Read about your breather problem. I use S60R breather with 25mm (1") line to under the car. No crankcase pressure problems even on 660hp / 660nm / 2.5bar / 8000rpm rev limit.

Also i have oil restrictor on my holset hx40 which is 2.5mm (0.100"). Also use 1liter less oil in engine so oil level should be on halfway mark on you oil dipstick. :) Also revving only to 8000rpm is helping alot compared to 9000rpm...

Good to know 'm not the only one running under full oil capacity :D

Good idea to increase the box vent to 1".

I haven't had breather issues with my current build (25K miles now), however since I have the setup developed & working I didn't see any reason to remove it, even if it is fairly complex.

I tried to put a S60R breather but it does not fit on the early models. How or what did you use to add the 1" vent? More pictures?

Until he responds - you can drill & tap the fibre housing - I used 3/8" NPT (drilled out to 5/8 ID) for my cam vent - you could easily tap it out to 1/2" NPT or larger & fit an elbow.

I use the same box - under a stock manifold you need the IPD phenolic spacer, and move the cam vent back as shown in my pic. Don't forget to buy the can vent hose also - it's a different shape since the port location does not match the old style- cam vent is rotated around to left side VS. Right side in old style

Instead of external cap for the old outlet, cut it down and tap & insert a plug (3/8 NPT), since that is the area where you will hit the manifold underside.

What type of rad do you have? There is no reason a larger expansion tank would be required - there is no change in expansion rate of the coolant... I am using Evans Waterless since last August, but didn't see any increase in coolant expansion in the reservoir with the 3" core and standard coolant prior to that...

Trimmed up the quote a bit.

Since the volume of fluid has increased the volume of expansion also increases. I didn't measure the fill volume so I don't know how much I added, but I think it's 10-20% more with the torque converter cooler no longer required (MT swap) as well as the increased core depth, by about inch/2.

If you haven't had any issues it makes me curious if I'm having a different cooling issue. I assume the PN on the reservoir is common between MT/AT.

Reservoir is the same either way - I'm using the '99-on unit - and my system holds substantially more than stock with the full 3" core vs. stock 1.25" unit. I keep my reservoir about an inch below the full marker, and once hot, it is level at the full marker.

You should think about blacking out the front pilars completely ala Range Rover Evoque.

Having said that, the car looks amazing!

does the fact that the pcv box is bigger help in general? i'm having more pcv smoke problems i like how that 1"vent it straight down

If you have a N block - it has no windows between the cylinders, and with a stock box you are more likely to develop positive pressure. If you are VTA, using stock size outlets, it's just too small. The larger box helps, and having an outlet of 1" (2x stock) should allow for unrestricted blowby passage.
