Engine boost
andyman - I was wondering the same thing the other day. I did about a half hour of looking around on the internet for bolt in improvements, but didn't find much. I also didn't find a cam solution either. Lots of experience here though, so I'm interested in the feedback from the group.

sorry but there is no such thing as "bolt on performance" for that 2.5. I've been there a tried a few things such as cold air/kn plus aftermarket MAF and nothing will do anything except empty your wallet. All I can say - if you wanted performance you should have bought the 4.0.

Bolt on performance myth
greenpus - Thanks for the input. I did read up on the 2.3l upgrades (not much written on the 2.5l) the other night, and I did catch the KN cold air intake. It seems that from my reading, most one could hope for might be a 2-3 hp improvement, which wouldn't be noticable. When I bought my 2000 Ranger, I was doing a long commute, so the emphasis was on gas mileage rather than power. Because my wife didn't drive standard, I had opted for the automatic as well, so winding it out a bit was out of the equation. The combination of both lends to lack of pickup and really my only disappointment in the driving experience. Now I get my fun winding up my S2000!!

Thanks for the research. I had friends with the turbo charged 2.3l; one Mustang and one Thunderbird. Quick vehicles for their day. It's interesting reading in that it appears that the 2.5l's lineage may trace to the 2.3l. It may help in finding performance solutions. I appreciate your input.

PS - My brother had a 70 Thunderbird, 2 door though with the squared off rear window (not the sloped rear window). That was a fun car to drive: catching rubber when it would shift into second gear. That 429 had plenty of torque!

Yes, it does, but the 2.5L needs internal and fuel management upgrades before you can reliable turbocharge or supercharge it. That being said, if you do so, you can produce a LOT of power from these engines. The initial price tag is probably prohibitive though.

A novelty
Khan - A cool project...if only the expense justified the end. If the 'end' is fun, where the return on investment is secondary or not at all, it could be a rewarding project. Thanks for posting!

Grind the crank to accept 250 chevy rods get a set of Keith black pistos to go with the rods. Open the exhaust ports. They make some really hot cams for this engine. You would be surprised at how much you can get out of it. It does cost some bucks.
