Tuner Ideas Needed

[niky]

oh??!! 240 is a realistic number??.. so 9.5K to 10K rpms are also do able??... if this project will push through it will be my weekend stress reliever! and I may have to sell my car for this...

What I mean is: It's possible to have a 4AGE at 240 hp. Sorry, I took so long to answer, I had to look it up as I'd forgotten the race series... the 4AG with that much power is the one used in the Formula Atlantic series... where it is used in open-wheeled racecars.

But it's not a streetable engine. That $699 engine you saw may be a secondhand race engine, BUT:

It'll be hard to install... almost all the auxilliaries are different and you'll have to customize a lot.



You won't get the full 240 hp. See those long intake trumpets and extended exhaust? When you chuck those for not fitting underneath the hood of the AE86, you lose some of the Formula Atlantic's power.

It won't be streetable. Meaning, it'll rev badly (you'll have to set idle at 2000 rpm or so), it'll probably buck and bang at low revs if you don't give it full throttle, and you won't pass emissions testing. And your fuel economy will suck.

And, best of all. It'll be expensive to buy and maintain. Brand new ones cost about 18,000 dollars.

It's much more realistic to buy a 20V or a 4AGZE and tune up from there. With a well-built and modified 20V, you can get maybe 175-180 hp. With the 4AGZE, maybe 200+, but you'll need to modify the engine internals, too. Not quite as much, but more realistic, unless you're a millionaire.

But if you do have a lot to spend, and fancy having around 300 hp or so under the hood, go for DMF's SR20DET conversion... the SR20DET gives you about 200-250 hp as base (but the 250 hp versions might be expensive), and it can be tuned for up to 500 hp (tons of money), or 300 hp (just lots of money, but at least you can do this on the stock internals). This'll be cheaper than finding, buying and maintaining a Formula Atlantic engine. You can tune a 4AG for this much power, but it'll be harder to do.
