sure there's bound to be a way of doing something silly to it lol. Do you know what the most you can out of the standard internals on the 1.8 is?
Oh dear sorry to hear that :'( rust is nasty business..lighter than Carbon Fibre though
Engine work sounds promising though mate. Who was building it for you? And I bet it wasn't as cheap as my lump lol! Bargain of the year!
I've heard that from people about the 1.8 before yeah...suppose to be better for handling too as its lighter?
Ill find you a pic of the liners.
Im not sure how much the standard internals will take. Its hardly a used engine. Most people think that the gti is the one to go for because its the most powerful when in fact, its already highly tuned out of the factory and the 1.8 is extremely restricted from the factory. Also, they must of chosen the 1.8 bottom end for the WRC engines for a reason!
My engine is free so beat that

Yeah when i went over to the gti, i was shocked at how heavy the front end was. My 1.8 was a XS like yours so had gti spec suspension and the 1,8 handled so much better it was un real! I rebuilt my engine with the help of my old man. He used to work for jag restoring their older engines so im quite lucky in that respect!
And this is why i had to rebuild it

yeah 16v 1.8. That was on 91k at rebuild. It was very odd because it went very quickly. Literally a matter of weeks and it was burning a litre of oil every 70 odd miles. Only thing i didnt go was fit the new piston rings and scrapers as i dont have the tools but ive got a good rebuild shop nearish to me who supplied all the parts for the engine rebuild and cleaned up the pistons and fitted the rings and scrapers for £200 all in.
It really benefitted from a rebuild. was very very lively once it had been rebuilt. I just couldnt justify the extra cost of a new ecu and repairing the rust.
Have to be fairly careful working with the pistons and liners when the head is off. The liner seats are very shallow so they do move a bit. Dont turn the engine over without holding the liners in place (hence the big sockets lol) and try not to knock them. Worst thing would be to knock one, not realise then rebuild it and its mixing oil and water!
It was actually grant (guy who came to get a harness bar from you the other week) who bought the engine from me. He lives just round the corner from me so your not far so if you ever want any help with your rebuild, shout and i can pop over at some point!

Cant comment on the 6 exhaust mani. I never got round to fitting mine. Biggest let down is the 1.8 ECU. The sagem ecu just loves to shit its self for fun and doesnt adapt well at all to modifications. As a design, the gti manifold is very very capable. you should never ever have to replace it for more flow unless of course you need a custom one for a turbo. The best thing you can do is get it on aftermarket management once the engine is built. The sagem will destroy that engine by overfuelling massively if you try and use it and would be a shame to loose that hard work.
Omex is probably the best ecu that people use on the 306s but it comes at a premium. About £600 new and then another £70 for the loom connector and then the cost of building the loom (can do that your self if your confident with a soldering iron) and mapping.

the 1.8 head is very restrictive. I ported my one during my rebuild and in places i took off about 8mm either side in the inlet ports and i didnt go too drastic with it!
Bang the GTi head on there and that should be a winning combo. The head already flows very well with them big oversize valves. Couple that with the short stroke bottom end and it should build a winner. Dont bother with the xsi head though. It doesnt flow as well unless you want to put time into making it flow but theres no point when you can just go and buy a gti head.
The valves in the gti head are huge. Dont think ive seen an engine where the valves are so tightly crammed into the bore. Thats why all the 6 forum lot moan about them being difficult to time. On the 1,8 head, there is loads of room for error. None on the gti head!

Its a common part to fail on 306's. Which linkage was it that broke?
You can pick up a full set of BakerBM solid linkages for £25 at FCS. Thats about £50 cheaper than standard from pug.

Quiet loving the V8 gangster life if I'm honest. Nothing much beats the sound of a v8. Plus it has all the creature comforts one can only dream of ;-)
