Now a 240hp n/a 13b, its been done, and I've seen them last years. I would rather keep the RX a RX. If u cant appreciate the rotary u dont deserve a 7.

LOL deserve a 7? The question is does the rx-7 deserve a motor like the LS1?

Listen there is no pint in argueing over this. It will never be solved, especially not online. Its like comparing an apple with an orange. Its just not going to end, so give up, lol.

68 Vette you got no chance mate!

The power of the rotary engine is absolutley awesome and you dont have to spend much money to run some quick times were as a v8 you would spend maybe double even sometimes tripple to make a v8 go as quick as a rotary.

68 vette give up

a buddy of mine witha 94 touring FD with walked all over a ls1 camaro with 4.10's and some other stuff...... so i choose the rotary. He also beat up on a modded c5 vette.

omg dude the over sized miata beat the big bad v8

Sorry this was very long time ago, but I could tell you the setup. It was one small turbo only capable of ~8psi (good for low end torque), and another bigger one good for 30psi. If you are a v8 guy (which u kinda seem like) you know of exhaust cut-outs right? well there are PSI activated exhaust cut outs that were used on this twin setup. I'm not sure how it was setup, but I have a pretty good idea: 1 cut out for each turbo, the smaller turbo's cut out remained open until 8 psi, the larger one was closed, then at 8 psi it is reversed. The torque was as low as 2k I believe. But like i said before it really depends on which turbo(s) you have. Some guys are even experimenting with VATN turbos (variable turbine exhaust A/R). There are "vanes" on the exhaust side of the turbo which can vary the turbo's A/R. 14psi can be had as low as 2k. Also some specially matched T3 turbos seem to be very promising, there is a dyno sheet of 300hp/300lbft of torque at 8psi.
Dont get me wrong I like the torque V8's put out, and just overall power, but in a nice classic muscle car. And please dont assume just because its rotary it has no torque (which a lot of ppl do), it just really depends on what you put into it, and what you want to use it for.

Can you pls not call it an over sized miata. no offense to neone here on this forum, but miatas are usually associated with gay ppl, and/or ***** cars. The RX-7 is neither.

God soo many people act like they created the car

Lol lets get some extremly rare and cutting edge variable exhaust turbos with electric psi exhaust cutouts in order to make 300lbs of torque? LS1 is doing that NA right out of the box. Basically no one is saying a rotary is totally worthless, we are saying the LS1 is stock by far the superior engine.
Heaven help you if you put a turbo on a built LS1, it really is way more power then you could probably make use of on the street.

Or hell just put a stock LS2 motor in the 7, thats 400hp stock NA right out of the box. IMO I would rather have a big block chevy that is NA and redlines at about 6500 and is capable of making over a 1000HP, then a forced induction or nitrous motor, there is more going on with those cars. I like to know that the car im driving is barley even trying to make torque and yet it still does and is not screaming in the RPMs to have to do it. High RPM power can be alot of fun but take a ride in the average built big block, 454 crate GM motors are like 500lbs of torque.

Why should i give up, it is stupid to argue. Both sides pose good arguments, but there is never going to be a clear cut winner. As i have said many of times before Rotaries are amazing, but they just have not had the technology, and the money spent to research, and produce them as the pistons have. Also what dont i have a chance at? It is only a matter of time before this thread is closed, just like the others that desputed this...

I am actually debating on this at the time. I have an fc and dont know if to go for a t2 conversion or an ls1. me and my brother are very short on cash though and the ls1 seems a little too expensive of a swap for us.

Haha well said , nothing like the hyperspace ride in BBC.

[crazyboosta]

This thread has turned to shit......................no offense but its obviously a mainly american thing to do(Just like the E-Type Jag with a V8 swap Ive seen before ) Swaps like that are not very common in Australia or NZ, Maybe it is cheaper for you Americans to do that but i still cant see the point. I know Rotaries have there flaws but its just not right to put one in an RX7.

Lock this now
