Engine/Transmission (1994 - 1998) cracked manifold

[jbrowne]

Well it has finally happened to me. When checking the oil thes AM I noticed a crack in the exhaust manifold right in the middle on top, not spitting fumes yet but just a matter of time. Now I am thinking about the ATS three piece for the 1996 12 valve. How difficult is the job? What is the going price, manifols, gaskets, bolts, etc. Do they come drilled for a pyrometer probe? What are the do's and don'ts of tapping cast iron?

Drilling and tapping cast iron is easy. Use your old exhaust manifold as a template. PM me for details.

check out the guys at hytech turbo they sell an exhaust manifold it comes pre drilled for the pyro and i think it runs around $430 i am getting one tommarow and will be installing it tomarrow night if you want here is their web address www.htturbo.com ill let you know how hard it was when i get mine done

Comes assembled. My cup of tea.

When I put my ATS it was harder than everyone said it would be. I bolted the center section to the old manifold, then I hammered the outboard sections on one at a time using the flange face as a template. I stopped hammering when I was able bring them into alignment with a set of bolts. A fully assembled manifold would be much easier.

Mine went together pretty easy. Put the outer ends in the freezer. Center section was put on a spare tire in direct sunlight. Lots of anti-seize. Went surprisingly easy.

 

[jbrowne]

Now there is a great idea. It only takes a couple of thousandths. Did you pre assemble it then stick it on?

[bmoeller]

Yes I did. The freezer trick is one that I picked up from here. HIGHLY recommend it.



Used the stock manifold as a general guide. It was shrunk enough that it was off a fair amount. I loosely bolted the center section so I could start the bolts on the rest. I did have to pull it off once to make an adjustment. Drove it in a tad to far. After that, I put the gaskets in place and bolted it up. Had to use the rubber mallet to make a few corrections, but it didn't take much.

Do they still offer the ceramic pre-assembled unit?

 

[bmoeller]

Just looked at ATS's site. Anyone else see the price jump? Over $100. :--) $595 instead of $460.

Probably fuel cost surcharge. :-laf

 

[Andy Redmond]

Freeze the ends w liquid co2 (wear some gloves for safety and it should slip right together with a tap or two from the mallet). Hint a CO2 fire ext. would work. I have a 20 lb. CO2 cylinder that I test a/c expansion valves with. . No need to go this high end.



It will also chill a soda pop in a flash on a hot day. Oo.



If the manifold is coated use some sharp drills and take your time not to chip the coating or it might start flaking.



The coater that I use prefers that I drill and tap first, then have the ceramic "power coat" applied.

I asked them how they coat it without filling up the threads or did they chase it with a tap afterward, they grinned and replied "their secret" anyhow no one complains flaking coating.



Its a great mod and far better than stock.



Good luck

Actually is appears the opposite is true. They went down in price from $460 to $410. The $595 was for one that was ceramic coated and assembled.

High Tech turbo. Try theas guys. same as the ATS and cheaper. $425 + $35 for install kit.

Oh, you are right. I didn't read it that close. Was rushing a bit this morning.

I got mine from this guy on EbayFor $375 shipped, here is a link, http://cgi.ebay.com/ebaymotors/ws/e...&rd=1&item=7994612773&ssPageName=STRK:MEWA:IT, I called him on the phone with a credit card and had it two days later. brand new in the box. It was a good deal. ask for Kyle. This is their website. http://www.ftlbperformance.com/

They plug the hole when they spray it and remove the plug before they cure it.
