Turbo recommendations?

[SuperSix]

Since it looks like I won't be getting my turbo from Bryan - I need some turbo recommendation s. The MIA turbo is/was a PT51, that's what was on the car at one point.

I don't have a downpipe either - if that info helps.

I don't plan to competitively race this. Streetability is more important.

Car has:
Motoron 60's
202/202 cam
Pat's 10" 3500 stall converter
Stock IC

Thanks in advance.

stock heads and stock ic work well with a 49, or a 44.  Easy elevens on alky...but, the converter is way too loose for those turbos.

That converter, if it actually stalls in that vicinity, is for something more akin to a 63 or 66 turbo which, in turn, is wasted on stock heads and ic.

For a street car, I would look for something in the 2600-2800 range, or even a stock converter....i t will be a lot more fun to drive and get better mileage to boot.

it is not the elevation per se...it is what a given turbo requires to spool up

A stock converter will be a hair tight, but, if you add a little timing in first/second and lean it down a bit, it will work.  It will be fine from a roll.

Can one get a D5 restalled? Isn't the D5 2800?

[SuperSix]

2200 apparently

Maybe send the 10" back to pats and get it restalled?

7000 ft is a totally different game, I agree.  No air is no air.

That turbo was always sluggish from what I recall...and prone to blowing up as well.

The stock converter was a D5 and generally was around 2200.    D5 is usually meaningless these days as many were restalled.  The GM replacement for it usually stalled around 1800-2000.    The restalled 2600-2800's can be from any 12" core so you cannot really make any assumptions from what is stamped on the unit by the factory 25 years ago.

Tell me about it (T63e).

You can do the 63ish turbo on stock heads, however you will end up with diminishing returns as the heads do become quite the limiting factor.

The good news is that I am at 27psi with 25* of timing now that the alky is spraying over the straight 91 and propane.

Alky *and* propane? Hardcore.

and, if you have the stock IC, then you are pushing about 33 psi at the turbo which is on the downside of its efficiency.... .

also, if you have a stock cam, it has been dead for about 400 rpm when it reaches 5200 and you have a turbo that will fill the cylinders easily at 6000 rpm.  So you have given up about 800-1000 rpm on the low end due to the slushy converter and cannot use the capability of the turbo on the top end....

Combination, combination, combination

Well Damn. Nice.

There's a TE60 local, but I assume that's way too much for my car.

Do you have the inlet bell too?

Make me a deal, mang!

definitely over kill ...but I have a slightly used turbonetics T-72 ball bearing p trim that I will let go at a reasonable price.
