My NA 20B in FD project...

So I'm going to see how this goes... I'm not typically one for a build thread. That is mainly because I forget to post updates as they happen and/or forget to take pics to show progress... not to mention delays in projects that I know annoy people trying to follow along with a build thread... the delays end up annoying me too and i'm the one doing my projects!!!

But, I'm going to see how this works out for me this time... hopefully this will help me keep moving forward on the project.

So... at DGRR 2013 I had the crazy idea that I would do a 20B! I already have a v8 FD... I've had it for years and I'm known for having it... I've also had a rotary FD and a handful of rotary FCs... so my original idea was to do a 20B project over the next year, keeping it as quiet as i could and then just show up with it at DGRR 2014... well, that plan didn't work out... and the other deadlines i tried to set for myself didn't work out either... so yeah, glad i didn't start a build thread back then...

Anyway... I didn't just buy a 20B and then it sit... since I got it, I slowly started collecting parts, thinking about the project, collecting more parts... changed my mind about which car would get the engine, etc...

So the idea:
- NA 20B with triple throttle bodies in an FD

Parts list:
- A Series 20B
- S5 NA Rotors (balanced by Mandeville)
- Street port
- triple throttle body intake w/ air box (purchased from other member)
- Defined Autoworks header
- Defined 20B mounts
- Electric water pump (due to the intake I purchased from member in Australia)
- Haltech PS2000
- PXL Wide band
- Rebuild by Liberty FD transmission
- 4.3 gear final drive LSD
- 6x LSx coils
- Sakebomb 25 row dual oil coolers
- aluminum radiator

I picked up the 20B through AllRotor93, sourced the NA rotor from an old s5 engine of mine and 1 from RotaryResurrection... Intake from Alister... Header from Justin (in Canada)...

A local builder helped me tear down the 20B several months back and confirmed that all parts were in good/great condition and it looked like a fairly low mileage engine.

Now... after several months of dragging my feet and letting other things get in the way, I'm hoping to hear back from the builder about meeting up with him within the next few days to reassemble my engine, Saturday I go and look at a roller...

And I know people like pictures... so here are a few... in my Google+ account:

UPDATE!!! Got the engine put back together today with the help of the local builder...

now the next things on the to-do list:
  • get the roller here to the house
  • get the header ceramic coated
  • mate the trans to the engine

here is a teaser from today... I only ended up taking 5 pics total... if you've seen one engine going together, you've seen them all...





the other were added to the album... click me to see more pic!!!

so, i picked up the car this weekend... and threw some body parts on it to test fit. looks like I need to play with the front support a little, might be bent down a little bit... not completely sure. The roller does need some body work and repair on the rear quarter panel... so just have to talk to the body guy when the time comes...

I got the roller from a good friend (and parts seller) Jim (tomsn16) in Cleveland TN... if he has a part you need, do not hesitate to do business with him. Every time I've gotten parts, communication is great, quality is spot on and price is fair. He's a great seller!!!

I also was able to bolt on my side-mount alt bracket. hopefully get the engine dressed up a little more this week when some I have some block-off plates and few gaskets show up.

Main goals for me right now are to finish up dressing the engine, get my header ceramic coated, depower the steering rack, and hopefully having the drive train set in the car within the month. I hope for good weather this week so I can get the 4.30 diff installed and axles.

My RE-A AW7 wheels showed up, I will eventually need to get them rebarrelled so they are wider.

now for a little colorfulness...




Total of 8 pics added to the album... I plan to get some more pics over the week as I continue to dress up the engine.

And just some notes for later... the oil port on the front cover of the 20B is an M16 (like the FC) NOT M18 like the FD front cover.

just a small update... I did a little test fitting of the engine + trans with the mounts and oil pan...
  • Mounts: Defined Auto brackets + 2.6" Xcessive Poly lower mounts
  • Xcessive 20B oil pan kit
I'm not comfortable with the angle of the engine + trans and the oil pan rests on the steering rack. The back of the trans is about 1'' or more lower than stock (estimate is based on trying to mount the Banzai Trans brace). Also, with the height of the engine, my front strut bar doesn't clear my #1 trumpet, but the trumpet does clear under the hood about the thickness of my index finger. So now i'm considering my options to allow me to tilt the engine more, lowering the front while raising the back of the trans... yes, i'm toying with the idea of a dry sump system...

I've since pulled it all back out and stripped down the bay as much as I can in prep for getting it painted.

