Hi all.
I've decided to go full EV with my Capri.
I found an entire 07 GS450H not far away from me, its missing the hybrid battery but everything else is there.
About to start harvesting parts.
Transmission, inverter, splined input shaft coupler, drive shaft, oil pump controller, wire harnesses.
Anything else?
Shopping list from there.....
2017-2023 Tesla Model 3 Power Conversion System PCS OnBoard Charger with an EVBMW Tesla Model 3 PCS Controller
2015 BMW I3 CHARGING MODULE CONTROL UNIT, used.
ZOMBIEVERTER assembled.
BMW 740e batteries, maybe.
BMS, not sure yet

My knowledge of electronics is basic enough but I've done some.
I did build the donor car loom with sequential spark and fueling.
Twincharged 40psi boost control and delivery with PWM valves etc, (poor engine)
Direct port meth injection piggy backing off injector duty cycle.
So not entirely green to wiring and PCBs, really love making things work though....!

I've watched a lot of Damien's vids and I think I'm sold.
Maybe its his accent that got me.. I've been away from Ireland for 10 years now so it reminds me of home lol...
I'm confident I'll be able to follow along and get the thing going on the bench, most things seem very doable.
Just getting a little overwhelmed with the actual battery and BMS stuff.

I think as I get the mechanical end of things where they need to be I will doing a lot more reading and vid watching.

Any advice?

Thanks

Looking forward to this I did love my Capri's my first real car mod was rover V8 into capri
Does the 450h fit into the transmission tunnel ok ? the 300h is smaller and was a tight squeeze into my Z3
Anyway I look forward to seeing how this progresses (lot's of pictures please)

I'm guessing the transmission will not fit, I have a built T5 in there that needed the tunnel modified to fit.
As I'm not limited to a shifter hole I should be able to keep moving it forward until I get the desired elevation and driveline angles.
As I have an 8.8 solid rear on leaf springs I'm considering using the lexus drive but then putting the sliding yoke assembly to the rear of the car on the "pigs head" flange to take up the axle movement, that should technically work fine, its just not sealed from dirt like it would be inside the transmission tail shaft.

Heres a pic, my first and last paint job...

Lovely looking car

to have the T5 box and 8.8" rear axle what motor did you have in it to need that ?

The L110 is a large transmission. it sits lower in my Rambler than the tiny 1964 auto box that was in there before, but not so low as to be a problem. You can either modify the tunnel or just shift the transmission further forward. I put in an 8.8 solid rear w/ a triangulated four link and have the sliding yoke coming off the tail of the transmission with an adapter that goes from Lexus/Toyota to a 1350.

I built a 2.3 from a merkur, this was the XR4Ti of north America. Because someone said I couldn't, I twincharged it.
Compound with turbo blowing into supercharger.
The aim was elevated inlet vs exhaust back pressure.
It seemed to be quite knock resistant.
I hit 40psi of boost with this, all gauges pegged. Bust the 3 bar MAP sensor... haha..
Pretty insane to drive. Bottom end is toast now, crankcase vents hard. I have tinnitus from years of drumming so going for the quiet EV life now!

That piece looks the biz!!
I might be getting that then so.

I built an atlas for my rear, also made caltracs and used a mustang ARB..

That's a really tidy setup I turbocharged one of my Capri's very budget setup as I had little cash so used a second hand Garrett T3 with draw through setup and low compression pistons from a Ford transit van as they were all I could afford it worked really well right up until one of the pistons came through the side of the block Happy days

Thanks. I'm near sure we've crossed paths on the capri laser or capripower forums? Your name definitely rings a bell!

Today I got the lexus towed to my garage.
20 mins had the inverter out.
The hybrid battery is missing. And there's a spare transmission oil pump in a little box in the trunk.....?
Had a look and there's one on the transmission too.

Does that pic appear sideways on everyone else screen too!!??

Any battery experts out there mind giving me some advice?

