Check the RB forum for more info.

And BTW there is nothing wrong with the KA24DE...while looked down upon...a turbo on a KA with some engine can produce quite some results.
