It's almost like trying to get a hold of that Bryan guy which used to work for GST.



In all seriousness, I wish I would have waited to turn up the power in my car until after I had reached the limit of it in stock form.

 

I remember something about the stock rear diff bushings causing this and fixable by replacing with aftermarket ones

 

Booming/ Banging noise is when shifting fast from gear to gear--the boom is coming from the diff as stated above. I thought this was solved by clutch stop, correct?

 

You're talking about the mustache bar clunking when shifting under load.

You can stop that noise with a mustache bar eliminator:



or by upgrading the OEM rear diff and mustache bar bushings with polyurethane.

 

This.

 

even if i shift normal and yet i dont mix gas and clutch very well i can hear this boom/bang/thud noise.. i hope this isn't related to any mechanical that'll cause me $$$.. sorry guys for going out of topic, im just bothered by this as i just got this car for like 2 weeks ago and haven't really drove it everyday. thanks for the replies though!

 

Bingo. this is what I meant.

 

Biggest regrets to date on my '03 are:

1. Going with a GT3071R turbo as my initial turbo upgrade
2. Going with a XEDE piggyback instead of just biting the bullet and going straight to standalone.

Regret not saving my money for a greddy ti !!!!!

 

I hate mine as well, but it came with the car. When I got the car the allen bolts were stripped, so it made it that much harder to take it apart

The previous owner also bought a greddy uicp for the car, and it is terrible. its too big, rubs against both the battery and radiator hose. Plus I have blown the pipe off twice, and it took me almost an hour to finally get all the couplers to quit leaking during a boost leak test w/ new clamps.

 

Seriously.

I love my build but I regret not having a tuner to take it to the next level....

 

If your getting a clunk from your rear diff, upgrade the mounts. If you upgrade, or use the mustache bar eliminator, could be a u joint in the drive shaft.

 

So is this clunk/bang noise pretty common and natural with these cars? Sorry for asking guys as im new to evo world..

 

i regret getting FORGE bov. should have stuck with my stock IX. too much flutter at half throttle

 

The ACT 6 puck unsprung clutch. Absolutely horrible in traffic, but i must say I'm used to it lol
