Well considering I have a red I think I am about on par with that. WHe nI get back I am gonna have my car thrown on the Dynojet near where I live to get a more apples to apples comparison.

You would be lucky if your bearings last more than 40-50k on any built motor! Most people are lucky to get 20-30k. However lower timing, lower boost, and lower torque will help your bearing last longer. If you want it to last 100k miles you should have kept the stock motor w/stock turbo. sorry...

I was refering to how long the actually cylinder walls would last. But you kinda helped prove the point that the LR2.4 will lost as long as the 2.3 when it comes to bearings.

Given the same rpm limit yes. Compared to a 2.2, 2.1 or 2.0 i agree, physics says the shorter stroke motors will last longer.

All built motors, regardless 2.0-2.4L will eat bearings relativily the same as long as the cylinder pressure and torque are the same.

Correct, however I have seen some built GSRs that have a worse r/s ratio that the LR2.4 last for ****ing ever. The LR2.4 is a newer motor however the longivity should not be questioned.

The only thing that a 2.0 will out last a 2.4 would be the cylinder wall... I don't see that being a problem anytime soon. Also as long as you build your motor with lightweight/strong parts it will last.

I know but you made the statement that the 2.4 would probably last longer then the 2.3 which is why I assumed you were talking about cylinder wall wear. Which ultimatly is a moot point as the bearings will go around the same time so longevity really should have no bearing on motor choice.

This coming from a person that revs a LR 2.4 to 8700 rpm.

Show off !!!
Thats a real nice power band.

I dont see any built motor that is used for what its intended ever lasting 100k miles. Something will always invariably kill it before that (FPR failure or blown off line, headgasket failure, bad fuel, etc.). My rule of thumb from domestics has always been 40k. If I can get 40k I feel I get my moneys worth and anything more than that is a bonus. My car goes back and forth from being in vacuum to the next time I take it out its 30-32psi all the time. I have 8,000 miles on it so far and its been pretty even on abuse/babying.

Mike, recently I purchased a 4g64 crank from you guys about a week or so ago. I tried calling a few times this week, left a voicemail but never heard back. I no longer need the 4g64 crank since I am doing a 2.1 now. I'll try calling the shop again tomorrow. Thanks

So I've decided im going with the 2.1. Were doing the build right now with Maperformance Howard Rods, Wiseco 9.7:1 1400 HD pistons and of course all of the other parts needed. Hit up Nate or any of the dudes from Maperformance if you need any parts. They hooked me up with awesome prices that I couldn't turn down

Also, I've been hearing alot of people talk about the 2.4 block having HG sealing issues. I ordered the Fel-Pro multi-layer Gasket. Think I will have any problems?

I haven't heard any thing about the Fel-Pro multi-layer gasket, where did u get it ?
BTW I got the AMS head gasket.

I got it from maperormance. They recommended it too me, they said they've never had any problems from it but I thought I might as well go ahead and ask.

dont know about the HG sealing issues but i have not heard or seen any with the 2.4.
