Better than a 991.1 GT3 choc engine I suppose. On the coolers it depends on use. I use do88 big pack which look identical to AMS but who knows what cores are in both - they're good for straight line drag racing over long distance (1.5 miles) but I expect with hard track use they're going to become heat soaked. Do88 do a set of intercoolers for the 991 GT2 RS. Maybe worth reaching out to them to see if they can fab up a set for 7 GT2? They're circa £8k-9k. By contrast the OEM 997 GT2 RS coolers are cheap and I've not seen anything vastly better for track use unless you go for super expensive aerospace or F1 cores from Marston or Secan. Something like £16k a set! To be honest if using on track and driving hard I would focus on a OEM tune like for the 997 GT2 RS as Porsches OEM tunes designed to hold onto the power in all conditions and just stick a pair of GT2 RS coolers on - they work.

I switched to a 996Cup clutch coupled with the Sachs 487 pp and its an amazing combo vastly superior to the GT2RS clutch allowing for much faster and more effortless shifts. Not really street friendly but a vast improvement on track. I also switched from the OEM GT2RS ICs to 4.0" Marston ICs and it's huge difference. Even at 720whp (+800bhp) the IATs stay in check during 30 min sessions at full boil. The OEM 7GT2RS ICs become a bottle neck at north of 600whp based on extensive Motec catalogs. Just something to consider for those looking to heavily track their GT2 at higher hp levels.

The car has a catless downpipes with Klein exhaust which plan on keeping. But im looking info as to keep or ditch the AMS intercoolers the car has. Ive read numerous threads about pros and cons of having the OE turbos matched to the larger core but.. I drive my cars and drive them hard, so not sure on to keep or not... the car has OE tune
Also now that I have the engine down I wanted to do the coolant plugs from BBI to be on the safe side, even thought the car has 28k km or around 18k miles, not sure if needed right now or which way to go as I worry about the originality of the car.

All advises are welcome!!!
