Also, sounds like you have a problem that would easily be solved with a second project car to house the K20. :-)

Work on the k20 car while you wait for bp parts. Drive the BP while you wait for k20 parts. Drive the K20 while the BP is broken.

I mean, it looks like you have piles and piles of parts that need to be installed. Get to work.

:dunno:

Maybe I missed the part where you had all that stuff on your car already. I usually install the manifold and turbo as almost the last 2 items. Every time I have to wait for a part I say to myself, what else do I need to do before that part gets here. The parts are almost always ready first, not like you're waiting for piston rings or something.

Come on man, we all want to see this thing go.

I'm not sure what i would do in your case. I like Andrew and i like his parts.

But BPs are gross. Like really really gross. For real.

Ahh-kay ahh-kay, I C ow dis is gonna be mang.

Hey man i'm living this currently. I still haven't touched the motor in Hater for this reason. I'm paralyzed between the easy and expensive button, which is keeping the BP. But that's gross. Or i can go with more expensive and more work on the front end, but not have a gross motor.

So naturally, i leave the BP in the car unopened and get stressed out as it slowly eats itself and blows every seal it possibly can.

Sounds exactly like my mentality at the moment. :brain:

Point taken...Ill get to work.

Crossed my mind...im always looking at cars. I came off the ledge though Im still frustrated...transmission kit should be here soon...plan is to get that attached and Ill get the engine in the car. Most of the parts that are sitting here need to be fitted with the motor in the car. There are odds and ends for sure but most require the motor. Im going to have sixshooter help me cut the hood open for my vents. RyanG told me he was beyond mortified so Im looking forward to shitting my pants when we do that. Ill quit bitching and carry on though.

Just swap the motor...ease your suffering.

Cutting up a body is always a "what the fuck am I doing" moment, especially things on the hood haha

Says the man with experience!

Joos guys don wanna lising to me mang, das-ah-kay, das-ah-kay. Say ello to my leal fren.

I love me a K, and think they're excellent for track miatas, but to me a n/a 4 banger powerband on the street is fall asleep at the wheel boring. I'm sure it's fantastic on the track, but I could care less about that.

So don't think you're "settling" that much. Hop into a 400whp turbo miata and you'll be laughing with excitement ;)

aidandj 10-12-2017 02:19 AM

Hop into a 300whp turbo miata and you will be laughing with excitement.

Padlock 10-12-2017 09:44 AM

After being use to 3 relatively stock naturally aspirated miatas and boosting one of them on a very modest 7 psi, a 160whp Miata is a honest fun time.. its an exponential curve of fun increasing from there as you turn up boost units..

I think there's more to the K swap than just the power delivery. It's the simplicity of still being naturally aspirated to me.. you don't get the low end torque one could expect from a turbo car (which makes it fun to street), but its also a million times easier to wrench on, is lighter, and has more RPM's to use. If in the future your 230-250whp in it isn't enough, K's have proven to love boost.

Got to ride in a conservatively done 205whp K20 NA at MATG. Sort of changed my outlook on the need for torque in a car so light to begin with.

concealer404 10-12-2017 11:32 AM

Also: Torque by gearing.

My 108wtq BP doesn't exactly feel gutless with a 6spd/4.30 behind it.

Yeah i didn't have a fun time with my vents. Took a long time, the OCD in me isn't happy with the results, and i really don't want to ever do them again.

Have you ever taken apart a K engine? A BP is like a lego set compared to it.
And What is there so much more complicated in a basic turbo BP? 2 oil lines and 2 water lines? everything else unbolts with the quickness. I mean, there are legitimately very few modern cars out there more simple than a Miata, and very few modern engines simpler than a BP. I can't even think of many cars easier to wrench on....

I mean I get it, it's the feeling of simplicity and reliability that is the appeal here. And in some ways it is simpler, and in most ways its more reliable, at least on track anyways, I just think most people get carried away lusting after something they've never really even owned. "K SWAP BRO, SO EASY YOU CAN DO IT ON YOUR LUNCH BREAK".........."brb, doing kswap"........."ok done, ready for the track"............

Now I will admit, I also have not owned a K Miata, but I have owned 4 RSX's many years ago, a TSX a few years ago, and various other K cars, so at least I speak from some sort of personal exp.

In the future, after OP finishes his epic BP build and enjoys it, I would LOVE to see him build a boosted K :D

and the joy of constant 2-3-2-3-2-3-2-3-2-3-2-3 shifting on any autox course and 5k rpm buzz on the hwy.

had 6spd-4.10 on my msm and hated it. Much happier with my current 5spd 3.9 and 240whp

concealer404 10-12-2017 12:05 PM

I don't autocross, and 5krpm is like.... jail time and rubber hose beating on the side of the highway. ;)

My car isn't a highway car to be sure, but it's not due to RPM. It's quieter at the 4200-4500rpm cruising rpm than it is at lower speeds and 3000-3500rpm exhaust wise, though. :)
