420A 0 boost

[Cfrakes]

So I have a 1999 eclipse RS with a 420a turbocharged motor that I just bought. The current engine is screwed so I'm throwing in a new one. My question is with putting it all back together is there a way to keep the turbo on the engine but run it at no boost without screwing with anything? I don't want to ruin a motor, and I honestly don't care about this one being turbocharged I just want it to run for a long time. Thanks

The harder you the push the engine the harder your turbo will work so just drive the car lightly and you wont create boost.

Depending on what waste gate setup you have, you can put a very low psi spring in it or adjust the actuator to a low setting if it's capable of adjustment.
Like already stated, keep your foot out of it and don't rev it out to keep the turbo from pushing too much air.

You probably should just buy a non turbo headers, put stock injectors on and stock ecu (if it has aftermarket ecu) you can get them fairly cheap and they're easy to install, I think if you're not going to run any boost, it's just meaningless to have a turbo setup, but if you really wanna keep it and run 0 boost, you can always disconnect the intake pipe so manifold won't get above atmosphere pressure, but I would just took all turbo stuff off and either sell it or keep it depending if you wanna add it later but if I were you, I'd at least would do a lot of research first, you just end up braking things since 420a is not really good platform for boosting in the first place

That was kind of my thought. I'll probably just remove it. The previous owner I just got this from definitely did not take care of this car so it's got work needing done to it, and that's why I got it for $300 so dealing without a turbo would be a lot less hassle. Where would you grab some stock headers ebay? Junkyard? Thanks.

I've run eBay "racing" headers on my 420a years and they cost like $70 shipped, also gives a bit better sound and couple horses

I do agree with the non turbo header and injecter theory.

Yea... we're going to miss those days. Try searching for those now. They don't exist anymore, in fact I can't even find the DC 4-2-1 ones anymore either. These are sad times for 420a header options, I wonder which parts are going next...
