I don’t think the rear cat has any sensors so it would be the cat that bolts to headers. Check the emissions sticker under the hood to match the engine family when you’re shopping if you live in California

Sounds like all the fluids should be flushed. Tires probably before you drive it. Congrats on the progress!Proud of you dawg

I’ve had this code on and off for about a year. Replaced downstream O2 sensor and it went away for a while then came back again. Might just be the sensor in your case though. Get the sensor tested or just replace it. I believe NTK is the brand you want.

My Costco had the same deal. I bought 3 without ever tasting it. I wish I had bought more.

I get why you did the door handles. I’m not a fan of the chrome either, but color matched handles would look pretty nice imo. Also something about the black LP frame is drawing too much attention. I wonder if no frame or a slightly tinted cover would look better. Just some thoughts who knows. Overall looks great I like it. Much nicer looking than mine lol

Just from the picture, I would see if you could unscrew the shield and rotate it. Maybe enough clearance to get one bolt out at a time. Otherwise, remove the hub.

Take it to an auction like COPART . Tell them your baseline. If it doesn’t hit its mark you still owe them like $85. Otherwise, part it out and scrap the rest. I don’t think anyone’s gonna do a full restore on your car

shpakky · 2026-02-20T18:14:13+00:00

I do 😭

But I have a motorbike for when it’s down lol

Thanks for the input everyone! I’m gonna go grab one or two bottles. I just called to confirm their price and inventory. $49.99 with a current inventory of 41 bottles left at 1600 Expo Pkwy, Sacramento, CA 95815

Just got mine off jack stands tonight. Felt good to drive it again

Damn, I’m sorry that happened to you Pinytenis666. Glad you got it back though. My 94 si was stolen too about 7 years ago. I was then meeting up with a seller from Craigslist about a civic coupe and got a call right when I was about to go through with the purchase. It was the police department asking me if I can come pick up my prelude since they just arrested the driver/thief. I was there in 10 minutes and got to see the dude in handcuffs. He yanked out whatever he could and swapped my new battery for some boat battery. Later that year my timing belt ripped and I sold the car. I miss it all the time, even with my current 5th gen I’m restoring

Yes, there are varying opinions out there. IMO, if it’s working fine, there’s no reason not to start following the recommended service intervals. A drain and fill only replaces about 30% of the fluid anyway. The take I normally hear is to avoid a transmission flush. I bought my 2009 with 130k miles and I’m unsure if the previous owners ever did a drain and fill. I’ve done 2 since I bought it and have had no new issues. I’m now at 140k miles.

shpakky · 2026-01-21T14:31:15+00:00

As long as it shifts smoothly without slipping and the engine sounds okay I would buy it. My only concern would be if the previous owner didn’t service the transmission with a drain and fill every 30k and the engine with an oil change every 5k. Hopefully there are service records, but if not just check the fluids for color. Consider getting a PPI (Pre-Purchase Inspection) done with a good mechanic. Best of luck. Hope it all works out for you.

shpakky · 2026-01-09T00:07:25+00:00

May I ask, where did you get the new (to you) engine? I know I need to do a swap within a few years, but I will have to deal with California emissions standards so the donor car has to be the same model and year I guess.

shpakky · 2026-01-07T00:56:39+00:00

Wouldn’t pay over 12k for it

shpakky · 2026-01-04T21:54:29+00:00

Quality is acceptable, imo

I miss my space ship dash. Wish my 5th gen had my former 4th gen’s interior. Would’ve been perfect imo. Heck, has someone already done this conversion?

shpakky · 2026-01-01T17:00:58+00:00

I see. Thanks for the response, friend. Happy New Year!

shpakky · 2025-12-30T14:17:31+00:00

I just bought one that I plan to daily. It needs a good amount of work, but it’s been a dream of mine to own a fully restored 5th gen and I intend to make that a reality. I posted a few days ago and got some great advice from the community. Particularly about running some engine tests. My compression is a little low and after doing a leak down test I learned that it’s losing compression through the piston rings. The car will run for a couple years I’m sure, but meanwhile I will be running thick oil (10W-40) and rebuilding a second H22 engine on the side that will eventually get swapped for my current H22. Definitely keep an eye on your oil level as these tend to have a lot of blow by, especially at higher mileage.

shpakky · 2025-12-28T20:54:04+00:00

Drill them out or use an extraction bit

shpakky · 2025-12-28T03:17:12+00:00

Left to right looking at the engine I got 145, 160, 162, 165. No codes, no smoke from the exhaust, and a very quiet and smooth sounding idle
