JZ S12 BUILD, RIP 2012

I mustve missed something but what happened to the sohc that was in the 240? thought it was good?

the sohc is fine... this is the dohc i was talking about last week

Thats cute <3

paid almost nothing for it



good to have this time around, gotta figure out how to even use it

OMG an SAFC2... PLEASE tell me you aren't actually going to use it?

why not, the motor is stock, im not relying on it. i just dont want to end up in a minor leaning out issue like last time

SAFC = engine death sentence.

If you want to avoid a lean condition, clean your MAFS, clean the injectors, and run a little richer of a tune. Oh, and get a GOOD wideband and a nice visible gauge.

ive got a aem wideband, and how do i run a richer tune? just like that

Adjustable fuel pressure regulator is a real easy way, but really the SR stock tune runs really rich as it is IMO.
ROM tuning is another easy DIY way too.

But please, PLEASE stay away from that SAFC, it accounts for damn near 70% of SR failures out there... Because people are dumb shits and think it's a magic power making device and allows them to jack their boost up to 1.5bar with out bigger injectors.
Most people just don't realize how an SAFC works, it does more to your ECU than just change fueling.

(I hate them with a passion BTW, as if you didn't notice already)

nismo200sx16 is runnin one on his SR setup...you should talk to him about using it if he doesnt chime in on here

Was just an example.

If the engine is 100% stock (boost and all), then you should never need one of those.
"The only thing the AFC can fine tune is how much more detonation you want."

uhhh, i want less? lawlz!

my friend uses safc but just to monitor shit, he doesn't actually tune with it at all.  So maybe you could just do that or something >.>

ill give you $20 for it david

Just don't get a click torque wrench, they = bad for engine assembly.
Scale type ones are the way to go, and don't forget to pick up an angle indicator!

ive got a click type, and scale type. but they are both old as fuckk

old as fuck doesn't apply, as long as they aren't broken or abused.

Not THAT often... Depends on use and abuse.
If you're a dick and don't turn it back to zero when you done with it, then yeah, it'll probably need to be calibrated.

But that shouldn't matter anyway, because you shouldn't be using a click torque wench when building engines anyway! :P

Can you be absolutely sure that it's set to the right torque?
Most I've used are just a dial it "close enough" deal (digital doesn't count), a scale type you SEE the torque you're at while you apply it.

I like seeing what's going on while I do it.

well, i decided to order arp main studs

and i checked the piston ring gap, there within spec. no need to file fit.

+1 on the dial torque wrench, and they are so much cheaper, like 1/4 the price of a good ratcheting type althought they don't look as cool....

Good choice on ARP, I would use them on the rods too, don't reuse you stock rod bolts, they will probably stretch to cause the famous sr20 rod knock and most importantly, you don't want those to fail spinning at 7000 rpm.... will make a big chunk of worthless alluminium... or a hell of an expensive paper weight and you already have the ca20 and ka24 for that use ;)

Not to be a buzz kill, but ARP mains will distort the main journals differently than OEM bolts.
Most people that plan on using studs have the main journals line bored, otherwise you're taking risk of spinning a main bearing.

Rod bolts and head studs are ok to use in replacement though (since OEM rod hardware is already a stud, and the head surfaces should be milled flat).

i apreciate the concern but im pretty sure ill be fine just popping the arp main studs in

No binding, but what kind of oil clearance do you have? If it's too tight anywhere on the bearing, you'll risk spinning it.
Just IMO, it's your engine.

^^^What is said...

Plastigauge it just to be sure... better be safe than sorry... you should check every bearing surface while the engine is out of the car... make sure you rebuilt it right the first time... nothing sucks more than skipping a few step to get it on the road faster/cheaper and having to go through it all in a couple of miles.... just my 2 cents

<33333 new temporary heart! hope fills me! i miss drifting



100 DRIFTERS OF DECEMBER HERE I COME!!

ka, the good old fall back!

^^^ That 240 likes the the ones where im at  but i say that a little  bit better shape  :laugh: no joke tho

UHHHH

overkill! bye bye transmission! this is gonna be epic

Overkill? True
Worth it? True
Fun? True
Win? True
:thumbsup:

and ive spent zilch so far.

WTF is that torque converter doing in the background? just chillin?

Twin disk clutch FTW

I wish I could get perfectly good ka24de's for free over here.

Fucking david king of free shit.

damn looks like i'm not gonna be the only ka s12 at drift nirvana. lol

so it's .. the 4th engine in that car if I haven't forgotten any!

You should start your own swap shop lol :P

yeap thats engine number 4

David B on 08:54:02 PM / 24-Nov-10
and, free junk of the day!

yea dude, i pick up around 4-5 motors a month

swaps at my house or a friends every week

where does all this shit come from!

i scrap alot of it/sell it

so, if your s12 needs a ka swap...better hook that ish up to a truck and haul it to va because david has all of the kas in the east coast go through his garage.
