Heh you remind me of me a month ago
. Where to start. First off you don't want to waste money on porting and/or polishing your supercharger. Read posts all over this forum about that. I was thinking about replacing my injectors too until I found out they're theoretically rated to handle 542hp. A more practical 460hp was placed on them according to their flow rates so I just sent mine off to Injector.com for a good cleaning and balancing. The fuel system in these cars is amazing and its doubtful anything you have planned will push them too far. Doesn't you SSEI have a trans cooler? Transfer that joker. Also your stock SSEI radiator has an oil cooler in it so you might reconsider replacing it, it should do a good job of keeping your engine cold. Hell I kept mine at 160deg by tapping the fans every so often if I sit still long enough. GMpartsdirect.com offers a rebuild gasket set that comes with about everything you need. You can get plenty of OEM parts pretty cheap through them. Your going pretty heavy on your HP figures with what you've listed. I have the Jet stage 2 chip also and got to drive with it for a few weeks before I pulled the engine. Its more of a smooth acceleration than a huge increase. I'm sure they would tell you something in the 7-13hp range. The smaller pulley really puts the HP lower in the range and spreads out your power over the bottom end of your rpm range. The end boost will be higher resulting in more HP but you still won't be in the 300+hp range. Looking at prices locally (unless you do it yourself) your looking at port jobs of $250-400 for the heads $150-200 for intake, $120 for rebuild gasket set, $100 for smaller pulley, and $200 for Stage 2 chip. Larger fuel injectors (for 300+ hp
) are in the 48lb/hr range and about $60-70 each for some good ones. Then add in the radiator your talking about and your well over your $1000 limit. Don't take offence but on your budget I'd go with a good rebuild and a handful of budget performance parts. Stage 2 chip, pulley, maybe a home made CAI and a couple other hp tricks you can learn about in here. Maybe you can pull some strings locally and get your porting done a lot cheaper but thats what I'm looking at in my area. On to the throttle body...There is two things I know about the TB. You can use a '94 TB on a '93 but this has had several problems, most caused by some @$$ named Floz. Your TB is really tuned exactly for your engine and replacing it with a TB from another year (so far) has caused a lot of problems. There is one guy I know of that uses a later year TB but he says you need to mix and match different gaskets and it won't do you any good anyway since your sc inlet is so small. Meaning you would have to go with a later year SC too. If your not in a hurry I'd set it to the side until I get more info on where we can get performance parts. I'm not sure about the brakes but on the lightening note something to consider. On an "average" setup 100lbs equals 0.1sec in the 1/4 mile. Is it worth it to have your car look like junk and be missing an Air bag? Which I'm sure will set off all kinds of alarms and codes. I guess it really depends on what you have planned for it and hell to each their own. Lemme know if you have any more q'*.
