KB and a '98 GT Questions

[tjm73]

I'm giving serious consideration to selling my 90 GT to buy a KB for my '98 GT now that they have released their 96-98 kit.

In addition to the blower kit, what does a KB need to be optimized? The engine is not coming out of the car if I do it. The car is 100% stock except for the Magna Flow cat-back.

On the short list...
Throttlebody (what size?)
MAF (again....what size?)
Cold Air Inlet Tube
Custom Computer Tune by a local KB sales and tuning specialist (Kennedy's DynoTune, Buffalo NY)

Depends on what your plans are in the long run. If it is a daily driver and only sees the track once in awhile. Then the kit comes w/ everything you need. The 9psi kit will bring your car to its limits safely. If you go any bigger w/ anything you will have to start upgrading your MAF and bottom end. w/ the 9psi kit you should be around (at least for 99 & up) arond 400 rwhp. I am not sure the power difference w/ the earlier years. Good luck man.

To optimize the blower, intake and exhaust mods will be necessary. Quite honestly, if you can afford it, I'd consider having the stock NPI heads ported. That, along with a set of stock PI cams found cheaply on EBay will put you ahead of the '99-up crowd without altering your compression.

Aside from that, A full exhaust, larger MAF and 75mm T/B will net you the best gains with the kit.

To tell you the truth though, I'd be saving up to beef-up the bottom-end myself. It doesn't take a lot of boost to crack a ring landing. Running the 400hp level for any length of time is going to have detrimental effects sooner or later. It's not a matter of if a rod or piston is going to go south, but when. You can beef up your engine for as little as $1,199.00. Pretty cheap insurance against almost guaranteed failure later on, if you ask me.
