Hi guys and girls, was just wondering what chip u would recommend to use for the ERST...the engine is currently COMPLETELY standard (even running standard hoses!)...however will be ordering a GRS intercooler and a chip soon...

the turbo and actuator are in good condition and the engine has done around 60k miles!

on the cards for the engine is the following:

stage 3 head
low comp'd bottom end
stage 3 turbo
piper 285t2 cam
GRS intercooler
ARP bolts

thats about it.

would the above spec change what chip i need? or doesnt it matter?

thanx in advance

Hmm... Good question. I run a collins performance one in mine - it has no boost limit and seems to fuel the car fairly well - but I haven't tried others so can't make any comparisions but heard Ahmed Bayjoo chips are good.

 

the thing that is putting me off the stage one Collins chip is the 14psi boost limit...

need something that takes more boost

bassboy

 

The collins one i've got is their unlimited boost one - so will run anything. It might be a case that it overfuels slightly with lower I.e. under 14psi boost levels but you have to make some kinda compromise i suppose.

 

Hi mate I've got a chipped ecu if you want it, there's no boost limit and mine did 172bhp with that chip and a k+n, its Collins I believe

 

NMS or Turbosystems

I wouldnt go for an off the shelf stage 3 head,apparently they flow well on the bench but not the car!

A piper t2 cam would also make the car way to laggy.

Speak to Karl Norris about doing a head and cam to your spec,it will make a huge difference.

Trust me

 

i got my chip from m a developments i told mark shead what i had done to it and he got ahmed bayjoo to make the right chip up im running 20psi boost and 221 bhp its cool

 

ALRIGHT TREY, DO U GO MIKEANICS IM FROM MOW COP. I WORK AT BURNS IN CONGLETON. JUST WONDERING IF GO THERE AND ARE THEY ANY GOOD. CHEERS

 

cheers for that everyone...but the deal on the van fell through unfortunately really liked it to!!!

will be looking at a S2 tomo which has been modified but im unsure how far...guy is claiming 200+bhp but will have to see proof!

oh and BTW, wildheart...howcome a stage 3 head doesnt flow as well on the car? also what are the down sides to the piper 285t2 cam? i heard a standard cam does VERY well...?

bassboy

 

Gaz, yes mate I do go to Mikeanics, and He's good as far as tuning goes, but I've got an MF2 on mineand unforunatley it needs to be live mapped, ie. while being driven on the road, which I don't think Mike does, but for everything else he's good What car you got mate?

 

Dont know why stage 3 dont flow as well on car,im no engineer

Best to speak to karl norris.

Karl also says a new standard cam is very good

 

From what I know, seriously ported heads flow the best but create more lag, I used to have a 285t2 in mine, which was fine till I put a stage 3 turbo on it. The combination gave me huge amounts of lag, and I do mmean huge, all the power was between 5000rpm and 6500rpm, I've changed to a 285T and its alot better

 

I've got a S1, my mates gotta a blue R5 gtt RAIDER, seen him about??? he's seen u around macc....

 

The only raider I can think of is a navy one with centre exit, if thats not it I'll have to keep a look out for it

 

I'd agree with Trey bout the t2 cam and stage 3 turbo causing loadsa lag - cos that was my previous spec. The new lumps still got a t2 cam but using the ceramic bearing turbo really has made it work well - just pulls and pulls now
