Bluetop is 86kW and was released in the AE82 Range...
Redtop is 100kW and was released in the AE92/AE93 range...

blue top cant be just 86kw?
fren of mine has a blue top on an AE70 (very rare car) and it flies. even beats silver top 20 valves more than half the time.
just talking frm experience. his car might be exceptional

Depends ... Australian bluetop's kick out 86kw although the JDM versions kick out 96kw, probably due to higher fuel ratings & factory ECU tuned to suit.
That's not bringing into account American AFM motors which had less power than MAP sensored ones.

Technically they are a hybrid of both blue and red tops. Blue tops have always been used to refer to big port 3 rib blocks and red tops small port 7 rib.
I guess you can't shoe horn these ones into any 'colour' category. For me personally, I just say mine's a big port 7 rib AE92 / MR2 4AG and get by with it ...

Both if I'm not mistaken - the big port 7 rib first appeared in the early gen AE92 but was later revised and replaced by the 100kw small port 7 rib version that ppl refer to as the Red Top.

88kw. they also have the same internals as a bigport 4agze (eg. 42mm big ends and 20mm wrist pins), only difference is the pistons.
though some of the overseas guys have the same engine, but it had the 40mm big ends and 18mm wrist pin like the earlier 3 rib 4age. it seems Toyota must of done a run of the 7 rib block with the early internals.

internals are same as gze apart from pistons. does that mean i could just turbo using the same block and just changing the pistons?

remove the sump and splash tray and measure one of the big ends to be 100% sure. if it's got 42mm big ends then yes all you need is the 4agze pistons.
my current 4agte is running this motor with the 9.4:1 casties that came with it. if i hadnt of stuffed one of the pistons from my 4agze engine i would of used them in this engine.

sorry to keep bringing this topic back.
anyway, 88kw must be referring to the AFM model. i have one without AFM. that means its map sensor unless toyota came up with some funky EMS with it??
any idea how much is the output on MAP version??

if you look on the link i posted in my first post of this thread, you will see when you scroll down the engine comparison chart thing. they list the 'red and black' as 120hp (which is 88kw isnt it?) and they say MAP sensored.
i do find a little strange as they do list the AW11 as a car that had that engine but i deffinatly have a AFM.
looking at that pic in the twincam thread you still only have a 'red and black' 4age with bigport head and t-vis. so it will be the 120hp engine i have been reffering to.

a true 'red top' is 100kw smallport, all the writing on the inlet cam is red. some people confuse a 'red and black top' 88kw bigport as a 'red top'.
stupid cam writing colours...
