talon boost

[shming123]

How good are eagle talon engines at holding up to turbo upgrades, cams, etc..engine mods... how many reliable psi's and hp is it capable of handling?

The 4G63T takes very well to upgrades, if done in the proper sequence.

There is a very good tuning guide on this website.

As far as reliable boost, I run 18psi on 93 octane on the street, 26psi on 116octane at the track, on an engine with 145,000 miles. No reliability problems with the engine yet. This level of boost/power is relativley common among modded DSM's.

The 6-bolt engines are completely reliable to about 450HP (and beyond), 7-bolts should hold 400 crank HP.

Of course these are gross generalizations, as always, your mileage mayvary.
