Hi all, want to replace my current cheap europarts ignition coil on my 144bhp ERST not sure im getting a decent cold start spark.

Should I get a group A coil or is this a bit unessasary

or a standard bosch coil? http://www.burtonpower.com/bosch-blu...221119027.html

and.... do I need the little ballast resistor?

Thanks in advance folks

 

I recently got a group a one on email for 15. Bolted in but not tested but it seems to get good reviews on a number of forums

 

Thanks simonmcf, yeah seen some aswell but usally quite highly moded cars
I would get one but you have to get the loom aswell so for the sake of just spending money after money do I acually need this or will the bosch coil be more than enough

cheers

 

std. coil will be fine,and alot cheaper!

 

I've had a Magentti Marelli group A one on my ERST for several years an it's still going strong. Was only £7 more than a bosch std replacement and there's no loom for them, you just change the connectors to spade. They'll even fit using the original bolt holes.

 

The loom is just a rely that is triggered from the original coil wiring which then switches a feed direct from the battery to the coil. That way you no you have good voltage at the coil and not power going through old wiring that could have a resistance in it

 

Thanks for your replys folks, think i'll go for the grp a with a new loom

Thanks again

 

No harm in that.

There is no point going with an aftermarket coil ; I have had no end of trouble with them, often giving me more issues than when I had the original item on?

However, check your wiring and ensure that you are getting 12V at the coil.
