massive turbo upgrade

[ALLeyesONmyGSX]

well guys... i have come to a dilemma... whether to choose between an Turbonetics RS49T ( http://www.agpturbo.com/customer/product.php?productid=113&cat=72&page=1 ) or a RS60T ( http://www.agpturbo.com/customer/product.php?productid=114&cat=72&page=1 ) ... price wise - they are the same... as far as im concerned, its a matter of how much $$$ i want to spend on supporting mods... mods are listed in profile, i would definantly need a larger fuel pump (TT supra?) and possibly larger injectors... i have denso 660s now... and a couple of questions wouldnt hurt either--- so--- to my understanding these turbos bolt up to the stock manifold and o2 housing... with an external wastegate, i would no longer need the o2 dump--- would a stock ported o2 housing work well w/ an external wastegate ? ... my current clutch is a street disc, would that clutch hold up, or would i be forced to invest in an ACT 2600/3200 ? <--- since a 6 puck may be needed... would i be driving in a fear of crankwalk... ? would i be forced to invest in a 6 bolt ?... thanks ur time n help guyz...

I just bought the RS 49 and i think that that is plenty of turbo.
I had a guy just PM me and said he is running a 60-1 right now and says it is just not responsive enough at times and hates the lag. He is trading down to the 50 trim

You say you have 660s now I think you'll be OK on theses. I'm running 680s with mine.
i see alto of guys on 660s with 50 trims with out problems.

I'm running an Evo 3 02 housing with mine, its ported heavily. Should be good to go.
