    What's the current state of the Turbocharger Nation?

    So, having been out of the buying-4-cylinder-turbochargers loop for a long time now, and being outdated even then, I have been plotting on using the pair of T3/T04B turbos stashed away for the Maverick drag motor. But, I had an opportunity to sell these on and not loose any money on them...off they went.

    Now, I had 730$ in the pair of turbos, and came out with that much after. It's time to buy some replacements. The engine is the 5.0L inline six, and for packaging reasons, it'll get a pair of parallel twins. LS1 heads, custom this and that, you know the story.

    Essentially I want to know what the cool kids are running in the 2.5L 350-400HP engine club these days. The manifold parts bin has a pair of stainless T3 flanges, and the largest housing I can easily make fit without heat/pipe/packing issues is 9"/230mm across the compressor housing. I could cram a 10" housing in there if I were to swap front suspension or squish the charge piping around.

    I'm not sure of the size, but I think the new G25-550, or G25-660 would be pretty good for that target. Or the EFR 7163, but i think its a fair bit bigger.

    They're pretty current "high tech" turbos at the moment in that power range.

          Anything is better than the t3/t4 you had.
          Mamba gtx3071 would be good on a budget.
          G25s are great but near on 3k each aud.

            Mamba turbos are kinda hit and miss

              your budget is pretty important here as there is a huge spread in cost.

                I'm hoping to spend 600$ each or under-but it's one of those things. I'm re-making motor mounts this weekend to adjust the tilt on the engine a bit, which will give more room on the turbo side of the bay and help with oil drainback. Once that is done, I'll be able to get more concrete dimensions for what will fit in there.

                The old T3/T4 turbos were supercheap, but I knew they weren't the best junk available...just the cheapest. Things are a bit less budgety this time around.

                  $600 and current hotness are not going to play well together...

                      $600USD each is plenty.

                        I don't have to have the top of the line-but I am sure there are better turbos than the T-series stuff I had before.

                        Right now, I'm looking into the 46mm BorgWarner S246SX, the only inconvenience is the turbine housing's T4 flange/T3 inlet.

                          Internal gate? Spend more on turbo and less on gates?

                          Or external gate v band.

                            I bought a gtx3076 for a 1jz and it was great, 280rwkw on 16psi; Foamy bought a gtx2863 for a ca18 and it was rubbish, made absolutely no power, swapped it for a borgwarner EFR and it made bulk horsepower. He had it looked it, nothing wrong with it, just inefficient as fuck. Further to that, know of a few people who have tried various models on EJ20's and reported the same, junk.

                            They seem reliable but some of their in house combinations just don't work.

                              Weird, I use GTX2863 on 86 turbo kits and they work fine. Make 220kw atw on e85 at 10psi.
                              If you said you swapped the mamba for a Garrett and it worked better there would be something to suggest an issue.

                              A filthy old shitbox CA18 probably has a very small window of turbos that actually work.
