I am helping a friend replace his fast 78 with a fast 90 intake & nick williams TB. My question, How do you hook it up to the MAF & lid? Will the stock bellows fit? And what about the air lid. It is going on an LS2 402.

I doubt that you'll be able to make the stock bellow fit around the 90mm throttle body. I have the new style SLP bellow on my car and was barely able to make it fit my Nick Williams 90 TB. You'll need about a 3" ID silicone coupler, hump hose, etc. if I remember correctly. Might want to stick a tape measure on it to be sure. The stock MAF and any lid will work fine, you'll just need some stainless steel ring clamps to tighten the silicone coupler around the MAF good. I'm still running the stock MAF and an SLP lid with my 90/90. Don't know of any sponsors that sell silicone hose or I'd recommend them, here is a place that sells it though:

Thanks. I think the local speed shop may have something like that.

I just want to make sure it goes smooth. I get his FAST 78 after we are done.

The throttle body is only .050 bigger than stock where the bellows goes on. I have never had a problem getting the stock one to fit. It is a little tighter though.
