i have a 98 prelude and i just bought a 93 twin turbo rx7 motor.
i am taking out the honda engine and putting the b13 in. anybody think i will have any problems with this. your feedback and comments are appreciated.

 

Prepare yourself for some hostilities.

 

why??

 

Um, so you own an RX-7 but you want to know if we think you can put a b13 into your prelude?


I am guessing you want to know what is involved.


There are a few honda people here. sorry i am not one of them..

What the hell is a b13? Are you talkingabout the 13B-REW? If so then, yeah good luck with that one.

 

well then can someone help me out. im just curious if im gonna have a pain in the *** job or not.

 

i think it would be cool. mounting the engine to the tranny is going to be the main problem, followed by engine managment and so on.

 

i saw a 3rotor in a chevy blazer once (very cool) so anything can be done.

 

oohhh, ok,.. you want to drop a rotary engine in your prelude..

Ok there are a lot of problems

1st honda engines & trannys spin backwards..


So you would need to do a porche transaxle or something.. and custom mounts for everything..


It could be done, but it would be a total waste of money, unless you really like being unique..


-Zach

 

the rotary i small enough i think that i should be able to put in in transversly. so that the tranny and engine connect. a new ecu maybe???

 

No, the honda tranny spins backwards.. it will not WORK.. You would need to change to a VW tranny or maybe a porche one...


-Zach

 

i know but i mean the position would not have to change.

 

i should just spend the extra loot and get the freaking rx7 trans to match. duh that i know would work

 

Well, since the new tranny is not likly gonna be transversly mount. yeah it will...


And then you have to figure out the suspension..



I would guess it would cost around 10-20K if you do the work yourself.

 

Nope, cause then you would have to modify the enire body of the car, because you would need a transmission and driveshaft tunnle.. and you would then need a rear end, because RX-7s are rwd..


-Zach

 

You should spend the extra loot and by an RX-7 if you really want a rotary powered car..

 

daaaamn no im out of ideas. i love that friggin engine and i want it in. any other ideas.

 

Not with a honda.. it would be too much work...

 

If you did the swap, the 13B-REW is from a FM/R (Front-Midship Engine/Rear Drive) vehicle. Correct me if I'm wrong, but even if you bolted an RX7 motor/trans combo in, you'd only be getting a single output from the trans. One-wheel drive anyone? Not to forget, the RX7 trans is long and skinny, I think it would be impossible at best to make this fit while allowing a CV transaxle (for suspension movement) to be adapted... You could, possibly fabricate something to bolt to the Honduh tranny and just run in reverse all the time, since the honduh tranny spins backward.

Oh, and the RX7 trans would have to be an Auto, since the 5 speed shifter would not line up... unless you're a master fab'er

Why don't you just get the freaking RX7 to match?

 

do you have to be a smartass thats why im asking for help..i dont want it from you though. least some people can be a little nicer.

 

I'm sorry I hurt your feelings. You're asking how we (collectively) think a 13B-REW and trans might fit into a 'lude. All I'm saying is, with any RX7 tranny, you'll only get one wheel drive, and the tranny probably won't fit, unless you were to fab custom suspension pieces that move the axle hub out a good 8 inches at least. But still, only one wheel drive. Unless, of course, there was a custom differential made to change the output of the RX7 trans.

That reminds me... FWD vehicles have a diff built into/onto the transmission.

I don't think there is really any feasible way to mount this.

Don't get an attitude with me. We're all here to help, but you're asking a pretty inane question.. Like grampa said, "Prepare yourself for some hostilities."

 

i think you should do it

 

I know what it's like to get an idea and then you really want to stick to it but all these people are telling you this is going to be a pain in the *** and not worth it.
If all that money is worth it to you then go ahead it's up to you
Why would you want just a 13b in a prelude? The reason why our cars are fast is because of the turbos. The 1st and 2nd gens except for the tII are without turbos and not really competing with us.

this is hands down a horrible idea I would rethink the point of this.
Just pick up a 2nd gen for a few thousand and get a prelude body kit
