@3:28 What da heck dude? There was a Nissan March SuperTurbo with a supercharger and turbocharger combined in the late 80ies.

Hi banpeiet! You have a very large number of excellent videos! Keep up the good work - Billzilla.

Thanks for the compliment! I just released a video about the AE86 Sports Package, so perhaps that might interest you as well. 😉

+Captain Bacon you're welcome!

+Abdel Mohabir thanks! How could I have forgotten that one! Unfortunately you just missed the update video by a few days...

Ok i'll be sure to check it out! and your welcome

+Nick Ward thanks! Good to know that!

It depends what you want to achieve really. The 20Vs are better as standard but throw any money at any of the 4A-GE engines and your power ceiling is about the same. A good port and polish, some big cams, a good exhaust and up the compression and you can get 180bhp with any of these engines naturally aspirated and upwards if you want to go crazy (see Formula Atlantic 240bhp 4A-GE). Any of these engines will take forced induction on low boost with no issues but if you want to up the boost you'll have to replace a lot of the parts in the naturally aspirated engines. The 4A-GZE is more suitable for higher boost levels but if you want more than 200bhp you'll probably want to replace some of the internals regardless. So in summary: It depends. NA screamer, torquey daily or highly boosted fuel guzzler. If you want to get crazy power and will be replacing the internals and doing lots of work anyway then I would say it doesn't matter (probably avoid the 3 rib blue top). These engines aren't exactly 100% interchangeable though so consider the wiring loom nightmare if swapping from one type to another.

For fuel economy you'll be best with a blue top or a red & black top (big port 16V with T-VIS) as you get nice low end torque and very good fuel vaporisation due to the asymmetric induction.

The six bolt flywheel was only used on the 4ac, so it could be either a head swap or someone installed a flywheel for a 4ac?

+turb0negro Gabriel yes sorry for that. I still haven't made that video yet and it's still on my to-do list. 🙄

How so? Mine worked great after 25 years and 200k miles. I had the second one shown 88KW I believe he said. It's similar tech to what the Taurus SHO and Porsche 959 were using only earlier.

PGTMR2 i should have look into it more before making a comment tbh

It's cool. It's a fascinating subject, there's all kinds of trick intakes out there designed to keep the air moving at a high velocity.

PGTMR2 yeah it is I never researched 4ages as much as other engines like I do with mopar small blocks

My current car has a 2 stage intake, 4 different versions of it too. I was so fascinated by it, I ended up getting all 4. Each one changes where peak power is.

Thanks for the correction! However Toyota's official (80s) documentation on the tvis says it stands for induction, not intake: 3sgte.org/page_13.htm I learned thanks to many comments that it's not the intake that changes, but the induction changes do to the increased velocity

banpeinet that’s right, even if you take a look at how the engine works you see that it’s the induction that changes, but for whatever reason I always heard that the system is called Toyota variable intake system, probably it’s just a common misconception

banpeinet thank you for responding by the way, you have an awesome car and it’s awesome to se someone with a lot of knowledge about this old boxes

Now this is a how conversations should be carried. A kind correction and a humble acceptance.

The one that isn't revved over 2500rpm 😆 In all seriousness, these engines weren't made for fuel economy as they were performance engines. My guess the most efficient engine would be the later 20v due to better software

+taunusv4power have you already counted the ribs? :p

banpeinet hahaha! i just opened the bonnet to see the ribs but the exhaust manifold cover is on the way. the block is black though and is an early 1986 one so i'm pretty sure is a first gen.

+taunusv4power I knew people would check out! :) Yes if the engine looks legit and never has been swapped it has to be one. Is your Celica an original Peruvian delivered car?

banpeinet the engine was never changed and it's not a Peruvian model, mine is a JDM one that my uncle bought in Japan 22 years ago for my grandfather, he imported it and made a LHD conversion here. :D

+taunusv4power wow, that's an awesome car than! Cherish it and keep it in the family!

Yes, I stand corrected here: it is a twin cam as it has two cam shafts. The major difference with the 4AGE is that the 4AFE has a very narrow angle and it has a single cam gear.

