checking out an 86 mk3 tomorrow

[cre]

The hose comes from the hardpipe assembly under the lower intake plenum around cylinder #5 and #6.... a bitch for me to reach, but I imagine if you've got skinny arms you may be able to pull it off... could try from below too.

is this the same hose? cause i have #16267 going to that small intake sensor

[cvbikeguy]

oh wait they are different hoses. so then where does the AIC come from/go to?

[cre]

Here's how it runs:
#16267 runs up to the back side of the TB (to the nipple you have pointed out)
Then, from the front nipple of the TB the hose runs to the Idle Speed Control Valve (ISC or ISCV for short)
Then the coolant exits the ISCV via a lower hose which runs to a nipple built into the flange of the lower intake plenum around cylinder #2 (it is on the bottom side of the flange)



And YUP, coolant to the throttle body... it's to prevent ice from forming inside the TB and ISCV (yes, it's really possible; even on a warm day).

lol sorry for posting a million times in a row. this car stuff is frustrating. i hope the r154 swap is ALOT easier.

thanks cre. i want this this running tonight hopefully

crap i cant find the nipple on the flange.....

[cre]

It's on the flange of the lower plenum or runner which bolts to the block... I actually left the hose attached when I pulled that runner. Heh, is the hose already attached?

i couldnt sleep at all. i felt so defeated that i couldnt find that stupid nipple. tossed and turned.

i had to look again

i stare at the car for a sec, not even reaching in.

took a breath....

reached in

within a second i found myself touching the nipple.

WTF

anyways so thats that. just need one more hose to go to the backside of the throttle body. gonna turn the key tomorrow and cross our fingers.

oh one question. how much pressure goes through the coolant areas? heres a pic. and yes cre i will have a finish paint job..... just remembered the lady forgot to paint the hood.............






feel like i still dont know anything about cars...... cause i dont.

so im pretty excited. now i probably wont be able to sleep since i know that im so close to getting this car started. learned a lot of things on the way also.

1. so not worth all this effort on a N/A
2. label more, take better pics
3. never do this to an N/A
4. dont break sh*t
5. just get a turbo engine and rebuild that
6. get a punching bag
7. your lucky after going through this that you arent in danger of substance abuse.

so yea. waste of money, yes. waste of effort, yes. me being a newb and actually learning something, maybe. this car may not be fast of a turbo but i really cant wait to drive it. sure as hell faster than my 4 runner and even though its wingless, the body style of these supras are f'ing amazing.

I'm pretty sure the stock radiator cap is SUPPOSED to open at 13psi. I recomend testing them periodically, even new ones can be way off.

Well, at least it'll keep you cautious and you know a lot more now than you did at the beginning!

1. sure it's worth it... peace of mind? Worth a fortune to me. Besides, it was a great lesson. (you DID remember to chase the bolt holes in the block with a tap... right?)
2. plastic baggies, masking tape and a marker.
3. why the hell not?'
4. agreed!
5. yeah, but if you need a car in the interim shouldn't it be running?
6. mmmmkay, whatever you need.... I needed a case of Kleenex.
7. Nah, there's enough chemicals floating around while doing this job that it'd make the drugs seem week and not worth the time.

No and no. It may be a bit faster, it's not uncommon to find that we've fixed a number of other problems on the way.... won't be more powerful than stock, but you might be surprised to find it was running like ass before; Happens often.


What's wrong with wingless? The OEM wing is just a "make pretty" part, no major effect on the vehicle's aerodynamics.
