the engines are exactly the same i have done my home on alldata at school only difference between them is a 1 degree timing angle and compression ratio(exactly the same) and yes i do have the manifold gasgets downpipe. also the ecu runs the boost controller and will run up to 9-10 psi and this week will hope to shop around and find a manual boost controller(mechanical not electronic) which will let me run 15(don't know if it'll be reliable at that or not)the turbo will max out at 17 at full potential. also i've seen mx6 626 probe's of the same engine own honda's and most mitzu's(also my first car just moved 2000miles to here so aint goin nowhere yet)
