some turbo questions+

[darren23]

hi there iv got a 93 rs legacy converted to single running a tdo5. i was wondering about putting a twisted turbo setup on it. what the advantages and disadvantages and would you recommend one thanks

[lachlan]

the only real reason for a twisted turbo setup is if the turbo wont physically fit in the stock location . or if it has an intake bigger than what will fit under the manifold

yours prolly doesnt go under the manifold anyway

it doesnt offer any benefits other than fitment

Advantages

Looks cool, can fit a big ass turbo there, straighter intake.

Cons

F**king expensive. Need new / retunable / retune on existing ecu to be able to run it well. Time consuming to set up right, lots of custom work, extended oil feeds, altered water feeds (if applicable) whole lot of adjustment to i/c piping, and if a cop ever asks you to pop the bonnet, even with the stock turbo, you may get stung for uncertified car. Bearing in mind any turbo change or wastegate modification or even a retune / link ecu technically requires a cert.

cool thanks. im looking at putting a link in want around 350 horses what would be best way to acheive that turbo wise

[ADIKT]

Leave the turbo for now. Put the link in with like an exhaust/fmic/etc. Get a tune.

I would start with that then I would start thinking about bigger turbo n shit

Td05 is not a bad turbo.

The real benefit of twisted turbo is you lose the restrictive stock flexi and free up intake tract. You can do that with a stock size aftermarket uppipe and silicon intake.

I did a write up on pulling power out of ej20\'s in stockish form. Its in the engine thread.

Twisted only really required on 90 degree inlet setups. On the later model it\'s a waste of time. on 95% of setups a twisted in not required... post up detail of car setup is the best way to start. An ecu is probably the best bang for buck power mod you can get. Consider that before upgrading turbo as you can upgrade an ecu and have it tuned for more response an power but a bigger turbo untuned won\'t net the same gains and probably put the engine life at risk

oh an yes requires cert. I wouldn\'t let the cost or mods required be an issue. Any power upgrade will be time consuming and costly
