I'm not sure this is the right place to ask, but does anyone have a way for a simpleton to work out my expected top speed etc?
(ie a formula rather than code please?)

The rear diff on my Reliant Scimitar is 3.58.1 and I'm wondering if I'll need to change that to use the GS450H transmission.

Did some work on 3d printing modular battery spacers/ cases that snap together and then can be be bolted together and keeps cells fixed in place an make them, easily mounted. Once I have them fully tested and figured out I will share them for anyone else with ease cells. That would be great! I woul...

Ah! Makes total sense, thanks SciroccoEV!
Got any suggestions for washers, or plated/stainless ok for that too?

Bit of a stall in progress but trying to get back to my conversion project. Made a mess of opening up the buck/boost converter part of the inverter, to allow access to HV terminals, but it'll do... 20210503_144011.jpg 20210503_144038.jpg 20210503_144544.jpg 20210503_150410.jpg Then spoke to some of ...

How do i go about flashing the new user-friendly version of the software, just received my board yesterday so hasn't got the new software installed. Ah...That's the million dollar question.. ;) basically this is what I did....(and BTW if you haven't figured it out by now I'm NO exert at this) The s...

Right, next job: As per the Lexus transmission wiki, i can't find the connector for the inverter (coming from the ECU - part no. 90980-12630 i think) so I'll have to rewire the inverter with a pair of new matching connectors. Can anyone give me any tips on how to rewire the new connector? Presumably...

The Lexus transmission had a lot of oxidisation on it so I decided to clean it up with lots of Autosol and my Dremel before it's mounted in the car. (Broke the Dremel somehow and took it apart to see if I could fix it but I think it was a broken wire right inside the windings so I gave in and bought...

Great project this and will be a very unique car! That chassis looks mint - definitely a worthwhile investment. Thank you! I'm sure they'll be plenty of challenges along the way but the Scimitar seems like a prime candidate for conversion to me. It's got a huge heavy Ford Essex 3.0 litre lump that ...

Ah thanks guys, very educational! Reminds me, I have been toying with the idea of calling my project "How NOT to convert a classic car to electric!" Seems more and more apt the further I go. Anyway, today I found a good deal on a really well refurbished chassis for the Scimitar, so once lo...

Hi Slanceley, I’m jealous that you are working on a Scimitar, I would have loved to have done that but availability of donors in Aus is kinda limited so I have finished up with a Super Beetle to play with. Now to the point of my email which is rather basic. As you admit to being inexperienced are y...

Never mind! Electric_SLK explained it all to me! Seems obvious now: the oil pump motor is three phase, hence the three pins in the white connector! I need the oil pump controller (and he suggested that the controller needs to share the same ground as the 12V supply). Next stop, ebay and some lexus b...

I'm having trouble understanding the wiring for the GS450H transmission oil pump that's on the wiki.
Could anyone tell me how to test that my oil pump is still working.
I'm assuming it's 12v applied... but don't know where to hook up the + and - wires....
Can anyone help?

M8 35mm bolts arrived so I've fitted the refurbished oil pump. (Next job is to test the pump runs ok before I continue.)

Hi Dan, well done for taking the first steps, and good luck with your project. I'm just getting going with my conversion, using a GS450H transmission and inverter in my 1971 Reliant Scimitar: https://openinverter.org/forum/viewtopic.php?f=11&t=1212 . Not sure how much help I can offer but if you...

I measured the depth required and it's about 35mm.
xp677 and ggeter in another thread confirmed the bolts as M8 35mm long, with thread of 30mm, 1.25mm pitch. Ordered some, arriving next week!

Brilliant, thank you guys!

I just used these, M8x30mm I think. Just sense check the depth of the threaded hole in the gearbox case.

Brill, thanks!

Thanks, I will have a go. I suppose if anyone else think's it's irrelevant or incorrect, they'll amend it?

Added to https://openinverter.org/wiki/Lexus_GS450h_Inverter Hi mdrobnak. I'm a bit of a newbie to this forum, could i ask your advice? I'm refurbishing the oil pump for the Lexus GS450H transmission too and having to find details of replacement parts. Is there some way I can help make this informa...

Also, in case it's useful to anyone...

Have replaced all the o rings in the oil pump as they were corroded. For others who are refurbishing this oil pump (part no. 56010-HRA030) if you need new o-rings you'll need are: 1 x 55mm int. diameter, 2.5mm cross section (For the black outer case). 2 x 50mm int. diameter, 2.5mm cross section (For...

GS450h transmission oil pump bolts and gasket... Bolts (4) 90080-10197 $2.76 ea Gasket (1) 35142-30010 $14 Has anyone got any suggestions for where to source these oil pump bolts, ideally in the UK (found a US website asking for $50 to post them here!) Possibly there's an obvious solution I'm missi...

Anyone know where I could find out what bolts I need to reattach the oil pump to the GS450H transmission?

(I bought them separately and forgot to ask for the bolts. Top tip for anyone else using this Lexus GS450H transmission, buy all the parts together!)

Bought some screws to replace the ones I accidentally stripped trying to disassemble the oil pump. (new one on left, old one on the right) 20210115_151445.jpg Then whilst the oil pump was apart I cleaned up most of the rust (not sure why it was rusty, left in a junkyard in Romania for a few years pe...

Hello folks, I've been using the forum a little bit more recently but only just found this thread. My name is Stuart, I'm based in Bristol but considering a move down to Plymouth/Cornwall.
