I just bought a couple sections of bends (2.25") and am cutting them and welding. I bought a 45 degree and a 180 degree J bend. All .063" wall 6061-t6 AL. I also cut the stock Greddy hotpipe that goes from the core to the fender so I can rotate it to come out the side of the frame rail instead of up through the fender. I'm also using a 2" to 2.25" 45 degree coupler off the turbo and either a 45 degree or straight 2.25" coupler to go between the modified greddy pipe and my custom hot pipe. After I get them made, I might model them and put them into a drawing and see if I can get them made via CNC Mandrel Bending to cut out the welds.

For the hole, I used a 2.75" hole saw on my 1/2 drill. Going to get some edge trim to put along the edge of the hole to make it look cleaner and protect the soft AL piping.

Are you talking about the turbo elbow pipe (the upper downpipe)? If so, it's just the Full-Race part and yes it clears everything. I also recirculate my 44mm WG into the Lower DP.

I made all of my own lines except the oil feed line. It's super easy, lol. I got my supplies from Summit racing, and you really don't need the "special tools" and what not.

Sweet deal! Off the top of my head (all -6 an stuff), 3 swivel 90 degree fittings, one straight fitting, hose, and a swivel extension for the block side coolant port. I also ran an S14 Coolant pipe (the one that goes under the CAS) so I can run a coolant line there, and I cut off the wrap around pipe that goes behind the head. Now both my heater hoses are the same and fit correctly. No more 180 crap behind the head, ha ha.

No, I used a standard 5/8 High temp heater hose with AL exhaust tape wrapped around it as a temp drain. I plan on doing a nice trick oil PCV setup with that integrated in it, so I am leaving it alone for now until i have the time/money to get it designed and made.

Stock fuel rail, Tomei Sdj FPR, Tomei/Nismo 740CC injectors (going to limit power, I know, lol), Walbro 255 pump. Going to rewire the fuel pump soon due to the crap wiring from the factory. Next year, I'm planning on a fuel cell, top feed rail with larger injectors. Also going dry sump next year, with my own design engine mounts to set the motor further back and lower than it currently is (as much as I can without being set for failure, lol).

yeah i am going to re wire my fuel pump here to, just waiting for my 2nd pump to come in and i will do them at the same time. you know what wires and stuff for hardwiring, i have been reading all over about them, mostly think i will by pas the plug and use the signal wire going to a new relay straight from the battery then use the same signal wire going to a 2nd relay for my 2nd fuel pump

I haven't done too much looking into it yet, but basically what my plan is; is to wire in a cable directly from battery, operated by a relay with the ignition signal wire, to the pump. So basically what you have in mind, ha ha. I'm also going to relocate my battery eventually to the rear just before the rear "axle".

I was going relocate mine to, but then I got an xray machine battery, thing has some cranking amps, for free. When they replace one them they have to replace all of them. and it fits perfectly on the battery,tray with th we intercooler piping.

Awesome! lol. I just have a miata battery currently in front. However, I'd like the weight to be more rearward for weight balance reasons. :biggrin:

Not much of an update I know, but here's a pic as of tonight, lol (sorry for the crap cell phone camera).

I've decided to redo my downpipe, so I'll be making my own. After making my own IC piping, this stuff is easy, ha ha.

Lol, I'm talking about the downpipe, not the turbo elbow that Full-Race calls a DP. Also, for the money and fitment, the Full-Race "Downpipe" isn't that great. The o2 bungs are in crap locations (the lower two), causing the sensors to be VERY close to rubbing on something no matter how you orient it.

True, but for how much they charge for the damn thing, you'd expect it to fit perfectly, ha ha.

It's all about money for me, lol. I have all the parts I need already, just need to save the money for the tune. I know I still have work to do before everything is ready to get tuned, but it'll be done before I have the money to tune it! Things keep coming up that I have to spend my car fund on. Just recently is $350 for a vet bill for the cat...

Portland, lol. There are plenty of shops to choose from for tuning here. I'm leaning towards Forged Performance for my tune now. I was going to do Portland Speed Industries, but have lived here long enough to hear "things" about them that make me choose otherwise. Forged has an AWD Mustang Dyno as well, so I can use them later on for my Celica Alltrac, ha ha. I also prefer mustang dynos.

Nice! Let him know to sing up on 3SGTE.net! lol. I hate to admit it, but the 3SGTE sounds a lot nicer than an SR20DET. At least in stock form with just an exhaust.
