i didnt c a search topic that matched so i was wondering which one should i go w/? and who's got the best rebuilds or new motors for sale as far as quality? or are they all the same? also when people r asking about turbo's i read a bunch of forums but noone says what motor they are askin to put the turbo on so ill ask this even tho someone is gonna jus tell me to search yet i have, how is a 13b gonna handle a t88? im sure a 20b will work good w/ a t88 but not sure bout the 13b.

 

up

 

Why the hell wouldn't you go with an extra rotor?

 

first of all, im new to rotary's, second of all, the price is a bit different im sure! third i dont kno the diff in power u can get w/ a 20b over a 13b, fourth dont kno how much work it takes to make a 20b drop in my rx-7. way to answer the questions tho, thanx for the input, so far ive seen like 2 people who kon what they r talkin about on this website.

 

HEll dude there is a 20B section. You need to search better. But I will tell you know that doing a 20B swap is very expensive, at least $15,000. The 13B-RE like the 20B is going to require motor mounts from either K2RD or Speed Machine Performance, or custom make your own.

I would suggest that you just swap in a S5 13BT with a fairly large street port and a single turbo.

 

The 13BT (which is the model in Turbo2 cars) can handle a lot of boost if the engine has been built properly, there are guys who run 20+psi on that engine and get lots of HP out of it.

The 13B-REW that's in the 3rd gen rx7 is a pain in the *** to get into the 2nd gens and is not recommended.

The 20B-REW is a 3 rotor engine that will cost you at least 10,000 to get it up and running in your car. You'd have to go after market with this engine since it was never brought to american in a stock car.

All of this information has been talked about on this forum numerous times, you claim you searched but if you didn't find anything i'll call you an internet n00b as well as an rx7 n00b.

 

Stop spreading this misinformation! He didn't ask about the REW there is another engine with a similar name but it is an RE.....NOT REW. The RE was the 2 rotor cosmo engine, it was also twin turbocharged.

dang it, i wanted to say that, lol. i also read somewhere that it will fit under the hood of an fc, unlike the fd motor.

 

Yeah fritz i know, but the kid was asking about the 20b, which is the 20bREW.
The 13B-RE that you're talking about is pretty hard to get and it's not much better then then the 13BT in the T2 cars so why bother?

 

I have to disagree. I'd say the 13bRE is probably easier to aquire than the 20bRE -- or at least as easy. (I've got 2 13b REs).

And 'not much better' is probably pretty subjective. One needs to do a search on the topic and form their own opinion. Many will say that the HP potential of a 13bRE is higher than a plain 13bT -- but it probably requires more work & $$ to accomplish it due to custom mounts and ECU limitations.

The 20bRE is the ultimate in rotary performance IMO and has the highest HP potential -- and the highest cash spent potential.

 

that hurt my brain to read.

 

Half this topic hurts my brain. All this information is easily available by searching the 2nd gen forum on the engine you are curious about. There is also a dedicated 20B forum.

 

take a look at this web site it tells you what all you need to put a 13b re into a fc i am planning on doing the same thing hope this is what you are looking for http://fc3spro.com/TECH/SWAP/COSMO/13b-re.html

 

if you dont know which one to choose i would strongly recommend stickin to a 13b-re or better yet maybe even a 13bt if u dont know too much about rotaries yet .... even the 13b-re can b a difficult swap to some. but unless your ready for ALOT of work/money and u can have your car in the garage for along time without needing it .. then i would maybe say go 20b

 

You didn't do a seach or didn't do it well enough.
If you did, you would've found references to my website which covers BOTH swaps.

Personally, I think you're in over your head.
The non-turbo FC is a BAD place to start from, and there is no way the NA drivetrain can handle the 20B power increase.

i wouldnt even trust the n/a drivetrain with a 13b-re ...

 

wow answers. thanx people. and yes i did a search and when i got my results from teh search i opend the forums and it sayd......"do a search" to the people askin in the other forums. so maybe they should sticky em, and yes i already said im a rx7 noob, internet noob not quite, sorry ive been into fords for a bit and i picked this car up cuz i got it for a grand and i wanted a stick, my stang is auto, and ive had the rx7 about 15 days now, and i didnt c a 20b section in here, i was lookin in the second gen section only for info, and also when i do searches it comes up w/ other gen's info. so whos got the 13re's for sale and whats the prices? and yea after i started this forum i found more topics that gave me some info in the "similiar threads" at the bottom.

 

o nvm, that site was very helpful thanx, hmm. i might check out the 13bt motor, gotta find a link to that now. =D

 

wow.. cant find a link to the 13bt, wtf, i found stuff about turo's for em but not just basic info and where to find one. this search option sux.

 

From my personal experiences. A 13bt can be sourced. The real question is, which one would you like to use? The S4(86-88) Turbo has less horsepower than the S5(89-91). I personally am building my n/a to get some knowledge & hands on experience with rotaries. Later down the road i'll just buy an S5 Turbo 2. Seems to be a whole lot easier than trying to get everything swapped over. Your best bet is to find a wrecked T2 that has what you need in it. A 20B is a great motor, as is the 13b-RE, but since you are new to it. I'd suggest the 13BT which one is up to you. Hope all works out for you.

If you can't find a wrecked Turbo 2, you could always check these places. They get 13BTs in on the norm.

www.fc3s.org - most of their are from Japan, keep that in mind
www.mazdaracing.com - also from Japan
www.pineappleracing.com - You'll just have to see for yourself

 

Oh yeah, as far as general knowledge. Check the faq in the 2nd Gen section

 

hey thanx man. ur very helpful. its appreciated

 

ooooo i forgot to ask, i doubt it does but...... when u purchase a 13bt thats rebuilt does it come w/ the turbo? is there anywhere i can find one new instead of rebuilt? yea i like the single turbo setup a lil more btw. =D

 

[QUOTE=Parastie]The 13BT (which is the model in Turbo2 cars) can handle a lot of boost if the engine has been built properly, there are guys who run 20+psi on that engine and get lots of HP out of it.



wat turbo are they using?

 

No, unless you sent them yours originally.


Are you talking about a NEW STOCK turbo or a large aftermarket turbo???
