Guest Tim78zt Posted January 25, 2004 Share Posted January 25, 2004 my friend's stock turbo just went out and he is looking for a replacement/rebuild. Any recommendations? Thanks, Guys!! Tim78zt Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 25, 2004 Share Posted January 25, 2004 I got a T3/T4 hybrid (water cooled long w/ a installation kit for water cooling) from Turbonetics - the turbine was clipped and had an S-3 compressor trim. Works well. I used my stock turbine housing. Hits lower and stronger... Small modification to make the WG actuator work and a little time to cut down t he AFM to turbo boot and clock the turbo....

Guest Tim78zt Posted January 26, 2004 Share Posted January 26, 2004 Thanks, Brad! Do you have a part # ? Tim Quote Link to comment Share on other sites More sharing options...
yo2001 Posted January 26, 2004 Share Posted January 26, 2004 If you go hybrid, would you not need a new charge pipe? 3 inch inlet at least on T4 compressor housing. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 26, 2004 Share Posted January 26, 2004 Tyurbonetics will know - tell them what you use the car for and what mods you will be making. The stock jpipe will work.. Quote Link to comment Share on other sites More sharing options...
Afshin Posted January 26, 2004 Share Posted January 26, 2004 Actually since my T3T4 (from Alex Costa) was longer than the stock unit (larger compresser housing), I had to cut 1 inch of the straight section of my stock J pipe out and put a sleeve over it to keep the cut pipe together, it was easy to do (I got a rubber connecter which has a full length metal clamp from the hardware store). Otherwise the pipe is too long to go over the throttle body. I also had to adapt the boot from the AFM to the turbo inlet, since it is significantly larger on the T3T4. I used the stock turbine housing which bolted right up to the manifold and exhaust. I love the larger compressor, no significant difference in lag, but much more flow as boost and rpm builds up Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted January 26, 2004 Share Posted January 26, 2004 If you go hybrid, would you not need a new charge pipe? 3 inch inlet at least on T4 compressor housing. that's what I always wonder. I too am thinking that my tax refund may just put a T3/04 in my future... slim chance but still a chance. But only if I can do it in a way where it basically drops and bolts in and I dont have to get stuff custom made. Quote Link to comment Share on other sites More sharing options...
yo2001 Posted January 26, 2004 Share Posted January 26, 2004 I know that you have to modify the charge pipe. I went to straight 3 inch. Quote Link to comment Share on other sites More sharing options...
Guest Tim78zt Posted January 26, 2004 Share Posted January 26, 2004 which one is the charge pipe? The one going to the J-pipe on a stock '83? Tim78zt Quote Link to comment Share on other sites More sharing options...
Len Posted January 29, 2004 Share Posted January 29, 2004 Tim They must be talking about the output pipe comming out of the turbo intake side. Which if stock would be the J pipe in our case would be the piping we ran to our I/C which in my case is 2 1/4 "and in fact I believe I had to step down connecting to my turbo intake side /outlet to 2" anyway. So may be cool with a turbo upgrade depending on what diameter is the "charged" intake /outlet? Anyone know that by chance? Quote Link to comment Share on other sites More sharing options...
Guest Tim78zt Posted January 29, 2004 Share Posted January 29, 2004 thanks, Len! I know I have nothing on my compressed side that was 3 inches!!! So I was having a hard time understanding the terminology. BTW, have you ever heard a whistling sound, kind of wavering or varying, while in boost? I must have a leak somewhere on the intake side.

yo2001 Posted January 29, 2004 Share Posted January 29, 2004 The charge pipe is where the air goes into the turbo. I guess it's also AFM boot or something similar. J pipe is 2 inch. I didn't never had problem with that with a hybrid turbo. I think the T04B compressor housing outlet is usually 2 inch anyway. (or less) Quote Link to comment Share on other sites More sharing options...
Len Posted January 29, 2004 Share Posted January 29, 2004 Thanks Yo for the clarification. Did you get that Tim; I was incorrect in my assumption... I do remember Cody mentioning awhile back about having to replace his rubber hose with a metal 3" pipe for his AFM to Turbo connection. With reference to the whisleing noise. At times I noticed something like that. It seemed to happen maybe when I get on it when car is kinda cold...I just sorta thought maybe turbo oil circulation wasen't lubed enough. Or that my turbo was slowly wearing out? Hasen't done that for awhile.. Quote Link to comment Share on other sites More sharing options...
yo2001 Posted January 29, 2004 Share Posted January 29, 2004 Yeah, the turbo howls like the bearing is going out when oil isn't warmed up. I'm sure it's not good for it. I used to try to avoid doing that. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 29, 2004 Share Posted January 29, 2004 Hi guys! Just a note on the AFM to Turbo pipe... You can remove the spring in the stock pip and cut it back some, then cut the boot itself and use it (after putting the spring back in. OK - ask me how I know... The shop that did the coonversion did this same thing, but cut the spring too far back, so that under high boost, the boot actually collapsed and split - this was after ~30K miles. The car would not idle for shxt, but ran ok above idle. I went looking for a vacuum leak and found it on the bottom of the boot next to the comprressor housing. I went and got another boot from the JY and did it the right way - no more problems. What makes this possible is that the inlet to the compressor is moved a little forward compared to stock (not much), and the bigger inlet will just match the trimmed boot. You don't have to replace the boot with another pipe and give up the other connections.... Quote Link to comment Share on other sites More sharing options...
Len Posted January 30, 2004 Share Posted January 30, 2004 Thanks Brad for additional info... What did you pay for your upgrade turbo from turbonetics. If you don't mind me asking? Quote Link to comment Share on other sites More sharing options...
