Nah its alright :P
I'll see how this "big-bore" n/a sohc job goes like. although its not really big bore, im just saying that because the over size number 2 rings are only .5mm by haynes reference, im going the full 1mm and from calculations SHOULD gain about 40-46cc from it. bringing it to a bore x stroke of 84 x 85 we will see what I can manage in my own garage, though the block and head will obviously get sent off to a shop for cleaning, boring honing etc. ill just get a shop to do the head, its quicker than I will manage on my own, and will be decked either 20 or 40 thou (for perfect mating, and for a tiny bit more comp.) home special port and polish job, best I can do without a flowbench, I need a new cam anyway, so might as well go SLIGHTLY more agressive, not much though. plus I think actually having a GOOD amount of compression in each cylinder is going to help the performance alot. |

progress report: upholstery
The fabric I chose is actually applying really well to the plastic trim using only kwikgrip. looks really schmick! not bad for a 60 dollar job. |

can i ask why you are spending money on your engine?
i really cant see why you would put money into one that isnt going to be anywhere near as good as a dohc/turbo |

EDIT: oh and for reference... i bid on the ACL pistons for the DOHC BP as well when I bought the SOHC pistons, it ends in 2 hours so if I win it, hey... 29 bucks for a set of pistons for a DOHC block as well, so if i did pick up a dohc block, id have the same amount of parts for either engine at current.

Although that engine is best bang for buck, I can't deny my heart for a little N/A :P though thanks for the advice since I know your trying to get me to realise how much more fun a BPT is |

please don't get that underdog syndrome too bad mate, it will cost you heaps, i know from experience. that said, the 84x85 predicted bore/stroke gives you a nearly square ratio, which makes for excellent power output. perhaps do the same thing but slap a DOHC head on? maybe some quad throttle bodies later down the track....

just curious are those adjustable timing cam gears you see around for the BP engine suitable for the N/A BP DOHC in the astina?

Yeah, any adjustable cam gears for B6 or BP will fit a BG BP

I must buy a haynes one of these days. I assume the wiring diagram is in it? Great project BTW. I look forward to seeing your upholstery job.

yeah the haynes manual is GREAT for mechanical stuff, however for minor body stuff you really need the 323F manual (I downloaded it from somewhere) which is bloody awesome for doing things like removing the headlight covers to change bulbs, or to find random things in the car. |

just checking the RTA light vehicle modification info sheets. I know your not supposed to fit an engine from an older model than yours is, but will there be any issue with fitting another engine from my series BG that may be 2 months behind my build date?

Ah finally I got some days off, had a relax and organised all my parts today. tomorrow is the work day. up at 5:30am to get fist deep into some of this work that HAS to be done.
-I've just sanded all back around the windows as there was quite a bit of surface rust underneath the black paint. its also been rust converted. Tomorrow it will be zinc primed / etch primed and given a new coat of gloss black -the front bumper is getting hacked, the middle grill is being gutted out (consider the bodykits that allow a big FMIC to pop through, that style) with all of the subframe painted fresh gloss black. -new gloss black on the lower trim on the front bumped and side plastic bump strips. -Numberplate will be offset to the left (checked RTA rules, this is fine) -Finish off some more of the interior Product test review: K&H Paint stripper. Really thick sex-jelly style substance, lovely poison warning labels. using mostly for my motorbike project. Managed to strip 5 year old baked on engine paint and near 30 year old paint off to the bare metal in SECONDS. this stuff is amazing. |

sounds like you're getting into some proper work now mate. i've never been game enough to attempt any kind of body work. lol @ the hectic side number plate, but i realise its functional for you. and cheers for the headsup on that stripper, sounds like pure awesome in a tube.
