Without machine work, and NA what is the horsepower I can expect? What head should be used?

Yrs ago Tri-Point engineering had a few 25's in 3's....270hp w/ 220lbs of grunt.

Wow that’s not bad at all!

Think the motor is awesome, you should see the chassis & all the mods they did.

Would I run the 2.5 head or? High compression pistons?

I’m researching as much as I can get in but with the knowledge on this forum sometimes I prefer to ask directly.

I'd think you'd run the 25 head as your going for power.

 

[Luckyfd]

Thanks.

270 HP or WHP ?

My guess is they also were running ITB ?

What are you using this engine for ? Budget of ?

The build is only for fun. Budget is $5000 for the motor. But there’s some wiggle room if it goes over a bit. From what I read I can use the internals from the 2.5, upgrade the cams, use a different head or get machine work etc. where I’m having difficulty is to go turbo or stay NA.

 

[1turbofocus]

5000.00 wouldnt get you the 2.5 and a Turbo

So your thinking turbo on the engine you have or 2.5 NA swap ?

Tom

 

[Luckyfd]

2.5 NA swap. You’re right about the cost...

 

[Luckyfd]

Hopefully I can build a pretty decent NA motor for $5000

 

[Luckyfd]

Through my reading i understand run the 2.5 head and get machine work done. High compression pistons. What about individual throttle inlets?

 

[Luckyfd]

Clearly my original $5000 goal is out the window but it will be worth it.

 

[1turbofocus]

I would take a stock 2.5 , change the cams , add valve springs , adj cam gears and put it in all well with in your budget

Tom

 

[Luckyfd]

What stage cams could I run? Stage 2 crower? I will need to do the vct delete also correct?

 

[1turbofocus]

What will this be used for ? Daily

Yes , stg 2 will work , yes you will need to do the VCT delete and adj cam gears

This truck will be used for fun. Something to play around with
