i dont see why not

realistically speaking, it is very cheap and fairly easy to swap a v8 in a seven, and considering the amount of potential in something as simple as a 350 SBC, very easy to see why one would do it


only reason they dont do it in japan because american parts very expensive, at least, from what I understand

Funny, one of the best rotary mechanics, engine builders i know is from New Jersey.

Stock LS series motors with no modifications are a joke compared to a turbocharged 2 rotor. Not only do you need to spend all the money to swap it, then you gotta build it to take on a well prepped 2 rotor.

All money and power considerations aside , I still wouldn't want anything but a rotary in an RX-7...

If one does not want the rotary, why get an RX in the first place? confused2.gif

The easiest way to not have to worry about your rotary motor is to.

A) Take care of it and don't be a tool.

and

B ) Learn about them so if something does mess up, you can fix it yourself.

Buying a car you know nothing about is automatic fail in the first place.

Not entirely true.

Buying a car that you have every intention of learning about is not too bad. Everyone has to start somewhere. smile.gif

Yep, I can vouch for this one from experience.

I've got a wonderfully reliable problem-ridden car. If you told me back in April that I'd know as much about cars as I know now in less than a year thanks to this car, I'd have laugh at you.

But sadly, it happened to some of us, when we were going to Great Wolf Lodge a long time ago, the Legend ran dry just about the entrance of the exit. >_< How gay was that?

Thank god we carried at least a 2 Gallon Gas Tank with us and drove to the nearby gas station. >_<

Well, the driver's side fuel level sensor is either broken or dislodged (yes, my car has two level sensors), so I don't get accurate readings on the gauge all the time.

yea, but a rotary wont get 20+ mpg

or wont be able to move around @ 2000 rpm's


god i sound terrible, but realistically think and shopping around will show that a LS swapped 7 is worth it, even stock

i figure this...

rx7 shell - $300

ls1 + trans + ECU - ~$4500

~290 WHP // ~310 RWTQ stock

should be able to hit 13's all day


OR

Rx7 shell - $300

TII engine + trans + ECU ~ $2000

~180 WHP stock

hitting 15's all day


but wait ! rotary has an extra $2500 !!!

and yes, you could use it to get faster...

intake/exahust (3" turbo back) - $800
upgraded fuel pump - $120
720cc secondaries - $100
FMIC - $600
wideband - $200
SAFC - $200

just with that, you can get up to ~230 WHP

that will get you into 14's

** of course, all these things mentioned are assumed by doing your own work and also include not having to rebuild the motor

seems to me, comes out about even, except you get better gas mileage, torque, and the awesome ability to be able to go to autozone and get anything you could ever need !

Contrary to popular belief, Japan does make their own V8s. There must be another reason why they don't drop V8s into RX-7s in Japan tongue.gif

Japanese V8 > American V8

My opinion of course. I'd love a 4L V8 Toyota Soarer biggrin.gif

Most japanese V8s are heavy, anemic, expensive and hard to modify.

American V8s INVENTED the aftermarket.

I hope your joking

any reasonable person should be able to see that having the ability to make 300whp for $1500 would be a wise choice

cant do that with a japan v8, let alone, ANY japanese motor

Since it all goes in together, it's no more work than swapping in a V8. And guess what? The 4G63 is Japanese.

V8's?

I would do it right :

http://www.ultrastreet.net/engines/402_realstreet_alum.asp

$8K for 525 horsies. laugh.gif

so you just pick up a 4g63 block for free ??

did a little searching myself

found this guy

http://www.kcsr.org/viewtopic.php?t=186494

pretty good, cept it was on a 18g turbo and a aftermarket manifold

close, but no cigar

and, i am no expert on 4g63s, but seems to me this is your motor

http://www.sunrisejdmmotors.com/engine_det...hp?id=79&page=1

also found this useful and interesting

http://www.dsmtuners.net/sub.php?page=1gtstage1power


seems to me, you get about 250whp with some basic mods for about 2k, which is not bad at all, but still a bit behind a completely stock 350

I almost forgot the Evo fuel pump there. That'll add a whopping $30.

See, there are two ways to do a 4G63 car, one of which is looking at the shops for parts, the other is to go through your local clubs. The latter is cheaper, by far.

What I meant by rebuilt 4G63 was, in fact, an entire engine. Head, block, crank, manifolds, the works. In fact, I was seeing some rebuilt 7-bolts for around $400 late last year locally. They're cheap as hell if you know where to look. Hell, you could buy a blown one and rebuild it yourself for less than $500. The turbo and injectors? Exactly what I got for exactly those prices. The clutch was an over-estimate because I got a serious deal on mine, practically at acquisition cost. If you want to go cheap on the tuning, an SAFC can be had for $100. I can quote you low prices with valid real-world examples all day. It can be done for $1.5k or less. Trust me.

And here's your 300 on basically the build I listed: http://www.dsmtuners.com/forums/tuning-eng...mbers-here.html

About halfway down the page here, you can see an attached 2-run sheet that achieved 350 on a small 16g: http://www.dsmtalk.com/forums/showthread.php?t=208193&page=4

well it is the same for 350

i was putting down shop numbers

realistically, you can go to the junkyard, find a camero, buy the engine + trans for $300-$500 and you have a 290whp for stock

and in the link you posted, the guy has a FMIC

and i believe it is safe to say, you dont run around all day @ 19 psi


but lets throw this into the equation

I can get a SBC from the stock 290whp to 400whp with about $1500



and btw, if you havn't figured it out by now, i am throwing a 350 SBC in my car with help from friends with lots of experience in chevys and planning to run 400whp...get 20mph...and be able to move from 2000rpms

Sell the car and get a C5 Z51 Corvette because they are so damn cheap now.

You will save money in the end, and have a better "turnkey" sportscar.