Here's the specs from the battery I stumbled on, perusing the internet aisles.
Could 5 of these wired in series work?
They have a nominal voltage of 76.8 x 5 = 384v.

Assume I'm 5yo... school me please.

Yes the 5 batteries in series would work fine

Wouldn't have been me I've not owned a capri since about 1990 not owned a ford since, I'd have another capri if I could afford one in good condition but prices are silly in the uk

Got The transmission out..
That was a little challenging in my tiny garage with the car 1' off the ground. Started off so methodical, ended with a Sawzall!

Some other pieces to get before it's scrapped.
Got The oil pump controller, inverter, all loom plugs and wiring.

Need the splined sleeve and I also seen a little water pump

Splined sleeve? For locking the input shaft? That's just a cut down clutch disc. Not sure on the water pump though, I suspect people just use whatever is available to them and cheap.

Grab the flywheel/flexplate and "clutch" saves finding a clutch plate from something else it also gives you the option of mounting the complete clutch assembly to your locking plate to provide some cushioning to the driveline.

I tried mounting the whole damper minus the flywheel obviously and it made things worse in the 300h (l210) had to take it out and weld it solid but the 450h transmission may react differently you can only try

Not a lot to report.
Got front plate cut, 3d printed some stuffs.
Zombie arrived!
Comparison pics of the 450h vs a T5.
Got oil pump bearings too.

Cough Rust Cough.

We're running out of Mini's down here because someone's buying them all up and shipping them back to England and making a killing.

Have you tested the fit of those HV covers? Bigpie printed some off for me recently but the piece clashes with the downward facing coolant port on the inverter.

There is an updated version on Grabcad now,
https://grabcad.com/library/gs450h-side-port-1

Some progress.
The big hammer was introduced to make as much room as possible. It's as far back as I can get it without sacrificing too much ground clearance. Drive line angles are pretty good but I might have to wedge the rear end to get an extra degree of OCD... mounting brackets need some gussets and triangulation but it's looking pretty sturdy.
I was toying with the idea of using the 2 piece lexus drive but the center carrier cannot be mounted high enough to let the drive run straight and avoid the rubber guibo being stressed by a few degrees.
So I think I'm going to get a guibo delete and get a slip splined flange mounted to it. Then I can utilize the one piece prop I had made for the ICE and the solid rear axle.
If anyone thinks this is a bad idea please say!
Once I'm happy with the physical mounting and placement it all comes out for bench testing.
My honda fit accelerator pedal arrived yesterday.
So I have everything I need to start basic testing.
Looking at some Merc batteries too, but not entirely sure how the BMS can be controlled.

Looking great!

Are you going to keep the shifter? Looks like the output flange/guibo is sitting very close the shifter hole. I'm wondering what to do about that myself. Not a lot of room to work with.

Hi! Yes its extremely close, definitely no room for any kind of shifter mechanism.
I was looking at PatrcioEV-ATXs rambler and he has used this shifter... This looks like it would sit up top of the tunnel and be cable operated? Just need to dress it up a little.
I quoted him so maybe he will reach out.
His car is unreal.... goals!!!!
Failing that, I was thinking about some sorta steam punk lever mechanism that would go down the side of the passenger side footwell and go out through the tunnel near the shifter position shaft, water jet cut a PRND slot plate and have it all exposed inside the car, i bet working out the throw and lever ratios might be time consuming though.... But, it might look rather cool!
I have just settled on some batteries, and a whole shopping list of parts from ThunderStruck Motors.
Definitely more confident on getting this to actually work now.
There are some things regarding interlocks that need to be implemented between the zombieverter and the thunderstruck BMS MCU about final control that I don't fully understand just yet.

Yes, this one is cable driven and I use it move the gear selector. Bonus, when I drop in L, it shifts the transmission into Low. I'm using the B position on the gear selector to power a relay that grounds SL1/2.
