hks to4r rx7 vs greaddy t78 rx7

which would you rather have and why?im looking at both kits (leaning more for the hks) the diff. in price, including intercooler is about 20 bucks between the two. the only thing the hks kit has that the t78 doesnt is inter cooler piping. so which would you pick and why?

Out of those 2 I'd take the T04R. I think personally if I was buying a kit I'd take the GT35/40. That is if I had an FD and not a TII

I love my t78 rx7 if its any help. The lag isn't as bad as people make it out to be. I believe you can make more power out of the t78 according to what a lot of people say.

Where are looking at turbo kits? Everywhere I check has the the T78 as being much cheaper.

I don't have my T78 back yet but Skip at KDR and Jason from RX-7 Store both told me to expect peak boost a little after 4000rpm. Skip said its only a little worse than the twins running non-seq.

with the intercooler its about the same because i found a site with the hks a little cheaper then the greaddy which was kind of a shock because hks stuff is expensive!

what kind of ports are you running?

Their quotes were with a large street port. I decided on a half bridge so my lag will be even less. But I think 4000-4300rpm for full boost is pretty good for the power you get.
