i've been going up the wall trying to think of wat mods to buy the G this month, i thought i thought of everything. apart from absolutely going mental with pistion and knife edge crank..
puttin all they toothed belts and gt inlets and this an that... and still only using that tiny little i/c ?
wat could i fit with regular ease? or wat would be the bomb for gains and best for car?
i've not seen a straight bolt on polo i'c yet?
-
I've heard that the standard one is good for 180bhp, but obviously the cooler the air the better, so depending on your level of tune it could be worth doing. You do have to think about how and where to fit it, probably have to make up some brackets, and source all the necessary hose bits. I'm sure someone heres who's done it can tell you more.
-
If you plan on modding your engine further, a front mount would be the best option to cope with the increase in power. PSD made a front mount kit, however with psd shutting and steve vanishing you really aint got much chance of getting one of them, unless one pops up for sale on a forum or ebay.
Other front mount options are a 2wd cossie one, or even one from a bmw 330d, altho all the pipework would need to be custom made.
-
my mate chris used a land rover freelander intercooler,mounted behind lower bumper using vw golf 20vt pipework from a local vw brakers,an samco hoses,il see if he has any pics of it,as he sold the car after.
-
get searching your local scrapyards with a tape measure. There's loads of small front mount ics in there that are suitable for fitting to a mk3 polo, vw sharan tdi, bmw, frontera tdi....etc....
Or there are loads of universal coolers on ebay. Of course, any of these will require you to make mountings and get necessary boost pipes to suit. THe other option is to take it to somewhere like jabbasport, forge motorsport, allisport etc...etc... and just pay them to do it all for you.
I've got a 2wd sierra cosworth one with modified end tanks on mine. But to be hoenst you're better off getting something that'll more of less fit right on in a scrappy.
-
thanks for the replies,
im gonna have a wee search on the net and forums...
i might try the psd to source.. however hard it is,, ill try my best..
if that fails then a cossy cooler could be the one.. depends all on availability ..
-
PSD don't exist any more....
-
yes i know, but someone , somewhere where ever in the world will have one.
which at some point they will eventually decide to sell... to me!
-
You could measure one up and have it made to suit you. Cores are availble and then it's getting a fabby to do your end tanks and mounts !
-
BTW I wouldn't worry about the size of the intercooler. Without doing some calculations to work out things. I think the std one is adequate for G lader use. Might be a different story if you go for an eaton heat pump or turbo though !
-
yeah for me the worst thing about the stock item is the position of it. Not exactly in a good place for air flow and the charger itself stifles the flow out of the back of it. Plus even if the standard one "does the job", getting more heat out of he air can still only be a good thing. Plus the standard one is 1980's technology, more modern cores should in theory flow better whilst still taking as much if not more, heat out.
-
I think the position for air flow is pretty good as standard. Not too near the exhaust and rad, plus the ducting is fine.
I'd be interested to know how and in what way intercooler cores have improved.
-
well I only said in theory! But I would have thought that in 20 years they'd have done some development into intercooler technology? If you know otherwise then fair enough.
-
I'm not sure what difference is in the type of core. Will have a look when i get one and what alternatives there are. I'd be tempted to make a replacement in the original position if new cores will flow better.
-
I bought myself a BMW(E46) 330d intercooler just recently, brand new for £50(including postage), according to my measurment and calculations it should fit in front of the rad, but within the bumper without to much modifying. Just waiting for my subframe to arrive to start the task of rearranging the front end a bit.
-
please please 'g-spot' keep me dated with this...
maby a few foto's and tell me how you get on...
i mightbe tempted to move the standard ic, but the pipework that does the pain in the butt

What intercooler is that you're using Robin?
-
I'm wanting to get a front mount sorted for mine. Anyone who has one fitted, is there any chance you could have a quick look with a tape measure and give me some rough sizes so I can go for a look in the scrap yards? Also the end tanks would be easiest with rear entry from the engine side rather than the 2 sides I'd imagine? Where have people mounted theirs to?
-
Jake, the Cosworth Sierra ones are pretty good if you're on a budget.
They have cast alluminium end tanks with rearward facing 63mm inlet/outlet pipes. I have a 4x4 Sierra Cosworth one and the core size is 450mm long x 115mm high x 115mm deep. The overall length is approx 600mm.
The normal 2wd Sierra Cosworth ones are virtually the same but with 100mm (IIRC?) high/deep core.
My 4x4 one is for sale if you're interested?
-
wat price is on that ... ?
-
I'd like £35 plus postage.
-
kk would this still fit the same like 2wd version
i dont get the lingo on the (iirc) part ?
is it only 100mm high and 100 deep?
-
iirc = if i remember correctly.
i should be having a AW tracksport one fitted to mine shortly. Will get some pics when its been done.

Yeah Terry, the 2wd ones are 100mm high and 100mm deep.
-
this is a 2wd cossie one with different end tanks made up so the pipes come off straight. The normal connections on the 2wd one come off at funny angles, kind of 45deg on one side and different on the other.

-
ok im just wonderin will the 4x4 one fit just the same?
even tho its only a 15mm of difference deep and tall but i assumed it was a tight fit to begin with,
i think ill go for that 4x4 mentioned above ^ hopefully purchase after the weekend
-
what sizes are the 2wd ones compared to the 4wd ones then?
-
apparantly not :S ?
100mm ... 10cm very small to begin with..
any smaller than that it would be non existing
-
Only just seen this...
We helped Robin put his intercooler together, we've just set-up a trade account with Viper Performance and have almost developed FMIC for the G40s, be it turbo or standard Lader.
Got about 3m of varous diameter straights and a few bends left, but will be re-stocking shortly and have these out in kit form, I've not worked out prices yet, so bare with me :)

I've always used Viper Performance in the past and find the hoses to be excellent quality and fit, if there's demand I could also put together a standard G40 silicone hose upgrade kit, to replace the tired OEM hoses.

-
ill be first on the name list for fmic for 4x4 one :)
get back to me when you have a price
-
this looks like an good option for an mk3,if anyone is intrested...
a friend built it a while ago.
a can ask about type,fitting and the money thing.
pls.allow a week he is off this week.

How do you all go about piping to the passenger side connection on the front mounts? I had a quick look earlier and the radiator is right behind where the front mount would sit....

Is that the one made by Ralf Oertel?
Never got mine to fit properly, gave up on it................

Yes, it is, but is works fine and fits properly in my friend's mk3. Maybe my friend can help. Give it a try? Name the problems, maybe we can solve them. I will see him next week. I can take more pictures if you want me to. Let me know...
