Whoops, I did a thing:
SR20 T25 in need of a rebuild. It's small but I feel that having the T25 flange will give me a lot of upgrade room in the future. I think I am going to shoot for 220whp on E85 which should be do-able without too much boost I would think

Alright anybody got any issue with this purchase? I have the NB Sport front brakes, and 1.8L rear brakes. It will be a casual weekend racer with both autocross and light track duty. Porterfield's front and rear w/ Prop valve and I'll be running ATE Super 200.

Hahaha no worries. Sarcasm doesn't come through very well in text. Yeah it seems like a ton of people are doing the 8 and 10 combo. It's not a daily so I'm not too worried about that, but I also would prefer a pad that isn't too noisy or needs a ton of heat to do anything.

While this isn't an apples to apples comparison (since mine are the TSE 11.75 front), I run the XP10/8 combo. When we went for a ride at 45-50 degrees, they still worked great, even when I first left my house. I expected them to be very dull at low temperatures, but they surprisingly work great. With that said, before they were fully bedded in, they were scary at low temps.
If you're going on a road track, I would go overkill on brakes. That's why I narrowed my choice down to XP10/8, and if I would've waited a few weeks until OGRacing posted about the PFC011's, I would've gotten those. That's what my roommate runs, and he loves them. The PFC's do have a lot of dust and noise. My XP10/8's only have a very slight squeek at low speeds, if you're soft on the brakes, but dust isn't too bad.
TLDR: Either put up with noise and dust or have two sets of pads.

Porterfields lasted just one track day (total noob) for me. Worn down almost to the metal.
Performance Friction race pads for the track for me now- let's see how long they'll last. But I don't think they have 1.8l rear pads.

To the others I got the Sport brake hardware for a hell of a deal. Think it was like $50 plus shipping so I couldn't pass it up. Eventually I'll step up to the 11.75" setup. Ordering the XP10/8's now and I'll see how they work.

Okay guys so bit of an update: The winter has been long and hard on my bank account but I have made some small steps. Firstly I set out to fix that damage on the rear quarter panel. I decided since it was a track car I will do it myself (Learning process) using a spot welder. For those who don't know basically you need to strip the paint (see below) and you can weld these little studs onto the body. Once on you use a slide hammer to pull it out. These are the first pictures, I'll do more today. Obviously you apply bondo and repaint when done.
I was told racecars don't need paint #weightreduction
Some of the studs welded on:

Also it might be a month or two before I go turbo so I installed a test pipe. It was cheap (obviously) and I assume it'll free up 1-2 hp or so but not enough for the butt dyno to feel.

Conclusions... It's a cheap an easy way to drop a tiny bit of weight, free up a hp or two, and increase sound a tad. For me getting an NA exhaust only to upgrade to a 3 inch won't be worth it so that'll have to do. The butt dyno says it feels a little bit more peppy but nothing quantifiable. I'll be bumping up the timing in the next week as well as a harddog double X rollbar if all goes well. Cheers!

EDIT: looking closer at OP's photo of his turbo it is an m24. Can someone please clear up my confusion.

Update:
So I've finally got some forward movement. Here's the gameplan...
MIATAATATATA
Phase 1: Maintenance (Oil, coolant, brake fluid, air filter): Done!
Phase 2: Safety (Roll-bar, Brakes, Lines): Almost done
Phase 3: Track-ready (Tires, suspension, alignment): Not Done
Phase 4: Driver prep (Get more track time and adjust setup as needed): Not done
Phase 5: Getting there (MS3X, Injectors, Get it running): Not done
Phase 6: Throw the damn turbo on (Throw the damn turbo on): Not done
Oh and this is happening:
Also I was able to take the car to work and I found one big thing out... The radio blows dick. I can barely hear it. I ended up just putting my phone with Spotify on in the cup-holder and it was an improvement in volume and quality. SO the radio and speakers came out. Need that space for gauges anyways
