very nice dude, looking good...

the 17mm head banjo should be water line and the 19mm head banjo should be oil line

David BMar 9, 2010, 11:01 pm · #1253

where can i order those lines?!

made one side of the i/c piping out of rapper dans old shit haha
dont get on my welds, i have a lincoln weldpack 100  with that fluxcore dogg

each side is 1 piece and slides right out of the bay

Just one thing I'm spotting....

You have the intercooler upside down for best cooling. your pushing hot air, it will stay up at the top.

Flip it over for best efficiency. Inlet and outlet towards the ground. But with that one, I dunno if it will make a difference for a t25. It's massive

JayMar 10, 2010, 3:16 am · #1256
David Bi cant flip it upside down, im keep my bumper support and id have to notch it out on the chassis where it mounts, and use more piping

But you just answered how you could flip it the "proper" way
"
I'm being picky yes. It should be fine with your turbo, but anything bigger and I would flip it to be the "proper" way. For future reference, best cooling is hot air in at the highest inlet.
Im putting proper in parentheses because it's fairly subjective, even though it's just simple physics
David BMar 10, 2010, 3:20 am · #1257

well iff i get a t28, ill probally get a smaller i/c, run it normalways, and get 45 degree elbows welded to it for the midmount, and redo the piping. atm i just wanna drift!!

JayMar 10, 2010, 3:21 am · #1258

That's the spirit!!!!!!!

Oh, and your welds look good for what your workin with. My compliments. Just make sure the motor torquing won't pop off the piping. If you have the poly mounts on there, or pucks. Should be golden
David BMar 10, 2010, 3:38 am · #1259

i have stock mounts with window weld in them.

i wanna make a strut bar for the motor, does that sound gay? to keep it chill.

just orderd oil and coolant lines from fr sport. should be here next week

seishukuMar 10, 2010, 3:46 am · #1260

Oh come one, I can make welds that look like TIG welds with my Handy MIG.

Whatever works man, ghetto/rigged/ratty/whatever seems to be the "in" thing these days anyway.

Oh, and the exhaust will clear fine with the stock cast O2 elbow, but be careful of aftermarket ones, they're usually made for RHD cars and will put the elbow into the frame rail (ask how I know.)
If you get an aftermarket one, make SURE it's make to fit LHD cars.

David BMar 10, 2010, 3:49 am · #1261

whats the thread pitch for the studs? im missing a few studs off the turbo

JayMar 10, 2010, 3:51 am · #1262
David Bi wanna make a strut bar for the motor, does that sound gay? to keep it chill.

Nope. I've used chains to do that very thing before. Just to prevent it from torquing over in any forward gear. Old tried and true hot rod/rat rod/muscle car/drifter trick

seishukuWhatever works man, ghetto/rigged/ratty/whatever seems to be the "in" thing these days anyway.

Yup. The chains worked well in my application
David BMar 10, 2010, 3:53 am · #1263

im using the stock throttle cable for now, i was able to run it under the injecter harness and make a ghetto bracket to make it work for now. is dohc longer?

bled the clutch, added slave cylinder, its got good pressure still  man it feels so good to push that clutch pedal in

seishukuMar 10, 2010, 3:55 am · #1264

I think they're M10x1.25.

Edit:
And the turbo outlet I think are M8x1.0, I could be wrong though

JayMar 10, 2010, 3:58 am · #1265
David Bim using the stock throttle cable for now, i was able to run it under the injecter harness and make a ghetto bracket to make it work for now. is dohc longer?

I would think so. Here's a pic of mine installed. PLENTY o slack, I would imagine it would work well for the SR install

David BMar 10, 2010, 4:03 am · #1266

yea my shit is almost STRETCHED across. lol. but i dont need to go to the yard soon, so this should be fine for now

David BMar 10, 2010, 5:04 am · #1267

heres goes the wiring ideas. like i stated, im making my own chassis harness to run the motor, due to my stock harness falling apart and catching on fire a few times

this car is for track use, im not using wipers, or windows, or radios and shit. so dont lecture me please

all the plugs are now inside the car, for the chassis so dont mind the pics if there outide the car

i need to find out, which 12 volt power goes where, and what do i do? hook a multimeter up when im done add ecu power and figure out which fuse i need per wire?

