B18a1 Block
Scat H beam Rods
Arp Rod Bolts

Gsr Timing Belt
B16 Water Pump

Acl Race Bearings
New Main Bearings

Thanks in advance let me know what you think.....the turbo i am buying is a garrett t3/t4 57 trim..

 

No.

 

Why not get your block sleeved while you're still dropping all that money? I don't see a block holding together more than 15 psi and you're going to need well over that to put down 400 hp. I'm not 100% sure on your turbo but I would maybe use something a little bigger?

 

my stock b16 held 16psi daily driven...if you look at the dyno graphs jeff evans has theres similar setups holding over 400whp easy...and stock sleeves are proven to hold up with a good tune...

 

i forget what magazine was doing it but they were trying to see how much boost a stock ls motor could handle...i believe it withstood 18 psi before it blew

 

yes, as long as a good tune is provided your motor will hold that fine.

 

btw what are you going to be using for fuel management?

 

well on my b16 turbo i ran chrome and i was pretty satisfied with it...so either that or ill try uberdata

 

injectors? fuel pump?

 

i have a walboro 255 fuel pump and the injectors i have are 450cc bluetops....but i think i might have to get 550's for 400whp

 

yeah id at least get 550's maybe larger if the price is right.

If you're going to Jeff Evans, ask him about neptune...i know he's all about that. He's a great tuner though...he tuned my setup (Apexi Power FC).

i don't believe he is going to jeff evans, i think he was just mentioning that with a good tuner that his power goals are achievable wihout having to get his block sleeved. i do agree with you that jeff evans is an awesome tuner and does some awesome work.

 

i would defeintly have jeff evans tune my car...but the waits are insane....its like a 2 month wait to have him tune a car.

 

there are tuners putting down 500hp on a stock b16 block, no sleeves no guard. get the tune right and yes it is possible. make sure you have all your supporting mods and stay clear of that good old detonation i dont think pump gas is gonna cut it

 

well where i am there is 94 octane...so i think that should be fine at 400hp...

 

On page 1 of THIS thread there is an LS making 373 HP at 18 psi, however it is on a 60 trim T04E. It's only a minor difference, so your power goals should be reachable at around 18-24 psi. But IMO, that's pushing the turbo pretty hard.

You should read up on that thread since there's about 38 pages of turbo B18a/b setups in there. Also I think you should go with some 650's or even 750's since it's only $30 more for those two. Check out http://www.rceng.com and look for the formula on how to calculate the injectors HP limitations.

 

i doint think 400whp is possable, but above 350 whp.

about getting your blocked sleeved.... if you dont wanna drop a couple grand into sleeving it... just fill the block. its much like a block gaurd but it cost about 30 bucks. pretty damn solid. if done right you can boost way over 20 psi.

or you can post your block, but i would recomend filling it other than posting. posting can cause stress on the stock sleeves, considering its only supports a couple sports of the sleeve, while filling supports the whole damn thing

not sure if your a member of http://www.homemadeturbo.com or not but there are awsome white-ups on how to do both things

when i get around to building my moter im gunna fill my block, and 20psi DD here i come

also: a member of HMT dynoed his car i think 430 hp, and 289 tq or somthing, built b16 with i think some minor head work, with a FILLED block, 30 PSI. cheakc out the how to's if your not a baller like me

So why did it blow?

I don't understand why everyone says these huge boost levels will 'hold'.

Of course they'll "hold" for a short period of time.

Who's got 300-400 WHP on a stock block for 20K+++ miles?
