The headgasket is cheap enough where I wouldn't even bother re-using. Yes its more money "down the drain" but like you said peace of mind goes a long long way. And I need every bit of that for my car as I almost hate driving it with how nervous I get about it breaking.

The headstuds could maybe be re-used I know, but re-torquing them for a 3rd time (i have had these on the last two motors) just seems like too much, especially with how much boost I ran before on the car. I already bought the newer ARP's too so its too late now, but they are the new ones and I was always skeptical of the standard ARP's. I think these are more like the L19's or whatever all the 4G63 guys run.

Reusing headstuds and headgaskets is just asking for a failure. Smart move getting everything new!

Well MAP should be finishing the head reinstall tomorrow, should be done in the morning I think or early afternoon.

Looks like the car was leaking in several spots. Oil feed to the turbo, banjo fitting to the oil cooler and the timing cover were all leaking. They are making sure the motor is perfectly sealed up before they tell me its done. Feels good to know it will all be fixed when I get it back.

They also changed my tcase and rear diff fluid so now I am pretty much all ready for the summer, just need to keep fiddling with the tune to dial it all in.

Nice, hopefully I'll get to see it on the roads more!

Well got the car back yesterday. Here is a list of all they fixed/replaced.

Cosworth Headgasket (90mm bore, 1.3mm thick)
New ARP Headstuds (625+ ones)
New revision "beefy" timing chain from Mitsu so no chain stretch
Change Tcase fluid
Change rear diff fluid
Valve cover gasket
Water pump gaskets
Oil Cooler crush washers
Thermostat housing
Oil drain o ring
Front main seal

So lots of fixes for gaskets/seals, should be nice and sealed up now hopefully :)

Last night I drove it to Wisconsin to drop off Knoxville's G8 for his cam, ported head and torque converter install out in the boonies of WI. So after 200miles the car seems to be running pretty good. (Trying to get knoxville to start a build thread here just for fun, they got his motor out so damn fast, I want an LS motor, seems so easy).

I don't know how to get over it but i feel like I always hear sounds and I am not sure if I do or not. I think I need someone else to drive it for a while to see if it sounds normal lol.

Regardless, I did some gopro testing tonight on the car and tried to scale my injectors down for real E85 more. Well the gopro still has dumb loud wind noise, I tried some fabric to cut down noise (aka cut up sock :)) that didn't work. Also I had to let off the throttle at 7500rpms as it is around 13.0 at WOT. No more WOT for me...need retune I thinks.

However, my cruise LTFT is +5% and idle LTFT is +1% so my changes seem to be working :) I am going to be stopping at MAP next week to double check all the leaks are gone.

More to come over the next week or two..I have a lot of work to get it ready for MAP's event, still not sure if I will make it honestly. I am not going unless I am 100% confident the car will run correctly, even if its on a low power tune, I don't need full power to have fun, just working right.

someone add a tag?

Nice man, you might be at the point where you will never feel confident driving the car I know with one of my old cars I was that way and was glad it was gone even though a year later it was someone's DD and was problem free.

I'll drive it! I'm local and usually home (but doing homework) but I'll take a nice break. Also you should try to have someone else drive the car while you tune if you can it might make it a lot easier on you to spot any little things that could be effecting the tune.

Good luck man 200 mile drive is good progress.

Nice, but as for thinking you hear a noise, yeah I don't think you'll ever get over that. That's how we all are. Wasn't there a video someone posted, specifically aimed towards evo owners about that ("do you smell that? did you hear that?")?

[scheides]

Sweet! Is the cossie gasket extra thick or something--why it over OEM? Just curious.

Lots of good fixes there, hopefully your leaks are all gone! good wok sir, you now have me worried about my stupid timing chain....something to think about down the road I guess.

You get over it.

[Halon]

You get over it.

Not me, I'm still the same way.
