MS FS: PAR 1-4 Gear set, Garrett GT3071R, Haltech F10A, Speedcircuit Stage 1 Head


New Caney TX
Time has come to part ways with my Baby and Daily driver of 17yrs. After just putting in the new turbo setup and getting ready to do some tuning, the engine started stumbling during downshifts which unfortunately turned out to be a worn thrust washer that slightly scared the crankshaft surface. I no longer work 1.5 miles down the road so a FWD racecar for a daily is no longer an option.

What’s the benefits of the stage1 head? Also do you have a reverse cowl hood I saw you mentioned that

Here are the specs from the website... but when i purchased it came with a 3 angle valve job instead of 5 and was $1299 so this is an amazing deal...
Stage 1 includes:
-Special five angle valve job
-Bowl work to blend the stock machine cuts into a larger bowl
-Sandblast clean
-Valve lash set
-Pressure test to ensure no leaks
Im keeping the hood... its definately seen better days.

Bump!! Someone needs this gearset and turbo... make me some reasonable offers... also if sold i will order you brand new 4th pinion gear. PAR has these in stock and can ship right away. After staring at the zoomed in pics I'd hate for anyone to have an issue.
