The "I heard this, I head that" BS from some moron forum guru gets old. I've seen dyno sheets from turbo and nitrous SOHCs and they have more HP than a DOHC does, and quite a bit more torque. What have you seen, besdies the hearsay from the cookie cuter bandwagoneers, g unit? | ok... and how much money is it going to be in comparison to both. Yes it can be done, but a turbocharged DOHC... im sure is way better then a turbo SOHC. and by alot. so forget the "i heard bull****", I KNOW a sohc is always going to be slower then a dohc with the same amount of money you put in both.
tacojoethethird, dont waste your money with a sohc. spend the 1500 on a new head and simple bolt ons. if you want better power then turbocharge a dohc.

For $1500 he could put a 75 shot on his current car with some mods and walk a bolt-on DOHC.
Taco, what kind of horsepower do you want from your car, how fast do you want it to be? If you're just wanting 50 or 60 more hp you could keep your current engine setup. But if you're thiking you're going to get 400-500 hp out of it, you would be better off building something else. | |

I love these kind of threads.
If you really wanna turbo you car, I would only swap the head out and you would actually have a prime setup if you have good compression in you stock engine. That way you would have the flow of the dohc head (the major limiting factor in the sohc is the head) and you would have a good compression to run boost on (the sohc has 8.5:1 pistons, dohc 9.5:1) and you would have the desirable transmission for running boost.
BUT from the way you worded your first post, you have a lot to learn yet and need to do alot of research if you don't know what parts to get. Even if somebody told you what to buy, you still need to know how to hook everything up and get it tuned properly or you will blow up your engine.
Nitrous can be fun, and is fun but you must be smart when running it or you will wreck stuff also. I always make sure to change my oil often and make sure my plugs, wires, and coils are in great working conditiong. | |

better yet, does it look like ima waste my time arguing with you that its a waste of money to turbo a sohc, when you can put that money in a dohc.

You know, it seems like the restriction on the SOHC with turboing is airflow. If only it could flow better. Maybe... 2 more valves per cylinder! But how could that be done?

I'm getting ideas though. If I wouldn't have asked then I would've wasted money on a turbo and not a head, or something like that. I start working in 2 days and until then I don't have enough money to start the project anyway, and it'll probably be more of a summer project. Nevertheless, I appriciate your advice and everyone's help. | |

Turbo on a sohc is a no no! do a motor swap you will be much happier.  | |
