As many of you know, my whipple is for sale. I've got a fellow ptnet member interested in buying it for his 03 sierra 4.8L with dbw tb. Can anyone think of any valid reason why it won't just bolt right up? I could see maybe how the wired for the tb may need to be extended, but otherwise it should fit no problem right? Whipple refuses to give me an answer since they no longer make the 2 pulley setup that I have and they never tested it on anything after 02.

I am hoping to get a solid answer either way ASAP, thanks in advance.

 

If you don't use their electronics, it shouldn't be an issue. Fitment should be identical. I bought a used 2 belt setup recently to put on my 2003 Tahoe. Haven't installed it yet, but don't forsee any problems.

 

sweet, that's what i thought. Whipple couldn't/wouldn't give me an answer. I asked the guy who's installing my new engine and he said he can't think of any logical reason's why it won't fit either.
