You don't need to stroke it or add forged pistons to get 300 HP. You will need some sort of engine management, I good rebuild of the engine, hybrid turbo with intercooler, and a good exhaust system. That should get you to your goal.

 

can i go and drive your car around?
mite be some fun, haha j/k

goodluck icice

 

If cost is a issue don't take apart the engine, maybe only to replace the headgasket they are prone to breakage. If everything looks good when you take off the head swap engines. Invest in a good standalone fuel computer and everything Lockjaw said. Keep it easy if you don't want to spend big money forget the Z31 ECU.

 

wassup bro...I see you scored your self a turbo motor! woohoo Now the fun starts Everyone above have really good advice. But yes, I would spend the money on getting the motor rebuild....I wouldn't even hesitate to do it especially with a motor that has two hundered thousand on the ticker. As for stroking the motor, there is a guy with a yellow older Z (can't remember year) that has a turbo charged stroked motor. He's doing well with the set up but I've found that most Z'ers will tell you that storking a turbo motor is a no no. I know I've read about this on Zcar.com but I would advice you to search their archives...you'll find that this is a topic that has been thrown around. Forged pistons are nice but unless your going ***** out I would reserve that as a future mod. The stock internals handle boost very well and like Lockjaw said, it's all about the engine management (not to mention, forged pistons are expensive). Look into Ford Mustang SVO injectors with the brown tops...I think they are 35lb injectors. Coupled with a rising rate fuel pressure regulator and a high flow fuel pump, you will be able to fight off the dreaded pinging. Vinh, with the yellow Bruce Lee 280zxt has had good luck with installing a 7th injector that's controlled by a pressure switch. I will be doing this just to be sure I don't get pinging at 18psi. Also, don't skimp out on the head gasket...spend the money on the KHS 1mm metal head gasket. What kind of turbo are you planning on upgrading with? I would imagine your going with the T3/T4 combo. I've been thinking about going T4 with nitrous...only time will tell. Anyway, keep us posted on this swap and take lots of pics...I don't remember anyone documenting this swap on a 280zx. Good luck

 

There is a local guy here in Orlando that has a 260z 3.1 stroked with a T40E turbo, the car does 12's in the quarter mile. Whats really cool is this is his daily driver, Yup drives it all the time so a turbo stroked engine can be done! and used as a daily driver, Now this didn't come cheap, and no way it can be done for $1500. It is funny when ricers pull up to his car though, no fancy paint, plain white but when he hammers it wow!

 

LOL... If you are going to be doing some racing on that engine, you'll be doing it more than once,lol. But seriouslly if you upgrade the fuel managment you def. want to upgrade the ignition. You can have all the fuel and air you could dream of, but if you dont have that spark it aint worth a ****.Your 300z comp. swap idea is cool...but, I would not do it. You can get an aftermarket system for just a bit more than you could get the 300's sys. and get it upgraded. If you want to build a good car, and have it fast and dependable... BY FROM A RESPECTED COMPANY! But be aware----If you race you will break something. Been doing it for to long for anyone to tell me different. Well have a good one.

ps. good luck with your Z.
