Non Land Rover Intercoolers for 200Tdi engine'd 90's

[friday]

I'm currently looking into my options regarding aftermarket replacement IC's for my 200Tdi into 90 swap. The "off the shelf" standard size or, in particular, full width models by Brunel, Uptotheaxles, Allisport etc seem great but the price brings me out in a cold sweat I was wondering if people have used non Land Rover specific IC's in their swaps?

If any 200Tdi conversion owners, who have a full width IC already installed, are reading this it would also be good to know the measurements of the aftermarket unit along with the diameter of the Inlet/Outlets (though the latter is not so much of a worry as reducers can always be used....I think they're twin pass, right?).

So far, I've read about one person using an IC from a 1990 Toyota Supra, and the idea of using a Citroen Xantia IC was bandied about on another forum (though I don't think it was ever actually installed). There are always "universal" IC's available off Ebay which are a darn sight cheaper than buying an application specific model but the idea of getting an el cheapo scrapyard item that would do the job is very appealing...

So, if anyone has used an IC from another vehicle or has any thoughts on the subject, I'd be interested in hearing them.

Thanks,

Leigh.

Mine has a P38 Range Rover intercooler, which has been lengthened by about 50MM IIRC in order to clear a TD radiator.

Hi Leigh,

Have a search on the forum as there are loads of threads with regard to your question.

The one resounding point always made is that although it may cool your air better than the original you won't see a great deal of improvement in performance without additonal fueling.

Cheers

My Disco donor already had a bigger I/C of some unknown origin. It's as wide as it can be to be able to put into the radiator frame and some material is grinded off the frame to get the hoses in place. Connections are 50 mm and on top of each side so the radiator has been moved to the center. Height is approx 28 cm.

Sounds interesting Lars! Would you happen to have a photograph of it in situ? No worries if not though

gruntus: the reason I'm looking for a large IC is because I want to tweak the fuel pump, as the two pretty much go hand in hand

There are plenty of threads about full width IC's from Allisport etc and a few threads about using TD5 intercoolers but what I was really after was any info on using an IC from a different make altogether (preferably something easily available from a scrappy...and cheap!). The only thing I came up with was this: http://forums.lr4x4.com/index.php?showtopi...mp;#entry122727 which mentions both supra and saab (the 1st I've already heard about) but again no real info. Maybe I've missed something?

Although something like a P38 IC might be good I'm ideally searching for something that requires as little fettling as possible. Hey, it might not exist, but I thought it might be worth an ask just in case. To be fair, for the price they are, it's probably going to pay me to source an old Supra or Citroen Xantia intercooler for a few pounds and have a play

If worst comes to the worst and all the options look as if they'll be too much of a ball ache to get them to fit, I'm lucky in that I get a substantial discount off PACE so I'll give Mike a bell and see what they can do.

You don't need a larger intercooler to increase fueling. Fueling increases have no impact on the intercooler duty. You have to mess with the turbo for that to happen.

The larger intercooler just keep charge temperatures down when you have extended periods at full boost and higher engine speeds. The can help reduce EGTs if you run in this way.

Hi Friday, do you have any links to the threads ref using a td5 intercooler. all is have found or heard in response to using one so far is that it has the same cooling capacity as a tdi on.... therefore not worth it.

I would have thought they were a fair bit bigger.

B*gger, didn't save them, sorry chap No doubt I'll be doing a silimar search again soon in my hunt for more info so if anything crops up I'll post them

You want one of my Td5 intercoolers.....

Not that it really helps

Td5 standard intercooler has a larger surface area, so should in theory cool the air better than the standard 300Tdi.... but (as with any horizontally mounted single pass intercoolers) you do start inducing lag due to the longer intake pipe work needed to connect up to the turbo and the inlet manifold. Also you need to consider internal area etc etc.

I've heard that the Saab ones are good (as per dollythelw) and also some Volvo jobbies.... I've also seen one off a Iveco truck fitted to a Defender... I also looked at one off a new Renault that looked like it would fit

For a bit more bling, you could always start looking at charge cooler setups instead.

Or you could do what a friend of mine did. Go to a radiator shop that also sell standard intercoolers.

This place had a huge catalogue covering cars all through to HGV´s.

Measure the size you could fit, note fitting points, in-, outlet and browse through the

catalogue untill you find something suitable.

He had a Nissan Patrol 3.0 S6 diseasel and fitted a intercooler from and Iveco something, tweaked the pump,

made up a 3" exhaust without silencers, and the ting flew.

Last I saw him he had it on 38" tyres and would run rings round any standard LR diseasel.

We couldn´t keep up with him when we went to Iceland. I had a tweaked 300Tdi

Nicest sounding diseasel engine I have ever heard.

Thanks for the input guys, all very much appreciated, definately a lot of food for thought The Saab option looks very interesting indeed.

Porny: Ian, if it weren't for the fact that your second sentence made me think twice (and rightly so, thanks for being honest about it! ) I'd be asking for a price and no doubt swooning with shock right now...

Haven't had chance to read the articles fully yet but after quickly skimming them they seem a good and worthwhile read. I always used to hear about associated pressure loss and the trade off in getting lowered charge temps but an engine that runs hotter due to placement in front of the rad (without appropriate ducting to channel the air) associated with large front mounts but was suprised to find after searching threads on various forums that the possible downsides of front mounts is not a subject that tends to come up much with owners.

We're not exactly running high powered motors though so I wonder how detrimental (lag-wise) they would actually be in real terms for our application? The only way to say for sure would be to do dyno runs with differing IC's I imagine.

Ever considered the possibilities of a twin "side mount" IC set-up (if the faces weren't obscured by bodywork)? There'd be less obstruction (hopefully) to the rad, increased volumetric capacity (over the two units) etc. I have two of the IC's on the right in the photo below knocking about in the garage at the moment as it happens.
