I know that since I'm running 14psi that I need to upgrade valve springs. Well my friend is selling me valve springs, retainers, and +1mm valves from patriot performance. I don't really know much on gains from upgrading valvetrain, I know for sure that its gonna be stronger but will I see any hp gains from this. I've been trying to find good reading material on the internet but I can't find anything that gets down into detail.

 

what size pulley are you running?

 

Ummm you don't need to upgrade the valve train cause your running 14lbs of boost. You need upgrade valve train if you plan to run any hight that 7,000 Roma cause you have a high chance of floating a valve around 7,300rpms or higher.

Then a gain you have a 2.4 and I just noticed that my bad brotha I keep thining you got the 2.0

 

ZZP didnt worry about upgrading the valve springs in their turbo 2.4 until they were into the mid 300 hps range which your not close to so i dont see why you should be worrying about them at this point

 

Unlimited is right they didn't do you plan on going past that right away?

 

I'm running a 2.8, I plan on getting meth with income tax along with some other bolt ons. I won't be installing the valves and all those goodies until after may 1st. I would install them now but I don't want any horror stories before the lone star bash that is coming up.

 

Springs are a good idea anytime you start running higher boost and/or more RPMs.(stock springs are, well stock. LOL)

Not sure if you are aware of this or not but you cant just "install" +1mm valves......

You have to have the valve seats machined to accept them. this means taking the head off, completely disassembling it and going to a machine shop.

 

yeah my friend works for a chevrolet dealership, and when I take the head off he is gonna take it to work and send it to the machine shop they use and they only charge 160 to assemble the head and do what they gotta do for the valves. I'm also gonna buy arp head bolts as well, when time comes to put this all together.

 

hEck good deal man

 

its going to allow you to run a higher RPM, if you dont upgrade them you will get valve float at high rpm's, but its all about how much you want to push your car

 

good post joe maybe i can get some info from this tho. but for my 2.0 lsj guys lol

 

upgrading valve springs is needed for the lsj anything over high boost or reving over 7,100-7,300 for valve float in an lsj is know to happen at aout that rpm point, if thats what you needed to know rico, just throw it out there if you did or not .

 

i wanna rev 7500 atleast on turbo

 

then your going to want to upgrade your valsprings with either zzp 78lbs with retainers, or the super tech 78lbs you'll be good to 8,000k for sure i dont know what they are good up too

 

8000k for ***** and gigless

 

I seen some one run. 9,500rpms on a balt

 

paul? lol

 

so on my le5 with the new valves and stuff, what can I put my red line at?

 

while the heads off u mise well get it ported... while its at the machine shop.

 

I can't find one that does port and polish
