Hello all. I'm sure some of you know about a certain vented engine lid that used to be offered by another member in the MR2 community. Unfortunately production runs have fallen short of demand and expectations on that item so I decided to make my own design of a vented engine lid for the mk2 MR2. It is currently a work in progress but upon completion there are plans to have my design reproduced in both carbon fiber and fiberglass options if there is enough interest. I am fabricating a set of hood scoops from a 69 Chevelle hood to fit the metal N/A engine lid.

All I've done so far is cut out the scoops to properly cover the vents:


Next I will trim the pieces to properly fit and tack the scoops in place with a bit of a bend at the open end to increase the height of the opening to be larger than how they sit in my current picture. Once tacked in place I will be welding all of the way around the seam, grinding it smooth, then my body guy will make the finishing touches as needed. Upon completion I will send my design out for a mold to be made for reproduction if there is enough interest. Otherwise it will simply mount on my car and I will have a one off engine lid. Please feel free to offer your opinions and express your interest in a carbon fiber or fiberglass reproduction. Also, as you can see I am using the N/A engine lid to build from. Plans are for the reproduction to have the underside of a turbo engine lid (not the N/A lid) so you can still mount your turbo model rain guards if that's what you'd like to do.

Oh and if you're doubting my ability to get the metal work done properly then check out my modded trunk lid:

Making progress!!! I spend some time on it today. Got as far as trimming the vents up, fitting them to the lid, and securing them to the lid. It was a pain to make them even but everything is measuring up nicely. I intended to have all of the welding done by the end of tonight but I ran out of gas for the welder so I will have to finish up my portion of it next weekend. Once the welding is complete I'm going to make sure the openings are shaped exactly the same. From there my body guy will make the finishing touches. If there is enough interest I will send out the finished lid for a mold to be made so that we can make carbon fiber or fiberglass versions of it to sell. Make sure to post if you'd be interested in having one made for you. Thanks for looking!

Ok so I finished up my welding of the vents to the engine lid last night. The lid is a bit warped from the heat now. I tried to go slow and weld small sections at a time as to prevent warping but the metal is so thin that it likely would have warped no matter. I'm handing it over to my body guy to rework the shape of the lid now (basically undo the warping). He said no problem... From there I will be working on the openings to make sure they match each other and I will look into adding a thin strip of metal to the openings to give them a bit of a lip. I think it will look better that way instead of having a sharp metal edge I currently have at the openings. After adding a lip and my other final touches have been made I will hand it back over to my body guy for the last bit of body work. Beginning to see the light at the end of the tunnel. For your viewing pleasures I snapped a few pictures of it yesterday on the car before I finished up my welding just so you could see how it looks on the car (though incomplete). Sorry the pics aren't the best. Hope you like what you see.

Decided I'm going to form and weld a thin rod to the opening of the vents to give them a rolled look at the openings.

eh... maybe not... ended up catching a cold or something so I never went in this week. I'll jump back on it soon.

Sorry not much for updates at this time. School has ambushed my time. I will see if I can get something done on it this weekend. I just purchased some thin round bar to weld onto the edge of the openings so the openings have a nice rolled edge to them instead of just the sheet metal edge that is currently at the openings. Last I worked on it I cut away some of the underside that the NA lids have to give more of a free flowing vent but this left it quite flimsy. Seems like I took a step backwards by making it week and flimsy but I also bought some round bar that is a bit thicker to strengthen up the underside so it is not so flimsy. Do not be concerned about what I'm doing on the underside if you are interested in a carbon reproduction upon completion because the carbon fiber model will be formed using the underside of a turbo lid. Hopefully I can get to it this weekend and will post up some progress. Sorry for the delay guys. School blows!

Sorry its been so long guys. Life and school has been sucking up all my time. I've also been holding back on you a bit. After I got the vents all welded up the lid was wavy (due to heat in super thin metal), then I cut the underside panels out for air flow resulting in a super flimsy and bent out of shape lid. Needless to say it was looking bad. People were telling me I screwed up and that I should give up on it..."There's no bringing it back"..."Throw it in the trash"... I was in a tight spot. I didn't give up though. I put together a wood frame so I could lay the lid upside down on a flat surface without damaging the vents.

Using the wood frame allowed me to flatten out the warped areas and weld in a frame by using two turbine housings, a complete turbo, and a starter to weigh down the corners while I welded in the support frame. (ya ya I know one of the beams looks a bit off... I cut it a bit too short... no big deal)

As of last night the lid is straight, flat, and just about ready for my body guy to do the finishing touches. He likes what he sees. I'm not quite ready to hand it over to him just yet though. I've added rolled edges to the opening to the vents. Before doing so, I also made sure the end of the vents were very even by sticking sand paper to the side of a piece of wood from my now disassembled frame to even out the vent openings (you can see it in the background of the last pic). Then I tacked on some thin rod to give the openings of the vents a rolled edge instead of an unfinished metal edge.

This is basically where I left off last night. I plan to finish my metalwork next weekend and hand it over to my body guy for the finishing touches. We're waiting on higher temps here before we lay down the paint. Build thread coming soon... For now I leave you with this:

I'm very happy with the way this is turning out.
I love proving people wrong. (not directed at anyone on this board)
I'm glad I didn't give up.

Keep in mind that if these end up being produced they won't be made out of metal and the underside will be like the underside of a turbo lid so you can bolt on already produced fan kits and won't have the crazy bracing I have here.
