ENOUGH BULLSHIT !!!!!

Billet intake, oil pan or motor mounts....FORGET IT !!!

They're using the FD rear plate, FD motor mounts, shorten stock 20B intake and custom Al oil pan to clear the PS rack......that's their conversion !!!!!!

They claim to have a 20B FD running 800+ rwh.....BULLSHIT!!!
They claim to have run 9s with one......BULLSHIT !!!

700 rwh 2 rotor FD's....HAHAHAHA....BULLSHIT !!!
4 rotor engine ?????? HAHAHAHAHAHA....BULLSHIT !!!
They barely made over 1000 hp with the MX3 and that with alot help from Nos and those are flywheel #'s!

Ask them how many addresses their business have been thru ???

Mike....Sorry you got yourself involved.....and I hope those are not your parts going into that RX8 !!!!!

Wonder if they blew the motor in that RX8 w/ Nos !!!!

Damn.... I could go on....
Can't believe there's barely any Rotary shop that could be trusted in the NY/NJ area.......and there was so many.

If this is true it really sucks, @ one time they were trying to charge me $7000 just to mount my 20b in my car with their "special motor mounts and oil pan". But if you think about it, it would explain their claims that with their conversion you could swap back and forth between the 13b and 20b whenever you want'd and why they said that a new subframe was not need'd and there was no bumpsteer. The only difference between the 20b and 13b rear housing is the motor mount points and if you but a 13b rear housing onto a 20b it would bolt up to the stock subframe the same as a 13b and with a custom oil pan built not to bump the steering rack it would not need to be moved and the results would be...................NO BUMPSTEER. It would also explain their reluctance to just sell the pieces as a kit. I'm not saying this is how they actually do their conversions, but it does make one wonder. If you don't mind Enoughbullshit would you tell how you know about this?

I'm not an expert in 20B conversion.. but last night talking with John (20B 3rd Gen), made me think of it..

I think EnoughBullShit might be right about this.. Hiss idea about using rear 13b rotor housing completely make sense.. By my understand is that tranny and all just bolt straight up.. because of that concept, this completely make sense.. WOW!! This is going to change things abid.. Oil pan issue should be pretty easy thing to custom make..

EnoughBullshit, Please post again.. I would like to hear more about this and your thoughts on this conversion issue..

crispeed

The ports on the 20B and 13BRE are much larger than the ones on the 13B-REW. You'll have to do extensive porting to the rear REW housing to match the 20B one! Not that it can't be done but it's not just a simple swap.

jim labreck thought about doing that in like 98. if you read about his car it comes up

That's true, but like you said they can be port'd to match, if your having the motor built, which is part of their conversion, it will be done anyway. I'm was not saying it would make the swap super easy but it is greatly simplified compared to fab'ing a new subframe and mod'ing the spindles. Right!

Enoughbullshit

13B-REW ports are smaller but porting them will take care of it....

Remember their uploaded pics......check out the one where the rear section of the 20B is covered with a blanket or towel !!!!

There's someone on the forum doing it this way....out of the country, I believe.

Trust me...I've seen all this bullshit with my own eyes !!!

Your right! Dragon is the one doing it this way. He also has a pic showing his shortend manifold. The only thing he has done differant is use the stock oil pan and modify the stock sub-fram for clearance.

tri_tam

hahah my friend put a 13b-re in his 93 fd
just change the rear plate and the oil pan
didn't y'all fd just need just need to heard this.

BFD.

jamesdeanrx7

can someone please explain how this will work how do you port the rear plate etc. and how much easier will this be

rx7tt95

Or...just buy the Cosmo 13BRE into FD motor mounts like I did. You can swap back to an REW by simply replacing the metal "arms" which attach between the engine and the actual rubber mounts. People have been using the rear FD plate for years. Ask Pettit.

