High Mileage + boost

[kissrocksforever]

I have a feeling it's probably a really bad idea, but here's what I'm wondering.

160k miles
stock 94 5.0 bottom end
Want a kenne bell
Aiming for 400 RWHP


When added together does this equal boom?

yay or ney?

I'm also considering a forged 347 shortblock good for 800 HP, but thats an extra $2500 minimum.

The engine feels strong, and currently has no issues. No burning oil, etc.

Boost it.. Skip the kb

confused.

won't hurt a thing,when you do it go ahead and replace all the gaskets on the engine because boost will push shit all out around the old worn out ones.

confused.

Im guessing either turbo or a centri supercharger.

I think that combo at 400 is a ticking time bomb

You'll be fine.. We boosted a few over 200k and lasted a few years till we cranked it up to 16+ psi the most made on stock bottom end was 618 rwhp in my buddy fox with 219 on the clock, ran 2 years and to 264k before the rings went.. So as long as its not smoking and has good compression, does good on a leak down test, your good..

Now 618 was just for a glorified single dyno run in 18 psi on a master power t70.. After that we kept it conservative at 506 or so rwhp and 11-12 psi..

Centrifical or turbo kb is cool on mod motors were they can intercooled...

It's honestly all in the tune and the way the owner drives.

To OP, I say go for it and run it till it blows. Then go bigger.

Agree with that. Like forcefedhatch posted it's more about condition than mileage.

Do you compression check first. If everything checks out then your good to boost it. You can throw on a vortech S Trim for cheaper then a KB and the KB do seem to be aimed more for the mod motors.

i had a 178k miles on my foxbody and pieced together a turbo setup just too see what it would take before she went.........drove the car on 9lbs for 2 years and never had a problem......actually only pulled the motor cause i wanted a 351w so i say GO FOR IT!

 

[silverv6]

Im thinking the same.. 157k with a vortech on 5-8psi.. completely stock motor i have one in the garage im building for boost although.

Exactly, some people dont seem to understand this.
and buy a KB for their pushrod engine because the whine of the KB "sounds cool" lol



Op as Venom stated, do a compression test and go from there.

any car without a built bottom end IMO is a ticking time bomb

Im building a fully forged monster but in the mean time if i put it on everything would me done minus the motor swap.. ac relocated guages and wires ran belt ran etc.. But have a feeling its a bad idea

y is that a forged piston or rod wount keep your block from splitting... I think a forged assy in a stock block is a waste of money.. If your block lets go you just wasted all that money...

If you use the right combination of parts and tuning, it should be just fine.
