catera motor swap ls1?
I'm sure this has been discussed a million times, but I know it has been done by lpe and in australlia they have the same chassis with an ls1 in it. My question is has anybody done it on their own? Does anybody have pics of the install? I kind of want to know what I'm getting myself into. I have very good fabrication tools and skills, so, I think if I had to I could make everything myself, but I'm wondering if the GTO k-member would bolt in as they are built off the same chassis. Any feedback would be great. Thanks.

Id reccomend contacting HSV about how they get the 5.7 fitted to the automobile. As for transmission wise, I do know that they use a Tremec T-56 for the manual option and then a specially geared 4L65E for an automatic. It would be easier to get the manual transmission because those can be found in the US whereas the 4L65E is specially geared by HSV so its probably not available here (unless you wanted to order it - $$$) Also, you would want to find out if they are using special/better rear end gears.
For now thats all I know about this situation. Im not sure what they do differently or if they do anything different at all to get that engine in.
Here are some links too:
There was someone here by the name of LS1 Catera Project that thought about putting the LS1 in the Catera, or if not that... the Northstar maybe. As far as ive seen, or heard, he hasnt done anything engine wise to it except to what it has now; the 3.0 V6.

Re: catera motor swap ls1?
Oh, and you could ask them that question too.. retaining to the GTO's crossmember. Techinically it should be the same as the Commedore's and may just fit in unless theres been safety regulations that have changed its design. Reguardless you should contact HSV.
