so far mines been holding up pretty fine and according to evo scan im hitting 12-13psi

 

Wow i just noticed u have about 25 in/ vac. I only have like 20 when fully warm at idle. i must have a vac leak? when im driving and let off the gas i only have 22 vac

 

Mine stays right at 20 vac at idle too.

 

i think mine is the same between 20-25 the vac in the vid was me on the freeway cruising then slowly accelerating, i do remember there was a time my idle vac was about 30 for a while lol

 

Where is ur boost gauge hooked up to??!

 

you should see 18-22 vac. Anything Under 18..(so 0-18) would be a vac leak... ur fine.. that pic looks like holding 21/22.

 

Thats link's pic not mine, at cold start im at like 17-18 vac and then when it wars up it sits at like 20 vac, and when i let off the gas to decel it reads 22 vac

 

the fpr vac nipple on the intake manifold

 

ya that sounds about normal to me...

my car idles at about 3in-Hg cruising im around 12in-Hg. and decel at 22in-Hg.

ive searchd n searchd for my vac leak, and cant find it (im 99% sure i know where it is, just havent fixxed it) its obviousely big, but i cant hear it, even in boost i cant hear it.

its my #1 prioity to fix once we start seeing 45+ degree weather again..

 

Dude thats a HUGE vac leak

 

well ya.. but seriously.. i should be able to hear it.. ill be tearing everything apart in a week or two (once its warms up enough to go outside with a tshirt on, and im fat, so thats still pretty cold)
when i have it all torn down, ill be replacing all the gaskets, checking and shortening all my lines.. and reconnecting everything, Again......

 

How much timing is enough timing? Im currently at 10* advanced in boost with absolutly no knocking issues at all on 93 octane fuel and 11.2-11.5 AFR in boost WOT. I think i can still advance the timing, but im nervous because i dont want to break a rod or something, if i keep increasing my timing, does my chance of snaping a rod at 6-8 PSI drastically rise? I know i can rise it more, one time i was at 12 timing advanced no problem but i got nervous so i brought it back down to 10* Any input on this?

 

You want to increase timing until you stop seeing HP gains. Without a dyno, this is likely impossible. Also, it's not just increase in timing that breaks rods, it's too much torque/cylinder pressure. Knock hurts the engine, and typically it occurs before the MBT is reached, which would probably mean you could increase more....but I wouldn't. I would do some pulls, and graph HP (which is hard since you're an auto), but I know this. If you just use some random arbitrary numbers, and compare them from one pull to the next, it won't tell you anything meaningful to compare with other people's cars....but it will give you something to benchmark yourself against.

 

Gotcha, cuz yeah like after even increasing the timing by 2 degrees i can literally feel the difference in the pull! But i see what your saying, and ill need to figure out how to graph pulls somehow, hmmm..

 

So, recently i started smelling coolant under the hood! Looked closer and noticed the turbo was hitting the water pipe inlet :-O I think its cracked, its all wet around that area! if anyone has the WATER INLET PIPE please let me knwo ASAP its only going to get bigger, my cost on it from mitsu was 84.00, i know some one has to have this!

When i get a new one, should i bang in the pipe a little in the area the turbo is so it wont touch it next time? The turbo is fully grinded down so i dont think i can grind the turbo to notch it anymore. Here is a pic of the pipe that cracked.
