Banzai Racing 20B GT42RS 93 FD
This is one of our shop cars that we work on when we get a chance. A year ago I decided that is was time for a 20B. The core engine arrived on 8-27-08, yesterday (8-26-09) we fired it up for the first time. We did not plan it this way, it just happened.
So on to the good stuff. We were lucky enough to source a D series engine (D303)for the project. We rebuilt the engine with an aggressive streetport. It required two new housings so we opted for two brand new 20B housings, just to keep the numbering correct. Exhaust sleeves have all been swapped for FD's. The Exedy twin disc clutch was used to get the power to the trans. http://www.banzai-racing.com/20B/Eng..._on_pallet.JPG Complete 20B breakdown: http://www.banzai-racing.com/20B_engine_breakdown.htm http://www.banzai-racing.com/20B/Eng...uild_front.jpg http://www.banzai-racing.com/20B/Eng...ni_lg-blk3.jpg Complete Rebuild: http://www.banzai-racing.com/20B_rebuild.htm We decided it was a perfect time to strip the engine bay and have it repainted. So we delayed the project by a few weeks so that this could be done: http://www.banzai-racing.com/20B/E-B...ebay_after.jpg Engine bay shots through the project: http://www.banzai-racing.com/20B_eng...transition.htm For the turbo we went with the Garrett GT42RS (102mm) with the Tial 1.01 v-band turbine housing. We also used the Tial 60mm wastegate. http://www.banzai-racing.com/20B/Par...2RS_turbo3.jpg More pics of turbo, wastegate, manifold, and downpipe: http://www.banzai-racing.com/20B_installation3.htm Engine management is the Microtech LT-16 (one of the very first in the country when we bought it). We designed a custom adapter harness to make it plug and play with the hybrid Cosmo/FD engine harness that we made. This made it much simpler to keep the speedo, wipers, fan relays, etc all functioning normally. Honestly when looking in the engine bay it looks like there is a OEM engine harness, that is because it is. http://www.banzai-racing.com/20B/Par...er_harness.jpg There was lots and lots of custom piping, bracketry, etc. to make for the project. We made a custom Greddy elbow to mate to the 20B TB. We used a custom mounted Koyo N-flow and dual 25 row oil coolers to keep the fluids cool. Every vacuum, fuel, oil coolant line is all ss braided. http://www.banzai-racing.com/20B/Par..._20b_elbow.jpg Now we get to start driving it and putting some break in miles on it. The initial short trips have already been a blast, the car spins the tires with any blip of the throttle. http://www.banzai-racing.com/20B/20B_ebay_08-26-09.jpg The entire year long project can be seen on our website : http://www.banzai-racing.com/20B_installation3.htm Video of the car running: Maiden voyage http://www.banzai-racing.com/20B/ban...den_voyage.mpg Video of exhaust: Still burning off lots of crap http://www.banzai-racing.com/20B/ban...aust_sound.MPG |
Wow. Looks great. I just love how the 20B looks snuggled into an FD chassis. Great work as usual!!
|
just amazing!!! you guys do awesome work congrats!
|
WOW very cool. Im glad you repainted the engine bay to. That motor deserves a clean home.
|
wow! that is so nice....I wish I had the patients for a 20b project and my pockets were deep enough for a build like this.
|
Awesome Work.. You guys Rock...
|
Unbelievable. Best conversion I have seen yet. Looks factory..
|
A few questions.. are you using a undertray and what subframe are you using. Also did you make the turbo manifold? Any pics of it?
|
Can someone hand me a towel... I just came.
|
It would look better if it had A/C and power steering!
NO I'm just joking That car is BAS ASS!!! |

