nos92mx3 had owned this MX for several years and some of you know of the car. Under the CF hood is a 1.8 BP with a T-Bird Turbo Coupe Turbocharger and an AEM FIC fuel controller sending signals to 550CC injectors. The car is stupid powerful and is capable of blistering the hides at 50mph by simply jabbing the throttle to the floor in 3rd gear. The engine internals are stock and said to be on borrowed time along with the tranny (haa haa haa in a wicked voice). Heavy doses of Meth in the form of winter windshield washer fluid injected at 250psi help to curb detonation at pressures well over 1 bar combined with very liberal timing. Needless to say, the prior owner had a feel for this car and knew exactly where it’s limits were. I have big shoes to fill as the new owner.
One of the first things I need to do is replace the Meth injection system because the original one now resides in Rynn’s WRX. So, for the time being we have backed the boost down to around 12psi. I will add a Devil’s Own boost referenced injection system as soon as funds allow.
As you can see by the two engine compartment shots, there is a bit of spaghetti theme going on under the hood. Allthough the previous owner is more than compitent to make a 300 WHP MX-3, he will be the first to admit that he is lacking in the neatness and plumming department.
I plan on cleaning up the wiring and plumbing ASAP along with a relocation of the battery to the trunk. In this pic, you can see the exhaust piping coming off the whastegate. It stayes divorced and never connects back into the exhaust system. When the gate opens, the car gets loud...lol.
When I got her home, the first thing I did was to clean out the interior. The driver's window regulator needs to be replaced thus the door panel is off. I have the part, so it will get remedied next Wednesday.
Not sure why so many of the interior panels are off, but I will get them put back on soon. I didn't bother to vacuum with my wimpy shop vac because tomorrow I will use the mack daddy vacuum and extractor at the dealership where I work.
I love this! It won't wash off.
I spent a very limited amount of time with the soap and water mainly to wash of the dust and get the glass clean. Hopefully, I can paint it before winter, but for now, I will give it a rat rod black rattle can job as they seem to be popular here and I'm a pro at it having done both my Civic and G20.
I want to re-fab the downpipe out of 3” 321 stainless (I have TIG at home) followed by complete exhaust. A MegaSquirt stand alone is on the shortlist as well. This will integrate the systems so to speak. Right now there is a factory EMS with fuel control piggybacked, separate boost control and meth injection on its own as well. With MS, all of these functions can operate from the EMS and timing control can be added. The car has a slight hesitation off idle and sometimes can be hard to start. These problems can be dialed out with the MS EMS.
Since the car was originally an RS model, it’s equipped with drum rear brakes and my intention is to autocross and track the car, so I will pay attention to the braking system. Planed are a rear disk swap and a home brewed big brake front kit with Wilwood calipers. I have a milling machine, so spindle mods and custom dog bone spacers are not a problem. The master cylinder will probably need to be replaced and a proportioning valve added depending on the piston bores of the calipers.
Well, that's it for now. I will be sure to document everything I do to the car, so make sure you subscribe.
