Motor Swap
 

Is there any way to do a 13B motor swap into a 2002 mazda protege ES? $ is not a problem. i know i will have to make it rear wheel drive, which calls for a custom driveshaft. but is the motor swap possible? I've been thinking about this for a while and it would be bad ass if it was accomplished.

of course it can be done if money is no object...you'll need quite a few custom parts and it is totally not cost effective for just a 13b...maybe a 13btt...but a 300+hp rwd protege revving to like 9K would be quite a site to see!!!! good luck

yes it would be a sight :D...i meant the 13btt though. how much do you think it would cost to accomplish this? i'd like to decide if i would have any more $$ for items such as bigger turbos/single huge turbo, or something along those lines.

corrections:
you want the 13BT
or the 13B-REW
or maybe even the 13B-RE

well while ure at it you might as well go 20B

yeah well with money being no object anything is possible....

well yeah you would have to make it rwd.... so hmmmm...

how bout trying to get a hold of the 4wd drivetrain available for the proteges in japan and i think australia....then you will have to customize it to make it rwd, or you can keep it 4wd

well it would mean changing the undercarraige, well not changing but doing some custom fab work to get it to work

I think that a 20B would be much more better for the project....well better potential and reliability.... and the torque is alot more.... considering the project with a 13B would be just as hard because fo the custom fabricating and all, so you might as well just gow ith the 20B

you see my dream car would be a FD3s (3rd gen rx-7) with a 26B in it, (or really any 4 rotor configuration, like the 22B) NOW thas my dream

I'm a rotorhead so yeah.... a rotary would be my choice over any piston engine :D

There have been companies that has made a 6 rotor configuration.... and they are also working on a 9 rotor i think

yes you are right. you are bringing back a lot of rotory knowledge here. i wanted a fd3s rx7 myself. a 20b 3 rotor motor would be awsome! however, a rotory motor in something like a mazda protege, would be so unexpected. that's somewhat why i like this idea more than buying an rx7. i wouldn't mind leaving the 4wd protege chassis however the driveshafts are weak and are only rated to about 250 hp from what i have heard. could get a custom driveshaft though....all wheel drive rotory protege would be rediculous!!!:eek: i think that that would be way better than buying a turbo for this motor by far. and aren't the 20b's NA?

Just find an old RX3, I think most of them left in existence are running in Solo II anyway.

converting a 4wd tranny to rwd is a big waste...in 4wd tranny the front end bears the brunt of the power so the rear end would be to weak to hold rotary power, it would just break

Off topic: prtygy22 where is Pickerington, OH?

Oh my bad... i don't knwo much about 4wd trannies...

well i geuss he will have to go custom all the way then....

this is a big project.... ALOT of fabricating, and ALOT of money....

and ALOT of time without a working car until it is done...

but the results in the end owuld be awesome....

while ure at it maybe get the rotary streetported, and maybe even go single turbo on it.... well there are ALOT of mods available for the rotary... so there is alot to do

Pettit sells a 20B with stock turbos (twin-turbo)(that are a little modified) and it puts down around 500rwhp

now imagine a protege with that kind of power... 500+ whp damn :eek: :eek:

No the 20B's had the same sequential setup as the FD, except with slightly different turbos....

The FD3S has two HT-12s as the turbos

The 20B (found in the JC Cosmo) had an HT-12 and a HT-15, with the larger turbo as the primary turbo (fed by all 3 rotors) and the smaller secondary turbo fed mainly by the last, rear rotor after the transition....

you sure about that??? I may be wrong but i always thought in a sequential twin turbo,the first turbo was smaller so it spools faster, and the second is larger for the big top end power....

yeah i'm sure.... its cuz the JC Cosmo wasn't a top end sports car liek the RX-7.... so it wasn't tuned for power....

liek even tho it is a 3-rotor, the stock configuration was only rated for i think 220bhp

and the RX-7s 2-rotor configuration, made 280bhp (well the series 7(or 8 cant remember :p )) otherwise 265bhp

but when you tune the 3-rotor, you make loads of power, and a much better torque curve

also for stock, its more tuned for low end to mid range driving, so you can get the most power outta your low - mid range.... and it still has the small turbo for the high end, for a little kick up there.... but mainly "STOCK" its more tuned for low - mid range power

well, first off pickerington, ohio is about 20 minutes east of columbus. secondly, through some discussion with a friend of mine who also is very into cars, we have come up with a solution as to what needs to be done to accomplish this. i am going to need to buy a full rx7:chassis, motor, tranny, everything(preferably wrecked with no frame or motor damage). then we will customize the frame to the size of the protege. have customized axles made, then drop the whole protege body and interior and everything onto the customized rx7 chassis. after that we would be set. this project we estimated to take about a year.

(friend of mine drives a stock car at columbus motor speedway, he built the car himself...and some help ofcourse, and it was a bad ass car. that group knew how to fabricate everything.)

well in the end, it would be one bad ass
"Rotege"
thought that name would be more appropriate with the rotary :p :p hehe

haha... :evilgrin: ...! Oh man! that's awsome, i will have to customize the Progege emblem to say Rotege. maybe i'll just drop the 'P' and make it look like it was an accident and just broke off or something.
