I have a question, all though it is not time yet, i am preparing for the dreaded day. I have an 85 rx7 gslse and i was just wondering...the day my engine goes, it has like over 250k on it, should i put in a third gen engine, i have a friend that would do it for free, yes lucky me. Or should i buy a 95 whateva the best model, by the way what is the best model of the third gens?...I was just wondering. Also would it be a very signifigant power gain? i know its a dumb q, but i was lookn for ball park figures. And isnt a single turbo better than two because the two just couldnt pick up the lag or something like that? I heard a few peeps that have supras and some 3rx7 and switched to 1 turbo. Thanks for any help!

 

1 big turbo will allow better topend power, but a bigger turbo takes a bit longer to spin up. they came with sequential twins so the smaller turbo would spool at lower revs and the bigger turbo would take over when the smaller one reached it's capacity.

a lot of people do the single-turbo conversion for the dyno queen factor, plus 1 turbo is less complex than a pair.

it looks like the best bet for a turbo 1st gen would be to install a 2nd gen turbo2 motor. they come cheaper and you can get the same kind of power from them as you can a 3rd gen motor.

 

Yeah, 2nd gen stuff is just plain easier to deal with.

I know a guy with an unfisnished '93 engine conversion in his GSL-SE that will get a supercharger. He wishes the engine's front cover had a hole for a dizzy or CAS because he dosn't want to deal with the crank trigger stuff (he's real old school).
