FT-86 to be named FR-S...

Realistically, you cannot just bolt up a turbo to a block that was never designed to cope with forced induction and expect that it will last. What else is there to explain?

That IMO is the issue with a car like this. It's performance is great for it's price point, but if you want to go to the next stage reliably, it's going to come at some expense.

Umm, isn't Subaru running this exact engine with a turbo in the JDM Legacy GT DIT?

So I'd reckon that there's enough of a safety margin there.

Internally, it's different. From the info on your link, the turbo version has a lower (static) compression ratio.

But we'll see how things go, a little but of boost shouldn't hurt it.

Easily. Every gen 4 liberty that gets an upgraded rear sway bar, and anything more than 215 economybus tyres snaps the swaybar shackle mount off.

And the BRZ is identical to those.

And I use the AVO mounts on the gen 4.

And the AVO mounts have not broken, unlike the stock ones which snapped clean off the subframe.

Which are identical to the BRZ ones, once again.

Hope this helped. AVO = justified, due to 8 years of seeing the BP/BL liberty faults, and now GR impreza faults, and low and behold, what do you think the rear subframe of a BRZ looks identical to?

Front engine RWD car should not have a rear ARB/sway bar anyway, assuming that the weight distribution is around the usual for such a car.

Where did that theory come from?

[cracka]

From LSD/meth.

[IMOA]

Where did that theory come from?

It's from the sweeping generalisation school of vehicle dynamics

[260BC]

Context chaps, the topic is about a production model FERWD car, OK? My experience is with two similarly configured but different cars of my own on the track plus other competition cars that I'm familiar with.

Not going to argue about it but if you want to avoid snap oversteer no rear ARB is certainly worth trying, in fact it would be silly not to. That's if you go fast enough to get in such a situation of course, if not carry on

You really can't just say that. In your particular case, with your tyre/wheel combination(static & dynamic geometry), front roll stiffness, front & rear roll centre heights and and rear roll stiffness provided just buy your springs it works, but you cannot just say that applies to every production car suspension design because they are front engine rear wheel drive. That is ridiculous, any good chassis/suspension designers incorporate the use of bars (or some other roll device) so that it is adjustable within a functional range.

How much does the BRZ weigh? How much does a Gen 4 Liberty or GR Imprezza weigh? Might that make some difference? (F=MA etc)

The BRZ will have more weight over the rear axle than the imprezza as it doesn't have an AWD gearbox (and hence box & engine mass) set forward for front driveshafts.

Sweet double :knock:

[Justengt4]

the only thing i would be worried about is the fact its made by subaru. historically subaru arent known for over engineering their motors.

and justen.. would you have gotten that same power with boltons from a 1uz vvti?

Briefly, hell yeah

As for modern engines and ability to take boost...the ZZs seem to take quite a bit just fine, UR and GRs the same. Modern tuning and fuels mean it's the engines physical strength as the limit, as opposed to tuning det limitsas it used to be. Stock hp x 1.5 should be safe enough and provide worthwhile extra fun factor too

[myliberty]

Meh if it pops engines are cheap. I'll guinea pig that shit.

im sick in the head. But dfv's in the gen 4 are just stupid good.
