wiring :( - Toyota Nation Forum : Toyota Car and Truck Forums

|PuNiSh3R| · 04-13-2004, 05:26 PM

I am so confused and lost with all of the wiring i need to do for this 7afe swap.. I need to convert my 4af carb'd sr5 to a 7afe .. and just all of the wiring.. i'm gettin pretty sad right about now

Just don't know what to do anymore. I don't have any good diagrams.. chilton and haynes are worthless.. completely worthless.

........well, I'm no genius but....i highly doubt you can make your 4AFE Carb into 7AFE EFI....(are you trying to make it 7AFE EFI or carb?) wire harness...

|PuNiSh3R| · 04-13-2004, 10:18 PM

ugh.. read boy.. I am converting my 4af carb'd sr5.. into a 7afe driven car.. As in, I did an engine swap.. put in a 7afe.. and now I need to put in all 7afe shit.. wiring harnesses.. lots of shit to convert a pathetic sr5.

you dont get it do you????

the head on the 4AFE and 7AFE are the same!!!! 4A are 1600cc and 7A are 1800cc. just 4AFE has the carb on some models. 7AFE obviously came with EFI, but always can put 4AFE carb intake on 7A, but what really matters is the harness..... so is your 7AFE gonna be EFI or carbed??? i am offering help but if you aint gonna co-operate forget seeking help.

what are your plans? it'll make lifemuch easier if you tell us what your 7AFE conversion involves.

4Aaron GE · 04-15-2004, 08:42 AM

um.. the 4A-FE never had a carb. The 4A-F did.

TRDragoon · 04-15-2004, 03:29 PM

^oops yea LOL

|PuNiSh3R| · 04-15-2004, 04:49 PM

I don't want your help.. not to be an ass but you really demonstrate that you don't know what you are talking about.
1. E in Toyota engine code stands for Electronic.. so no, 4AFE cannot be carb'd.. that would be the 4AF. 2 very completely different wiring setups for carbureted and fuel injected engines.

2. When I state "7AFE DRIVEN CAR" I mean my 89 corolla will be powered by a 7AFE (remember, E stands for electronic fuel injection?)

3. The heads are not identical. The 7AFE intake ports come in at a steep angle.. The intake valves are rounded also.. so the head flows much better than your typical 4A head.. I tend to believe better than a G head even.

4. I was simply bitching and moaning. Trust me, I don't think you guys really have the remote technical expirence to help me in any of this. I've signed up with an Alldata.com DIY account and now have my 89 sr5 and a 93 corolla dx sedan (which is what I got my 7afe and harnesses and ecu from) so now I have complete wiring diagrams and good technical info.. no more following useless chilton and haynes manuals. So I'm pretty set now. That and I've ripped the dash and front harness out of my 89 rolla and am replacing them with the 93 dash and front harness.. which makes life a lot easier cuz everything plugs and plays now. Just need to get my hands on a cowl harness, and I'll really be set. Just have to incorporate my 89 combination switch (steering column controls) and the headlight motors into the 93 wiring.. and I'll be ready to rock,n,roll.

wow, what a way to be an ass...... and for someone going through all of this trouble for less than a 4a-ge would gain.... how ironic you say this

(and yes, there are proven numbers... racer25 has put a lot of work into his 7a-fe, keeping it n/a... bumping compression, rebuild, possibly a P&P i don't remember, along with tons of other work... and he only has a bit more torque than my stock 4a-ge and less hp than my 4a-ge)

toyotaspeed90 · 04-15-2004, 05:50 PM

& the E always gets dropped or added... it's just common (like 4ag, 7af, 4af etc... even works on other manufacturs.... b16, b17, b18, sr20, rb26 etc....)

|PuNiSh3R| · 04-15-2004, 05:57 PM

rofl.. his 7afe is shit then.. or he doesn't know what he is doing.. you can't just do things and add things to an engine with out thinking.. all work and parts must work in harmony together and compliment eachother.. if not, you won't get the desired gains.

