How much power can a 3100 make?

What's better about a 3400 block over the 3100 other then being .3L bigger? I see a lot of good numbers for it but seems like no one builds 3100s.

Check my Fiero thread. 214WHP. 3400 with a cam and 3500 manifolds. Very mild cam at that...

I'm shooting for 200+ hp out of it Naturally Aspirated. Plans of caming it, 3400 topswap, maybe a higher compression, full exhaust, and tuned. I don't see why its not possible but others have told me otherwise.

Sans the cam and compression, that sounds like what I want out of my 3100 (I like the idea of being able to beat a stock Grand Prix GT with an engine that is over half a liter smaller). If your engine bay has enough room, you can also get a big cone filter like this one, which would compliment the top end swap quite well:

It's definitely possible, and it sounds like all the stuff on your list should put it over that number.

wow everybody is horny for the 3500 swap even though there isnt many crank triggers.

"yeah, go ehead, swap the motor, you just wont be able to make it run till a part is produced in a higher quantity" lol

Exactly...

You can easily make 200 CRANK hp on a 3400... Geoff or Heavywoody on Beretta.net has a 3400 that has some old WOT-Tech port work done to it and LS6 springs and and thats it, and he put down 184 WHP, 204 WTQ through his 282 5-speed in his beretta, I did the tuning on it and it was just a really generic tune, I know we could probably squeeze more out of it for on the road but we dialed in the A/F on a dyno.

Also with a 3500 you have to spend way more time making or fabricating motor mounts since boss's changed on the block and there is the added cost of the crank trigger and TB adapter if you want to run the 3500 upper, so I say if this is his daily, he could source many of the parts have them waiting and then do a full 3400 top end swap on his 3100, possibly a mild cam and tune it and be done in a weekend if he knows what he's doing. Minus the 5-speed swap... that well in a GP may take longer to do.

It'll be easier and cheaper to swap in a 3500 buddy. 200 at the crank for around $600.

Add a tune and youre set

I will be doing a 5 speed swap also. I'm shooting for 200+ hp out of it Naturally Aspirated. Plans of caming it, 3400 topswap, maybe a higher compression, full exhaust, and tuned. I don't see why its not possible but others have told me otherwise.

I don't know of any particular power limits of the engine, but the stock transmission fails before the engine does from what I recall.

I looking into doing a little build on my 96 SE. What kind of power can a 3100v6 make. And is it out of the question to shoot for 200hp at the crank?
