Coolant lines on Peugeot 205
 

Hi,

Maybe one of you guys can help me. I'm turbocharging my 1.4 Peugeot 205. Now i'm not sure where to get my coolant lines from. I was thinking of putting the turbo inline with the interior heating radiator. But the coolant lines from the radiator have a bit bigger diameter then the turbo has.
So maybe it is an idea to put a t-connection into the coolant supply lines of the radiator. Do you think this will work?

Pieter,

Look on your intake manifold for a source of coolant, most cars have some small coolant lines that run to idle air control valves/throttle bodys/oil coolers etc. The coolant lines off those items are pretty small 5/16 or so. So basically just make one cut in your factory line, then get a peice of tube to connect to the new hose, and run one line to the turbo, and the other back to the other cut in the factory line. (basically just run the turbo INLINE)

Good luck
Jeff

the 1.4 205 (xs) is carb fed...

ive seen a conversion on the same engine in a citroen ax gt, you can use the carb,blower and intercooler off A r5 GTT, tee into the rad pipe and run a line for coolant, theres nothing in the inlet..

the CR is too high on the blacktop TU engine for much over 7psi.. you'd be better of with an XU9j MI16

I've used both 'heater core' lines and throttle body water lines for a tap. The TB was the easiest because the diameter matched what was going to the turbo.

@ Jeff
Thanks, i have found a coolant supply hose to the intake manifold with about the right diameter.

@ Boost pixie
The original CR of my 1.4 (TU3s K2A) was 9.3 :1 the XU9j4 has a 9.7:1 CR that is the version with the cat the one without cat has a 10.4 to 1 CR.

I'm already using a Renault 5 gtt carb and intercooler. I've put in a thick headgasket, so the CR is about 9.0:1, still not ideal but a bit better. Also i'm going to use 98 RON fuel, so i guess 8-9 psi is possible.

I'm still not really sure how to supply the fuel to the carb, i think the original pump (camshaft driven) is not up to the task. I still have to find out how the Renault 5 gtt gets it's fuel, i believe it has an electric fuelpump and pressure regulator.

I'm doing this conversion to check if i can make a good manifold and to get some experiance with a turbo before i start with my Peugeot 205 2.0 16v (XU10J4)

If you are interested this is the engine conversion story (XU9jaz --> XU10J4)

Wow, what a change, from what it was to what it became. Loved the pictures on the site, but cannot read it. Anyways cool Job. Cool car. Just hope we get cars like that in the states someday :-[. I love the rally Peugeot and Citroen. Kick Ass.

Hey nice car dude! Wish I had one of those...

Anybody else besides me watch those rally car races on the speed channel? Fricking A those guys are crazy!!! Going like 90 miles an hour on little logging roads that I proly couldn't ride my bicycle through without crashing. :P

Out of curiousity - why did you use the XU10 Mi16 engine? it's heavier, and puts out less power than the XU9 Mi16 (155bhp iron block as opposed to a 160bhp alloy block). Granted the XU10 has more torque, but you may as well have put a Citroen XM Turbo or 406 SRi Turbo XU10J2 engine in (8v sohc turbo with yet more torque!!).

That way you wouldn't have to chop the inlet, do much work on the exhaust manifold and have a torquier car with the benefit of a turbo as standard.

It's what my plans for a trackday 205 are - in my eyes it seems more logical to do that than run a nose-heavy XU10 Mi16 in a 205.

I do have to admit though, your 205 looks the bollocks!!!

:o Wow, thats one serious tear down/swap you did there! Very nice! I liked you pictures!

yes, that is right...

if you use the gt turbo carb you sould really also fit the anti perculator fan that blows cold air at the base of the carb when the engine is switched off when hot to stop fuel vaporisation.. (mine is shagged, which is why its hard to start when warm.. as cb-dave knows as i plaged my mobile phone in the engine bay and give it a bit "vrrrrrrrrrrm , tish" down the phone.. after cranking for aaaaages to get it to fire, although it fires first time when cold
