Don't know exactely which models do or don't, but some have drain plugs for the fuel tank.

That's certainly interesting, I wonder why only some and not all.

Very small update:
I went back to have look at both the mechanical and electrical speed senders today. As I wanted to see if it was possible for the mechanical sender to be swapped over into the Gen 3 S54. As it turns out it can and meshes nicely. I wont know for sure if this will work until I have it back in the car, hooked up and driving but it seems at this point in time I may not need to mesh up the Gen 2 S54 to the Gen 3 to retain the mechanical speedo.  

A few shots (thanks to Jaemus) from the MR2 30th Anniversary run yesterday.




 
 

Hey Declan, what are you doing with the old gen3 na motor? Want to sell me the throttle body tps sensor cheap so I can see if mine is stuffed? :)

Iv been using the engine for some spare parts but I will be getting rid of it once the rebuilt engine is in. No worries Nick, its yours. Sent you a PM, you just need to make some space in your inbox. 

So this little present arrived in the mail today. 

So as you can imagine; I was quick to get it installed and go out and test it in hope for it to solve the boost issues I have been having. 



SUCCESS! (kind of) I am now consistently making 18psi +/-
Spool is still pretty slow. Im not getting full pressure till around about 5k rpm. So I think I will still adjust the wastegate preload to try and hold the gate tighter. With any luck that might help reduce spool time. 

Nonetheless its night and day difference in power! 

Unfortunately progress has been slow on the red beast due to having started a new job. Though I will hopefully have some photos of where Im at posted up in the coming weeks. 

As for the yellow one.......
Well another hurdle has presented itself. My PWR radiator has shat itself  
This is the second aluminium radiator that has shat itself now...though originally I thought the first one was due to it being a cheapy but now the expensive one has done it as well. Not sure if Im just unlucky or that there is something seriously wrong with my car.
 
Time will tell I guess.  

What has gone wrong with the PWR radiator? I fitted one to my previous sw20 it seemed like a quality unit.

Just had one of those silly thought bubbles.  With 18 psi boost, are you possibly over pressurising your aluminium radiator. Maybe a head gasket issue.

Thats very possible. However its uncanny how it has lasted exactly the same amount of time (10 months) as the first one and has failed in exactly the same place (where the core meets the end tanks) where originally I was running the stock 13psi when it failed. 

I dont think it has anything to do with the radiator at this point as everyone knows how good PWR products are. Im leaning towards electrolysis at the moment. It would make sense as it would break down the veins of the core being that its where the material is the thinest.
