What's the best way to achieve 50hp?

FI or nitrous. Bolt-ons alone aren't quite going to get you there.

Oh sure they will. Pistons, Cams, heads, headers, intake, exhaust and tune will get you there with hp to spare. It's all matter of how much you want to spend. Forced induction isn't the only way to get over 400 hp. You don't need nitrous or forced induction.

I always find these discussions funny. Much of the discussion is focused on peak HP with a few people who get it. What is primary use of the car?

If it's a street car you should be more concerned about maximizing mid range torque and hp over stock baseline. Too many people focus on peak number due to lack of understanding what makes a fast car for each application. If you can't make a redline shift every time 50 peak hp at top of rev limit isn't going to help if you lose critical mid range power.

Having said that a proven good set of intakes that don't hurt torque numbers, long tube headers, Uprev tune should get you 20 to 25 hp/ torque that is usable from mid range to top end. The stated hP claims for all bolt ons are wildly exaggerated and tend to be focused on peak hp. Most use a poor stock dyno run and then put up a good run with bolt on to make hp claims. many don't tell you type of dyno or if it's a properly corrected number. Dyno claims are like weight loss pill commercial claims in my opinion. Lots of wild claims with few facts or data often.

Realistically only way you're going to gain 50 usable hp in a street car is to go forced induction. A few bolt ons will not likely get anywhere close to more 50 HP on a Nismo.

I'd love to see someone do a large displacement motor build. I think bigger displacement VQ would grab 50 plus hp easily. Something like 4.5 liter, aggressive cams and heads, etc but that goes beyond simple bolt on.

With my nismo I have focused more on getting weight off the car especially rotating weight. Aluminum hat rotors, lightweight flywheel, and lightweight 18 inch wheels are best bolt ons in my opinion.

Those aren't considered "bolt ons." The only other all motor VQ I know about that's close to 400 is the Nismo 380RS which is 380ps. True, forced induction isn't the only way to get over 400 but it's certainly the most cost effective. The problem with trying to go at or over 400 with the VQ37HR is the lack of research, development, and parts for all motor builds.

Internals on an FI motor are no more prone to wear than internals on an FI engine laying similar numbers down.

I'd love to see pics/dynos for your build



pistons are not bolt ons

Besides, most of it is about getting usable power, not just power above 5 grand.
