What are you go pushing with the twin scroll GTX3076 turbo? I want at least around 550ish HP. This is the only turbo i have laying around besides a greddy 18g. I want to see who's doing well with the twin scroll GTX3076 and what numbers are you guys putting up so i can determine on cam setup.

P11 cams are good for 600 HP. I would not spend the time on cam choice unless going for 6-700 WHP (not Crank HP)

[s13silvia123]

honestly I want 600hp.

P11 VS. P12 cams. which one would be more sufficient in less lag and quicker spool.

[RalliartRsX]

P12 are supposedly better.

However, if you want 600 HP either P11 or P12 will work or go spend $1000 on a set of Kelfords (which are out of stock until Nov direct from Kelford, although Mazworx should be getting new shipment shortly)

[speedingmofa]

Why is there no love for 16ve cams? My head came with them so I'll be using them on my build....

[RalliartRsX]

EDIT: I will dig some of the info up on the ramps and such on the 16VE cams

In the meantime, this is a VERY good read! Lots of head and cam info (including info on ramp angles for the VE and why you can use the 16VE cam and not float stock SR20VE valve springs past 8000 RPM)

Awesome, thanks for the info! gonna read this on break.

[RalliartRsX]

One thing to take a note of: What works great for a NA VE, does necessarily translate to a mild turbo VE (example: relatively long duration cams).

Mazworx already has them, I got my 184-St's on Tuesday. Call Hanz, super cool dude to work with.

The problem with P11 cams is they fall off hard up top.

P12's are an upgrade over the P11's but the N1's are the bees knees in terms of factory cam options. There is no sense in spending $8-900 dollars for $400 cams with Kelfords(184-B) name on them.

I'm not saying there aren't better options, but for most people in the 4-700hp world, 1k$ cams aren't needed.

[RalliartRsX]

Kelford has several different cam options through Mazworx. It seems they were using the 20V low lobes and the N1 high lobes and 20V overlap (or something like that).

I wouldnt spend 1000 on those, but if I were to spend that kind of dough on cams, those are the specs I would shoot for if I want 600+ WHP.

The N1s are great on high boost.

Isn't that the only type of boost? ;p

When people ask how much boost I am running. The response

ALL OF IT!

[hanzbrady]

Hey guys just to chime into the conversation, we are now dealing Kelfords directly as the US distributor that they were working with no longer plans to stock them. This means that we now can get cams usually in about 2 weeks if we don't have them on the shelf. We try to keep quite a few in stock though so if you're interested shoot us an email or give me a call!

Hey man,

My name is Hanz (kinda like from Frozen & Star Wars (Yes I know that technically Han, but this helps people haha.) .) We actually just closed but shoot me an email [email protected] and I'll answer your questions 24/7 for the most part.

[TheRealSy90]

Hanz is the best.

I've commited to going the vvl route for my sr20. I've been doing my research on alot of build threads and online sources and believe i've come up with a decent 450-550hp build. I do have a couple questions if anyone can clear them up for me. Any recommendations/ tips/ advice and any positive or negative feedback is greatly appreciated.

S14 Block:
Necessary machine work (deck, hone&bore, hot tank, balance rotating assembly, etc)
CP SR20VE Pistons 87mm 9.0:0 comp. w/ gas ports
Manley H-Beam connecting rods
SR20VE Headgasket
OEM S14 water pump
Oversized water pulley
Plug off unecessary holes on block
Mazworxs timing mark relocation kit
Tomei oversized oil pan
Tomei oil filter relocation kit
ACL wpc treated bearings
ARP main & head studs

P12 Head:
Hot tank and deck
Mazworx comversion kit
Port & polish
Cnc combustion chamber machining to 87mm
Q45 Throttle body
Denso IKH24 spark plugs

Turbo:
Full race top mount SR20VE exhaust manifold w/ dual wastegates
Custom 3in elbow and downpipe

Fuel:
Mazworx fuel rail (in kit)
All AN lines
255 walbro intake to bosch 044 external fuel pump
Surge tank setup
ID1000 fuel injectors

I'm deciding between AEM pencil coils or IGN A1 coils but undecisive ao far. Any pros or cons
Between the 2?

Do you use the OEM SR20DET Timing Chain Kit with this setup?

Very undecisive on a turbo, any personal recommendations ?

I don't want to select a standalone until I find out what my tuner will recommend and is most comfortable with, but any recommendations on this as well or personal favorites with good amounts of failsafes ?

Are any of the S13 guys running into any issuses with hood clearances? I have a dmax vented hood and curious if it'll clear or am i going to have to shave some off.

