pics how it sits now

 

Word?

 

Nice, what turbo you running?

 

Stock internals? I don't see It last to long with 300hp

Also post pics man I wana see

 

waiting on pics and vids too, i like seeing what people put together

 

i got a built engine for ya...good for about 500hp.................and, yes gents it is a shameless plug.

 

cool story bro? pics

 

Pics or it didn't happen

 

300 seems like a lot for 10 psi

 

sub for pix and videos

 

pics ya ricer.

 

pics?

 

!!

 

good luck blowin it up soon with stock internals

 

ill check out the videos when i get back to my room, but what turbo are you running? you say 50mm but that doesnt really help out with exactly what it is.

and yea, id suggest getting forged internals as well. they wont last too long. is 300hp dyno'd or just what you guesstimated?

 

This. I want to see legit dyno numbers

 

I dyno'd at 255 last Aug and I have a lot of mods and running 10 psi. look at my vb garage if u want. I have a bigger tb now since the tune so I figure I am a couple more ponies than my dyno numbers. I would suggest u are around my hp #'s unless u used a manual boost controller to get close to 300 hp but ur internals will not last long at all.

my setup has lasted 3 yrs for me! stock internals. (I will not build my motor, so when it blows, I will put another stock one it and move on to a better vehicle capable of more power and less $ to get there

edit.. my only hp restriction would be my 2.5" catback but I am running that for better gas economy than my previous 3". I do have a 3" catless dp tho.

 

i already purchased my internals eagle h beam rods wesco 9.5.1 compression i only need a cometic head gasket and arp head studs and bigger injectors for e85 why everyone talk **** ecotec are boss!!!

 

do you have 2 accounts?

 

haha what? ^^

 

9.5-1? Never seen those... No one's talking **** dude. People are trying to warn you that you will blow your motor on that much power is all... And Idk if you noticed but we all have ecotecs...

 

and were all boosted well most anyways.

 

sleeper to the max!

 

Most

 

i have an ecotec engine builders guide also just like all of you it will hold up i don run it hot at all and my tune is really rich so i think ill be ok for a few months till i build it sorry i ment 8.9.1 at stock bore 86mm
