Conversion Options

[Steevo]

Anyone have any sugestions. My plan is as follows for my poor little 7AFE it is blowing oil out everwhere and the valve seals are leaking.



Get some 4GZE rods, and crank (used). A set of oversize pistons, have this block bored to the 82.5mm with 9.1:1 comp pistons. Turbo kit it, they have garret kits for the 7AFE that fit corrolas, and a ebay intercooler. SAFC2 port the head and intake some. 2" cat back exhaust, aftermarket cat.



I have found cheap engine kits, I know a company that can do thermal coatings, for valves and the pistons. A machine shop around here will do my boring and piston-crank-rod balancing. A toyota dealer has the tool to do the valve shimming, and will rent it out. And a friend has a exhaust shop, and can either do crush bends or will have mandrell bent pieces made, and weld them up, stainless.



So far I have come up with about $3,400.00 ish for everything minus the crank, and rods. But I have no idea where to get them, or if they truly will work. Talking with another gear head on the west coast he used the same setup to get better rods for cheaper than aftermarket, and a better TDC duration for close timing under boost.


Any help is very much appriciated.

I bolded some things that stuck out as issues to me.

intercooler..ur gonna want a quality one. dont cheap on an ebay special.
2" exaust is to small IMHO id go with at least 2.5" on any turbo car.
the word CHEAP......its the killer to ANY turbo project. ull just spend more money in the long run repairing what keeps breaking.

pistons will clost quite alot, ive seen after market pistons go for $2k for a set of 4...id suggest looking into the piston and 4agze prices first b4 going whole hog on this one.

GL tho, i really wanna see someone build up a 7a with 4agze parts.
