How necessary is the Downpipe?

[suicidaleggroll]

Let me put it this way...if the downpipe didn't make a difference, tuners wouldn't be making separate maps for stage 1 and stage 2 with different timing and boost targets. They don't make different maps for intakes, charge pipes, catbacks, etc., but they DO make different maps for stock vs aftermarket downpipes. That should tell you everything you need to know.

Ask Luis. lg_supra on instagram, he's really kind, i'm sure he'll give you whatever answer your looking for.



Honestly, I'd looove to hear more about this one. Did you run it at TX2K a bunch of years back? There was a sick 70s celica (i forget the year) with a 2JZ swap and 80something mm turbo. Thing was a beast.

I'm not sure why I didn't think of this earlier, but where's @Marshall@ViscontiTuning? I'm sure he knows more about this than @Mason and I.

No I was in my R32 GT-R the year that car was there (the celica that sheared the wheel studs on the line). That car was a 6 speed Getrag 2JZGTE setup. Mine is a fully forged LS 6.0 with twin 66mm, TH400 and Parallel 4-link. It's a liftback 77. Still working on cage fab etc right now, but the engine is in the car, I built new subframe, rack and pinion conversion (with electric power steering), full front mount IC setup and turbo piping is all done. huge project, but the back-half is almost done and it should go quick from there. I do everything in my shop myself (aside from engine machining and balancing). I do all my fab, Tig welding, engine building, tuning, etc. I can post pics elsewhere really.

If that is directed towards me, I really have no desire to argue with you about what I posted. It's all accurate and proven many times over.

I replaced my downpipe with an uppipe - much more effective

I ran one for a while, then decided to try a rightpipe, but the car's radio kept cutting out. Had to remove it.

Did you try a leftpipe?

I don't swing that way, buddy.
