Power Upgrades for an Intercooled 1st Gen
Apologies for posting to multiple forums, but as they say "knowledge is power" and power is why we're all here.
I have a 91.5 intercooled CTD automatic in a 93 chevy 1500. Current mods: MasterPower turbo (don't know the sizes), BHAF, open 4" exhaust (straight back),
and ground fuel pin, starwheel turned down all the way. Lots of smoke once I hit the go pedal. Some go, but not much - EGTs goin' up real fast tho.
Only get about 8psi of boost. Lot's of white smoke at idle.
Anyway, recently resurrected the project after a 3 year hiatus (translated: divorce and custody battle) and want to give her (the truck) some Christmas presents.
This is what I'm thinking:
KDP kit
3200 Spring
Fuel Pin (Denny T is looking really good right now) - any suggestions
Water/Methanol Injection (Snow Performance???)
Propane Injection - suggestions/advice???
Replumb the air intake and intercooler pipes (it's a mess right now)
Any comments or suggestions?

Kdp kit: can't hurt
3200 spring: Absolutly, best 20 bucks you'll spend on your truck.
Fuel pin: Check out M&H Inc. They have a selction of profiles so you can choose which best fits your needs, they are a sponsor on this site, and they are awesome to deal with.
The rest I'm not qualified to answer...but some one will... I promise.

lots of fuel and no boost... you mentioned your intercooler plumbing was in disrepair. it sounds like you have a pretty hefty boost leak. the white haze at idle... well thats the old girls cold blooded traits showing thru. if you'd like to clean some of that up the 1/8" timing bump helps tremendously. i'd stud the head before messing aroun dwith too many power adders. water/meth you should be ok with, propane however i'm not really sure... i'm not up to par on my diesel drugs.

after you get your boost problem solved look into a nice set of injectors... possibly the best upgrade other than a turbo

i would definately remove the lock of the fuel screw and custom cut your pin get a 4000k GS and remove your injection head and get it machined to a 14mm plungers and i believe you can do a small amount of tweaking to your diaphragm and get some oversized fuel lines and 6x9 injectors from New Era and youll be set bro and a good S300 turbo

Thanks guys. I've looked at the M&H and Denny T pins. I think I'm gonna go with the Denny T and the 366 spring. I've got a MasterPower turbo on it now and it barely gets 8 psi. Don't know the exact config. The shop that did the original swap 6 years ago put it in cuz the stock was doing diddly. This one doesn't do much either. There may be a boost leak somewhere, but it also may be a lag ***** as well. Can't tell at this point. I know I'm getting plenty of fuel cuz it's coming out the *** end. It's at the body shop right now getting a massive make over. I'll post some pics of the turbo and the 'quality craftsmanship' in a couple of days.
