update 3/11/2024 I made this video just ranting about the engine years and years ago. Don't listen to any of my facts because I don't know anything I am talking about.
Back in 2009 my friend ask me to drive his car. A 1990 toyota twincam GTi AE92 that originally came with 4age smallport 16v. Before riding it i have expectation it will be low torque and high rpms, but while i started run it, i didnt expect the instant torque, i said to my friend what you have down to this car, he only laugh and order me to keep push the pedal, and i run it and it runs look like a b18 non vtec honda. After riding for half hour, we stop at his garage and he explain that he use 7afe block with 4age head. He said the block completely stock and head only port n polished. It should be came from factory like this
It's so hard to do bro . I have one half way and every time I think im getting close there is another issue. 2 years now and I have friends who are engineer's. You need both engine's because you will need parts from both plus a ton of shit of everything else lol. Have fun
I have a 93 DX Corolla with the 7AFE engine and I’m looking for a aftermarket distributor that’s reliable. Do you or anyone know where to buy a distributor that’s under $200.00 that’s doesn’t fail in six months?
7age is not inexpensive and a nightmare to make. It is definitely not a bolt on and go application. You have to go custom on a lot of parts as well a good bit of machining. The trd head gasket for one, the oil drain holes don't match up with the 7afe block. The deck height difference on engine block means you need a longer timing belt and a custom crank gear. The list goes on and on. Not simple, unless you have lot of money and time I would personally just keep the 7afe and modify the combustion chamber plus port and polish the head. Maybe use 4afe pistons because they have less dish. The main benefit with 4age is because the cams are driven separately on the belt whereas 7afe head the intake and exhaust cam are geared together, this limits n/a tuning a lot. Another big one of course is after market support.
realistic 4age n/a build can easily 220 hp, of course 7age will see a lot more power especially above 9,000rpm but the cost might not be worth it, you're looking at spending at least a 1000 bucks on this set up. Not a great engine for a daily driver.
I mean, how would one spend only $700 on the build, considering ecu management? Also concerning power handling, we all know the answer to that. Honda is the most superior for 4 cylinder power.
