As above.

 

Diesel

 

Used to run mine on the good unleaded stuff

 

Probably make mine run better to be honest TT

 

YYeah ran my last one on it too. Should the timing be changed.

 

Don't think it should, why whats wrong with yours?

 

Nothing mate. Is my new RS not even driven her yet, engine going in this weekend just seeing if many ran on unleaded out there.

 

eye c

 

super unleaded ONLY !

 

Only if it is chipped

 

deffo NO lrp ,,,, its horrrificaly crap

 

TT - What u can only use it if chipped or you shouldnt be using normal unleaded if its chipped.

 

Super Unleaded!! regardless of wether chipped or not - RST's were designed for Leaded fuel orginally (Last of the turbo's actually stated SUL in the brochure once 4* died a death), LRP no good. You can use NUL only if you have the timing retarded (assuming late head)

 

Yup

 

As per Billabong, chipped or not should run it on Super unleaded only to be safe

 

Not what my mate Chris says

 

Doesnt MR Norris do Lean Burn Heads

 

Optimax is the way forward

 

you mean MY mate chris

 

Your mate Chris is wrong then

 

no reason you cant run one on 95ron tescos shit as long as you get it set up on this fuel.

notice how when you loosen that bolt on the right hand side of the engine you can actually TWIST the distributor this beleive it or not actually does something

 

 

I thought everyone used optimax

That's what i changed to when i couldn't get LRP anywhere and it runs much sweeter

I'd recommend it

 

Lol so did i or super at least... dont understand why anyone would want to run an RST on NUL unless your a cheapskate or bought the car for its looks not how it goes

 

Always user super, stop being a cheapster Lee and dont use crappy unleaded, mines not chipped but still wont run it on shit

 

When I'm referring to NUL (95 RON) and SUL (97RON or greater) I'm not referring to brand, but grade of fuel i.e. either 95 or 97+ RON. I find it surprising, and a little disturbing that people think a standard ERST should use 95RON fuel!

 

Well i'm afraid it don't know my NULs from my SULs

 

Not a dig Kev, just clarifying

 

No bother, it's asking daft questions and sayin stupid things where i learn most stuff on here

 

Cheep stuff in my every day car and supper or optimax in the other

Cheers

just relaised we all completely missed the point of this post

a SERIES 2 RS TURBO has hardened valve seats so does NOT require leaded fuel/LRP/Lead Additives

ie you can run it on unleaded fuel without risk of damaging the head

i THINK some of the early S1s might not have this done, but i dont know for sure (ive forgotten )

also LRP is SHIT far better off using unleaded fuel + lead additives

 

Or Optimax?????? Am i right?????

 

Speak for yourself Jimbo ALL RST's were mapped to run LEADED fuel, or when that was all but phased out in normal use, SUL was deemed acceptable without further adjustment (in actual fact, 98RON unleaded fuel - people often forget that SUL used to be 98RON in the good old days....). You are correct about the valve seats, but that's not the real issue

EDITED: spelling

 

Billabong you know far too much about this sh*t

 

Probably

 

As Billabong says.. 100% SUL

 

My old S2 always had super or optimax and same for the RS2K

 

isent there 2 wires u can earth out what retards the timing in the ecu???????

 

That's on a Cossie (and some Vauxhalls) Gus, pretty sure you have to do it via the dizzy on an ERST.

 

could ave sworn the erst had them aswell
