I am getting ready to turbo my 1.8L engine. And I already know that you can't turbo a 914. But, what i would like to know is what are good cars to get turbo's off of?
I am looking for a small turbo that will spool quickly. Looking to run about 7 to 10 pounds of boost. What turbo'd cars will give me a good turbo to use? I have been looking for ones on ebay, but don't really want to buy one there. I don't mind buying a used one, so going to the junkyard and getting one is definitely an option. Which turbo? |

Ive been looking at a lot of type 1's with turbos and have been reading what those guys are running on their manx's and bugs. Theres one that is a complete backyard engineering and works pretty well. I have been looking at that setup because it is very basic, and pretty simple to follow. He listed everything that he is using with the turbo, which is helpful. Reading up on that thread, i learned what i needed to about to run approx. for timing retard. This is a type 1 engine, so not everything will transfer perfectly, but by following his setup, i can at least understand what's going on. The major difference between his turbo setup and mine would be the tuning settings would probably be different.
I still have a question that i have not gotten a good answer for. Ive read that with a turbo, the fuel pressure must raise with boost. However, it seems like if you run low boost you don't need this, but higher boost numbers need to have the fuel pressure raise with boost. My question is, is that after reading through the backyard engineering thread the guy uses a Holley Red fuel pump, that only puts out 7psi. The guy says he runs 15 pounds of boost on his type 1 motor. 15 pounds of boost is way more than 7psi. Shouldn't it be that if you run 15 pounds of boost you need 15 psi from the fuel pump? So if i run 10 pounds of boost, when the turbo reaches full boost my fuel pump will be putting out 10psi? thats what i need answered. here is the thread Backyard Engineering Turbo |
