I got the PT51 in today - it's roached. A good 1/16th or better shaft play. Not a very popular turbo, not even sure if it's worth paying to get it rebuilt. Oh well.

So - the TA49 is going in, and I will look for a 2800 stall converter.

So - if ya care - final config is going to be a TA49, and a stock D5. I need to pull this Pat's out and sell it, need to get the motor running first, methinks.

Make sure that TA-49 has the Garrett .63 exhaust housing...the Precision .63 is slightly larger...and won't spool up as quick.

Just checked - it is the Garret .63

I'm new here and maybe I should not comment.I have ported heads ,int manifold,worked exhaust manifs and a stock cam.My car pulls to 5400 rpm.My car many years ago went 117.5 mph (1650f egt) on a TE34 (56 mm compressor wheel) and stock cam.If you have heads and work done the stock cam is not the slug people think it is.The reason I have a stock cam is because way back when many people had lots of troubles that were cam related.Folks just put these high lift cams in iron heads and just waste energy and pound out there valve seats.

No, Please do post! All opinions are welcome.
The cam was in the car when I bought it. Other than a cursory visual inspection, I don't know if it's good or not. I guess I could mic it.

How does one see if a cam is damaged, aside from obvious visual clues?

Personally, I would never reuse a flat tappet cam.

Visual clues are good enuf...look at the bottom of the lifters.  If they are scrubbed off, the cam and lifters are bad. This will normally be reflected by the cam lobes which will look funny as well on the lobes affected.

When the lifters are new, they are slightly convex on the bottom.  If you set them on a piece of plate glass (plate glass is normally very flat), then they should rock a little rather than sitting perfectly square to the glass.

Nothing wrong with flat tappet cams.  Most failures are due to user error on break end and/or cheap chinese lifters which are not hardened.  These days lifters are being made in this country but the trick is in knowing if the set you buy is US made, or not. An used cam is generally the safest cam to install if the lifters go back on the original lobes.

It is strange that one hears about the dangers of flat tappet cams but, one seldom sees an actual case of a failure from real engine builders.


Just remember that a lifter has to go back on the lobe it came off.  You cannot shuffle used lifters around on different lobes.  Instant disaster!!!!!!!!!!!!
