Waht do u guys think? rx-7 and an RB25DETT? Im strongly considering trying this engine swap as soon as i can find a really cheap 3rd gen rx7

 

1. There are no cheap FDs.
2. It's either an RB26DETT or an RB25DET.
3. I think it's a wasted effort because, as legendary as the RB series is, the engines fail just about as regularly as any other. They are NOT, as some have come to believe, bulletproof wonders like the Toyota 2JZGTE. You'll spend a lot of money to throw the weight of the car WAY off (if the I6 fits... kind of questionable...) and then struggle to maintain respectable power levels.

I'm not saying it's not possible, but I think it's a bit unrealistic. Spend less money to get a well-maintained FD and tune the 13B-REW for the same power levels.

 

oops i ment RB26DETT i accidently hit the 5.

Yeah theres cheap ones. ive seen some go for only 2k on ebay and a bunch of other places problem was they were all to far from me so the shipping cost made it not worth it.

im pretty sure the engin will fit ive heard of people putting a 5.7L V8 in so im pretty confident a 2.6L l6 will fit

 

oh man some one close this thread before it gets out of hand....

 

Show me these FD's goin for 2k on ebay, I'd love to see them Not a fan of swaps myself, but it'd definitely be an interesting project.

 

who the hell would want to put a nissan motor in a mazda!

....

 

btw...rb26 wont fit without VERY extensive mods...its to long, and quite possibly to wide (im a nissan man i would know)

 

ive poked at SR20 FB ideas before. i like engine swaps, im not a purist. BUT i still like rotaries. Id probably so a rotary S13 and a SR20 RX7 (at the same time!!!)

 

There arent any FDs up that cheap right now but since i started looking about a week ago i saw one 93 go for 2400 in tennese and one go for 2050 in north carolina but i didnt really feel like paying the shipping for either of theses.

what do u think on the mods to fit the engine? u dont think custom mounting brackets will be enough?

 

your a little mis construde on the liter #. just cause a 5.7 fits, doesn't mean any thing under that liter will fit. The problem is its inline, so its very long, then the RB itake manys go really wide. You will NEVER get a 2 or even 3k FD on the west side of the US. Your looking at a $4k shell dude, there are a reason cars in NC and **** go cheap without engines. If you have $20k, youll probably complete this swap to respectable power IF its in the realm of fitting in the engine bay.

 

does anyone know for sure if it can or can't fit?

 

Yeah, it will fit, but you looking at a lot money to get to work.

 

i would say that there is a possiblity that it might fit width wise, however to go length wise i would say you would either a) have to notch the firewall or b) take out the radiator support and make your own custom mounts for FMIC and the rad. Or if you were smart to make things fit nicer, do both.

 

you'll also run into a problem with the steering components

 

Granny's Speed Shop makes a kit to swap the Nissan VG engine family into a 2nd Gen, if you'd rather try that.
Just a thought.

 

thanks for the input guys. i'm glad somebody gave me real answers instead of just goin "ROTaryS r the PwNZORS!! piSTons Suck!" like mazda guys usually do when i even bring up the idea

 

If I remember correctly "Import Tuner" had a 2jz FD in their mag one time.

 

There is someone on this board trying to sell an FD with a 2jz in it. Not completed though.

 

Here, I founded the link FD 2JZ
