There are 4 engine mods I want to do:

Air Intake kit
Headers
PCM
Cat Back exhaust

I've been looking real hard at Banks Headers lately. Air intakes by afe or True Flow, PCM by westers or nelsons, and Catback by magnaflow, borla, or gibson.(Corsa doesn't make for the 1500HD's yet).

All comments/advices are welcome

peace out

 

How much money we talkin?

 

What motor are you running?If it's a 6.0 ASM headers are hard to beat,UPD air intake are good,any of the catback systems you mentioned are good and Nelson does some really good tuning with follow up to make sure things are right.

 

get those mods and then a tune from nelson.

 

hey,

just wonderin why you picked those mods to do. are you lookin for the cheapest way to get hp per dollar? or what are your plans? was curious, b/c i can think of some better ideas than headers,catback,intake, tune. that'll ring you up some cash if your tryin to go cheap. tune is good, but i'd work around the others.

my opinion

 

I'm not going to say exactly how much, but enough to cover things.

My setup is 2003 1500HD 4x4, 6.0L, AAM950 Rear w/G80, AAM 925 Front, NVG 246 Transfer Case, 4L80E Tranny.

I picked those things because:

Phase1
PCM: from what I understand one of the best bangs for the buck
Cat Back: I wanna hear the rumble
Intake: Why not, easy 5hp.
Headers: Eventually they'll be needed

OK. I'm planning on doing a baseline dyno run completely stock next week.

Then with each mod (or maybe two at a time) another run to record results.

I also have the G-Tech Pro with some baseline 0-60 runs I will be using as well.

Phase2

Tranny shift kit: Trans-go
Torque Converter: Yank 2600HD

Then another dyno/0-60 runs.

So thats the plan, just need opinions and advice.

The other thing is I'm not sure if I want to go s/c or not yet. I think I would like to try Normally Aspirated first. Plus I'm still under warranty.
maybe that will help a little more.

Are the ASM headers CARB certified (CA truck)

peace

 

did i say something wrong?

where's all my advices come on guys, I'm in need of some experienced words of wisdom.

 

ASMs aren't CARB certified,FLPs are but cost more,but include high flow cats and custom wye-pipes,don't waste your money on shorties the long tubes make about 15 more horsepower than the best shorties.

 

thanks whitt1, do you have a link for flp's?

 

If FLPs are not carb legal. At least not in Cali. Any long tube is illegal as it moves the original posistion of the cats which is a federal crime

Good news is headers are easy to remove and reinstall the stock stuff come smog time so I wouldn't worry about it.
