• replace 90 jetta tdi with 86 diesel ?? by Lickman on 21 Jul, 2006 14:41
• I melted a piston in my JEtta Tdi recently. Ive been looking around for another turbo engine, but thats been hard to find. A guy at the wreckers says I can buy his 1986 Jetta non-turbo diesel as a replacement for my broken 1991 and fit it with my working turbo head. Is this even possible?
  
  Cheers,

• If it is the stock engine it is actually an IDI, not TDI. The 86 head might fit, it depends if it has hydro or mechanical lifters. I'm thinking it would be mechanical and your 91 would be hydro.

• I second the its not a tdi, but a td idi.. tdi 1.9 direct injection first appeared in us in 1996 in the passat... I beleive the hydro heads started in 1985..
