As far as I know it's a stock motor with a tdO5h, basic "big bore", chip and about 13psi. Looks likely the thermostat seized while someone else was driving it and it's venting to the coolant now. just wanting to put car back to as stock appearance so you wouldn't know. Plan would be have both motors on stands and then just switch over. Ideally I'd use a stock bc5 motor but if I can't find a good one I will just hide a better sti block in there with the bc5 set up running it. Is this a fair plan?
More info would be great , really appreciate it.
Yea all bolts up. You can't swap the rocker covers but I think you can run v1-2 coils and they fit? Or with wiring mods it's easy to run later model coils or wasted spark setup.
I've done it if you need more info. What spec is your current setup? Exhaust, intercooler, boost control, ecu, fuel pump ?
The applied model code for GF8-015083 is GF8C58D (build date 21/09/95) which comes up with this https://legacypic.uk/identification/index.php?appliedModel=gf8c58d
So yea, seems to be legit. It has the correct seats and door cards, and the centre boss with with STI embossing is uncommon. I'd check the engine numbers to see if they match as who knows whats in it as it looks like its been modded a bit given it running the wrong expansion bottle and they've removed the A/C.
Otherwise, looks pretty good
I have a cooked ej20g in my 89 RS. I also have a v3 STI motor lying around. Can I strip the EJ20k back to a long block and switch all auxiliaries, sensors, turbo and loom over from the ej20g and throw the motor straight in as a replacement? I suspect the rocker covers need changing to accommodate the coil packs?
A link or some instructions would be fantastic online.
