Mazdaspeed-ing your NB
20 Attachment(s)
Finally it's time to post some pictures of the first turbo project I'm following as full technical support!
The car belongs to a friend of mine (Pit). He works in a garage, so he has great skills in mechanics. I'm helping, learning, giving back some technical tips. His idea is to build a daily driving Miata starting from his stock 1.8L NB. As in Italy we are not allowed to tune our engines, the aim of this build is to keep as much as possible the OEM-like look. The car, as we said, will continue circulating on streets but will be more and more track-oriented. Target is ~200 hp Actually the setup is the following: Chassis: - Rollbar GP by TRLane Fabs - Underbody frame, custom made -- too heavy! It will be replaced soon by a lighter one Suspension: FM Stage II suspension Tyres: Toyo R1-R 225/45 R15 for the moment on nothing (6UL will come soon) Let's build!!! So the first step was to buy Mazdaspeed used components, carters, etc https://www.miataturbo.net/attachmen...ine=1325788079 Then, everything starts with DIY reroute, with aluminum re-welded components, by http://www.racing-radiators.it/ (professional radiator maker located in our city (Turin)): https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 And finally what will go on the front area (with derivation for turbo cooling) https://www.miataturbo.net/attachmen...ine=1325788079 It's time for creating the piping! https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 OEM outlet completely closed http://farm7.staticflickr.com/6102/6...d21502f2_z.jpg New thermostat location http://farm7.staticflickr.com/6231/6...a92f11dc_z.jpg Let's go on with the REAL work: Oil pan disassembling.... notice the home-made engine lifter :rofl: https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 Again it has been decided not to follow what Mazda did for the oil lines: https://www.miataturbo.net/attachmen...ine=1325788079 Custom bended hard lines has been made by Pit (the owner of the car) using: - 10mm - 1.5 meters hard-line pipe tube (standard hydraulic component) - Standard 1/4 plug for 10 mm pipe (standard hydraulic component) - T 1/8 female - 1/8 female - 1/8 male conical (standard compressed air compoent) - 1/8 plug - round junction 10mm (not so common, but availlable on order) - junction 10mm - junction 10mm - copper spacer int. diameter = 10mm These lines are following entirely the engine block! https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 It's time to re-assemble the oil pan: https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 He used white VW gasket silicon, that he experienced to be much better than the Mazda one (but the cost is more or less double....) The oil feed on turbo side is brand new, CNC made from a block of steel: https://www.miataturbo.net/attachmen...ine=1325788079 (the one in the photo is made of aluminum, but a friend of us strongly suggested to make it in steel... obvious but smart consideration due to high temperatures of the turbocharger unit!) In the photos above you can see that the cold side of the turbo is not plugged: originally MSM has the outlet going up, passing into a small pipe and going back down to IC. My friend decided to get rid of this stupid pipe length and to go for the down mounted outlet. Of course the drilling is not coinciding perfectly, but we re-drilled a couple of holes. https://www.miataturbo.net/attachmen...ine=1325788079 https://www.miataturbo.net/attachmen...ine=1325788079 Yesterday night he finished assembling the engine and the piping (pictures of IC bracket etc will follow in the next days) while we started working on electronics. The unit will be a Greddy eManage Blue, maybe with autotune in future. Wireharness has been prepared by MaD, a friend of us which works in Magneti Marelli for engine ECUs. Great job, very very clean! We are solving some small software/tuning issues.... but we hope to be able to give back to street and track the car within 2-3 weeks! Next steps: - new -lighter- frame rails (dedicated post will come.... it's my personal small project) for replacing the underbody frame - 6UL - bigger turbocharger from subaru IHI (this is not scheduled, but I think will come soon anyhow :rofl:) Stay tuned! Full build thread (in Italian) |
Looks like a very solid start. Good job.

Totally dig on the pit under the garage... like an oil change place but at the house? winning.

Are you really using the oil cooler to support the weight of the engine?

Let's go ahead!
Koyo radiator from the backside https://www.miataturbo.net/attachmen...ine=1325966318 And IC assembled behind OEM bumper plastics! https://www.miataturbo.net/attachmen...ine=1325966318 Turbo to IC: https://www.miataturbo.net/attachmen...ine=1325966318 IC to TB: https://www.miataturbo.net/attachmen...ine=1325966318 https://www.miataturbo.net/attachmen...ine=1325966318 Exhaust: here you can see the mid pipe with thermo strips on (not installed for increasing performances, but for reducing heat while driving, as it's still a daily) https://www.miataturbo.net/attachmen...ine=1325966318 https://www.miataturbo.net/attachmen...ine=1325966318 https://www.miataturbo.net/attachmen...ine=1325966318 Out of garage, finally: https://www.miataturbo.net/attachmen...ine=1325966318 Here a shot of the interior (Momo steering wheel + Elise seats): https://www.miataturbo.net/attachmen...ine=1325966318 And let's go to the "out of project" pictures :rofl: A shot of the box: https://www.miataturbo.net/attachmen...ine=1325966318 The "hole" on the bottom was born as a storage for wine.... but it's perfect for working on the car! On the LH you can see a 1.6 NB FL.... ehm, just a part of.... :rofl: The rest is here (in SUV version): https://www.miataturbo.net/attachmen...ine=1325966318 or here: https://www.miataturbo.net/attachmen...ine=1325966318 First startup => PERFECT! Now we still have an headache on EMB wiring (but should be solved right now) and next weekend it's time for tuning :brain: |

:D
https://www.miataturbo.net/attachmen...ine=1327859715 Finished :D Tuning of EMB was ongoing yesterday, but it started snowing a lot, so it was impossible to use torque.... (5th gear, car going anywhere if pressing on throttle over 3000rpm!) |
good job :)
|
You did a very good job of making it all look original. Do they inspect your car every year?
|
Very Nice build!!!!!!!
|
Nicely done.
|
I love the custom re-route, looks like some quality work.
|
This is very nicely done! I wish I had teh welder skillz.
|
I really wish I had the Norman man-cave of a garage, with combo wine cellar / maintenance pit, multi-cord wood storage, and loft space !
Which is not to say I am not thankful to have the space I have now (which, although leaning a bit and possessed of a concrete floor of the shattered and heaved variety, does not leak and is still (mostly) structurally sound) :) And the welder skillz. Edit: crap! thought you were in France ... but now I see you are in Germany/Italy. So I should call it a Teutonic man-cave of a garage then? heh |
