I'm interested to know if it's possible to build an alloy engine using parts from other xu engines to make roughly 160/170hp. I'm sure its not as easy as that but wondered if any of you had tried or built something similar. RS head and manifolds? or would it be better to start with a 2l EW from a 206 gti?

I remember driving my 205 gti 1.9 and thinking what a difference having a light engine made to a cars handling. It was so direct and felt like the sidewalls of the tyres were well within their comfort zone. I love the "6" to bits but if could change one thing about it I would swap the lump of pig iron in the front for some aluminium.

I wouldnt want any more power than a standard "6" but want less weight. :therisa406forsaleverynearmegoingcheapwithaonepointeightlitrealuminiumenginesmiley

yes, quite easily, there's a couple of XU7 builds on 205gtidrivers, 28craig was the most recent IIRC.

EW is a good choice too apparently, they do make more qorque than the XU for some reason, the longman 190 kit on the 138 engine made 170 bhp with stock cams, throttle bodies and a manifold.

Does the EW fit in a 306 and do they sit at the right angle for gearbox or are they tilted more upright?

they are more upright, but not a problem if you use the original box from whatever car the engine comes from.

So basically there is an existing block that fits a 6 head and would run the same spec and is aluminium?

Basically what I want is a gti6 engine and gear box without a heavy ass block, is it possible?
Why no need for the head? Surely it won't be the same spec.

I recall a dyno print from a modified xu7jp4 you gave me once Mei.
The one with gti cams/both manifolds/reworked head/remap etc...
That one was pushing out 160 to 165bhp.

*edit* found it:

gti6 head is a bit big really for the smaller capacity engines, XU10 would work, or the XU7 ported.

Sorry I should say that the T5 engine is all alloy and therefore nice and light. The gearbox isn't massively heavy either and is cable shift so not hard to convert.

Really tempted to have a go, just need the money.

Was an impressive figure when it was built, seems mad now that they are getting that figure from n/a tu's!
