Gotcha! My ploy worked to get you to read my babble. Although the question is indeed valid. I wanted to ask my readers this; If you were to buy or put together a car to enjoy on the street and the occasional track day, what car would it be, and would you turbo or go the au naturale way??
Of course picking one or the other isn’t exactly that simple. Ignoring the outrageous pictures above, there are obviously questions that need to be answered before a decision is made.
- Budget/Cost – Upgrading or putting together a basic turbo motor is initially going to cost more than the N/A build. With all the external additions like the manifold, turbo, downpipe, and associated equipment, there is definitely more cost involved. With the naturally aspirated motor only needing basic bolt-ons, the cost of entry is substantially less. Of course, both builds will require more dinero as power goals gain altitude.
- Power – Depending on the motor you decide to go with, it could almost go either way. Of course turbo motors have a greater potential for producing horsepower while the N/A motor will require more intricate (nee expensive) work to create noticeable gains. Unless you decide to use Nitrous Oxide, but that’s a whole ‘nother beast that should probably be exempted from this topic.
- Reliability – No matter what people say about turbo’s being time bombs for motors, it’s all about the tuning. That goes for both the N/A and turbo engines. I personally know of a naturally aspirated, high compression, stock block K20Z3 that has been turbo’d. It makes 440 horses to the wheels! Did I mention it’s a stock block?? Yeah, so if you want a motor that will survive those shitty days in traffic or the grueling laps at the track, you better make sure that whatever setup you decide to go with is operating properly.
So what’s it gonna be?? What car and what setup would you go for??
