thanks for the good info maxlap21 not only do you benifit from the slightly reduced inlet air temp you also benifit from the reduced restriction of the larger air filter.the less work the compressor has to do to to compress the air the less it is heated and the more cfm you get at the same psi vs.tem rise

I know this thread is old but this is why there is this section for you to read and find out what others did to fix their TGP's. The bolts in question are metric ,they are 8mm x 1.25mm thread pitch x 25mm long minium thread grade of 8.8 . do not use any lesser grare as they will not stand up to the heat and repeated stress of heating and cooling. cadnium plated bolts can be found at Lowes or Homedepot or go to the junkyard and pull them off almost any latemodel car just take a sample bolt with you for comparrison.

what is the advertised"factory" compression ratio of the 3.1 turbo. what kind of static comp.should I expect to see.

thanks for the input.can anyone give me info on the 28gtrs turbo.where to get one.what kind of mods to make it work
