Don't bother with balancing and any other procedures. You won't gain anything with the 7A-FE. The engine is reliable as it is. Just get the tuning right. Don't go past 15 PSI with a turbo bigger than a T3/TO4B. I had bad experiences with replacement pistons. They just don't hold the power as well as OEM ones. You're better off with original Toyota pistons. Don't skimp on the pistons. Rods are fine. I abused mine and they never gave up. Don't lighten that flywheel. Leave it as it is. Don't bother with all the things that are done to other engines. This engine doesn't benefit from that. Use good oil, good tuning, and good cooling. You do that and the engine will treat you right. Keep the turbo system as simple as possible. My car was faster with less fancy stuff. It felt faster with an A'PEXi S-AFC and small diameter intercooler piping. The more I upgraded, the slower it got. Oh, use an oil restrictor on the oil line. This engine will damage your turbo oil seals from the ridiculously high oil pressure.

i got forged pistons as i was told that the comration ratio or sumin on ome parts will mess up engine.
also conrods are weak so i got pauter ones, which am told are the best. i just want to skim the head so high preformance copper gasket can go on.
here is a list of work which is gona be done.
the turbo is from http://www.prostreetonline.com/pnsku/tc25b1x.asp and was fitted to a celica and i bought it from a guy as he sold his celica standard, he did give me a oilfilter relocation kit as the coroler is a bit dif.
the engines intrnals was from http://www.importperformanceparts.net/impo...pek-toyota.html i also have the conrods from them and toga hv oil pump which i dont av a clue in what it dose.i got a stage 3 6 puk clucth kit.
i dont understand y this will make it slower, iv been reseachin this for a long time i hope i havent wasted time n money.
what is a oil restrictor on the oil line???
