Curious on the fitment, got any pics?

 

I'll try to snap a couple later, easier than digging through my phone I think.

 

But there's really nothing to see, pretty sure it's designed that way. I think I trimmed half an inch or so from my snorkel just to make installation possible without removing the boxes "lid", but it would fit fine without that I think. All stock mounting bits are used, box is bolted in according to instructions.

"Bullet-proof" your OEM TMIC! <<Buy your kit here>>

 

Not currently in stock :(

I see it now based on this pic. Cobb has a lid that goes ontop too right?

STP intake looks to have similar design sans lid (which is important imo).

Yup, not a bad design, though it being that open up front might lead it to suck up too much engine bay air.

 

I personally never really had issues with warm air intakes on my Nissan's, but I've always ran FMIC's on those and I think that's the reason why they were just fine. With a TMIC not much heat dissipation is happening so intake is pretty important, plus IAT sensor is on the MAF, if it was post intercooler it would be much more accurate.

Buy a second MAF/IAT unit and mount it in the intercooler-to-throttle body hose. How many wires does the IAT sensor use? Disconnect those wires at the OEM location and extend/connect them to your new 2nd sensor. Bingo! MAF readings from the OEM location with post-intercooler temperatures.

 

Would the extra 3' of wire change the resistance enough to mess up readings from the new IAT?

I think a better solution is to use an aftermarket IAT sensor, then have it log through romraider. Though you could tap it into stock location with some wire cutting and IAT sensor rescaling.

  • 2 weeks later...

I started testing the K&N intake to get data and to show to people that it's dangerous to run it on stock tune and clutch started slipping, at 3-4k rpm, yay!

 

Shopping around for a new clutch, I think I'm gonna stick to Exedy (have had good luck with them on my Nissan's), plus they are the OE manufacturer for a lot of cars.

 

Going to be converting to single mass flywheel, so if you have an oem one lemme know, goal is to run Exedy oem replacement setup or Stage 1. I think Stage 1 is better bet for my power levels (Exedy claims up to 305wtq), but oem replacement might be more then enough...

That's weird that it doesn't come up with a search for WRX. I put in 2012 Legacy and it came up with several WRX flywheels, some with the pressure plate ranging form $100 - $200. Try that.

This is the one you want. Comes with the right flywheel, and usually can be had for under $600. Holds extra power no problem, been using it for 30k miles with no slippage.

Thanks, I'm actually not interested in running a light flywheel. Not on a daily, and actually not even on my race car. Chatter, drivability, gas mileage actually tends to go down, and much shorter clutch life (more clutch slipping happens). It's just not worth it, plus I already have a light crank pulley, that couple with LFW is usually cell territory.

 

This is why I'm doing WRX/LGT SMFW, it will reduce weight by probably 5lbs from DMFW, so not too big of a difference.

PM Underdog, he can get you what you need. He got me my Spec 2+ clutch and OEM SMFW.

 

If I were you, I would not put anything close a stock clutch back in the car.

 

Hey, while you have the tranny out, install Morre Performance Blast Plates. The tranny shift so much better.

Are you going to post pictorials and a walk-through on a clutch replacement like you did on lots of other projects in your car? You are by far my "favorite" member here, I follow your advises religiously! And many thanks on those stage 1 tweaks to OEM tune. Thank you, thank you, thank you.

Thanks! The goal is to do the usual picture dump indeed. I might need to get a new camera first, using cell phone for oily car pics kind of sucks...

 

I second that! You make some great walk-through lots of pic great right ups. I am strongly considering doing a diy intake like you did.

 

Something to consider with the intake, the parts needed to build it come out to be around $100ish with an Amsoil dryfilter. That's without airbox or your time. I would honestly say GS intake is the best best for most folks, unless you have time and dedication to spend.

FWIW, I have zero drivability issues on that flywheel. Hell, my wife doesn't have any problem driving it, and we live on a hill in Seattle. The only chatter I've experienced is a tiny, TINY amount during hill starts when the tranny is blazing hot (i.e. extended, aggressive city driving).

 

My fuel economy isn't as good as yours, but I wouldn't blame the flywheel for that, its much more likely to be tune/driving conditions/driving style. The little bit of freeway cruising we do I can still get ~25mpg, and my wife can flirt with 30.

 

I'm roughly stage 2.5ish.

 

Max those blast plates are really cool. Hadn't seen them before.

I doubt I can justify spending $400 on a set though, though that GB price was awesome! But stiffening up the case is a good idea, my Nissan transmission had the same issue, case bends, gears sheer. No easy way reinforce the Nissan trans so I went to 6 speed..

It really depends on driving style too. I really didn't like the flywheel on my Boosted Nissan, which also suffered from traction issues too (like all boosted FWD cars do). Flywheel just made it even worse (since you gain a ton more torque at 1-2 gears, but none 3+).

 

Anyway I had to rev the car to 4k rpm just to get the car moving (less momentum in flywheel does that). Because of that city gas mileage stayed about the same/dropped a little (you do gain a little from less rotational mass). Highway gas mileage actually got worse, since your moving at constant RPM, you only waste energy getting to 70, then heavier flywheel store more momentum and will push you through the wind with less engine input then the lighter flywheel with less stored momentum.

 

I'm curious about this and wheel weights too. I just put 17" wheels, that are 15lbs heavier per wheel on my Nissan, City gas mileage seems to have dropped, haven't tested highway yet. Surprisingly virtual dyno read same exact power outputs between 15" and heavier 17" wheels in 2nd gear.

yeah, i'm with you on the moore plates being too rich for my blood. Maybe more like the $200-250 range. Moore makes some cool stuff though. i've got some envy on their TS DP, but i'm getting off topic.

 

The blast plates, due to cost and "basic" construction, fall into the "maybe make it myself for cheap/free" category.

 

As for wheels, can't beat OEM BBS wheels at 16lb a pop in 17"!

That's what I'm thinking too. The trick is finding those long ass bolts. I should do the math of welding it myself (especially since I only have trimix $$$ gas).

 

But that does sound like something fun to build, might even weld my rear swaybar reinforcements while Im at it.

Even though I don't have as much free time to work on cars right now, it was relaxing to just to sit down and dremel away. Thus I completely understand.

The bolt length isn't the only issue. Moore gives you a higher grade bolt, which is why they increase the torque spec on tightening them so much over OEM. That tighter torque is a huge part of why they offer so much improvement. They have a lot of R&D into that product

they just use the highest strength steel bolts - 10.9, instead of the normal grade 8 that is found at these places from Subaru. they'll cost a penny thru Mcmaster-Carr or the such though.

 

actually, you can do better than 10.9, 12.9. And can get it in rod form for not too much and just cut each rod down and lockwasher/nut or serated flange nut on each side. It is way cheaper to get grade 10.9 rod though, and i'm sure the case can only take so much compression...
