20V swap.

[Flashmn]

Ok I think I've made up my mind about this. What are the most common issues in swapping the 20V into an AE92?

Clutch isnt going to be an issue, I have access to several sizes. Wiring harness should come with the engine package as well as ECU, so I'm just going to do a separate ECU-engine installation and leave the chassis harness out of it. I'll be using my C52 transmission. Any other things I should be aware of?

A friend of mine thinks I'm crazy for wanting to drop ~$1500 (including shipping) on a complete Blacktop (engine, ECU, harness, alt, etc, even tranny which I wouldn't use).

I guess you would also want the alternator and AC compressor if you have / want to keep AC. I'm not sure if the pulley groove & width are the same for the alternator and such between a 4AFE and a 4AGE.

No sweat, my AC is busted anyways and its a universal sanden compressor on it so no issues with that...

I'm paying 1000bucks for a ST, I'm not sure 5hp difference warrants the BT prices.

Look in my old swap thread.

If you want to keep power steering you'll need the lines and remote reservoir from a gts.

Make sure you get a afm. A lot of them don't come with them and you need it.

There is a camry afm that works though.

Take apart you ecu and check it for blown caps... it seems to happen a lot.

You'll need to pipe the speed signal from the gauge cluster to the ecu or you'll end up in limp mode.

Looking back I probably should have gone with a black top from the start.

My car doent have power steering.

Blacktop is minimum 500 euros more, dont have that kind of money to spend. Considering if I get hired for real next spring I'll be getting a F150 SVT to replace the corolla. So this is more like, put together somehow to make it rideable and then sell it when I find out.

in real world figures (not the importers saying 'this is 5 million hp... buy it now!')... the BT actually makes 20-25whp more than a silvertop.

A silvertop is around 120whp
A blacktop is around 140-145whp

both in stock trim.

If you still decide to go with an ST find a later version as they have larger ITB's over the earlier ones (by 2mm each, I believe)

Right now its all about the money.

[toyotaspeed90]

I understand.

I'm just letting you know.... people think "20v" and go 'holy shit that things gotta be fast.... that's awesome'.... when in reality the silvertop makes all of about 10whp more than a stock US smallport...

I think the 20V in your case might be a better idea.... since you want the car more for reliability it's more likely that the 20V would have lower miles.... and the coolant lines should allow you to use the stock 4afe radiator as well.

[Flashmn]

Yeah I know its not as good as they claim. Still. people do look at it like "OMG Takumi uses this" and hence I might get 2000 dollars for my car, rather than 1000 when I sell it..

[kwint]

Wow I didn't know the blacktop made that much more power? Is it just better made than the silvertop? Or does it have to do with the afm?

lighter internals allowing higher revs, also has 11.5:1 vs 10.5:1 compression ratio.

However it leaves you a bigger room for a turbo or supercharger add-on versus a blacktop Well, supercharger in your case so you have boost allaround.

(incase anyone dont know... Silvertops are better for anyone wanting to do a forced-induction because of it's lower compression ratio. Preferred you go even lower tho, but I read some that threw a turbo on stock silvertops and runs fine. I'm just spreading the legs a lot more on mine for killer HP... expensive parts.... hopefully worth it)

Since I've been curious / fairly serious about swapping a Blacktop into my All-Trac... do you need to check all of these things you mentioned above for a BT as well?

Edit: another thought I had... what about replacement parts, being that these motors were pretty much only available in Japan? Like you need a new head gasket, or fuel injector o-rings, valve springs, etc.

Totally forgot about those items. Thanks.

[Flashmn]

Parts should be available for order from toyota....

Vin diesel voice: "Overnight parts from japan"

As for high hp etc, thats not really what I'm looking for right now. I'm looking into making my car reliable enough to take me to work and back home for couple of months, after which I'm selling it and getting a truck as I live in the sticks and I'll be building a house, so I need the cargo capacity.
For the money you spend on getting high output from a toyota, you can get a way better car with a much modern chassis, ok a trucks not exactly it.

But for example, my mother ordered the new model Alfa Romeo for herself, its got a 1.4 liter turbo engine with 170hp and 250Nm (180ft-lb) torque, its ridiculous, you get 4.3liters/100km with it, which is around 50mpg (US). Gives a whole new perspective into things and thats the econo engine. The sporty engine is a 1.8 liter 235hp version
