Ok, I just got off the phone with one of those japanese engine places and they said they had some 13B's for sale...
They apperently had some 13BT's which he said were single turbos out of most likely late 80's RX-7's....they also had a 13BTT which he said was a twin turbo out of a cosmo...
Now the 13BT's apparently didn't have their electronics and I'd need to buy/find a computer for the thing...the 13BTT was apparently pretty much complete, he wanted ~$750 for the 13BT and ~1100 for the 13BTT...are these reasonable prices?
The idea here is to replace the 12A in my 79 RX-7, which one do you guys think would be better for the task? I've never read anything about the 13BTT and I figure someone here might know something, are they any good? Do they make much power? Would they be a royal pain in the *** to transplate? Are the engines the same thing once the turbos come off? or are there actuall differences in the castings?
I would like to know where did you get that price quote from what importer, the best I have seen a 13BTT or correctly named 13BREW from the cosmo is about 1595 from FC3s.com very interested. where are they located are they in japan and does that price include shipping too??
13BTT did come in the Cosmo.The JC.The same one fitted in Japan with the 20B.Mostly all Autos.They have huge intake runners and ports compared to FD.They are good value.Have you guys heard of Microtech Engine Managment.Australian.With the rates the way they are I recon one could be had for 800US.They are as good as Haltech but fully tunable without a laptop.
I'm pretty sure that in japan they had badged the twin turbo Cosmo or 3rd GEN FD motor with a REW designating twin turbo , RE for rotary engine and the W standing for twin turbo, speaking of Microtech EMS I was looking into getting either the Haltech, SDS or the Microtech what have you guys tried? I know the Microtech is well supported in australia and the haltech has a large following around the world and SDS seems to be a verycost effective EMS too, wow you say $800 for the Microtech if you can manage that then I'm game maybe we can get a group buy going for any of these Enigine management system so whe can all bebfit from the price cut
I run a Microtech MTX8. They are very capable low cost ems.I run a 13B turbo and find they are a treat to start up after installation as they already come with a base map so you can start the car straight away.Fine tuning can then be done on the dyno.The new laptop version also has additional pulse width option for air con and cold start. They also have a 4 map memory feature for different fuels.ie low boost on pump fuel or high boost on race fuel.They are fine tuning a boost controller option aswell and have shown good caractaristics for eliminating boost spike.The laptop version does not need a laptop to tune as this can be done with the handset which is a usefull tool for datalogging.max air temp, max water temps,max revs, max boost. injector cycle. They also come supplied with 4 bosch coils or you can run the original ignitors with the MT8.We make 360rwh on 15psi.
I dunno either... the twin turbo 13B used in the Cosmo was the 13B-RE and the twin turbo used in the RX-7 was/is the 13B-REW. Minor differences between the two, but they're different. There was no "13BTT".
(the W is apparently shorthand for "double"... which I don't understand, who calls an engine a double turbo? Twin turbo, yeah... dual turbo, maybe... double turbo? )
I would like to know where you found those prices for those engines. i have not heard of such a deal. if you would please email me at firstname.lastname@example.org i would be very appriciative.
I'm also interested in getting one of these Cosmo engines. Maybe we can organize a group buy with these folks? errrrr, so did we ever figure out the correct name for this engine? What kind of power outputs does it have compared to the US rotaries? Thanks for the help guys.
