The Engine Behold, the test engine: a well-used B16A originally purchased from a local Japanese engine distributor. A Little Tuning Goes A Long Way The question seems simple enough: What's a turbocharged Honda engine's most important difference. Remaining true to form, the idea to use aftermarket head studs was tossed aside and, instead, the factory head bolts that had been through countless torque cycles were used, along with a factory head gasket. All of them had 1st gen B16's. As for the B18B. They ring a head gasket that effectively drops compression to 9. Not sure if their shop is set up yet, but go on the forced induction forum here and start reading if you want to know what you are doing kinda when it comes time to put it all together. Solo you reach that range, the stock rods, and the cylinder sleeves become an issue. A B16A can last just as long as ANY other motor, being driven daily well above 9psi. Naturally, this drop in compression reduces the power output in normally aspirated trim but allows for sincere boost levels, especially on the street.
Sooner or later, they're gonna give. Probably sooner than later. I've seen them run strong for years Whatcha smokin'? It's not common knowledge that the B16A is a bad motor to turbo. It is common knowledge that the B16A is the best Honda motor to turbocharge. It has a near perfect rod:stroke ratio, and the internals are extremely strong, and can withstand years of punishment, make more than 350hp stock, and can kick the crap out of all other Honda motors. You know what makes you think that it is a bad motor? I know the answer... If you tune a motor wrong, it will die... Originally posted by MatT3T4 Whatcha smokin'?

Just said it won't last long after 9psi. Have you ever turbocharged a B16A, sir? Correct me if I am wrong. I ran a turbocharged B16A for 3 years. I built it after an injector o-ring broke, which was installer error... I ran the car for about 20 months, daily driven, between 10-15psi. A B16A can last just as long as ANY other motor, being driven daily well above 9psi. As I said before, you are being misled by improper tuning. If a shop told you, or someone else that the B16A blew because it was boosted more than 9psi, I would be willing to bet that, that was the shop that tuned the motor, and they fucked it up, and that is their cover. The B16A can last for years above 9psi... Please don't spread false rumors about this motor to prospective enthusiasts. The B16A is the best Honda motor to turbocharge, bar none. I don't mean to be jumpy against you, I just want you to understand that tuning is KEY, and that the B16A motor can last eons above and beyong 9psi. Well, it's obvious you have more experience than me on the B16. I've been going from what I've been told. But, I just can learn from my own personal experiences. Most everyone I've talked to on this post will not go above 9psi before they upgrade the stock internals. That's what I've heard from a lot of people. Just to verify, my 99 Civic EX SOHC IS a B16, right? I have tons upon tons of experience with the B16A, along with other Honda motors. Your motor is not a B16A, yours is a D16 something. The B16A first appeared in Japan in 1988 or 1989, in the EF chassis CRX's and Civic's. The B16A is the DOHC VTEC motor. It made its way to America in the DelSol DOHC VTEC models, and in the 99-00 Civic Si. You have a D-series SOHC motor. The SOHC motors can handle some boost, contrary to what some believe. I used to have a D16Z6 1995 Civic EX SOHC VTEC with the GReddy kit on it. Trust me man, Honda motors aren't weak... I never thought they were weak, but I suppose I've been mislead by the local shops about how much boost is safe. I think it would be very informative if you would make your own post about your experiences on boost levels according to the different engine types. Thanks for your info. You've helped me a lot. If more posters would do as you have constructive criticism , much more information would be absorbed. With the D-series motors, you can make around 230-250hp with the stock internals. Once you reach that range, the stock rods, and the cylinder sleeves become an issue. If you have a good fuel and ignition setup, and your a:f ratio is properly dialed in, then you can make those 14. I blew my SOHC motor doing 145mph on 11psi or 12psi, for a few miles... I spun a rod bearing. You can make 13 second passes on D-series motors with stock internals. As for the B18B... Now, the B18B has the low compression which allows for a larger window of error when tuning... It is a very strong motor, and with fuel and ignition upgrades, along with great tuning, I have seen people making 380hp 20psi. Check out my website, www. You will see a huge page that I made regarding turbocharging Hondas. The key to making a good, powerful, reliable Honda motor is tuning. You need ample fuel and ignition, and you make them work together with the tuning. Once you get your air:fuel ratio correct, and the motor dialed in, your have properly tuned your car, and the only thing you have to worry about is prolonged boost. By that, I mean... Get on 15psi, smoke the Porsche, and then go back to your normal, unassuming 9psi... Thanks for the info Mat... I havent directly heard that the b18b series was good for boosting, but from what I have researched I figured it was due to the low CR and strokeXbore. I will probobly give you a shout when I get ready to build it. I am putting my ignition on this weekend... Exhaust and fuel are next. Ummm, I don't really know any sites with detailed instructions man, sorry. I have looked before also, but they're hard to come by. They market a head gasket that effectively drops compression to 9.