According to the Manga the engine is a dry sumped silvertop based 4AGE, used for rallying. So, in contrary to popular believe, it is not the Formula Atlantic engine.

banpeinet actually Toyota engines from 80s were called as Pegasus and LASRE Brands

banpeinet Shinji uses 4A-GELU

+Compaxius Camiones Pegasus was an acronym used for the suspension and lasre was as an acronym for lightweight advanced super response engine. But they used that acronym for the 3a-u on itsukis car as well. It was just a marketing term for the new generation of Toyota engines

banpeinet well i saw a LASRE Engine in a E80(not AE86)Sprinter

Thanks for the correction. Maybe it didn't come with the 4AGE in the US, but it surely came with the 4AGE (and 4AFE) in both Japan and Europe.

Thats not true. im pretty sure no celica ever came with a 4age engine for that matter, earlier gen celica's came with perfered 22R engines some carb some fuel injected. The Celica and Supra Line up never came with 4age engines. Correct if im wrong with a source.

As I said in my reply: maybe they didn't come with the 4AGE in the US, but _outside_ the US they were available. The 22R was not available on a Celica outside the US either. Also I actually owned a Toyota Celica GT-S AA63 in the past, and I'm absolutely certain about it having a factory 4AGE as it was on the firewall plate. If you need a source, please have a look at Wikipedia: en.wikipedia.org/wiki/Toyota_Celica#Third_generation_.28A60.3B_1981.E2.80.931985.29 en.wikipedia.org/wiki/Toyota_Celica#Fourth_generation_.28T160.3B_1985.E2.80.931989.29 And if that isn't enough proof, here are the Japanese brochures for the third and fourth generations: www.en.japanclassic.ru/booklets/147-toyota-celica-1981-a60.html www.en.japanclassic.ru/booklets/149-toyota-celica-1985-t160.html

i have owned a 1987 celica st162 and it had a 3sge motor.

+Haris Ansari yes that generation also featured a couple of other engines, including the 3sge

Thank you for your complement! 👍 Not sure if I would do the rotary engines: those have been covered in many videos and I'm not an expert on those engines myself

Yes indeed! ;)

Yes, thank you for sending me the link. I think I must have forgotten to add the link in the end after uploading the video. :)

No worries :) very thorough and educational video, thanks for uploading.

+micheal alexander Thank you so much for your constructive comment. Look, i didn't say anywhere that I'm a fully fledged mechanic with experience of rebuilding all 4age engines. In contrary: I said this was a primer for people, giving an overview with the differences between each model. If you feel you were deceived by the title because you didn't read the description of this video not listened to the introduction of the video, don't vent that in the comments... About the copying of what is available on the internet: I didn't need to. Most of that information was readily available on AEU86 (which I have been running since 2004), and the additional information from reliable sources (club4ag and Billzilla) and I simply provided what wasn't there yet. Back when I created this video I planned to make follow up videos that are in depth about each and every model. As you may have seen I haven't had the time to create those and I'll surely keep your advice on the back of my mind once I'm going to do so.

You said this to a guy... that owns an AE86 woth a 4age....

+hectorae86 b2 aan b3, over. Watzeggie?

Ja, sorry hoor, is een van mijn minder sterke kwaliteiten :P Kan me mateloos irriteren aan uitspraken zoals volves in plaats van valves, maar goed, dat doet er eigenlijk helemaal niet toe. Maar dan nog een ander ding, de big-port wordt onderin eigenlijk alleen maar iets minder krachtig zonder T-VIS. Het scheelt niet veel, maar het afsluiten van 1 van de poorten zorgt ervoor dat er sneller een soort van lucht ram effect gecreeërd wordt, iets wat zonder T-VIS alleen in de hogere toeren gebeurt.

Was onder de indruk dat over het algemeen mijn uitspraak redelijk goed is. Maar goed, dat weet je natuurlijk nooit totdat iemand er wat van zegt. Zal er in de toekomst op letten. ;) Over de tvis: klopt als je alleen dat doet op een standaard ECU. Met een remap heeft het juist weer een tegenovergesteld effect, en dat is waar de mythe vandaan komt. Dus op een stock motor heeft alleen maar het tegenover gestelde effect. En over het ram effect: klopt ook.
