Scottie-GNZ Posted March 12, 2001 Share Posted March 12, 2001 Anyone looking to do a twin-turbo SBC (Myron?) might want to check this out. This is a little pricey but absolutely the best way to go as you will never have to worry about cracking or leaking headers. The high cost can be made up by the fact that you would not need large or expensive turbos. A pair of stock GN turbos would do just fine and there are experiments going on now that have TT GNs with 2 stock turbos making over 800hp. I believe the total cost here would be less than a S-charger setup. http://www.turbobuick.com/bb/Forum7/HTML/005489.html ------------------ Scottie 71 240GN-Z Scottie's GNZ [This message has been edited by Scottie-GNZ (edited March 12, 2001).] Quote Link to comment Share on other sites More sharing options...
Guest pauli Posted March 12, 2001 Share Posted March 12, 2001 cool... doesn't look like the most efficient design in the world, but i guess the price makes up for that Quote Link to comment Share on other sites More sharing options...
Andrew Bayley Posted March 12, 2001 Share Posted March 12, 2001 HEY!!! Those are MY old manifolds!!! Seriously though, I had a set of manifolds that looked nearly identical to those. I originally bought the kit for my Z, but I couldn't fit the turbos The strut towers were in the way and the turbo's sat too high. I would have needed to do A LOT of sheet metal work to get it done. I will say though, the idea is still very tempting . I tried to adapt my kit to my Impala SS, but the time and money was more than what I wanted to invest into my daily driver. Oh well... Scottie, where do you keep finding all these "gem" pictures? -Andy Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted March 12, 2001 Author Share Posted March 12, 2001 Most of my pics come from the turbo Buick forums. Those folks are insane when it comes to HP. One of our own Z-car owners, Greg Kring, also has 2 GNs. One is a 3700# street-driven stageII and he recently sent out an update. He drove the car to the track and it clicked off a 10.45 @ 131+ on ET Streets AND PUMP GAS. Says the car picked up both front wheels despite spinning the tires. With race gas it has a best of 10.06 @ 137 with only 19# boost . Thats 764 RWHP by my calculation and with slicks and 25+# boost, I will need another calculator . RickB, did you see him run? BTW, any news on your engine knock. Before you dive into the engine, make sure the distributor advance is not malfunctioning and causing severe knock. If you continue to run NOS and do not already have it, I would consider a knock sensor and some device that can retard timing or shut down the NOS if it detects knock. ------------------ Scottie 71 240GN-Z Scottie's GNZ Quote Link to comment Share on other sites More sharing options...
Sean 83ZXT Posted March 12, 2001 Share Posted March 12, 2001 Hey Scottie what ever happened to good old Greg's Turbo Z? His page is never updated and I don't see many posts from him on zcar.com. That Z was a work of art! ------------------ Future 12 sec L28ET Driver Quote Link to comment Share on other sites More sharing options...
MYRON Posted March 12, 2001 Share Posted March 12, 2001 He Scottie, thanks for the heads up on the manifolds. I probably wont pick them up right now because I am still somewhat up in the air on my total package for the car. I wanted a unit with a 5 or 6 speed but the chassis is for an automatic and I have all the computer/wiring to make a 4l60E work. Eventhough it is an automatic they are really nice trannys's I love the one in my TransAm. It shifts hard and has been bulletproof with my abusive driving for 120,000 miles.

Scottie-GNZ Posted March 12, 2001 Author Share Posted March 12, 2001 Sean, Greg's turboZ IS a work of art. Last time Myron and I were at his place, it was under covers and the engine was in some corner in his garage. Bet nothing has moved since. If I had a daily driver that had mid-9 sec potential, I would probably be pre-occupied also. Greg has tired of the zcar.com scene and combined with his busy schedule, does not get online much anymore. I am going to try and convince him to drop in on this forum every once in a while. ------------------ Scottie 71 240GN-Z Scottie's GNZ Quote Link to comment Share on other sites More sharing options...

I have no idea how that could happen - I tired of that place years ago. BTW, for an example of a kick-a$$ Twin Turbo SBC, check this out: 1982 1200HP/1000TQ Twin Turbo SBC 427 Corvette Freaking incredible! Not for those without DEEP pockets.

DavyZ Posted July 16, 2002 Share Posted July 16, 2002 CRAP! I can't get into Scottie's link! For some reason, I'm "not allowed." That really bites. I'm trying to build a turbo SBC, and a twin is not out of range for me at the moment. Grrr... Any suggestions? Take MS Exploder and shoot it?

Pop N Wood Posted July 16, 2002 Share Posted July 16, 2002 I couldn't open Scotties link either. Did you notice on Pete's link, the first TTSBC dyno curve never hit a torque peak. Torque just keep climbing right up to the 6000 RPM redline. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted July 16, 2002 Author Share Posted July 16, 2002 The Buick forum had a recent database crash and those files were lost. Sorry. Maybe someone here captured the link to the guys website and could post it. Quote Link to comment Share on other sites More sharing options...
pparaska Posted July 16, 2002 Share Posted July 16, 2002 Yes, Jim, I noticed that too. It would seem taking your foot off the accelerator would be hard to do! Quote Link to comment Share on other sites More sharing options...
