I will be looking into buying a PT-54 or equivalent and some MSD 50's.
So far, Racetronix has the best deal on 50's,($59.99 each) but Precision has the best deal on a 54 ($675).
Anywhere else I should be looking for these items?
Looks like you found the deals. I have a 54 and have had no problem with it. Might want to think about going as big on injectors as you can though. There are some new 55s on gnttype for $305 but you'll need a modded ECM. You'll also need a converter with that 54. Mine is a PTS extreme/911/whatever and the D5 was plain doggy until I switched. It now flash stalls to about 3700 and seems fine.
I would suggest a Craig equivalent....which is about a TE62, or One from Jack Cotton which will be a Turbonetics unit....Not sure who might sell them closer to home for you but Red A sells Craig's (Limit's) units and usually a bit cheaper than directly from John. He sells injectors as well.
Or call Jack and tell him the price you have received and aske what he can do.
Either way, you won't have to worry about warranty support.
50's will match up very well with that size of turbo but you do need a converter that is 3300-3400 stall.
