You have to add in the cost of all the stuff you have to swap with the SS housing. Then there are smog issues for some states.

Only for Socialists Republic of California though :D

tell me about it. LOL other states have smog, too, but CA is THE WORST.

i got mine (ss green, 02 housing, tial mvs, pipe for the tial, oil lines) for half the price of a bb red. It is JB but again, it wouldn't cost more than $400-500 more if it was bb. The price difference is huge and their durability is supposed to be better. Or i am missing something and made a poor choice...

No wrong choices, if you are happy. {thumbup}.

My question was not a rhetorical one. I will install it next month, so i really try to understand how this thing with the fp turbos goes. Is actually an ss green equivalent to an mhi red? and if it is, why people don't go that way since it costs much less (complete ss kit to be installed) and is not prone to housing cracks.

Similar but not the same. MHI will hit a lot harder than SS as far as the torque. It come in very early when compare to the SS. Torque help move the car so the MHI has an big avantage in that departement. The SS flow very well up top (RPM) meaning it pick up speed easy once in the powerband. So now depending of what you like to do with your Evo, you choose a turbo that will suit you. If I was to autocross MHI turbo hand down the spool is there and it low end power. quarter miles the SS should shine especially the bb. It all depend of what you want

i believe what you are posting is a comparison between mhi and ss in the same turbo. Please read my post again. I am trying to figure the differences and similarities between ss green and mhi red.

My understanding is that JB and BB spools up almost the same. The difference is in between shifts where BB will hold shaft RPMs better so turbo doesn't have to spool up as much. BB will need less oil since you're lubing the BB but JB needs more oil since the turbo shaft spins on this thin layer of oil. JB can easily be rebuilt cheaply, but the BB cartidge will cost you $1k to replace. Personally, I'd stick with JB because, how do we know if BB is in good condition after engine failure? So do we always replace the $1k BB cartridge when rebuilding after engine failure to be safe (like what we do for oil cooler)?

My gut tells me lag will be similar between the two, but the Red will give you better mid range due to higher volume and less heat at same boost. Then on top, the Red will push hotter air since there will be higher backpressure on exhaust side at the cost of making more power than the SS Green. Would be cool if someone tested these two turbos already.

I got a lead on a FP green MHI with the antisurge 'FAP' housing for $800 + shipping, might snag that, only 1k miles on it.

But on the other hand MHI red....

They are great turbos. If I could over my fear, if I'd probably try another LOL.
$800 is a steal. Not sure I could pass it up.

be careful. If it is too good to be true, you know the answer. I think there were many versions if Green. I recall the super early versions not being very good. Do you know if the FAP was added on later while the internal wheels are the original design? Have someone verify that it's a newer version of Green before you buy it. How many blades are on compressor wheel? 5 or 7?

Well I had the BBK which is almost similar to the FP green. Now I have SS FP Red to different beast. MHI give you torque at low RPM (twin scroll) and spool faster and the SS torque come in later and flow better at high rpm. That is my personnal experience

I know the person who originally rebuilt that turbo and he was my referral, I was originally gonna get a rebuilt green or red from the same person, but he connected us

But yah I hear ya on that lol
