Yo Good Find! I want that car...thats the new dream car right there. If they actually bring that out as the next rx-7 im selling everything my house if I have to to get that car.

 

That as the next Rx-7 ahahah never. Just the tub is like 250,000$.

I think it just goes to show that there will be another Rotary car competing at La Sarthe in the future.

The taiki is what I think is gonna be the next Rx-7 and I think that will be the sexiest car of all time just look @ that bumper.!

 

G'day, if the car is going to be used as a street car here's what I'd suggest having both an na & turbo 20B.

My 20B is in a lightweight first gen RX-7, with an extend port and the stock 20BT rotors it made 245 rwhp. This was pretty fun to drive on the street. especially with the 4.4 gears I had in it, you could quite easily take off in 3rd gear if you wanted and it still had plenty of top end speed. Drivability was very good, you can boot it out of corners and it was always predicatable. I'd estimate it probably would have run a low 12 over the 1/4.

Then I bought the itb's off Gto. This gave an increase of 50 rwhp. You could feel a massive difference throughout the rev range, Gto really did a great job with these itbs. Although it was more difficult to get off the line, it was great once it got going, especially 3rd & 4th gears. It made 295 rwhp with this setup and was a good safe street setup. It prob would have run around a mid 11 over the 1/4.

Then I went turbo, a TA45 style turbo. On only 6 lbs it made 404 rwhp, but it was no more as drivable as the na setup, you have to be careful where you let it go, no more full throttle out of corners thats for sure. But the rush once it comes on boost is hard to describe.. I am glad I did it this way, as I was getting used to the power of it being na. With this much power in a lightweight car on the street, you don't want much more. Your second gen will be a few hundred kilos heavier, if you were to go na I wouldn't worry about changing rotors to high comp ones etc as you will most likely want to go turbo one day. I have only run mine up to 9 lbs where it made 450 rwhp wheel spinning on the dyno (larger rear wheels in next on the shopping list) at this low boost this turbo really isn't even working yet so there is heaps of potential, I'm still only running the same exhaust I used when it was na too, 2.5".

Anyway.. hope this helps, I know what you are going through as I spent a lot of time deciding which way to go. If it was me, in a heavier car like a second gen, I would probably go turbo straight up, run it on low boost and go from there.

 

Well, bought a 20b today from Japan2LA. Yea, that's right. I am the one that said no mas, no mas one month ago. It is a C code with a blow apex seal.

I am really torn. My thoughts are to go with the n/a because that will stay with the GTUs philosophy. I mean if I can get 350rwhp and add a 100 or even 50 shot of nitrous....****. Best of both worlds. I am not sure about the nitrous. Not worried about the engine just the added complication. Simplicity and reliability are keys to this project.

I am wanting to make the car kind of like a factory Mazdaspeed hotrod. The 20B FC they never made. No bodykits here.

When GtoRx7 gets his car going I am going to fly up to Ohio and get a ride or hopefully get to drive the FD 20B N/A. Empirical evidence will help with this decision. Not sitting on my *** reading comments on a forum........

I really think that some day I am going to end up with a FD V8 also. So this doesn't have to be the end. The ***** to the wall can come later.

I will tell you one thing, I will not deal with a ridiculously loud car...period. That actually could be the deciding factor.

I also am a bit afraid that if I do a turbo then I will just want to turn it up and up and up and BOOM. With the n/a I build it, drive it, and enjoy it for what it is. I guess I am middle age now and all out is not so important anymore............maybe. Anyway, thanks for the input guys....... The affliction is in full force

 

Who owns Gto throttle body set up now? Any pics of it?
