Diff between "big28 and a s15 turbo...

[s14det]

What are the differences between the 2 Hopefully I am going to be getting my s13 blk top with a s15 turbo shortly and was wondering would it be better to do a big 28 instead?

Thanks,

Big28 is a hybrid between a T3 and T28/25 and the S15 T28 is just a ball bearing T28(i think?)

hmm, try searching, you mite find something there, i personally dont know, but i havent heard of the Big28 from the factory, if its aftermarket, it is probably a hybrid between the t3 and t28 like mentioned before, however i cant' imagine that itd give u more htan about 25hp or so, but im not sure

S15 will do up to 300 about but i have heard the Big28 will put out 50 more hp.

I dunno about the big28 but the s15 turbo is dual ball bearing, all i have to do is blow on the compressor wheel and is spins soo easily.

J-Spec is right on the power output.

I don't thing the Big28 is a ball bearing turbo.

Cool, thanks about the info. So they both have there good and bad about them. big 28 has about 50 HP or so, and the s15 is proberly a faster spooler..
