damn at those kinds of prices your parts must be gold plated

Cheap parts make cheap engines. Cheap engines break! Cheap parts will cost you MORE money in the end, always!

Mine are smaller then that and making 308 rwhp at 11.5:1 fuel ratio.

It all depends on how good the injector drivers are in the ECU! Wolf Ver 4 has very strong injector drivers. This means they open very fast and close fast, there for delevering more fuel!

Individual mindset is the difference for opinions.
'cheap' has/can be done. 3-400hp starion 2.6 sohc proven on u.s. forums, using $600 ecu and $4-600 turbos. Good megasquirt examples there as well as lots of options. Even stock cam/block/motor standouts (won't get any cheaper than that).
Lower revving motors = less stress, more reliable.

Same approach "should" work equally well on the 2L.
Requires more effort & research on your part, so you can be realistic when you set your limits & goals. Rather than listen to 'perception' you'll see what actually works from what doesn't.

Hard to say what HP an injector can/cannot make.
Fuel pressure has significant impact on what hp an injector supports.
We have an sxoc ca18det clubmember @293bhp from his stock 370cc, no hi fuel pressure either.
Another point to remember is that the sohc powerband will rarely see over 6500rpm.

Why not use of the whole 4g64 sohc motor ??

What are cheap parts ? Eagle rods and crank are cheap.
I`ve made a "wish" list from a 4G63 parts dealer in US, and picked everything brand new, incl new ported head new cams, fuel pump, intake and throttle body, ecu (haltech) turbo (garret GT) cam gears, headgasket, new oil and water pump, injectors (650cc) and fuel rail.
All these parts are top of line performance names like Garret, Aeromotive, AEM, Crower and Haltech.
And still could get the price up to more than 8500US$ wich should add up to about 10 000AUS$ and thats all NEW parts!
Forgot that i picked a oil cooler and intercooler to :)
Don`t want to argue with u guys but just seem to have trouble getting the numbers to mach up

Think im going with the Dohc setup since i don`t need the engine running before the next spring :)

Ask people who have done it. Depends on how "flash" you want your engine bay to look. I can tell you ive spent way over 10k but its going to be a show quality car. And only best parts were used.

It's all well and good to go and buy the parts, but who says they are going to make power? Engines don't work like that! It's not always the biggest and the best, it's how the parts fit and work together.

Also, in your price you haven't quoted for somebody to BUILD the engine either! Are you just going to whip it up in your back garden and hope that all your parts make power? Who's going to tune your engine? Have you set a goal (HP)?

I think there is a lot of wishful thinking...

Hmm...
Don`t gonna argue with u, so just gonna se what happens if i get done someday i will let u know about my results:)

And putting an engine together isn`t that difficult. But the tuning off course cant be done in your back yard..

Since your going custom manifolds anyway so you will need a computer, you might as well use a dohc head.
I would just get it running (without the wish list) then worry about the big money bits later. Like you say they are not hard to work on.

Just a quick question, the water in the doch head flow a diffrent way then the soch right ? how can u use doch head gasket with a soch engine how will the water get around when the holes aren`t located in the right end off the engine ?
Sorry if this has been answered before

Regarding the ECU, i don't think megasquirt is the way to go..

Why don't you try a KMS ECU.

http://kms.vankronenburg.nl/

We've just used it on a 30`000$ engine of a Lacia integrale at work, produced a safe 445hp (crank).

The ECU works VERY well, easy install, good price and fantastic support.

The company is in Netherlands..

Compared to different standalone ECU`s, this one proved that the self learning lambda control worked spot on!!!
