Now then, just wondered if anyone has the BMW E30 radiator setup in their golf. Looks quite nice when its all plumbed in. I'm thinking of doing this with mine. I'm just looking for some pointers as to, can you use the original hoses, can it be adapted to take the coolant sensor, and how much clearance do you have at either side, between radiator and headlights (enough to mount a FMIC?)
Ooooorrrrrrrr, alternatively, is anyone running a smaller radiator to allow for a larger FMIC, and what setup do you have?
Cheers as always!!!

What engine you running, out of interest.
Also interested in this.

AGG bottom end PB head. Plan is to turbo it! Nearly got everything I need but I'm ideally needing a bit more clearance up front for the intercooler inlet and outlet, hence a smaller radiator!

On my 20vt I had a standard ras qith thw fan coqling. Used a saab intercooler and cleared inlet and outlet.
Even had the rad slightly tuched under the slam panel.

...by fitting a G60 engine and management with a turbo instead of a supercharger right?
-
No no no! G60 management, G60 throttle body, modified loom for ce1, stock 2e and PB head, RHB5 turbo running @ 8-10psi and a custom head gasket instead of stacking. Oh and an intercooler up front!
-
Mmmmm, sounds like a recipe for disaster :wink:
-
Depends how much the compression is dropped. And im not clued up in 2e interbals and how much they take powerwise.

Sorry, slight brain freeze there!! Stock AGG bottom end! Compression ratio is 9:6:1 I do believe. Looking to drop it to around 9:5. Having done a bit of reading from yesturday, 8psi. 10psi and I risk picking up the internals from the side of the road unless I drop the compression more, but then I'd be getting some lag. 8psi @ 9:5 ratio seems to be a happy medium.

standard agg cr is 10-1. but if you have had the pb head skimmed at any point it will be slightly over that. 2 mls headgaskets stacked should work fine for a decent compression drop. also I would be trying to get the intercooler mounted in front of the radiator as you want it to be the first thing the air hits. iirc the 2e bottom end had slightly stronger con-rods than the agg. not 100% certain on that 1 though. I would at least invest in some arp rod bolts just to be sure :wink:

Shamelessly stolen from another forum;
2E ADY 10.1 AGG 9.6:1 All rod lengths the same at 159mm.
2Es have the same head casting as an Audi 80's 3A 037103351H. This was touched in an earlier thread where a 2E inlet was used on my complete 3A motor installing in a MK2.
AGG and ADYs have the same head casting 0481033351D The only difference is the camshafts used so still does not explain the compression difference.
2E, ADY can use 0481033383B head gasket (fibre)
ADY,AGG use 048103383D (metal) stll does not explain compression drop.
The only non universal set explaination would come from the pistons.
2E and ADY carry the same pistons 048107065R
But the newer AGG carried 048107065S
If I was to go by common sense and the above infomation I would say that your CR difference is down the piston dish/deck height differences. A burette or dial indicator and some patience can always confirm.
Going of subject a bit here I know, but after doing a bit more searching, the spec for this turbo setup I've got was originally for the 1.8 GTi which has the 10:1 ratio, and was dropped to 8:5:1. How do I calculate how much 'thickness" of a gasket or spacer I would need in relation to the 9:6:1 ratio of the 2.0, to get it to the equilavent of how much of a compression reduction there was for the 1.8GTi.
(I think that makes sense?¿?)

if the gasket diameter is 83.5mm you would do .7854 x 8.35 x 8.35 = 54.7600515 which would be the surface area of the cylinder ring in the gasket in cm2. so if you change that to cm3. as in from a flat surface area to 3D. you would divide 54.7600515 by 10 which would give you the volume ccs of a 1mm thick gasket which would be 5.47600515 cc. hopefully i explained that right :wink:
-
Yeah that makes sense! Sooooo, if the ratio percentage of a 10:1 is 9.09 and it drops to 8:5:1 giving a percentage of 7.14 then the percentage drop would be 1.95. So if the cubic capacity of said cylinder is pi x radius squared x height bla bla bla would give a 661.33cc per cylinder which would need reducing by said 1.95 ratio percentage which would be equal to a 12.896cc increase which goin back to your calculations would equate to roughly a 2.5mm gasket. If that makes sense!! Hhhmmmmmmm????

Pretty sure some maths need checking there...
However I'm only doing it in my head, needs some pen and paper work
Never seen so much maths on a car forum. Be discussing aerodynamic drag coefficients next :grin:

Makes a change to the no point doing it.
Started of as what rad people use :grin:
