20V Ae86 swap....distributor help - Toyota Nation Forum : Toyota Car and Truck Forums

etxxz · 02-20-2005, 08:44 AM

Wazup my people:

After lots of engine problems with my $100 sr5, i've decided and ordered a 20V engine set. I got everything i'll need minus the fuel pump. I have the right mechanic for the job and since i'm helping out i'd like to know HOW and WHERE to move the distributor since the firewall is in the way (i was told not to cut/hammer)

And basically anything associated with moving, or common problems (not commong since few people do this swaps). Help is appreciated. I'll be cruising around the toyotanation forums meanwhile

I'll be posting lots of pics

There is no way around it if you're planning on using the stock dizzy. There are re-location kits that include custom parts to move the dizzy to the front of the engine (on-to the cam gear) but these kits are quite expensive. I doubt it's the sort of thing someone can custom fab up either. For the most part... you have to smash in the firewall unless you don't mind searching for a relocation kit. There's nothing wrong with smashing the firewall... and the dizzy isn't the ONLY thing that's not gonna fit back there. The thermostat housing isn't gonna fit either... And... whoever told you not to cut/smash/modify the firewall... well, I'm telling you now... they're overly worried about something very common with custom swaps. Gabe Tyler's F20C powered AE86 had to have the entire firewall chopped off to fit the tranny... and he races that car... so it's not a big thing.

I'm not worried about the distributor, waterlines or the thermostat anymore. I read tons about solutions, now its up to the mech, me and lots of time. I'm still in the dark about using my sr5 gas tank. I'll be fine if i use an aftermarket fuel pump and make custom fuel lines right?

heh this will be of fun. Thanks K

The tanks between the SR5 and GTS are the same... except the GTS has a built in fuel pump and the lines are routed slightly different. You can use the SR5 tank with an external pump or something... What comes to my mind right away would be a 280zx fuel pump, which is external and should be pretty easy to hook up to the stock SR5 lines. I wouldn't worry so much about the mechanical stuff as I would about the electrical... Mechanical is easy...

etxxz · 02-20-2005, 06:56 PM

yeah and so i was told by the mech i'll be working with.
You have a 20V sr5, what fuel pump and tranny did you use?

i'll look online for something.
So frikin pumped

btw* looking from a $$ perspective, what will a lightly modded 20v 4age Sr5 be worth? (coilovers/springs, exhaust, strut bars f&r)

cutting/hammering the firewall is imho the worst option there is. I'd either go for distributorless ignition or get the kit to mount it up front.
Both will cause you shitload of problems. 1) You wont be able to change your distributor cap, rotor, wires whatever without removing the engine. 2) You wont be able to run the heater or you might damage it, etc as its right behind the spot you need to bang in/cut.

Kwanza's right. there's no other way around it except the relocation kit which (last i checked) would cost you close to $800US. and about the cutting of the firewall, there's tons of option on how to get back the strength you lost from the cutting. just need proper reinforcements. goodluck!

here's what i did...

We've already gone over this... and basically... you're worried about things you've never had to deal with. Setting up a distributor-less set-up is costly in terms of parts, and tuning. Getting a front mount kit would be costly and fairly hard to find, because almost all of the kits are from Japan. Why do all that when you can just hammer back the firewall a bit? I had mine set-up like that, and in the AE86, you can get it far back enough to where you can slide in/out the distributor cap. The wires clip out from the top... so that's not even an issue. You may be made out of money, and you may think you can set up all of these cool DLI set-ups... but most people would rather work with what they have. Smashing the firewall = $0.00... Standalone with ignition timing, DLI/DIS/EDIS = 500 dollars or so in parts for a DIY megasquirt with EDIS, or a different name brand standalone for thousands. Front mount dizzy kit = 500.00+... With that staring you in the face... 0.00 dollars looks really really good... but you won't agree just because. FYI... in an AE86... you CAN run lines to the heater core... so don't take guesses brotha.

right and I'd never go through it because I think its a bad solution to a minimal problem.

Well if you're a broke ass mofo you shouldnt even think about doing a swap with an engine that isnt native to that model, because there will always be problems involved needing solutions which will increase costs.

etxxz · 02-21-2005, 10:16 AM

i really see no problem his point...and no structural danger in cutting the firewall either, exept cost efficiency By adding a strutbar i can solve this problem and save around $750. (ebay~$25shipped).

heh i not a broke ass mofo, but i am 18 and full time college student making my $$ VERY limited...believe it or not $750 is a shit lotta money,

I still need comments on using my Sr5 tranny with this swap.
Kwanza you've done it, what did you do?

Howbout a huge gaping hole.. I see that as a problem... Shit flying in etc, I would NEVER cut a hole in the firewall just as an easy way out.
Over here you wouldnt even pass inspection with a hole in the firewall, dunno about you guys.

Well... maybe you should swap in an engine that has less hassles in it.

etxxz · 02-21-2005, 01:08 PM

i wont be the one getting hassled, i have a beautifull 1999 acura Tl...the sr5 its just a project car, in any case the mechanic is the one getting hassled. BTW i'm meeting with him in about 2hours

Still no ideas on wether i need a GTS bellhousing or if my stock SR5 tranny will work. Ideas?

Oh, another important thing, i need the O2 sensor that goes in the downpipe right? or can the engine live withought it? (i know my obd II TL engine will die withought its O2 sensors)

micro214_kp61 · 02-21-2005, 02:17 PM

Flasmn... have you done a 20V swap on a RWD car?

Flashmn · 02-21-2005, 03:08 PM

and what does that have to do with cutting the firewall or not?

Didnt your momma ever tell you if you didnt have anything wise to add, dont say anything?

You're just constantly starting to argue whatever I say, here it starts again, you jealous that I'm so much smarter than you are or that I have double the postcount than you? Gee maybe its because I'm giving advice to others, since I've been doing this for the past 5 years as more than just a hobby?

Ignore flashmn... he likes to think he knows what he's talking about... but his immature self-centered behavior more than explains his information.

Back on topic... you probably cannot use the SR5 bellhousing because the 4AGE exhaust manifold will be in the way of the SR5 slave cylinder. I personally simply used a GTS tranny. Of course, last time around flashmn reccomended you get a custom header made... but that's like solving a math problem by paying someone to do it. Best bet would be to get a GTS bellhousing. That's the only real difference between the SR5 tranny and GTS tranny... the bellhousings. Also... you won't need the secondary O2 unless you're gonna wire up everything according to the JDM ae101 specs... for the most part, all you need is the primary O2, which is a 4 wire O2 that you can source from most 97+ toyotas. I can't even say for sure if the JDM AE101 has a secondary O2... but most likely it does.

A minimal problem you plan on solving by spending more than the cost of the actual engine... That's just brillaint...

If you're so rich... go get your carbs dynoed so we can all see your blacktop 20V ass kickin 4AF power... BTW, this swap has nothing to do with me. I don't need help from the likes of you. I've gone through more engine swaps than you can even imagine... so why do you think you can even do/say to enlighten me? Also... it's not a matter of money with me. It is with most people... but with me... it's all about practicality. FYI... I am setting up a standalone with EDIS for my next 20V swap...

Flashmn: you've reached an all-time low in terms of petty-ness. I always figured you for the crybaby type... but never realized how much attention you really need. If anyone doesn't have anything wise to say... it's you. All you've been saying is "No, No, NO"... why? because you wanna be "right"... you wanna get off on how everyone is below you and you're soo smart and we all need your knowledge... Get off the ego trip buddy. As for the firewall mod, as I keep trying to explain... you don't need to cut a hole with the AE86. You just need to pound it back a bit. Even if you do cut a hole... nothing says you have to leave it wide open. You can seal the hole with some dynamat or something... no biggie. As far as I'm concerned... you're the only jealous one... you're jealous that you're ideas aren't being taken.
