Upgrades?????

[HBH3]

I have 35's (yes 315's) on stock weheels. They only rub a tad against the sways bar on full lock on right turn, not left. That is easily fixable by welsding a small piece of metal on the turn stop.

I also have done the PCM for less and it made a noticeable difference; and I have a 5 spd not auto. They also do correct the speedo for larger tires so the mileage and speed are accurate.

As far as leveling, I did the Readylift leveling kit. The ride is the same, and it looks perfectly level.

Enjoy!

Hey guys Thanks again, So you guys are not running any aftermarket intakes? I was just on the web sites and they all say that there products will increase hp and gas milage. this was off the dyno. anyone try doing intake and exhaust and ecm? just wondering.
Thanks for the suggestions I will look at readylift and check them out.
One question for you guys, to go with aftermarket wheels what offset is suggested, I say one demension cant find it again. And if i did a different offset will this increase or decrease the rubbing.?
Thanks again.

The Spacer is really questionable on any vehicle.

Cold Air Intake ... Trace out your H-3, it already comes from the factory with cold air intake (send me your money instead)

Exhaust --- there you can gain a few extra horses...

For the money I think the re-program is the best. I have both the itake and exhaust. Between the two there is a slight inprove in both power and fuel mileage. I do like how the exhaust sounds though, so not a complete disappointment.

Depends on the width of the wheel. Stock wheels are 7.5" wide and have 5" backspace. For a 8" wide wheel, you'll probaly want 4.5" backspace. The wider you go, the more backspacing you want.

Thanks again guys, these ques may seem a little premature for me but like I said I'm trying to get all my research before I purchase this h3. Ive got my credit union selling my truck this weekend so hopefully things will work out.
So I guess the ecu/pcm4less and an exhaust r the way 2 go. Thanks 4 the 411 guys. I think I would like more hp's from the exhaust rather than the noise, so what do you recommend, i've been to volant, corsa, magnaflow, and borla. Which is the better in your opinions.??
Thanks in advance I think this forum is great, despite the posers that will invaid and try 2 put there 2 cents. keep it up guys

For HP and torque gains, go with Gibson (not on your list) or Borla. Get the full catback, not just the muffler.

And just my 2 cents, but for any so-called performance products, do not expect better gas mileage. The only way to improve the mpg is to improve combustion efficiency or reduce parasitic losses (friction, air resistance), and airflow products do neither.

Air intake and exhaust mods may allow the engine to breathe better, but that only allows the PCM to add more fuel to accommodate the extra airflow. And it only happens when you ask for it (by pushing the throttle). Since the extra power comes from the extra fuel per engine revolution, you won't see mpg gains.

I highlighted "may" because there are other problems. The question isn't, "Do intake and exhaust mods eliminate restrictions?" You should be asking ...

1.) "Is the stock intake and exhaust more restrictive than the ports and valving in the engine itself?" You won't see any gains unless the answer is yes.

2.) "Did the company engineer the airflow specifically for my vehicle, with regard to the pulse frequency of air traveling through the pipes they designed?" Timing these pulses is critical to pushing air into the intake manifold (or extracting from the exhaust manifold) at the right time.

3.) "Does the aftermarket intake seal off hot engine air?" Hot air is less dense than cold air. In a given volume (like the combustion chamber), cold air will contain more oxygen molecules than hot air. Less oxygen is detected by the MAF, which tells the PCM to send less fuel to each cylinder, resulting in less power from each combustion cycle.

A lot of aftermarked intakes and exhausts actually reduce performance because the company (or kid with the pipe cutter), didn't design the system to your engine application, with these points in mind.

very nicely put

Thanks, So Hadden are u suggesting that the only upgrade out there for this particular vehicle is the catback system? ( I would only put the catback on my vehicle, only way to go) I've read so many posts that they can c improve ments with the pcm4less upgrade. I was under the assumption that with the ecm upgrade that it would do all that, to improve shift points, mpg, and torque. You obviously know what your talking about, so is the pcm4less false with there advertisment and a waste of time?
Well if you cangive me more 411 I would appreciate it Thanks in advance.
