I just got done putting one in mine. There are only a few things you should need to concern yourself with:

1. Does a MY98 use a hotwire MAF sensor? Forgot if that year was speed density or not. If it does have a MAF you'll be getting rid of it (or at least not using it) and be mounting a MAP sensor instead. I went with a 3 bar but realized I'm never going to run more than 1 bar of boost (~15psi) so I'm left with less fine tuning on the load bars in the maps. If you're not going to exceed 15psi then get a 2 bar MAP sensor. Ask Haltech for the part # or get it from them when you order yours. If your car does have a MAP then I'm not sure if the Haltech will take its signal or not; it uses GM ones.

2. You need to mount a GM air temp sensor somewhere. I had a bung welded on my intercooler and threaded it on there. You could remove your manifold and tap that for the temp sensor if you really wanted to but it's a lot more work. Mine kinda balances out the look of the BOV on the opposite side of the intercooler

3. The coolant temp sensor is a pain. It's a 3/8NPT GM sensor going into a 12mm hole that the stock coolant sensor is filling. Hopefully the MY98 has a temp sender right next to the coolant sensor that provides the signal to the stock temp gauge on the dash so you won't lose that. Try finding a 3/8NPT to 12x1.5mm thread adapter. We had to make our own. You could tap the hole larger for the GM sensor right into your coolant line but takes a bit more work.

What's the rest of your set-up? I'll try to answer any other questions you've got while this is fresh in my mind.

well i've got a ludespeed kit still tring to source a intercoler maybe ill go front mont if i cant find a tmic, right now the kit is set up for 5 psi until i do a major rebuild thats what i will be runing,got all the gauges ,a/r , egt, fuel pressure,oil temp ,engine temp. i allready have a SAFC,maybe shoul just buy a J&S knock sensor and a ITC,what do you think?

I've always pushed for aftermarket engine management. If you really want to be serious about keeping that car running then you should get a new ECU. I had a J&S, ITC, and AFC running on my car earlier and it wreaked havoc on the MAF sensor. Likely you won't have that much trouble with yours since it isn't a hot-film MAF. Also the cost of the three aftermarket components I mentioned equal the cost of a Haltech. Since you already have the AFC then it's less of an issue. But you also have to consider the installation on these items as well. The J&S, ITC, and AFC are relatively easy to wire and pretty simple to tune. The Haltech takes a lot more knowledge to install and tune, but is a far better product in the end because of it. The Vishnu TEC-II kit is easier to install than the Haltech but a bit more pricey ($2500 as opposed to $1300). Each ECU has their pros and cons and I don't have the time to get into that now

As for a FMIC you must have some money to blow. Those are a bit more pricey and a lot more difficult to install. And unless you plan on running a lot of boost (like 15psi or better) then it isn't much better than a TMIC. You also have to protect FMICs with some sort of mesh since they're susceptable to high-velocity road debris.

I think it sounds like you're serious about this modification, what with the FMIC and the future engine overhaul. I still say get real aftermarket engine management in the form of a Haltech or a Vishnu TEC-II kit.