so here, from the battery. its gonna T off from the battery post, one side for switched stuff like, lights, fuel pump, E fans, and then the one side for motor. ill be fusing both power guaged wires wires and on the headlight/switches side ill be using the switches on the ground side, and also using a similar distribution block to fuse them

i figure this should be sorta ka related

MOTOR SIDE

---------------------------------------------------------------------------------------
1.
from battery, where its gonna be ted off
(http://i367.photobucket.com/albums/oo119/whatrwedoingnow/105_4112.jpg)

---------------------------------------------------------------------------------------
2.
to here, on this distribution block, the old connecter that goes to the starter from the motor harness will connect, which goes back to the battery as shown before

i might be using 2 of these on this motor side

(http://i367.photobucket.com/albums/oo119/whatrwedoingnow/105_4113.jpg)

---------------------------------------------------------------------------------------
3.

plug from the ecu (ill edit later when i figure out which is which)
(http://i367.photobucket.com/albums/oo119/whatrwedoingnow/105_4114.jpg)

---------------------------------------------------------------------------------------
4.
plugs from the motor harness, that used to plug in where the s13's battery was, they plgu into the chassis harness. isnt this the spot, where my main functions will be??
(http://i367.photobucket.com/albums/oo119/whatrwedoingnow/105_4115.jpg)

---------------------------------------------------------------------------------------
5.
new problem, these 3 plugs. look like they come from the lower motor harness, do they have to do with the trans speed sensors, i dont mean the literal sensors off the trans, but are these from the signals they send? or oil pressure? or anything important ecu related. that i might have to manually tap into a ecu pin? will i need to use these? will i need a auto ecu to bypass them? are these the wrong plugs im talking about?
(http://i367.photobucket.com/albums/oo119/whatrwedoingnow/105_4116.jpg)

if its just for the oil pressure and water temp etc. i dont care, ill be putting aftermarket ones on,

so does this seem possible? i understand ill have to wire my own push start (which i have a heavy solenoid to use) etc. but that still is in the distance from where im at now

David BMar 10, 2010, 9:28 pm · #1268

anyone?

mod_mastazMar 11, 2010, 3:33 am · #1269

#3 is the ECU to dash plug. You can get the water temp signal from there. Oh and also cold start signal wire goes here too.

#4 is the ECU power(gray) and signal wires(brown) The gray is for the ECU power, ignitor, o2, etc. The Brown is for the sensors, like AC idle bump, PS idle bump, and whatever else your SR20 is supposed to be equipped with.

#5 is the lower harness, which is for the starter power/switch, oil pressure gauge, alternator power and signal, and transmission switch sensors. It should be really easy to figure out.

David BMar 11, 2010, 5:15 am · #1270

5 isnt the lower harness... i have the lower harness hooked up?? i thought

mod_mastazMar 11, 2010, 5:20 am · #1271

Hmm. they aren't with your lower harness? It could be your neutral safety switch and reverse lamp switch. I'm not too sure anymore. Where is it coming from?

IggyEGuanaMar 11, 2010, 5:44 am · #1272

east coast style wins again

IggyEGuanaMar 15, 2010, 6:17 am · #1273

all compliments man.  all compliments and I'm jealous of what u guys have out there.  except the weather

I'm jealous of your weather.... You have milder winters, and hurricanes. Very jealous of VA

No joke

jealous!? you live in vegas!?

and your towards california, and all the cool people drift stuff. and hella flush homies

here, theres like, a slow build of drifting, slowly growing and getting bigger. and 2 east coast s12 drifters. and lots of rust and rain. and lots of mad tyte civix
brewster240Mar 16, 2010, 2:31 am · #1276

what about zack??? i just saw him yesterday lol
PraizewoodMar 16, 2010, 3:51 am · #1278

Great to see ur still alive. Just linked a guy your drift videos today because he didn't believe ca20 could dorifto

sam31183Mar 16, 2010, 5:23 am · #1279

most of davids drifting was done with a sohc ka though.

Don't be complaining! You realize I live in MONTANA!!!! The only people with anything but riced out civic's are a few of my friends with S13's and S14's! No drift events. Some weird little SCCA events and that's it. So be happy for what you got!    And it snow's a lot so i barely get to drive the S12 in the winter!  

