I got my 4jj1 remapped and a 3 inch pipe fitted. Making 200 and is absolutely fantastic towing. I've looked at a full build for fun but yeah bit hard to justify when it costs as much as the car :) One day maybe tho

And what stroker pumps do you have and aftermarket headers ?

@@danielthornton3277⁠doesn’t prove long term reliability. You can work the crap out of any motor. How long it lasts for after that work is done compared to factory is what I’m asking. Do we have them with 300 thou on them, have they done heavy loaded towing and still proving them selves. I know I can throw a blower on my Y62 and not have any engine problems up to at least 150k due to others that have been done, but I do know the transmission will shit itself due to the extra power, this has been shown on ones that have a blower, then it’s a 15k plus rebuild for heavy duty clutches etc

my 2018 dmax needs a new turbo.. if i fit a gated turbo, can you delete the vacuum control boost actuator and make the gated turbo work ?

Absolutely can mate! The 2018 model is similar to these and will require an adapter flit and exhaust modification like in this video but very worth while doing 👌

Hi just a few question. Is the stock turbo of 4jj3 is f44 already? I remapped already mine, the psi is 22.5 set by the tuner. Is it safe? What is the safest and the maximum psi of the stock turbo? Cheers!.👌🏽

@davidguiraudvieto 2 ай бұрын

Max turbo is 30 psi supposedly. I’m right there right now but ordering F44 and supporting mods soon. I felt what 35 psi felt like during the tuning and I definitely want more😂.
