has anyone done a 350 engine swap into an rx-7? if so please send me the details... such as what it took to get it to fit and what else you added. about how much everything cost. and any problems that you ran into. thanks a lot

ok i must ask why?? and what generation?? ok now for the facts yes its been done, please dotn quote me but its grannys speed shop or something like that sells swap kits for sbc's and the LT/S1 motors. just do a godle search for grannys speed shop and im sure you will find it. and hinnison supercars does them for LS1 motors as well.... and of course you can always do a motor plate or custom welding if your good with that sort of stuff.. now im leanin towards a FD when i say this.



As for how they run im not sure but im sure there quick, but the weight of a normal 350 chevy is going to be killer on your handling.. the LS1 bein all aluminum is about the same weight as out 13B's and people get good results with them. 2muchpwr i believe on this forum has one in the 10's with a ls1 t56 swap.. unsure of the mods tho... its a 3rd gen also now as for a 1st gen there is one here in my hometown with a 383 stroker on nitrous and a 350 tranny running low 10's but hes really really built up.. i wouldnt do a v8 swap in mine unless its a 1st gen only, i really like my rotary motor in my FD.



Hope I helped you out and again I am going to ask whats wrong with your rotary?? and if you have a 2nd gen why not swap in a 13brew out of a 3rd gen in it?? and i happen to have one for sale with turbos and all... 99 spec turbos to boot!!

yea you helped a lot. right now im looking into many different options. i learned that a v8 would push it up to about 350rwhp and not have much affect on the handling. with a 13b i saw it was more like 200? if thats the case then the extra 150hp would be worth it. and not to piss off everyone with a rotary, my 2nd gen has about 190k on the motor and a v8 would be a cheaper way to go as well... without all the options of course. i am kind of on a budget so i would be throwing in the v8 for more of a temp thing. then while i dont need a car to drive ill be building up the stock 13b and adding turbos and all the bells and whistles. at least that is the plan. how much are you selling yours for?



".... and of course you can always do a motor plate or custom welding if your good with that sort of stuff.. now im leanin towards a FD when i say this."



now im kind of a newbie when it comes to the rotary, not even sure what model i really have. the fabrication wouldnt be much of a problem, if i kinda new what u were talking about. thanks again

Many don't like the Idea of doing a v-8 swap into an RX just because will the rotary engine is the heart of the car.. I have never looked into doing one or bothered to look for a shop that sells the kit to do it. I do know that the all alum. LSX engine will add 60 lbs to the front end of an fc. This will effect handling and many other aspects of the car. Stock with the rotary engine the FC has a 51/49% weight dist. a v-8 will change that drastically pushing more into corners than turning into them.

Other options are good but here is just a suggestion..order new rebuilt motor while waiting for that change the clutch and add a light flywheel change seals in tranny and shifter bushing use some kind of new ecu (wolf 3-d, apex power fc etc..). Remove all the vaccum lines and other unnessary crap and have a good running car with a rotary.

hey, if your looking for 300+hp, then the 13brew out of a 3rd gen is your ticket, yah there around 220whp stock but thats an easy fix, just up the boost 12-13psi, 3" exhaust and your pretty much already there if not your darn close, and you can go way more than that if you wanted. 350whp is not out of the option if you go 13brew with stock turbos.. if you want to send me a PM i can try and explain a lil more in detail if you wish..

put a straight six in it rolling on 20's... then push it off a cliff

the 13brew is the twin turbo or the single? like i said im a newb. to all this. i honestly have no idea what im planning on doing, but all i know is that its going to happen around feb. with a tax return from my good uncle sam

REWs are the twin turbo engines. Like it's been stated earlier, you'd have an easier time swapping one in, getting the power you want, and not throwing off your handling.

agree'd and you could always get more power if you wanted by bolt on parts... very easy hp its all in tuning...

You're only going to get biased responses here.



Visit torquecentral.com for some good info, and see the classifieds over there, you may get a whole swap with everything you need for a good price. Many poeple have done these kinds of swaps with great success.



Also visit http://grannysspeedshop.com/, and read all the articles and information they have, there is a ton of information. The discuss handling characteristics, and ways that people have balanced their cars, if that's an issue you're concerned with.



I managed to give a guy my n/a 13b (just the bare block) and $350, and he gave me a rebuilt Ford 302, AOD, and the basic Granny's kit to bolt it into my covertible. I don't care about handling, this is my wife's convertible that I bought for her just to be a fun weekend car. A whole bunch cheaper than rebuilding my n/a 13b, or upgrading to a TII drivetrain.

Baldy,





im not biased at all. its his car he can do what he wants. Im just one of those guys that like to keep same stuff in the orginal car(s), thats all.. V8's make plenty of power and they are cheap. Im just sayin he can save lots of weight keep handlin and make about the same amount of power with a 13brew. if he wants a 454 big block so be it, its his car. ill try and help him no matter what direction he goes.. i just think the 13brew would suit him best and be the easiest swap. JMO tho.

I dont know why i didnt mention this earlier but in the for sale part a guy is selling motor swap mounts for this conversion into your 2nd gen for a 13brew..

with those mounts you can still use a 3rd gen downpipe and all and make things a breeze for you to make the swap... def looking into for your swap if ya go a 13brew route..

dude for the price just buy a 13bre from a cosmo it's cheaper twin turbo and you can use stock ecu and ****.

ok, i DO have a biased opinion, but if you want a lot of horsepower without screwing up the weight distribution too bad, why not go with a 20b? its twin turbo stock, and has a lot more potential than a 13bre or 13brew. just my opinion.

I dont know too much about rotaries and the such, but i do know a bit about v8 swaps (from my research on rx7s and Zcars). Its relitively straitforward, wiring isnt that big of a deal, and even less of a deal if you go carb. And to the guys talkin about REW and other 13b swaps, talking about powerFC and a single setup, i just want them to relise how much that costs. You can pick up a lightly used, 302, 351 (my possible route), 350, or 383 for less then the entire cost of a single turbo setup. And thats with the entire harness, pullies, and trani so you choose. 300 bucks isnt too much to ask for a 302, harness, ecu, t5, and pullies.





The basic kit from granny is roughly 500 bucks, driveshaft is another 300, and youll need a new rad and acouple other things including the headers. Granny's deluxe kit is about 1200 bucks with no a/c or powersteering, and 1300 with Since the rx7s are so much wider then Zcars, you got quiet a few header options, and ive seen 351 swap BBK full length headers on a 302 fiting just fine. With aluminum headers, manifold, and relocating the battery to the trunk, and with a fiberglass or CF hood you wont really be that bad off compared to a turbo rotary.



hope this helps

I just switched my stock fd hood with a fiberglass one and there is only like 5 pounds differance in them. nothing really thats going to help out a v8 swap to be lighter than a 13b, if you want to try you will need to start adding aluminum parts to the v8 like heads, intake and so fourth... then it may come close, unless of course you have a ls1 which is pretty much all aluminum....

also im just curious but if you do a 350 swap, and you use the grannys speed shop swap kit, with a normal intake cand carb would you have to worry about hood issues?? will it all fit under a stock hood?

god forbid you would want a reliable car.

Certainly you're not one with a biased opinion. https://www.nopistons.com/forums/pub...>/rolleyes.gif
