Slowtegra Posted April 13, 2004 Share Posted April 13, 2004 Hi, I'm a new user, this might be a dumb question, but im going to ask anyways because i dont want to buy a turbo that is too big. Would a t70 turbo be too large for an sirII motor? I'm eventually planning on builing the motor so it can handle heavy boost, so i dont want a tiny turbo that ill have to replace when i build the engine up, but i also dont want a turbo that in the meantime doesnt make boost until like 5000 rpms. can somebody help me out?

..SSR.. Posted April 13, 2004 Share Posted April 13, 2004 WAY too big. Link to comment Share on other sites More sharing options...
Slowtegra Posted April 14, 2004 Author Share Posted April 14, 2004 I thought that it probably was too big, it seems more like a turbo for a single turbo supra, but there are a bunch of t70's on ebay and the person selling them lists them as for civics. so that sparked my curisosity. thanks for letting me know. this is a link to one of the auctions if anyone cares to see Link to comment Share on other sites More sharing options...
Slowtegra Posted April 15, 2004 Author Share Posted April 15, 2004 which would be better, a t3/4 turbo with an exhaust ar of .48 or .63, assuming every other aspect of the turbo is the same besides this by better i mean which will spool up quicker and which is capable of more horsepower. im pretty sure i already know the answer but would rather here other peoples opinions. Thanks, Dylan Link to comment Share on other sites More sharing options...
S14Silvia Posted April 21, 2004 Share Posted April 21, 2004 my opinion is that t3/t4's are old technology and that you'd be better off getting a garrett gt28 or gt30 although the gt30 might be too big. gt28 will have great spool up and is capable of 300whp pretty easily. t3/t4's will get you more power, but the spool up wont be as good as the dual ballbearing gt28. however, in response to you're question, i believe the .48 will spool faster, .63 will give more top end.
