Titan Stroker Engine or a Better Option?

[FadeToGray]

Anyone have experience with the Titan Stroker engine?

Looking at it versus their regular HO version.

Although the extra power would certainly be nice, reliability is more important.

Or is there a better option out there? I've used Jasper engines / transmissions in the past and have had bad luck with them.

Thanks in advance!

Golen or Newcomer if you're looking for more power

I think Titan will be fine. The price is comparible to Golen when you put it all together. These are pretty mild strokers. While they aren't shattering any HP numbers on the bench, the increased area under the curve will noticeably change the way it drives. And they're reliable, but prone to leaky rear main seals as are every other 4.0L.

You can alternatively source parts from folks like Bishop Buell Racing, Clegg, etc.

S&J makes a stroker.

Build your own. It's not terrible but I think it's more expensive than buying one.

I’ll likely go with S&J for a replacement 4.0L, but iirc their stroker is built for 87 octane (also known as a “what’s the point” build).

Have you looked at gas prices these days?

Have you checked the math between running 87 and 91 for a year?

hahaha ... fuel prices are so bad I had to park my diesel truck and drive my TJ

Yep, $5/gallon here.

Wife's little Fiat wants the fairly rare 91 octane. It'll run on anything, but the mileage drops significantly on lesser fuels.

I will say that I'm getting 17mpg on my 40-50mph daily commute. That is based on GPS mileage, not the odometer. That said, I have a n LS in my CJ5 and there is no way that I'll upgrade my 4.0. I'll immediately swap to another LS. I was getting 15mpg on the same commute with the same size tires and no overdrive.

Does the baby Fiat have knock sensors ? If so this makes sense , it will run on regular gas , but it has to dial back the timing to prevent knock , killing gas mileage . My 96 S-10 262 would pick up enough mileage to run premium over regular gas like 3 m.p.g. plus run stronger !

Yes. You can run it on 87 or 89, but it doesn't get as good a mileage and my wife says it runs like a dog. The problem is that most gas stations around here have 3 grades, 87, 89, and 93. The 93 is, of course, a total waste. Most - but not all - Sunoco stations have 91. There's been a time or two I've tried mixing 93 with 89, but its mostly an exercise in futility.

That's because gasoline octane ratings are not made by proportionally increasing the same additives. And it doesn't want only 91. It wants 91 or higher.

Living at high altitude, our top grade premium is 91. Our regular grade is 85. That's part of the reason it says run 91 (or higher).

That's common for most of the competition. They run something equivalent to a Clegg stage 1 with a larger dish. I find the popularity of that build a bit odd as it leaves alot on the table for modest annual savings. Figure $100-$400 a year for someone driving between 5k and 20k per year

I understand that. I don't want to pay for "or higher". So I'm trying to downgrade 93 by mixing it with 89 to get 91.

Have you looked at your decrease in mileage vis a vis the increased cost of the 93?

That's why we just end up running the 93 when we can't get 91. Wife says its "terrible" on sub-91, but no science has been applied.

You're not really understanding. The additive package for a premium fuel is different from a standard fuel. Mixing the 2 at say 50/50 is like mixing synthetic Motul 10W30 with conventional Quaker State 5W30. The additive packages may not play nice with each other and you definitely won't end up with 7.5W30

Yea, that may be. I don't even try anymore.
