rocks Posted June 28, 2009 Share Posted June 28, 2009 I have had this 1981 for about two months. I think over that 2 months I have read so much on this site my head hurts. I had a t04b that I had got for free, along with a t4 flange. I had too dig them out as I couldn't remember where they were at. I stick welded the manifold with a 6010 rod inside and out. I also pre heated it with a torch. Next is the wastegate pipe when I can find a place out here that sells some schedule 40 pipe. This turbo should be good for about 300-350 whp without blowing a bunch of hot air. I hope. Quote Link to comment Share on other sites More sharing options...
letitsnow Posted July 1, 2009 Share Posted July 1, 2009 Very nice stick welds! What size is the hot side on that turbo? My t04b had a huge 1.32 ar housing, it's pretty cheap to get the right size t4 housing if it's too big. mcmaster.com has all sorts of stuff if you don't mind ordering.

rocks Posted July 1, 2009 Author Share Posted July 1, 2009 .60 compressor housing and a .81 exhaust housing. I had measured the wheels a long time ago probably over two years ago. If I remember its either an S or H trim. I can't really order anything right now which sucks. Decided to go back to school for welding due to the oilfield dropping out. I am trying to do it out of as many free parts as possible. I have a top mount intercooler out of a subaru I am going to use as a front mount. Its aftermarket so its pretty damn big.

Careless Posted July 1, 2009 Share Posted July 1, 2009 very nicely done to keep the stock setup. it's often hard to weld cast manifolds so nicely, especially with a stick! should be loads of fun! Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted July 2, 2009 Share Posted July 2, 2009 If it's the S trim, ypu'll be a bit better than the stock turbo. I have a T3/T4 S-3 trim on my ZXT. That .81 exhaust housing will kill your low end, and the S trim compressor housing will limit your top end. Quote Link to comment Share on other sites More sharing options...
rocks Posted July 2, 2009 Author Share Posted July 2, 2009 I will give it a shot. If it doesn't work out hopefully by that time I will be able to afford another turbo heh. The turbo came off of a kit from a v8, made in the 80s. I don't think it has been ran. Quote Link to comment Share on other sites More sharing options...
turbojohnny Posted July 2, 2009 Share Posted July 2, 2009 wow, i have never seen stick welds done so nicely! Quote Link to comment Share on other sites More sharing options...
rocks Posted August 3, 2009 Author Share Posted August 3, 2009 I have found out the specs on the turbo. I had to put an old hard drive in my computer and found a file from where I had measured the wheels. It has a V-trim compressor with a P trim turbine. From what I have found its possible to make around 400whp on a 4 banger with about 25 psi. So around 15 on pump with a 2.8l should hopefully be fun . If it is not enough power it is possible to put a 60-1 wheel in it for around 200-300$.
