V7 STi vs. V8/9 STi

[Sudo]

Howsit, havn't posted here in a little while, but looking at getting back into the Subaru game.

I'm looking at a V7 STi at the moment, blue, tein adjustables, Defi gauges, etc. Quite a nice car.

But I just wana know how much better are teh V8s? Other than cosmetic. I know they have a different manifold, and VDC, but what else makes them better?

Bit of a noob with the newer WRXs

Cheers

AFAIK they don't come with VDC

V8/V9

Better due to twin scroll turbo + headers

make abit more power - spool up abit faster

V9

Better due to Front LSD

Downside -- heavier than ver 7 + don't have forged pistons

Didn't NZ new get LSD fronts?

i driven the 8 last week i was surprised how well the turbo kicks in just because of the exhaust mod, now hes got a front mount cant wait to see how that feel. hes getting the ecu refresh soon.

the hubs on the 9 are better also

some 8's come with lsds in the front by my research..

the v8 got the suretrac front lsd and the helical came out in the v9

[Pappu1]

for the $, go the v7.. the 8 is smoother and more responsive due to twin scrol , 9 is same but better handler slightly

altho u lose the suby rumble on the 8/9

if the sound was important go the 7 easy..

NZ new STi 7 came with Suretrac front lsd, better than an open diff but not as good as the V9's combination of fancy helical front diff, auto DCCD and active yaw sensor, all of which turned the V9 into a nice Evo 8 clone.

Bigger 235/45-17 RE070's on wider 8" Enkei wheels helped too.

Overall a V9 is a much better car than a V7 (unless its a V7 STi RA Spec C)

haha you bet me to it, was going to mention that the newer is better, unless of course it is a V7 STi RA Spec C

I do like the subi sound, but my mates got a V2 RA with tuned headers, sounds pretty nice also.

I prefer the 8/9 headlights, but for the extra money it's not worth it to me

[WRXER]

It's easy enough later on to facelift the v7 to a v8/9

Spose i better get in quick...

My old one came with Suretrack front, DCCD and had a nice CUSCO LSD...

My vote would be:

V7 if money is a concern, V8 if not as you will have a better selection of wheels and suspension available over the v9(before they changed the shock mounting and PCD).

...or, if money and taste are not a concern, buy a new one... ;D

[Sudo]

Money is a issue haha. I'll only be able to use what I get from the RX7, so around the 20 mark, once I pay off some debt.

Is it the 9's they went to 5x114?

[Simon C]

V8 had twin scroll, softer seats, front facelift, mild changes to the interior (gauge cluster and steering wheel) and DCCD over V7.

V9 had Spec C front suspension geometry, 5x114 hubs with wider track from wider wheels, Bridgestone RE070 standard (vs RE050), yaw sensing input to the DCCD, flared rear arches, interior facelift.

My one has a Suretrack front, viscous centre and mechanical (? helical) rear LSD.

I thought they carried the V7 Spec C front suspension geometry over to the V8 STI?

[Pappu1]

na they went to v8 same as v7 ..the 9 get the c spec setup

thats what i thought eh.. v7 spec c got put in the version 8..

then the version 8 spec C got put in the version 9

[newsuba]

pappu ftw

[EJ20T]

as far as i can remember from the best motoring DVD i had, the ver8 sti got the increased wheel base (extra castor) the ver7 sepc C got. for ver9 they just added a yaw sensor to the DCCD and increased the track and upgraded the hubs. ver8 also got the RE070's standard, not that they will have them buying second hand.

PS torque was up'ed

ver7 384nm

ver8 392nm

ver9 412nm

[newsuba]

Only v8 Spec C got the revised front suspension.

Std car retained the 2525mm wheelbase of std V7 STi.

V7; wheelbase 2525mm, track f/r 1490/1480mm (hatch 1465/1455), 206kW/373Nm

V8; 2525, 1490/1485, 206/394

V9; 2540, 1490/1495, 206/412

V10; 2540, 1490/1495, NZ 2.5L 206/392, JDM 2.0L 206/422

Figures from official Subaru brochures etc.

[Pappu1]

hahaha soory man but all the little changes subaru makes to different versions is toio bloody hard to keep up with..

bah .. they even had 3 bloody reversions to a single v7 so who knmows what other tits and bits are changed

V7 Spec c wheelbase was 2540, extra 15mm increase due to castor angle change...

Was sure this caried over to V8 sti, but, guess not...

[funkytown]

the the v8 spec c did get rolled over into the v9?

[EJ20T]

also changes made to the rear diff between ver8/9 but im not 100% on the details, also they added a small LSD to the DCCD unit, that reduced the maximum torque basis to approx 60%

[vee7_sti]

bang for buck id go for the 7...you can get some nice ones privately for around 16. i just got one, and yeah, its a bit tamer than my mates v8, but it still pulls nicely though. and of course you get more of a rumble with the single scroll, if that means anything to you lol
