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.

They make aluminum flywheel kits with puck clutches.



How strong are the 7AFE rods in all reality, what about if you cryo treated them? Strong enough to take about 250WHP reliably? If so I would be all for it. However with the cost of aftermarket rods I can buy a crank and rods, the block will be in for machining, and so will the head, the extra to have the deck and head machined down is minimal, and the pistons can be switched for engines and sizes with no additional cost.


All I am truly loseing is .2 liters and that will be made up for with the extra boost hopefully. This isn't a set in stone project either, I have considered going with aftermarket rods, or having the rods hardened, but from all the research there is no comprelling reason to not do it.




And for trd94 I can't find a seperate crankshaft posistion sensor other than the one in the distributor housing, and it is within specs. I am still waiting to get the other new coil to check. If that isn't it I will have to see about checking my ECU.
