Hello all . I have a 98 Vette 6speed I have a chance to buy an LS2 out of a 05 Vette with 6speed I'm pretty sure it will fit in mine but thought I'd ask for some input on this swap .
Thanks

 

You will need knock sensor extentions and thats about it. If i was you i would put a Z06 intake on it and scrap the ls2 intake..

 

What is the difference between the Ls2 & Z06 intake ?

 

If you want to sell one of those 6 speeds please let me know.

 

Depends on how complete the motor is. Read through my install here.

 

And lose the 90mm throttle body??? Port it and keep it or get a FAST.

 

isn't the ECM puter differnt too?

 

There was a recent thread where a member flow tested LS1, LS6, and LS2 intakes and the LS6 flowed the best throughout the RPM range.

 

Just did this swap.
1- Have to buy a knock sensors adapter harness use the LS1 sensors
2- Have to buy a cam postioning sensor harness
3- Have to grind the right side motor mount slightly to fit on to the block.

That is it.
No need for a PCM change. PCM doesn't care. You will need to get it tuned. I built a LS2 402 stroker and put it in a 02 zo6 and used the same tune until I had time to dyno.
This is an easy swap if you know the issues up front. I had to learn one step at a time. Once it was done, I loked back and said "Gee this was easy if some one would have told me these issues.
I can tell you where to buy the harnesses and where to grind on the motor mount if you like.

 

here's a little blurb I found on Popular Hotrodding

FAMILIAR FOUNDATION

Like we said, GM says the LS2 is built on the new Gen IV small-block architecture. The primary difference between it and the previous Gen III engines is a new block casting. It actually is just a revised version of the Gen III's cylinder case. In fact, the blocks are so similar that many of the Gen III parts carry over, including LS6-style cylinder heads used on the LS2. Here are the differences between the Gen III and Gen IV blocks: Aluminum and iron (truck) versions are cast with new oil galleries to facilitate Displacement on Demand technology (see sidebar story).

Engine knock sensors relocated from cylinder bank valley to external locations. Camshaft position sensor relocated from the rear of the block to the front. Cylinder bores increased from 3.90 inches to 4.00 inches (LS2 applications). Similar to the LS6 block, the PCV valve was moved from the rocker covers to inside the valley.

The remainder of the block's features, from the six-bolt main bearing cap design (four vertical bolts and two cross-bolts) and deep-skirted case remain unchanged.

At the bottom of the block, LS2 engines installed in Corvettes receive a revised oil pan. Redesigned interior baffles in the pan are designed to ensure an adequate oil supply to the oil pump pick-up during high-load cornering maneuvers. The previous Corvette/LS1 combination used a "gull wing" oil pan design, but oil starvation was an issue that more than one enthusiast encountered on the racetrack. With the new, wingless oil pan design, the Corvette's oil capacity is reduced from 6.5 quarts to 5.5 quarts (with a dry filter).

 

Quite a few of us C5 drivers have LS2s installed. I bought mine from one of our sponsors SCPC (Great guys that stand behind the product). I needed to get a knock sensor harness and cam sensor harness. I went with the LS2 throttle body and FAST intake.

 

I know the oil pans are different can I use the LS2 oil pan on the C5 ?
Thanks

 

yes i too would like to know if the ls2 pan will work with the c5

 

Either C5 or C6 oil pan will work. I think there are advantages to the C6-so does GM.
