Has anyone found a company that produces cams compatible with the factory vvt? I know comp recently released one for the new vvt vette so hopefully were not too far behind.

 

your only hope is the cams out of the 2.4 le5... not much of a gain and would require a tune.

 

Damn vvt. Its not even worth the 5 hp gain over the previous 2.2 when you look at how much it hinders the ability to make more power.... hell i may as well swap on a cavy head throw stage 2 comp cams in and lock out the vvt.

 

amen to those stage 2 comp cams

 

or boost it and call it good

 

the l61 head wont work due to the oil passages in the block i believe the lap/le5/lnf all share the same block. buy a le5 and throw in there. and swap your ecm. if your willing to swap to a l61 you might as well pick up an lsj (just as much work and a lot more power)

 

or after looking in my intake ports and fuel injector holes upgrade the valves (they look like toothpicks) and port the head there is plenty to gain from that.

 

Its getting boosted, just waiting for my damn intercooler to show up.

 

bump

 

kinda bringing back a dead thread here.... but has anyone swapped heads or deleted their vvt on the LAP motors?

 

Not sure.. but I was told that the LE5 Cams should work with the LAP Head.

Ask ZZP they will know for sure.

 

zzp said le5 cams dont work, swapping heads with l61 or lsj a possibility?

 

LE5 and LAP head are the same bare P/N which means the casting is the same. they should swap physically.

However. i do not know if the deck heights are different which wont allow the ZZP cams to work. the valves may be too close to the top of the piston

 

LAP has a shorter stroke

 

^ right. i had posted in teh other thread about that. shorter stroke, same bore adn head P/N seems to me that there should be no issue, assuming that with the shorter stroke, and less compression that the piston doesnt come up any higher than the 2.4's

 

i seen it over there. thats as far as the valve clearance issue, i dont have the numbers for the LAP duration but im sure its shorter as for a 2.4 would almost have to be open longer for the .2 liter difference. the cams themselves are diffrent part numbers, it may also be that the refrence for the position sensor is diffrent allowing for mistiming or over/under compensation when tuning

 

Has anyone tried the le5 zzp cams on lap motor? I want to get cams but nothing for the lap.. But the head is the same so should work?

 

One guy did but we think he screwed up timing and bent his valves and such.

The head is the same but duration is different

 

yea after 1 guy bent all his valves no one else tried. i mean, if you want just make sure to go ahead and turn motor over by hand before starting it

 

My brother told me is the same head they should fit and a shorter stroke wouldn't affect it. Buy since he knows more on v8s i wanted to ask here haha. I told him about the guy that bent all his valves and told me they did not get the timing right and it shouldnt happen. Anyone got the specs of both engines to see what the differences are? I might give it a go if my brother approves lol.

 

i had looked for specs for quite a while when this thread had started. i couldnt find much of anything. maybe you could have better luck now.

 

I found some but i took screenshots lol ill post them soon. Thanks

 

Lol this still hasn't changed?

 

Changed in what way? Im saving money for coilovers but might buy cams and everything needed to experiment but idk if i should lol

 

Do it.
