Info And Part #'s For The Ls2 This is an internal email I recieved from Nicky Fowler (Parts Dirrector at SDPC) today....
Brief update on LS2 parts and compatibility with the LS1/LS6.
I have read numerous posts on several forums concerning the new LS2 components. I have been diligently working on the part numbers, pricing, and the interchangeability. I have listed a few of the items below. Remember, pricing on new production parts is ALWAYS subject to change and many of these items have GM “temporary pricing” established from the pricing department! As we know, temporary pricing is kind of like roulette - you never know what number the ball is going to land on! So these prices are subject to change from the General on a daily basis!
I will be in Michigan all of next week and will have the opportunity to meet with GM Racing, Powertrain, HPVO, Service Parts and Performance Parts. Hopefully I can resolve some of these issues that we all have questions to and get a look into what else is coming from the General.
LS2 Parts
Intake - #89017648
Pricing - $235.75ea
At this time it appears that this part number represents the complete intake, less fuel rails, injectors, and throttle body. We hope to have some here in about 3 to 4 weeks. Just a reminder, the LS6 intake continues to shows its worthiness in independent dyno testing. When used on stock cubic inch engines with camshafts of a duration at 0.050” of 235-degrees or smaller, the LS6 continues to be a strong competitor to the FAST and much better than the Weiand and the stock LS1. In most tests, the LS6 intake is only 2 to 8 horsepower off of the FAST at peak RPM and in one test it is equal to the FAST! It all depends on the complete combination and the ultimate usage of the vehicle. Most people never talk about average horsepower and average torque and do not forget that the engine must go thru the RPM range to arrive at that peak number. A good flat torque curve will certainly add to the ability to get there! And it always improves that “seat-of-the-pants” feeling when you “mash” on the pedal!
Hard to say at this time if the LS2 will be that much better than the LS6 on a stock cubic inch engine. In pure drivability and bottom end torque, the 346ci engine may still require the LS6 intake. And the LS6 may be cheaper to install in the end! We will just have to wait and see.
Throttle Body - #12570790
Pricing - $325.00ea (could have a core charge?)
Drive by wire 90mm throttle body. Some people have posted about how to wire this to the current PCM and wiring harness. As always, expect the unexpected! Some people will think that this is all you will have to do to make this work correctly. There will be some refinement issues to the PCM regarding this change. And again, a mildly modified 346ci engine may not respond to this change. It could actually hurt bottom end torque and drivability. It will be interesting though! The LS2 intake and the 90mm throttle body should be really nice add-ons for the big cubic inch engines that are up and running.
Cylinder Heads - #12564825
Same as the 2002-04 LS6 cylinder head, no changes on the bare head. However the LS2 engine uses the stock LS1 valves rather than the lightweight Z06 valves.
Block - Part Number not available to the public at this time
We have 20-blocks on order. I should have pricing in the next 2-4 weeks. Delivery time is another issue, who knows! We could have some here by the end of the month.
Water Pump - #89017457 (Y-Body)
Pricing - $165.25ea
The 04 and 05 pumps look like they interchange with no problems. They use the same thermostat and it appears they have the same impeller internally. The castings are different; the 05 rear cover is a pressed-in cup while the 04 is a bolt-on piece with an o-ring seal. The pulleys are very different and it appears the large portion of the weight reduction comes from the change in pulley styles. The O.D. of the pulley has not changed. If someone wants to lose a quick 3.2lbs off of the front of their car, then bolt-on the new water pump. The new pump weighs 10.25lbs while the old LS1 water pump weighs 13.45lbs. There is no longer a provision to drill and tap for a temperature sender near the upper inlet on the pump. Do not forget that we have the new style thermostats in stock to fit the 2004 V8 engines and the new LS2.
160-degree thermostats #SD105160 - $24.95ea

Am also VERY interested in the fuel rail/injector part #/price, might be ordering an ls2 intake if those prices are right. the FAST is still a little too $$$$.

I will do the same for intakes and any other pieces you might be looking for. Just give me your name, phone #, & the part you are looking for. Thanks!!
do you have a part number yet?
any idea on retro fit issues with ls1 cars?
