$3000 to build bottom end any ideas

[greatdanz]

okay i have a genuine Sti Ra V2 thats done 160kms... boosts standard 16psi eng fairly stock, V7 sti ign coils(3 plug), 3 inch exhaust, and apexi air filter kit.

its time for a upgrade....this is my 14th subaru and i'm over the "usual" dumb bolt on go fast bits. time to build something that actually has scare factor! lol over the past week been getting alot of advice from people saying do this, do that.... sort of got me confused! now i know my way around a Subaru engine (had to many to know they are s***, an blown way to many!!) and have pretty much have all workshop facilities in my garage (what Subaru owner doesn't have tools for their hand grenade) an have come up with this....

aim 400hp ETA 6 months starting from.....now!

now i realize that 400hp is alot of power but what i'm planning is building a bottom end that can handle around 500hp

fully closed deck block (dwelled and sleeved)

billet 2.2 stroker kit

race bearings to suit

scat H beam rods

100thou oversized forged pistons

arp bolts rod/eng kit

so far i come up with this.... any ideas would be great an would be a big help thanks in advance

this is just my bottom end build.. still got heads,ecu, fuel, and intake to go... hahaha dumb subarus money pitts!

I agree. Cause 3 grand ain't going to get much on that list done.

[DacerX]

very true im up to 4k and just have the engine, then i need all custom stuff which is like another 5

[greatdanz]

thanks ej257 no thanks the 2.5 in my mind aint as feisty as the 2.0 an it still will have factory internals its not going to handle 400hp.

my block is already done. an ive got 3k just for the parts. priced up 2.2 stroker kit from redline quoted $1193.00 inc new dumb GST increase

for me i given myself six months i aint rich and dont want to "tick/get a loan" so i have to do this the old way SAVE lol

if it aint done by then well at least the bottom end will be done!

[Guest boostcut]

a 2.5 is the only way you will get big power on a reasonable budget.

Not in stock form. But with a massive turbo its pretty good. In fact its better than the 2.0 if built right from what ive seen.

2nd most powerful car in the club ran 360kw atw on a stock EJ257 bottom end if i recall correctly. 360kw = 482hp

[Guest boostcut]

if you dont listen to that^^ time to sell up and buy a hyundai.

doesnt either build require a forged shortblock, a large turbo, fmic and some increased ability for fueling?

agree it would be "easier" to make 400hp on a 2.5 but no more costly than a 2.0 i would have thought.

a 2.0 with gt30 sized turbo will get you there on factory sti heads.

[Guest boostcut]

posibly funky, but a 2,0 is going to be pretty sore after pushing numbers like that.

you know the saying. theres no replacement for displacement, except for cubic dollars

[stira]

For reliability go the 2.5 or a 3l, it wont be being pushed hard then.

If your going for such good gear get some better rods - no point overbuilding the block and having cheap rods.

Billet stroker kit - what does that mean ?

[ODB]

why not just be done with it and get a 3.0!!!

twin turbos and boom!!

DAMN IT SOMEONE BUILT ONE!

Its as easy to get 400hp from a 2.0 as a 2.5.

I'd say its cheaper to get 400hp from a 2.0 than any other block.

The 2.0 just takes longer to spool up !

[ODB]

the merits of 2.0 vs 2.5 hav been discussed endlessly on here.

We really need a search engine on this site.......oh wait!

i wouldn't have thought 3k would get you all of what you have in that list, unless that sleeved & dowelled block was really cheap along with the stroker kit, what type of sleeves are they.

I'd blow 3k on some CP pistons, Ross rods, machined closed deck block & bearings, & leave it 2.0l

[G-unit]

will ask a mate what his setup is,he has 317kw@wheels on 24psi, and still 2.0, but i think his cost were abit, 6speed aswell etc

[BC5RA]

Open deck 2.2 with forged Pistons and standard shot peened rods with uprated bolts.

Bolt your heads on and 20+psi.

My bad. Wonder what the spec of the kit is.

[Guest]

your right tho - that block would be fine for 400hp and offer better performance
