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

Re:Coolant lines on Peugeot 205
 

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

@ boost pixie

Thanks for the info but i'm not going to use the anti perculator fan, because i don't think i will need it.
The R5 engine has the exhaust manifold below the intake manifold, so the exhaust manifold heats the intake, the TU-engine has the exhaust manifold on the opposite site of the engine, that's why i don't think i will need the fan.

@CB-dave

I chose the XU10 engine for various reasons; first of all i wanted an engine with low milage. Mine has 38000 miles on it, just try to find a XU9 with less than 100.000, really hard to get.
Second, the engine-block of a XU10 is much stronger than that of a XU9. (you will probably also know about the horrorstories of pistonrods coming out throught the cilinderwalls, and the oilshortage in high speed turns)
Thirth, the XU10 has oiljets for cooling the pistons (it's the same engine-block as the T16, which i actually wanted, but they are just to rare and expensive), i really like those jets because i think they are very effective.
Fourth, the XU9 engines are known for not making their power claims.

I did not want the XU10J2ATE because i think the XU10J4 is a better platform for serious power.

The only downside of my engine is it's weight, i believe it's 50 kg heavier than the XU9J4

If you have pictures of your 205; i would like to see them.

he doesnt have a 205 yet, he has a 405 sri and is soon getting a 405 mi16

Re:Coolant lines on Peugeot 205
 

Pieter - mmm, T16!

I know about the oil probs with the 9J4, believe me - my 9J2 suffers the same, a baffle in the sump would do wonders though.

The low mileage part I can see too, but I'd still be wary of having that much weight over the front end! Pity you're in the netherlands, I'd not mind hitting a few country roads in that motor though!

The XU9 engines don't make their power claims because (as of your own admission) they are all relatively high-mileage, recondition it back to factory condition and it should make it's requisite 160bhp at the flywheel.

On the XU10, how are the oiljets fed and mounted? I can't find anything regarding that in any of the books I've got - are they fed direct from the pump or out of the block oilways?

My plan as it stands is buying my Mi16, transferring all the audio kit I've got in the SRi to that, sourcing some 10J2ATE manifolds, a 10J2ATE crank and reconning (or purchasing) another 9J2 to go into the SRi (my lump is totalled pretty much). Putting the 10J2ATE crank into the 9J2 drops the CR, it also unfortunatly drops the CC - making a 1.9 into a 1.8 with the compulsory loss in torque but with enough boost it shouldn't be a problem.

Plus, because the block is alloy - it should be a fair bit lighter than the 10J2!

After that, it's a case of running something like a boost-operated 5th injector and keeping the standard SRi management (it has a hotwire MAF meter though, so this may be problematic) and see how far I get.

Plus, while the engine is in bits - I can get the majority of the work done to it that I need to do (VSOS, head gasket, check the bottom end... I know mine is screwed but a replacement lump is a different story) and there's plenty of opportunity to tap water and oil lines for a blower.

Hi,

Was just reading your post why are you using a R5 turbo carb. You will lose a lot of tunability. What I have done is use the Renault clio 16V ecu and wiring, it can be adapted I have done the same for a 205 with a MI16 engine. I have alos used the same ecu to turbcharge a Golf Gti. Let me know if you would like to do this I can give you the info plus drawings and chip to start you up. It is very simple once it has been done. Ik ben in Nederland Morgen. Dooi
