Hey SC, just curious to see what people know about building a monster ej with the attempt of making atleast 400whp, once I'm on my fulls I'm going to convert my gen 2 liberty rx, atm I'm thinking of the ej257 with forged internals, port and polished v4 sti heads and stage 1 cams running bigger injectors, bigger fuel pump, bigger turbo (roughly 20psi).
Everyone's opinion on this would be great.
Cheers, Joe

I'm pretty sure JRod has a monster EJ already done he is selling?

[nickknack]

some info here http://forum.liberty...hp?f=18&t=23280

[Josh.]

I hope you have a monster gearbox, brakes and bank account.

read this thread before you even consider it.

If you still crazy enough to consider it talk to vicelore first hand. no offence to vicelore he has one sweet ride but for what he could bought for that money is crazy.

Buy Jakes, $16000 and its already built ready to go.

Was going to say, buy Jakes car. It's already done and still has potential. I don't think its fully tuned yet either from what I've read.

So 300kwatw?

 

Big problem with a ej257 block is the bores are very thin causing alot of bore flex. This in turn causes head gasket failure, uneven bore wear and even total failure of the bore. The use of e85 can off set this a fair bit but for that power range your looking at dart inserts and a closed deck (AKA $$$$$).

 

Have you thought about a ej22 block? Put a gt35r twist mount on a forged ej22 with sti heads/cams with e85 and your safe to boost it to 20psi+ and not stress. If you realy want you can fit a ej257 crank to the ej22 block!

 

Ej257 are nice motors but you need coin the keep them safe over 250kw.

[SC00BY]

I was doing some research and from what I've read, a closed deck ej22 with sleeves and forged pistons, rods and crank can hold some serious boost

[CodeBurn3r]

Ej22 forged with v3 heads and maybe a 257 crank gets my vote.

As Cameron said... Look at what vice went through. . But also if you are going to do work yourself. Things can be cheaper..

Vice was in a spot of not knowing a heap about subies and engine building. A very expensive lesson learnt though..

Buying power vs building power.
Remember the 3 key factors. Cheap Reliable. Fast. You can choose 2 and only 2.

i would buy this

convert the interior to series 2 ie black and put an rx/gtb kit on it. fix the issues and when/if you blow it up chase some power with a build ej22.

 

i think this is an absolute bargin

[SC00BY]

Mechanical/labour work I get for really cheap and close to nothing, so really it's just the costs of the parts that will set me back, how much do ej22 blocks go for?

Quoted for the win!!!11

[jakefake]

Saw your sale thread, seems abit expensive though :/
I can get a closed deck shortblock ej257 with the following features:


Reconditioned Block Halves
Closed Deck Process to Block Halves
New 09+ EJ257 Nitrated Crankshaft
New CP Forged Pistons
New CP Rings
New Manley H-Beam Forged Rods
New ACL Race Bearings

For $5500 and im sure that'd be able to hold some decent power?

[dja]

Agreed, the only thing i would add to that is some sleeves.

 

If your close decking, and chasing big power do it now, its not expensive, and gives headroom.

[SC00BY]

Yeah some sleeves would be good, but then what heads to use :/

[jimmyg]

The v4 STI heads are fine.

 

PS1000 with an ethanol sensor. Some ID2000 top feeds and a twin scroll housing on a GT35R would put the icing on the cake.

 

[SC00BY]

I was thinking stock turbo and bigger injectors for the run in
