The PP on my Fm2 was a potato chip, I think from day one. The absolute first 1 foot of use it felt like shit. Pulled it back out, inspect, it was like .020 variance. Required a tricky set up to re surface. Now it feels 100% better. Maybe 110%.

ACT XTSS has been flawless for years. Smooth to engage on the street and strong enough to handle many track days and several drag launches. Will buy again if it ever wears out. But it may not wear out. I've had it for ? 7-8 years now, maybe more. It's even easy to load the car on the trailer with it.

Thanks for the feedback. I'm working on something right now and should know shortly.

As an aside, any point going from 1.8 to sport brakes F/R or even just front? I know pad availability is limited but it should make the braking performance a little bit better. I know the *real* answer is to go bigger in the front, but I might have to wait on that. If refreshing my current 1.8 brake setup is going to cost even 40-50% of the upgrade with newish hardware and pads etc... still no bueno? I guess 1.6 folks will probably grab the stock 1.8's.

Car will be street and autocross. Might try a drag even for the lulz. I likely won't have the cash for an HPDE style event for a while, but really want to try to get out atleast once next year if I'm confident my car will survive lol.

then use the stock brakes and load them with G-Locks. wil be fine.

sixshooter 02-08-2018 06:25 PM

Leave the stock brakes alone. They will be more than adequate for Street and autocross even at high power

I like Sport brakes. I don't like the terrible pad selection. Would stick with 1.8s on a street car.

Do as i say, not as i do. Ignore that i put Sports on my wife's DD.

Pretty sure I got an 03 with sport brakes I could let go for cheap.

I'm told that fast CSP autox cars backdate to the 1.6 brakes to reduce weight. :)

Can we get a thread title change?
Retard the breaks

lol I was gonna say that, but I decided to be nice.

Drunk SoTH is the best SoTH. Please don't correct the spelling in the title.

Also, we're not quite past the pistons yet. I'm going to have to go with a premature thread title change on this one dawg.

Pretty much. I'm pretty sure FM Big Little brake kit was a product of this.

Motor's out but unfortunately the guy I was going to trade heads with backed out last minute... like the day we were supposed to meet.

So the question is...

A) Try to find another trade: nb1 for nb2 head
B) Sell NB1 motor whole and buy NB2 head. Motor might sell better together.
C) Do valve stem seals and valve springs on nb1 head and just raise the rev limiter. It likely won't make more power up top (can add boost though), but it should help not implode things if i miss a shift or such.

Thots?

Guessing the vvt head master race folks are gonna win this round, eh?

which option gets you to finish the project fastest and not buy/sell 500 more times and never actually finish it? I vote that one :D

I mean... I've been quiet about this for a bit. I haven't bought and sold anything 500 times lol. Just been really busy with school and trying to figure out what to do with my life style shit.

That said, the block is done being assembled at the machine shop. Soooo....

Other things?
-FM2 Clutch
-ID1k's
-Blah
-More Blah
-And some blah blah blah too for good measure :p

Figured it'd be easier to sell a full running motor instead of trying to sell a block later. I definitely like the idea of VVT and have seen it produce results on here because obviously, but at the same time less complexity can be naice.

sonofthehill 02-16-2018 10:15 PM

Ez pz.
You should sell me the nb1 head real cheap shipped. Then take that cash, plus a bunch more, since I low balled the shit out of you for the head, and buy an NB2 head.
:bigtu:

So the serious answer isssss....?

patsmx5 02-16-2018 11:11 PM

Run what you have, it will be fine.

18psi 02-17-2018 12:44 AM

Correct

Keep the bp4w. Finish the engine. Enjoy the car.
The vvt on these cars is not a big enough improvement to sell a whole setup and start over just for it's sake.
