Quick Question - Brian Crower Stroker Kit

WhatnowGamer

BrianCrower.com

On this stroker kit, how much pounds of boost will I be able to hold up?
I'm looking to build internals on top of this stroker kit, so what type of horsepower do you think it'll run with a built engine on this stroker kit?
What turbo kit will work well with this stroker kit?

Thanks for the help

What are your power goals and do you plan on putting that power down to the ground or just want high dyno numbers. Most any turbo kit these days can get you where you want to be.

Also, this stroker kit will already be forged. So this kit will make your bottom end "built".

Like Cosmo said, you can't go wrong with the turbo kits available. The main 3 seem to be Boosted Performance, AAM, and Fast Intentions. Fast Intentions is def a forum favorite. All 3 of those will get you to your goals with the right planning (turbo sizes and appropriate fuel upgrades).

I have the stroker kit FS if you're interested. With low compression for boosted applications.

No certain power goals, I'm looking to see the max power I can get. Definitely planning on putting that power to the ground though.


I see, I was thinking of buying the FI TT kit, but I'm wondering with the combination of the stroker kit and the FI TT kit, how much pounds of boost will I be able to hold up?

I'm also planning on purchasing

Air: AAM COMPETITION 370Z R-LINE 3" TRUE DUAL EXHAUST, AAM COMPETITION 370Z 2.5" RESONATED TEST PIPES, Nissan 370Z 409 Stainless Steel Headers - Ceramic Coated, FI TT Kit

Fuel: 370Z DRAG RACE R-LINE TWIN PUMP FUEL SYSTEM, AAM COMPETITION 370Z FUEL RAIL AND LINE KIT, INJECTOR DYNAMICS ID2000 INJECTORS

Oil: AAM COMPETITION 370Z R-LINE OIL COOLING SYSTEM, MISHIMOTOR 370Z 66 DEGREE RACING THERMOSTAT AND HOUSING, Mishimoto Radiator

Also planning on purchasing other performance parts such as headgasket, ECU, clutch, differential, studs, etc..

I'll also be getting necessary parts to go along with the power such as brakes, sway bars, coils, racing seats & harnesses, etc..

So, with a FULLY built engine and all other necessary requirements, how much boost do you all suggest I'll be able to hold up?

How much boost is a function of turbo choice. 10psi out of a huge turbo is a lot more air than 10 psi out of a small one, so you can't just ask "how much boost".

Also, FI has a 3" exhaust and oil cooler and your fuel system should come from CJM. Ditch the AAM and mishimoto stuff. You don't run headers with a turbo.

I second this recommendation...


(your fuel system should come from CJM)

Plus you won't need test pipes when Fast Intentions provide different options of downpipes for their turbo applications.

I would shy away from ordering a BC stroker... I have heard horror stories...

That and I have held the OEM, BC and Mine all side by side. The OEM and Mine were much better quality.

Mine is a private label crank for GTM but here is the manufacturer:
Billet Crankshafts | Crankshaft Repair - We Fix Crankshafts - Marine Crankshaft, Inc. - Outboard Crankshaft Repair

Being as I have span the gamut of power levels for this platform... I have had my hands on a 600whp car all the way up to my current 1000whp car soon to be alot more. I will give you some sound advice that will spare your wallet.

The 3.7L is more than capable of making 1000whp. I would get a closed deck block go with a stage 2 Fast intentions kit with all the options. I would look to CJM for your fuel needs or if your a ways out Fore innovations may have a solution for us at a GOOD price. Each manufacturer of their turbo kits has an ideal setup and after talking with multiple manufacturers my money is on Tony and Team @ FI. Their kit has the best design to date for mid mount twins and is more than enough to get you to any power goal you want. ohhh and as far as clutches go stick to OS giken double for anything under a 1000whp you wont regret it.

Remember speed costs money... how fast can you afford to go?

My first round cost me greatly! my second round is going to cost me nearly $20k just switching kits and gettign upgrades for parts I expected to break.

And his shiat afterwards better put out or he's going to catch A lot of Hell from me... lol But as much as I hate to admit it he's right about the price point. How deep in those pockets are you willing go? Remember in the 350z days 400-500whp used to be the **** but now the bar is constantly being pushed higher and higher..

WhatnowGamer

Yeah, I don't have any idea about the reliability of certain parts, but I am looking to do the best and most reliable build possible at the same time. Any help would be appreciated

If your set on going stroker I would go closed deck and a 4.0L stroker. As far as internals go look to cp or arias Pistons, k1 as budget rods or Carrillo pro h rods as the go to bulletproof rods. I would also port the heads and upgrade the valves and retainers in your heads. If you want to go up in size on the valves that's fine but no more than 1mm. That should cover the general items.

Again I would start with figuring out what kind of power you want because chances are you won't even need a stroker kit. Build a motor (and it doesn't have to be a closed deck block unless your planning on going over 1000whp but the no one knows what the limitations are on this new block either) and go BP or Fast Intentions. 600whp is more than enough hp for the street unless you want a dyno queen and have your car down all of the time..

The benefit of the stroker kit is your low end torque. Not only that but with the normal size turbos (meant for the 3.7L) you will be flowing more cfm than the 3.7L which means the turbos should spool faster but with the negative effect of a lower top end. This is all dependent on the turbos you pick and the size stroker you go with. A big advantage of not going bigger than 4.0L is that you get to have stock bore size. One of the downsides of the 4.5L is the larger rotating mass which requires a special cometic head gasket. A plus side is the car has a lot more torque and acts more like a hi revving v8.

Keep in mind traction in a boosted z the first 2 gears are pretty much a waste because all you would do is spin the tires from the power. Based on that FACT save your money on buying a stroker kit kit because you don't need anymore tq down low. Again where do you want to be in power and how big is your wallet??
