Head from Peugeot 206 - Saxperience

Wargod · 7th August 2014, 06:30

Hi everybody!
I have a head of a cylinder block from Peugeot 206. I've heard that it can be fit to Saxo. As far as I know, Saxo has smaller valves. Is it true? Is there a reason to replace the head? And if so, how much time will it require?
I ask you not to tell me to go to the search because my knowledge of English isn't so good.

Hi.

The head from a 1.6 16v engine in the 206 will fit without much issue (a few small modifications).

On its own though there is not much to be gained. Sure the inlet valves are bigger, but the cams are not as aggressive, so you you need to swap the cams to either the original TU5J4 cams or (better) specific TU5JP4 performance cams.

Realistically, if you want a quicker car, spend the money on brakes and suspension.

Thank you for the reply! I've already have good suspension and brakes.
Could you clarify what exactly small modifications?
I have n-group cams installed on Saxo.
Can I set up the cams from Saxo to Peugeot 206? Will they fit?
What are the best cams on Saxo (price/result) in your opinion? What would you recommend?

Off topic: if there's somebody who has racing experience, could you tell me about using 50mm wheel-spacers?

1. http://www.saxperience.com/forum/sho...d.php?t=323539. You'll need to adapt this guide just for your cylinder head. You need to drill and tap the head for the correct manifold (you'll need to retain the standard saxo manifold).

2 & 3. I wouldn't advise it. It's possible it would be ok, but some people have had problems with the casting differences in the head from the manufacturer when using J4 cams in a JP4 head. Better to use proper JP4 cams.

4. This is a subjective question. For what application? Drag engine vs road car, rally stage only on throttle bodies or weekend toy with turbo.

5. What do you need spacers like this for? The pressure on the hubs and bearings will be huge :/

So in order to install the head and inlet manifold from Peugeot 206 I will need to modify the holes on the head to make it fit the Saxo's outlet manifold?

i've gone though the guide and maybe I didn't understand something, but why do I need to drill holes in order to fit JP4-head in JP4 inlet-manifold? They already fit each other.

Do I understand correctly that the author of the guide installed a J4-head and JP4 inlet/outlet manifolds?

The other way around. he installed a JP4 head (actually complete engine) and still needed to use the saxo inlet and exhaust manifolds. The same as you.

You need to drill the JP4 head because the inlet manifold stud pattern is different, so if you wish to retain the saxo inlet you need to drill the head. The exhaust manifold stud pattern is the same - no problem there.

Thank you very much!
Are gaskets from the 206 and Saxo interchangeable?
And what is mileage of the down-parts of the engine of Saxo?
I ask because on Saxo it's 130,000 km and on the 206 it's 50,000 km.

I'm planning to use the 50mm. wheel-spacers on sprints. The most of our races are conducted on cart-racing tracks with lots of sharp corners.

1. Yes.
2. I don't understand your question I'm afraid. Down parts?

Re your sprints. We have several members who drive in hillclimb events who might be able to help. With this wide track it's best to wait for someone else to reply because I have no experience, sorry.
