build up of JDM F20B DOHC VTEC

More progress



That's not supposed to be in there!

Dam dude, how did that timing mount threads break like that, was it like an 800hp engine? That piece of metal doesn't look great either. Its gonna take a lot of good work piecing that engine back together. Good luck man.

I just got done with a little engine build of my own and about ready to crank if over. Hope it works out for a newb like me.

I think it broke because the mount only had two bolts in it but my friends dad is gonna weld it back together for me. The metal peice looks to be part of an Allen wrench lucky the screen in the oil pick up stopped it. Everything else looks really good though.
Good luck with your build hope it starts right up!

It did and it runs good but my speed sensor is brokeded. I ordere another for $7 like last time. Seems that everytime I remove my engine it breaks. Must be a Honda thing. even the OEM one I had broke that way. Probably the most important piece for any tuner though is the speed sensor, lol.

So you going to put in in a civic? Good choice. Much better to put a 2.0 in there than a 2.2 or 2.3. It'll be more stable I believe.

Your friends dad knows how to TIG weld? That's cool, wish I had connections like that.

I'd get the balance shaft elimination kit. I did and it was worth every penny.

Good luck with this. Engine work can be some of the most labor intensive and difficult work out there, and its no wonder mechanics get payed so much. I realized that over a year ago.

Yeah I'll be putting this in my civic, I'll be using an h2b kit so I can't utilize the b16 transmission I picked up not long ago. With that kit it uses all the b series stuff so no special axles or expensive mounts are needed.
Yeah 192 hp should be fun in this car, weighs in at 2300 pounds I believe maybe a little less as I've removed some interior pieces

Yeah I planned on getting the balance shaft delete kit and the ks timing belt tensioner
This is my first real engine rebuild, I've taken a few apart but never put it back together so I'm taking it nice and slow, my friends are helping as well so everything should turn out ok. Also doing a lot of research to figure out what parts and pieces I can use from is cars on this engine

If you plan on taking that motor up anywhere near 8k (And with a b16 trans, oh you will I assure you) i'd suggest doing the kaizenspeed kit before slapping it all back together, the upped Oil Pressure and lightening of the rotational assembly will do wonders.

I'd also look into upgrading the Oil Pump, just for the benefit of the doubt seeing as these motors tend to run into starvation issues under load and G forces (Turning, braking, ect--Oil slooshes around in the pan and even a moment without oil can DONE your set up) and a better pump and Pick up can alleviate that.

Looks nice so far, I 220's gonna require some work tho, you doing pistons and headwork?

Yeah I'll be doing the ks balance shaft delete, I actually don't have much of a choice the balance shafts actually hit the frame rail with the h2b setup. Also have to run a shaved crank pulley or a single row whichever I can find.

I will actually be modifying the oil pan and adding a baffle to help with the oil sloshing. The pan and pick up need modified to work with the h2b as the engine normally sits at a 15 degree angle and now it's more straight
This is from my old h22 but shows just what a little low oil pressure will do


For now I just wanna get it in and running, then I'll start collecting parts and see if I can't hit that 220hp mark. Shouldn't need much bottom end work to get that number. Maybe forged rods just to be safe it that's down the road a ways.

That doesn't look good at all. That poor oil pump.


My question is why you wanna put that in a civic and not a cb7
After all this is a 4th gen accord site.


Keep up the work, but don't overlook anything. Be meticulous and this is sure to be a good motor. I'm a bit skeptical as to how you're gonna actually make 220 at the wheels. You're gonna need fuel pump, injectors, a heavy clutch, and a super good tune. Not that I know jack about any of those things lol.

The answer to why a civic and not my accord is because my accord is auto and would be a waste of this fine engine. Had this thread not been started by fatboy1185 I wouldn't really be posting about it but since it's here why not.

It was making 192 at the wheels in fatboys car with bolt ons, 220 is roughly 30 hp. With cams , better intake , quality exhaust manifold and a good tune should get it pretty close. Fuel pump and bigger injectors would be a must. Stock or stage 1 clutch would be more then enough.

Kudos man. Honestly if I had to pick i'd always throw these motors in a civic, the lighter chasis? Power to weight outta this world. The only H-Swapped CB7 I still own is my Stroker (2.7), my other two are J swapped, I feel the day and age of H swapping or building up F-Motors to go into CB7's are done. Out of the box performance of a J-Series motor and relative ease of insertion ontop of the minimal cost those things go for these days...make it well worth it, I have ZERO complaints after getting mine in.

I'll be keeping an eye on this and lemmie know if you need anything, I have a single row pulley and a boat load of H and F Series parts left over for sale, transmissions, all that.

[sonikaccord]

OT: Do the J's physically fit in the cb's bay? Height wise of course.

[c91bse7]

All welded up and ready to be put back together

[fatboy1185]

Oh snap.
