Hope this is in the right section . If not feel free to delete.
So I just bought a 03 silverado scsb .
It has a ls6 swap with cam,243 worked heads and a ported 6.0 intake.

So my question.
I want to change the intake. I have a cowl hood so I'm thinking I can fit the Holley high rise, I seen edelbrock has one and a lsx rt I believe.

What would be the best buy? Any others I should look in to ?
Feel free to post links
Any info would help thanks

 

Are u planning on going forced induction or nitrous? U may want to read up on the fast intakes if your staying n/a.

-nate

 

It'll be n/a for a while then 100-125 shot . What's the pros and cons for the intakes vs n/a or nitrous

 

I guess what I'm looking for is what's the best for n/a application ?
Mainly bc I'll be driving it like that most of time .
Yes in the near future I'll have nitrous but that will only be used here and there lol

 

TBSS/NNBS intake, cheap, makes power over the stock truck one.. I would not run that over priced plastic LSXRT intake.. If your set on a aluminum one I would go holley Hi ram or the edy, but they are costly.

 

If you go with nitrous run the Vic jr and just run a cheap 4150 nitrous plate.

 

Don't let the people on here discourage your decision about the Fast LSXRT. Some guys on here had bad experiences with it, but many many many more people in the world have had excellent experience with it.

It will require a tune, and probably several idle adjusments after the fact, to get it perfect, but if its done right, you should see significant gains.

I however, don't think spending $2000+ is worth the gain.

Good luck

 

The truck makes decent power for what is
415 rwhp
Honestly some of it's for looks but I'm always looking for more power.
I read a article were the edelbrock made 39 more hp then the 6.0 intake on engine Dyno.

Tunning won't be a issue. I live about 5 mins from my tunners shop

 

look into the fast 92 and 102 intakes. my brother is about to get a 102 for his ls1 with similar mods and is expecting 35+ horsepower from it and tuned

 

Looks wise, money no big deal, the holley gets my vote, it makes power
