this has been driving me nuts trying to figure out which ones I should go with I have heard good and bad on both cams...for one the 402 are turbo cams so thats a big plus but would I HAVE to run springs and retainers to make 400+....thanks for the input guys...

tannerLSt

BOTH of them you have to run springs/retainers...

T9U4ReBgO

ok well that solves that problem now which ones should i go with?...and i seen a video where some had stock head with the 402 and made 400?

if u are keeping the stock ls power band stay with a 402 if not than 404 would be good just really depends

yea good luck finding someone around sc area that can tune those cams. u have to dial in the cam gears too correct.

T9U4ReBgO

the 404's because they are a agressive na cam. the 402t just valve train. as far as i know they have a good power band up till 8k...... so i've been told

T9U4ReBgO

so ur saying u would recommend the 402t i know everybody has there opions but honetly i have been leaning toward them...i really wish i didnt have to do springs and retainers i mean i know its better and u have to but im trying to build this car as cheap as possible to kinda prove a point lol...i only have 500 in the car right now with the ls swap in it and i already have a built bottom end so right now im sitting pretty good but i still need the head done and to peace together a turbo kit....but hey thanks for the help man

build it because its what you want. not because your tring to prove a point of how cheap you can build a car.

with that being said get the 402t you should be able to pull around the 400whp mark. BUT its going to take you around ~20-23psi on a t3/t4 with around a 57 or 60 trim

T9U4ReBgO

yea i was really leaning toward the 402t...i was thinking of going with either a holset or a borg warner....like maybe a hx35 or 40 and someone recommend the borg s296 with either of these turbos do u think i would have to run that much boost also...??

T9U4ReBgO

not 296....256 my bad

bigbadboy

T9U4ReBgO, which part of greenville are you from?? i'll send u a PM with my #. just go ahead and go with the 404's you'll be happier. i'm abt to put a pnp head on with those cams. Thai at 1320 is more than capable of tuning the LS with those cams. he has done some before. and he is local to us.

the holset line of turbos make great power and are cheaper than the borg warner line. if you look into getting a holset turbo make sure to get an exhaust turbine of 12cm^2 - 16cm^2 the 16cm^2 maybe the laggest on a 1.8 motor but it makes power. borg warner also has its reman. version of holset turbos also

redlsvtec4door

i had crower 403's in my ls and i took them out when i boosted because it was losing boost, thats my frear with the 404's. im going to do the 402t's. plus out of boost preformance on the 404 has to suck because its more of a agressive cam geared for high rpm.

also both cams were tuned by tempest
403's 180whp (would only hold 5psi steady on a 7 psi wastegate. no leasks
in the system)

stock 214 whp (low, 7psi) 286 (high, 14psi)


also some thing to keep in mind about the spring and retainers issue is the 404s will definatly need them due to the huge lift and more rpm they need

the 402t are alittle more agressive than stock and have the duration for a turbo car. as long as you dont rev past 7500 the stock s&r will be fine.


i ran my 403's with stock s&r and only reved to 7500 and they were fine. plus ls motors are cheap, its not like a type r motor.

T9U4ReBgO

well what reason would i need to rev an ls past 7500 to make my power...i mean i dont know i may need to and in that case ill get s&r but if i can get away with it i just wanna do cams...

T9U4ReBgO

bump

T9U4ReBgO

???

quicksilver1689

just get cam gears if your in doubt about duration and the boost situation

T9U4ReBgO

Imma getting cam gears regardless...are u saying get them for the turbo cams?

bigbadboy

if you put any kind of cams in there your gonna have to tune the cam gears regardless. if you really only looking for 400 and you really can't decide on valve train just keep it all stock and just boost. i make 400 with my bone stock LS revving it to 7500 everyday

T9U4ReBgO

when is all ur power coming in
