The Sr20/Sr22vet thread

[RalliartRsX]

So the one thing was the massive amounts of overlap of the n1 vs p12. Something like double the amount so we will see.

So far VET cams should (on paper) be the hot ticket if this is the case (low overlap) but real world testing has somewhat shown otherwise

However as yourself, I am looking for midrange and his low boost numbers would align more with what I intend to run on the VET/7163 hence why I'm going with the N1. At 20psi or so the back pressure shouldn't be more than 1.1-1.2 or so :1

In all honesty, I expect the VET cams to perform better for my 20-25psi/7163/stock unported/3 angle valve job head to perform the best for my goals.

[speedingmofa]

Awhile back people have been wondering how the stock sr20ve plenum can be flipped and welded... Well, i finally found someone who's done it:



No, it won't any beauty contests, but it seems to work and is making almost 500hp.
I thought the ports lined up like shit, but it seems to work for him!

About the cams, can someone break down what are the pros/cons (strength low/mid/top range) of each OEM cam (20ve, 16ve, N1, 20V and 20VET)?
I found this info awhile ago by Coheed, not sure if anyone's verified his claims:

"I've had good luck with the SR20VET cams. They have a strong powerband that starts to level out around 6500rpm or so, and holds pretty flat to redline. I made 440whp on 24psi with a log manifold and VET cams.

If you are running a log, don't use the stock cams. VET cams are your friend.

If you are tubular and want power under 8500rpm, look at SR20VE cams.

If you are tubular and want power up to 9500rpm or so, pick SR16VE cams.

Use N1 cams for crazy builds utilizing GT4294R+ turbos and 10,000rpm+ powerbands.

The 20V cams I would expect to fall in somewhere in the SR16VE area, and be good for top end power. But I would expect them to make a lot more mid-range than the SR16VE cams."

Anyone actually shared EBP logs on these relatively similar setups before or are we just guessing off someone's log manifold and god knows what else?

Most now have a free flowing, 3" or bigger exhaust (probably catless), .73ar or bigger turbine housing and tubular manifold. Would this still be THAT much EBP on roughly a 35R sized turbine wheel or am I just wrong too?

Go ask BW (seriously). They have a the matchbot which has a majority of this already recorded

[LuckyX2]

Matchbot calculates about 40psi of backpressure at ~8k for my SR20VE with a 7163 FYI.

Hey guys, I have multiple sets of Kelford VE cams on the shelf ready to ship, call or email and mention Zilvia and I'll knock 5% off your order!

[Will.]

Hey Guys,

I'll be travelling from Australia to the US next week for EDC LV and staying around SF & LA the first two weeks. I'm also about to start my VE build and i was wondering if it was easy to obtain VE parts from Supertech or Mazworx, how long would it take to get parts shipped over to my hotel?

It depends heavily on what you're in need of. We have a lot of stuff on the shelf but if it's time sensitive always shoot us an email to confirm availability

I regularly stock Supertech & can get you the stuff you need no problem. PM sent!

Thanks mate, i will send a PM.


I'm looking to build my P11 Head for my S15,

aimming for 370kw/500HP, responsive~ planning to run a EFR turbo. It will be a dd car and also occasional track days/time attack circuit.

Just seeing what parts would suit the build. I will also plan on building the bottom end aswell.

[livelovesole]

If you run an ATI Damper, do you still have to machine off 5mm?

sounds good looking forward to doing business with you mate!

yes you do.

My P11 head I just picked up, the previous owner ended up going RB26 on their S15, I got the head for cheap, its been acid washed and all the standard parts including cams were given to me in a separate box, Also got given a cool SR16VE rocker cover.

Going to be flying into San Fran from Sydney tomorrow morning for my holiday so it'll be delaying my build but I get to explore the USA

[RalliartRsX]

Luckily the head is very easy to put back together

However, I sure hope the prior owner properly labeled all the shims and locations......

If it's taken down that far, he'd have to go back through and redo all the shims anyway.

True. I should be more specific

I sure hope he labeled the entire valve train and corresponding location.

When I bagged and tagged the head items, a diagram was drawn up for engine location and every item was bagged and tagged and will be returning to exactly where it was removed from

[bardabe]

Hey guys am I the only one that thinks this thread belongs in the tech section by now?

[jr_ss]

It's a discussion thread, not really a tech thread. I do think it needs to be stickied though.

[Will.]

Everything's been tagged but I rather replace all them all with brand new components

I second this. This thread is getting more and more legit.

Hey guys we need someone with a VVL swap in an schassis preferably an S14 to come by and help with some product development. We have a new product that we need to test firewall clearance for.

I have one, I'm 2+hrs southwest of yous. I wouldn't be able to get the car up there during the week days, but possibly on a Sat. Pm me and maybe we can work something out.

Is anyone running aem series 2? I was curious if the units that are designed for the sr20 have any issues controlling the vvl engagement.

The 7163 come in 0.80 twin scroll T4 housing and is good for a honest 500WHP.

The manifold that I've gotten from Full-Race was the one with 2 external waste gates.

https://www.full-race.com/store/borg...urbo-manifold/

I emailed them regarding 7163 and they said it doesn't come with the external waste gate housing. Oh well

It can control VVL.

Only the Indy turbos and the 0.85 V Band B1 frame housings are EWG.

Just install a vband block off cap on the manifold and run it. This wouldn't be the most efficient use of the manifold, but it will get you on the road.

someone spilled the beans well not really, anyways, anyone used Porsche Cayenne coils. i head they pack a punch when used on KA-ts.

[speedingmofa]

I suppose Cayenne coils are same as VW coils?

Here's my VW coil pack. Fits like a glove!

Why not just use Gixxer 750/1000 coils? They are less than 50 shipped for a set off ebay and are similar to the AEM pencil coils.
