I would think that anything that is CARB legal is ok, but I'm not from Cali. I'm moving this to the auto tech section, it's better off over there. |

Each one gives you 10 horsepower! This is a good place to start. https://idforums.net/index.php?showtopic=37238 All jokes aside... From what I understand in California the CAI needs to have a CARB number. |

I always start with rims myself. I think it's an obsession. | ||

rims are good too but Los Angeles roads are way to unforgiving for low profiled rims =X pot holes and dips nearly everywhere. my sis cracked her 18 inch rims on a dingy pot hole so she sold it and got steelies to drive around in. | ||

Ricer. Anything CARB legal will pass, provided everything else is within the requirements for the year your car was made, e.g. carbon emissions, lack of CELs, etc. Z31, turbo or NA? | ||

IDW Saiyan Group: Advanced Members Posts: 9,139 Member No.: 1,205 Joined: Jan 31st 2004 Location: Dallas, Texas | First you probably want to allow your engine to breathe. Then continue with a cat-back exhaust. What are your goals? Depending on your transmission, you can determine what parts to get next. Automatic and manual cars make the same power at the engine, however manuals transmissions put more of that power to the ground (12-15% M/T drivetrain loss verses ~18-20% A/T). Therefore, modifications like light-weight flywheels and driveshafts will increase the rear wheel horsepower without actually increasing the power at the crank. |

Ah, how immature. Understand that I didn't see that he had a Z31. | ||

Plenty of drivers seem to drive around Los Angels with huge wheels, and no problems. Sounds like your sister just sucks at driving. | ||

It's a joke. Pretty much every ricer you talk to, and ask what they've got done, that's their answer. Intake and exhaust are good, "headers" or manifolds as they're technically called, generally don't need any work beyond porting unless they're incredibly constrictive. I'll be running my 300awhp build (400bhp) on stock, unported manifolds. Eventually I'll upgrade (SMIM, TEM) for more torque, but as it stands there's no need. | ||

Ah sorry, I'm not really in a joking mood right now. But headers really do make a difference. But if he has a Turbo Z31, I don't see the point of upgrading the Exhaust Manifolds. He could get an aftermarket Downpipe, or even lightweight wheels. | ||

That's a good way of observing it, and one that I would be inclined to agree with. That made my day, basically. It's one quote that I shall remember. | ||

Depends on the design as far as I know. Generally, factory exhaust manifolds are a big collector attached to each cylinder with a single pipe coming off it to the exhaust. Upgrading the headers to something that collects from each cylinder individually makes quite a difference. In the case of my blacktop 4A-GE there's not much to be gained beyond replacing the factory 2-1 section, as it's pretty restrictive, yeah, but on my old S13 it would've been a bit of a difference to replace the factory manifold. | ||

Agreed, it really depends on what your car came with stock. Some of them are no more than a glorified collector that's shaped like a box, with pipes sticking out at each cylinder. >_< | ||

Srsly I'm the Stig? Group: Advanced Members Posts: 1,116 Member No.: 11,448 Joined: Aug 24th 2005 Location: SoCal 310 | Just as a question, why do you want to have a faster car? It seems that you only want to reap the benefits of having a "faster car" but don't want the cons? No matter what, if you have an aftermarket exhaust cops will hassle you. Whether or not they are legal it doesn't really matter because they will make YOU prove that it is legal instead of having them prove it is illegal. |

Exactly what I wanted to say. Perhaps a better way to make your car faster is to learn to drive it better. Once you have the driving half taken care of, work on mechanical adjustments. | ||
