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.

When I say cheap I mean the engine kit with interchangeable pistons is around $875.00 for pistons, rings, full gasket set, main, and rod bearings, oil pump overhaul kit, and a few other odds and ends.


Turbo Kit was $1700ish without a intercooler, I may not run one if I can get the charge air cooled with a water injection kit. Dunno what that will do to charge temps though, need to do more research.

The block work is really good on price as we use the company alot $15.00 per hole to bore and put on a basic finish, $100.00 to balance everyting. We have used the company that does the thermal coatings to do spray wear coatings, TCC and Titaniumnitride, but the ceramic coatings can be had for $45 per piston, and $30 per exhaust valve top and some stem. I work as a parts manager for a Ag company, so alot of the fill in parts can be had for cost, and tools as well as a large shop.


Has anyone here used 4GZE parts in a 7AFE yet? The specs seem to line out minus some possible grinding in the block for counterweight clearance. From what I have found on the 4GZE they were designed to take quite a bit of punisment, and the only inharent differences are the longer connecting rod, and a slightly longer stroke.
