well.. ill tell you right now, that the shop isn't gonna really have a clue what they would need to do to safely run 300hp. they will either do a build based on some other 4 cylinder, or they will over-build it and you will end up spending a TON of money.

are you wanting 300WHP? or 300BHP. without opening up the motor (depending on mileage, compression, etc) you could easily run 300BHP daily.

for 300whp, i would recommend a set of forged pistons, and while your add it, misewell have the rods cleaned up and use ARP rod bolts.

and if you are planning on using a GT25 turbo, i really hope you arne't expecting 300WHP. a i don't even think with a t3 super 60 that you could hit 300whp. you might be able to with the super 60, but you would be pushing like 20+ psi.

and where can i get forged pistons from and the arp bolts

SOCKS_old

ARP bolts. i believe there is a link in the ARP hardware thread.

and get pistons from weisco. i think they are around 440$ shipped or something.. i would get them in like 9:1 compression.

*shameless plug* I have a brand new SMT-6 Tuner kit for sale for 425 Shipped in the US and 450 Shipped worldwide if any one is interested. smile.gif

maybe your talking about gt2540?? because I think a gt25r (also gt2554r) turbo is rated at 250hp or so, so I am assuming a gt25 has a lower rating.... i'm not sure about exact figures but from what I know 300 cannot reached with a plain gt25...

get something like a gt2540r, as our 4G63 had a quite good powerband with this before...

may I ask, how much is the gt25 going to cost you? smile.gif

well i dont have a break down on everything yet... its just all going to be incorporated into the price of the whole turbo setup and install... im curious... if im running 300ish HP do i need internal work? does anyone have experience with this power on their tib??

mwood

dude its proven with a good tune that you dont have to mess with internals...

tdonnell, even though he has not dyno his tib...on the butt dyno he is about 300-350, and he has not mess with the pistons or rods...just a built head...

there are even more then that has not mess with internals...that question has been asked so much

tibbymat

lol... ya i thought i heard it a couple times on here but everytime i talk about my car to my tuner buddys here they call b/s on that.. they say im gonna f*** my motor if i dont do internal work but i only listen to the proven facts and experience! my goal here is to build a 12 second tib. but i know with my altitude its goin to be hard.. but i want it to be somewhat obtainable...

mwood

i here it alot as well but i just like at people and all i think of is "you are fvcking retard and dont $hit about hyundai's"

that is why i love this car, it might not have alot of aftermarket support but we do what we got to do to bust another car ass at the track...

good i hate hondahs

the only thing that I can see you gaining from buying a set of good internals (besides having a more bulletproof block) is that with the lower compression ratio, you can run a more aggressive timing on the engine with a lower boost level so you don't stress the turbo much.
