Go with the T-78, not to bad as far as lag, but anytime you want big HP your going to have to have a big turbo, so there is always going to be some lag, 500 is alot of HP, but you could get it with the T-78. good luck

The statements "not too much lag" and "500 hp" are pretty much mutually exclusive.
It's all about your preference and driving style. There are people out there running a T88 (++++++++) and T51 (rotaryextreme) on the street. I personally do not think those are very "streetable" turbos. They make damn nice 500+ numbers...but the obvious sacrifice is low end power.
Other turbos like the RX6 and TD06 spool very quickly, make decent power, blah blah...just nowhere near 500 whp.
But I have an even better idea. Just throw a 20B with a Y2K and you will have low end torque and a lil bit of top end too!!

Seriously though, the T-78 is pretty good on the lag side for a turbo capable of 500+ RWHP. Just make sure that you're in the right gear.

I'm pretty sure in a few decades, biogenetic scientists are capable of creating a tree that sprouts leaves that look similar to some certain dollar bills.
Heck, the U.S. Mint might use it for legal tender since it costs too much $$$ to invest in conterfeit measures in our current bills. With the money tree, each bill will have it's own genetic signature! Talk about the ultimate in conterfeit proof.

NYC's Loudest FD
I had a T88 setup with a Power FC and it boosted pretty quick for such a big turbo, the car was daily driven and was completely streetable, I wouldn't consider it really big lag time, I know some guys with smaller single turbo setups that had more lag than I did, the Greddy turbos are known for spooling pretty quick because of the design of the turbine housing. Plus tuning has alot to do with lag, because if your A/F ratio and timing aren't proper you will get considerably more lag, just my 2cents. BTW I bought another T88 kit for my other RX7 cause I liked it so much.

Lag
Gentelmen, i hope you are all aware that lag can be somewhat controled with the exhaust manifold design...if you catz know about some thermodynamics and fluid mechanics you will see how it could be possible to reduce lag a bit. I am starting to do some more research so i can build my manifold.:p or.....maybe i'm talking crap let me know what you guys think.

Exactly what i mean when i say the manifold design , there should be some certian lenghts to tune with the A/R even materials used would help reduce lag trying to keep temps as high as possible until they get to the turbo...ceramic coating is good for that. Greddy makes some nice turbos when you get to the GT 30 and such due to the bearings doesn't take that much energy to get that puppy spinning. Just remember in the energy equation KE=1/2m(v*v). the faster you can get those velocity gasses pumping the faster you'll be boosting.

T61?
ive heard some good things about the T61, or maybe even the level 6 frank series?!?! And a question too...im new to the rx7 and new to researching it, where could I get an upgraded ECU? or FCD? if i moderatly mod my car(~350+hp) would a standalone ECU with a FCD work or no?
