In many ways i agree with about bolt ons, not just also speaking as an Tuner frum Asia. Internal werk is needed if yu want big boosts. Sure yu have headres and intakes and exhaust systems. Power can be made by one revising the intake, taking out the secondaries, that will easilly give yu a 6-8 hp bump, but that requires taking the intake off(92-00 models only apply)Or new cams, raising the cmpression, pistons, which yes take money. So turbo seems to be the easy solution...or is it. For the price to go turbo yu can easilly build up an H22A JDM or B18B/C engine that will stand the test of time.For the price of most turbo kits yu can get Piston and ring set(high comp) lighter rods, a block brace if yu are usung a non decked block. cams, rod and main bearing and a whole lot of goodies and come out a little cheaper and have less hastle, then after finally getting the turbo on all the adjusting and tweaking of getting it drivable so yu dont blow the engine on the test drive??? Dont yu think
