4.0L rebuild - other things to add?
#16
#17
I added over 100hp+ to a 993 and upgraded the brakes to big reds. Only saw a difference at the end of long straights on the track were I could really brake late. In my opinion standard Porsche brakes will be more the adequate.

I'm not sure on the OP's situation but I know a FSI build will have a 160T and new oil heat exchanger. You can also add a third radiator and auxiliary oil cooler if you don't already have one.

About adding and oil cooler...... wouldn't that make morning warmups of an everyday driver a bit of an issue? I for one, wouldn't want to sit in my driveway or at least not take it over 4K RPMs for twenty minutes while that oil took forever to warm up.

I already have big reds and no intention of dong anything there
Thanks

Vern1 looks like you have the bases covered....same with Spiffy. As you both know I added the IPD Comp plenum and GT3 TB on top (stock air box) with X51 headers, 200 cell cats and Fisters. Both of you guys are in a for a shocker (in a good way) when you get your car back.
My slope keeps getting slipperier......I found a X51 intake and plenum off a Cup car. They are both alum and welded together. My car is currently back at FSI getting mated with the X51 intake / plenum, carillo pistons and the heads are being ported. This should give her a little more snap I'll start a separate thread as not to hijack this when photos are available.

Looks like I am about to pull the trigger on the IPD and TB. That will leave the headers and cats to source. I may have all the parts before the engine even gets to LN which will make the wait so much longer
Hopefully I don't find too many other things I "need" to add.

A few sources, including Sharkwerks, who make substantial mods and sell many parts, and can sell headers, claim that said headers are not worth replacing and no real gains come from aftermarket headers. The stock ones flow right.
Cats are the main choke point.

I added headers and would call the stock ones an exhaust manifold and not headers. They are much different in design. I have before and after dynos but there are multiple changes so there is no way to determine what the contribution of each component if any. You may be correct that headers do not offer any gain but the guy who did my dyno tune thought it was to best exhaust mod to do in terms of performance. I really don't know. I had fun installing them!

However, many seem to have had good success on this combo of intake/exhaust mods and it seems like the right way to go to me to accompany the 4L bore
so true, so true
