should i increase my rpm limiter with the mods i have (in my vbgargae for current ones) and im getting probably the 2.4L/LSJ manifold in the near future (once i get my car fixed and a few $)

i know the cams and intake mani will have more hp in higher rpms so i figured id ask to get some advice

 

The big factor will be the cams. Peak power will be determined by the specs of whatever you choose. The 2.4 manifold will help up top as well, but IMO the cams will help more.

BTW, how are you running stage 2 cams? Don't you need tuning?

 

yea i know the cams help more but just with the powerband shifting to higher rpms would it be smarter to move my rev limiter up some?

 

Yes. The stage 2 cams should be good up to ~7500 IIRC. If you have valvetrain work, I would take it all the way up to that.

 

You would be able to use the power that's shifted upwards then... It would be beneficial, as long as you have the valve springs and retainers to go with it

 

all depends on where peak power comes in and falls off.

stick it on the dyno

 

i am going to be once i get my car fixed (coolant leak) but just wanted opinions for it and if stock springs/valves would be able to handle it

 

For what you have done now and invested in the motor... i would save your pennies for valve springs and titanium retainers first. No use in blowing the motor when it's preventable.

 

thats what i figured

wheres the best place to get them? ttr?

 

That's where I was looking at getting mine. They have the option for the titanium retainers.

How much power are you getting out of the built motor now?

 

lol i will let you know when i get the damn coolant line fixed and take it to the dyno... id say prob 200whp ish (with the 2.2l beta tune)

 

check out smg, hes got a 2.2 running to 8500, with less work than you have done but i know the valve train is built.

the only reason i dont want to run past 6500 is cuz of what i have done and the stock valvetrain... im tryin to get money saved up for it.... soon

 

you got the rest of it ready now do the valvetrain and get that thing in the 13's on all motor

 

haha thats what im trying for... i was a 13sec all motor 2.2

and i got stock bore and compression

that 1/4 vid seemed like only a high 14/ low 15???

 

should i change to a .20 over bore or 10.5:1 compression???


do i NEED titanium retainers and seat locators???

 

IMO you aren't getting into the 13's n/a with stock compression.

 

im most likely going to bore, i need to find higher compression pistons though

LSJ is same bore as 2.2 right? are the rods different lengths?

 

Yes, I believe they are the same bore.

You'll probably have to go with some custom pistons for the higher compression. That is of course only if you have put the idea of a snail out of your mind.

 

yea im almost positive that i am not going to. thats why i have the pistons still in my car now cuz i wanted to but $3700 for like 100-200whp is kinda outta my price range when im not going to keep this car more than a few more years

 

Wait, so do you have the forged rods and pistons in now, or not? I'm confused by your sig.


If you do, but don't want to drop too much more $$ into it, (Like for a turbo setup) I would just throw a 125 shot into it and call it a day.

 

i got all forged. i have n2o also which i am going to use at the track but if i go all motor i wanted to up compression and bore. i can get my money back for the pistons i got in the car now

 

would i need a wideband for an n/a build? and how much hp will the 2.4 intake manifold hold?

anyone with info/help/advice????

 

What lb springs should i go with? 76, 78, 94?

I was thinking 78

i am also boring the motor .20 over

 

with higher cylinder pressures comes power.
