Whats the throttle body coupler size? 3"? i'm now waiting on parts to do the ls1 lid conversion i bought the standard ls1 lower air box with filter frame & i have a aftermarket RamAir hood, i bought a metal lid with N02 bungs fabbed in on fleabay ,no i didnt pay full price for it either they took 110.00 shipped . ..here look http://cgi.ebay.com/ebaymotors/LS1-L...item255b7dc153 the opening on the metal lid i bought appears to be 3.5" or 90mm. I dont have a MAF so... what will i need to order to complete the connection to my TB? i bought a 3.5 to 3" black silicone reducer so far .any hints on installation? i kinda expect it to go smoothly..pic's & info of my progress soon to follow............i kinda expect it to go smoothly

 

+1 id like to see a parts list for the swap, i havent come across one yet. Obviously you need a LS1 lid and some fab skills, a parts list would be nice tho

 

keep us informed how it goes, im considering doing this over winter too.

 

I have a link to one in my signature

 

thanks but,most of that write up will not apply and is unnecessary in my case .I have a RamAir hood which means more room, trimming everything wont be a factor...Mine will look Stock/aftermarket. imo

 

Take it from me, I gave up on my lid conversion because even with the ram air hood you still need to trim a lot off the lower airbox to get the hood to shut. Its not a direct fit

 

Never surrender AhhRRRR!!!!! lol .. i'll get it one way or another ..

 

well then, be the first to step to the plate!

 

All you will need to do is dremel the bottom of the airbox down until the hood closes, just letting you know that so you aren't upset when it doesn't fit right out of the box

 

I'm sorry did you say something? i was starring at your avatars' butt ...
......yea i expect some trimming of the plastic piece just dont see myself having to cut up the car.

 

The trimming of the rad support takes about 15 minutes if you already know what you're doing. You basically want to cut it down flush with the bottom of the 4 bolt holes for mounting it. You WILL have to cut the underside of your hood still. I have a glasstek 4" cowl hood and it still needed to be cut a lot. Whatever you do don't cut the car up like some of the people on here. Some hood trimming can be covered up if done right but you can't bring back pieces of your car if you change your mind later.

As far as the list goes you just need the rad support/airbox, air filter, lid, and about a 1ft long piece of 3" silicon tubing. You can trim the tubing to fit between the lid and throttle body. I would go take some pics for you but it's raining pretty hard right now. Feel free to pm me if you have any questions.

 

Pics of trimmed hood and lid setup?

 

Man, I love my lid swap. I had to cut a junk load of support out of the hood (sunoco 2.5"/3") and completely flatten the bottom of the ls1 plastic radiator cover/lid support. After this was all said and done, it STILL wouldn't close all the way. My solution was to raise the hood latch mechanism up a bit (like a 1/4 of an inch) and now it closes. Hood isn't as flush as I would like it to be, but I suppose that's the price I have to pay to have a Godly part (descending from an LS1) on my car.

 

WORD!
sorry bout tha double post........guess that happens when you are affiliated to more than one technical site sometimes...

 

can you make the lid work on a stock TA hood?
