Hi guys, I really need some help! I'm in route to remove my bi-turbo setup, all the vacuum lines, all engine harness, OEM ECU, entire A/C system, power steering, air pump and ABS system... I'll do this for a clean in my engine bay and an update in technology... I'll put an Fueltech system to engine management etc... engine is original, good compression and 90k kilometers originals.... no leaking, no overheat and all life in a 150:1 premix + OMP working together.... Now is the point... what size of the turbo is good for my engine? I like the "shoot" in low to mid rpm range but all the upgrades I've seen, the "shoot' are in high rpm range and the "turbo lag" is too high... a friend of mine said to buy a MasterPower turbo R-596 (compressor 59/turbine 64.5) but it's too big for an original engine no? What a good turbo size for my car? Thaks for all !

 

Do some reading in the single turbo forum. The new Borg Warner EFR 8374 is amazing for response and power -

Easily do 450hp with a fat power band.
