Re: turbo 250 or 351 in my cortina?
There's a few trubo Xflow owners on this forum already. Bare in mind you will need more than just a turbo, manifold and computer. If it's not already EFi, that's a good idea. Intercooler $1000+. All the other fiddly bits and pieces like hose's etc. It all tally's up in the end.
Or, just keep an eye out for a 2nd hand already turboed 250. I found one in the auto trader for $2000, everything included, recent rebuild, just needed a bigger intercooler.
87' XF FREAK!
