    Ok, that is still a good sized housing.

    Finally making some boost before 2k. Fuel map is rich, but that's better than lean. 2 psi before 1900, 5 psi at 2250, give or take. Kinda depends how much skinny pedal at what rpm or it just drops a gear.

    I feel like I guessed pretty well. That is very impressive!

    Now the next question is, will cruising over 2k mean that you're in boost or no?

    Cruising is fine. Drives like a normal truck. It's not the Rpm, its load. So towing, uphill or head wind could put it in boost. Too soon to tell, but so far so good.

    Gonna be the ideal A/R really for this. Be super street able and fun. which it looks like you're finding out.

    2" for increased velocity/faster spool.

    2.25" if you're going for just a HP queen.

    Id go down to .81 A/R at least as well, aren't you twin? Or is that a different guy..

    Bw s256 turbo with 3 in glass pack dumped pre axle raptor liner bed and top rails and fenderflares and rocker panels. Hunter side steps. Plasti-dipped upper fenders and emblems. satin black spray paint here and there inside and out. 5100's set to 1.75" up front . C channel front bumper. Maxxis bighorn 255/85/16
    I'm also throwing a vote for 2"; a lot less "stuff" you gotta make room for with the smaller pipes and it will be lighter and gas velocity will be higher and you can weld 2" faster than 2.25" haha

    I’d like to be twin, but don’t think I’d ever spool two 9180’s lol.

    There might be a smaller A/R for mine, but if memory serves somewhat accurately, it is only in a T3. Being that I don’t have that kind of housing, it rules that choice out.


    Oh yeah, well aware. Just getting a mental comparison between your setup and how quickly it spools, versus the story of my friend’s with his smaller sized turbo on his 1GR. Going off of rpm because I cannot remember where an XR runs in vacuum cruising, between 2 & 3k rpms on level ground.

    Also reminds me of a conversation with an engineer from Both Warner. They were working with a drag racing team. Maybe Australia? Twin 9180's. At idle the turbos were creating 1-2 psi! I digress. My 4 liters of fury still needs the load plus 3k to make the choo choo sounds happen.

    Speaking of which, after correcting my VVTi map the other day, my engine is much more responsive. Including spool time.

    Why did you go with such a big turbo?

    Is there any interest from 2nd Gen 2TR guys for a billet valve cover?

    Because everything is built for 1k+. I take that back. I still need to revise the fuel system. That Walbro 480 isn't enough.
