Re: which engine has more potential for more power?

possibly using custom H beam forged rods I don't think aftermarket rods would be necessary for the greater majority of applications, likely including this one. I went for aftermarket rods to decrease weight and be able to use 20 mm wrist pin pistons. I'm using 20v pistons and a 20v head. There are ...

Re: which engine has more potential for more power?

LongGrain summed it up pretty well. All you need is cams and compression and a 16v will walk on a stock 20v. While I can't guarantee anything to work and while it does greatly depend on how you build it the reason I promote this setup is not that I think it's the best thing that could ever be but b...

High resolution scan for AE101 ITB gasket

I've started scanning things for the purpose of reverse engineering and thought I'd share. Here's the gasket between the intake manifold and throttle bodies for AE101 throttles. The original is 70 x 100 mm at 4800 DPI. If photobucket is being mean somehow, not allowing it, then let me know and I'll ...

I would not agree with that, especially when paired with an O2 sensor and the ability to remap fuel trims. My experience with AFMs has shown them to be extremely accurate consistent and adaptable. As far as stock ECUs go I would take AFM over MAP 9 times out of 10 because you can do a lot more VE m...

Re: which engine has more potential for more power?

According to an old motorweek video the transverse bigport 4As were down in power because the intake manifold was compromised for packaging.

If I remember correctly, 4A-F transmissions have a taller final drive than the 4A-G. There shouldn't be any problem bolting them up.

Tomeis 20v cams haven't been on the market for long, and demand has exceeded supply for most of that time. Pistons and cranks, on the other hand, were never going to sell well in the US market.

Also AE86 driving is about character, balance, and driver connection.

There's a reason it has the reputation it does. 170-180 is plenty, as long ...

Re: Megasquirt coil on plug questions/ ignition questions

Power wise you should not see much difference. However, getting the injection timing just right will help save some fuel. Going to sequential also helps throttle response (or at least it did for me).
