Dont know about cost effective..but I happen to like pre 1998 Z's...the front end is just sharper IMO.

They're totally different. You need the LS1 accessories.

The Tranny swap for t56 is what kills it for me.

I thought about it but then I swap an lq and t56 for about $2500-3500 or more and have stock power.

Or I could spend that much and have a built 355 w/ heads/cam. For someone who's not so hardcore into it, it's not worth it.

You can check out my swap in the link in my sig. I had a H/C LT1 that ran 12.14 and when I swapped in the LS1 I put a TR224 cam, PS LT's and run 12.15 but gained 8 mpg!

Or did you just replace it with a lsx harness?

What else is needed for a lsx swap I.E- engine parts, electrical?

I will add as needed
Rob,what? Lsx?! Come on man. By the time you're done and have it running, you will have spent more $$$ than just doing an all out, ***** to the wall, LT1 383/396 But good luck bro.

Suxs but not a deal breaker...thanks for sharing.
Still a tuff decision Nitro LT1 vs. Lq9 block LS.

For me the MPG w/ a close to stock cam is what will likely be a deciding factor. I know the LS def makes more hp but is it def. better at gas mpg'z while doing so?

I've been leaning on LT1 for some time now becuz it seemed the better mpg performer and becuz I have it already. But I hadn't truly confirm'd mpg.

I actually want stock power but best mpg'z. But I have to forge out the entire bottom end before the swap so my costs go up. (N20)

But I read on a different thread. If you have a T56 already...you don't neccesarily need to swap it. You should be able to swap out the input shaft and front cover. Thereby converting your older T56 to match to the LS engines. So cost goes down...but I'd want to refresh my old 1 it needs it.

The only questions would be how much better internal design is in the later T56's? And can we keep our clutch forks rather than go with the later hydraulic clutch throwout? and if not...how bad is the later version clutch throwout problems?

I get 23 mpg with a 3600 stall and 3.42 gears so I think that is pretty good. My LT1 stock M6 didn't get that. As far as converting your T56 you are better to sell the whole setup to someone that is converting. You need the LS1 bellhousing, flywheel, clutch, and slave anyways. Keep in mind if you do the LQ motor you need the car intake, injectors, LS1 car harness and pcm, car accessories, car engine mounts, car oilpan/pickup tube. It will nickel and dime you to death.

There's just no winning. lol.....hence the debate to forge and N20 old faithful or not!

IMO unless you have alot of money into a roller, you might as well buy an LS car and save yourself the hassle. I've seen them below $5k which when calculating time and cost required for the swap it isn't much more.

not necessarily, prices aren't as bad as they used to be. I've seen quite a few nice WS6 and SSs for around 7-8k

how much u think forged bottom end rotating assembly for lq9 block will end up costing?
not sure but if I went this route.....the nickel and dime route would likely be the way.
becuz inheriting a whole other car with its own problems doesn't mean I wont have to work. plus I can nickel and dime it slowly....like start the motor and take my time....gather all parts and then when its all ready round up the last pieces for the T56.

Anyone know if later T56's are SOOOOO much better than olders?
