I priced out the work I would have to do to the 13b to make it as reliable as I require and it was around 12k. I can build my sr engine for 4k. But, i need another 2k to build up a s15 tranny, and a saftey net of 3k just because shtuff happens. 9k with 3k of safety or 12k +/- who knows. I'm not about tradition. I'm about making something my own. a lot of people get angry with me about some of the things I've done. I'm sure if I do actually put a 4banger into a 7 I'll get a lot of negative comments. But I think the two will match up well on a tight technical infield. nothing wrong with revving to 11,2.

The handling of a 7 is what has kept me drawn to it. a simple tien SS EDFC, poly bushings, and the different linkages and stb's make the car AMAZING! It pisses me off when my race car gets over-taken in a turn. really pisses me off.

edit: spellcheck and forgot to mention suspension.
9k with 3k of safety vs. 12k +/- who knows. You're right about this one, but have you thought about all of the custom fabrication that you're going to have to do, let alone adapt the FD harness to the SR sensors, and then figure out a way to let the computer make sense of them. The swap will run you between 15 and 20k after all is said and done. Your 9k estimate for the motor, is that just motor, or is that with computer and tuning and everything?

I'm not trying to **** on your cornflakes, but there is more to the swap than just building a monster of a N/A 4 banger. Good luck. Keep us updated.

To the thread maker: Just go with an LS1. A stock LS1 will give u 300rwhp give or take, and not affect the handling at all, if you do the conversion right. Plus you'll get great realiability, 30+ mpg on the freeway, and a very smooth powerband.

While Im not a huge fan of small displacement N/A engines, it sounds like an interesting idea.

To all the people saying the FD chassis weighs too much...look at LUPE's car. Id think if you made it a race car, you could knock the weight down to ~2300-2400lbs, and 250hp would move it quite nicely.

Its called constructive critizism buddy.

The car already comes with everything it needs to whoop ***. If reliabilities your problem, 1. dont go cheap on stuff, 2. dont half-*** stuff, 3. Get a reputable builder/tuner, and 4. Dont treat the car like ****.

Its nice knowing the cars known for being unreliable. Keeps retards from buying the car cause theyre scared of the problems. Once the idea of swapping pistons into the car gets out to everyone in the public, it gives those retards a green light to buy this "purdy car" and drop a piston engine in it to make it reliable.

All i know is that one day when the time comes, god forbid, if my FD gets really messed up, when i go to buy another one i dont want to look through one page on autotrader and have 3/4s of the FDs already have v8s in them.

If you really like the car, then like it for what it is, and deal with it. It makes me feel like a real billy badass driving it with the bad reputation is has, yet i must be one crazy mother ****** to do so.

Ya ls1 whatever whatever, but 4banger N/A gimme a ****** break. go get an s2000

It's his car to do with what he wants. And the Japanese have been doing crazy things to their cars since long before you and I heard about RX7s'. Go on cardomain.com sometime and see how many RX7s' with body kits, neon lights, huge wings out the back, and half the interior ripped out. I'd rather have a V8 or 4cyl powered FD with the rest of it intact, than a rotary powered FD, with half of the car's characteristics ripped out. Engines can be swapped back in. Bodies are hard to get back to original.

Also, what's wrong with wanting to take a great car, and make it better? Everyone has their own opinion of how to make the FD better. His is 4cyls, mine is lightweight V8's, and yours is keeping it rotary. We all have a different approach with how we look at our cars and want to improve them, but the end outcome is the same, is it not?

To the thread creator:

Why not look into an N/A 13B? They are crazy fast once you start dipping into the bridgeport/peripheral port ends, not to mention they've got the the unique smoothness and responsiveness that you can only get from a rotary. Hell, an N/A 13b buildup should even be cheaper than an all out SR20 buildup. While you're at it, why not look at the FC chassis as well?

My real question is why you're so adamant on the SR20 platform. I mean, sure, it's a good motor, but is it really so good that you have to swap it into every other car that you decide to buy?

I'm with this guy on the subject. I've built N/a 13b's with 190-200rwhp on shoe string budgets for ***** and giggles in daily drivers. I bet 2k would build the motor, and nearly have standalone too. But if your going to spend 12K, do what I did, build a n/a 3-rotor and have 350rwhp/ 2600lbs. Stock trans and all.

I have many of the parts already, and the expirience of working with them myself. It's an obsession I need to kill, but the 86 is going to be full track sometime mid summer probably. full guts and re-builds are a lot of work. sounds like most of you know where I'm coming from. I might buy a 95 r2 from a friend who's done a 99spec conversion. even the motor is a 99jdm with the twin high-outputs. Dunno what I'd do to the car other than some suspension mods. that's if I buy it.

edit:

I just realized this thread was re-opend or moved or whatever. I started a second one because this was closed. I ended up buying an AE86 with blown motor/tranny and I'm dropping the SR into that. Since I already have most of what I need for that swap it's pretty cheap, leaving me room to buy an RX7, like the one I talked about earlier in this post.

you beat me to it!

3 rotors are very capable of revving to 12k if you really want to. Way more power than a 4 cylinder, way more torque, MUCH better sound, and its still a rotary!

lemme rephraise myself, I now have an AE86 that I'm putting my high-rev unit into. I still want an RX-7 because it's a freaking rx-7. Now if I buy that 7 off my friend of a friend it'll remain mostly stock except for some suspension adjustments so that it suits me best. the rebuilt 99 13b will stay in the 7 if I buy that particular one later this fall.

Again, I'm so obsessed with the SR because of a lot of the same reasons you are all obsessed with the rotary. It's just my thing. rotaries are just your thing. If I had my way I would be buying an M4 hardtop roadster instead, but that's about 40k out of my price range.

I'm running two high rev N/A sr20's... I'm running custom headers and a 3" exhaust I built on both. No turbo. ones a FWD others a RWD. HP10 and AE86. the 86 isn't finished yet but I can tell you the stats of the P10 if your interested.

again, if i do buy my friend's rx it's going to stay the way it is engine/drivetrain at least. sequential 13b. That'll be my toy car. the P10 is now the DD, used to be the race car, now the 86 is going to be the race car once it's done sometime this spring at latest. I put up with hell on the street driving the things I do. I hate kids these days. You just gotta teach them there place on the sweeper exit. on the curb. well, over it technically. anyone with me on that one?
