LS/CRVTEC 411!!!!
I found this ad on purehonda.com and I just had to let everyone know what this guys had to say about LS/CRVTECs and how much of a bad idea it is......Can anyone prove him wrong?...Anyone here have good experiences or have or know someone running one strong?....Voice all your opinions on LS/CRVTEC setups and places that know how to build them right!!....I want to go CRVTEC but what do ya'll think....Go for it?....or 4get about it?...

No problems from those that I know. You want one done right on the East Coast, call Jamie at J Speed. He can answer most, if not all, of your questions about the conversion, reliability and so forth. 704 982 DRAG.

Re: LS/CRVTEC 411!!!! (Rizz)
First of all - let me point this out
"The intention here is not to discourage someone from building an LS/VTEC. Rather, it is intended to give someone considering one of these hybrids some things to keep in mind before diving into the costly process of building an engine. "
Read that a few times and understand it then go re-read the article. I have a fully build CRVTEC and I could care less about R/S because all in all it is not to far off from a GSR and hell I really don't plan on running this motor for more than 50-100k miles. Secondly, most of his opinions are right but just conservative, very conservative. It seems as though he's upset about the idea of ls/vtec. I will give him one thing however, ls/vtec done right is anything but cheap and is not a cheaper alternative to a original vtec motor. Build it right - yeah, you'll make some great power. Build it wrong and you'll be picking up pieces off the side of the road.

Re: LS/CRVTEC 411!!!! (stizzit)
Well I do agree with him actually...when it comes to stock internals.
Although the LS/CRV R/S ratio is close to the GSR/ITR..it is worse and the internals are weaker. Combine the two and you have a much weaker engine (internally)
Now, if built correctly (as he said) you can rev it higher obviously.
I think his 7800 "built" revlimit is a bit on the low side...but again it depends on how its built.
Using aftermarket pistons, which are lighter helps reduce the load on the cylinder walls. Aftermarket rods are stronger so they can handle the added stress.
And finally a crank girdle must be used for "ultimate" reliability. Like Ive said before, Honda uses a crank girdle on the GST and Type R from the factory. Im sure they wouldnt spend the extra money if it was 100% necessary. (The B16A does not use one due to its good R/S ratio).
I personally believe that on a stock block, around 7500 RPMs should be max..and that is depending on gear also. The higher the gear, the more load (stress).
So maybe take 1st to 7700, 2nd to 7600, 3rd to 7500, 4th to 7200...you get the idea.
With a fully built (pistons,rods,girdle) I dont think there is a problem with 8500 RPMs.
So in conclusion...build it right...or dont rev high.
