1/5/2020 update! pictures on post #5 first page.

Engine blew 5/4/19 and car has been sitting awhile - getting ready to rebuild the engine now. Will be staying NA. parts list below, feel free to add input. Hoping to be around 300whp when finished - was at 221whp/162tq with stock k20a2 full boltons and tune before.

I have 0 experience pulling/rebuilding engines, so this is all new to me. Learning as I go, so hopefully I can inspire someone to show their old rsx some love!

Also turns out - the engine didn't actually blow - when I got it apart I realized a spark plug had just gotten blown apart. the top tip of it was bouncing around in the head as I could tell, and the bottom piece had dropped into the cylinder, found a small bit in the intake manifold and a small piece stuck to the top of the head by the valves.

Already determined/purchased:
k24a4 block honed to 87.5mm, stock sleeves, stock crankshaft
saenz s series rods
wiseco 12.5:1 pistons
4piston rr4 I believe cams
4piston modified k20 oil pump
4piston adjustable cam gears
4piston flywheel bolts
4piston 156 machined k20 head - ferrea valves, 4piston springs/retainers

to be determined to support the engine as it's built:
insane shafts axles/half shaft
ATI crank pulley
moroso baffled oil pan
mishimoto radiator
mishimoto fans/shroud
fuel pump - want to be able to run e85 in the future still researching
injectors - see above
new header/exhaust for k24 bottom end, looking at ktuned 3" option
intake manifold - still researching
intake - researching
mfactory lsd
tsx 6th gear
4.7 final drive

I'm sure I'm forgetting things - still researching as much as I can as I wait for parts to come in to start assembling the block.

Thanks for checking it out! stick around for more progress as we go! I'm hoping to be ready to track season in the spring

slowly building - 07 crew - supreme lurker status :shady:


Originally purchased with 28k mi with only aspec lip kit and uninstalled aspec suspension. Sold the suspension to a member here as I was not ready to modify yet.

Have been through a ton with the car, it stayed very close to stock for a long time. Probably never took good enough care of it, but learned a lot of maintenance basics over the years, enjoyed driving it, etc etc.

Eventually I purchased a DD (09 subaru legacy) and began toying with the RSX. Now she is at about 160k miles, and still going strong! I went to my first track events with SCCA this past fall and was hooked. pictures of track days scattered throughout!

Check back as I piece together any and all old photos I have and can find, document some of the car's past, and update things to come. This thing has had a ton of love, and a ton of inspiration from different members of this forum, dating back most prominantly to 2009-2012 ish

Thank you all for looking! And thank you to all the OGs for inspiring - coredump, spaz, cauqazn, jackie, thecolumbian, archull, krisen, dc5bo, so many more!

Props to k series parts for crazy fast shipment! Ordered wheels 4:30p friday, they were at my house before noon the next day!

RPF1's are in, about to order some tires, and hopefully finish brakes and test fit the wheels this week.

Getting ready to put it all together... it's not the rsx hatch but i guess it'll do

6 weeks later, as she gets ready to be released back into the wild!

More to come, better quality pictures, more from the track, and future track days and installs! Check recent posts for what's going on lately

progress begins months after engine failure at the track last year... bought a new house this year so been too busy to work on it, and had to clean up space in the garage after we moved in.

The car got towed back from the track in May '19, and sat in my mom's garage for several months while we moved. Finally got it towed to the new house, rolled it outside to wash, and then got ready to begin...


and now we wait for list on first post!

6/3 update - wheels are in, preview in post #4

Very nice! Keep up the good work and let us see some videos of you at the track!
I wish I had videos! Been so focused on learning to drive, havn't gotten my phone mounted up yet. Planning to do that before the next track day! Will keep y'all posted.

Super clean. Love the 02-04 A-Spec factory look.
Thanks, I've always loved it. Like my original post, there's been so much inspiration over the years on here with people that have done incredible things with the 02-04 body style! :thumbsup:

6/16 update

A few pictures updated in post 4 - more to come but a look at what's been up!

New brembo conversion from Vision Autoworks (aka Cullen, rsxretrofits, cauqazn, etc but thank you!!)

New RPF1's, new lugs, new stainless lines, new tires, new rotors, new pads!

They are 245/40/17 firestone firehawks on 17x8.5 +30 Enkei RPF1s. No spacer, no extended studs, no modified fenders. I'm still sitting a bit high on my Progress coils, at least it feels that way after this wheel/tire setup. Waiting to install SPC front camber bolts to dial it in, also waiting to research camber plates or other options for more adjustment. The rears have SPC arms, and before the brake/wheel swap I was at about -.6 front -.3 rear. If I go lower, which I may, we'll see what happens. Always open to tips and pointers!

In terms of fitment of Cullen's brembo retrofit, I have about 24mm of clearance from spoke to caliper with these wheels. Again, this is with no spacer, and stock studs. Due to the "bubble face" of the RPF1's anything lower than 9" width, they seem to clear the brembos with ease. Don't get me wrong, I love the flat face of the 9" or up, but read about a lot of fitment issues even with offset as low as +22. I haven't verified or tested anything other than what I listed above

Hope you all come check it out, chime in, hang out for what we do here! Thanks for all the help and inspiration!
