Hi guys,
I bought this Dc2 to use on track whist also being a road car. First off, this is the car:

It's a tidy car & i intended to run the B18C for a while. However, it was smoking a bit on WOT, so i replaced the valve stem seals. This didn't fix the smoke, so i had the head rebuilt professionally (new headgasket, skim, new exhaust valves, valve guides etc). After this rebuild (at considerable expense) the car smoked worse than ever.
I was told that this may happen after a head is rebuilt (shows weak piston rings, oil sucked out exhaust port). I looked into a full rebuild but this would easily be 3K. At this point i was sick & tired of dealing with this engine so decided to sell it & go K series. The diehards will hate doing this to a type r but there's only so much a person can take.
The B18C:

And so the build begins:

The Engine:
  • K24a JDM bottom end, weld in baffled sump.
  • K20 Head (RSP), this is the best flowing head of all the K20 engines. Found on FD2 & FN2.
  • K20 Oil pump
  • 50 Degree Cam gear with 40 Degree VTC limiter pin (tactruff).
  • Drag Cartel Drop in cams.
  • Head refresh (stem seals, retainers & keepers, LMAs).
  • RRC Intake Manifold (FD2)
  • K tuned alternator relocation & PS delete ( i will be using electro Hyrdo set up)
  • OEM 410cc RDX Injectors, Walbro 255LPH pump, AEM Regulator, K-Tuned Fuel rail with custom lines.

One of the first steps after the mighty B18c was pulled was to take out the drivers side engine mount bracket. 8mm spot weld drill bit was useful along with hammer & chisel.

Off: Area ground down, filled & painted.

After:

Another Job is fuel line preparation. Need to go from hardline to -AN6 lines. Easier to get these prepped while engine is out.

You do this for both feed & return. Feed is larger diameter so easy to identify.
 
Loved that you tried to keep the b18c but the universe gave you a sign.lol. Look forward to seeing the outcome.
 
Thanks for the comments guys:nice:
Some good progress made today.
Hasport Engine Mounts Arrived!
These are dual height, meaning you can mount a K20 or K24.

Rear mount:

Engine Installed finally, this was installed from the top using an engine crane. Would be alot easier if you have a car lift to drop the car onto the engine.

I'll be moving onto the wiring next.
 
One thing I forgot to mention, if you're using a K24A that was an automatic (alot of them were in Japan), the flywheel bolts are shorter on the automatic. Both will fit but you run the risk of them backing out & destroying your crank/oil pump. Use the manual K20 bolts instead.
Picture for reference:

Now that the engine is in, i did i few small jobs.
Took the engine harness in through the firewall.
Cut the heater hoses to length & made a small heat shield for the plastic valve.

Yeah alot of the flywheel bolts for automatic are a bit short and more time when ever doing a flywheel job, they usually require you change them out just for safety shake
 
Make sure You get the spigot bearing that goes in the middle of the crank and flywheel area as automatics dont come with them also.
Yep, should have said that as-well. Spigot/ pilot bearing came with new clutch with a big warning on the package saying warranty void if bearing not installed. Thanks.

Another job completed. Oil cooler rad installed along with Mocal thermostatic plate.

I love a clean oil cooler setup. Thats brilliant
Thanks man.

Few more small jobs done.
Made a small alu plate to fit in front of shifter. Put a 5v USB charger for my phone in it using existing cigarette wiring.
