Hmmm, interesting Mine has a flat top tank which is thinner than those. It's completely flat along the top. Perhaps it's one of the iterations that Koyo have made along the way Then again I do have the "race" spec version so perhaps they envisaged swirl pots in the scheme of things. I suspect the core area may be greater too |

Yours is the copper Koyo so maybe its different to the ally one. I, sure youv'e posted pics of it somewhere but I cant remember where 
Anyway sounds like the ally version is a superior design to the copper one even altho the heat rejection will be better on the copper version

Hmm, This appears to also be an issue with the Golpher radiator for the ST185. The upper rad hose is the highest point not the rad cap. It shodul not make too much difference to me once a swirl pot & header tank is installed assuming it is done correctly The last bit is the real challenge

I am so glad I started this thread. Due to personal circumstances I have had to put project Arsey on hold for a while, I just haven't had the time. Now I come back to it I have a record of what I have already done and why! It has helped me compile a long list of "To Dos" as well 
Anyway - I hope to be providing some updates as I make progress! |

I'm glad you started this tread too. It gives me a chance to take the mickey that you broke your car 2 YEARS ago and still haven't fixed it

So Here we are some 7 years on....... Due to children, hectic job, house refurb, house move,then starting a business poor Arsey had been sat for far too long with an occasional wash and moss removal. Work has been started putting some of the planned mods/works into action along with some repairs that were needed and natural deterioration. Pics & progress will be added in due course... |

I can now say I believe in miracles having seen the state of the car before work started and the engine now runs  to say my flabber was gasted would be an understatement

Wow, At this heady pace it will only be another decade before its moved further under its own steam than the DC Removal Co have pushed it

It would have continued to run had the injector resistor pack been plugged in. two_OH_five wrote: Wow, At this heady pace it will only be another decade before its moved further under its own steam than the DC Removal Co have pushed it So how are your GT4s Mr Pot? There has been 2 very good pieces of news this week.... 1....  and 2.... after regular soaking in duck oil for the last 8 years the spring platform height adjustment collars on my Tein HAs have nicely freed off sufficient to allow complete dissassembly. I will do a bit of a write up on this as I could do with some input on options. The basic plan is to refurb & replace the excessively hard 10/7KG/mm springs with softer longer travel eibachs and maybe also look at adjustable inserts from Koni or Bilstein. The Tein/BC/XYZ etc all seem to have a very limited life before a rebuild is required and damper technology is very basic so opting for a better quality insert seems more sensible than paying Tein for a short lived rebuild. Most seem to suggest 10K miles before the shock blows. Esentially just using the cases / platforms to build up some bespoke height adjustable coilovers. This may be done in 2 stages as the dampers still seem to be working with adjustment on rate and are vary from a bit stiffer than stock to very stiff indeed. They don't however return to full extension of their own accord/are incredibly slow to do so. My experience with dampers suggests that they are typically pressurised to return to full height although I don't actually know what difference/why they are meant to do this or if all do. Ideally I would like to get spring rate & length sorted before getting the inserts matched to the springs/vehicle. |

Interesting - never see anything else that suggests BC's need rebuilding every 10K miles - unless it is the 'track only' version with the inverted cartridge (which BC strongly advise against using on the street). Mine have just passed that (including more than 1500 hard track miles over the last 2 years) and still look and perform like new. Tein seem to be more vulnerable to the British weather and can look very tatty after a couple of years though. |

My experience with dampers suggests that they are typically pressurised to return to full height although I don't actually know what difference/why they are meant to do this or if all do. I'd always assumed that dampers were meant to return to full height of their own accord after being compressed. A recent article in Racecar Engineer implies that this isn't always the case so I need to investigate further. I'd always assumed that the damper was knackered if it didn't return to full height. Maybe it's related to bump and rebound damper characteristics?BTW I don't think you would go wrong fitting Bilstein inserts as they do have valving specs for the GT-Fours. Koni may have something but I've not heard of them used in GT-Fours. |

Tein seem to be more vulnerable to the British weather and can look very tatty after a couple of years though. Good to hear. I guess an internet search will only ever reveal people who have had issues or people who have gone from knackered standard suspension to new coilovers and wax lyrical about how good their new suspension is. The cost of inserts & springs (koni or bilstein & Eibach) is akin to purchasing new BCs (circa £600-£700) but with easier rebuildability and changes of settings with off the shelf springs &/or bilstein offer cheap rebuilds with bespoke valving (circa £60 rebuild per damper seems to be reported). Anything I have read suggests that Koni/Bilstein is a step up in ride quality and performance than the japanese market equipment. I do wonder if Tein has lowered the build quality to match the price point of the newer cheap alternatives, my old spec Tein HA seem to have survived moderately well despite being very old. I am very open to alternative suggestions.... The vehicle will essentially be a fast road vehicle with maybe an occasional track outing. I am old so crashy suspension need not apply. Having previously had TRD adjustables and springs on my ST205 and Koni inserts/Eibach springs on my old ST185 these were a good compromise and a little more compliant than the Tein Superstreet which is more compliant again than the Tein HA I currently have. I ideally would like something that is a halfway house between the TRD adjustables (non-coilover) and the Tein Superstreet for ride quality. Maybe swapping the Tein helper spring for an eibach progressive tender spring may assist in a little more compliance along with lowering of the main spring rate...... I've started a number of calc sheets for spring selection so will be posting up for peoples thoughts. This is the first time I have entered into any detailed suspension calculations so any comments are welcome. The aim is for a little drop (but not much to keep roll centre and bump steer under control) and use as much travel as possible. In most peoples sense it will be quite high! |
