HEY MIATATURBONET BUDDIES!
I redid my initial post because I can't update my old one and I feel like I left a lot out. And I've learned a lot more since the install anyways.
2000 Miata LS 1.8L (you can probably use some of this info for 1.8 NA's and 1.6 NA's too
-Long story short, I bought the car bone stock in Feb 2011. Suspension and wheels went on a few months later and then I pieced together this turbo kit in the fall later that year. Here I am, roughly a year and a half later, (turbo kit installed sep 2011and today it is May 26,2013) and the car is still running strong, turbo spools just like it did day 1 and it has NO shaft play at that
Purpose of this thread: Heads up to fellow miata owners looking to boost or modify their current setup. I made mistakes first time around, and have corrected almost all of them. This was done a legit BUDGET, and I dare say it compares to the pricier pre-fabbed kits they may be out of your reach at the time like they were for me. I did lots of research and questioning before taking the journey (not my first rodeo boosting cars as I came from building many 240's before this awesome roadster) Hope I can provide some guidance.
1) What you will need and prices:
-Godspeed T3 Super "60" $250 (in most pics you will see a garret t3, ignore this, it went to **** after 2 days of tuning and then i picked up the godspeed and have not been let down at all, it's in the later pics)
-Flyin' Miata cast turbo manifold $421 (choose your manifold wisely but I love cast iron, and the relief cuts)
-Exhaust manifold gasket $10
-2.5" downpipe $100
-2.5" 5bolt v-band swing valve $35
-Vband clamp with flange $25
-Internal wastegate actuator $42
-NGR Type S BOV $155
-BOV flange $17
-BEGI vacuum block $43
-I/C and Piping (CX Racing) $164
-Oil Feed: Sandwich plate from glowshift.Fittings and line from summit. $77
-Oil pan fitting $6
-Flyin miata boost gauge $66
-AEM digital uego wideband $173
-Rx8 425cc injectors $100
-Brain Built MegaSqurit 2Extra $650
-Penzoil ultra synthetic oil w/ filter $31
-NGK BKR 7E-11 plugs or Champion counterpart spark plugs $11
-Flyin Miata Level 1 Clutch $365
-Lots of heat wrap, titanium, wrap, and/or turbo blanket $150
-A-pillar dual guage from flying miata $50
(and ignore the stupid t2-t3 adapter in this, i was oblivious to the fact the fact it was not going to fit until i looked at the bay again, haha. silly me)
-------Total around $2,941 Now sure you can find some of the parts listed cheaper, or perhaps go a different route on some things to save. Keep in mind; intercooler piping, downpipe, and exhaust are not factored into this estimate. I was able to get all of those for no more than $250 all together. All depends on who you know. But you will have a standalone ECU with plenty of tuning capabilites, A/C will still be in the car, and you have a nice clutch ready to handle all the power (my stock one lasted about 3 months of abuse after boost) for $3,000?? That is not bad at all.
On a hot/humid day. I was able to make 185whp. Tune is very conservative, and the wastegate holds ten for a little bit then drops back to 7psi and holds. I'm investigating correcting this and holding 10, and or 12 psi. The car pulls pretty strong, I've beat some cars I shouldn't but power to weight is an awesome thing. I'm sure after sourcing colder air, and machining out the turbo mani some, I can achieve desired boost levels. I have plenty of fuel to play with.
Purchased and returned (after use) a Unitbit piece from lowe's for $40.
Purchased and returned a tap for the 3/8 NPT for $10
I used a 3/8 hose barb for the fitting. onto pics
Once the hole is drilled, you can use your pinky to reach in and remove any filings. I kept the bit greased at all times, and would clean off and regrease again often to help control the metal from winding up in the oil pan. The tap works great and jb weld was used on a few of the last threads to seal it off
You now have your oil return taken care of, next post is oil feed
