hmm i'll vouch for the not being able to run above 10psi...well on higher mileage fs03 engines anyways...out of the 4 people and I that turboed our cars around the same time all of them popped within 2K miles when uping the boost to 10+psi...now at 8psi mine ran forever, never had blowby never had hesitation, never had any problems period...well except overheating but that was a totally unrelated issue...now please keep in mind this statement only applies to fs03 series engines with 90+k in the 93-96mx6/probe cars. Also the turbos were for the most part t3/t4 which is significantly larger and flows tons more air @10psi than wussy t25s and 14bs, which seem to be the most prevalent turbo for custom projects...moving on..yeah Id def do an mx3 project...half the weight and the same hp engine....turboed KLZE in an mx3...drool watch out sti....I know my friend with a klze swap and turbo at 6psi put little over 250whp and ran the quarter in 13.4ish..its been awhile so I cant remember the exact time, but I remember my jaw dropping and my car drooling....
