R888s look awesome on the steels! My dad nearly bought a petrol estate version many years ago early 90s from memory, can't be many left now.
Engine sounds healthy. I have always found the old mechanical injectors take a breaker bar to crack them off. So easy to work on though!

"interesting" info for the statisticians astra gte 16v axle weights are 664kg front, 357kg rear, 1022kg total. weight distribution 65/35 astra merit diesel estate are 570kg front, 385kg rear, 955kg total. weight distribution 59/41 estate also has beefier rear beam, bigger chassis rails and box section cross member under the floor, between the rear turrets (to make floor pan load bearing for commercial sector) obviously the body work is longer and taller with more rear overhang this sounds ridiculous but the estate could actually be the thinking mans track car  |

Hi I'm a long time lurker on this site. My mates and I had a large number of these Astras in several variants back in the late 80's when they were new. So I really love this thread. While we all wanted the GTEs in reality that never happened. We found that the Belmont versions always handled better than the hatches and indeed the Estates where almost as good. I was limited in what tweaks I could get away with as mine were company cars. However my 1st a 1.2 merit managed to get Blydenstein Suspension under the guise of a service - lovely trip back from Royston. While my 2nd a 1.6 GL gained 14" rims and 16v front and rear ARB's and vented front discs. The handling on both was exceptional. The best of all was a German spec Opel Belmont SRI with the 16v ARB's and a Koni/Bilstein kit - sorry can't remember which.

They were all great especially the Corsa! I will see if I can find some pics for you for inspiration |

I will just leave this here ah! do you know the purpose of the mental inlet manifold ? it seems to go air filter > hose > top of inlet manifold > hose > compressor housing > hose > intercooler > hose > bottom half of inlet manifold whats the purpose of the top bit? some kind of plenum science bit ? |

The exact design on the inlet system differes from model to model but essentially the top half of the inlet manifold serves the same function on all models. The top half of the inlet is used and part of the inlet pipe work as such like a cross over pipe normally to get from the air filter on one side of the engine bay to the turbo inlet on the other side. Perhaps for the coolest (as in temperature) route available. I think they decided to do it this was as there is a safety valve between the two skins of the inlet (the bottom of the inlet which is the pressure side vents to the top side of the inlet which is the air inlet side) It's very common (as I did in the pic above) to bin the standard inlet and go for the N/A inlet manifold as it's much less restrictive and has no 'safety valve' plus it makes routing the pipe work easier and neater. Hope that makes sense lol |

Hope that makes sense lol ah perfect! yeah it does thanks. maybe its an antisurge thing like they achieve with throttles on modern diesels, to prevent compressor stall. or over-pressure runaway diesel type situation? what was the source of inlet manifold on the corsa picture? bespoke? there arent non turbo isuzu diesels i don't think? and the n/a vauxhall versions are reverse flow cylinder heads |

It's a pressure relief valve - I can't remember what they break at but it's less than a bar iirc if you want to run higher boost it needs blanking or removing. There is lots of info on line regarding 1.7 and 1.5 Isuzu Td tuning - I had 120hp and over 200lb ft of torque with out too much bother. The inlet on the Corsa above is definitely from an N/A 1.7D Isuzu engine (was the original one in the van) I did the conversion and polished the manifold. They start life like this  As you can see the inlet is in two halfs the same as the Td ones but it's just like a normal inlet inside and is very in restricted. You can split the top and bottom half and turn it round so the inlet hole is on the other side. |

Also it's best to get an inlet without the egr port (like the one above) as its one less think to blank

Poverty spec painted steels and centre caps FTW. I have a set of something similar for the winter rubber on the wife's Octavia Vrs... |

Coming along nicely. I might have 2 x 1.7 Isuzu lumps going spare in the near future. Both high millage at 190k and 160k though
