Re: Turbo SVX

Those are WRX/STi coil packs. Mounted to a custom bracket with spark plug wires to the plugs. It's easy to wire them into the car, just have to find somewhere to mount them and a spark plug wire set for them because they DO NOT fit on the head over the spark plugs where the OEM are. The mounting holes on the head are in different locations for the coil pack bolt (ask me how I know).

The engine is currently stock. I'm hoping to take it to the drags and get a time before I swap the good 272 cam'd engine in.

That's correct. However I think they can be fitted to the head - guys with the RS Liberty (same era as SVX) often drill a hole in the other side of those coils and make them work somehow. Something I found with the stock coils is they won't go above 2-3 psi and when we tested the spark gap they'd jump it was only about 3-4 mm. The GDB STI coils jumped 25 mm and then we gave up testing... they work


A few issues I've stumbled across. The stock ecu runs the air con and I like the air con so I'm hesitant to remove it. I was going to create an adapter loom so I could connect my LinkPlus G3 ecu (the Link is currently running my turbo EG33 in racecar) but this air con issue stops me.

I am thinking that I may just have to splice into the loom and control simply fuel and ignition as the stock ecu does a good job with idle and air con and thermo fans at present - although ideas are good - anyone got any? For interest sake, my car is idling rather well thus far... no niggles as of yet.

Also one other thing, I cooked my speedo sensor as I got the wiring wrong. Here is the correct wiring. This is 02 STI but same for 02-06 STI 3 pin plugs.

Re: Turbo SVX

Would you recommend that standalone for a tuning newb?

Yes, I have the LinkPlus G3 - the new G4 is available. Very easy to use and I can setup a base map for anyone to get going.

I'll also document what needs to be done to get it into the car nice and easily in this thread. The goal is minimal wire cutting / splicing, ease of installation and we must ensure all the original functions still work.

I would seriously love you for all eternity. I've been re-considering goign with LANs chip, for the 555 sti side feed injectors. But want to be able to tweak things, or even the AEM FIC8, but Im unsure it will work due to our multiple crank sensors.

Please make a how-to, or short explination so that others can follow in your footsteps to a 350+whp EG33 powered monster.

My stock coils are good at 11psi!?!

Prolly more back pressure due to driving the turbine - not sure. We weren't interested in making something unknown work after they failed so early on - dyno time isn't cheap so we stuck with what we knew would run a lot of power with no issues. Made 580 bhp that day - dead stock engine lol, so it worked.

Could be.
I'm running a way too big true dual (at 2.5" each) untill a single 3" after the rear end.

Re: Turbo SVX

What the hell. How do electrical ignition parts have a pressure value...am I missing something here lol

The higher the combustion pressure the harder it is for the arc to jump the gap.

I've never heard of air pressure affecting electrical ark before... Interesting.

Re: Turbo SVX

I can't tell from this pic obviously due to the angle, but what did you use for spark plug wires from the STi coil packs to the plugs? I don't know of any wires off hand that would connect to the coil pack, and seeing as I have 8 of these coil packs floating around and 6 brand new connectors, I am interested in the last few details needed to make this work.

The higher the compression, and the leaner the mixture, the higher the resistance, for the spark to overcome.
It is the lean mixtures that we have today with Emissions, that demand the wide plug gap, and the much higher voltages that we have to use now. If we use normal mixtures, we can use normal small gaps, and normal voltages.

Could also be due to running E85, adds 30% more fuel and burns faster than octane and is harder to light (burn rate as proven by about 50 SAE studies, EPA etc) - you do certainly find more misses with E85 than normal fuel.

We also find that the richer you go the more likely you are to have a miss due to spark and we run mine rather rich as it's stock pistons. The leaner you go the engine just stumbles as there isn't enough fuel to turn it over etc.

With the coils - I simply removed the original rubber boot, inserted the original spring (which falls out when you removed the rubber boot), add any $5 lead from auto shop and cable tie the lead on with spring connecting the lead to the screw in top of coil. I haven't really liked this method and always wanted to improve it but it never let me down so I've never got around to making it better.
