Has anyone stroked there 2.9?

[1987ranger12394]

Was curious if anyone has used one of Tom manoras kits.

Talk to @PetroleumJunkie412 ... hes always stroking his “ego” when it comes to the 2.9L.
Seriously, if there’s anything about the stroker kit, he probably read it.

Waste of time. 2.9 is a flat power curve that likes rpms and boost.

Port it. Turbo it.

My heads are out for porting. Turbo is on mock up block with headers turned backwards.

These motors like boost and revs, not stroke and compression.

They build the f*ck out of these motors in Europe. Very easy to push to 300hp.

Harder to do, but many examples of 400+ daily drivers.

There used to be a member here called "elfasto" who was making a stroker 2.9 by using a 4.0 crank and rods. I dont know if theirs any sort of paper trail or evidence of it now though.

Ive never seen anyone run one of moranas kits so you would be the guinea pig, but for the price id imagine its good. But @PetroleumJunkie412 has shown its possible to get insane numbers from these little 177CI of fury motors, follow his lead if youre looking for speed.

I'll stroke it for 20 bucks.

Oh boy!

I can't remember anyone finishing a stroked 2.9. As PJ alluded to, it's kind of changing what the 2.9's good at. If a low RPM big displacement 2.9 is what you're after, you could get the factory version by going to a junkyard.

Absolutely correct. The 4.0 ohv (my second favorite rbv engine to beat up on) can very easily be built into a low and slow torque monster; think of them as a V6 version of a 390 - low rpm lover that's torquey AF in low revs, with minimal upper rpm power.

Fantastic engine, but has many of the same head issues as the 2.9.

If you want flat power across the board, low boost 2.9.

Ass tons of low end power? 4.0 ohv.

Beat up on by all of us? 3.NO.

Only one I'd NEVER recommend is the SOHC. This thing feels more like the 6.2 every day. Pig at low rpms, pig at high rpms, very difficult to keep in its power band unladen.

Colognes are WEIRD engines btw. There's a lot of of different ones in the family, initially V4 and V6, and thanks to Aston Martin, now V8 and V12 variants. Displacements options ranging from 1.8 to 4.0 for V6 alone. The 2.6, 2.8, 2.8i, 2.9, and 4.0 OHV versions sharing much in common, and the 4.0 SOHC and 2.9 DOHC as the weirdo versions.

Lots of options out there, and with so many block and head choices, you can basically build whatever you want out of them.

Now if I could only track down an Aston 6.0 cologne...

I might be a pig... because the SOHC fits my driving style.

Pretty sure the Aston V12's are Duratec based.

I'm glad it's not worthwhile. I really didnt want to spend 4k on his kit. I guess I'm back to looking for a reman block to put forged parts in.

Well, DCinDC proved that the stock guts are strong enough to run 17psi without issue.

My waste gate is set for 8psi, cast internals.

I priced out forged guts. Not worth it in my opinion.

Burton power in the UK does stock them if you do want them.

Do you have a copy of the Pruett book yet?

 

[1987ranger12394]

I do have a e copy of his book I plan on ordering a hard copy.
I found a supplier for a long block with hypereutectic pistons,Moly Rings,Brass Freeze ,RV Camshaft,12 HP Valve Springs (RECOMMENDED for use with RV Camshafts),ZDDP Additive,and heavy duty heads. I'm not sure what stock comes with but if that's the strength of stock building a 2.9 just got a lot easier.
