Question about a Larger Fuel Pump

[Morel]

Would it have any benefits/problems installing a larger fuel pump in my 420a?

Planning on doing the slow step by step process of the Turbo upgrade

There should be no problem with installing it, but there will also be no benefits with installing it until you turbo or you use nitrous. I had mine installed for weeks before I went turbo and I didn't see a change in gas mileage. It only pumps more gas only if you need the extra gas. For example with the FMU 12:1 For one pound of boost = 12 PSI of extra fuel. 0PSI of boost = 0PSI of extra fuel. Good luck trust me you'll enjoy it once you go turbo!
thanks

Ok cool!

Hey, does anyone know if you have to take the engine out to put forged pistons in?
Also, can you use any intercooler? or does it have to be DSM specific?
And what is the point of no return when installing a turbo peice by peice?

And yes. I searched!


Thanks!

1. Do you have to take the engine out to put forged internals in? It would make you life a lot better if you take it out. I wish I did when I changed my head gasket.
2. Yeah, you can use any intercooler you want as long as you can make the piping FMIC, SMIC. It doesn't matter they all do the same purpose cool the intake temp of the air.
3. That all depends on how you hook your stuff up. The fuel system you can go back easy. The oil system will be hard for me because I had my brass nipple braized into my oil pan. You can also buy a new oil pan though. My factory downpipe was cut to pieces by the muffler shop so if I want to go back I can very easily but it will cost me money. i.e. in my example I would have to buy a new oil pan or have the old one fixed, and a new downpipe.
Bottom line make sure you have a lot of money save up at least 800 before you start,it makes it easier. but you will really like the results of it though.
