Sequential Twin-Turbo Setup Question

[jojothemonkey]

I have done some searching on this topic (Sequential Twin-Turbo) and it sounds appealing. I think I may have read somewhere that the steering column (?) might be in the way of the second turbo. Anyway is this a feasible idea? If so would this require any major modification to the engine bay? Like I said, sounds appealing.

appealling for the ooooh factor
on KA or SR?

ka i know hits steering shaft/brake mc
SR its been done but you'll run into same issues. if its RHD you'll have more clearance

no reason for TT SR or KA

[jojothemonkey]

ooohhh factor is always a plus but I am more intrested in the whole performace factor. It would be for an SR.

You are dumb. Please change your username. You disgrace jojos and monkeys all over the world.

haha
performance factor?!
gp sports had a tt setup on their S15. it was on there for a bit and then removed. no reason for it.


research more on a TT setup on freshalloy.com

one member on FA (Enthalpy) pushes 440 Hp/345 tq - 18psi w/ a single turbine on a SR. hmm. that's performance!

tt setup on a SR is POINTLESS
do more research and you will learn.

Thats nice

I was just kidding. Ok seriously. If you can't figure out a way to plumb sequential turbos in an S-chassis engine bay, then you shouldn't be considering it anyways. I also don't think you did enough research because if you knew anything about the minimal benefit vs. time/money/complication, you wouldn't be considering it. Use a properly trimmed turbo for whatever application you intend and enjoy your SR. For the time and money spent on fabricating a sequential turbo system for SR, you could easily blow it away with a single turbo and half the budget. So since performance is out of the picture, the only REAL benefit of sequential turbo is bragging rights and bling.

Ahem, ruf its Bling Bling... see there's 2 blings in there! not just the single... i would appreciate it next time if you got that right ok?

Nonono. It's sequential not twin. So it would be bling...BLING.

since most people who modifiy the 2jz supra motor take off the two turbos that come stock on replace them with a single turbo, that's enough reason for me to run a single turbo. Also, they have 2 groups of 3 cylinders, which hopefully you have found out is a good thing.

That's twin not sequential.... I was under the impression the reason for both of these setups was to reduce spool up time. For drag this isn't really relevant, but for track racing, autocross and general street use twin or sequential turbos can certainly create a more useable powerband.

you forgot it can also add weight... just size your turbo correctly and you will do fine. for the money it isnt worth it.

I guess it just depends on what you are looking for.

If you (jojo or whoever is a fan of sequential) use full-throttle alot below 3000rpm then you probably need something besides a T3/T4 on a KA or SR. However, in my opinion if you want to go fast you should never, ever, be below 3000rpm, unless you have to launch below that to avoid roasting the tires. If you feel the need to use full-throttle below 3000rpm and can't downshift for some odd reason, then you need sequential turbo stuff. If you can then you don't simple as that. This easy to drive nonesense sounds like driving harleys or mustangs.
