20b engine
ok so i've heard the term 20b engine tossed around and with the engine in the 3 rotor topic claimed 600+ hp.
my quesiton: is the engine in that topic the 20B production engine or the racing engine
discussed on this site link
is the 20b on this site the one that will enable 600hp+? or is it a production line engine discussed on the previous site?link
is there even a difference in the two?

you can get 600hp on a bone-stock j-spec 20b...conservatively.
there are TONS of differences between the production and the racing engines. here a few of the more important ones:
production has side ports, race has peripheral ports.
p has exhaust restrictors to knock down the noise, race doesn't
p had twins stock, race was n/a
6500 rpm vs 8500+
lots of other little differences, including the induction and exhaust systems, etc etc...

It's cheaper to buy a whole cosmo from japan and import it to canada.. have someone chop it and sell the parts you don't need. You can grab a whole comso ( some with less than 30K KM ) for less than $8,000 US delivered to your ( or your friends ) door in canada. The leftover parts, like new twin turbos and a bunch of other stuff will get you a couple grand.

i'm thinking of going 20b (u're running interceptor right?) and wanted to know whether there are much hidden cost to the project.
do you get any lean spikes with partial throttle w/ interceptor? just curious.
was also wondering if u found the power deliverable on tracks.
i just have many questions w/o answers
but one day, i shall have some answers!! thanks.

just a few quesitons if you don't mind:
how's the mpg? could you take it to a technical track or a high speed flowing track & put the power down without sweating your *****? say at ~350-400whp.
i'm mostly curious about the corner balance of the car after the 20b install. if the 20b engine is around 30lbs heavier with the turbo, perhaps battery relocation to the trunk can offset the heavier front, just like what you've done.
i just don't wanna spend 20k++ for installation & have it understeer or powerslide all over the track.
thanks rgonza.