Now, the 7afe is a 1.8l because it has a longer stroke over the 4a's.. this longer strokes dictates a higher low-end torque.. It is pretty pathetic that his 7a doesn't produce more torque than a stock 4age.
I plan to build my 7A up to produce it's top power peaks at no greater than 7K.. I don't plan on doing that to this current 7A.. I plan on getting another one that I can just work on when I have the cash and then when it's time I can just drop it in .. no hassles and no downtime for my car.

Anyway, stock, the 7A should have more torque and horses than the 4AGE to begin with, since it has a longer stroke and a larger displacement. Of course, differences in compression and etc make changes between the 2 engines. But you get my drift.

Ok Genius

than don't even bothering making threads

read what you have wrote, nothing is in detailed note... doesn''t even say what harness you're making, what you have done.

if you knew that you aint gonna get any answers, why would you post?

In my opinion, doing a 7AFE swap is really useless, especially when theres a direct 4AGE bluetop or redtop swap available.

something that'll impress me is having 7AGE swap done.

BTW, my ride is rock and rolling already

too bad your's aint

4Aaron GE · 04-15-2004, 10:16 PM

7A-GE is childs play. Dude in London had a 5S-GTE in his AE92 (SE92 then?) until it got totalled.

|PuNiSh3R| · 04-15-2004, 11:16 PM

That is talent.. putting in a non 4A engine in an ae92.. or ae86..

Hey, like I said before.. I just posted to vent some frustrations with this.. that is all. I know that nobody here could help me.. stop giving me your bullshit about a 4age swap.. you have no clue. No matter what I would need to change some things around because the way the SR5 is setup. It would've been a lot easier because most of the things from the 4AGE harness (dash harness, rear harness,) woulda plugged right up into my stuff.. since they share the same equipment. But that is life.. and I decided to go with a 7A, because there is no replacement to displacement.. I don't think the 4AGE is a big hot thing like you do.. Frankly, I think you are misinformed about how "well" the 4AGE performs. It's a great engine, but a properly built 7AFE will take a built 4AGE. I don't know what the hell Racer25 is doing with his 7A to only be getting slightly more torque than a stock 4AGE, since the 4AGE's are torqueless wonders to begin with, the idea of the 7A with it's longer stroke is to have more low end torque to begin with. It's like the F22A1.. no horsepower.. but a 144ft/lb's.. and that has a fricken 95mm stroke! Longer stroke means there is more leverage so it's easier to create power. Having more displacement further adds to horsepower potential. I guarantee my 7AFE will take your ride..
Only advantage to a 7AGE is having a stronger bottom end.. so you can rev higher, big deal.. if you want to create power at higher RPM's.. good for you, but it isn't needed. I can tune my engine in with parts and fuel delivery to get the best power at lower RPMs.. so while you are rev'ing the hell out of your 4AGE.. trying to hit 8K for your power peak, I'll be hitting my 6K power peak (which will be generating more power than your 4AGE) sooner.. and thus accelerating faster.
Get a clue.
IF rpms were everything.. why do the F1 Le Mans cars usually stick in the 8K range? You'd think with all that tech they'd be running like 14,000K and like omg.. ugh.. people and their 9,10,11K rpm 4AGEs are such jokes.. vtec wanna-be's.

toyotaspeed90 · 04-15-2004, 11:37 PM

uh.... read what i said.... he did produce more torque than me.... but not by a whole lot......

and racer25 not knowing what he's doing???

he could probably do the wiring in your car out of his head...... he's the most knowledgeable corolla guy i've ever met...... he's got his ae102 into a mid-high 15 keeping it n/a.... and his mango should be having over 200rwhp in a 2050lb car with driver..... (after his efi setup with megasquirt, then turbo setup)

RedruM · 04-16-2004, 12:31 AM

there are assholes, then morons, and even MR.THINK THEY KNOW IT ALL's but U Punisher... U'r a combo of all

when U have problems and post here for help.. well take it or get the fuck out and go to a honda board where everyone is a pro engine builder and F1 driver...THEY can help U

if U haven't noticed,, most ppl here like their slightly slower but very realiable fun driving cars , so if U dont like well leave, we dont need U or want U in our community
