Edit: Fuel pumps are a MUST when going KAT. Read Jeff's post below this one for more info.

Hacked MAF is also a good option that requires NO ECU mods or piggyback fuel systems. All you do is stick your maf sensor element in a larger tube (size depending on injector/turbo size). a good size to use with 370's is ~2.6ID tube when running 250rwhp or below. some people have run up to a 3"ID with higher numbers.

Starion Intercoolers are also a good option. relatively efficient and good size. good to 300rwhp from what i've heard.

Z31 turbos are a T3, but difficult to fit due to the turbo elbow. not recommended for top mount manifolds.

oil feed line from the turbo can come from 2 places. a sandwich plate between the block and oil filter or the more common, oil pressure sender location, right below the oil filter. thread pitch is 1/8" BSPT. 1/8" NPT will work but will more often than not strip out the hole. then you are FUXORED! so don't use NPT thread pitch on the block. Only problem with BSPT is finding it stateside. America, being the geniuses we are decided to make up our own thread pitch, and not use the world's standard (BSPT). sound familiar?.... not using metric system maybe? haha anyways. Also be careful with braided stainless oil feed lines, they are the best for the job, but you can put holes in them relatively easy. I routed mine back behind the engine because I thought over the valvecover was ugly. it looked better, but got snagged on something and got a hole in it. luckily I was almost home when it happened, if I had been driving for another 5 mins my engine would have been toast.

One of the biggest bitches of everything I did was welding in the oil drain fitting to my oil pan. well not the welding itself, that was the easiest part. taking off the oil pan and especially putting it back on SUCKS!!!! set aside a full day to do it.

another good thing to do is buy a high flow cat for your kat. it seems to be one of the most overlooked parts of a kat setup. Summit sells a universal DOT approved one for like $53 shipped, very good quality. I've got one and love it.

that's about all of the random shit I can think of right now.

I know I'm prolly not supposed to do this but....... [No. You were right. You're not supposed to do that. ~Jeff]
