I have a street car that has a 404 ls2 in it. It will soon have some ported l92s, a fast 102, and a pretty big cam.

What kind of tb should I go with?

Id like to keep the setup as cheap as possible but I dont want to skimp if its not worth it.

I am not sure of the performance difference between the 102 and 90mm tbs.

BTW I currently have an slp 85 mm maf and an mti clear lid.

if you do end up going 102mm t/b id recommend getting the fast t/b and not a nick williams or any other 102. the reason being is that the fast 102 t/b has a small raised portion at the bottom of the t/b to help with part throttle and idle. so in sence the t/b only opens at the top and not at the bottom untill you are past the raised portion at the bottom of the t/b. i have a fast 102mm t/b on my 416. it was easier tuning my 416 with the 102/102 then it was tuning my stock cube ls1 with a fast 90/90. id like to think part of the reason is the raised area. i included a picture so u know what im talking about.
