turboing my 420a

[scottypimppin]

ok i just rebuilt my head and did my timing belt water pump, cosmetic head gasket arp head suds, i was just wondering would i be ok turboing my car and how much psi would be safe?

I wouldn't boost past 8 psi until you redo the bottom end...

depends on the octane rating. if you run e85 you may be able to run more even without an intercooler.

you can easily destroy your motor if you are not careful.

have fun!

Please do not listen to these people who dont have a 420a. If everything engine wise is running okay, you can run up to 12psi if you tune it correctly but most people like to keep it around 7-8psi on the stock bottom end. You will not need bigger injectors, afc, or e85. You will, however, need a 255hp fuel pump and at least a 12:1 fmu with stock injectors if you want 8psi or less.

listen to this guy. Most 420a's can run 8-10 safely with no issues just make sure you do a compression test and research before you dive in treadstone and hahn have great turbo kits for our cars.

This is a great starting point...I did the same thing as tegster, pieced it all together over a course of about 6 months. Boy was I happy when I started putting it all together! You can easily keep the cost under $1000 if you buy quality used parts. Start on craigslist and ebay- Most turbo parts are universal for the 420a.

I suggest starting with the fuel system. This can be done long before the turbo, so try a walbro 255 fuel pump to start. It's a fun little project. Then decide if you want to run a FMU, SFMU, or maybe something better. We're all here to help!