[jr_ss]

I'd get 1300cc or larger injectors. You'll max the 1000's out on E85 around mid 500's. Sr20det timing equip will work fine. Make sure you have the proper spacer for the crank pulley.

A twin scroll setup would be the way to go if starting from scratch. If you have a single scroll manifold already, look at the EFR series turbos. The GTX turbos are good as well, if you are sticking around the 500whp mark. Some complain about the response of the 3076R, but this is a great turbo for strong mid range and top end. You'll suffer some spool over an EFR of similar size though. A GTX3576R spools like a 3076r but flows like a 35R.

I recommend a Haltech unit. Designed around Factory Nissan sensors, which means less sensors needed for install. There is also no need for CAS modifications or additional trigger wheels or sensors, you get full 360* of resolution.

I think you have quite a few unnecessary things. Port and polish and combustion chamber machining are not needed, especially with your power goals. I have a stock head, upgraded valve springs and make 485whp on 19-20psi.

JE DET pistons in the 8.5:1 ratio will net you higher static comp than the VE pistons. They are also cheaper.

Thank you alot for the information. I do plan on running a twin scroll setup, sorry for not metioning earlier and I'll deffitnitly look into/ consider the gtx35. First time building something to this caliber, want to be safe. Do you think springs are necessary on a P12 head for my power goals? Assuming their supertech det springs that you use.

[Options13]

has anyone had the denso pencil coils from mazworx fail on them? my car has randomly started misfiring but the mis fire goes away instatly once the car hits about 3k rpms..

my TPS is cracked and MAY not be functioning, but i don't think that could cause this mis fire?

[candyred_240sx]

Had my sr22vet on the dyno today.

667whp/555tq dynojet

GTX3076r .78 twin scroll @ 30psi running 70% ethanol

Pretty happy with the results, car ran 10.7 1/4 mile on Friday hopefully can get it down to 10.4 or so at this power

Thanks for the info. I follow your build closely on your thread. Will most likely be my setup as well. Just secured a P11 head as my first baby step.

[1gr8bar10der]

Also just out of my curiosity, with these 500++HP numbers, what clutch do you guys use?

[600supersport]

With torque being the issue for the clutch, I opted for the Comp twin disc and it's great on track, but I'd seriously consider the spec stage 5+ next time for the likelihood of a much smoother and more streetable feel with a significant torque capacity, but I haven't tried one yet and I don't street or track the car THAT often. It'd be nice if the car was a bit gentler on the stop & go stuff. I guess I'd expect that single to have a higher chance of overheating after some hot laps than the twin would, but that's pure speculation and I'm not out slipping the clutch a lot or kicking it like crazy either so it's a tough call.

Stiff coilovers, stiff mounts and a twin disc clutch are more physically demanding on me after cruising around for a bit, but they're amazing once you're out on track.

Nice job btw candyred. What transmission and cams are you using?

Thanks. N1 cams and z32 transmission. Kelford cams are on order though

Mazworxs timing mark relocation kit i prefer the Taarks one
Tomei oversized oil pan phase2 pan is pretty much identical,
i went to FRsport and had a phase2, a tomei, and circuit sports pan all right in front of me, and all 3 of them look like comparable quality. i have had a few people tell me that their tomei pans, the flange is not totally flat and they're had to either deck it or use additional silicone to seal.
Tomei oil filter relocation kit
ACL wpc treated bearings WPC is the shit. hit up Bluemoon / MKS in costa mesa if you need WPC service or engine building. they're partners with WPC
ARP main & head studs

P12 Head:
Hot tank and deck
Mazworx comversion kit again i prefer taarks, especially since their latest revision doesn't have a bunch of lines moving the solenoid elsewhere
Port & polish
Cnc combustion chamber machining to 87mm i agree this is overkill for your power goals
Q45 Throttle body what manifold are you planning on? xcessive is nice and very budget friendly, PRL is VERY nice but more ($800 range)
Denso IKH24 spark plugs

Turbo:
Full race top mount SR20VE exhaust manifold w/ dual wastegates
Custom 3in elbow and downpipe

Fuel:
Mazworx fuel rail (in kit)
All AN lines
255 walbro intake to bosch 044 external fuel pump
Surge tank setup
ID1000 fuel injectors maybe i missed it but are you running pump gas or e85 or race gas only?

thats excellent. i'd love to see a dyno run! is your engine just sleeved and bored out or stroked also?

What CAS and disk are you running and what are you doing for engine management?

[Options13]

I'm running aem ver 2 with aems trigger wheel

I just installed used CBR Denso coils into my motor. Haven't really run it too much yet but my spark issues(misfire on AEM pencil coils) are gone. Gapped at .028 pulls hard to rev line at 20psi no blow out.
