you can have a turbo make power low. like said, they are just reading at 3k and up. a factory sti boosts pretty low, you can have boost pressure and torque at about 1500-2000 RPM if you wanted...it just takes the correct setup.

since the fr-s revs higher than a normal subaru would, i would rather have a well performing mid range-high end turbo. boost by 3k is awesome.

Love the new STI turbo. A friend of mine just got a new one and there is no lag whatsoever. It's great for this area of Colorado.

Twin-scroll anyone?

Am I the only one that kinda likes turbo lag?

In my Supra, I didn't get out of vacuum until about 3.5k and I didn't make all 21psi until about 5k or so (IIRC).

I LOVED how docile the car was in daily driving. No whistling, no blow off, no drama. If you wanted to boost, you dropped a gear and away you went (It was a BoostLogic Auto, so that was as easy as putting your foot down). It was great for sneaking by police, sneaking by Civics (:D), and sneaking by the president of the homeowners association coming back home late.

On top of that, there's no surprises when going from light to light, because you're head doesn't get thrown back at 3k RPM. If you had a system that made boost that early, you would be in for a jerky(ish) ride.

And of course, if you go to a track or a drag strip, you'll be kinda out of puff in the top end if your turbo is sized and set up for power early on.


But, there's twin charger setups... :bonk:


Just my $0.02.

Err stock turbo Supra makes like 10psi at 2krpm?

Considering he said BoostLogic Auto i doubt it was a stock turbo on that Supra :party0030:

A stock TT Supra running sequentially might start spooling at 2k, but a big Single sure doesn't! ;)

Yes, yes you are. You are the only one <Jeremy Clarkson>in the world.</Jeremy Clarkson>

Read my mind! its like mechanical foreplay

I think its a supra owners thing... Ive actually been thinking the same thing. If the car feels like stock power until 3-4k thats fine by me as Id prefer it to be very docile until you slam on it.

I wonder if everyone that prefers the lag feeling also likes the quote to walk softly but carry a big stick :0

I can't say I've heard that before, but I like it!


Perhaps it is a Supra owners thing...

Other sources have said the heads were developed by Toyota/Yamaha, just like in previous Toyota engines. And its been known since before the car was released.

I can't think of another subaru motor that had a head anything like the FA20. The head was co-developed by Yamaha/Toyota and Subaru, but the design features are definitely Yamaha.

You are simply making things up, I challenge you to give me one RELIABLE source. And this is not a 'previous Toyota' engine... the car, as a piece of craftsmanship, is a Subaru.

Yahama involvement was nothing but an old-school rumor. :thumbdown:
