DIY install 99% finsihed. NOW WITH PICS!
Hey guys.
I have been installing my kit on the weekend an in the evenings this week.
I went for the first test drive last night - low timing and running rich for safety, man, this is SOOOO FUN!
The kit:
t25g
ebay stainless mani
diy dp
emanage blue (not tuned yet)
305cc supra injectors
ebay front mount with alluminium piping and silicone bends.
rx7 afm...
So simply, yet so effective. I haven't been taking many photos cause i'm up to my elbows in grease, but I just wanted to share!
Something I want to know is: I have a wideband still to install. Should I run it all the time along side the stock one, or do they deteriorate quicker than the stock ones? I have a Digital A/F ratio guage (the autospeed/jaycar one) which I want to use for tuning, but I don't know if I should leave it in there, or only put it in when tuning is required.
What do you guys do?

I just installed my wideband recently. I welded the bung 5 or 6 inches before the cat. Seems to be working fine for me, except there seems to be a bit of a delay in the readings and im not sure if that is how far down the pipe it is or if it is because I am running the stock ecu with only an AFPR and an Throttle body from an automatic which seems to not work right with the ecu because im reading stoich on decelleration.
Anyways, i think its better to install a bit downstream from the turbo and running every day should not be a problem other than maybe needing a new sensor in 4 or 5 years.

just out of curiousity, how is the response of your gauge when it is closer like that? I feel like I might be getting a bit of a delay, or maybe not. When i step on the throttle, it seems like it does not adjust immediately. maybe thats normal idk

yeah, same thing here. You have a test pipe right? I was thinking possibly the backup that the cat creates could cause some issues with getting a good reading but if you are seeing the same thing with a testpipe, i doubt that its affecting it. You know, its probably completely normal and I am just ----.

Well, what can I say. I started putting time and effort into a turbo kit on the 7/9/06, and turned the key on the Wednesday 14/3/07.
I wanted to be on the road the whole time, so I had to collect little by little.
Fast - Cheap - Reliable: Pick any two. This is the formula for modifying a vehicle. I chose cheap and reliable, so I'm never going to be pushing 150rwkW out of this baby, or dragging Skyrines from the lights while both wheels scream with smokey pain...
What I wanted: low down torque, and enough power on tap to be able to overtake when you need to (for road driving, that is the only reason to go FI IMO). The track is another story!
I started looking for bolt on kits, but nothing anywhere near my price range included an intercooler. A must in Brisbane heat IMO if I want "reliable" to be my choice. The more I looked, the more I realised that a lot of those kits were missing essential parts, or contained parts that would need replacing. After finding www.miataturbo.net I decided to build a DIY kit with what the parts I wanted to have, at about the same price as pre-built kit from GReddy. Obviously my power goal was to match the stock GReddy kit, (so, nowhere near "fast") but produce that power more safely with an intercooler and a better fuelling system.
The basics:
T25g turbo from an SR20det from a 180SX
GReddy eManage piggyback - fuel and timing control, as well as a very cunning closed loop device for while on boost
EBay intercooler
89 Toyota Supra 305cc Injectors
Heaps of custom stuff (fabbed with the help of several very good mates! )
Here are heaps and heaps of pics (some are of the same thing) that are in no particular order.
