RE: new engine
Pat,
Please see responses below. Thanks for the advice and I would like to hear
your recommendations regarding exhaust and intercooler (see below).
Thanks again,

Congratulations. The process has started. Did you follow my 1st
instruction in my conversion post. Is your current motor wet:-).
>>>>>>Not wet, but extremely weak and fuel-inefficient, even by 4k
standards. Plus, had to concede to the wife to sell my motorcycle to pay for
this project (not easy in the winter).
Did you get: both wiring harnesses, computer, after run equipment, hoses and
intake lines ect. ect. ect...
>>>>>>>>>Haven't got the engine yet, but yes, everything is supposed to be
included, even the oil cooler and intercooler, which I may or may not use.
I feel that with

Those are reasonable expectations. Not sure what intake mods you can do to
do any good but definitely think hard about what you are doing for an
intercooler. 3" exhaust. No smaller.
>>>>>>>>Intake mod is the TAP cone air conversion designed for the 5kt.
Already have a Scorpion exhaust (not sure of the diameter), but am
considering other mods - downpipe, 2 piece exhaust manifold (too
expensive!), very free flowing cat (you know the kind I'm referring to!),
and possibly larger exhaust valves. How is your car or Pete's car set up for
exhaust?? Also, what is your recommendation for an intercooler? Is the 20v
intercooler really more efficient? Are some dual pass vs. single pass?

It does pull pretty well. I am running 12lbs of boost right now and am
probably in the 5-6 second range for 0-60. Very quick. Petes car (march
ec) has the k-24 and is running the same boost with stock intercooler and
stock exhaust. His car is more responsive a lower levels but up high looses
its oomph. Could be the exhaust but Ned feels that the turbo might be part
of it too. His 0-60 is very close to mine but slightly quicker. Another
friend of mine has the same motor as me but with a custom intercooler. His
car is slightly slower at lower rpm but gets better up high. Depends allot
on the weather.
>>>>>>>>Is Pete's engine the early lower compression MC motor, except with a
K-24 turbo substituted, or is it the later dual knock sensor higher
compression one with the K-24 stock? Also, again, tell me what you know
about intercooler options. Which intercooler are you using?

Resounding YES. The 20v air intake is much easier (PLAN NOW), and the tie
rod stays put. Other than those 2 things pretty much everything else is the
same.
>>>>>>>>Oh well, $4500 for a 20v motor was definitely not in the budget.

You will not. It is an expensive as well as long conversion. Expect 4-6
months of down time.

>p.s. Pat - how do you like the Yoko A520's and what size are you running?
Like them ok. Slightly less aggressive that the previous AVS intermediates
but they wear slightly better. Would highly recommend a set of track tires
though.
>>>>>I've reconsidered. I think I'll continue to use the 15" wheels year
round for the street (with something stickier than D60s in the summer) and
get some competition tires with 16" wheels for autocross/track use.
40-series 16" tires would not be too practical on the street, and I don't
want to bend any expensive rims. Believe it or not, even with a very STIFF
suspension (lowered about 1.5"), my FRONT tires (currently 205/50-15 on 7"
rims with et37 offset) rub on hard cornering. I'm hoping a front strut tower
brace, which will be installed once the battery is moved, will solve this
problem.
