Its a billet lower section with a greddy s14 intake !

Oh woah, that is fucking awesome!

pretty cool but the hyper tune manifold is best!

Shame the intake runners are so short, I was really considering hacking up a S14 manifold for use on a VE.

i posted the wrong one.

5. 20V cas (won't clear s14 lhd firewall)
6. Hall sensor kit if you opt not to use 20v cas
7. fwd sr20de or any other aftermarket sr20 cam gears.
8. sr20ve oil pump drive gear or mazworx spacer
9. machined stock pulley
10. plug oil drain port on block
11. plug oil drain port on head
12. Drill and tap oil feed for vvl solenoid. (side of head)
13. Oil feed line to vvl
14. Oval bolt holes on sr20det manifold of choice or build one with ve flange
15. Mazworx oil pickup tube
16. Mazworx or taarks water pipe
17. aem / denso pencil coils for p11 or s15 coil packs for p12 head
18. Head gasket of choice
19. Cut / flip stock upper intake manifold or xcessive, hypertune, mazworx plenum (xcessive / hypertune are the only options right now for p12 heads)

Pretty sure that's about it.

This is a great list, but how come no one talks about ecu choices??

If you are using a 20v CAS, can you not use the stock ecu the sr20ve came with and get it rom tuned?? I personally prefer not to run standalones b/c of price and mainly b/c there are no good tuners here in town. They all want to make max power and can't setup a reliable tune

Also, this is great! S14 intake manifold bolts right up to this it looks like

That's a custom billet job. The VVL intake ports are bigger than the S14's.

2500$ us for an intake / throttle body and fuel rail is way to much for my budget !!!! If i could i would dont worry

what's another 2500 when vet setup is already a big baller set up

[SamsonS4]

All fun and games aside as you are already aware of to build a proper vet setup is some big money and down time.

Def not a set up if budget minded is your game but no expense spared maximum power and response is your game. I read about in aussie land there was a event there was a rb28 tomei powered car and a sr22vet s15 going at it and the vet set up out performed the r28. Very impresive.

Yeah, I think that's why I probably won't do this. I love everything I've read about the VET swap, but ontop of the cost of doing it, I feel like you'd also need to totally revise your drivetrain & suspension to put all this power/response to the ground, even further increasing costs. Definitely not the route to go for someone like me looking for a simple & mild low 300hp range 240. VET is big boy stuff. But if I hit that point when 300hp+ is no longer enough for me... VET, here I come.

[rbs14kouki]

You can upgrade to vet for reliability too !

I started from scratch with this sr20vet

Sold my racecar that had a ls1 with g-force gsr too buy my house and stsrted this project on the side

A 400 to 500whp sr wont need all that much $$$

PJ's (fastest s13 with a h-patern transmission and street legal tire) makes 900whp with an xcessive intake that cost 300$ compare too all the other option that are close to 1000$ and up !!!


My friend has 425 whp

sr20vet:
Precision 5830
Topmount manifold
Stock head + dual valve springs upgrade
S15 transmission with exedy super single
Nothing to special


And he drives the car every day to work (he will upgrade the transmission when it brakes)

Personnaly I would not built a vet to run a t28 and have 300whp

almost done.....

I notice that everyone talks about the parts needed to make the conversion to reality, but what do everyone use as the engine harness?

Is there anyone other plugs on the wiring harness to run the head which is different if at all different from the SR20? Will the standalone PFC work with the head?

To make the VVL work, will a multi-switch need to be installed to turn it on or off?

I've been making decisions for the last year and half if I should go this route if I'm not hitting my goals just with my SR. I'm looking at what would work to make to a reality if I don't have to much to work with.

What are the options for this?

[jr_ss]

You can use your S13 harness for all the necessary sensors. You'll need to run an RPM switch to control the solenoids.

As for EMS, Nistune or ROM tuning can be utilized.

im doing a completely custom harness, but the majority of the harness is unchanged when switching to this head, you just need to modify it to accept the different coils and ignition box.

Existing engine harness stays the same. A tuneable ecu is a plus. You can use a MSD 8969 to activate the VVL and just wire in the solenoids to the unit.

Another plus that alot have not mentioned is that the VVL head uses solid shaft mounted rockers vs. free floating rockers in the std DET head. The chances of breaking rockers with the VVL head is 0 to none.

The sr20ve stock ecu plugs into S13 redtop/blacktop ecu plug?

[jr_ss]

No, you use the DET ECU with a ROM tune or Nistune...

You'll be running the DET harness and ECU, but have it tuned for your setup.

[Yellow4g63]

S13 ecu run the Nismotonic daughter board. It will kick the VVL for you if you use one of the outputs on the board and run a map sensor and 20X20 tables.

[Ramonesfreak2010]

Decided to mock up the head and manifold on the block for some extra motivation. Been a slow build since I am paying for this semester of college at the moment.

Thanks for your help!

All of a sudden it doesn't look that complicated anymore. lol

p11 head, here I come.

Nope it honestly isnt. Other than wiring in the new Denso or equivalent coils and your VVL solenoids, its pretty much a straight forward swap over.

[s13silvia123]

For the turbo manifold or exhaust manifold, would you have to notch the existing bolt holes to accomodate with the VET head? Does the exhaust ports match with the DET turbo manifolds?

Reason for the turbo manifold is because I don't want to buy another manifold since I am using the PowerLab twin scroll.

[jr_ss]

Exhaust ports share the same centerlines, you just need to lift the manifold up roughly .125". So oblonging the holes is a must if you have a DET manifold. The ports are higher in the head because of the coolant passages and different chamber and valve angles.

[autotechmotoring]

Or there are several manifold options out there already that can accomodate both DET and VE setups

He doesn't want to purchase a new manifold.

[GroundPerformance]

You should really need to spend much on manifolds or relocation blocks to convert to VVL if your not planning to go on monster build. I'm actually doing this now and I will share it with Zilvia on the Builds thread. Just waiting for Admin approval.
