Hi guys, i am new in reddit and i created this to ask this question. i would like to know about california BAR legal engine swap for 1991 honda civic.

Are both b18c1 and k20a2 engine swap can be BAR legal?

If i am to do the B series engine swap, how hard it is and how much will it costs?

If i am to do the K series engine swap, how hard it is and how much will it costs?

Is there any shop in california hat can do the engine swap?

Thank you in advance for all the info.

got it for dirt cheap

Hey all (again),

Finally got around to tearing my motors down and I’ve sent the new block off to the machine shop to get resized and prepped to be used. But when I took out my old pistons, I noticed a couple of weird spots around the ringlands and one mildly concerning one. Are these still usable if I bring them to the machine shop too or would I be better off buying new ones? They’re forged and they only sell them in sets of 4 from what I know so I’d really rather not buy them again if I can avoid it for a while at least. Block is not being used anymore, photos are for context of what happened

I replaced all four sensors and cats

I replaced sensors again after getting this diag and still getting the same codes

Front 2 sensors NTK
Rear 2 sensors Denso

Can anyone help please

Had a running 92 eg hatch with k24a2 swap. Running Linkg4x ecu (for all intents and purposes, treat it as a type s exu) and 02-04 rsx type s harness with ktuned conversation harness.

Car would die during WOT pulls, isolated a sensitive “A” connector to the ecu.- when I pushed the connector, the battery voltage would drop.

I bought a new “A” connector, and very patiently transferred each pin (one by one) from the original connector to the new connector. I took many pictures beforehand, and there is nothing obvious that I incorrectly pinned it.- except for the fact that the car won’t start now.

No, fuel pump prime, ecu won’t turn on. But otherwise I have power to accessories (horns, lights etc.)

Pins A2 and A3 correctly show 12 volts when I ground pin E7 (main relay power to ecu), and A4 and A5 correctly show strong grounds. Please help!!!!
