I picked up an FD chassis last June. I have wanted to do this swap for a few years now but could never pull the trigger and actually buy one. The car is a full street car, air conditioning, power steering, etc. I am using the RX-7 tranmsission with a B2600 bellhousing. We made an adapter plate to fit the Narrowblock 4G63 to the Mazda Bellhousing. I also had to mod the subframe and drop the steering rack to fit the motor. I used the Samberg bumpsteer kit and modified it since I needed to drop the tie rods a bit lower. Just about everything was fabricated/built in house including paint. The car is a blast to drive as it makes 520whp on 93 octane. It dead hooks 3rd gear and slightly spins 2nd gear with 275/40/17 regular Nitto NT05's thanks to boost by gear and traction control via the AEM series 2. With a full tank of gas and me in it the car weighs 2890lbs. This is the setup:
-6bolt 4G63 bottom end
-CP 9:1 pistons
-Magnus Aluminum Rods
-O-ringed Block
-ACL Race Bearings
-Mild Port 1G head
-Supertech 1mm valves
-Kelford 272 cams
-Magnus Cast Intake
-Either Precision 6266
-Custom Radiator
-Custom Exhaust manifold
-Custom 3" Exhaust
-Custom FMIC
-Custom IC Pipes
-Tial BOV and WG
-Custom Exedy Triple disc Clutch
-Walbro 400 intank pump
-Magnus fuel rail
-Aeromotive FPR
-AEM EMS V2 Honda box with custom wiring harness
-Braided AN line on everything including the power steering and A/C

Looks awesome man. Really really good work.
-
Have you ever considered running E85? I know 6262 evo's are making 600+ with it. Build looks good - I don't even want to know how much those rods cost.

I thought about it but its not regularly available by me. If more stations start carying it then I will think about it. We made 520whp@26psi and there is still another 5-6 psi in it on pump gas alone if I really felt like making more power. Since I am new to the car I am going to keep it at this power level for a little while before I turn up the boost. I expect it to make 550-580whp with the boost up on straight pump gas. On E85/race gas 6266 powered 4G63 will make between 730-800whp. I got my rods as part of a trade for some other parts I had but if I had to buy them new they are around $600-$700. I built alot of this car with parts I had leftover from my old car or other parts that I had put away in case I ever decided to build another car.

Props to you for being original....looks like a very clean setup. I love unique rides, and I think yours is easily classified as a unique ride. :cheers:
-
Amazing. I love it!!!!! 4g63's are tough motors man!

unique build, i like it! and i LOVE that color. looks perfect on an FD.
-
Looks nice. 4G63 can certainly make some horsepower. Good work!
-
Thanks guys. I can't say that I'm the first to do it. There are three other cars with the swap. One is a full race car with an auto, the second was overseas, and the last one isn't running yet. I've been a 4G63 guy for a long time and have loved the FD since it first came out so putting my favorite motor with my favorite car was an easy choice. :D I was shocked to see how light the car was. I am hoping with the Enkies on and less then half a tank of gas I might come in under 2800lbs with me in it. I will put it back on the scales when my rims get here. The color of the car is Carbon Grey Metallic from the Porsche Panamera
-
PHUUUUCK. YES.
Stellar job man!
-
sweet build. I love it
-
2 thumbs up. Looks like a very high quality build!
-
The "race car" is English Racings FD correct?
Your car looks fantastic! Love that color.

How much does an engine + transmission combo like yours goes for? I am curious.

I used the RX7 trans that came with the car and made an adapter plate. As for the motor, you can pick them up from a junkyard for $500-$700. The stock motors will handle 450-550whp without an issue. Anything over that and you need rods/pistons. You can get away with just putting cams and valve springs/retainers in the head. If you do the work yourself you can have a pretty stout bottom end for $2300-$3000.

Ok thanks. I want a light tube chassis 4 banger in the future, and this motor is def a candidate. i used to have a 420A lol with a rigged up turbo kit - just after the first Fast and Furious lol.
-
cool to see something different, nice work!

Looks fun, ever take it ot the track? Those are some mighty expensive parts for 520whp, plan on turning it up? :poke: My daily driven talon just trapped 124 the other weekend. Amazing little motors for sure.

Seen you made your way over here Bean.

124mph is cute. My daily driven Talon was doing that 12yrs ago. :poke: :D I dont plan on going to the track until the end of the year. Still have to make a rear diff brace and a trans brace for it. Once I stop being lazy and fix the knock sensor I will turn it up on straight pump gas and leave it at 560-600whp. I will consider E85 if it becomes readily available around here. When I do take it to the track it will be exactly how I drive it on the street, regualr street tires, pump gas, etc.

