2.35L VVL motor with 91mm stroke and 11/1 compression is in production

[Jason@JGY]

We are building this one for a favorite customer out of NY. This one should easily break the 200HP mark with NO bolt ons :-)

Keep me posted on this Jas, because for me I'd drop some DET pistons on that motor but I'd only want a 87mm bore max

[Jason@JGY]

dropping the compression to 8.5 from 11/1 would make less horse power than original and would not be a good idea

good try

[GregG20ConwayDubFace]

Oh the n/a is not for me, I would use the 2.35 stroker crank and beefier rods with turbo pistons & an 87mm bore. However this would not yield 2.35L because it takes both bore and stroke make displacement.

But for me I would use it for boost, not n/a so with an 87mm bore this may be about a what 2.1L I guess? However Idunno what I will do you know I am confuded. . . . -Me:(

I still have yet to truly understand the fascination of turboing VE motors. Traditionally, dollar for dollar, it's cheaper to turbo a DE from the US and you can make the same if not more power and it's traditionally more reliable. VVL Nissan motors are somewhat comparable to Honda vtec motors in the issue that they make traditionally more HP than a non vtec motor of the same displacement, yet very little more torque.

The trend of turboing those motors started because of the lack of turbo'd counterpart motors that were available in the US. This is not the case for us.....as we have DET's that can drop into our chassis with no mods needed for $1700 from JGY.

There are some really good technical articles in some of the magazines such as Turbo and Dsport that discuss how VVL and Vtec may be great for NA applications, but for turbo.....sometimes it can be bad.

On an high output NA application, you traditionally have the intake valves barely open before the exhaust valves fully close.......this helps scavenging and venturi properties in the combustion chamber.........the idea that as the gases are moving out of the combustion chamber, the issue that the intake valves are barely open helps create a draft and pull or at least start the process of getting the intake air in the chamber and hopefully close the exhaust valves before the intake air hits those valves........ Hopefully most of us understand that........ Now lets make the intake pressure go from 0 (NA) to 20psi (turbo) and apply those same cams........scavenging in this case may actually help you lose some of the intake air out the exhaust valves before they close because of the pressure of the air WANTing to go into the combustion chamber. It's not a gaurantee that this will happen, but just turboing a High Output NA motor is not a gaurantee that it is a good idea. Yes, the turbo will make more power than not, but you may be wasting some of this power due to cams designed specifically for NA applications. You need to know about the cams and what their properties are to be sure. It's like those guys that you see that have "Tornado Intake" stickers and "Borla" stickers on their Chevy S10. To them, spending $300 gave them horsepower. But did it?

So let's say that you turbo a vvl and play with the cam timing and change the cams enough to fix these issues..............why start with a VVL in the first place?

I'm running a bone stock Avinier DET in one of my sentras......with our JGYBB37 (GT2871r), our rail and injector kit, and a 300zx maf. At 22psi, I'm ROLLING. I would say that on our dyno I will see about 330HP at the wheels on this Mustang Dyno. Realistically, that is about 380HP at the crank and is about as far as most of our customers can take it due to transmission limitations. Not to mention that much HP over that amount it takes more driver than HP to make the car fast as we are traction limited.

Does jgy have the stroker kit and if so what liter would that make it?

Also how much would it cost?

i hope i'm not bothering you, i probably wont buy one right now.

I don't know if i want a turbo or a stroker motor. Thats kinda why i joined this site, cause i wanna learn more about my car and you all have great parts.

as stated in the heading a it would be a 2.35L... we have one for sale if your interested
