Hi all, has anyone got any links of a good ref site between the two. I tried searching on here and it goes on about ecu's etc but basicly looking for age range rareity engine details transmision details, chasis differencesn basicly what's best. Owned a cossie for 8 years but no nothing about s1 and 2's. Cheers in advance. Luke

 

S1 is better but you will pay more.

S2 is softer but cheaper.

Series 1 is ace. Series 2 is ace. I prefer 1's but apparently 2's drive better. They have different turbos. 2's are water cooled 1's arent. Gear ratios. Anti roll bar set up. Even think there are slight differences inside the engine too

 

Cheers fellars will look into it, had my cossie 8 years so I've ignored the rs turbos up untill now so I got a lot to learn. So will s1's hold there value better? What size turbo do they run? I guess the s1 is oil cooled and the s2 is water cooled. What sorta speed are they as standard??

 

Both will hold value but s1s will shoot up soon

 

Why will they shoot up? Is it same as saphs more are being broke? How many s1's were made then? I tried to research turbo on s1 but all I could find was turbo on a s2- T3

 

Both have t3 turbos but s1 has no water cooling, as said anti roll bars are different, s1 has no gearbox cradle and shorter gear ratios, s2 is a bit more refined

 

a lot more than you think,
parts different are,
loom,
dash,
doors,
lockset,
kit,
wings
glass colour
mirrors
rear panel
engine block
gearbox
front anti roll bar setup
rear brake compensator setup
smaller clutch/flywheel
all dash brackets,
bulkhead sound deadening,
interior
abc pillar trims
bootlids different as mk4 is recessed round the lock
bonnet obviously,scuttle panels different
brake crossover bar on s1 are smaller
brake servo/master

kjetronic setup is different too only 1 sensor on inlet manifold,
inlet manifold splits on s1
no abs
washer bottle
header tank
electronic dipstick on s1
floor numbers in a different position

loads of other differences mate

 

Did you look at my links i posted? these answer your questions...................

 

Yer mate but the page didn't answer any of the questions I just asked$ apart from speed.

 

S1 have racing pedigree and were designed for racing in mind. They were produced in a short production span than the S2 were(The S1 during the later years of the MK3 production) the S2 was produced from the beginning of the MK4 production until the end of the MK4 production.

The S2 was designed for fast 'road' use and with this in mind the suspension etc were designed as such.

 

From research it seems u can't gain big bhp with ers compared to cossies. What the biggest u can go on standard engine injectors etc. Just with a chip. Like stage one on a cossie??cheers
