Mouglie's Engine Rebuild
 
1 Attachment(s)
I plan on getting my engine rebuilt so I can boost it but i have never done this before so i've had several friends give me advice as to what to expect.

I ordered the turbo pistons that flyin miata offers and it says 2mm overbore. Does this mean the cylinder in the block has to be bored 2mm for the piston to fit?

Right now i'm looking around town for machine shops to get some head work and see about getting my pistons installed.

i'd greatly appreciate and ideas or comments about building this engine
the right way to handle some boost...

yeah, they do overbore so that you can clean up the cylinder walls by boring it out 2mm.

Hey Mouglie, are you Russian?

You don't know what an overbore is and you are planning on building the motor yourself?

Good luck.
I'd say go to a engine builder near you with a good reputation, give him all the parts and come back with a motor you can drop in. Unless you are willing to spend countless hours reading up on shit and learning, and very possibly pulling it back out to re-do once you figure out something isn't right or you loose compression after a thousand miles.

no Sam, i'm hispanic.
but i love the girls from TATU, lol...

crashnscar: i know what bore is, that stuff i'll leave to the machine shops to handle. The only thing i'm taking care of is tightning screws and bolts which doesn't take a genious to figure out (sorry not trying to be rude). I have a main idea of how it works and whatever i don't i will look for help or read. Thats how I learn.

The pistons came out the block yesterday and the main bearing showed signs of wear and tear, not to bad but enough that i have to get so work done to the crankshaft, new main bearing and the piston bearings...

Is it better to buy a new crankshaft or just get mine balanced?

:jerkit: You managed to fuck up the easy task of using a headgasket repair solution which is what prompted this rebuild. I have to wonder if you are capable of tightening bolts and measuring clearances.

Mouglie 05-26-2008 02:15 PM

the rebuild was gonna happen for my turbo, this incident just hurried the process. I know about measuring and clearance, you use plastigage for that, i've never used it but i'll get some help putting it back together. I'm being extremly careful now, lol...

Saml01 05-26-2008 02:15 PM

I asked because Mouglie is the name of the main charachter in a very famous Russian children's movie.

comin along nicely

Mouglie 05-26-2008 03:14 PM

i know there's many that just eliminate the ac but i really want to keep it, so i'll have to place the oil pan on the block and the ac bracket so i can figure out what would be the best location for my oil return line tap. I'm thinking about having two fittings, a 1/2 to 10an and then a 10an to 5/8 barb fitting so i can hook up a rubber line for now. if i ever wanna upgrade to a stainless steel line i just eliminate the barb fitting...

Mouglie 05-26-2008 03:24 PM

another thing is i haven't installed any gauges and i'm not a big fan of the a pillar gauges, nothing wrong with them its just that i wanted to go with a sleeper style... so i plan on having my gauges installed before the turbo goes in... so far here is what i got.

fiberglassed my whole dash and
wrote what i wanted and where... mock up
http://a427.ac-images.myspacecdn.com...3326ae16ea.jpg
this is where my gauges will be, all angled towards me
and a little bit closer to me and lower...

here its fiberglassed and i'm just waiting for it
to cure so i can proceed...

they are all digital gauges except for the boost, they will be behind a plexiglass piece tinted 50% so you can only see them when they are on. i need to finish the hood for it and i can start sanding it for paint. I'm thinking about Flat black...

kotomile 05-26-2008 03:36 PM

You want your V1 shoved into the dash?...

I'll keep mine up in the windshield where it will, like, work and stuff.

Mouglie 05-26-2008 03:40 PM

V1

the v1 will be mounted behind the rear view mirror, i have a remote view screen that came with my V1 so that one is a radar and the other is a display. so yeah, i want the display lower so ppl behind me don't see it.


they call it the concealed display if you wanna check it out

so youre going to block the windshield with gauges?

Mouglie 05-26-2008 03:51 PM

lol... it looks higher than what it will be. its still a work in progress. Total will be 4 inches from the normal dash.

it was placed there as a mock up to get an idea of what it'll look like but the gauges will be lower and a bit closer. You won't notice them when i'm finished... (well thats my goal)
