Depending of which cam you use 505 performance were saying that if i use the proper camshaft itll help me having more torque than the stock head depending where the cam is suppose to be.... but i have to be honest im doing a lot of research right now for that reason, i dont wanna loose all of the low end torque but having a crazy amount in the upper RPM

 

[VinceTj]

could be a nice little motor. with the right gears in the axles and 4:1 t-case should crawl great.

I'm keeping my 2.5 stock for now but might build a 4 banger for a buggy down the road.

Eventually i want 4:56 with 33in tires

If your going to the AX-15, think about 4.88s, I have the 2.5 / AX5 and 4.88s on 33"s and I have to watch my sped, it will creep up to 70 or 75 without any effort.

 

[VinceTj]

4.88 i think its too high for what im planning to do with it

Transmission fix! the tranny fluid was brown i flushed it and replaced it and i had air in the clutch system

 

[DasfieldmarshelsYJ]

How's this going?

Im a newbee to all the mechanical stuff, but after reading the forum for a couple of months its good to see someone doing things with the 2.5. IMHO it gets such a bad rap in general. Im in, and anxious to see your outcome!!!

How's this going?

Slow as hell got sent on exercise

Im still reading and wish you the best.

i asked about the 2.5 stoker earlier on another thread here and got made fun of. lol. I think it'd be cool to improve the little four banger. sure it might take some bucks, as will any swap, but you wont have to custom make any mounts or anything! bolt right in. definitely subbing. lol.

I guess I don't get the appeal. Let's say you put $2000 into custom decking and machine work, built internals, etc. and you get another 30 HP out of it. Now you're at what, 150HP? Wouldn't it make more sense to take that same money and do a swap for a more stout motor? Not making fun of you or anything, just trying to understand why this would be an option when it seems the payout is inadequate. Other than the "because I can" factor, what's the appeal?

My thinking is, in an emissions state you can get more power without the headache of the smog police (Me).

Im interested as well as I have done MANY 305 > 400 smallblock swaps intentionally to fool the smog boys before I became an inspector (probably still would do it)...
To still have a "2.5L" with 30ish increased HP would be nice. Im still into doing a 5.2L swap, but want to follow this too.

Can the OP post a link to the 505 parts and/or website?

 

[89quest]

After reading some of the horror stories connected to buying some of the "remanufactured engines" I went on 505 webb site after reading your post and considering purchasing one of their 2.5 stroker engines! I t will just take that much longer to save for it.

 

[Ibuildembig]

The problem is you cannot change the issues the 2.5 has just by bolting stuff on and it in it. For an extra thirty horse put a bottle on it,,,,the result will be the same.

 

[x5050160]

So I assume this build is dead

 

[econjo]

I sure hope not! I've been looking to do this for a while.

505 performance is saying 185 hp and 200 ft lbs compare this to a stock 4.0L at 190 hp and 225 ft lbs not frickin bad for a $3k drop in motor. I say this is very appealing vs a 4.0L swap. Plus an ax15 conversion I would think. a tranny upgrade would be a given anyway . :drinks:

 

[jdubby]

I always thought of this as a challenge to see how much horse power we can get from our little 4-bangers...I would definitley like to see if this was ever completed...or if anyone else has put this kind of work into their 4-banger!

 

[LilBlueYJ]

how reliable do you think the 4 banger would be at 185 hp? Are stroker engines reliable to begin with?
