TD05 Turbo

Hey guys, i have just got my hands on an evo3 td05 turbo, i have also completly overhauled my engine, ported the head as well, now the thing is that to fit the turbo is not the problem, i got an adapter made for it, but the problem comes with the exhaust side of it, it comes in the way of the dipstick and the oil cooler lines as well as the oil filter, can you guys please help me out with what i should do. has anyone done this that can help me out by giving me pics or anything please? there is a track that i plan to participate in provided my car gets done. i got a jdm st 185, planning to boost it to 20psi, got a 3'' exhaust, dual friction clutch. would i be able to beat a subie sti wrx 98? what if i just put in the ct26 jdm, which is ceramic coated, what would be the difference in power compared to the td05? sorry for the ultra long post, but any help would be very much appreciated!

What do you plan of using to keep you engine safe at 20psi?
Are you just running a exhaust and turbo?
