It's a 88 GL wagon. A little like AWD TURBO!, but I'm still gathering the stuff. Gonna' do a complete new exh. system. I've got 3" mandrel bends to build the dn. pipe, & 2.5"from there back. No cats, 2.5" glass pack. I have both turbos,(in great shape) just not sure the best choice. I'm running 380 cc injectors, boost referenced pres. reg., larger pump, heads are hogged, match ported & polished, a hood scoop feedin' a Saab 900 all alum. inter cooler, 280ZX MAF, K&N, in stock air box W/ 3X4 oval cut thru fender well. It runs really strong, but I think a bigger hair dryer could be worth the effort. Leanin' towards the TDO4 since it's a daily driver. Ideas? Thanks, S.

TD04.

Anything bigger will create to much lag.

TDO4 just fished mine & love it
