Number one is this a ready built bottom end rods pistons etc.

Number 2 is it just a case of taking the old block out skimming the old heads new gaskets etc and fitting this block in

Number 3 will this evon work with my 99 2.0Lt heads gearbox running gear etc.

Number 4 what power can it handle and is it any good

im basically looking at options looked into forging the original 2.0lt type R lump but want to weigh up my options first before i commit

Help please

What sort of performance are you after mate? 2.5 is a good option depending on how far you'd like to go.

ZippyBobby

400 + not looking on going mental

Thats the way. Im assuming you know the costs involved to reach your target unless you doing all the work yourself? 2.5 with forged pistons, rods & race bearings would make you a strong reliable block.

The engine in link is a OE short block with std suspect pistons.
For 400 hp get some drop in forged pistons, which Mark seems to be offering on the next block down, but with no price.

You can get that short motor through any Subaru main dealer part No 10103AB850 or 10103AB950 £1321.09 + vat.

Dude 400bhp is expensive you will need a lot more than an engine to keep it al together. Good luck mate

Mus

bigsinky

good luck with that one

ZippyBobby

Im aware of the costs of this im just looking at options I already have the supporting mods got a turbo from lateral on the way think the 321 or what ever it's called already have 550cc inj front mount etc just looking at getting engine build I know i can get a built engine from between 3-5k just seeing what my best options would be

How about a 2.1 CDB Stroker from Engine tuner?

ZippyBobby

that would be a good route the 2.1 if your loking for the 400 bhp 450bhp as but then so is the 2.5 i want one of these 2.1 myslef as i think 400-450 is just perfect for the road i ahve heard thou that the 2.5 will go through the gears quicker as you cant hold the revs as long but this is only what i have heard and i take it you have a six speed or you have a new age sti any way

Shaun

Dependant on build, a 2.5 will rev as well as a 2ltr.

happydude303

iTrader: (1)

yeah but that build will cost even more? but yeah i have heard this to i must say ive thought long and hard about the two and ive still not made my mind up

Shaun

Ahhh... you didn't mention the cost side though.

i supose the real question for mr zippy bobby is how much do you want to spend on your engine. how deep do the pockects go : >

bigsinky

that's always the big question. now i am in no way knocking the OP, but it amazes me the number of people who come on here and say i want 400 or 450 hp and expect to expect to get it for £5 - 6K. to get a really good reliable car that has that much power requires a load of cash if you want it done right and don't want it breaking bits every week.

people think these cars are two a penny and movies like fast and furious and the quest for the "10 second" car compound the difficulty. if half these wee lads got into a fast car they would kack themselves at how fast they are. they have no conception of what is required and how much money and how much development time goes into building a project car with a lot of power.

sorry for the hijack guys.

Got my 2 ltr bugeye STi running at 416 bhp probably spent about 4.5k as parts have needed replacing and supporting sundries. Not been rebuilt to-date but am considering for next year as at 97k miles.

2.5 are great engines with the right turbo you don't have to forge it. A 2.5 in a classic with a 20g is perfect and enought to see off 80% of cars on the road. Not much will come any where near you. 450/450 in a classic can be a little twitchy on the road fun im the right hands with the right driver but horror movie for some one who is inexperienced. I went throught standard to stage one running 330 then 390 then 420 now - little over 500 in a classic. Have you had your car remapped maybe try that and see how you go from there.

there

I Agree. However you can say goodbye to the gearbox . Tryed & tested.

Mus

iTrader: (2)

Have you broken the box already Aladdin?

KAS35RSTI

iTrader: (73)

Ye man it broke on saturday night however i have a spare V4 box. You were so right. It sounds like a PPG now

Mus

iTrader: (2)

That's the 2nd time you didn't take my advice, sell the version four and buy a ppg dude. Was u at the strip???thanks for the invite how did u brake it

KAS35RSTI

iTrader: (73)

It was unplanned man. Even i didnt know that i was going to turn up. Could'nt refuse a play against a 355 therefore i could not resist myself. I just wanted to see how long it would last & now i have seen how long it lasted. So next time someone like me turns around & asks me if a sti V4 gearbox can take 400+lbs...i will say no just like you did lol. It was a good experience though . My next experiment will be on a V5/6 sti box

What you doing this saturday coming? I've had inside information that some seriously boosted GT-R Skylines are paying the strip a visit . What do you say

Mus

iTrader: (2)

Sounds interesting I'm up for it as long it ain't too late you guys start at some crazy hours. Lol was there a big turn out and was there a lot of chavs?how did you brake ur box was it on launch or through the gears?

you got too much money dude why dont you just get a 6 speed or ppg problem solved.

KAS35RSTI

iTrader: (73)

It wasnt as big as usual but there was a good few high powered cars out. Totally chav freezone man . I done 3 runs & on the 3rd run in fourth gear. Going to change the box over shortly..

PPG will have to wait as im in 2 minds of getting another car.

Mus

iTrader: (2)

Another car why you only just bought this, you will regret it the only reason I'm selling mine is to get a house. And I'm not selling unroll I get offer on my flat. Don't tell me you want an evo I'll get everyone on scoobynet to stone you to death pmsl

bigsinky

wasting your time with 5 speed. you need a 6 speed full drive train, including half shafts and diffs.

me & an Evo what a guess looooool. Ive had 4 impreza's now & ive already spent nearly 3k+ on this one. Time for a change i do quite fancy the BMW's aswell

Too right mate. But i enjoy wasting time it keeps me busy.

I have an EJ257 With Forged Internals etc...

Still running wit original gearbox!
Is this risky or will is still cope with the power being delivered?
