7agte HELP, change the title still a collection 7age Options

[nik]

Well there is a lot of good info on here and I just want it in one spot i know kwanza and others have talked about it quite a bit so if you could add to this list that would be great.

Some people with good knowledge
DMC, FROTOU, KWANZA, DOGGY, EDO, FALLENHERO,

2zzge rods length 5.429 (wiseco)
7afe rods length 5.217 ( Pauter)

difference .212

a lot of info here about 4age
http://www.needfulthings.net/ostc/4age.htm

this is an idea have them make a connector 7afe to 4age with MAP

well im leaving the 7afte and going into 7agte mode but need a little help.
7afte boosted 15 psi and blow oil up and out by the spark plugs she still runs fine but i want a better head so.....

i tracked down a 4age geo prism wiring harness so i can keep MAP
wiring pinout will be easy to find i'll call geo for it.
also located a cylinder head and manifold (everything i need above of the block)
got 4age billet 8:5.1 pistons lined up
trying to get a good price on the 7afe rods
copper or metal head gasket


now i have a question i know a guy that has a rebuilt 4age cylinder head new valves p&p some titanium goodies the works but it was for a afm can i still use this head with a prism manifold and us MAP with a prism harness?

[thedevilmaycrie]

you will need the igniton system from the geo... ie distrib/igntor/coil... all the 4age heads at relitvly the same execpt one that i know of... talk with doggy though to make sure you get the right compression ratio... also you will need the ecu/wiring/sensors from the geo...

ok all sensors and all the ignition stuff ok

question i was just going to buy all new sensors + igntor and coil because the engine is kinda old. Will some of my sensor from the 7afe fit like the knock sensor?

now for compression i'll do a little searching around see if i can came up with some numbers.

on last question is the geo prism a OBD1 or 2?
thanks DMC

well, it wasn't obd2 becaus that system was adopted in 96

good obd1

i'm trying to figure out if i can use the 7afe harness or atleast some of it
or just swap the 4age harness in probably 4age harness with ecu

[thedevilmaycrie]

you HAVE to use the 4age harness and ecu.... and use the 7afe for the components that you are keeping to use the plugs off it

thats what i was trying to say that will most time consuming part wiring.
if i go with the 4age harness can i use a 4agze ecu because i'm going turbo and use the 4agze bar sensor?

or do i need a 4agze map harness?

[thedevilmaycrie]

i beleive 4agze harness and sensors are needed .... but dont quote me know that...

how about this

ummm ad ask fontu (the featured ride ..) he's the one selling it

[frotou]

Yeah, I'm selling my wiring harness and ecu because I don't want to take the chance to cut it (to splice in my celi) and to not be happy of it. That's the main reason I finally decide to go stand alone (my favourite now is autronic; www.autronic.com). I'm sure to have the bests results quickly and safer than the 4agze ecu and e manage.

Many sensors share the same signal to the ecu (4a and 7a) (air intake temp. , knock sensor, water temp.) but FIRST you choose the ecu you want with the harness if possible and ecu connectors. SECOND you have to go with the distributor of the ecu (who fit in the head) THIRD you complete with sensors who give the same signals to the ecu.

For an "4ag" head you need a 4ag ecu to read the head's distributor.

I don't know the Geo engine (not sale here in Canada) but if it's a 4age engine, take the wiring harness, distributor , ecu and map. After you can do like an 7afte ; the map (and ecu) read only the vacuum (don't forget a check valve to stop boost reaching map) and you'll need piggyback system to add fuel and adjust timming under boost.

The other way (what I was supposed to do) is to take the 4agze ecu/harness and complete it with the emanage. The 4agze ecu work great until 12 lbs of boost but after that it need help. What stop me to try it is the e manage is not compatible with the toyota dli system (distributorless ignition). The dli is share by the ae92 4agze (not all) ae101 4agze and also the supra 7mgte.

Later

Nik... there is no real advantage in using the MAP 4AGZE ecu over a MAP 4AGE ecu unless you plan on setting up DLI. You can modify the exsisting 7A harness to work, but it's a pretty painstaking task because you basically have to re-pin and rebuild most of the engine harness. The main focus should be the distributor, external coil/ignitor because most everything else is pretty similar. The TPS may be slightly different, but I can't imagine it being too much of a hassle. As far as the MAP sensors go, since you're gonna be rebuilding the harness anyway... get a better MAP sensor for boost. Everything else is pretty straight foreward.

[nik]

what do you recommend for a MAP sensor?

[nik]

all 20v are tvis right? can i do a black top ITB with harness and ecu to a 16v head along with 8.0:1 pistons. or is there a way to use a 20v head and turbo it but not use the tvis butterflys ?

[FallenHero]

20v were not TVIS they were vvt. No 4ag TVIS after 1989.

how can i get a 20v head to work with turbo?

[edo17982]

like every engine man....get CR ratio to 9:1 or even lower by getting forged pistons or a thicker head gasket.....

but will i have problems with vvt thats my main question or do i need to disable vvt and remove the butterflys?
