Miata motor rebuild time......

[chris101]

after bad luck with 2 used engines (1st one went back due to 80% leakdown on Cyl #1 and 60% on cyl #4 (mind you our broke miata was 80% on #2) ..and then the 2nd engine had even more issues I won't go into so it was returned for refund as well...

so the decision was made to just rebuild mine since the block (fortunately enough) was NOT scored.


so pretty with brand new pistons installed:

and here is just before the oil pan went back on:

..some progress again:

That's too funny. Those Miata motors look almost identical to mine. Even the bore spacing looks familiar. Makes me wonder who they both ripped off their engine designs from. (Honda maybe...)

Building with fresh OEM stuff, or some forged stuff?

 

[chris101]

fresh standard OEM from mazdaspeed program I am part of (it is required to be 100% stock for spec miata rules)

I heart Miatas. We just saw about 20 or more spec miatas at Autobahn CC on Friday. All 20 of them going from a standing start was the most hilarious noise I've ever heard in my life. It was like 50 million bumble bees all taking off at once right next to your ear.

Shoulda painted that block, though, dood.

Too bad it has to be stock, I would have gone the lsx swap route. Good luck with the build.

Everyone wants to put a LSX into everything now a days. I could get down with it on almost anything except Rotary cars.

 

[esteinmaier]

Yea. LS motors are pretty rad, but we all need to start embracing jet motors instead.

 

[B serious]

Doesn't Jay Leno still have that jet bike? It's like a 1-3 second lag between on throttle and off throttle.

The on throttle lag would be annoying. The off throttle lag would be F'ing scary.

Thread jack, BTW. Sorry.

That's actually kinda cool having to race @ stock spec. Bet it makes for an interesting race!

It's a 4 cyl. DOHC, they all look very similar, look at a Nissan SR20, or a GM EcoTech 2.4, shit even a GM Quad 4, they all look very similar without accessories and a valve cover........... Oil filter location does look very honda-ish though

And to the OP, good luck with the rebuild
