how much HP does the 4age made?, silver top vs black top Options

[vi-tuyen]

hi guys. I am about to do the 4age swap.

I want to know how many HP does the silver top made? and how many does the black top made?

To appropriately answer...

haters will say the 20V is "underpowered" and only makes marginally more power than the 5SFE and much less torque... but I'll bet those people haven't really seen the race track (not drag strip) nor have they ever driven an n/a horsepower motor before. They all essentially act the same.

That said... the 4AG isn't for everyone... it's not a daily driver sort of engine that makes driving around town in stop/go traffic easier than even the 7AFE... Think about what you're looking for first. If you're just gonna drive normally, but want more power... you should look for something with more torque (4AGZE?)... but if you want a real enthusiast motor that is very tunable... the 20V is great.

As for which engine to choose... Blacktop 20V all the way. I myself had both a silvertop and blacktop powered AE86 at one point or another... and the blacktop makes probably 20 horsepower or so better... not to mention it's MAP sensored which makes it considerably more tunable in stock trim. The silvertop does have larger rods (stronger internals)... but that's insignificant unless you're looking at boost or something. If you're thinking about just a mildly tuned street motor... the 20V is a great platform for that... and more if you do AutoX and stuff too.

Oh yeah... the silvertop may have been overrated at 160 hp (makes closer to 145-150)... but the blacktop certainly is a 160-170 hp engine. There have been AE86 guys who dyno 140 whp, which places the engine in the 160-170 hp range stock... while others do as well as 150 whp piggybacked. At the same time... some ghetto rigged setups do worse.
