I have a '98 also. I'm debating Turbo or just higher compression. Turbos run really hot in AZ summers.

I've been working with Ben Benivedes who has the fastest street SE-R in the world (11.33 daily driver). He has a beast of a turbo, running 25psi. Also Louis Anaya is helping, he had a beast turbo until his car burned (not related to the turbo)

Ben is running his DE, whereas Louis went with the DET. I would stay with the DE, Ben has done some porting and polishing but are you really gonna run 25 psi? Our DE's can handle 15psi easily. Louis & Ben both agree to buy the parts yourself. You can get it all done for $1500-$1700. If you don't want the hastle I would suggest an FMax kit for $2500. I'll get a list of all the parts you'll need and the pricing.