http://www.banzai-racing.com/20B/20B...w_08-25-09.jpg We used the Hinson subframe, but we had it e-coated for durability, also installed a de-powered steering rack from Maval http://www.banzai-racing.com/20B/Eng..._installed.jpg We designed the manifold, using the RB flange and then had it Jet-Hot ceramic coated. http://www.banzai-racing.com/20B/Par...installed1.jpg There are pictures of everything on our site. |
If my engine ever blows...I'm sending it to you :D
Awesome work :icon_tup: |
That is absolutely beautiful work. Amazing that it can look so cleanly done, without a mess of wires and vacuum lines going everywhere.
Extremely impressive work! |
Thanks for all the compliments. The goal was to make it as "factory" looking as possible, so that someone that doesn't know RX7's wouldn't know that this wasn't the original engine. Obviosly it is a little more shiny.
|
Very nice work.....
|
Here are the side views of the engine bay. All nipples on the UIM and LIM were removed, tapped and plugged or a fitting installed.
..and for those tht have asked via PM, it idles at a smooth 900rpm and is currently pulling 16" vacuum http://www.banzai-racing.com/20B/20B...e_08-26-09.jpg http://www.banzai-racing.com/20B/20B...e_08-26-09.jpg |
That is beautiful. Love the fresh paint in the 'bay, looks like it's still wet :) Looks kind of funny, the shock tower nuts are painted too :tonque: What are you expecting for power/torque on this thing? Running pump fuel? Water injection? Please post your dyno chart when you get it!
|
I am making a custom strut tower bar, so those nuts will not be there much longer, no need to remove them until the bar is done.
Yes it is running pump gas, we will see what it makes when the engine has enough break-in miles. I don't ever make predictions on power. I will tune it to 15psi first and see what it puts down, then think about installing AI. Our 91 vert, the little sister to this has the Cosmo 13b-re with a GT35R it makes 435rwhp @15psi (pump fuel) on a Mustang Dyno. This should make more then that :) |
holy bajeebus that's sweet.
|
I'm gonna have to show people this thread when they ask who built my engine, this is truly impressive. I'm anxious to see what it's capable of at 15psi alone.
|
Very nice work, probably the nicest 20b engine bay I've seen.
|
That is one hell of an engine bay, that's the outcome when we take our time to get project done, do it right the first time, it is truely a piece of art.
Khris |
good job. wish i had deeeeeeeppppp pockets:(
|
:bowdown:
If I am ever ready to do a 20B, I will be getting it done by you guys. Awsome work:icon_tup: |
So, I take it there's no air filter in the plans? Nice job BTW. Clean ass install! It appears to be about 6 inches further forward that other installs I've seen. Is that true or just an optical illusion??
|
So the FD water pump housing mates to the front plate without any interference? I may just end up changing over from the TII housing on my 13B-RE to the FD if so.
|
That engine bay IS a work of art. I want one. Excellent job.
|
nice build up!! just curious what sway bar mounts are they?

I would just like to thank Chris and Elaine for letting me be their when they started the engine for the first time on Wednesdays. I have been watching this build sense the day it started and to be there when it started was just awesome. Chris was very confident that it would start first try, but I had some worries that something little thing would go wrong. Boy was I wrong first try it just roared to life and just after a few minutes of tuning it was purring like a kitten. I have a video of the whole thing I am sending to Elaine to post.
I’ve said it before and I will say it again, Chris does great work. His attention to detail and never cutting corner shows in all his work and this build is above and beyond his already high quality. A couple of people already posted that is looks factory and is it does. Every part, wire, nut and bolt look like it’s supposed to be there. Hats off too a great build. I was lucky to be the first to get a ride in the car and can’t wait to get a ride after its tuned. Joe P.S. Ryan(theRJpackage), HAHA I got a ride in it before you did!!! Hope you like the pic :lol: |
at 15 lbs this should probably do near to 550 at the wheels depending on the dyno. Rotorsports Racing in NC had a 3 rotor that did a little over 500 at 13 lbs I think. Or maybe it was 11.
Also, what is the advantage of the D series 20B's ? Stronger casting, better eshaft? Are they later production or something? |
Arghx- there is a lot more to making power then just having a 3 rotor. Tuning makes a huge difference obviously, but turbo sizing, manifold design, IC, ignition, everything plays a role. So comparing what this one will put down with a 20B that is in NC is not very realistic.
D series is the last run, there are rumors of an E series but I don't know if anyone has actually seen one. They started with no letter, just numbers XXX, then there was A.B.C, and DXXX. The D series engine incorporated all the lated updates from Mazda. ^I see Gordon beat me to it There are two videos on the bottom of my very first post of the car running. We will post up the first turn of the ignition video when Joe sends it to us. |
Chris, very impressive. I've always known you guys do great work, one thing that stands out is the *cleanliness* of the build.
I do see one major problem in your future though....... TRACTION :lol: Please consider bringing the car out to the Carlisi event next August, we'd love to have ya :) |
The video is the mail to Elaine already, I could not Email it because of the size. I also think Elaine may want to do a little editing to remove all the “HOLY S**T, OOH F***K” and thing like that and make it PG rated. In all the excitement we forgot to watch the language, but came you blame us.

are you using the factory 20B crank angle sensor?
also, The A and B series had some problems with the housings |

I have always had a bit of a traction issue as it was, but I do agree that the tire budget will be multiplied by a significant factor. We will consider driving out for next years event, we are just always so busy at the shop, it is hard to get away

Very clean build, great job!
Dan |
Now that is the definition of sexy right there. Phenomenal job!
|
It's worth saying again just how great of a job Chris and Elaine do......clearly seen thru this build. I have been checking their site almost thru the entire build. They have a realy nice log of it all.
The end result looks awesome. Cant wait to see some dyno numbers. |
How much would it cost if someone if they paid you to do this to their car?
|
I've never heard of the RS. What makes it different from the R?

Oops, that should have been GT4202R
|
Beautiful work. Not that I wouldn't want to own one, but I think that being a part of a project like this, and having a hand in on the build would be awesome as well. Wish I lived close enough to a shop to have that chance.
|
Amazing - that's one clean install!
|
I drooled copious amounts of saliva all over my keyboard.
Very clean. Excellent work. Is this a shop car or a customer car? |
This is one of our shop cars.
|
I wonder when you get say 14-16 PSi?
