The Sr20/Sr22vet thread

[japslapsilvia]

I am thinking about doing this conversions and have a few questions. So if I was to use the P11 head, in order to use a DET ecu (PFC) I would need to run the p12 CAS, and use AEM/Denso pencil coils?
Can I use Splitfire coils instead?
OR
Would it be better to just use the Hall Effect sensor and a “full stand-alone”?

TIA

I'm pro standalone. Also don't waste money on aem coils when you can get a full set of denso coils for $50

Run the p12 cas , your splitfire will work but they wont be bolt-on in the p11 valve cover !! But on a p12 cover its bolt-on

If you wana run pencil coil , you will need a aem twin fire or similar like a m&w ... otherwise you wont have enough spark for more then 15psi (thats what my tuner told me)

As for the power-fc it will work but you will need a window switch for the vvl activation if im not mistaken ! Im not an expert with rom tune / power fc set-up

[rbs14kouki]

As for the water line Teal was asking about ! I run the mazworx water neck / heater hose kit

It seems that everyone that does vvl goes all out on the setup, meaning upgraded everything. Is it not possible to use a stock sr block, or is it that it can't keep up with the power the head can make. I'm not looking to make crazy power, but would like the benefits of the vvl swap.

[jr_ss]

There are some things you can't avoid purchasing. DET bottomends limit you to P11 cams only. Some people want more out of their setups and they go big. You can just swap heads and necessary parts, tune and go though.

[Ramonesfreak2010]

VE pistons all the way.

[rbs14kouki]

Like jr-ss said ! Stock det pistons will work but p11 cams only nothing bigger !

I just pulled my brother sr out of is s14 ! Stock bottom end that was refresh with built head , precision 4828 and suporting mod

(Never ran after the rebuilt) Did about 6 pull on the dyno tuning the car (at around 10psi) it started to do blowby like mother fucker

We Did a leak down test and 90% leak on 1 and 4 ... 2 and 3 : 0% leak

Took everything appart to find out the ring land on 1 and 4 is cracked (stock pistons have there limit i guess or its just bad luck)

Lucky us , no damage to the cylinder walls

[RedSled]

can you use an s14/15 block without plugging the vtc oil supply on top of the block ?
i've searched and found out that a couple guys using an s13sr20det head didnt plug it cause there is only a pressure of 10psi to 15psi coming out from that oil supply due to there being a restricter and once you mate your head onto the block with your headgasket ,it seals it completely ,what are your thoughts on that ?

[rbs14kouki]

I didnt took a chance on my set-up ! Plug the vtc up front with a 1/4npt fitting it i remember right and the drain in the back with the mazworx plug that was in my conversion kit !

I did it to have a peace of mind !? Why not do it the head is of anyway .



And If you run a s14 blck you will need to drill and tap a hole to bolt the oil pump ! There is only one missing top left of the pump right over the water pump

[TEALSQUEAL]

Everyone builds because if you're willing to invest in the swap you should have the money for a built block.

[TEALSQUEAL]

Who has dyno numbers in here?

you cannot use spitfire coils on these heads, they are not long enough...,

[soundboy]

Go with ls coils and custom plug wires.

[PerilousActs]

I've seen people using 1zz-fe coils as well.

[Matej]

S15 coils are a direct fit. So are the 20V VE coils. They may actually be the same part number.

Here are others that work:

[TEALSQUEAL]

So I cleaned and cleaned and cleaned my valve cover, but I felt there was still gunk underneath the baffling...













So now I'm cleaning, resealing, and tapping/screwing down the baffling. I'll have more pictures when finished. I plan to use some pan head or flush mount screws.

[TEALSQUEAL]

30+ drill and taps later...

[rbs14kouki]

Time for a good catch can set-up to keep those fume away ! Im happy i bought a new cover now hahahahaha

[TEALSQUEAL]

I thought about a new cover, but then I figured I could put the $300+ to better use and use 2 hrs of my time and $3 in hardware. It was really easy and worth it. It definitely makes you rethink just blocking off the back outlet on the driver side though.

[Matej]

Blocking it is a bad idea. If the valve cover looked like that, the motor definitely suffered from something more severe than regular crankcase blow-by.

The valve guides were shot, so I did the supertech bronze guides and had the pentle height matched to original height when doing the valve job so I would have to do too much crazy shimming. I need to swap in some degree able cam gears so I can make up for the head and block refinish/decking. You'd be surprised how man valve covers I've opened the baffling of and it looking like that inside. Standard dinosaur is not something that is for "longevity".

[Ramonesfreak2010]

Can anyone confirm if the timing marks in the SR20DET FSM are the same as the VE head?

[jr_ss]

Match the timing marks up on the sprockets and crank gear. TDC is no longer in the correct spot using the VE oil pump with the RWD pulley though.

[Ramonesfreak2010]

Thanks. I need to buy that taarks relocation piece. I got it squared away.

[rbs14kouki]

My tuner just did a other ve last week and he's tuning one right now

Last week
Sr22vet
91mm pistons
Darton sleeve
precision 5558 ar. ? (Next turbo for mid season is a 6262)
Kelford 184-st
Fuel e-85


530whp / 430 lbs @ 24psi

No matter what pulley you use, you can just mark it directly above the slot for the key way. On any Nissan motor (at least on SR's and KA's), to get it at TDC, it does not really matter where the timing marks are, all you have to do is get the key way on the crank to point straight up vertically.

[simmode1]

Hey guys, I woke up this morning wondering: "Hmm... Does anybody make a RWD SR20VET crate motor?" Anybody know? I googled & only found the det Tomei engines.

[rbs14kouki]

Just go see Mazworx !
