i dropped my A/C for the install as well.... made things much easier. OP, you will love it. i got mine from the group buy like a year ago and never looked back. still in great shape, coating has not even thought about flaking or anything. the hardest part about the install is the removing the old DP. the brackets that hold it to the block are GIANT PINTArses lol i had to move a bunch of stuff out of the way to break them loose, since i was doing it in my garage with no air tools. i also removed my radiator just as a CYA so i didnt put a hole through it. much easier to take 3 mins to pull the radiator then to have to buy a new one. i dont remember moving the dipstick at all, it cleared from what i remember, same with the A/C lines when i mounted my compressor back up. my install was on a JDM 94 WRC if that helps, so you can compare.
@ 2_Liter_Turbo..... idk why you would say for him to buy a different one. i have yet to see a better DP for a 3S. its not like a constantly research them tho lol mine is great, all welds are good quality, the heat coating is perfect, fitment was outstanding (except for that damn bracket that it comes with, took forever to figure out how it fit and to where lol) and it was for a bang up price. saved $100 from the normal price AND got is shipped to Japan!!! was pretty stocked about the free t-shirt i got too lol i just had to wear it when i did the install haha
OP, you got it, install it, LOVE IT!!!!! lol oh and that temp sensor in the DP is just to let the ECU know when there is a problem with the cat that is built into the DP..... no cat, no issue, no need for sensor, it doesnt even through a light or anything so no problem at all. 8)
