Rx3SP 20B HP Project street car
 

Rene built 20B project street car.

This is the story of a Rx3SP transformed to a 20B monster street car.
This project was started late december to be transplanted from a 13B
to 20B,not only a 20B but a really radical high powered (almost full race)setup for the
street.This project was suppose to stay secret but pictures got out and the demand
was given to see more of this project.I have no choice but to show and tell from
now on.Here hare some pictures of the first stages of the project.There will be more
pictures as the Rx3SP gets closer to the finishing stages.As of this moment the Rx3
project is 75% finish.To top this off this is about the 3rd week from the start of the
project and it is about 75% done.My goal is to finish before the end of this month,
that is starting it and tuning the 20B.

This has been my job as a fabricator for the last 10years,i started working on my cars
and learned from it and now it has been a job applying all i know from racing experience to the costumers.Let me know what you people think, hope i get some good feedback. :)

Here is the 20B engine bone stock when i got it,first picture
Here the engine stripped to the bone,2nd picture.
Here is the engine being before polishing and cleaning.

Here are other picture of the engine put together (monster street port) and Pinned using the stud kit for the 20B.It took about a week to do the engine alone.1st picture

Here is the engine with the polish intake manifold (really good polisher guy)top and bottom polish.2nd picture

Here is the engine from another shot of all the intake part being put together.3rd picture.

Here is the engine with the front cover and pulleys.1st picture

Here is the engine with the custom pan made by me(Rene Jr). 2nd picture

Here is the engine with the 2nd gen dizzy and coils on stand. 3rd picture

Looks like oversised studs?

Just curios, why not all of them?

What do the internals consist of? I'd like to know all of the pertinent details?

very nice work, I hope you have a good roll cage in that thing.

Here is the 20B engine on the Rx3 for the first time. 1st picture

Here is a side view picture of the 20B engine. 2nd picture

Here is a front view of the 20B engine showing the pulleys. 3rd picture

The engine is a B series block, big street port, modified oiling,stock 20B engine
rotors with 2mm ianetti seals.

Microtech LT12 series with individual coils system.All bosh injectors all around.
custom fuel rails primary and secondary.

The 2 stock bolts where left there because they are really big in diameter stock,
and the stock thread vs the oversize thread are really close in diameter so i took
the chance of not cross threading the 20B iron,they are two different threads.

looken great so far

let me extend my kudos to you as well. just gorgeous - both the car and the motor. what turbo do you plan to strap to that thing?

Rx3 project
 

I am going with a nice big turbo,details tomorrow( if i don't get tied up).

oooohhh ... you suck! ;) suspense, eh? i guess you hold all the cards, so i'll stay tuned.

Which stud kit did you use or did you have your own made?

Looking incredible too BTW!!!

looks like a guru stub kit looks the goods though good luck with the build!!!

cheers dave

Rx3 project
 

Yes it is a Guru stud kit,But it takes alot of machine work to make them fit.
On the 20B there are about 5 extra long bolts that go through the entire
engine.You have the replace the stock short bolts.

Here are some more pictures of last saturdays work.

On this picture you can see the custom made intake elbow i reconfigure from the stock piece.1st pic

This one you can see the Gilmer drive pulleys and the super polish alternators.2nd pic

This one is a picture of the front custom made motor mount that i hand fabricated from aluminum,this part is all hand polish (not chrome dipped).3rd pic

Here is a picture of the big frontmount intercooler,3" in and outlets,all bolted down
and snug in that front portion of the nose. 4th pic

This is a closeup of the huge custom front mount from the bottom of the Rx3. 5th pic

:worship:That's complete insanity!!! :bigeyes: Looks to be coming along pretty good. Nice and clean work RENE!

Nice work. I like what you did with the elbow. Are you using the stock air temp sensor? Mind sharing your source for polishing? -Mine is a lazy bastard (me).

Rx3 project
 

Yes i am using the stock air temp i left it on the bottom of the elbow so you can't
see it with all the bling.

There is a shop here local that does all the polishing for me,He polishes like a
a mirror,even on the cracks.

Do you have a resistance-temp curve for it?

Whadda ya gonna use for tires??? If they stick, whaddya gonna use for axles???

Rx3 project
 

We plan to use a ford 9" rear end with big disc brake setup.

The microtech system uses the stock mazda sensor to read the
air/water temp.The air temp sensor has a little wire with a resistor.

Rx3 project
 

Here is an update the Rx3 is 95% finish,just some wiring and that is it!!!
Hope to start up tomorrow,Sat 27.

This project is a new personal record for me, a complete swap with all custom
made parts in just under 4 weeks. :)

It took me 2 months to complete my 20B on my car when i started from nothing.

Awesome Rene. You da man. I guess that means you can do mine in 3 weeks. hehe

So did you get her fired up?
