It looks like your MAP sensor is hooked to the IUM and the brake booster is connected to the LIM. Let us know how that works out for you.

By the way, I like that air filter. I'll have to get one like that. Do they come in orange?

All 20Bs were twin turbo, they put out 320 hp stock.

With the extend port, exhaust and ltx12 this engine should be making
around the same hp

A completely stock port 20b engine without the turbos has made 232 rwhp. Hmmm not bad for a 2400 lb car. That's more than what a stock Fd puts down with twins turbos. :D

Two small ones in front of the radiator? Thats my guess!

I'm drooling all over at the thought. I grew up in Puerto Rico
where you see rotaries and mods all over, but I'm yet to see
a 20B in a 1st gen. You guys are wicked, keep it up mate and
thanks for sharing the info. and pictures.

DJAngelicon 07-06-05 02:46 AM

I agree with you on that Grewing in Puerto Rico seeing this cars all over I have never seen a FB with a 20B on a process. I would love to see one in person and hear to see how it sounds like. Anyone in Seattle with that kind of power? :D

TurboSE 07-06-05 02:49 AM

Hmmmm Where's the turbo(s)

d. quinones 07-06-05 02:52 AM

I'm getting crazy ideas... Maybe shipping the car to Puerto Rico for that
kind of modification is not far fetched. I will end up saving tons of money
in labor. Something to think about Latin Heat.

You see what you're doing Rotary20B? Messing with peoples head...

DJAngelicon 07-06-05 02:59 AM

Yea I agree with you d. quinones. I will be having my Wedding up in Puerto Rico around 4-21-07 and while I am down there I will see if I can get in touch with a few Puertorican Rotory machanic and see. My fiance wants to move down there so, if I do end up doing that I will make sure to save alot of money and then take my car down there with me and do a major project on it. ;) Hopefully but I like your thinking attitude. :bigthumb:

d. quinones 07-06-05 03:33 AM

Felicidades!! May your wedding bring many years of happiness for you
and your wife LatinHeat. I've been out of the loop for years in reference to
mechanics in Puerto Rico. But I'll definitely let you know if I find out before
you do. I'm in the military so I won't be able to settle down there for a
while, but I'll be flying there often after I'm done with my deployment.



Note: Apologies to Rotary20B, I know this is kind of out of the subject.
But, as you can see, your thread has messed with 2 puertoricans
who are planning to go back to the island, where things are
caliente.

Let me know if you do (or anyone else)

We are doing up kit for crossmember etc if anyone is interested. Will cut down on the cost of a conversion quite a lot if getting a workshop to do it.

lol no worries

Good to see its got a few of you thinking :)

TurboSE 07-06-05 04:11 AM

so are you driving the car yet?
how is the torque?
That is one of the main reason i wanna do that swap! :D

Jeff20B 07-06-05 04:24 AM

His stock motor mount pads/pedestals are already removed like yours. I'd imagine your kit would be the next step. I'll talk to him in a few days and pass the info on to him.

No worries, it will be a few days before I know costs.

For the person who asked about cooling, I did have a S3 radiator that was record and a twin core. Now have a triple core radiator and am running a single Davies Craig 16" thermo.

The car should be finished in the next week, I will post some videos when it's completed.

The car is being engineered so will be road legal over here, may take another week or so for that.

If I were you I would make at least 5 of those kits. You might not sell them right away but you will sell them.

Rotary20B 07-14-05 03:26 AM

These will be the last pics before it is running, just exhaust to complete now.

Made a few changes, new twin core radiator was replaced with a new triple core, and am running twin 10" fans instead of one large 16".

This pic is of the new radiator, fans & oil cooler setup

I have the same 3 row core radiator but my oil cooler was mounted in front due to lack of space. I mounted my fan on the back side of the rad. I had a 16" sitting around so I used that and shrouded the upper 2" and lower 2" that hangs over the core. I hope the oil cooler doesn't block air flow too much.

Any luck making those motor mount kits? I think my friend's GSL-SE project might need a kit.

He's from the same City. There's a couple of 20B FCs that are almost done too in Brisbane, should be good :)

Check this one out
