LS2 in my C5??
I have read thru the search area some- but I didn't really find the info I was looking for-
Fred Beans sells a complete LS2 for just under $5000. What would it take to slap that into an early C5? 97 to be exact...
I was thinking about a H&C package, different long tubes, gear change from 3:15's but then I said, well I would be close to 5 G's in mods...why not stuff an LS2 in there and start with a 400HP platform...
Any thoughts on this? I am sure at some point I would need to beef up the tranny- but what kind of dollar figure would one be looking at to just drop in a plain old LS2? Professional opinions always welcome- as well as first hand experiences in doing one...
Thanks!

I think Phil at Dynotech Engineering offers LS2 engine packages for C5's. I'm not sure what all is involved, but it is possible. Look on their website for their prices.

DTE posted a few months ago about their LS2 engine package for the C5. Sounded very nice and made very good to great power, depending on emissions and how streetable you wanted it.

and as "CARY" posted, the LS7 has not been verified to fit without major modifications and lets not mention price...also the dry oil sump situation is something I am not sure of as where to install an oil can. Plus its twice the price of an LS2! Seems you can pump an LS2 up to these HP numbers rather easily- and it looks as if it drops right in....

I have a DTE installed ls2 in my 2004 c-5 with an auto. With the 373's and 2800 stall i have right at a 22% drive train loss which left me with 425 rwhp and 400 rwtq. The car drives 95% like a stock car, the cam is very very mild. To me what is the most impressive is the TQ curve. With phil at dte doing the tuning he was able to produce 325 foot lbs of tq at only 3000 rpm. Talk about being in the power band ALL the time... there is NEVER, and i mean never a place in the rpm band where the car bogs down, it's instant GO all the time.
Going with an ls2 in such a new car was obvioulsy not the least costly route, but when I looked at what I was able to sell my ls1 motor for, and then took into consideration the quality of upgrades available for a 4 inch bore ls2 vs the ls1, for ME, it was an easy choice. I am now in a postion to have a stroked 402 with minimal cost, and finaly a 427 in I so desire.

I think the ls7 is a graet motor but i cost a little to much for what it's worth. The ls2 is pretty much a drop and swap motor. If you really go this way with the ls2 let me know and i can tell you what would need to be done.

The LS6 engine on the other hand is a direct bolt in and you can use the same wiring harness. That why I'm considering the LS6 over the LS2 engine.
Just thought I would through that out there for you. . . . hope this wasn't too late ! Good luck on your engine swap.

Fast makes a complete plug and play wiring harness for LS2 transplant in a C5 SRP in the ad was $906.00.

I don't know what other wiring changes there are if you want to swap an entire LS2 (instead of just the shortblock)... I think maybe the throttle body connector? Anyway, don't pay $900 for a LS2 harness, if you already have an LS1. Much easier (and cheaper) to adapt what you have.

I got my plug and play harness from racetronics. I have even heard that if you put the knock sensors towards the rear of the block you will not have to use the ractronices wires.
