Thread: LIM Gasket Replacement. what else while I'm here

Just picked up an 02 GTP 40th anniversary Coupe with 160k km's on it. Only aftermarket part is a K&N cold air kit, however it also the includes the ever popular "dreaded" leaking intake option.

Got it for a deal because of the intake leak. (no milkshaking in the oil either) I've done the repair 3 or 4 times so it shouldn't be an issue. Just wondering what everyone else would replace while were opening her up.

My list is as follows.
-Lower intake manifold gasket
-Injector O-rings
-Supercharger (upper) manifold gasket
-Supercharger oil
-Valve cover gaskets
-both coolant elbows
-lower temp thermostat
-Spark plugs

Anything else while were down there? Thanks guys

i'd add some new vac tubing and T's to the list, as you know they will break on ya.


why a temp sensor? is it not working?

and make sure you have thread sealant on hand for the lim bolts.

sheeesh, i miss read you lol you can if you want, no real benefit's if your stock. and not tuned for it. the fans really should be tuned for it.

While your supercharger is off, change the coupler?? And yeah, if you are running stock, I would stick with the 195 stat. My thinking, and correct me or provide more insite, if your thermostat is open more often then closed, is it really allowing the coolant to absorb the heat from your motor? I'd buy a new tstat, just not a cooler one.

Corrected

Stock is a 195*, not a 180*.

180* is fine, stock or not. Seeing as you are up north, drill it so coolant is always flowing. Spark plug wires while you're there. Use the metal coolant elbows, for a few $ more they won't break. Don't forget a throttle body gasket as you might as well clean that while s/c is off engine.

Paint your SC and fuel rails while they are off also. If it has not been done, replace the fuel filter too, can't hurt.

H-Bar and no H-bar is same... Makes no difference. I'd leave it unless Intercooled. Biggest gain is just going to come from smoothing out the rough casting and cleaning the outlet side of the rotors on the case along with the enlarginging of the "V's" open end. You can look at my car thread, think I put some pics there, but there are plenty of pics and threads on porting the S/C. I agree as well, if time allows and willing to do it, clean it up and paint it, TB as well. Don't port the TB though unless you can tune for it.

As for the Thermostat, It's old school... Nice article and I didn't know it existed, lolz... But the other reason too is that even if the stat goes bad and stays shut, you'll have some flow.

If you want to go the 9's and do all good things to her, do a Tranny Pan drop and change the filter and fluid in there might as well. Lol

you could use vht caliper paint, not sure how broad there color choices will be.
