The time has come for me to begin parting out my turbo Miata. I slowly built this car over the last 5 years with high quality parts and high performance in mind. I had finally reached my goals in the build last year when an opportunity to buy a V8 Miata came up that I couldn’t pass on. Sadly, I can’t keep both cars. Take advantage of some nice parts at nice prices!
TSE Built Motor
This still very fresh motor was built by Andrew Kidd at Trackspeed Engineering and includes a whole lot of nice upgrades. Go to the website and price it out yourself and you’ll be pushing $8k. It will handle up to 500whp and rev smoothly to 8500rpm (I kept my redline at 7.5k, and typically shifted before that). After it’s initial 250 mile break-in period last year, it only saw about 3 hours of track time and about 1000 street miles and was boosted to 300-325whp. Here are the details:
99-00 short block with VVT head (99-00 bottom for better coolant routing, VVT head for more power)
8.6:1 84mm (1884cc displacement) Supertech pistons, hand-finished and thermal coated
Wiseco XX rings
Manley 130mm H-beam rods
Boundary street/strip billet oil pump
ACL race bearings
ARP head/main studs
Full race port/polish including chamber deshroud
Supertech stainless +1mm intake valves
Supertech inconel +1mm exhaust valves
Supertech "heavy" double valve springs + Titanium retainers
Supertech shim-under-bucket lifters
1/2" NPT bung in oil pan for turbo drain
SuperMiata damper + 4T trigger wheel
VVT oil line has been swapped with stainless steel AN line to accomodate LS Coil bracket
EFR 6258 Turbo
2000 deg thermal coating by Full Race
T25. 0.64 A/R
V-band turbine outlet
Comes with low and medium wastegates
Brand new install for 2016 season (I accidentally killed my previous 6258), has only seen about 3 hours of track use and about 1000 street miles
Right now, it is mounted with Stage 8 inconel hardware to my ARTech-built exhaust manifold (see below)
ARTech Full 3” Turbo exhaust with turbo manifold
This has been on the car since 2014 and has seen the most use, but it's still very functional
Top mount turbo manifold for EFR6258 (or 6758) on NB1 chassis
Magnaflow hi-flow muffler and resonator (gives the car a notable, deep presence without being obnoxious)
All V-Band clamps
Swaintech White Lightning Coating on manifold and downpipe, painted silver
Currently, manifold and downpipe are wrapped in DEI titanium exhaust wrap (yes, Swaintech coating and exhaust wrap, I was serious about keeping underhood temps down!)
The stage 8 inconel hardware will come with the exhaust manifold
Please note that this exhaust manifold will interfere with the stock water pump inlet/mixing manifold, and it will need to be modified. I found the best solution is to change to a front inlet mixing manifold. I have a front-facing water pump inlet made by BEGi that I can include for free.
LS Coil Kit
This includes LS3 Coils (PN:12611424), Magnecor wires, OEM GM coil harness and Singular brackets for a top mount over the valve cover. I initially bought hardware from a FM Big Spark kit, but the mounting behind the engine was too tight for my taste and I changed to the top-mounted Singular brackets. The Magnecor wires were from the FM kit and are therefore longer than necessary for the top mounting, but they still work. This comes with a stock GM harness that I wired into a Weatherpack connector for easy removal. This makes the connection to the coils "plug and play", but you will need to wire up your own solution for connecting the ECU/engine bay harness to the GM LS coil harness.
Squaretop manifold
Comes with throttle body