Sure did. This is a great site with good info.

Excellent work and a joy to read this post. Do upload more pictures.

Put the car back on the dyno for a retune. The car made 571whp/376ft-lbs on straight pump gas (93 octane). Cant wait for the warm weather to put the power to the ground.

very nice and original build
-
Love the color. :drool:
Nice setup, a local with that turbo made 745whp on a DD, I think that's over 800whp DJ.
Not my choice of motor, but they are stout. Also had a local run 600whp thru his stock bottom end for over a year 10k miles, lots of stock bottom ends trapping 140s in full weight ish cars, not tin cans.
Would love to see this in person. location?

Thanks, its a killer turbo that can make around 800whp on E85 and lots of boost. They make 550-600whp on pump gas pretty easily. I'm in NJ.

Nice car, I like this swap.

Awesome, love the setup! Good luck with the stock rx7 trans, I hope it holds up to your future power goals.

Thanks. From everyone I have talked to about it it will not be an issue for the power I am making. I make 360ft-lbs at peak tq so the stock trans should be able to hold up to that. There are plenty of 500-600whp stock trans RX7's around. I kept the stock trans since it will shift at 9000+ rpm and they are cheap to buy. I picked up a JDM 5 speed for $250 and that is in the car now. I will rebuild the one I have and keep it on the shelf for when this one breaks.

After doing Andrew Brilliant's 2G Eclipse time attack car, I've had HEAPS of respect for these engines. That dyno curve looks great, and having an 'overbuilt' engine is not a terrible thing lol. I love communities (4G63 and LSx among them) where 500whp is scoffed at lol.
-
Is your paint a custom mix color? If not could you tell me what it is.

They are great motors. 550-600whp is really the norm on straight pump gas these days. Its crazy. We just made 918whp on E85 on my buddys Evo VIII with a PTE6766 turbo and a stock computer.. That car made 600whp@18psi. Its a beast on the street. Its got PS, AC, etc.

Hey Bean....how did you center the trans on the adapter plate/flywheel You can't use a dial indicator on the bellhousing like I planned. Did you just let the trans center on the pilot bearing and drill your mounting holes?

My machinist did the adapter plate so I am not sure how he did it. I gave him a block, 6bolt starter plate, and the b2600 bell housing, he took care of the rest.

HAHA! Well it was done in house so it counts. :D From what I remember he drilled a hole in the center and then machined a shaft to mimic the input shaft. Then I put the bell housing in the position I wanted the motor to sit. He drilled the holes from there.
-
I've seen similiar arrangments on other types of adapter plate creations. Little out of my abilities and I don't think I have any local machine shops that good do that. Hell the engine shop I use might not be able to machine off 1/2 from the housing...doubt they could make a dummey input shaft. Do you got a pciture of what your guy created?

I just have a couple questions. How's the tranny holding up to that power? Is your oil pan still a front sump and do you have any pics of the subframe (maybe with the engine in the car for referance)? And about what rpm does the boost start coming on?
I'm building a 4g64 for my FC but I'm using the wideblock with the b2600 bellhousing. I'm still unsure of the turbo I want to run at this point, but I'm not looking for anything over 500hp and I'd like it to spool around 4k (at the most). I also plan on modding the oil pan to make it a rear sump, I'm just curious if I will still have to mod the subframe.
I also wanted to add, very cool build, and I love the color. :drive:

Transmission has been good so far. I have around 4-5k miles on it. Keep the torque low and the transmission will stay happy. I don't have any oil pan pics but I could try to take some the next time its on the lift. Its still a front sump. I had to cut some height off the sump since it sat too low so I made it a bit longer and added a wing to the side for more oil capacity. I also moved the pick up further back then the stock location. I get full boost at 5,000rpm and the car is still making lots of power at the 8700rpm rev limiter. I'm sure it would make power to well over 9k rpm if I raised the rev limiter but there is no need to push it right now. :D
If you only want 500whp then I would go with a GTX30R or HTA3076 in a .82a/r. On a 4g64 spool will be around 4,000rpm and the turbo will make 480-500 on pump gas.

hi, I was looking into your post and this is what I'm about to do. My car is a rx8, I will be using the rx7 tranny and the b2600 housing but for what I have read so far the 87 b2600 housing should be a bolt on to the 4g63 block and the rx7 tranny right? why do you need the adapter plate? Thank you and I will be looking forward for more updates on this built, btw I have been a mechanic for 1g and 2g for 15 years now so that is why I chose the 4g63 block.
-
The b2600 bolts to wideblock 4g63. You need an adapter to bolt it to the narrow block setup. I did the same thing on my FC 4g63 swap. The adapter plate also allowed for the correct pilot bearing spacing.
