4AGE 16v Bigport TVIS from a 1988 MR2 AW11. Sent it out to Chris at Maximum Machine Works out in Longwood to have him do a 5-Angle valve job, a slight port and polish, deck both block and head, install the HKS titanium valve springs, arp head studs and exhaust bolts, balance the bottom end and shot peen the internals. Currently staying with stock pistons and rods ( I have a 1ZZ in my backyard might look more into the 9AGE idea.) plan is boost when I find a 70's rolla to put the 4a into. But that might happen early more to come on that.
