r/8thGenSI

is this safe?

i just bought an 8th gen si and it came with a dc sports intake, catless headers and a yonaka catback. i just read online that this is unsafe for my engine without a tune, should i be driving it lightly right now? ive been hitting vtec for the past few weeks.

75,000mi

She just hit 75,000 miles. Hopefully she sticks with me for another 200k.

Any tips on keeping this K20 alive and kicking?

I have spark plugs and air filter, and already changed the transmission fluid.

I’ve heard a few people recommend valve adjustments around this time. Any input is appreciated, thanks.

Hondata download button not working

I tried downloading hondata onto my laptop to flash a new tune since I got my cold air intake but every time I click the download button on the website, I’ve tried my laptop, my main gaming pc, and a MacBook and nothing works even disabling browser security.

Is anyone else having this problem? I can feel the car running too lean and I don’t want to cause engine damage.

Edit: I guess all I had to do was just log in

Finally got everything with the engine and trans all done and am moving on to cosmetics

It’s been a while since I posted my dyno charts and stuff after my rebuild and figured I’d update you guys on the project.

After I posted my dyno charts I found a tiny oil leak coming from my vtec solenoid and omg bro… what a pain! The oil would leak down and get on the belt and the belt would sling it everywhere so it was hard af to find but I finally got it

And btw oil will destroy your belt in a few hundred miles if you ain’t know lol.

But the engine is leak free.. running strong af and now I’m starting on my cosmetics.

Oh .. my ac comp took a dump and spread the black sludge of death all through the system so I’ve been flushing g my evaporator and lines. Replaced the condenser, dryer, and compressor.