The way MVA mounts it is "Pettit" style w/o the subframe. It's still forward however and the Autotech version mounts the engine back further (still trying to figure out how they're doing this with the full 20B engine/oil pan and no mods to the subframe). Definitely NOT worth $14K which is the price I was quoted. If/when I get my hands on a 20B, we'll see how it'll mount further back. Right now I'm having enough trouble with the RE and my overzealous porting. I'm now an expert in epoxy resin :-)

rx7tt95

James, to answer your question, when people refer to porting the rear plate they are enlarging the secondary intake runner which is IN the rear "plate". So you take an FD rear plate and "hog it out" til it's as big as the stock Cosmo secondary runner. That way you'll have equal flow for the secondaries across all three rotor chambers. If you do not port the FD secondary runner on the rear plate, it'll flow less air than the other secondary Cosmo runners in the intermediate and front plate. Not a good thing and makes it pretty tough to tune.

Again, I'd just purchase the Cosmo motor mounts as they're cheaper than a new FD plate and it'll take less time/money/effort .

Matt RC-Racing

Yip.. thats EXACTLY how we are doing ours, except we're also using a ~15mm sump spacer for rigidity and custom sump, of which we will make readily available!
Also a front mount as we're not keen on having all the engine weight hanging on rear mounts alone.. 13B not a prob, but 1/2+ as much weight again needs something up the front.

rx7tt95

You guys really think we need mounts up front too? Sure you have the two stock motor mounts, but the entire tranny also supports the motor. Does seem like a lot of weight though :-)

As for the sump spacer, do you mean an aluminum "brace" that sits between the bottom of the engine and the oil pan?

jamesdeanrx7

Rx7tt Thanks for the info man. where can you buy the cosmo mounts, and how much? and how much easier does it make the mount.

I cant wait to start on my project>>>>>>>>

jamesdeanrx7

OH ya Matt Rc- racing do you work or own the jap performance parts place and if so How much are they getting 20b's for???

Matt RC-Racing

RX7TT.. yes.. i strongly recommend a front mount, as its alot of weight is fwd of the mounts.. end of the day, it may be over kill.. but safer and sorry aye?

jamesdean.. yes.. own Jap Performance. The last 20B we got in was a known 'needs opening' (just as seals were stuck from sitting for so long..) that motor was cheap... got my agent sorting some more at the moment.. looking for 3+

rx7tt95

Compact Car Performance in Naples, Florida has the mounts. Not sure how much they cost. Their number is 239-354-0442. Let em' know I sent ya!

Essentially, with these mounts, the Cosmo 13BRE is a bolt-in affair (for the shortblock). One should be able to theoretically bolt in a 20B using the same mounts. You'd need that custom oil pan however.

Are you saying a 20B will be a "bolt in" project with these mounts???

rxman720b

Curious as to who in TX screwed you over and what was it that happened?

Red-Rx7

Derrick-

I think you know the story quite well, and it being only one sided. Regardless what HE thinks, I have it all in writing. Clear cut and simple. He may have been confused (giving him the benefit of the doubt), but it was illegal and unethical in what he did.

I started to file suit, but ended up dropping it for that the transactions occurred out of state and I would have to file in the state that the transaction occurred in. I didn't have the time to deal with it, and ultimately let it go.

I did file with the Texas State Attorney General, in which they proceeded to fight for my case for me. In a very shady response, HE knocked off 10% of ONE item and wrote back indicating we BOTH came to terms. All during which, I was in the hospital. When I read the letters from the TX state generals office, I laughed and set it aside.

I never slandered this place, nor spoke bad in public about it. I could have, and with all the documentation I have it would have been horrid against him. What is funny, is HE did make a few phone calls and try to cause me additional trouble afterwards with other people. Which was quite funny, for all they did was laugh and tell me about it. But I guess I was naive, or something.

Sometimes it isn't worth fighting, and I figured I would learn from my mistakes. LOL!!!!!!

Actually, I didnt know much about your situation. Or even who it was. All I know is that I am glad I never sent my car to NJ to have it worked on or I might have been in the same boat you are. I was offered a "too good to be true" deal and didnt feel comfortable having my baby out of reach way up in NJ where I couldn't see and touch it everyday. I know how I would have felt if that had happened to my car!! I did have Marcos port my 20B while it was out of the car getting rebuilt. He or the machinist did a fantastic job. I still brag about the quality of the porting in the photos of my rebuild!
Once again I am sorry to hear of your problem.
