Yes! For all you boostfiends that love SingleSlammers, the official KA-ET Writeup!

First things first, make sure you've got time, some cash, and a good compression engine.

------------------------------------

Basic specs of our KA24E SOHC 2.4liter:

Displacement: 146 cubic inches (2.4 L)
Bore: 3.50" (89 mm)
Stroke: 3.78" (96 mm)
Compression Ratio: 8.6:1 (also 9.1 in some engines)
Compression Pressure: 142-192 psi.

Horsepower @ RPM: 134 @ 5200
Torque lb*ft @ RPM: 154 @ 3600

Camshaft lobe lift: .388" (9.86 mm)
Intake valve dia: 1.34" (34 mm)
Exhaust valve dia: 1.58" (40 mm)
Valves: 12; 8 intake, 4 exhaust

------------------------------------

Basics needed for KA-ET:

Turbo Manifold
Intercooler
Higher flowing injectors
Oil fittings and lines
Turbo
Downpipe/Turbo Elbow
Blow off valve (when upping the boost)
Higher flowing fuel Pump
Boost gauge (im an idiot and forgot)

------------------------------------
SOHC Manifolds:
Gladman performance
Import Auto Performance
JGS Precision
RealNissan.com/Nizzx.com manifold
RevHard

Intercoolers:
Any will work. Once you go higher than 370s, piggyback/standalone is a MUST!!!

Injectors should be topfeed, unless replacing/upgrading to sidemount injectors.

Oil lines and fittings:
JGS Precision

Turbo: Generally, something pretty big for 2.4L
T25 (safe but small)
GT28RS
T2871
GT3071R
GT32
T3/4 Hybrid

Downpipes and Elbows:
Everyone makes em.

Blow off valves:
JGS
HKS
Tial
Greddy

Wastegates:
Tial
JGS Precision
Turbonetics
TurboSmart

Fuel pump:
Walbro 255

MAF: 300zx or Cobra MAF *edit*(good to 500hp)*edit*
Can anyone vouch for 700hp on a Cobra MAF?

-------------------------------------

IIRC, you can achieve 300hp on stock internals, but thats pushing it. I'd personally boost up to 10-15psi on stock internals.

I forget what sparkplugs were recommended, but normally they should be regapped to .028-.03 *EDIT* Splitfire PLAT 3's or NGKs preferred *EDIT*

On stock boost, you don't need any standalone or piggyback, but once upping the boost, its a must.

Once you start boosting over 10psi, I suggest you start building internals or other support mods.

And being as our cars are SOHC KA-Es, there is a plethora of parts out in the market, albet hard to find, that would make your mouth water. Google things up. Heres a hint, REBELLO!!! And you can't forget the premier Nissan Tuner, Jim Wolf Technologies.
-------------------------------------

Dynotuning is a must. Or you could try to ghettorig that, and find an open street/lot (but thats just being STUPID!!)

Feel free to add anything, being as this is a FAQ.

My personal build would allow me to reach approx. 240hp on stock boost. But no one is interested in my tweaked build. SINGLESLAMMERS, UNITE!!!

And feel free to IM me on AIM or use the PM system if you've got additional input on this.
