ALex, from your intended usage as specified, you will benefit from dry sumping, no question, especially with an 82 stroke.you will also pick up some power, i recon 4/5 hp at high revs, at least over normal wet sump. my experiance is mostly T1, and Wasserboxer, but the same applies to T4.
most pumps fit in the case simply with the longer fittings supplied, its important to plug the case port to avoid back feed pressure losses, the pump ports are non existent.
i would go with the autocraft pump, as its the one with the most good feedback, quality counts with the engines heart. i have no knowledge or feed back for the CSP pump.
I use an ARPM pump, its superb quality as you would expect with Lowry's name on it, and has hundreds of hours on it and its still like new, tho i doubt you would find one for sale these days, check its drive keys and gears for wear if you find one.
the system will also help your weight distribution with a front mounted tank and the oil content.
use 5/8 pipes, possibly even 3/4 for the pump supply line from the tank.
coolers work well on this line, rather than on the pressure side, altho' many do use the pressure side for coolers.
you can run the car lower as you wont need any sump extensions, altho T4 is better in this respect, they're are band aid anyway in my view. as regards accusump, more band aid, wev'e had engine disasters with these, two seperate engine failures recently, they cannot compensate for surge and oil leaks as dry sump can, o.k you can run out of oil with dry sump, but you have huge reserve, if you need anything other than the stock system, then it HAS to be drysumping
no doubt more advice will be up soon, hope this helps..... ps i know where there are several used accusumps for sale...
