Pop N Wood Posted February 25, 2005 Share Posted February 25, 2005 This ebay ad http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=7957617697&category=33615 is selling a 350 HP LS1 out of an 04 GTO and says it has a Tremec close ratio 6 speed. How viable would this be for a Z? Do we now have a good, stock alternative to the T56 weight and gear ratio wise? Anyone know if this trans has the notchy shifter everyone complains about? The ad also says "The GTO has excellent accessory placement making it a great choice for hot rod applications" Buy it now for $6300, but only 19 hundred miles Just got the gear ratios for the GTO Tremec, BUT also says it is a T56 Tremec T56 First: 2.97 Second: 2.07 Third: 1.43 Fourth: 1.00 Fifth: 0.84 Sixth: 0.57 Reverse: 3.28 Final drive ratio: 3.46:1 EDIT Never mind. answered my own question These transmissions where first made for GM by BorgWarner before BorgWarner sold them to Tremec who now produces them for GM. And the ratios above are not very close. A little more tolarent of a lower rear gear maybe. Quote Link to comment Share on other sites More sharing options...
Dudeboy Posted February 26, 2005 Share Posted February 26, 2005 I check on Ebay ( Particularly F-parts) to see what they have on auction. I wondered about the GTO LS1 accessory placement as well. E-bay also listed this GTO LS1: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33615&item=7955919107&rd=1&ssPageName=WDVW As I am reading and researching (saving money !!!) and going with carbureted 350 and TKO 500 or 600 was the plan. However, the LS1 and particularly a LS1 from a GTO is very appealing. I will be diving in soon and I can not wait !!!! Quote Link to comment Share on other sites More sharing options...

Dudeboy Posted February 26, 2005 Share Posted February 26, 2005 SuperDan, I say go for it !!!! My wife is turning me loose with funds in two-three months, so I am anxious to get working on the swap. I had and opportunity to purchase 327 / and WCT5 and I passed on it -- and I am glad I did because I am leaning more towards the LS1 route. Again GO FOR IT !!!! Good Luck Quote Link to comment Share on other sites More sharing options...
maichor Posted February 26, 2005 Share Posted February 26, 2005 You guys dreamin' about LS1 swaps are doing the right thing. Keep watching ebay for that killer deal. Don't be afraid to look at complete cars though. It may be cheeper. And, if you are still a year or so away, the '05 LS2's are going to start showing up. LS1 prices going to get very reasonable!

Pop N Wood Posted February 26, 2005 Author Share Posted February 26, 2005 Trouble is I got looking at the Pontiac site and the 05 GTO is starting to look like a hell of a car. Only $35K, leather, LSD, independent suspension, 400 HP 25 MPG on the highway, and my truck is looking pretty ratty... Then I got thinking, the LT1 I was planing had a final hot rod configuration that looked a lot like the LS2. 400 HP, aluminum, distributorless, tunable. And that is just the starting point. No name brand parts but who cares? Gotta get a budget together... Quote Link to comment Share on other sites More sharing options...
Dudeboy Posted February 26, 2005 Share Posted February 26, 2005 Good morning or Good afternoon gentlemen, Maichor, you hit the nail on the head !!! My dad suggested I wait because sadly, a few souls will wreck there corvettes, Trans AM, Camaros and now GTO's. There are loss (hopefully not loss of life) are hot-rodders and Z owners gain.

jeromio Posted February 26, 2005 Share Posted February 26, 2005 GTO (Holden) LS1 will have the wrong pan. However, its pan is desirable for other swaps. So you could sell it, buy the F-Body pan and be dollars ahead. However, IMO, $6300 is too high. I got mine for roughly half that with only 10K more miles on it.

awd92gsx Posted February 26, 2005 Share Posted February 26, 2005 On that note... I sat in and revved up a GTO with an LS2 in it the other day. Next time I'll be sure to bring a towel. Quote Link to comment Share on other sites More sharing options...
Administrators SuperDan Posted February 28, 2005 Administrators Share Posted February 28, 2005 Good point, I am about a year out before I will be ready to do a swap anyways. Need to work on brakes and suspension first. Maybe prices will have fallen some more by the time I am ready. Quote Link to comment Share on other sites More sharing options...
Phantom Posted February 28, 2005 Share Posted February 28, 2005 Couple things. Finding an 01 or 02 F body LS1 would be great - especially if it were in a wreck that came with the T56, wiring harness, radiator fans, ECM, etc. The F body T56 has different gearing than the GTO - specifically 1st is 2.62:1 , 5th is .74:1 and 6th is .50:1. All better numbers for the lighter Z car. Mine had 3,500 miles on it when I got it in 2002. It now has nearly 19,000 miles on it. Gotta love the LS1.
