Evening everyone.

Im preparing my ED30 for stage 2 plus and i need to get a welly cooler fitted.

I havent ordered anything yet but have a list of all the parts need, one question though is regarding the bayonet fitting, what size do i need for the hardpipe down by the crank pulley?

Also does anyone know or have pics of how much of the front panel needs cut away to mount the 600x300x76mm core.
Also will having a black cooler effect its performance in anyway?

Many thanks.

You dont really need an welly cooler but it will be the best intercooler for this setup and if you ever decide to go big turbo too.
The bayonet coupler you need is 63-64mm. I got min from creation motorsport for about 23quid.

I didnt have to cut any of the bumper when fitting mine, but the crashbar does neet cutting to fit so you may want to think about that.

Black paint wont affect how the cooler works but i think the vents on the from bumper are quite big so stones may cause chips on the paint.

Of course you could go for a direct replacement like ths, wagner, perni etc

I think Mighty Car Mods did a myth busting thing on black intercoolers.  I can't remember the outcome though  :grin:

Is a welly cooler like a little fridge for Wellington boots or something?

I think some folk get a bit too wrapped up in "For stage 2+ - You must have a 3" catback, you must have a massive intercooler, you must have grade 7 spark plugs, you must have Millers Nanodrive.....".  You don't NEED any of it, technically speaking.  But a bigger IC certainly helps keep heatsoak down, but the more volume the turbo has to fill, the more chance of lag etc.

I think the Might Mods test made minimum to no difference. The only reason id stray it is if I wanted it to be a sleeper etc

Welly was the name of the first guy to try it universal intercooler on audi sport forums, about 5 years ago now. just a bit of banter that stuck.

Yes I totally agree. people going with all these name brand parts make the price of stage 2 ridiculous.

When I fitted my welly cooler I definitely noticed more torque, but I also noticed there was a bit of lag too. but once the intercooler had filled up its pulled hard and nicely. You dont really.

Even those cheap Ebay twintercoolers do the job for stage 2.

In other words dont break the bank lol
