Ditch the Carb and Go EFI with Holley Terminator X Stealth 4500 and 4150

Terminator X Stealth provides an old-school carbureted look with all the benefits of modern EFI. Available in both 4150 and 4500 configurations, these EFI systems can support up to 1500 HP, depending on configuration, and can control boost, nitrous, and offer many other performance features as well.

Yep, don't waste money or time with the sniper. Go straight to the terminator tbi unit, then when you're ready mpfi is a simple harness swap. The hp/dominator ecu's are well worth the money.

Do not waste your money on the Sniper Stealth with the ECU built into the throttle body. I learned the hard way that heat soak, RFI and EMF can destroy these units very easily.

So if this system controls timing do I still need a MSD box for an LS based engine? I was getting ready to purchase a carburetor and a MSD 6014, but I would definitely be interested in this kit!

I like how people ask questions but Holley fails to answer them.

Would you still use a wet nitrous kit with this or dry? (4500)

We need a complete 110+ high octane 4500 solution. Currently running dominator carb, 1000hp on the street. @Holley send solutions

Not sure why someone wouldn’t spend the few hundred dollars to buy this over the sniper. The External ECU is a no brainer to me.

How well does this adjust ratios when dealing with different altitudes? Say going from 5, 000ft to 6, 500ft and down to 3, 000ft. Is this instant?

How does it control the ignition, do you have to run hyperspark

[tommybletcher]

Suggest to buy the full kit its 3k and we are still waiting on the throttle body dont understand why the pushed it out over a month.

Between Sniper and Terminator X you pretty much have everything covered, now if only you could do a side draft Weber kit as well you’ll have the market cornered, all those 4 cylinder and Rotary guys will come aknockin

Can't work with s aggressive cam tho

[scottm]

It must be operating as a speed/density system. How well does it handle big cams and low idle vacuum?

I wish there was a conversion kit for the 90’s vortec truck motors. The stock injection system is horrible.

I play with an old car to escape the fuss of electronics and I’m 27. Stop
