General consensus on boltons to gain the most HP.

370Z JT

About 30-35hp with a tune. JMO.


Might as well add pulley set and motor dyne manifold to maximize hp b4 getting a tune.

depends on your car. I only gained 5 hp from exhaust, longtube headers, pulley, and tune.

What exhaust do you have, Top Speed?
I gain about +17whp from the TP cbe.

cotizi

No, not at that time. I had FI Catback and FI longtube headers.

My previous Dyno was 295WHP with just stillen intakes and muffler section delete. Then when I went to dyno after installing all the other stuff I did 300WHP. (although my mid-range torque was a lot better) Intakes must have been big, because everyone seems to consistently be around 300 with full bolt-on's on Uprev's shop dynojet (where all my dynos are done).

Back on topic, I think the first thing you do, regardless of what it is will have a substantial impact. I agree with Jordo, you can get 95% of the gains of the expensive stuff and pay 50% or less if you do it right.

It really depends.. everyones cars will respond differently to certain mods.... I made +22whp with Test pipes and Exhaust...

If you want to get the most and dont ever plan on FI, this is what I would do

Stillen G3 intakes
Fast Intentions Long Tube Headers
Either FI Exhaust or HKS Exhaust
A Grounding kit
Underdrive pullies
Uprev Tune

That will give you the most without building the motor or going FI.

I guess I'm struggling with why do anything besides the single cheapest mod to gain NA power. The G3 Intake gives 17 whp.

Exhaust def gives better sound but for a few extra HP doesn't seem worth it?

Maybe FI is the way to go to get a decent bump in HP

I don't think you will get anywhere near to 17whp with any intake.
where are you getting those numbers from? you will also lose torque with the intakes. I'd rather have more torque tham HP but thats just me.

What the heck is a gronding kit and what does it do?

dad

It was voted the worst, most useless modification produced! It's crap. it's a joke. Total waste of money!

Unless your wiring is crap, not much. Just replaces factory ground wires with heavier duty ones.

Really not needed on new cars, and on older cars you'd be lucky to pick up 2 whp.

ditto, new cars have decent wiring and grounding so it doesn't do much, it basically applies for cars that strip their entire car and get a racing harness so unless you plan something crazy I doubt you'll need it

If the cbe doesn't net that much hp. How much would I be leaving on the table if I just went with Stillen gen 3 CAI and test pipes? After those mods would it be breathing enough to warrent a CBE.

One_Quick_Z

If you want the most out of your tune you will need exhaust to help the car further with "breathing" mods, easier exhaust paths/flows is better. And for people saying you dont get power out of exhaust systems is a load of BS, My Berk test pipes and HKS exhaust gained +22whp over stock.
