Well it's getting pretty close to my annual new engine rebuild in jan/feb which should last me untill march/april. I can either work with what I have. Ditch it all and go HKS v-mount & HKS T04Z which would actually be chepar then fixing what I have and maybe more reliable or go with the dream project. What's another $15k down the drain when i've spent over $75k allready? Anyone wanna buy my car with no engine for $30k? I've put more miles on my motorcycle in 7 months then I have with my RX-7 in 7 years.

Anyhow, it would be dual Tial GT25's or something close to that. Isn't that what M2 used or was it GT28's?

So, just trying to get some input on expense and time spent. Engine bay pics would be great. Do's/don't or advice, etc.

If I had your luck, I think I would go with something tried and true.

Here is a link to a semi-Local guy that is doing a true dual turbo setup

This is completely off topic, but how have you spent $75k already? My white FD project car I've budgeted $25k for the stuff that I want to do to it. (that doesnt include the cost of the car) And it will be "done" in my book after all of that has happened.

looks like its not his first time.

howard should ring in.

thank you, that's exactly the reading I was looking for.


I paid $25k for the car so at least $50k in engines, turbos, more engines, several different suspensions and exhaust and etc. I wish mine was done for $25k.

RX72NR's project is very nice. His car will look tight. My ideas are similar but not hte same. If I were to do lambo doors i'd copy the brackets in titanium. W7 is too much weight I have dual W3's. Anyhow my original plans were for internal gates and dual exhaust. No one has done a true dual exhaust, so maybe I would still get to be the first. I would use alot simpler fuel system. Ever since I first saw Border Racing's dual single kit I wanted it. I think my idea is alot more efficent though.

sounds like you need to move the firewall and go ITB N/A 20B...and not worry about complex fuel systems, fitting twin turbo's, $$ V-mounts, custom motors, etc etc.

With to said engine you will be racing every season all season for a long long time

/\ true with all the money spent you might as well dump a 20b in there and leave it, that way you wont have to worry about the power since youll have globs of it!

ITB 20B ~ 300whp tops no?

While a dual single is pushing 500whp no? Different game.

no.

Check out GTORX7s results.

Yep, lots more seat time and the bleeding stops

Hmm you guys are making this sound interesting.

I can buy a 3 rotor and the kit from Defined, with streetporting it will make 350rwhp in N/A form which is like a 13brew @ 14psi???

i think a 20b is over pricing, with the manpower you can just buy the $4000 dollar motor with the right transmission and just swap it in there and make sure you have the right wiring, and just mod it as you get more money. the amount they make out of these 20b's is the reason why were getting our asses handed to 1000hp supras

Did he ever actually dyno and get those numbers? I think that was a butt dyno estimate of 350, probably close though.

20b NA would be sweet for AutoX. Response, low end torque, reliable.

Yeah if there is ever an '09 RX-7 with a 3-rotor I will ditch my setup and buy it from Mazdacomp. I love the smooth RX-8 just not enough power. I want my car to feel more like my CBR 1000RR. So a 3-rotor with 15k redline would be fine! :
