Hey guys my name is Jeremy and i just bought my 13b twin turbo JDM motor for my 1987 mazda rx-7. My buddy has had the car for a llittle while now and he dropped 10k into the car. bought a new single turbo 13b motor and drove it for a while but due to shipping misscomunication he blew the motor and decided to buy a rx-8. now i have the car and i decided to go with the 13b twin. just bought the motor and ive heard it will mount right up but not really sure. it already has the single turbo motor and I thought that the only differance between the single and twin is the extra turbo and piping and wireing but thats all. What info can u guys give me.

I really need to know where I can get mounts to buy and make the job alot easier I already have my ecu and all that from the 13b single T swap. but I cant find mounts to buy for it.

I make and sell the mounts. Click the banner in my sig to order. Theres more info on the swap here.

Yep i orderedc mine today how long does it usually take to get them. I found your post before I could figure out how to check on my post haha. do u think you could give me a list of things I might need. I have most of it I belive. but if I had a list I could check off the stuff I already have and then I can see if you or anyone knows where I can get it. I would really appreciate it. Im not very good with the rotory I was only a little kid when I had the one that my dad gave to me and that was a 1st gen carberated so it was way diff than what im dealing with now.

The turnaround time is typically 1 week. I should be able to get yours done this weekend and shipped out early next week.



As for the details of the swap, it really depends on what all you are doing. At a minimum, you will need to address the exhaust, intake, intercooler, cooling system, oil cooler, and electronics. How you deal with each really depends on your setup though. Oil and coolant should be easy, just lines and a radiator sized for the expected HP. Exhaust and intake are really just a matter of running a little custom piping. Intercooler and electronics will be pretty similar to doing it for the 13BT.



I hate to be so general, but there are so many options that I just cant be any more specific. As you start getting things in place it will be apparent what you need.

I Have a single turbo and I have a frontmount intercooler and my friend had it running but like I was sayn my friend blew it up haha. so I didnt think it would be very hard to swap for the TII. My biggest issue will be my wireing u wouldnt be able to send me a wireing diagram or anything would you, I think Ive figured out the rest. I just need to figure out the wireing.

make sure if you slap that single on there you get it tuned for that setup. running the rotary engine lean is a quick way to another blown engine

woah, just noticed you're in indiana too lol. i know it'll be a hell of a drive for you but sometime you should visit Chris's shop in pierceton. him and his wife run it and they always have some wicked 7's in the garage they're working on

Yeah sweet man I'm puttin the twins in it though it already has the single and we had it tuned I have a venum ecu that's chipped the reason it blew was when they shipped me the motor they didn't say they put a mettle plate behind the turbo and the back pressure went into the motor

I haven't gotten my mounts yet did something happen.

Check your messages, Ive sent you a couple of emails as well as a PM.

Yeah sorry man I didn't see the email until after I sent that message haha I have the mounts and I'm going to put them in today

I'm going to sell my front mount and buy a bigger one do u have any sugestions on what kind to get

Ive got a Greddy clone IC Im looking to get rid of. The core is 18" wide by 12" tall and 3" thick. The inlet/outlets are 3". Theres no piping, just the intercooler. $100 plus shipping, PM me if youre interested.

I'd also sent you a PM a bit ago. You should get a hold of me. I'm local, know the car, and have some RX-7 experience.

Yeah sorry man Ive been working going to school and working on my car havent had time to get on here in a bit.
