Howdy y’all, last May I sold my first G, it was a salvage title G37s that was actually pretty clean for what it was lol. I bought it myself(16) and was very proud... got a ticket and didn’t want to pay insurance, two months ago bought a 08 V36 g35 sedan with a 6speed!
Ive always been very entertained by just about anything with a motor, I’ve built go karts and used to work on snowmobiled with my pops.
I’ve dream’t of building the motor of my car but always been to scared of the money factor and the fact that I’m very young...
Yesterday I bought a bare block and I’m gonna start building it but I need help. So far I have the shop I’m going to get the block squared up and honed at. Next I need help finding forged internals. I DO NOT WANT TO STROKE IT. I believe I want stock compression(11:1?). I only bought bare block so what are some good options for forged pistons, rods, crank etc. trying to write up a build plan so I can make a timeline.
100% chance I made some mistake in this post so feel free to roast me I have thick skin

 

Just to verify, you're going turbo, supercharger, or nitrous on the build correct? If not then there's no reason to upgrade to aftermarket internals really since the rods can handle 450 and the crank can handle almost 1000.

Might as well get a crankshaft for the VQ37VHR and use it on your VQ35HR motor. It's basically a drop in and will net you slightly more displacement. Should be plenty of info to google, I know it was a pretty common mod. I think it can be used with VQ37VHR rods and different pistons but not totally sure, never done it personally. Again though, should be able to google all that info.

 

I am planning on single turbo, however the motor will
be complete and in my car for a while before that due to money. I’m 18 and about to be in college. If the Stock crank can hold that much power then I will just buy a stock one.
To clarify I am building bottom end to hold 600-700whp after turbo, but I will be swapping it into my car before installing turbo. I’m doing this because the motor in my car has 160k on it and because I won’t have money to turbo for a little while after the motor is built, the motor I have runs perfectly and doesn’t leak a drop but I would like to have a fully rebuilt motor with bolt-ons until I turbo. I want reliability.

 

The decision is going to be whether to throw in low compression pistons now and drive it N/A with substantially reduced power or to throw in high compression pistons and just run less boost when you eventually turbo it.

Personally I would just keep the motor out and build it for the turbo and NOT install it until you're ready to do the whole upgrade, or just build it N/A and take the EXISTING motor and build it for the future turbo setup.

Make sure you replace the galley gaskets with aftermarket ones so you don't have a blowout and P0011, P0021 codes.

Either way with an aftermarket forced induction motor it's a good idea to have a spare engine built and ready to drop in when things eventually kaboom or hit 100k miles, whichever comes first.

EDIT: Stock compression is 10.6:1 and typically you use 8.8:1 for turbo which will mean you lose about 8-10% power if N/A. That's going to equate about a minus 25-30 HORSEPOWER but your torque loss will be even greater, probably in the minus 35-40 torque is my guess.

 

So my question is, can I keep stock compression and then have normal power and then also make good numbers on stock compression?
thank you very much for all the help and information

 

Yeah you just won't be able to add as much boost, you'll still be in the 450whp or so mark on stock compression pistons with a fully built engine.

Read the edit I did on post 4.

Something else you should look into since stock components are cheaper, use the VQ37VHR intake manifold on your VQ35HR.
