Porting the standard head is a more expensive route from what I understand

but the best option apparently..

xsi head would be the cheapest option I guess
(or keep the standard 1.8 head with 6-bits and a remap... also lowest gain probably..)

@ karazu, the sagem is indeed worthless, i've got a bosch which should be remap-able according to local chiptuners

@asim: can't be arsed to do the rebuild, none local that are willing to do/help with the rebuild and I'm far from skilled enough myself.
Already spent too much on the car, not willing to do so anymore. And I need my car daily! (may reconsider when I can afford a second car again)
Currently has 6 manifold/exhaustsystem and it's going to stay with that, sold all my other parts already Smile
Only remaining plans are the bmc cda, an alloy crank pulley and a remap.

What bosch ecu are we talking abouth?

I was wondering if just trading the minfolds and remap would give me at last 20hp more... (that would be fine for me...)

I will have to find that ECU and buy from UK, in Brazil thats going to make me mad, and crazy and I will never find it.

So.. if anyone can help me!=D

- thread revival -

not really planning this anymore, but I was pondering about this today and I'm sure some of you can enlighten me

the xu10j4rs head should be plug and play on the xu7jp4, but the one has a 86mm bore while the latter has a 83mm bore, wouldn't this provide, erm, 'incompatibilities'?


(thinking of this because I came up with the idea of replacing a mates broken xu10j4rs header with a ported xu7jp4 one, since we're having a hard time finding a gti6 engine)

sorry for the noob-question, but I'm sure this is the only place I'll get an acceptable/usable reply

Just a thought ,if the 1.8 is a strong and reliable lightweight lump , how would it cope with a low boost s/c setup and what sort of power gains ? They are 112bhp as standard I think ?

yup, would need extensive port work but valve sizes are fine of course.

should work well, would benefit from different cams and port work, Ash ran a 1600 crank in an mi16 block using a later xu head and a supercharger.

though likely to be a long way removed component wise, the WRC engines in the Xsara and 206 were based on the XU7 with special 85mm liners and an 88mm crank.

does that mean the engine mountings etc were the same then (wrc engines), and would fit straight in ? on the port work , the guru rich-w , does not recomend any on low or high boost on the xu10 lumps , so is the head that poor on the xu7and would still need work for charging ?
what sort of power did ash achieve?

standard xu7 uses same engine mounts yes, WRC variants are likely to be quite different, good luck finding one of those LOL

XU7 inlet ports are quite a lot smaller than the XU10, not sure what power ash achieved as a 1600, but there's a few n-a rally builds in the high 100's quite easily.

roughly 17 kilos, what sandy posted about them is quite interesting, due to the piston+rod+stroke geometry the piston speeds at a given RPM are quite a bit lower than the 1.9 and 2.0 engines, iirc this engine would see the same piston speed at 8k that the others see at 7.2k.

The head of the XU7 is good, but has very small ports - that makes it great for careful head re-working as it gives you more room to alter the shape and transition of the ports.
