Yes & NO! The 92/93 has a smaller TB bore inlet than the 94/95 does. You can swap them, but, the pulley sizes are also different as the rotors inside turn at different rates too to make up for the smaller TB Bore inlet.

Default Pulley Size

Quote:
the pulley sizes are also different
So is the pulley smaller on the 92-93 to increase rotor speed. Also, what is the bhp for those years?

Thanks

Pulley is smaller on the 93. as far as hp i have read that the 94-95 series1 has app 25 more hp than previous years. I thought the 94'* ran same amount of boost as the 93'* just with slower rotor speed but when I done swap my boost dropped I had to put 93(2.5)pulley back on to get back to 9lbs of boost.

I did not realize there was a differance in 93 and 92'*. All I need was the 70mm tb and 95 Sc. Then the ZZp mini AFC2.0. My egr tube and everything else was direct fit.

On your mini AFC2.0 did you set it 111% all 13 settings???
Reason I ask mine ranges from 110% - 121% to WOT. I have seen where several Say theirs is set at a single giving percentage.

92 and 93 the same, the throttle bore increased to70-73mm in94/95 super charge series 1 E.G.R. TUBE needs to be adapted to larger size. I bored my92/93 E.G.R. body out to 94/95 size, that'* the way I did it.never tried using other setting, wished zoomer had better directions!!!!!!

I had a 93 3800sc and had to do nothing but bolt the 95 Throttle body and sc on. I guess the EGR tube is differant from 92 and 93. Everything was a direct bolt on with no modifications.

i did this swap last feb. plus i enhanced the airflow with a 2" overdrive pulley, a 3" intake tube, a 95 SC, 95 TB( both were ported and polished to match eachother, a hi flow cat and a flowmaster. with the enhanced airflow, i have my afc 2.0 setup in enhanced mode starting with a 126% from 1-5 and gets progressively richer from 6-13 up to a final seting at 13 of 136%. now that the temps are colder, i may go even richer at the top end of the scale because cold air is denser than warm air. as far as the egr tube to SC, i have to find another seal that fit it snuggly. it does take time to get the afc set correctly, depending on your mods, you may have different settings from others. airflow and air temp is the key.
also with overdriving a SC, since i havent seen an intercooler for a series 1 yet offered, you need to get the incoming air as cold as possible before it gets to the SC. i insulated my entire intake and built a cold air box. after doing this, my IAT temps dropped 40* you may also want to coat your manifolds too. im getting a set done by performance coatings in washington state. they do the inside and out of them. if your exhaust gas temps are 1590*, the radiant temp from you manifold is aprox 200* if they are uncoated. after the coating is applied, the radiant temp from the manifolds are 80*.
as a rule of thump, they state that for every 10* of engine bay temp that you reduce, you will gain aprox 1% HP gain.
so if you drop it 120* and you are making 300 HP at the flywheel, that is an aprox gain of 36 HP. not bad for the 190 bux they charge for the chromex finish, the satin finishes are 150 for the set .
