could i get some imput about the quality and value of the stage 3 rebuild for my 12a from rotarywarehouse.com? i was looking around for rebuilders and they seem to have the best prices and seem pretty legit. they say a "racing port and polish", does that mean a basic streetport? anyone have any advice toward this?

 

Dunno about rotary warehouse but i will give opinion. Go with the bigger names like RB or places like that, you KNOW the quality will be good and thats why they are a bit more. Or if you can find one of the guys who has done porting before in your area, usually we will try to help out a fellow rotor head

just my opinion, know it didnt help you out much tho

 

I wouldn't rule them out unless you cannot find anyone who has had an engine done by them. You know you can find heaps of review on RB, so they're a viable option. If this company doesn't have reviews then I'd look it elsewhere.

 

Dont forget about me as I can do the rebuilding too...

id love to have someone around here do it, but there isn't too many people in south dakota that even know what an rx7 is. i wish i had a nickle for every time ive been asked, "is that one of them nissian z's, thats nice."

 

as for atkins dan, i assume you run the atkins rotary page and its nice to talk to someone that i keep bumping into the name left and right on the internet when researching rotaries. can you give me a ball park for a nice rebuild with a street port?, i just want to do that, some sidedrafts and an exhaust. what ever build you'd think would work out best for that. i have a daily driver to so street/strip is where i was aiming.

 

i need your help too. what jets should i run on a 1/2 BP with a 7" s/c and a holley 650 dp?

 

also, ive built a b16si-rII/crv20 motor for my civic i sold so i'm no stranger to that, but how hard and what specialty tools would be needed to rebuild my rotary myself?

 

Download the FSM and check it out:

In my opinion, there aren't really any specialty tools to rebuild (other than some of what you might use on a piston engine). I guess the main one is the 2-1/8" socket for the flywheel and enough muscle to get the nut off (torqued to over 300 ft-lb). I find the rotary simple to rebuild. Easier than a piston engine in my opinion.

ooow, good posts.

 

https://www.rx7club.com/showthread.php?p=7396533 , after seeing this i think i might pass on rotary warehouse

 

I rebuilt my Turbo II engine on my kitchen table. The most difficult part (IMHO) was managing all the seals. Otherwise there was nothing to it. I rebuilt some 12A's after that engine, it was not bad at all.

 

I'll have to keep that in mind, if I ever get started on my 10th Anniv. project.

 

If you are brave, just get the rebuild DVD and DIY!

 

if you were willing to send your block to sacramento then you should talk to www.mazdarecycling.com he was going to sell me a GSLSE block for 1600 w/o core, so im sure he will give a decent deal on a rebuilt, and he has all of his rebuilds done by chack point racing.

 

i thought in that thread posted it said they were the same company....? or did i miss read it

 

I saw that too.

 

i didnt read the other thread until now, but i talked to mazdarecycling about a week ago and he told that when he was using RW he had nothing but complaints, so he went back to check point and havent had anything bad since, he also told me that mazdatrix ordered an engine from him, which now that i think about it doesnt sound right but who knows you can contact mazdatrix if you and comfirm with them.


i personally have not had experence with them but i was thinking about it , buying rx8 block, i just passing on info that i was told.

 

okay never mind after seeing that thread **** that go with mazda trix or rb or somthing if you got the cash

 

i was going to mention that thread as well.

:AA:

 

i have a 12a rebuilt by atkins and it runs great...they do some good work..or you could by their rebuild dvd and their rebuild kit and do it yourself..

 

There is a BIG differnece between assembling an engine and building one. If you just want someone to assemble the parts for you, there are several folks who can do that and cheap too. If you want an engine built, particularly with porting, you want someone with LOTs of experience and a flow bench. True builders, like Atkins, RB, MAZDATRIX, Arizona Rotary Rockets, et al, measure, test and validate their builds for proper tolerances and flow characteristics. A porting template is only as good as the testing behind it. As Paul Yaw says, if you aren't measuring, you're guessing.


If this doesn't make you stop and think about who you choose to do your build, well, I think that speaks volumes: http://www.yawpower.com/Flow%20Testing.html

Good Luck!!!

 

I know this is a really old thread, but I had to chime in. I have a stage 3 13B from Rotary Warehouse. It's been in my car since 2007, with no problems. I know they are gone now, but My engine has seen 9500 RPM on a regular basis. It's the only part of my car that has NOT given me problems. It's even carbureted, runs strong and it's even been run way too hot because of a water pump housing issue. Still golden. I also have a firend here in CO that got an engine from them, with no issues. Maybe we were lucky, maybe not.
