I was thinking that the valve cover on this video is just fake but it actually seals a 20V head... can that be a possibility? is it possible that development after racing a 16V head with a 10000RPM limit gave birth to the 11000RPM 20V head? or its just that i am exagerrating it? Hope you can help me with my curiousity... Thanks ID Forumers! |

The diminishing returns line for the 4AGE is massive for N/A tuning D: |

Group: FORUM MODERATOR Posts: 9,272 Member No.: 30,193 Joined: Jul 25th 2008 Location: Plymouth, MN | A friend of mine had a built Corolla that revved to 10k with a 20v 4A, but some guy cut him off in traffic and he rear-ended him, totaling it. He currently has another one in the works. Not sure what all he had in the engine, though. |

Take this as advice. I never heard of a 4AGE going 10K RPM...Though I doubt you need THAT much power... | ||

¥5000 GET !! Group: Advanced Members Posts: 1,163 Member No.: 8,897 Joined: Jun 26th 2005 Location: Vancouver, Canada | ^Exactly, especially considering that the 4AG is an economy engine. Higher revs= higher compression ratio= higher octane gas needed. Unless you WANT a daily driven high-power 4AG for the track, don't even bother. To get the 10k, just get a 20v or do something stupider like an F20C. |

You have 87 posts. Please STFU and rethink what you're saying. As for the revs, I know the Atlantic engines had a limiter at about 11,500rpm, if my memory is correct.

Unregistered | Go out, call toyota and buy a Formula Atlantic engine. Or, take a large fat wad of cash, and your 4age 20valve to cosworth racing and have them make you one. There is no cheap way. |

Really? Look around more. Ive seen instances of them being pulled to 12k making 250ps.
Could it be a possibility? Sure. Likely? Not a snowballs chance in hell. its a 16v motor, plain and simple. The 16v engines actually do better at high rpms than the 20vs do. The 3-inlet valves on the intake start to develop dead spots at those rpms. But whats with the concern of the head? When RPMs are a concern, the issue isnt with the head- its with the block.
Econo engine? Boy what the FUKK are you smoking? A 4afe is an econo engine. The 4age was THE hottest engine of its displacement and aspiration in its day. Id say its equivilant to what the f20 was when it arrived. But im sure thats an econo engine too. And high revs do NOT equal high compression.
And mattw, you need to take your own advice and STFU yourself. What does his post count of 87 have to do with what he said? What outcome would you like him to come to as he rethinks about what he said? No no, we dont want a curious individual asking initial-d related auto question in the auto section of an initial d forum. grow up.

This guy speaketh the truth. Also 16v blocks are internally stronger for forced induction compared to their 20v counterparts as their pistons etc. are too flimsy for it. Also want a list to make your very own formula atlantic engine? It will closely resemble:

We're the People's Front of Judea! Group: Advanced Members Posts: 13,123 Member No.: 1,355 Joined: Feb 28th 2004 Location: Las Vegas, Nevada | Half right. All the 20vs use a 7 rib block, which is thought to be the strognest of the blocks (They switched over to them around in 86-87). And the silvertop 20vs actually use the same crank and rods as the Gze supercharged 4agzes, just the pistons are swapped. Blacktops are a different story, with both lighter rods and crank. btw badass read on those specs. |

Even though he did flame there, still not a bright idea to make a reference to Initial D. It might/will make you look like a ricer, no lesser. Anyways, some serious sh*t must be put in to actually make this thing withstandable to the 10K Punishment, since the only ones that can is the engines of some SELECT sport bikes. *Cough*Hayabusa*Cough* | ||

FYI, most sportbikes go well over 10k. Most are in the 13-15k rpm range. | ||

And yet it sounds like it's only doing at least 8000 RPM while trying to throw you off. | ||

IDW Member Group: Members Posts: 15 Member No.: 25,814 Joined: Aug 10th 2007 Location: KOP, PA | formula atlantic makes 240hp at 8400 and redline is between 10-12k rpm. Nice honestly, 5 valve isnt really that good, and its even worse at high RPM. The basic at building a high revving engine is balance. Easiest way to get high rpm is squaring the rod and stroke ratio, because that balances the engine internals. also the lighter the better. knife edging the crank will help, so will a windage tray Headwork will include dual spring valves and stronger components. ss/titanium valves and non titanium retainers. port polish and 3 angle valvejob. You dont need high CR to get high revs, but if you want power, then youll need a high CR, so its kind redundant, lol Cams, obviously high lift/duration will help you get power too. so will ITB's or a single runner setup. free floating pistons will be your best friend. if you dont have oil squirters, get them. And you idle will be high (1-2k) lol If i missed anything feel free to add |

IMPORTANT! Because valve float at 11k will destroy your entire valvetrain. And why not a 5-angle job? | ||

IDW Member Group: Members Posts: 15 Member No.: 25,814 Joined: Aug 10th 2007 Location: KOP, PA | You could, but if this is a street engine, I'm not sure youll need/want the full 5 angle job. It'll wear the seats quicker with the 5 angle job. its the same reason I said no titanium retainers, they wear too quickly. If you didnt care about longevity, I'd say build the thing to F1 specs. |

Srsly I'm the Stig? Group: Advanced Members Posts: 1,116 Member No.: 11,448 Joined: Aug 24th 2005 Location: SoCal 310 | If its a street engine then why build it to 11k RPM? Last time I checked, Formula Atlantic engines were designed to run a maximum of one season, but its all in the tuning and how aggressive he drives it. |

*slaps EA99* You stealin' my engine again =P C56s Trans, there are a few half cuts with the PFL AE111s and AE101s around so C56 shouldn't be too hard to find. Depends on your location too I guess mate =| 4A-GE reaching 10K+ have seen before, both 16V and 20V can do it though 20V requires a lot of work and $$$ because its an ass lol, its just naturally more expensive to work on the 20V than the 16V. | ||
