1.8 from circa 1990 corolla.. 4 Series?

RE: my new KE70.. i'm looking for an alternative to a 20v or 16v 1.6 and was thinking the regular 1.8 used in corollas from circa 1990
is the 1.8 from these cars a 4 series motor(i.e 4AGE etc)
if so i cant imagine them requiring much more modification than say a 20v (or 16v for that matter) but with an additional 200cc and a much wider parts base.
The reason i ask is that these engines are not considered performance engines and wont have been thrashed plus they dont have the additional price loading that is inherent with 20v ("its 100kW bro!" "it must be worth 400 bucks more than what i bought it for and i've thrashed it because i thought it was a performance engine.." etc)
cheers

the 7AFE is a A series engine.
The 20v is quoted of making 160 or so horsepower or about 115kW..

7A would be an interestign swap.. same issues as any other 4AG, but with more capacity, ie more torque.. look for info about 4AG head onto 7A block.. has been done a few times, and would be interesting.

Don't bother with the 7A-FE unless you're going to put the 4A-GE head on it.
It doesn't have a wider parts base coz there isn't anything you can do to it & I've never heard of a 7A-GE coming from Toyota anywhere.
There is a reason for the extra cost.

then again, a 7AFE in a 950kg or so KE70 would still go pretty darn well... it won't have top end like a 4AG, but it will be very 'nippy'
go on.. be different

top end is probably not all that important as it's going to be drifted 90% of the time..
does anybody know of the bolt in compatibility of this engine..?
there will be no aircon and no power steering....... or interior
can somebody please help with info about this engine.. i dont care about the performance side of things.. i can deal with that later..
i'm thinking about things such as how much harder it will be to put in than a 4AGE or similar, what will need to be modified (i.e water outlets, ignition system.. i.e dizzy (???) will the mods that address engine bay fit issues be similar to a 4 series engine?
even if i am given educated guesses they will be much appreciated..
i will be looking to buy the engine in exactly a month (month = 2 fortnightly pay packets) so if i can start looking now i can prolly find a decent one by then..
what ancillaries will i need to keep?
P.s thanks for everybodies help but this is not speculation. i will be buying an engine in a month and am trying to get as much information as possible so i can make an informed decision at the time of purchase.
cheers

We stuck a crapfire 2.0l from a corona in one (bog stock), very tidy shell, slighty lowered it, RA40 brakes, Kmac kits. Made a fun thrash around compared to the 'K' series it had. When I sold it.. Easy as too... the guy had only test driven ones with the 'K' engines and couldn't belive how much fun it was! Still regret selling it and not putting a 22RE 2.4L I had sitting around at the time.... would of been a burn out King with that torque

what would i expect to pay for one of these engines? when did they cease production? this is another point on which these engines compare favourably.. i figure that you could pick up a newer engine for the same price (or cheaper )

expect to pay anyway between $800-1500 depending on condition| Quote: |
A few treads on here have raised questions about the strength of the 7AFE bottom end.
|
It's not the crank, it's the rods! A few 10 thousand km's in rally's and that's all I have ever broken yet! Rectified that and still going strong after a more few 10 thousand. That's a myth about the crank , the rods are the crap design.

Between the 4A and 7A blocks, some of the bolt holes are different, but the one's where the RWD engine mounts bolt up, I couldn't tell you. Dizzy is on the back of the head, along with the thermostat housing and heater hoses, so a bit of mucking around is need here to clear the firewall. Dizzy you have two choices, you could run a 20V crank angle, (dizzy without cap)which does fit with a small amount of filing, and wasted spark setup ie muit-coils like GZE...or cut the firewall to suit. The thermo housing etc... well, that's anyone's guess.

how difficult was this conversion.. i dont want the shitty satrfire though.. at this stage any engine other than stock will be a bonus.. the thing is super light so crazy power isnt crucial..
maybe i'm asking the wrong questions.. are there any other engines out there that have the same bolt up compatibility as a 4A block? i have no issues at all going with the 4A and it has been my plan all along.. i just figured an extra 200cc would be nice and if it was as easy a fit then it would be well worth it..
but there is so much more knowledge of the 4A engines with the added bonus of people having done this conversion before (i.e PMP80Y and others )
keep the feedback coming

All we had to do was move the engine mounts forward by an inch, everything else bolted up
