Hi All,

I kind of need some help, the previous owner of my car made a mess of the battery tray when he miss calculated the hole and decided to cut 2 circles next to each other to install his FMIC, so now I've got this giant hole in the battery tray that looks like ass. Furthermore, to make matter worse, he used tin snips on the hot pipe side to fit the home made cooler piping in. It's terrible as you can imagine.

Just wondering if anyone can re-weld up these ass of a holes and re-cut nice perfect circles for me and make it look nice an tidy from top and from below.

I don't mind home jobs as long as it looks good and clean.

If anyone can help and for a reasonable price, PM me...

Cheers,

Johnny

Welding a recutting holes could be a pita.

Have you thought about grabbing a die grinding burr and grind the holes out to the new round (or other) clean shape.

Easy to do and you could even do it with an electric drill instead of a pencil grinder if you don't mind side loading the bearings for a while. Given it is only light plate it shouldn't hurt the drill much if at all.

If you go down this path I would suggest spend a bit of time taping joints etc where the grinds may end up. Once they get stuck in a join etc you will never get them out and they will rust leaving a shitty looking mark.

If the holes work out a bit oversize just make up a rubber sealing gasket or run in some pinchweld edging and make it look like that was how it was meant to be

Well legally tany hole cut in that area must be reinforced to return the rigidity back to that section of the car, so if you are willing to have someone weld in a reinforcement plate that has a clean hole in it then you are also less likely to encounter any stife from it if one day you go to engineer the car.

ok so here is what i would do if i was to keep that piping design.

Remove the pipe, weld in a patch panel of 0.9mm body steel, from the underside of the chassis. Then make a new hole for the piping around 3.5" and slightly forward as it seems to be rubbing on the front section. test fit to make sure all is smooth and no fouling.

Then, i would paint both sides of the patch with an etch primer then some chassis black paint.

get some cardboard and trace out a piece that will cover the battery tray right the way under the guard mount, all the way to the wheel well and back to the chassis rail towards the centre of the car.

Use that piece to cut out a Flat sheet of 2mm polished alloy so you can cover the entire area. mount that with screws into teh old tray. then you can cut a matching hole in that from underneath to match the bottom hole.

use that alloy sheet to remount those wires, install a catch can, radiator over flow.... etc etc etc

------------------------------------

If you want it done as cheap as possible, you could follow the above, then cut out your patch panel and the patch, needs to me no more than 1mm gap all around, then just take it somewhere to get tig welded up, might cost you $50 to weld it depending on how good your cutting and patch is.

      Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys

      Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels

      Hypergear Turbochargers and High flow Services Development thread

      Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)

      I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.

      Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
