Frequently Asked Questions

Start with a consult. Tell me your platform, your real goal, the fuel you want to run and how you actually drive the car, and I'll tell you honestly what it needs to get there — and what it doesn't. From there you get a real parts list and a real number before anything comes apart. You can book that conversation from the contact page or just call the shop; there's no charge and no pressure to walk out with the biggest build on the board.

Yes — both, and that's on purpose. A lot of shops pick a lane, Subaru only or German only, and every car that rolls in gets the same answer. I've spent years inside EJ and FA Subarus, K-series Hondas, 2JZ Toyotas, SR and VQ Nissans, rotaries, and the N54, EA888 and AMG side of the European market. JDM and Euro ask genuinely different questions, and knowing both is how I keep from forcing your car into the build that fits my comfort zone instead of your goal.

Usually, yes, and I'll be straight with you about it. If you've already bought quality parts that fit your goal, I'm happy to install and tune around them. Where I'll push back is on parts that are wrong for your target, mismatched to the rest of the build, or the kind of no-name hardware that fails and takes good parts with it. I warranty my labor and my tune, so if a part you supplied is the weak link, I'll tell you before we build on top of it rather than after it lets go.

It depends entirely on the platform, and the honest answer is a number, not a Stage label. Every engine has a ceiling where the stock pistons, rods or sleeves become the weak link, and a good build lives just under it or commits to the internals to go past it. I'll give you the real ceiling for your specific motor and fuel before you spend a dollar — sometimes that's great news and your stock block will happily do what you want, and sometimes it means a built motor is the only honest way to your target.

Both have their place, and the right call depends on how far your build has gone. A quality off-the-shelf or e-tune flash is a real, cost-effective step for a lightly modified car, and that's the ECU tuning side. Once you're stacking hardware, running E85, or chasing every safe bit of power, a custom dyno tune on the loaded dyno is how you get a calibration that's actually dialed to your car, your fuel and LA heat. I'll tell you which one your build genuinely needs instead of upselling the bigger one by default.

Yes, and it's one of the most common cars that rolls in. A tune that underdelivers is almost always a symptom of something underneath — a fuel system at its limit, a boost leak, a heat-soaked intake, a mechanical problem the last shop tuned around instead of fixing. I diagnose the cause before I touch the calibration. There's a whole breakdown of why this happens on the page on tunes that don't make power, and if that sounds like your car, bring it in and we'll find the real reason.

More than a phone quote can honestly promise, but never a mystery. "Call for pricing" isn't how I work — every service page on the site carries real Los Angeles price bands, from a few hundred dollars for a flash to five figures for a fully built motor. The right number for your car depends on the target, the platform and the parts, which is exactly what the consult and written quote are for. Browse the full service list to see the ranges, then we'll pin down yours.

A realistic window, given when I can see the car and the parts list. A flash or a bolt-on install can be a day or two; a turbo build runs a few days to a few weeks; a full engine build stretches longer because machine work and parts lead times stack up. Engine and fabrication work waits on machinists and parts more than on labor, so I'd rather give you an honest date I can hit than a fast one that slips a month. If something outside my control moves it, you'll know as soon as I do.

It can, if it's planned that way from the start — and I plan for it on street cars. The key is whether the parts you're adding carry a CARB Executive Order and whether the emissions equipment stays intact, because that's what a smog check and a referee actually look at. Some builds are street-legal, some are honestly track-only, and I'll tell you which side of that line your plan falls on before you buy.
