I did end up using a ported RSX Type S oil pump kit from PRL, bolts up easily and less to mess with than the stock oil pump for sure. https://prlmotorsports.com/k24z7andk24z3prbtype-soilpumpswapkit.aspx I also used new k24z7 stock pistons as I was burning a decent amount of oil and reused the...

Has anyone on here completed a K20z3 headswap that could help me out? I put the entire head on my stock block but am having troubles with starting. If i try to start it, it will turn over fine but will never start, however if I disconnect the camshaft sensors, it WILL start and run... Any ideas...

Hey guys I’m gonna be running 17x9+35 on 235/45 tires. What kind of rubbing and all that will I have? How much camber do I need to run? I test fitted the wheel up front and have maybe 3-4mm of clearance from my coil over. I have my rear fenders rolled.

Update, after going through a few more revisions, it seems that the issue stopped happening. Guess it had to of been some sort of tuning issue, as I changed nothing on my part. I'm just glad to have it running good, hopefully the final revision is trouble free too! Car pulls good now that I...

If I disable it, the check engine light will never come on for that particular code, but I really am trying to avoid that because that just seems like a bandaid fix to me. It won't happen again but if I do somehow have a major issue with the MAF, I wouldn't ever get a code thrown. And I tried...

Alright, so I have a known good sensor from a 2015 Si installed, still throwing the damn code lol. There's no wire damage, unless it's very well hidden. Can't find any leaks in couplers or anything like that, so I'm out of ideas at this point. It just randomly throws the codes on pulls, maybe 1...

Yeah I think I read somewhere about 12's being difficult to work with haha. But my MAF wire definitely isn't like that, that's pretty crazy. I'll take pictures sometime tomorrow, my friend and I are gonna pull it apart and see whats up. He's a Honda tech so hopefully he can figure it out. I told...

Huh, I never heard that about the skunk2 intakes, that kinda sucks haha. I did buy the car with some modifications on it, it came with the RBC, Catback, and Takeda intake. I work at the dealership I bought it from and as soon as I saw it on the truck from auction, I knew I wanted it. However, I...

Today I just swapped my old short ram intake back on and flashed my old tune to see if the problems persist, hopefully it will help me narrow it down. No obvious wiring defects, never set any codes off just from messing with the wires. If it keeps going, I'm gonna put the new intake back on and...

Yeah, I bought the retune from Vit specifically for the intake, so I'm not sure whats going on... Like I said, I'm at a loss haha. Unless my MAF somehow did get messed up.

Hey everyone, just recently I intstalled a PRL cold air intake kit. I'll list the aftermarket stuff real quick to help VitViper Tune PRL CAI with J37 throttle body with PRL adapter RBC Manifold RDX Injectors 410cc Skunk2 Catless downpipe with Ultimate Racing catback Anyway, I installed this...

He was having issues with his tune, it was corrupted when he uploaded it, and whenever he used his two step, the car would stall. Even with all those issues, he ran a 9.04. That car is awesome though, I've personally seen him run all over 5.0 mustangs with it

No aftermarket flywheel for me, decided it was too much trouble, not to mention a lot more expensive then just doing a stock clutch which already feels good. Just recently took a trip to our local drag strip with my friend and his supercharged 8th gen Si. Had a lot of fun, even if my time...

I hate to ask a question that has already been answered, but has anyone done this on a Si with Navi? I'm willing to try if no one else has.

I have a Flashpro, I think I read about that. You have to turn off misfire detection, correct?

Had another tech look at it, and they are convinced it is the throwout bearing. Getting it replaced under warranty, but I'm debating if I should go with an aftermarket stage 1 clutch and lightweight flywheel or not. Is it that big of a difference?

Tried to get a couple of better pictures, sucks that my only source of a camera is an iPhone 5S. Next mod is a pair of UAE headlights once I pay for the next semester of school!

Most of the mods came with it. I ended up buying my own flashpro as it was tuned but I couldn't change anything without one, although the tune that is on it right now seems to be ok, so I have not done much with that. I hope to tune through Vit soon though. I also purchased the taillights...

Hi guys! I've lurked around here for a while, but never bothered to post. I have a 2012 Si that I have been working on for awhile, and I thought I would post some pictures of it. I actually bought it from the Honda dealership I work at with many of the mods that came on it, it came from an...
