The kit was built by my friend Nic, using a holset turbo off a Cummings Turbo diesel, he built his own manifold, intercooler piping and 3 inch exhaust
he fabbed the intercooler using one off the same truck. 440cc injectors, honda accord fuel rail, walbo 255 pump, and D-Tec piggy back. Turbo xs manual boost control
the car made 220 @ 6psi on 91 pump....ran out of gas so no tuning there
threw in some 109 and crank up the boost
enjoy!

and it holds the torque curve for all of about 1000rpm, lol. cool kit, but i'd try to do a little better with the turbo sizing... that's just not a very usable power curve.

try to do better on turbo sizing?
it was free! My buddy built the turbo manifold,IC piping,exhaust, intercooler end tanks........and sourced other parts from other vehicles
he built the car for less than $1500 bucks including the DTEC piggyback and new wastegate from turbonetics
The car makes 250 ft lbs for from 4k up.....and 220hp from 4k up
not to be too much of an A-Hole here but when was the last time you built your on turbo set up?.....on the cheap.....AND it worked.......
OH yeah...the motor has 144k on stock internals.......and was tuned in 110 degree heat

sorry man... just my preference to have the power start being usable below 4k. like i said it's cool as hell how cheaply he put it together and i understand that overall the setup works well and makes good numbers. but a diesel turbo is meant for a much larger capacity engine pushing much more air than the KA will flow so the turbo show's it's size on the dyno chart. that is all i was pointing out.
and as for building my own turbo setup... i built my whole damn conquest from a shell on the cheap and it worked just fine with a street tune on it.

Damn, not very defensive are you? Looks to be a Dyno qween to me. Pretty unusable powerband except for drag if you launch it 6k. I have built 5 turbo setups in last 2years. Mine being the 2nd cheapest one of all them. The FOERST one made 230hp-193lbs to the wheels for $1k on 6lbs. It was fast enough to stump the 04 cobras. My current setup is still under 2k but has micro tech fuel managment, runs 8lbs of boost making 200lbs of torque from 2500rpm-5500rpm when boost starts to die off due to to small of exhaust system.
Dont you think you could have atleast clocked the turbo differently so it doesn't do a 90degree bend? Looks like some ill routed oil lines that can chafe on stuff. So when does to cheap have to mean lack of quility?
I don't think he's being too defensive... just stoked that the car is done, and with a rare li'l setup. If I read the post correctly, the car ran out of fuel, so they couldn't tune it at all... so there is still work to be done in that respect. It does sound like a turbo setup this custom needs a lot of tuning... but my knowledge of turbo setups is slim to none... so I'm not 100% sure.
Either way... I'm interested to see what the results are once everything is dialed in!
You cant dial out turbo lag with tuning. Peak power means nothing, its all about the useable power band. But you could fix that hard 90 coming from the turbo that would help a bit. Adam you forgot to mention that your setup still uses an old skool distributor, it doesnt get any more low buck. Also this is why the web forums are whack, people post shit wanting to be heard, or for people to look at there ride. The minute someone doesnt kiss thier ass they get really defensive, and cry because someone said somthing the "poster" doesnt like. Nobody has thick skin!
Andy- I tried to send you pics, but it said the message was too big
I will move some to photobucket and post
I got defensive, because my friend has poured alot of time and sweat into this project.... It wasn't built to drift or do anything other than see if it could work. i posted it because I am excited about it as well because I hlped in some areas.... as for the power curve, I know its not the best, but like i said we weren't even sure it it was going to work at all........
I posted pics of the car a while back on the local 240sx board and instead questions/comments about the set up etc it became an a stupid argument about weather or not it was an SE model or not << who gives shit
he made a low buck turbo kit
I am not trying to dis anyone on the board...some of you have met me and now I am a good guy.....
If Nic decides to keep the car instead of selling it to me, a different turbo will be put on... right now the car is almost an enginnering experiment to him
Nic asked me to post this for him

Forum Responses:
If I were concerned about max power, obviously I would do everything
differently, mandrel bends generate turbulence in a bend; when trying
to
maximize flow an oval shape is best ; )
I have never driven a turbo car that wasn't fun; but I love cars, not
forums.
Obviously it is not going to live at these power levels; the pistons in
these simply won't take it; if and when I get another engine or decide
to
build this one; I will be shooting for 400whp on stock internal; if it
pops...oh well!
I spent about $1200 all together, but that does not include my labor
(fab
work); I also dug around and got alot of the material for nothing or
next
to nothing; this whole project was mainly to prove a point that any
engine
can make power without spending a fortune on it and that if you are
resourceful enough you can get by without spending the coin for a ready
made kit. I am not knocking those that by kits, I simply enjoy the
fabrication work. One of my tuner friends that I hold in high regard
told
me that I would not make over 250whp, he was shocked. I dig the KA
motor, I
love torque, torque wins races; horsepower sells cars. Everyone dogs
the KA
so I figured I would work with the underdog.
Thanks to Tony Szirka of UMS Tuning in Tempe, AZ ; Jeremy for
sacrificing
his finger while I tacked things together; and for the positive
responses
from this forum. Good luck with all of your projects.
