950HP AWD Silvia | SR20VET VS SR20DET Heads [TECH NUGGET]

What's so good about the NEO VVL head vs a DET head?
Footage is a small cut from this full interview: • [TECH TOUR] 43 PSI 950...
Sporting 950 WHP @ 43 PSI of boost and an 8.54 @ 164 MPH ¼ mile history, this 4WD converted 2.2L Nissan S13 Silvia is one of a kind and unbelievably still street legal! We caught up with Paul Torony of PJs Quick Bits at the 2017 World Time Attack Challenge to go over this weapon.
Converted to 4WD with street drivability in mind it runs Nissan Skyline GT-R front differential and driveshafts via an RB26 sump and adaptor plates. The car also uses the ATTESA system from the GT-R where a centre differential splits the torque and is adjustable via a Full-Race Motorsports ETS-Pro controller setup. The main brain of the operation is a Haltech Elite 2500 which controls the amount of boost the Precision 7675 Sportsman Gen2 turbo produces according to speed which can easily be adjusted via a Turbosmart E-Boost controller from the driver's seat to match conditions and/or preferences.
The SR20 engine has been built to last with a forged bottom end, Kelford cam, 2.2L Brian Crower Stroker kit, NEO VVL head from a Nissan Primera P12, CP-Carrillo rods and thick wall pistons and a custom Billet CNC block. The power produced makes its way to the ground via an OS Giken OS-88 6 speed sequential gearbox which is helped by a Geartronics flat shift box.

I remember when 950 horsepower could only be seen in a massive turbo Supra or a gnarly V8. Now they’re making that in a little 4-cylinder that sees a lot of something called “killawmuters” on the street. Knowing you’re Australian, I’m guessing the Killawmuter is a venomous creature with a bad attitude.

[@skippy2987]

They are from New Zealand. This makes their knowledge of venomous creatures limited to stories their grandads brought back from training with us in the war... There's basically nothing deadly in NZ that wasn't introduced

[@hpa101]

I had a watermelon go off in the fridge once that looked pretty venomous @Skippy. NZ is a dangerous place ;) - Taz.

[@rayscar6390]

Did he realy said "V-Tec" standing in front of a Silvia?! 😅 but you are right with your comparison. It is like it is! No matter what you call it.

[@goldenvtr]

its not v-tec is vvti-l, because toyota :D

[@Kaesk3]

VVL all the way, up the VE motors!!

[@SR22VET-S15]

it basicly is vtec, works in the same way

[@victorrodriguez-ix9ys]

What a great project !! Greetings from Costa Rica !! Btw I loved “don’t say dirty word “

[@bradpittman5075]

7675 is a great whistle. The newer 6870 seems to be proving itself a beast as well. Crazy efficient turbos now days. Very very cool.

[@snackbags]

Would love to see a clip of this in action in the video. Great vid as always. Thanks!

[@Marko-JZX100]

What is the idea behind dual 4-port solenoids for boost controlling? Does this give any advantage compared to single solenoid plumbing?

[@adharuddinabd.rahman4521]

Can anyone help me with what the guy exactly says 1:16 until 1.22?

[@locosvatos2391]

2:29 lol

[@AshtonCoolman]

Is that Adam Neish in the background?

[@skippy2987]

Being interested in head porting, I'd love to see a comparison on these two heads.

[@DodgyBrothersEngineering]

The comparison is chalk and cheese... Think 2V and 4V Cleveland heads, that's the kind of difference you are talking.

[@skippy2987]

So one is slightly too big and the other is massively too big?

[@DodgyBrothersEngineering]

@@skippy2987 Yep a bit like that :D

[@SR22VET-S15]

standard ports will still make around 800whp, they have insanely high flowing ports

[@skippy2987]

@@SR22VET-S15 Unfortunately quoting power levels as airflow on a forced induction engine doesn't mean anything, you can always just force more boost through it. Airflow (preferably in cfm) and cross sectional area are where it's at, with those two you can calculate the engine's characteristics pretty effectively Port velocity (proportional to rpm and inversely proportional to port cross sectional area) is almost as important as cfm, it can (assuming correct cam timing) give you as much extra power/torque as another 2-3psi.

Building one myself now with taarks and mazworx parts. P11 head

saw the thumbnail, but didn't actually get to see it run. lame

[@d3tach3d]

Why does everyone shit on VTEC when the dual lobe technology was actually created by them and everyone copied it. Give it a little more respect. without that sort of tech your motor is only good in either low or high rpm

[@holeshot282]

We use what they call killer cams in the VE head so we dont use vtec, useless for drag racing.

[@d3tach3d]

@@holeshot282 Ive seen those before. From what a remember hearing, they make great parts. I know Drag Cartel had/had been fucking up this last year+ with some of there Cams and other products and intern they lost alot of fans/customers/etc). Since they seemed to always have great performance parts that were "affordable" for what they could do/handle. o\On top of that, they had a huge influence in the Racing scene. Idk, if they changed their manufacturing process or or their Quality Control took a shit, idk. Im not even sure how they are still doing and if there place in the racing scene is still lower or if they've grown. A lot of other great companies have come since them and are making great products. Motion Raceworks for an example. But any who, Thanks for he reply, Brother. Have a good one.

[@igvtec]

That's right like Honda go the honda good on you Nissan trying to copy.lol

[@MR-SR20]

Nissan trying to copy honda? Honda copied nissan after nissan perfected the vtec system honda came up with the k20 engine. The k20 uses the same VVTLI system as Neo vvl from 1997 but k20 never came out till 2001

[@igvtec]

@@MR-SR20 with the cam gears perhaps but Nissan copied the cam setup.

[@MR-SR20]

@@igvtec there were other companies using the VTEC system before Honda but just never publicised it like honda. Honda Nissan Mitsubishi Toyota have all used it hell even the germans used it
