astral's Haltech Turbo NA Build
Hey everyone. Been putting this thread off for a while out of laziness, so there is a lot to update all in one go. Hope you all enjoy this thread as much as I am enjoying the build.
So let me start off with a few photos of my car. The car is a 1994 C Package with ABS. I purchased the car 2 years ago, with 117,000 miles. It's an OEM (original paint!) Brilliant Black, with original factory hardtop with headliner and defroster. The car came with an inch of maintenance records, roughly 4 owners. Decently clean car, no frame damage, no structural rust. The car came with a hard dog ace roll bar, TR Motorsports 15x7 wheels, and FM Vmaxx xxxxxxxtreeme (shit). I threw some 15x8 RPF1's, Dunlop Direzza ZII 205's, lots of fun interior bits (garagestar, revlimiter), FM frame rails and a few other stuff. This quote is taken from post 2, to make it easy for people viewing the thread to see.

https://cimg1.ibsrv.net/gimg/www.mia...1853c5a999.jpg After a compression/leakdown test gave me 157, 160, 130, 160 numbers, I seriously contemplated starting a serious build with the car. Then this happened. https://cimg9.ibsrv.net/gimg/www.mia...f1b4a77784.jpg Blessing in disguise. This damage caused me to rip the car apart and go all out with it. I bought a super clean OEM brilliant black door, and started ripping shit out. https://cimg3.ibsrv.net/gimg/www.mia...374cde4f00.jpg https://cimg7.ibsrv.net/gimg/www.mia...5d45c8a024.jpg Started laying down this thermo-tec supressor, and cleaning up all the surface rust around the car. https://cimg6.ibsrv.net/gimg/www.mia...4930311c6c.jpg Swapping the wiring over from the 1.8 dash bar to the 1.6 dash bar for my NA6 dash swap. https://cimg8.ibsrv.net/gimg/www.mia...7b0184bd64.jpg Garagestar Fender Braceshttps://cimg9.ibsrv.net/gimg/www.mia...6ef3f5bc21.jpg DIYRoadster Door Bars and Blackbird GT3 https://cimg3.ibsrv.net/gimg/www.mia...9615e988dd.jpg https://cimg0.ibsrv.net/gimg/www.mia...ece867f19c.jpg |
And now the fun stuff begins. For the turbo build, here's my parts list.

And now, more pictures! https://cimg6.ibsrv.net/gimg/www.mia...609d2d7e91.png Cleaned, inside and out, all seals redone, Cometic head gasket with ARP headstuds, JDM BP4W. https://cimg7.ibsrv.net/gimg/www.mia...25ed3eb56b.jpg Old engine coming out. Now before I get shit for not doing the work myself, I am not a natural wrench. I love driving, and wrenching is good fun too, but I am not confident in my abilities to properly set up a car. I would much rather trust the car to my buddy Richie and his techs, who have done this exact job millions of times on a shit ton of Miata's. VL Motorsports in Livermore, CA. In their yard you will find a few FD RX7's; FB's, and FC's, turbo and supercharged Miata's, a rack full of 10 or so rotors and rotor housings. These guys are good. Shameless plug. They use Haltech Elite's in all their cars. They use a dynapack dyno. https://cimg5.ibsrv.net/gimg/www.mia...6a0490d17e.jpg https://cimg7.ibsrv.net/gimg/www.mia...c9596d915e.jpg https://cimg2.ibsrv.net/gimg/www.mia...3b82acab8d.jpg Good fun! |
Just wanted to share Richard's car. He is one of the owners of VL Motosports. Thought many would enjoy checking it out.
It is running a built 1.6 (I know I know, many here will disagree. He built it as an experiment, but I'll let him chime in and comment on it. ) It is the Begi Alpha Omega Kit, GT2860, Ohlins Suspension, some stiff ass clutch. And of course, (in progress) running a Haltech Elite. https://cimg5.ibsrv.net/gimg/www.mia...76a8ce2f8d.jpg https://cimg7.ibsrv.net/gimg/www.mia...6ca89f8ad4.jpg https://cimg1.ibsrv.net/gimg/www.mia...8e335bf27c.jpg |
Build looks promising, and I can always appreciate a clean black and tan. You and I seem to share a similar philosophy of "Buy once, cry once.", although I can't say that I've done a good job of executing upon such idealism thus far:). Good luck with the build!

I love seeing all the nice details for street use, like replacement rubber bushings instead of poly. If you don't go all the way with the bronze sleeves, rubber is definitely the way to go over the plain ES kit.
PM me if you need to borrow a press to get those in :) |

Couple more fun photos.
700/400 Xidas https://cimg2.ibsrv.net/gimg/www.mia...be5b57ee9f.jpg And of course my turbocharger. https://cimg3.ibsrv.net/gimg/www.mia...17278a221b.jpg |
A couple photos showing some thought process behind the parts I decided to go with. (BP4W and FM DIY Kit)
BP05 Head vs. BP4W Head flow angles. https://cimg1.ibsrv.net/gimg/www.mia...e60b572b14.jpg I know anyone can fab a cold air box like this up, so this really isn't a Flyin' Miata shill post, but they had a great image on their website of the thermal readings when using a properly set up cold air box. This combined with the (soundly engineered) NACA duct headlight should be real good for intake temperatures. https://cimg4.ibsrv.net/gimg/www.mia...d72b22d47e.jpg And while I anxiously await my car being ready to drive, here's a shot of a car I saw. 993 Carrera 4S with what looked like a pretty rare package. Carbon buckets among other little trim pieces here and there. https://cimg2.ibsrv.net/gimg/www.mia...3b41739e4c.jpg |
Nice build! I sent Richard an Elite 750 Base map for a 1.6l recently. Must have been yours or his.

Here's a video engine getting pulled at VL. >5mins |
Did you have any trouble with the DIY door bars lining up with the holes for the BBFW roll bar? Still haven't installed my roll bar yet, and would love to add door bars.

What I would recommend is to have your BBFW bar completely installed besides the main hoop (the part that drills into the panel behind the seats where the DIYRoadster bars will be going). Have someone hold the bar out towards the door sill to where it will be bolted on the floor, and then just drill through both bars on the rear deck. The drill bit will just take the path of least resistance. I originally drilled through the blackbird bar, then tried slotting the DIYRoadster bar into it. It was much more difficult to get it done with the hole already drilled in the rear deck. https://cimg9.ibsrv.net/gimg/www.mia...99eb899580.jpg |

Couple photos of the car as it get's finished with it's engine swap, and getting ready for smog.
Pretty 949 suspension components visible. Also now sporting a 949 sport puck sprung clutch with flywheel. https://cimg3.ibsrv.net/gimg/www.mia...ba2a7e99e1.jpg And the BP4W in it's currently unbuttoned state. https://cimg7.ibsrv.net/gimg/www.mia...9d20e34fce.jpg |
Okay. Took my car out for a drive today, completely bone stock NB engine with all emissions equipment, stock exhaust, etc to pass smog.
The car has a stupefying amount of drivetrain noise. 949 10lb flywheel, garagestar delrin mounts, AWR engine mounts. What's the biggest culprit lol? And to all the dudes who pushed me to 700/400 Xidas, they are brutal. I've got them on 5/6 clicks. I am strongly considering dropping to the 550/350 rates. |
awr mounts likely biggest
|
I have Xidas with 700/400 rates, too, and I think they're more comfortable than the Koni yellows/ FM springs that they replaced. However, I did go with the NB top hats, so maybe that has something to do with it.

^ What he said. Just run full soft on the street and report back.
Also the delrin mounts transfer a boatload of diff noise. All sorts of clanks and bangs, especially on decel. |
