I have heard rumors of putting a 7afe crank and pistons in the 4agze block...this was my first thought of a place to start my research. All i want to know is if its a possiblility... it would be wonderful to get the 1.8 liters out of a 1.6!

wrong section there buddy...try engine section
wat your looking for is called a 7agze, or 7agte trying the search button

your thinkinig about the 5age, pretty much a stroked 4age.

please use the search button.

5age... are we randomly making up engine codes?

I think were just throwing together motor codes heh?

It is possible to stroke out the gze, I saw a HKS crank for stroking it out to 1.8 liters on ebay this past week, it sold for about 750 I believe

-FAQ

we didn't say you couldn't stroke one...but what we did say is no throwing out random motor codes...

a stroked 4agze is just called a 1.8l 4agze stroker..not a 5agze..or a 5age..

IF you want more info on the 5age go to club4ag.com the 7age is there also

The 5A-GE

Once a very popular mechanical tuning approach to the 4A-GE engine, the 5A-GE engines proved that more torque could be had in the otherwise peaky nature of the 4A-GE. It wasn’t without demerits but the 5A-GE did fare reasonably well in the enthusiast market. HKS makes a range of internal components to suit your needs and 5A-GE was one of them. The 11.6 compression kit comprised of longer stroke crank, 81.5mm pistons and various bearings, rings and fastener sets is the most aggressive. They are designed to be built using the 4A-GE and proved to be very high quality in design and materials. However, the 5A-GE isn’t without pitfalls so we’ll discuss a few here in detail.

The first thing we must note in the 5A conversions is the fact that the block needs to be modified somewhat to make room for the longer stroke crankshaft. The 5A-GE kit uses this long crank stroke to make approximately 1700cc displacement but slapping this crankshaft into the 4A block; one will immediately discover that it won’t spin without hitting something. No, it’s not a defective unit… So we modify the block by grinding away the inside of the crank case…. by placing the crank and working away where it hits. The clearance here should be no less then 1mm so you can avoid damage when there’s engine failure elsewhere. Next, attach connecting rods and repeat procedure. One note here…never grind the rod or crank as this will upset the balance and strength of the moving pieces…unless you are doing it for the purpose of getting better balance.

please dont call it the 5age.

someone may thing you're putting a G head on a 5afe which is the 1.5L from the paseo/tercel.

the 7age wasnt made from the factory either what would you like us to call it ?? all the "5AGE" is is a 4age that has been stroked out to 1.8L or you can just bolt the 7afe block to a 4ag head and you have close to the same thing so either way its a 4age head with more displacement .2 liters more

then call it a 7age. the 5afe is already a valid toyota motor designation, calling a stroked 4age a 5age is very very confusing. hell just call it what it is, a stroked 4age!

this is pointless all i was doing was pointing out that the term or code 5age was being used over on club4ag the home of the 4age motor etc anyways this guy i think is looking for info on the 7afe with the 4age head on it i think

They have been calling it that for a while.
Don't get mad at nik he didn't name it HKS did.
5age 7age

I have an ST. Would it be better for me to do just a 4agze swap or put the 4a heads on my car. Which would give more power?

>


A 3s swap is about the same or less than a good 7agte $$ wise.
Parts availability is better for a 3s swap. 3sgte is proven very
reliable. 7agte is an infant. 4age proven also. Buy Coomers Car
cheaper than all above.

the comment wasnt directed at him persay, its just a poor term.

lol. Thanks for the info. I think I will do a 4agze right now and FURTHER down the road get the 3s.

this is very true when i was researching there is very little info out there on the 7agte there are only 2 of us on this site who run the 7agte and only a had full running the 7age on the club4ag site i beleive im the only one running a fully built one to my knowledge but depending on what you build up you can build one for the same price as a swap but thats my opion and its not easy
