Default Performance intake for SR20VE 20V?

Hi,

Do you guys have any advice on getting 20V intake to perform better than OEM one?

I have 20V on rails to be installed in my NX in a short time. I will put lightened flywheel and carbon clutch at first, then I want to change cams to N1 grind.
After that, I will rise a compression a bit.

I look into 9-9,5K rev limiter setting, so I can run 1/4 as quick as possible with my short (4.4:1 final drive) SR16 transmission.

Ok, any thoughts on intake side?

Roman

We have not even had a 20v in the building before. I really don't have any advice for it. Stateside here..........the 16v is about the only one available.

Could you post some pictures for us to see?

Sure, the photos following.

BTW, it is still 16 valves design. It is known under 20V nickname because of it is found only on JDM Nissan Primera P12, "20V" model modification. It is rare modification 08/2001 - 04/2002 model year.

Internally it is the same as SR20VET engine, the only difference are NA pistons which brings CR to something like 11:1.

Ok, photos of engine head (not mine) and photos of intake (mine) are followed.

...............question...............

In all my years of selling these motors................I don't know how many times that we have been asked if they are 20 valve motors.........after we answer, they say that they will get it somewhere else.

...........so are they 20valve VVL?'s is not, that is just great! not

Jason, they are 16 valve VVL motors. But they are much advanced than usual SR20VE.

that's funny

I bet I have personally talked to about 60 people that have wanted a 20 valve VE, and I have lost the sale because we don't have them. I always wondered how Nissan drastically changed the head design to get an extra valve in there..........it's funny to hear that all those people were wrong

that's what internet forums can do to people.........give them wrong info

so to set the record straight..........are there any 20 valve 4cylinder SR's out there?

There is NO 20 valve SR's at all.

Remember, ALL SR20 engines are 16 valve design.

SR20VE 20V modification has a really advanced head design and a huge headflow vs original SR20VE head.

SR20VE 20V has individual coil packs vs distributor on regular SR20VE.

SR20VE 20V has morse chain vs regular chain on SR20VE.

And many many little modifications which leads to more reliable, more advanced engine specs.

I spent a lot of time looking for one of these motors and could really find anywhere to get one, where did you find it?

Are you confused Jason or just making a point?

Nathan,

I found it at a junk yard in Vladivostok city, it is Russian city situated near Japan.

BTW, I live in Ukraine, it is many thousands miles from US, it is many thousands miles from Vladivostok also...

I have no reasons to confusing Jason. If you have any questions regarding this engine - just ask me.

That's very cool man. When is it going into a car and what are you putting it into?
