Spinning the cold side

I'm going to be making a full hard pipe kit, but I also want to shorten the run as much as possible! I'm considering spinning the cold side of the turbo 180 degrees so the outlet points down instead of up! That would reduce the pipe work by a fare amount! It's a gr3071r, my question is this...is it actually possible before I start unbolting everything?

I can't answer that question but I take it your doing that to reduce the lag?

I would like to see how much difference it makes.

Even with the short pipe run intercooler spec r one I had the lag was still ridiculous! If I was going to do it again I would fork out a bit more for a 3076 with small exhaust housing and 2 and a half inch intake like what I had on my pearl car coz that thing spooled almost like a standard turbo

I have been thinking about this recently too, my concern would be how close to the block the outlet may come, may be a non issue. You may have to point the outlet slightly forward.

I think whytie has recently changed to a 3071 and his set up seems to be this way, so maybe he can offer some advice, he does have a aftermarket manifold though so don't know if turbo sits in stock position.

Yes to reduce lag, a friend of mine who is pretty clued up on this sort of stuff seems to think it will make a fare bit of difference! The spool on this turbo is not too bad and now Iv just gone from a 2 1/2 inch full pipe to a 3inch side exit I'm sure that will make a huge difference! I'm seriously considering having a vipec Ecu fitted soon with anti lag...and see how long the turbo lasts

Anybody considered other cooling methods as opposed to intercooler to reduce lag? I seem to remember Rob had some sort of charge-cooler set up on his old car.

charge cooler set up makes a whole world of difference in terms of intake temps and as minimal lag possible with a big turbo set up

the rest of it then comes down to supporting mods and finally how the car is mapped to get the best gains

heres the setup from our old track car which will be similar on the rashiteen were doing but with a larger turbo

My turbo sits in the stock position and I rotated it 180. It's very tight and I had to shave a tiny bit of the turbo for it to clear the block.

The other issue you come in to is making a intercooler pipe run with the front cross member and engine mount.

Charge-cooler lends itself to the gtir perfectly, good effort on charge cooler setup will leave even the best air intercooler behind in terms of efficiency & intake plumbing layout.
Only downside is initial cost & bit more fitting complexity.

This was what it looked like when I had a smaller md214 fitted (2871r)

The front mount I chopped and moved a few inches to the right



Now I have totally ditched the front mount and cross member

Custom made charge cooler bob? seems to be the way to go that's a gloriously short run.

Also where does the 2nd (blue) line on that catch can go? My breather system is set up the same but just vents to atmosphere because catch cans don't seem to come in single inlet.

You've ditched the cross member? Any more pics of your set up?

Very impressive! Is there not a mount to the engine on the cross member? I can't remember without looking?

There's a rock stabiliser on it and it's a good jacking point too.

If you look at my first pic closely I moved the rock stabiliser mount to the right and made a bracket that bolts on to the gearbox housing.

I've ditched the whole lot now

the other one runs back to the custom induction intake pipe

I saw the coolers you had on yours for sale, they are super cheap compared to the likes of AVT barrel coolers (£90 compared to around £700++), I wanted to know if you ever measured inlet temperatures on track using yours? How did you find the quality? How big a radiator did you run?

I think it would be possible to get set up for around £500 including a bosch pump and proper alloy radiator.

im using a pace cooling rad and filler, the heat exchanger is a gda unit I believe and think pump was bosch but supplied by them also. I never bought any of it as removed from a car we had in a few years back.

best thing I ever did was switching to this setup and away from air to air type.

seeing as my car was/is used (lets say harshly) on circuit, together with other track modifications the engine still lives on.
its covered almost 3k hard track miles now and when I pulled her apart ''as refresh it every year'' it is all still in top notch condition
I put most of that down to having fitted the charge cooler which without doubt keeps intake temps right down, the rest of it is just getting a good map in the first instance

Don't know who GDA are but those units (or copies) can be found on ebay. They look exactly the same and appear to have a similar core size to the "450bhp" size recommended by AVT unfortunately theres no spec on flow for the universal one, and quality may be debatable as it does look like an IC with a water jacket.
