Conversion n/a to turbo

[Ryan S]

hey peeps, away to to a rev2 tubby transplant into a rev3 n/a( i've tried the search, we all know what it's like) and i'm just wondering about the wiring loom, how is the rear clip connected??

i done a conversion before but it was that long ago i can't remember, i seem to remember something about the clip plugging in somewhere near the passenger door???

any help will be appreciated, thanks,Ryan

Yeah theres a section of loom that goes from the passenger footwell to the engine fuse box and then into the ecu

BOOM!!!! right there!!!! that's the one

rev3 n/a the same as a rev2 tubby???

should pop right on eh?

[Dundee]

Yeah thats the magic bit, as long as you have that bit they all join up

I mean you will need that part of the loom from the rev2 tubby

[Dundee]

Yeah should pop right in, however, if you have a rev2 tubby loom without the active sound system and a uk rev3 with active sound system that is where you will need some jigery pokery

oooh, it does in fact have the active sound system

cheers for that matey

No worries

And you will have to fit the turbo fuel pump if you want the engine to last more than a week or two.

will do mate, cheers

just out of curiosity, is the tubby tank bigger???

when i put a tenner in my tubby it hardly moved the gauge, when i put a tenner in the n/a the gauge went to about a quarter

[toxo]

Same tank. 55l in both cases. Remember the gauge moves much slower at the top than at the bottom

yeah but we had both tanks empty with the light on, is the ggauge maybe different?? smaller increments on the tubby??

doesn;t really matter, i'm going totally off topic

[bobhatton]

You have to turn the engine off when filling up a turbo or you will never keep up with it.........lol

Aint that the truth!!

[Ryan S]

thanks for the help guys, i will post back here when i run into trouble

[Ryan S]

right, had a look at this rev2, the wiring loom goes all the way from the engine, right through to the frunk

it doesn't split anywhere, i could have sworn this had somewhere it could be disconnected befor the frunk????,

[toxo]

Yeah, it should join through a load of connectors in the passenger footwell (below the door hinge). IIRC there are maybe 2 thick white wires that are permanent live which maybe go through to the frunk fusebox?

[Ryan S]

Well that's what I was expecting, but it's just one thick loom right the way from the back into the frunk, I think the whole lot's going to have to be changed over, i'll get some pics up, we're not in any rush, I don't think we'll be back at the car until next week, i'll keep you posted, thanks again for the help:)

The section of loom that we're discussing joins in the passenger footwell (connectors ID1, ID2, ID3 and ID4) and runs all the way to the rear of the car via the engine bay fuse box and rear lights, terminating at the electric aerial on the drivers side.

Contrary to what most people will have you believe, unless you start off with a loom from the same revision, and the same market (ie jap loom in jap car) then you will have some changes to make in the footwell. Pay particular attention to the connections for the speedo and ECU-IG circuit if swapping between Jap and UK.

[toxo]

Yep, even more of a pain if either car was a rev1 as that way you're missing one of the speedo circuits. Fortunately Toyota make it quite easy to repin their connectors, every pin is easily removable (there's even a guide with pictures available on how to repin different styles of connector).

[Ryan S]

cheers lads, the engine is comeing out of a smashed rev2 tubby and going into a rev3 uk n/a

the loom is all taped up etc, with what looks like NO connectors until it get into the frunk, we may just have to swap the whole thing over as this is looking like the easiest option at the moment
