The B chassis guys have been using these for a while, haven't seen them used on a C4 yet but I have a set on the bench. Lined them up with the stock mounts and they look like they'll fit nicely...might require some slight modification.

Note that you'll want to shield the passenger side to prevent it from melting.

Ed, you seem so skeptical of these ;) Considering the OEM and 034 mounts are all marketed as being universal for 5cyl apps I can't imagine they wouldn't fit. There's pics somewhere in my project thread of them mounted up, I just used a dremel to make the holes a little bit ovaled away from the center of the mounts and 5min later they fit perfect!

Yeah all the mounts are the same, surprisingly I had just never seen anyone use them on the C4...maybe I'll be the first :)

You guys are like hocus pocus with your mounts and untried products haha!

Obi won't even try my home made mounts for free! Oh well - I have some sweet hock puck mounts with Grad10 Hardware and rubber bushies to decrease vibration...

Maybe I'll have to show everyone rubber is rubber... poly is poly....

What do you mean by that? There are many durometers of each, not the same at all.

Never said I wouldn't... just that C4 folks haven't really dabbled with different options... Matter of fact, Lets meet today so I can take a look at these homemade contraptions of yours... :lol:

Yikes... someone not test the tolerances on the thrust bearings on the crank?

Nah, I just tried to run more than the recommended 165 ft/lbs of torque at the flywheel per rod that is recommended by Scat for this particular rod.

Those where an H profile, right? What are my I profile rods rated at?

Looking to piece together a little Side Mount fluid cooling section for my car, similar to the one AutoSpeed version
Image
Image
Image

Possibly with some sort of ducting to the oil side...
Image

The Question is, do we NEED to oversize it over 3x over the stock 7row in order to keep things in check on hot days with spirited driving?
25-Row
Image

19-Row

You need to consider the entire size of the core not just the height

For example a short core can have the same cooling capacity as a taller one. OE oil cooler is much thicker

WxHxD
10x10x1=100in3
10x5x2=100in3
5x5x4=100in3

I would fit as large of a core as you can for the oil cooler.

Splitting hairs but I'd think that more rows/in³ would be the more efficient.

Anyone have clue what these extra gaskets go to?

More surface area exposed to cooler air, also agree with the hair splitting :D



Medium one looks like a tstat oring...

Small one looks to be the size of the water manifold orings (three of em though...and I've only seen those in yellow, so I'm not sure)?

Large one may be for the water pump?

They were in with the oil pick up gasket and O-Ring... I'll confirm in the morning once I get back at it...

Good insurance on that cooler - the extra surface area should help. Where did you purchase it from?

Haven't purchased any yet, but I found a Setrab unit local to you actually (Lynn) that I'm checking out this morning....

Hadn't unpacked the turbo since it came weeks ago... Sort of needed to do it as my fabricator needed it to ensure proper fitment of vBand flanges...

Confirmed that the green one is for the oil filter housing bolt... The other 2 in the above pic are indeed for t-stat housing and water pump...

Still got a few more to go... I've got the green gaskets already in the right places... But the other ones are still in question... As I go along it may become clear where they go, but I don't wanna go so far to have to undo it all again for 1 overlooked seal...

How about AAN exhaust cam on the intake side paired with 7a exhaust side?

That will work just fine, but the most gains are with both 7A intake/exhaust

Use 7a exhaust on both :) Some machining/degreeing required.
