Xu10j4 Vs Xu10j4r/s

[Bam 0]

hi folks,

 

i asking myself:

wich differences are between xu10j4 (97,8kw) vs xu10j4r(s) (110kw//120kw)

 

EDIT:

have found some infos (at the search)

so...inletmanifold,cams and ecu are the pysical difference (?!)

ecu: remapping would be work....

 

...i'm looking for the missing hores...

 

has anybody tried to fitt the gti-6 manifold to that 97kw engine?

(wich power it would be produces without the +1mm lift s16 cam?)

 

cheers mik

The cylinder head is completely different on these two motors. That's where the extra power comes from.

There's misinformation for a start. You're mixing up three different versions:

 

XU10J4 - 116kW, as fitted to series 2 Mi16 and S16

XU10J4R - 98KW, as fitted to 306 and early 406 models

XU10J4RS - 125kW as fitted to GTi6

 

The heads on the later two are completely different to the first. The XU10J4 head is almost identical to a 1.9L Mi16. Cam timing is a major difference between the R and RS but there's others. eg exhaust, inlet, cyl. head etc.

@peter

u r right...

 

pug is clever...they get a lot of "tiny" differences (began at the head, end at the block)

to get +30bhp (healty)

 

...and i'm sorry...i have typed wrong (enginecodes)

 

i'm not sure yet...to stress myself with this conversion (for "only" +30bhp)

Does the GTi-6 head fit onto the S16 block?

here are some infos:

 

xu10rs 120kw (gti-6/s16) inletmanifold:

TB diameter: 63mm / 70mm

 

xu10j4r 97,8 kw (406 2.0 16v) inletmanifold:

TB diameter: 48mm / 54mm

 

xu10rs 120kw (gti-6/s16) exhaustmanifold:

 

xu10j4r 97,8kw (406 2.0 16v) exhaustmanifold:

 

the 306 xu10j4r inlet manifold looks much different to both.

valves

 

xu10j4rs

inlet: 34,10mm (!)

exhaust: 30,xxmm (!)

 

xu10j4r

inlet: 34.60mm

exhaust: 29,60mm

 

valvestems on both engine: 6mm

 

camtiming (info from search)

RFV: 196°@1mm / 7.90mm Lift

RFS: 215°@1mm / 10.00mm Lift

 

inlet/exhaust duct-cross section ???

 

s16 block has a pistionbottomcooling.

 

ECU

gti-6//s16: magnetti marelli

406 2.0 16v: bosch

 

any correctionsuggestion?

XU10J4 = S16

XU10J4RS = GTi6

 

These are not the same, they have different heads, exhaust manifolds and inlets.

 

Also the XU10J4R head has exactly the same valve sizes as the S16/Mi16 with 7mm valve stems, while GTi6 is the one with 6mm valve stems and smaller inlets, bigger exhausts.

XU10J4 = S16

XU10J4RS = GTi6

 

i'm lil' bit confused...

here in germany, is the "s16"...the same, that you are calling here "gti-6".

peugeot 306 s16 (120kw)->xu10j4rs.

 

>These are not the same, they have different heads, exhaust manifolds and inlets.

pics above...i'm not sure...someone has tried to fit "gti-6" (xu10j4rs) inletmanifold to fit on his mi16.have seen some pic's.

 

> while GTi6 is the one with 6mm valve stems and smaller inlets, bigger exhausts.

so you agree? (list above, with valvesizes)

stems: ok,thanks for correction

 

...but whats about willxs question?

to swap xu10j4rs 120kw head (incl manifolds,cam) to 98kw xu10j4r ?!

bore is the same (86x86)

[B1ack_Mi16 67]

Lets call the XU10J4 for 405 Mi16 2.0 instead and drop the S16 thingy

 

The XU10J4 has 155bhp and a black plastic inlet manifold and cast iron exhaust manifold.

 

A XU10J4RS head would fit fine on a XU10J4R, I think the J4R will have 10.4:1 apart to the J4RS which has 10.8:1 compression.

 

And also I'm not sure how big the valve-pockets are in the J4R compared to J4RS.

 

But should fit just fine.

hmmmm....

 

next question would be:

i'm pretty sure, that a xu9j4 inletmanifold would fit the head from gti-6.

does anybody tried? (cause of 2x38mm TB's or VAG tb with 83mm???)

[Hilgie 16 2 Cars]

yes that fits....I did it the other way around, GTi6 manifold on S16(Mi16)head:

 

 

[Bam 0]

thx hilgie for the pix

 

whats about the oilspraybars from the bottom end from gti-6?

i also sure, that pug didnt make diff blocks, i think it should be possible to plug and play that parts

but....oilpumppressure difference?

 

.oO(what would happen with xu9j4 inlet and vag tb on xu10j4r,cams like this one:

268° 114° 10,5mm 1,1mm 20°-68° )

 

wich power should be possible?!
