Julian's '91 200 20vt

[chaloux]

Go mls for sure. Worth it and they're cheap I thought... ~100 bucks. Do it once instead of do it over!

[PRY4SNO]

PRY4SNO, that movie is gonna be awesome when it comes out! Ill see it in theaters. Cool preview video on their website . That's a badass product though.

So I missed your point... they're already available. I have one at home, ready to install when I get my stroker from Hank.

And they're cheaper than TiAl/Turbosmart/etc, last I checked.

Ya I was just referring to their mission impossible-ISH video. high production value. Hmmm, I thought I read that mls requires a special head preparation or something. I'll look again on that.

[pilihp2]

MLS is the standard headgasket for the 20v. It's not an upgrade. So you're good there.

Okay, good! That's what I was thinking, but I wasn't certain. The original one is paper or whatever, but all the standard replacements (including the one from autohausaz) are MLS.

Thanks phil. yaaaah, I know the 20vt is paper but aren't the 20vt metal from the factory? I got down to the tricky ass turbo bolt (17 MM) and just need to slip timing belt off and coolant hoses. Now I need this crazy star bit for the old studs... Gotta look that up. No signs of detonation on plug ceramics at first glance. Fingers crossed here. I admit I didn't realize the stock gasket were mls per se but I knew they were metal, well the replacements anyway. Maybe mls is the only type of metal gasket produced cuz this is new ground to me. I will be flipping out in a good way if this goes well. I neglected to welcome you, Sven, to my thread . Its a little ugly at the moment.

The car is parked in the funeral home parking lot to be worked on. The boss came back to say happy birthday and I could tell she didn't want me working on it there but didn't want to say no because of it being a "special day" lol. I lost my birthday coupon for the ladies of the night over in little Italy. Try asking if they take credit some time.

So should I put the K26 with shaft play on from the old parts car 5k while I have both heads off?

Putting this up for a certain someone.

surface the head for best sealing with an MLS. You can get away with imperfections on a paper gasket but they don't hold up to increased power levels. Turn the power up on a stock 20vt and you'll blow it with ease.

The studs are a reverse torque. Same style ford uses for their cam caps on many of their 4-cylinder cars. Just go to Harbor Fright and get something cheap since I doubt you'll be using it much. Or just use a pair of vice grips and replace them with normal studs (8mm iirc)

[kieron_32v]

The standard head bolts are triple square not reverse torx. M12 xzn. Fat chance of getting vice grips in as the books are recessed into the head. $10 socket or hours of potentially fucking something? I know what I'd choose...

[88a5tq]

Birthday Beer!! this rolling rock has been hiding in my fridge since late 2013. Lunch... Right so 3 x 4 corners per a square seems legit. It's 12 points in the stud head. Maybe my mechanic friends have the bit

[88a5tq]

This look right> http://www.partsgeek.com/catalog/1991/a ... asket.html
Cheap... should be same one me thinks.

Thanks everyone for helping me out. Its been a rough 3 months.

Sven, what type of wrench did you use when you replaced the turbo to downpipe gasket?? I got the one pointing toward the starter barely loosened up and off after monkeying with a 15 mm wrench today. Of course before I found out it was 15 instead of 17 mm, I had already cut a 17 mm wrench in half lol. What a waste! did you use one of the half moon shaped box wrenches like this:

He said studs so I assumed exhaust studs. You really think I don't know the headbolts are a triple square design or that you couldnt get vice grips in there? I've done quite a few heads fyi. Forgive me for not reading "studs with crazy star design" as "stock headbolts"

[kieron_32v]

I didn't imply anything of the sort sir. Just stating the facts. Fwiw I've never seen exhaust studs like that on a 20v either.

[AngryTaco]

Just go to oreilly or napa, or whatever and ask for "triple square" tool pack. It's like $5 for 4. Comes with the size you need for your CV axles too.

[AngryTaco]

I have before, but whether they are factory or not beats me. Going off of the words 'studs' and 'star', I only assumed exhaust studs. Lot of domestic vehicles use that style with a reverse torque, especially Fords. I tried converting my studs over to a chevy style stud that had that design but it didnt work out the way I planned.

[PRY4SNO]

I found it pretty simple, if time consuming, to pull the starter and go upward from underneath to get at the bottom of the turbo area.

[loxxrider]

Having a boost controller which could be used for any engine or even for the same engine but with a different turbo setup is very difficult...

So, the Synchronic WG that I bought has a built in boost controller with 6 different settings.
http://www.synapseengineering.com/v4/wg/

I'd assume this is along the lines of what you're referring to?

It seems that the "built in boost controller" you're referring to is more like having six different spring settings. That would mean you can vary your base pressure, but it won't hold and control boost the same way a closed loop boost controller would. That's just like changing the gain to the mechanical closed loop control system that is the wastegate/turbo system. PID in VEMS is more like having a conroller control that mechanical controller, or cascade control.

What I mean is more like adaptive control. There are control schemes out there which are able to learn a system on their own with no user input and tune themselves. They can do it with only a few iterations too.

Jared, my fault, I used the wrong wording. your reputation precedes you here though lol. Especially when your project thread pictures show you working in a repair shop setting. these bolts are sure Purdy, hate to pitch en for ARP's... Well actually no I don't. They aren't even on the same level. PRY4SNO, when the mechanics replaced the clutch this last time they only tightened the DP bolt in question only slightly. I do think I'll take your advice upon installation though. Friend nearby may have the right bit. More updates to come.

Haha, to be honest, when I got to that part, I found that particular nut was missing. I was quite pleased, because it looked killer! The others came off fairly easily with a socket. From a performance standpoint, I'm not actually losing anything from a leak there (technically gaining, actually), and it had been sealing fine without it, so I just left it off, since I didn't have a replacement. No problems so far!

I want you all to know this. The person most likely responsible, who will not fix this because my flywheel ring gear is substandard (apparently he did no wrong because his actions broke a part that wouldn't have broken if it weren't for his f-up), let me know my terrible situation has prompted him to developed a 3d printed part to prevent him from doing this to anyone else in the future. He said I should be made to feel better because no one else will get utterly screwed by VEMS like this again. So I want everyone who needs an extra HO FET installed on their ECU, so they can run COP on their 3b, to send me a thank you card because I suffered a $950 lesson for them. MONEY, GET SOME!! I took one for a team that's yet to be assembled.

Yes, it would have. Those are complete shit and they break all the time for no reason. Nick had one break about 2 weeks ago just from cranking the car. Hank literally has a pile of broken ones.

I realize you're pissed, and the situation sucks, but the vendor is right. There would be no issues with the flywheel if it were a factory or other well-made part. There was a mistake made on your ECU, and I assume the ECU was promptly fixed free of charge, no?

Additionally, why would it cost you $950 to replace the ring gear? I assume there is nothing wrong with the rest of the flywheel.

$300 for hardware, $600 for labor (give or take $2), and $50 to replace the damaged-beyond-repair O2 sensor that I wouldn't even have needed if VEMS had opened their ears and converted my box to lsu 4.9 since I already had one.

[88a5tq]

Alternator went bad on my 5000 last night... No more running cars here lol

[PRY4SNO]

I haz spares LMK if you want
