The Power Enrichment Vacuum Regulator (PEVR) is an important component for the pre computer '78'-'80 draw through turbo cars. They aren't reproduced and so far nobody has come up with a good alternative. I had one in pretty bad shape and recently had it rebuilt by a company called TTA...

Can anyone ID these headers? I think they are they are a new old stock set of Hooker headers for the 84-85 hot airs.

Great video about Buddy Ingersoll's career and his involvement with the Buick Motorsports program.

Does anyone happen to know the approximate weight of a 2 dot rod?

I think everyone agrees the compressor housing on the '78 to '83 carbed turbo is a terrible design. The 3 bolt flange, commonly referred to as the "foot", that mounts the turbo to the intake manifold, seems to get a lot of the blame for lack of performance. The truth is the entire housing is too...

One of my all time favorite Buick V6 engine builds covered by a magazine, this appeared in the May 1981 issue of Hot Rod magazine. It was written by C.J. Baker who wrote several articles about Buick V6 performance from Smokey Yunick, Ray Baker of Baker Engineering and Jim Bell of Kenne Bell.

Looking for new high compression pistons for an NA application for use in production 4.1 engine or 3.8 with stock length rods and crank. The higher the compression the better. Will consider sizes from stock bore to .060 over.

These are some of the distributors I have collected. I thought it would be interesting to compare them side by side. There is a very big difference in size. The HEI is a great all in one distributor, but it is huge. MSD made distributors in both cast aluminum and billet aluminum bodies. I don't...

I had a wanted ad for an 84-85 turbine housing. I purchased a good turbo core from a member and closed the ad. Today I received a PM from a brand new member named Johnsonbe44 telling me to contact someone at a Gmail account for one and what a great guy he is to deal with. This is undoubtedly a...

Looking for a good, internally UNDAMAGED 84-85 turbine housing. Need one that also has good threads on the studs. Would consider a good core turbo if no internal contact damage to either the turbine or compressor housing.

I always thought this was an interesting car from "back in the day". This Buick Regal was given to Dick Baker by Buick in an "unofficial" sponsorship deal since Buick Motor Division wasn't allowed to "officially" sponsor NHRA Super Stock. I don't remember all the engine particulars, but it was a...

Here is the picture that disappeared from post #4 above.

Anyone have one of the 1978 turbo 2 barrel carb plenums laying around? I have been looking for a while and can't seem to find one.

I need 1 used standard bore 86' turbo piston GM part #25526298. The part number is located inside the skirt. Must be nice condition!

Does anyone have a picture or part number for the left (driver side) exhaust manifold for the 1978 turbo engine? I know what the 1979 looks like but I can't find any pictures or part numbers for the 1978. I have a 1978 left side manifold but is it the correct one?

Thought I'd show the difference between G body and H body headers without stepping on ek02's header build thread.. These are Hooker Super Comp headers for a Regal or other G Body with 79-87 high port heads. Notice they sweep straight down from the cylinder head and the square ports...

Looking for 1978 or 1979 Lesabre Sport Coupe Turbo project car. Running or not. Not looking for a high dollar perfect car, but also not looking for a rust bucket.

Anyone ever seen one of these? I found this in a stash of parts owned by a long ago retired Buick engineer named Byron Scott. Byron owned the 1986 GN that was sent to ASC and used as a GNX prototype. I had no idea what it was at the time I bought it, but it looked cool and I had to have it. I...

This instrument cluster was supposedly removed from a GNX prototype car by a Buick engineer (not associated with the GNX project) who wanted one as a keepsake. I was hoping someone here would know if it is the real deal or a copy.

I have a couple sets of NA headers with flanges designed for low port heads. It looks to me like they would work fine on high port heads (but not vice versa). Anyone using a low port header on high port heads or know of reason not to? The header port at the flange is larger than the...
