More than I would like to admit considering I am still using a HLA head...

Block labor: Bore & hone, clean, resurface, align hone mains, hone Connecting rods to size, hang pistons, file ring gaps, clean/polish crank, assemble shortblock, resurface flywheel, balance rotating assembly.

19 hours

Cylinder head labor: valve job & resurface

4 hours

23 hours at a rate for a high end machine shop who builds most of new englands spec miatas as well as Audi motors for EPL... and you end up with a bit shy of $1800 **shoot me** I wish I didnt spend the money on the head, but I didn't have the cash to build up a NB. Plus i want VVT down the road.

Oh and the main reasons for my bad bearings were low oil pressure, and too tight of oil clearances on the rods. This is what I get for doing a half ass build myself a few years back without knowing anything about proper ring gap & clearances.

You should just add the an fittings man.

240_to_miata 08-17-2012 06:39 AM

I can run a catch can perfectly fine without them. I can put AN fitings in a 99 or VVT valve cover when the time comes. The awesomeness factor of this car can only go so far. my wallet hurts... and i want it done.

Shit man, that's not really horrible by any means. The 1800 includes internals right? Thanks for giving it to me straight. Sounds like you got it done properly though, I've got my fingers crossed for you that this motor lasts a long while. Always love seeing these builds, it reminds me why i need to wait a few more years before I build a legitimate motor/turbo setup. I'm destined for stock limits for now.

Anyways, subscribed. Excellent thread as usual Dave.

There is nothing like a brandy new short block!!! looks sick. Cant wait for the rest to go together. Do have a deadline set at this point? I really want to see this at AutoX soon.

Good Luck

Evan

Sadly no... That's just labor only. I think their labor rate is about $75/hour

And Evan it really depends on how much time I waste car shopping wih Natalie and how busy I am at work. I hope it can be tied up by the end of labor day weekend so I can enjoy it for a few months

Did they give you any kind of warranty on the engine?

240_to_miata 08-17-2012 05:06 PM

not specifically. But I know through other people that they will back their work to a point. I don't expect any engine builder to say "hey, I cut holes in stuff and bolted stuff together...now you go tune it however you want without any input from me or a professional... and if you fuck it up I will be sure to give you free parts and labor". They documented all the clearances and built it knowing my power range and boost levels. If all of that is proper than any issue with the motor is most likely NOT do to their craftsmanship assembling the bottom end.

Well said Dave! this is really how i feel about it. Let me know if you need any help. I would even be willing to go car shopping with Natalie to help out :eek3dance

240_to_miata 08-17-2012 09:35 PM

LOL thanks. I'm sure I will need something along the way. I picked up the spare HLA from jeff the other day, so I can put the cams in the head and do other small stuff if I get a chance this weekend.

Powderocated the valve cover.

Metallic Charcoal. I forget the exact name.

The oven... Thermostat is busted so I have to sit there turning the heater on and off manually. FML

Results... Could have probably stayed in a bit longer to flow out better, but it looks good.

Nice, do you still want/need those bolts?

240_to_miata 08-20-2012 07:28 PM

I probably SHOULD use them..yeah. I just dont know when I can meet up. Maybe Friday?

astroboy 08-20-2012 09:43 PM

I could just throw them in the mail if you pm me your addy. Can't guarantee I won't stalk you afterwords though.

240_to_miata 08-20-2012 09:49 PM

Getting somewhere...

https://www.miataturbo.net/attachmen...ine=1346291066

Valve cover is just sitting there for now. Gotta do the timing belt first.

Hopefully I can grab the last of the gaskets I need and get this running this weekend

Other than a few small hiccups ... it runs

https://www.miataturbo.net/attachmen...ine=1347220681

My battery was DEAD and would not take a charge, so I got a new one. I also intermittently would loose signal to my IAT sensor. It turns out the terminals on the sensor were rusty. So much for GM's weatherproof design. Makes me LOL at the fact that they put their ECU's in the engine bay.

I primed the motor for oil pressure, and then cranked it over. Started up first try. . . But it sat at 4000 RPMS. After checking every vacuum line and connection I determined it MUST be my IM gasket. I think the Trackspeed kit included the 99-00 gasket I spaced out and used it anyway. I ordered a new gasket and a new slave cylinder (mine is f'ed).

The engine sounded great tho! I just wasn't about to run a brand new motor up to temp at 4000 RPM's. Ideally I wanted to high-idle it (1500 rpm) up to temp and then drive it to set the rings. It's never fun when you have to diagnose a problem on a fresh motor. I'll replace the gasket and start it back up. HOPEFULLY that solves the issue.

curly 09-09-2012 05:07 PM

That should cause a nasty sound, I'd disconnect your idle valve before going through the trouble of replacing the intake manifold gasket.

240_to_miata 09-09-2012 06:30 PM

Idle valve disconnected, all EGR ports plugged, PCV & brake booster hoses plugged... nothing

I even held my hand over the throttle body... that brought it down to about 2000 so it is still getting air from SOMEWHERE. I just dont know where.

All my plugs did look the same, but then again I only ran the engine for 10 seconds at a time.

I thought timing may be a possibility, but if the timing was causing that high of a spike it should stall out if I blocked the throttle body completely.
