and that was on the run-in tune running around 15psi

The owner is thinking of bringing it out to a dyno day in 2 weeks time and by then it will be run-in and hopefully had its proper full tune.

This one is hybrid of SR20VE 20V head and SR22DET RWD bottom end

Its a shame such a potent powerhouse from Nissan did not end in a S car. Potentially dwarf the i-vtecs by miles!!! :nod:

A 20 valve head? You sure?

And why use the VE head and not the VET head?
no it is name of this head, basically it is still 16V but it is new type from primera P12 and it is called 20V

it is just easier to source VE head then VET :nod:

Random lots of questions:

Are parts from a DET head & the VE heads interchangeable? As in are the bolt patterns the same for inlet/exhaust manifolds?
What about oil channels from an SR bottom-end, does the VE head need more drilled?
What kind of management do they take? PowerFC's?
So is that a "normal" bottom-end and the head's just taken from a Pulsar VZR?

I'll try and answer some of these, as I was speaking to the owner about it as I wanted to find out exactly was involved to see if it was worth doing on my car

Random lots of questions:

Are parts from a DET head & the VE heads interchangeable?
I am pretty sure the answer to this is no.
As in are the bolt patterns the same for inlet/exhaust manifolds?
The inlet side is huge compared to a STD sr20 head, so you need to use the VE/VET inlet runners. The exhaust side is "close" to STD, so you can get away with enlarging your exhaust manifold ports if your too cheap to get a custom one made up.

What about oil channels from an SR bottom-end, does the VE head need more drilled?
There are certain holes which need to be welded up etc. I can't remember which ones they are though.
What kind of management do they take? PowerFC's?
You will need to run something like a Motec/Autronic/Haltech. They originally tried a PowerFC with an external vtec controller thingy but found once it swapped onto the larger lobes it would jump off the maps on the PFC, so they upgraded to a Haltech.
So is that a "normal" bottom-end and the head's just taken from a Pulsar VZR?
It is as normal as stuffing it full of parts from a Tomei catalogue, and then custom mounting the VE head on it. There is a lot of custom work which needs to be done which you don't see in the pics like custom engine mounts as the head sits higher than STD. You will also need a bulletproof gearbox, and a BIG turbo, as at the moment JoC reckons the 3076 on his car is a bit too small and doesn't have enough flow for the head.

OK, Im still not convinced by all this information.

What modifications have been done to the rear of the engien bay/baulk head? Thats a 20V head (Ive done some research) and found that that is a FWD engine and the CAS is on the other end of the Exh cam.
Here's a pic of a 20V VE. You can see the factory inlet manifold.



Here's what Wiki know:
http://en.wikipedia.org/wiki/VVL

That explains the 20V term a bit better.

From Nissan Globals site about the X Trail GT: "The turbocharged GT model, scheduled for release in February 2001, is powered by the newly developed SR20VET engine. This 2.0-liter 4-cylinder engine is the world's first turbocharged engine to incorporate a variable valve lift and timing (VVL) system, enabling it to generate 280 PS (206 kW) of power for exhilarating acceleration. In addition, torque output in the low to medium speed ranges has also been increased for improved driveability in urban areas as well."

But even in the Xtrail its a transverse moutning, so Im a bit miffed about the fitting in a RWD application, as Id previously been led to believe that the XTrail GT used the engine in a longitudinal layout.

But its not

there is another problem except CAS which can give you issue on the back, VE solenoids :wave: two in old version of VE head and one in 20V. Don't forget oil pump body as well, which doesn't fit.

Inlet is most probabally custom made :nod:

I heard that you'd have to drilled a hole in the bottom block for the oil feed to the VVL.

That looks like a custom plenum

It's not a 20 valve head, it's just a code for the 2nd generation VE head called the 20V

The SR20VE 20V head is easier to come by and cheaper, if you are using the Xtrail's SR20VET, you will be paying big money for something which is relatively the same, there are some minor changes in the SR20VET head but does not justify the money you are going to pay for it

I think you need to relocate the CAS as well cause it's hitting the firewall if you put it straight in

^ Thats 390bhp at the rear wheels on a Dyno Dynamics machine which equates to about 429-468bhp at the wheels on a Dynojet Machine. Seriously this S15 is impressive.

Call me stupid:wack: but whats the difference between the dyno dynamics machine and the dynojet machine??are u saying that the dyno dynamics is more accurate or what? whats the difference between the 2?? sorry for the off topic lads..
