Looking for more top end

lpraider50 · Oct 18, 2011

Got a 97 gt 5 speed. Already have intake and exhaust. Looking for more top end. What suggestions do you guys have aside from headers and x pipe because thats already on my list to get.
Thanks!!

You only have a few choices:

First of all, definitely change the rear gear. While it doesn't add horsepower, the engine will be able to get to its power band much quicker. It makes a world of difference.

As far as actual power, most popular and pretty cost effective is swapping to 99+ intake, heads and cams. This will put you in the 270ish hp range (at the crank) due to a small bump in compression over a factory 99-04 engine.

If that doesn't interest you, next most cost effective choice is nitrous. The downside is you have to open the bottle when you want to use it, as well as refill it, make sure it stays a certain temp., etc. It IS the biggest bang for the buck, though. Assuming your engine and fuel system is in good working order, the car could handle a 100 wet shot all day long.

If that's not your cup of tea either, look at basic Vortech kits.

Step 1: install Nitrous Express 2v plate kit
Step 2: outrun supercharged cars and have $4,500 less in the set up.

Until the bottle run empty and the Supercharged car blows right past you.

Twin Screw>NOS

In all seriousness tho. If you are wanting to do it without a power adder, you will needs heads and cams.

Superchargers and turbo's are a good route because you don't have to mess with filling bottles and what not. A PD blower will make a lot of torque, and a Centri will make a lot of top end. A turbo makes both, but just not as much low end torque as a PD blower.

SRT Handz · Oct 18, 2011

Turbo's lag... Lag is kinda lame on the street.

Stumbaugh · Oct 18, 2011

It's called Nitrous, not NOS.

That's why I keep 2 bottles in my car. When 1 runs out, I switch them. By the time the 2nd runs out, that will have meant I have made over 30 passes at the track. I figure I will be done for the night at that point.

SRT Handz · Oct 18, 2011

I never really go to the track, so i want my stuff on right now. I dont really like turning on a bottle.

Yes, it is called NOZ

and when you run NOZ, you should run 3 bottles, the Big ones, just like Fast and the Furious.

Beware, danger to floor if you go over a 900 shot.

Stumbaugh · Oct 18, 2011

That's why you buy a remote bottle opener. Press a button and the bottle opens.

My floor pans are reinforced. Toretto did it for me when we installed both kits.

Did he do the custom NOZ fogger system? I heard that gave Johnny Tran the winning edge is his "Honda 2000"

Stumbaugh · Oct 18, 2011

Sure did. I have the updated version of Johnny's set up. Makes way more power.

SRT Handz · Oct 18, 2011

Damn, i think i got hustled when hector hook up my NOZ, It only sprays iced tea :-(

Stumbaugh · Oct 18, 2011

You should have had Dom do it. He would have let you help. He has all the tools you need. If you couldn't find the tool you needed in his garage, you don't belong near a car.

SRT Handz · Oct 18, 2011

He did have the MM bushing removal tool for UCA install so i had to go to Racers Edge and pick it up

Stumbaugh · Oct 18, 2011

I was using it out at Race Wars. Must have left it in the camper. My bad.

The problem with your car is the NPI heads and NPI intake manifold. When combined they run out of breath at about 4500 RPM's. You can install the PI intake manifold on the NPI heads and it will improve the top end performance, but it will still be slow. I have installed a PI intake manifold, stage 2 cams, and exhaust mods (listed below) and my car still falls on its face at about 5K RPM's. The NPI heads (in stock form) just don't move enough air to ever get a decent increase in top end horsepower.

Haha I was cracking up at the fast and the furious lines.

What's your budget is the real question?

Looking for more top end
