Thread: 2.3L VE Motors Build For Cheap With Mazworx Headgasket

Hey, I don't like bench racing any more than you do... but when you are weighing options sometimes you have to.

you are assuming the head, intake, header, and engine management will all magically come together and you will make 250whp.

It's not going to happen, well it's not going to happen on pump gas for cheap anyway...

Increase displacement and you increase the amount of torque throretically proportionally. If your intake flow limits you to say 220whp then you will not make anymore than 220whp when related to flow. Bumping compression from 10.3:1 to 12:1 will not give you a 6.3% increase in power. maybe 5-6whp tops if tuned well. Bumping compression should give you a % power (torque) increase everywhere.

If you take Andreas' 216whp 160 tq 2.0L setup and add 15% displacement to the mix, it should THEORETICALLY make 248whp, 184tq just from 15%more displacement. That is assuming you keep your airflow to displacement ratio constant aas well as header design.

so what your saying is ve's are held back by the design or ineffiency of the intake manifold, be it a stock ve mani or a n1 mani.

whats the max whp a stock ve or n1 mani can can supply ?

if im reading what youve been saying in various threads correctly, 230-250whp can not be a reality with out a custom intake mani. wich as well all know none are avaliable or even produced.

stratton.

The N1 intake manifold has better flow abilities as well as atomization than the standard intake manifold. They both lack enough combined flow for much power over 200whp (SAE Give or take).

Sure you can increase the compression, reduce friction, increase thermaldynamic efficiency and make a lot more power, but when it comes to making power from volumetric efficiency, then yes, the Intake manifold seems to be the factor that will continue to hold back these motors.

With all that said, If you can not make more power much easier by reving the motor higher because of intake flow restriction, then just add displacement.

After the 20v/N1 cams get developed and produced, I will be working on a permanent Intake manifold solution. I have the ability to get a few welded prototypes made and then get molds made and possibly start casting these intakes.... All in due time though. There is only 2 of us and I can only do so much.

What about sport bike ITBs mated to oem runners + speed density.

I have seen people do the sport bike ITB's and made them work. The biggest problem will be getting the bore centerline from the intake flange of our motors to line up with the bike ITB's. the ZX14R ones would be the best or a set or 2 from a ducati....

A well made intake manifold will be just as good if not better than itb's

Even if this is true (and I have no idea if it is), we're in a budget setup thread so I considered a fully custom intake mani not-an-option.

A Ve can make 230+ on stock n1 manifold but its starving for air as pointed out by snickers.Most people will never make that power anyways . As for intake manifolds you could of used an o2 intake when they made it, if you knew the correct spec's or you can always get an n1 ported from snickers he always have great products.
