Im finally about to pull motor this Sunday since all thats needed is to unbolt motor mounts and then the bellhousing bolts to get my block out.
Since I have a version 1 ap with a pro tune on my stock turbo i don't want to do too much upgrading while I'm rebuilding because I don't want to have to retune it till I get a larger turbo and top feed conversion in the future.
The car is 2005 STI pro tuned for the current mods that consist of borla header, mad dad divorced catted DP, perrin twin tube exhaust two single muffler, Walbro fuel pump, ingen CAIC, ignition amp & a perrin FMIC.
The new block will be a MPS built block that has Wiseco pistons and K1 rods of course blueprinted and balanced.
Along with the typical maintenance parts that will be replaced I will be installing a perrin pre MAF turbo inlet tube, phenolic spacer along with just cleaning up the burrs and polishing anything thats on the intake and exhaust components.
I've been told that my ecu should be able to compensate for those simple mods with out a tune but my real questions are below.
If I just remove the butterflies and port match the TGVs and intake will that affect my tune? (I plan on going top feed conversion with composite TGV housing when I do a large turbo)
If I reverse the intake manifold and shorten the FMIC tubing will I need to retune for the smaller over all volume of the FMIC piping?
Probably won't do this but I have a friend that can weld and its tempting)
Any info would be appreciated and thanks in advance.
