I did a short ram on my Celi (3sfe) recently. MAF adapter and cone filter, nothing fancy. Noticed some small hp, torque gains in the higher RPMs, but nothing huge.

I've read turboing a 3sfe=blown engine. Everyone suggests an 3sgte engine/ecu swap, but I hear the wiring is a pita. If you're intersted in that, there's tons of info on this site and others to sift through.

I've seen one 3s-fe that was turboed and ran correctly. Unfortunately, to not blow the motor you don't get a ton of power out of it and it's expensive. A engine swap is definitely the way to go if you are looking for a serious improvement and best bang for buck. On the plus side you're ST is the lightest of the celica family.

Wiring gets more complicated the newer a version of 3sgte you use. I've heard that a second gen version of the motor is the best balance between wiring issues and performance gain.

Turbo 3sfe has been done, but it's a lotta work.

CAI is eaiser. I too have what Futant3 has (replaced entire airbox with cone filter & MAF adaptor).

A full CAI will require a move of the battery to the trunk/cargo area, and routing of the piping thru the fender. There's a big hole there that makes it perfect (where the stock airbox & resonater sits).

I can't find the site that had detailed instructions on it now :( But it can be done with about 15 bux in parts from Home Depot, plus the cone filter (about 20 bux).

Same here, MAF adapter and a Cone Filter.

So back to turboing the FE in the 4th gen... About how many pounds of boost can be safely had? is 150hp a realistic number without internal mods? Also, does anyone know the weight of an ST? I have an '87 and it feels like a featherweight compared to my 240sx. I also have suspension wear, but thats not the point.
