supercharger engine lid

Post by Stuart Davidson »

I wonder if anyone can tell me the mods I need to do to fit my supercharger engine lid to my na? The catch is obviously in a different place, so something needs to be moved I guess? Thanks.

I had to do this on my conversion. I drilled out the spot welds, then bolted it in the new position using the original drilled out welds as mounting points for the bolts to go through.

It worked fine, though the catch was not as securely mounted as it was when welded. In saying that though, it worked fine:

Think i sealed it with duct tape! I wasn't overly bothered though as it was a car i only used on track and on odd occasion on the road (normally going to the track and back).

In its original position:

After moving it so i could get the intercooler mounted properly:

sure I have seen somwhere a catch made from 6mm rod that fits to the lid so that it locates into the NA catch mech on the body
it looked a very simple mod much easier than drilling out the spot welds and reattaching the catch
could have been on padandwheels or maybe kbox

f..king age you know you had stuff but f..cked if you know where #-o

Thanks for the help, I've got something to go on now. If I get stuck I'm sure someone will give me a tenner for it.

I cut the old latch out of my lid and made a new one up. I had a 'U' shaped length of 6mm bar welded to a couple of pieces of flat steel, one being 'L' shaped piece and the other straight. I then bolted these to matching pieces of flat steel that I placed between the skins of the lid. Hope that makes sense.

EDIT: Corrected to what I actually did but didn't remember!

Drill out the spot welds on the NA latch. Move the NA latch over to the center more to line up with the SC lid. Weld the latch into the correct SC location. If you have an NA engine you may have to grind a half circle out of the bottom of the latch itself to clear the intake. Then, of course you will want to do some minor painting to touch up the area were the NA latch was.

By doing it this way it looks factory. But, creating another U shaped catch is fine also and probably a lot easier if you can't weld or don't know someone that can weld it for you.

You also may want to use a SC prop rod.

Just a thought, but will a SC bulkhead latch retro fit a N/A ?? If so I think Jon at toyotasports breakers (Lincoln) is breaking one - so could be worth contacting him.

Thanks again for all the replies.There's obviously at least a couple of ways of going about it. It's either alter the car itself, which is a bit of work because of the spraying really. Or to alter the lid itself, which might be the easiest way.(Hopefully even easier when dex sends a photo). Thanks , Stuart.

This picture shows the modification I did to my engine lid to get it to fit the standard catch position on a NA car. This is is a temporary condition until I get my conversion done, hence the plastic bolts and two of them missing! You'll have to excuse the dirt, the engine's on it's last legs and all the crap gets thrown up onto the underside of the lid when there's no under tray.

The trouble is, doesn't the standard catch position get in the way of positioning the intercooler correctly?

Its been a few years since i had my converted SC, but IIRC i'm pretty sure it did, so i had to move the catch anyway.

Yes, the standard catch position will interfere with the stock intercooler on a SC but for NA's the lid modification seems simpler. I've done mine this way because I'm going for a chargecooler instead.

Thought your mod was neatly done! - Makes more sense than moving the bulkhead mounted latch IMO.

Moving the bulkhead mounted latch is the best way IMO. It makes it look like it's OEM/Stock. I didn't want to cut up my SC lid or drill into it in anyway to attach a latch,etc. Mine looks like it came from the factory since the bulkhead latch was moved over into the SC location.

Sure, the quick and easy methods are fine.. But, there certainly not the best way.
