7afe Turbo Options

[Cevax]

Well I didn't want to start this thread yet since I am still sourcing parts but I really need help getting parts since I am not sure what to buy. I have a 7afe now but i believe it has a rod knock and was told by a mechanic that to change the piston and rods the whole block has to be machined and will cost too much money, even though its only 350 dollars on parts or so for OEM pistons rods and rings he recommended me finding a new engine which I cannot find for less than 750 including shipping.

but if I buy piston and rods why wont they just drop right in?

I also have a 4age blue top head in my house that I got for the build before I found out my engine might be blown but if I have to buy a new engine its going to cost way to much to even begin the 7age conversion. My engine has a constant "knocking sound" coming from the cylinder head at around 1500 rpm it goes away at high rpm, It has 155k, abused but still runs strong. But during all this time looking for a motor (and saw a 7age with 115hp) personally started thinking that going with just the 7afte idea might more cost effective and since the 7a gets to peak torque so quick it should be more fun to drive( thoughts please), but anyway anybody with any experience on building a motor does it really have to be completely machined.

thanks

what do I do when the motor has no harness or ecu? just source it or would a stand alone ecu work

you stick your thumb in your butt, cause thats what happens when you dont do your research and buy a motor with no harness or ECU. you end up sitting there, with your thumb in your ass saying "why did i BUY THIS?!?!"
you'll need to at least source a harness (possibly tweek could make you one?) and the ecu (or engine management of your choice) and then sourcing whatever sensors ect that didnt come with the package as well.
it really pays to do your research BEFORE you buy anything, there are TONS of threads on this board, that ALWAYS say make sure you get a complete setup with ANY motor you buy thats not the original motor in your car. you ALWAYS need the harness, ecu, any and all sensors from the engine and engine bay ect.
its just simple common sense.
