HT leads or Coilpacks for 96 Classic?
Hi guys, I'm slowly getting my new 96 Classic wagon sorted after some idiot I bought it off made a pigs ear of everything. I've replaced the nasty manual boost valve with the normal 3 point solenoid (thanks again Bealescooby), I've done the plugs (but need to remove them to gap them), I've fitted an STI intercooler as the original one looked a right mess and just fitted a Walbro fuel pump to it.
Now, it seems to be boosting happier but still stutters a lot around the 4-5k rpm rev range, then sometimes it'll pull like a freight train, others it wont. I'm starting to run out of options here now, the only things I can think of might be the gapping on the plugs (which wasn't done when they were fitted) or the HT's/Coilpacks might be old and worn as the plugs I removed looked they'd been in there since the dawn of time.
I'm just not sure what I need, I've seen some Magnacor leads for around the 40-50 quid mark which are affordable but original coilpacks are over 200 for all 4. My car is a 96 N Reg Classic Wagon with what I think is the EJ20G engine.
Can anybody help me out with the cheapest option possible as I haven't much money left to spend on this car?

Buy standard leads not magnecor, the quality is just not there. Thats assuming you have the single coil BTW as coil on plug doesnt have leads.
You have been warned.

you can convert it to use a 97/98 coilpack and leads as I have done on my car but it is not an easy job unless you are okay with soldering iron etc..

You do not need plug leads if you have individual coil packs which were standard between M/Y 93 and 96.
If you do not have coil packs but a single coil mounted on the inlet manifold, then you have a phase 3 car, M/Y 97. The O/E plug leads are good quality and going to anything else could be a retrograde step, assuming you actually have plug leads in the first place.
I have for sale a complete set of coil packs that have done, probably, 1500 mls maximum.
They are in the "For Sale" section for £100 delivered inclusive of Paypal.
I also have three plug leads in good working order.

Well thansk for the help guys, after inspecting my engine, the HT leads leading from the spark plugs go to some 2 pin electrical connectors which I assume go to a single coil pack but I may be wrong as I cannot actually see it, not that I know what I'm looking for. Does that help at all as to identifying what I need?

Bummer, that's what I feared. so what would I need to replace then, is it just the four coilpacks that connect to the spark plugs? Also what plugs would you recommend for my engine? its totally standard all except for an STI intercooler and a walbro fuel pump

This stutter you refer to may also be weak running for some reason and that could wreck your engine so drive your car in such a manner that this does not happen until you have the fault rectified and if new coil packs are not the answer get someone with a wide band Lambda to check your AFRs.

Yup - looking at the picture in "view my scoob" your car has individual coilpacks fitted.
Cars with a single coil pack unit have a box ontop of the inlet manifold with 4 HT leads going to it, you r car clearly doesn't have this.
(compare with my engine pic in view my scoob, if you want).
Also important note with re-gapping plugs. NGK PFR plugs should be correctly pre-gapped. (presuming you bought the right ones). 90% of the times these gaps are correct for a standard car. Re-gapping them can damage or break off the platinum tips on the electrodes, its quite easy to tell if you've lost the platinum by comparing the electrodes to a brand new spark plug. I'm not saying don't do it, just pay atention to what your doing and don't be ham fisted with the feeler gauge.
Also coilpacks can get damaged on removal/insertion: they contain ceramic, so avoid twisting or bending them. If the ceramic breaks internally, they leak spark energy.

Great, thanks for the help again guys. I might look into replacing the fuel pump and getting some more new spark plugs and correctly gapping them before they go in this time. Do you have a phone number or web address for tyne tees at all scooby_iain?

Sorry, what am I on about, I've only just fitted a brand new Walbro 255 fuel pump so that can't be the problem. (sorry, lack of sleep lately makes me even more stupid than normal). So really the only place left to look is the coilpacks then

I can send you out today a good set of coil packs that were on my WRX for less than 1500 miles before I converted to the STi 3/4 arrangement.
£100 inclusive of delivery and Paypal.
Where are you located? Other than replacing coil packs because these regularly go it would be better to identify the problem before you start trying other things so if the coil packs don't cure the issue I suggest you seek help from someone you can rely on and that may well not be a dealer who will have your eyes out.

Same issue with my 20G, Now I'm looking for a replacement as well. Has anyone tried Okada Projects Coils for the MY02 WRX, and retro-fitting them to the ej20g? I wonder if that would provide a boost in performance as well..hmm

Thanks for the offer harvey but I think I'm going to have to wait. I bought this car under the illuson that I wasn't going to have to spend a great deal and so far it's done nothing but cost me and I can't really spend much more until I get back into work
