Welding downpipe and intercooler piping. Using a delta fin ebay intercooler with 2.5" ebay aluminum intercooler piping on both sides. Mounted up intercooler and intercooler pipng.
Also picked up an 04 WRX wagon as my DD that on the street. Mostly stock, but new engine swap, larger intercooler and 3" exhaust all the way out, also came with an new Accesport V2... Thinking about an up-pipe for it so the cat doesn't pop and blow the turbo apart, but I honestly haven't even checked it out if it has an OEM up pipe or not.
The pie-cuts for the aluminum elbow are actually for the hot pipe side. In a few pictures down you can't see it, but it runs alongside the driver's side inside fender. 100% wheel clearance. It worked out pretty good too because with the ebay universal piping kit, it ended up being the only piece I really needed to cut/weld besides the cold pipe bungs/IAT bung.
I know a few of you guys are saying lose weight, lose A/C and PS... but I am trying to model this as if it were an OEM setup, just pretending it's an OEM Turbo Miata with all the amenities that would make for a comfortable drive anywhere around town/highway... Not going for super speed... Yet.
I already have a track car that is plenty of fun.
Here is a little more reason as to why I said things spiraled out of control... we've got 3 Miata's now... Whoops. One of the white ones is my roommates and it is turbo.
2 turbo and the blue miata is going to stay N/A. It came with the manual rack and going to keep it that way. It will kind of be my benchmark to test the MPG of the stock N/A vs. Turbo.
This is basically as it sits now. It might now have a huge impact on the MPG, but I am going to use LS1 coil packs because I've already got spare ones lying around and the whole point of this build I've been telling myself to reuse/re-purpose all the car parts I have collected over the years... The down pipe I was able to fit 3" without cutting firewall or anything, so I am going to go a full 3" exhaust even though that is overkill. I have a 3" cat lying around too... and well, you get the idea of what I do with stuff lying around.
Anyone know if the OEM fuel pump will work with what I've got? I've got a Walbro 255, lying around of course, but do I really need to use it?... I kind of figure why not?
Just waiting on the MS3x and I should have everything to be able to fire it up with an open down pipe. Needed to do a clutch job in the blue N/A Miata so that has been taking up all of my time lately, but I am just about finished with it so I can get back to work on the turbo Miata.
The things I have left to do are:
- Get MS3x
- Wiring for sequential fuel/ign
- Wiring engine harness for LS1 coil packs
- Wiring engine harness for variable TPS
- Wiring for coolant sensor at back of head?
- Jack car up and finish welding exhaust
- Fill oil and pour all over fresh head
- Fill transmission fluid
- Walbro 255
- Find some LS1 spark plug wires that will work well to buy
- Get wideband
- Get boost gauge
- Find A/C shop willing to deal with R12... or convert 134a
- Really freshen up/Read up on tuning MS... I've only messed with Haltech UI
- Read up on tuning in general
I've never tuned a car from scratch before, I've only ever had to make small tweaks, and this was on an SR20. Hoping I can find find a good basemap somewhere to start with for my setup... Especially since I will be street tuning without a dyno for awhile. Then finalize with a dyno tune. Want to minimize dyno time if I can.