But still. I'm excited to see the SR going in your car!
David BMar 16, 2010, 10:34 pm · #1281

these turbo lines are confusing the shit out of me

David BMar 19, 2010, 10:40 pm · #1283

update!

bought some cut steering knuckles from 180sx alan! they will be in soon

okayy, tying things up, picked up some parts

spare fender, driveshaft, headlight cover (mine is dented), mk2 grill and marker light assembly

getting very close to startup

RedneckMar 19, 2010, 11:10 pm · #1284

Good to see you should have it up and running for drift season. For a second there I was getting a little worried .

IggyEGuanaMar 20, 2010, 1:05 am · #1285

even with the IC bein pretty hugh and the piping being what it is I gotta say ur mid mount setup is not too bad.  Possible to rotate the compressor outlet to point towards the front of the car?  Not sure if it'll hit anything but should make the piping shorter if it fits.

David BMar 20, 2010, 4:56 am · #1286

maybe iunoo. ill look at it later.

id rather get a midmount i/c and do that too. but for now that peice was already like that, i just added 2 bends

David BMar 22, 2010, 7:55 pm · #1287

i have spark out of every spark plug, and fuel squirting out of all the injecters.

could my old gas be causing this? maybe the maf is broken since the wreck. iuno

David BMar 22, 2010, 8:47 pm · #1288

BAM. video up soon

LeegamerMar 22, 2010, 8:49 pm · #1289

heres the video, its running kinda weird. has a intake leak or two i think. but who cares, for now its on!

it runs better when i disconnect the neg terminal on the battery while its on. hmm

Phisherman09Mar 23, 2010, 1:53 am · #1292

good shit.

brewster240Mar 23, 2010, 1:56 am · #1293

very good david.

put the black box back on though, none of that running a hose from the vc back into the block!!

Blue84coupeMar 23, 2010, 3:01 am · #1294

Nice!

Now get it all buttoned up and get some drift footage!

kyskaterMar 23, 2010, 4:30 am · #1295

david u really need to sell me those front wheels

it records audio and data just before impact
200sxkitcarMar 23, 2010, 6:10 am · #1298

congrats on getting it running!

some info on the wiring.  you must already know some of it tho

(http://i367.photobucket.com/albums/oo119/whatrwedoingnow/105_4114.jpg)
The SR start signal should be the orange wire if its the same as the KAs.

(http://i367.photobucket.com/albums/oo119/whatrwedoingnow/105_4115.jpg)
main EFI connections, you must have already made these...if its like the KA, black/yellow=power for air regulator, black/white=ECU power when key on, red=power all the time, black/red=thicker power wire for coil and injectors, and apparently there is a brown wire 12v for the o2 sensor.... read http://www.frsport.com/SR20DET-Swap-Engine...-SR20_t_26.html (http://www.frsport.com/SR20DET-Swap-Engine-Harness-Wiring-Diagram-Guide-SR-SR20_t_26.html) for more detail....

(http://i367.photobucket.com/albums/oo119/whatrwedoingnow/105_4116.jpg)

the fat two prong connector is the connection for the alternator.  Im assuming youre running the SR lower harness, but basically there needs to be a fat power wire running to the isolated stud (look for the plastic insulation) on the alterator, thats where one of the wires in this connector runs to.  the other wire is for the field control, there should be a two terminal plug that actually clips in to the alternator. One terminal should have a fat wire and the other terminal is probably a yellow/red or white/red smaller wire.  Reality is that these two wires just splice together later down the line, so you can run a nice piece of wire between the two and run a fused connection directly to the battery.  use a fusible link or something like a megafuse just in case something happens.  its a bit hard to explain, i can take some pics or something if you want some clarification....

those other two connectors arent necessary unless you want backup lights.

David BMar 23, 2010, 3:09 pm · #1299

thanks sterling. ill be looking into it

http://www.youtube.com/watch?v=17zkV2RZ16o (http://www.youtube.com/watch?v=17zkV2RZ16o)

i figured it out, the CAS was set to all wack. so i pulled the vc and reset it to stock,

dude its so fast! it spins the 235 r15's like there nothing!

David BMar 23, 2010, 5:20 pm · #1300

i tried to do a small takeoff video but i cant hold the camera steer and shift. when i drop the clutch in second gear it just spins  haha, here. i shifted second to 5th by accident at the end. im not used to it and its too exciting
