Just wondering what you ppl think about a small block V8 in a 87 RX-7 GXL. If anyone has ever considered (sp) doing this or have stumbled across sites with anything to do with a V8 swap in a 2nd Gen RX-7 please share some problems i might run into, or websites with helpful information on the swap, preferably a Ford 302 (5L) or a chevy 350. Thanks.

welll... i dont just want any sluggy old V8 in there, i want an Aluminum high flowing head, Fuel injected all the stuff V8, 350whp minimum.

edit: iron or aluminum block, so if its a 302 it will be iron, if its a 350 it would either be a LS1 or an LT1 which both come with a style of vortech heads. (good flowing heads)

The LS1 is a kick ass motor. I got it in my boat :D

i thought the reason of the RX-7 was for the rotary...now putting pistons in it...doesnt that just kinda change the car's purpose

Rotisseries are really expensive to have rebuilt, the only Rotissery i would get would be a 3 rotar. then again, expensive and rare.

well it does change the car.. not so sure about the purpose.
there was an FC that had a small block in it at the autoX's last year when I went and it was pretty dang fast.

I'm not sure how much weight it adds to the car, but i don't imagine it's too much to affect it greatly.

people do things to make their cars more interesting. granted it's a different feel from the rotary, but some people like the fact that it's more reliable -- although it guzzles more gas.

i remember coming across an FC on the net that had an SR20 in it... just depends on what floats ur boat i guess

if i had an rx-7 i would TRY to keep it rotary, but on another note, sp engineering in the states have a FD w/ 2JZ in it...

It's a pretty common swap actually. There are even kits for it..

Why bother, a bone stock 13bt with a t04e will make power than any of those combinations, and still give you 33 mpg on the highway..

Yeah, if you wanna 350 go buy a camaro..

Is that a maytag or kenmore rotissirie?
Yes 3 rotors are expensive, but rotary's are actually quite reasonable to rebuild, if you shop at the right places..
You have no cams, valve train, studs, lightwieght forged rods, forged pistons, intake manifolds. valves jobs, deck cutting , crank grinding timing chains, etc etc to buy, you have about 16 o-rings, 6 apex seals, springs, side seals,corner seals, and some work with a diegrinder, or about 700.00 worth to make a 13bt into a strong street motor, if you reuse rotors and housings, the housings can be had for about 500.00 each, and 2 rotors can be had for about 500.00 if you need them, the stock mazda stuff will take over 400 rwhp of abuse, or you can buy a j-spec for about 1500.00 with tranny, and just put 15 psi of boost to it..
But then again, I biased...maxt

well, i think im gonna just try a Ford 5.0 HO EFI out of a mustang. and i'll probly have to try a rotary some day, but i think this would be a cool project for now if its done right.

Don't be suprised if a stock TII blows you off with that combination..Maxt

From what I have seen, and heard a first Gen with a stock Ford 302 HO will run mid 13's with simple bolts on's your 12's. I dont know of many stock cars that can hang with that. As for that in a 2nd gen i dont know. I would say do that to a first gen you dont even need to change the front crossmemeber just pull it out and do a 180 with it and it fit. (FREAKY). Also for SoloII i belive they run in E-Mod and have been faired rather well there.

I have seen an RX-7 with a 5.0 that was slower than mine (stockish T2).

I have also seen the red ZZ4 RX-7 that kicks the crap out of every wankle at Solo at Race City.

Either set up is potent, if done right.

I really like the 13B, but it's kind of sad when you can count about 20 blown up motors between you and your friends.

the V8 will weigh a ton more than the rotary will, which means youll need more power out of it to compensate for it. and with that V8 your handling is going to suffer.

For the money that guy though put into that car to get the v-8 swap to work, he could have probably had a faster rotary powered car in the end, the rx-7's he goes up against don't have the money dumped into the suspension and brakes that he does...
I talked to him once, about his car, in the end he spent way more money than if he would have stayed with the rotary, thats the thing, yes on paper a 350 chev is cheaper than a 13b, but after you buy a a built 350 chev, fuck around with the mounts, drivetrain swap, driveshaft, suspension, you end up spending way more than if you just did the car right with a rotary..My car has more rwhp than his does.. :poosie:
Loose, I could probably give you a higher body count of dead 350 chevs over the years than 13b's... Maybe you should rephrase that statement to say you have some friends that shouldn't be tuning rotaries..:)....
I lost a motor last year, the motor design wasn't the problem, it was the rebuild job that was done it that was the problem, don't confuse the two....Max

Hahaha

Ya hard for the rotor to seal properly when it's missing corner seals, side seals, and the groove milled for those stupid 3mm seals is as straight as the guy serving pizza's in the basement at SAIT. It's hard to believe that motor ever ran given what it looked like on the inside.

The s-shaped apex seal grooves were killer...

Loose, this is what you should do to your car...
