Ka24det build questions
So I am currently building a ka24det.
I will be running: Cp pistons Manley rods Bc springs and retainers Bc valve guides Tomei 270 poncams Tomei adjustable cam gears Xcessive oil pan with baffled sump 1000cc injectors Radium top mount fuel rail Warlbro 430 lph fuelpump Aeromotive fpr RS Enthalpy rom tune Mazworks z32 trans conversion Z32 maf Now heres the question. I currently have a gt2871r with an isr exhaust manifold but i strongly feel as though this is going to be a rather dissapointing turbo setup. Now im not looking at completely breaking my bank with a new gt3076rs so i will most likely be running a twisted motion gt3076r. Now my current isr manifold is a t2 flange and the 3076 is a t3. Im already going to have to get an elbow fabricated for the exhaust exit flange but what is a good reliable t3 manifold that is not going to break my bank, or would it be worth getting my isr manifold modified with a t3 flange. This has been driving me nuts for the past 3 days and as it is almost time to send my block to the machineshop. I need some input. Sent from my SM-G930P using Tapatalk |

Don't buy a twisted motion turbo. They shit the bed all the time.
If you can find an RB25 bellhousing, they bolt up with two holes dremeled out a bit. Add a Cosworth headgasket to the list. If you're going to make 400wtq or more, you might as well add some 11mm or 12mm headstuds to the list, the 10mm little guys can only handle so much. GT2871r is small, will light up quick and produce a huge torque hit. This may be desirable to you, but if longevity is your goal, slow the spike down. IMO fuck the MAF and go nismotronics and speed density. I understand if you don't have a reputable tuner in the area though. That can be a big hurdle.

OP, you never stated a HP goal, but seeing your engine/fuel/transmission mods you probably want some serious power? If so then ditch the bottom mount turbo setup and go top mount tubular with a turbo t3 and up.

I'm actually considering switching my ka-t top mount t3/t4 setup to a bottom mount 2871r and a tomei manifold. Should net close to 350-400whp with a great spool and torque curve. |

Find yourself a used GTX if you're sticking with bottom mount, if you're going top mount and want something cheap get a Holset.
