Guess what guys???
I've got a friend who's a nissan master tech, and he just told me that they've seen a GREAT number of 240s going into the shop. The reason behind this you ask? Engine swaps~! But I was really surprised, and puzzled when he told me exactly what. He says that they are prepping the 240s for an engine from the newer V-spec SE-R Sentras~! He says that there's a kit somewhere that changes the mounting plate for the engine to accept the bellhouse transmission from the ka24de. How does that cookie crumble?

I personally havent heard too much good about the QR25. And I'm sure it costs more than getting a JDM motor.

yeah, but you get the reliability of an NA. No turbo lag, and possibly be able to legalize the turbo 240 with a system for the SE-R. I know its a lot of work, but its just news I'm sharing. Also, its good news, people out there will spend for the QR25 instead of SR20s. To me, I hope they do spend it on that kit, I'd rather have turbo~!

Exactly, Just cause your "friend" is on his third motordoes not mean this motor is junk, nissan has put plentyof dollars in the development of this new motor and itis in more than one of their vehicles---maybe its your friend's maintenance or driving that is junk.

the spec v trans is not bad at all. is used in the 02 and 03 max as well and has no prob handling the power. i have however seen a few clutch probs. i attribute this to the specs high rice appeal. it seems that quite a few people have just barely(if even) graduated from civics to sentras and they still drive like there is zero torque/bottom end.

I call them "sponge bob cars" because everyone thats young drives one, I didnt see one old person drive one. As far as turing a FF engine into a FR engine Im going to put up the 
flag too because thats a load of chit. Who would waste there time with it. And for the fact the 02 maxima transmission sucks sure it can handle power, but the throw is long and its not soild feeling (cable shifter) Also I cant heel toe with the maxima...its to far spaced between the gas and brake. Were as in my car I do it to easily sometimes, but I get use to it.

Here's a explanation taken from Trav4011 at b15sentra.net. The cars aren't crap, just had some first year problems. BTW, the 03 transmission is much improved over the 02. So the maxima transmission doesnt suck all that bad.
I found out what changes were made and when they were made... to the QR25's internal design.
Let me give you a little run down..
Nissan Japan uses the QR series motor as does Nissan America. There were a few differences between the two engines.. for some unknown reason. The American version had Federal Mogul rod and main bearings.. whereas Nissan Japan used the Nissan brand bearing. They also used an alluminum based bearing.. which is good for long term wear, but can be disasterous if you starve it for oil. (as some of you have seen with blown up motors). Also, the 2nd compression ring was an American made ring... versus a Nissan made ring in Japan. This American ring was very hard.. This is good for long term wear.. but since there isn't as much pressure exerted on the 2nd compression ring as there is on the 1st.. it took FOREVER for it to seal. This is what caused all the oil burning issues. Once the ring sealed though.... the engines ran fine. It's just that in the process of sealing, it burnt a lot of oil.. and unsuspecting customers ran their engines low on lubricant. This caused damage to the alluminum rod and main bearings instantly. Alluminum bearings also fail more catastrophically than bimetal brass based bearings. Instead of a rod knock for a few days... you got a rod thrown out of the block instantly. Piston design was different as well. The ring land height was the same.. but he composition and brand of piston was different. So.. in a nutshell.. Nissan Japan used the good stuff in their motors... and we got the crappy stuff over here.
Well, Japan realized that this was a big deal... and in mid June... decided to change over to the Japan based internals. Any engine made after mid-june... will have different rings, and different bearings. They also changed the pistons out to the Japan based parts. These engines were "phased in" if you will... and it was kept quiet. Just though that you all should know this info. Travis

well i for one am grateful for the info. and i still say the max trans does not suck. i know scc says the shifter does not feel right, but i think its pretty darn good. im not gonna compare to a bmw shifter though. all that and im not a spec v owner or anything, i just think the car gets a bad rap unjustly.