Cliff notes:
New Super Pro bushings front and rear (ordered from J-Auto, who is a GREAT guy to buy from!!!)
New OEM Pillow ***** (also ordered from Juan at J-Auto)
J-Auto Trailing arms and toe links
Suspension back on the car with the 4.3 diff installed as well... (hopefully by the end of the weekend)

well, after some delays and life happening...

i didn't originally plan to do this in the build but after checking out the suspension and swapping the '94/'95 subframe that was on my shell into my other FD, I ended up deciding to do new bushings all around, including the pillow *****.

The diff already had super pro bushings, which i only realized after i had ordered my first set from J-Auto (1st set was for my v8 fd). So about 2 wks after that order, I ordered another set of super pro's from Juan, along with his new rear trailing arms and toe links. And from my misreading his website the first time I ordered parts, I ended up with a set of OEM pillow ***** w/ new dust covers.

Today I got all the old bushings pressed out and tomorrow I plan to install all the new ones and see about getting the suspension back on the car along with the 4.3 diff installed.

With this out of the way, i can motivate myself to clean and paint my depowered steering rack, re-assemble it and get back to test fitting the engine again, this time with the OEM oil pan.

Side note: I have a Xcessive 20B oil pan on the car right now but with the defined auto motor mounts, the front "hump" of the oil pan rests on the steering rack, raising the front of the engine and made it impossible to get the back of the transmission high enough to bolt in my banzai transmission mount as well as greatly effected the angle of the driveshaft.

so, this past weekend I was able to get the engine test fit again with the modified subframe, depowered steering rack, stock 20B oil pan (with banzai racing oil ban brace), exhaust, trans, and intake setup.

now everything clears a stock hood... without the fancy air box... so i'm running open trumpets and need to figure out filters for them. At this time, the car is stilling with a full drive train except for drive shaft and powerplant frame.

one thing to note are that the header barely touches the subframe so when i pull the engine off and before the car is sent off to get the bay painted, I'll need to do a little massaging of this area. need to just notch it to clear more.

otherwise, i'm happy with the clearance the steering rack has below the engine... and if i wanted about another 1/5'' of clearance from the hood, I could get some 2.4'' tall engine mounts (instead of the 2.6'' I have now) And dropping the engine lower would definitely require me notching for the header on the subframe. I'm also having to look at other options if i want to run a front strut tower bar, the one that came with the car doesn't clear the trumpets.

as before, next steps:
  • engine bay painted
  • header coated
  • massage/notch subframe for header

as for being complete to where I'm ready to share it and show it off to folks, I doubt it... but I would definitely love for it to be running and just waiting for final paint by DGRR... but I'm sure that I'll still be up on the area that weekend, just may not be driving the 20B car in the currently multi-color trim!

** please forgive the rotation of some picture...

OK, so time for some updates... after the last cars and coffee (Aug 20th) I decided it was time to make the big progress on the project. Checked and double checked everything and have convinced myself to try to get the car running by Oct 7.

As for the headers, the collected slid on as it did before, so I didn't have to remove any of the coating... so now the pictures of the progress and then next steps and comments at the end.

In the parts collecting, got another '94/'95 rear subframe


Other parts collected and stashed until I decided to make this happen


Here was me getting ready with the 20B stuff - playing with getting the drivetrain oriented how it would line up in the car




Red car went in, by the end of the weekend the Ford 8.8 was out of the car, by Monday the trans was out and I believe it was thursday we pulled the v8.
rebuilt stock FD diff with low mileage torsen unit and 4.3 gear compared to the 8.8 with 4.1 gear


T56 and 8.8


Empty v8 subframe


Out with the old... end of one chapter...


Cleaned up the fancy quick steer rack..


Mounting engine and header onto subframe to be lifted into the car


had to pull off the header to put the trans on... and the fancy new FFE primary fuel rail...


and since too many pics in first attempt... we have to make 2 replies!

and within 4 days, car was no longer engineless


test fit of radiator and fans...


and after a long evening my helper was tired...


Sakebomb Garage 25-row dual oil coolers installed



So now the problem areas... need to modify the lower outlet of the radiator - will be rerouting it along the bottom so i can mount my electric water pump as well


Oil thermostat hits V-belt with the current alternator bracket, I have another on the way that will lift the alternator at least an 1" and should clear everything so I can make a mounting bracket for the oil thermo...


Next was the coil brackets:


little close so I flipped one and now have clearance for boots

Now test fit of intake with coils



New injectors properly seated in secondary ports now...




And other few little things...
high torque started using an rx8 starter, just swapped the FD front housing onto the rx8 working bits of the starter. Clutch hydraulics are swapped back to stock units and I'm waiting on a new strut tower bar that is scheduled to arrive tomorrow.

I have to get some more fittings for fuel lines, create the lines for block to radiator to water pump... and wire it up.... oh, an get it realigned...
