So I finally got around to putting my motor together, I'm still short 2 tension bolts that are in-transit right now... There are a bunch of pics from rotor assembly to essentially a finished short block:

13b short block assembly

my wife managed to catch me on camera... now you all know what I look like, https://www.nopistons.com/forums/pub...DIR#>/moon.gif

engine looks good and you look like an angry man LOL



i took a quick look at the pix i'll check em all out when i go home https://www.nopistons.com/forums/pub...DIR#>/wink.png

thats gonna be a good motor, new rotor housings :bigthumg:

fd corner seal springs.



mike

Were the corner seal springs visible in any of the pics? I think I may have forgotten to take a pic of those. Clearancing those side seals is a pain in the ass, I eventually ended up using 220 grit til they fit and 600 grit for the finish, seemed to work ok but damn my fingers got torn up.

you can see the bag in the back, nf01-11-c24

i use a dremel to do the side seals, its round and it does most of the work for you



mike

Cool, looks good.

After watching the RE-amiya video vosko has and seeing that guy go through side seals on the small bench grinder... I decided against using a power tool for that step https://www.nopistons.com/forums/pub...DIR#>/wink.png Next time I'll buy some extra side seals so I can try the dremel...

the dremel works great, with a not new stone it works pretty slow.

i put the dremel in a vice, and i had something to keep the seal square



mike

pimp ****!!

just an update, some new pics:



long block assembly pics



everything but the water pump / housing and oil pan etc have been put on as of now, you can also see the added material on the S4 LIM to block the intermediate housing heat riser port... I should be finishing up this weekend hopefully.



Those water nipples on the rear housing and water pump housing have been pulled, holes tapped, and plugged... since I removed the thermowax and the coolant from the BACV.

looks awesome. congrats!

cool, ill be at that stage next week



mike

groovy, thanks vosko https://www.nopistons.com/forums/pub...DIR#>/wink.png



hopefully it runs when the time comes... https://www.nopistons.com/forums/pub...IR#>/dunno.gif

Looks good man, thats a phatty n/a :bigok:

Your Intermediate Ports look bigger, Ported?



Just curious as to what it cost you? And what you replaced?

sorry for the fng question but:



wuts the distinction between short block and long block?

short block is just the keg, no manifolds, accessories, nothing on it. A longblock is the whole engine, with all manifolds, accessories etc.

So, when in the car, there's no distinction between short and long block, am I right? Just a matter of what you're dealing with outside the car, right?

yes it a term used when the engine is outside the car, because its always a longblock when installed and running.

its kind of a piston engine term. a shortblock piston engine is just the bock, pistons and rods.

a long block is the short block with the cylinder head (s)



mike

so what's the difference between big block and small block?

thats just a piston motor term, big vs small, referring to two significantly different gm v8 blocks. (afaik)



short vs long is just what level of assembly they are at, i have the habit of calling an assembled 13b with no accessories (just housings assembled w/rotors inside) a short block .. i've seen others use it this way too with rotaries, makes sense to me. Since I've moved on to the oil pump, front cover, and now water pump, housing, oil pan, intake manifold etc it's approaching the long block level.. (in my vocabulary anyways, someone smack me if i'm way off on this)



Dac:

The housings are all street ported, via mazdatrix, intake and exhaust.

End housings are S5 NA 6 port housings

Intermediate and rotor housings are S5 Turbo housings

all are new and ported.

For pricing info check out mazdatrix' site, I don't wanna talk about it :redface:



Just for completeness, inside are two new S5 NA rotors, hardened stationary gears, FD corner seal springs, all new 3 piece 2mm apex seals (oem) and all other seals are new oem.



the bill was pretty big.

yep, BIIIIG BILL!!!!!!! :bigthumg: Looks Good, We'll have to run my Pineapple against yours someday!

wow, you bought all that new? thats not cheap, i know https://www.nopistons.com/forums/pub...#>/biggrin.png

should be a really tight motor though



mike

banzai, sure https://www.nopistons.com/forums/pub...DIR#>/wink.png unless you wanna race, then it's gonna have to wait til i get one of those miata transmissions too, heh heh



I've been contemplating the possibility of turboing this motor later on, but the more I read and watch, the more it seems NA is more useful on a road course, which is what I want to get into... road racing

maybe we can have a nopistons meet there sometime next summer :bigok:

i had my gsl-se out at thunderhill last summer and with a good driver in it he was catching single turbo fd's



mike

lol a good driver?? so u werent driving right? j/k thats a mean looking engine i kidna wanna do my own build but a) its too expensive and b) i dont have the experience i guess my first 7 will just be a stock turbo II or more than likely a stock gxl... BUT I WANT BOOOOOOOSSTTT!! actually more than anything i just want to be able to fit a nice BoV for the intimidation factor

they have bov sound generators, i think they cost more than a real bov, and sell really well in the rice boy croud.

:rice:

thanks for the pics :bigok:

yah, it want me driving, i was catching 240sx's
