Hey all. If your reading this then i need your help.

All you need to know is the car must be a 2G! That is very critical.

With the design of my 2G subframe now complete and near welding phase ready for testing i want to aquire some data to allow me to get the built in lower brace right and this is where i need all your data!
I need to know how low your Exhaust Downpipe is. So if i can get this info listed below that would help greatly.


Details i need are...

Engine type
420A - 2.4 4g64 - 4g63 fwd - 4g63 awd

Downpipe make (brand) / has it been modified
If its a custom one, is it made by someone who makes them for us all the time (same jig) and name
DP flexi location (i.e under the oil pan or after the oem subframe)
DP size (example 2.5" OD)
If you currently use a Tanabe lower brace and if it fits through that ok

If you have a picture from the side of it that would help visual it also if its possible. No worries if not.

The location i need a measure from is in the picture attached, its the lower dip in the oem subframe and its to the top of the DP and then i can add the OD size to that and know the lowest point.


This data will help me average out brands systems to know what the built in lower brace should be at to work with all.

Thank you everyone for your help on this data.

Hey, sorry. A lot of sh!t happened at work and I had to stay longer, and forgot. Here's your info.

Engine type
4g63 AWD

Downpipe make
Magen not modified

DP flexi location
Under the oil pan

DP size
3.0" OD

Here are a couple pics. Was a pain to get a good enough one, and have it be level. I believe the bottom pic is the more accurate one.

Thats perfect thanks for that dude.

Just to confirm as the pic is throwing me off a bit. It looks like it starts 2.5" down but ends at 5" down but adding them would mean 5.5" finish. Is it the angle of the pic and it starts around 2" down?

I know its tricky doing both and getting a great snap.

Thanks for this it really helps. Perhaps the awd and fwd ones are completely different due to the transfer case. Which would be weird as it still follows the same lines and pan shape! Hmmm hopefully i get more data to show this is a pattern

I was quite surprised myself. I was not expecting it to be as close to the subfram as it was. But I'm not sure. Plenty of people swayp to awd and keep the fwd front subframe (to my understanding). But I haven't looked into that much as I have zero intentions of converting to awd.

The turbo frames are the same for awd and fwd turbo. So nothing changes there. Its got to be placement for the DP, its the onky thing i can think of as if the prop shaft is in the middle then the awd exhause has to sit lower then to sit along side that which would make sense i guess. Maybe i just answered my own question now i have had a think on it LOL
 
I just hit up a bud of mine with 1g fwd and another with a 2g gs to comment on this. Get you a few more inputs.
Cheers for that, it has to be 2G though for the data to check against
