This.

SloBaLt RiDeR

if i were u i would go with forged pistons (diamond, Weisco, JE Piston) etc. and from reading the GM build book iam pretty sure the Stock LNF Rods are "weaker" than LSJ.

ARP or Golden Eagle Head studs

Cometic Headgasket

Stock sleeves will b fine for 400 hp, if u want to go higher go with Darton Sleeves

Pauter Rods (badass) rated 1000hp l

axels atleast stage 2 (Drive Shaft Shop)

I would recommend OTTP reverse motor mounts


if ur going to to head work, Supertech 78lbs springs, ferrera valves

(if porting head, i would port exhuast side for higher end power and if intake side might lose low end power)

u can rev it to 8k ( make sure u take out balance shafts and either put in neutral balance shafts or Level zero balance shaft delete kit)

just plan alittle for the future, doing internal work "overkill" so if wanting to up thee power u can, with out having to take apart the motor and due the work twice, and when ya take it apart bolts and gaskets have to be replaced

get a good boostcontroller i prefer turbosmart, like a dual stage. so u can set a lower "daily driving" boost so ur not ripping on the car all the time.

an then set a higher boost for racing

are all this parts out for the LNF motor?

SloBaLt RiDeR

as for turbo was size are u running? i have a Precision BB turbo 5557 (55trim)

an equal length manifold i would also recommend, i have "log style" manifold which is fine for my power goals

u can get just about everything u need from OTTP and Turbo Tech Racing, which are both great vendors and great prices and very helpful. i got everything from them

wiseco pistons are, ottp just started carrying the pauter rods and they should be the same as the lsj ones. contact fast98 for clarification on that. don't reccomend spinning the lnf that fast as the DI will be to slow to fuel it in the higher rpms. other than that if you keep your build in the 400-425hp range the motor should hold for quite a while provided you keep the boost around 22-25 and its tuned properly.

SloBaLt RiDeR

as far as im sure the springs in the head are the same (dont quote me on that) the compression is 9:2 in he lnf and mine(LSJ) is 9:5, but some vendor(forgot who) will make whatever compression piston u would like.


i stayed stock compression, low compression can handle more boost safer

well from iv seen our blocks dont like psi above 25

nevermind about the manifold hahah. didn't expect a cast piece to be as clean as that one is. as soon as i heard "cast manifold" i thought of the stock exhaust manifold on the lsj's....balhfglasdflsdh

Allecotec carries the wisecos idk who else and yes the LNF's seem to be fine at 25psi, but at much lower cfm's than this guys is gonna push with a bigger turbo.

yah these ones are sweet though stainless for good heat retention and won't crack plus good flow, I WANT!

If you guys are really expecting that kind of power... what are you planning for the trans?

ok.. interested to see where this one goes

How exactly do you get a cast tubular manifold haha?

Sounds like an aggressive build good luck cardelino18, but as had been said even if you manage to hit these power level this car will not be a pleasant daily driver.

There's no nitrous. I also believe that ZZP is running their own valvetrain. I'm not sure if they are on stock pistons or not.

yeah im not going to daily drive it with 500+whp... that would be on a high boost... daily drive it in low boost with 430whp-450whp give or take...

blrt

Just go and buy a used C6 Z06, add a few bolt-ons and you'll be 500 whp. It may be cheaper in the long run, durability, driveability...

Good luck with your quest for 500whp. I am pulling for you.

BlackMamba08

500whp and FWD = fail

cardelino18

iTrader: (3)

Really? come on dude stop hating if you dont have any good information to share to this thread please dont comment ....

BlackMamba08

good information? how about this. i dynoed 293whp/323wtq and have no traction in 1st or 2nd gear and when i retune for all the mods i am doing right now I will probably lose part of 3rd gear. Granted these tires arent the best but do you honestly plan on getting traction on 500whp in a FWD car? It's just overkill man. Not trying to hate but i think you need to invest in a RWD or AWD car if you wanna go this extreme. You're going to spend a lot of money and go nowhere fast.

Mnatvyc1223

whet gen is the HKS SSQV btw? the older ones leak something fierce.

Boosted_Cobalt09

yeah the older hks ssqv is known for leaking issues. so hopfulley its new. good luck with the build

The BOV is the III gen....

my car has right now 323whp and 404wtq and i have traction on 2nd gear.....they are called GOOD TIRES.....

when i run this set up i will be on slicks and when im DD the car i would be on low boost....

80vetteL82

No offense man, but I find this REALLY hard to believe....unless if by traction you mean, if you get on it really really easy in 2nd gear you dont spin....if you have 404tq to the wheels and get on it hard in 2nd I dont care what tires youre running, theyre going to be pulverized onto the pavement

yes I know why they did what they did, NO VINCE HAS NOT. He has unlocked some new tables they are NOT the tables needed. I read their post about that and its NOT fully unlocked yet.

Ok found zzp's thread, sorry they used insanely high octance gas not nitrous.

i have no idea my power levels, but I have ZERO traction in 2nd on brand new tires from a roll, and even my drag radials spin in 2nd in colder temps.
