I would almost bet that this 20b will have a little
trouble staying cool, I have a bigger rad and have heat
problems.

The best part of his install, and what makes it unique is his engine mounts. They made them themselves.

With too big of a radiator you start to lose cooling efficiency. Once it gets too think, the air cannot flow through it nearly as well, and therefore cannot cool nearly as effectivley. Maybe you need a smaller radiator?

You can run a 3 rotor with a haltech (e6k). You just can't run split timing.
The only standalone that can do split timing on a 20b (without using multiple computers) is the new Haltech E11

now is correct that radiator is too small, it fits nice though, and theres not way it will run 10's on the stock turbos

It looks like a good radiator to me. It's not the size, it's the efficiency. Also, it looks like they retained the 20B water pump, which was designed to cool a 2-liter turbocharged rotary.

Lots of us made the mounts ourselves (or our friends made them, like in my case, lol). What impresses me is that they relocated the steering rack to fit the engine under the NA hood. Now THAT takes some dedication to the sleeper concept.

Hehehe, exactly my thoughts on that 4" thick intercooler. I also don't understand why they bothered with a 95 FD transmission which is a pain to fit on that car, but has the same strength as a TII transmission, and I believe even has the same gear ratios.

Most of the new EMS products this year can run a split on the 20B. This includes the flagship units from Haltech, Microtech, Motec, Wolf, and possibly some others that I don't know about yet. You dang newbies get all the goods.

okay well....I thought you needed split timing to run the 3 rotor properly....I buddy of mine has a 3 rotor in his 3rd gen and he is using the microtech, I think I've also heard that E11 won't do it either, well it says it will but then it only has programming for the 13bt, and the 3rd gen 13b.....

Pettit's Banzai did 11.4, so it makes sense to me that high 10's would be possible with nitrous. Traction may be another story, though.

Also, I don't think the CFDF clutches have performed very well on drag FD's in the 500hp range. Please correct me if I am wrong.

The split timing is primarily for emissions, and from what I understand the high-boost drag racers also dial in some split. None of the Mazda-sponsored road race 3-rotors or 4-rotors use a timing split. Also, the factory 20B-REW ECU uses both load and rpm to determine the split, so if you consider that running "properly", then I don't know of any standalone EMS able to do that.

The E11 is too new at this point to fully evaluate, but I think it's a good assumption that it will run split timing if The Hitman thinks it will.

BTW, I forgot to add the TEC3 to the list of brand new EMS products which run split timing. Sorry about that.

OK Mr. Wolf
You should've waited a bit longer
How is your 20b anyways? I haven't seen anything about it in a while.

I'm sending it off for an upgrade in a few days. That's one of the advantages of buying a good product.

My comment was in respect to the fact that some of us have spent years trying to figure out the 20B conversion, and nowadays you can get an EMS that runs split timing, a 20B exhaust flange, 20B FC engine mounts, and all kinds of things that were not available a short time ago.

I've been concentrating on the 1Gen until the economy recovers. The stock market paid for a lot of my project, but now I'm buying, not selling, so funding is a bit tight. Also, the aviation industry is in the dumps right now. At least I'm still better off than the computer networking folks. Um, I think.

I was sure 20B split could be controlled with an E6K and an IG5.

I think you are right, but still, an E6k by itself can't control a 20B with split timing.

The thing that really scares me on this swap? They used an NA GTU! The one picture still showed the single piston front brakes...that also means non vented rear disks. I guess they don't want to stop that "10 second sleeper"

Damm!
I can see why 20B conversions cost some serious $$$. A lot of work involved.

As far as the Wolf is concerned. Yeah, I should have bought a Haltech...

I don't believe they have a 3 rotor dizzy. Or a carb for that matter.

Looks like it will be nose heavy. Won' t that 20B mess up the 50/50 balance of the RX-7? Won't it kill the handling?
