Quick Question - Brian Crower Stroker Kit

bullitt5897

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??

There is it. The real question here is do you want a single turbo setup or twin turbo setup. Both have there pros and cons. As far as I am concerned, there is only one choice for each setup. All of the others that are available are suspect in my book.

If Phunk (CJM) is still selling his Greddy Twins, that would be a pretty good move as well.

I see, so sticking with the stock block would be a smarter idea if you're not really looking to fabricate. It'd be better to stick with that 3.7 block and just build from there. What do you think is a good idea for crank if I stick with the stock block?

Not sure, do you have any idea how much pounds of boost the FI Stage 3 kit will go at max? I'm pretty sure I'm not going to reach that max limit anyways, just curious. I'm looking to reach 1000hp and above, reliably.

I'm looking for 1000hp, and I'll definitely do some research on people who have previously purchased the stroker kit and I'll see what they've come out with.

Considering these two have spent close to a new house buying turbos, motors, and whatever upgrades I would take their two cents. Do some researching on guys who have built some crazy Z with stroker kits. You definitely have the funds are great, and once you get that beast up and running you will want more power. Like Cosmo said how much money you have to spend will determine how much power you will make.

All this talk of big power, makes me horny.

The OP can always do a staged build and spend the "house" over the course of a couple years. The key is engineering the build and choosing parts that allow for growth.

But hey, go all the way if funds are plentiful!

OP the stock crank will be fine for under 1000hp and daily driving. Since many here are already doing that. The link I posted earlier can make you a billet crank which is what I am running but specs for the stock 3.7L. That's the route I would go.

As for your question on the fast intentions stage 3 kit. You should expect about 1100whp out of it. There is only one person with the kit "carbon Z" and his car won't be running until after zdayz. I have talked with fast intentions at length on their turbo choice for the stage 3 and the stage 4 in my case and I am fairly confident that carbon Z will make 1100whp. Whether that's with over 30psi or mid 20's is yet to be seen. And because there are no public turbo maps for these turbos I couldn't tell you where the efficiency ranges are and where you theoretically be able to make that power.

A closed deck 3.7 with a FI stage 2 will make 1000bhp no problem!!!! A stage 3 will make it in whp and a stage 4 will make it on pump gas with ease.

I see what you mean, I've viewed CarbonZ's 1000 hp build thread but haven't checked back in awhile. I'll keep updated on his thread to see how his build turns out. Since he's the only one with the FI Stage 3 kit, hopefully he'll make a review on it. But, seeing as many people are very happy with the FI Stage 2, it obviously proves FI is reliable, so I don't see why Stage 3 would be any worse, if not better.

So I should plan to build off of my stock 3.7 block, and scratch the stroker kit idea? With a built 3.7 engine and the FI Stage 3 kit, I should be able to reach 1000 hp safely?
Also, do you know anyone whose got the 370Z R-LINE TWIN PUMP FUEL SYSTEM from AAM? It seems like it'll do well, but I don't know how reliable it is.
Of course I might just go with CJM for my fuel.


Thanks for the help

A built 3.7L motor will get you to 1000hp without a problem. However, its to be noted that quality components and a good engine builder can make or break your car and its reliability. For internals I would look into Arias, CP, Mahle, and Carillo. These are the top manufacturers that everyoe with a reliable build is running. A few have chosen K1 rods which are a medium grade budget rod. Its a great rod for those in the 600-700hp range but for 1000hp I would go carillo or Mahle. Arias and CP make great pistons for the Z and have proven to be extremely tough.

Just remember when you go stage 3 with FI they customize your turbos to your motor size to ensure you get the best efficiency and response from the kit. I have had long conversations with Tony (the owner) of Fast Intentions and their mentality to Turbo kits is SPOT ON!

As far as fuel system there are multiple options AAM is one option. However CJM is another option. You will want to go to a twin pump and ID1300's as a minimum.

Remember when you mod this far you have to have the expectation that more service is going to be needed. The reason I say this is because your taking a car making 330bhp and now pushing 350+% more power through the chassis and drivetrain. If your wanting to stage the build I would get a built motor with mild headwork (upgraded valves and retainers plus a port job) in stock displacement and compression and run that until your ready to throw the TT kit and fuel system in at one time.

Staging the install is going to cost your more in the long run if you are using a shop to do the labor. its best to do it all in 1 shot and I would splurge and get ecutek!

So it would be a good idea to use these for my build?

Carillo Rods: https://www.z1motorsports.com/engine...hr-p-8883.html

CP Pistons: Can't find the link (link it..?)

FI Stage III: FI 370Z Twin Turbo System, Fast Intentions

AAM Comp Twin Fuel Pump: AAM Competition - Nissan GT-R, 370Z Turbo Performance Specialists (with ID2000 & AAM Fuel Line Kit)

I have other questions for parts that I'd like to have your suggestion on.

Exhaust? I'm thinking of going with the AAM COMPETITION 370Z R-LINE 3" TRUE DUAL EXHAUST, which sounds great! Not sure how reliable though. I was thinking of going with the FI TT TDX, but after watching the video decided against it, not loud enough for me. Also going to go with the AAM 2.5" Test Pipes, but what do you suggest?

Spark plugs..?

No point in going on, I'm basically asking for your opinion on the ENTIRE build for a reliable 1000hp+ 370z.

Thanks for the input man!

Chuck33079

For the fuel system, pm phunk and get his thoughts. He's pretty much a one-stop shop for all your fuel needs.

Keep in mind the closed deck block has yet to be tested to it's limitations and reliabilities.. I would highly suggest going with what has been tested and true by people who are not trying endorse others products here on the forum.. You do not need a stroker kit or a closed deck block to reach your hp goals . Just trying to save you time and money but to each his own. Also keep in mind with those power levels you would never to be able to put that power to the ground unless you make a blown race car out of the z.
