not bad for the simple set up it is. This is with a stock KA24DE motor with 105k on it. Pistons 1&3 have 140 compression, 2&4 have 150.

wow that is actually very nice numbers given the conditions. the 2.4 liters definitly help make more then a SR even at the same boost levels.

[Florida240sx]

You got boost always ready don't you?

there is almost NO turbo lag whatsoever. 2k rpm's it starts taking off.

thank ya. and yup I love the KA and it's torque...can't wait to start building the motor to see what it can do.

I did ~202rwhp / 209rwtq form my old setup, at ~4.5psi.

Since the #s were so similar, I wanted to plot the charts over each other to see the differences.

My setup was T3/T04E, 57 trim / non-intercooled / Hacked MAF / Stock ECU...so the big differences are the turbo.

I did this maily to illustrate how 7psi from a small compressor like a T25 is the same airflow as ~4.5psi from a T04E compressor...

See below:



You can see the T25 makes more TQ down low (quicker spool)...but even non-intercooled, the T04E looks better up top (starting at 5000rpm).

This isn't a great comparison, as my graph had lots of smoothing applied, yours looks to have none...but it's cool to check out none-the-less.

Quick question for you Mustangs_suck, I'm planning to run a similar set up, and was wondering what you did with the water lines of the T25 did you just eliminate it? if so did you plug it up or just left it open?

Neat little comparison, and yup T25 spools FAST..almost NO turbo lag...but ya it won't pump out too high of #'s...def. good enough for me though

and no - my dyno run was just a quick few runs to tune it right, they didn't bother smoothing it out or anything.

Looks like a T3/T04E could pump out some pretty good numbers!

to be honest with you - I'd have no idea..the turbo came with no lines on it - and it's oil/air cooled (oil lines used from the previous turbo that was blown). I had other's install it - so if they plugged up anything I wouldn't know about it....sorry.

can you tell me the types of plugs and wires you used i'm toast by this basic set-up. to many options but it looks like yours probably came out best so far.

[erollinc]

can we see pics of the setup please!? im about to run the exact setup... i would have thought 7 pounds would get into the 220s ... hows your AF?

[nissanfanatic]

Nah, there had to be some smoothing. One with zero smoothing has freaking loops and stuff. Looks crazy...

Did you compression test properly? Throttle open?

Nice numbers. Glad to hear you got it tuned right now. How does it feel?lol Good luck with the car.

This is exactly the point orion was making. PSI does not equal HP. Airflow=HP. A large turbo can flow the same amount of air at say 4.5psi as a small turbo can at 7psi. Think of turbos like hoses. And think of air as water. A firehose obviously moves more water at a set psi than a garden hose. If this weren't true, then nobody woudl ever need to upgrade turbos.

180 ft/lb @ 3200 rpm, - nice

NGK Copper plugs. NGK plug wires.

The guy told me stay away from the iridium's they run a degree hotter, and aren't as good.

[:: orion ::]

... i would have thought 7 pounds would get into the 220s ... ?

My setup (again, with a T04E compressor) did 224rwhp at ~6psi.

See the chart here.

So IMO...no way will a T25 get you much better numbers than his @ 7psi.

Here's the pics:http://nissaninfiniticlub.net/...1.jpgh ... t/...9.jpg

My AF that run was 14.5:1 - which is dangerously high.

It's been set down to 12.5:1, but it was running hot, so they stopped running it. He got the fan working so it runs at what it should be..so if I took it back, it might squeeze out a little more hp/tq, but i don't think too much of a difference.

oh then lol - yes I guess it got smoothed a tiny bit then

Yeah, they had the throttle open and cranked it 3 times. They didn't unplug anything though (I remember in shop class we unplugged something before doing the comp. tests) but if that changes the outcome - I wouldn't know.

And thank you It feels good...put it at about 2500rpm's in 2nd and floor it - the whole back end kicks out and the tires start squealing until about 4k rpm's - should be a fun little car for now.

True - might be able to get a bit more, but not much i don't think. Pretty much running the stock set up as a SR, and I put to the wheels about what the SR makes at the flywheel

[Structure240sx]

i think i know the guy who bought that from. i used to talk to him alot on AIM (mrtakagarage) something like that

defintily a nice street setup, shame you went through a few problems

you got it...that guy's a f'in prick.

every single "mod" he put on the car was broken. I've had to replace every single thing except the SAFC and the intercooler with it's piping. He ripped me off for sure. I'm assuming he bought all the parts for dirt cheap prices because they were in such crap condition...and then sold them off as all good.

When I started getting on his *** about it he finally just said "dude, this is a used car, people expect these things to be broken on used cars" rofl...what a joke.

[Structure240sx]

yea, i hear ya

shows that you should never buy a car without seeing it and drving it in person. like buying a pair of shoes with trying them on

so true. I learned my lesson...too bad it took so much money to do it, but whatever....he'll get his in the end...karma works in mysterious ways.

rofl, at times I'd love to hop a plane to Flordia and knock on his door - but meh, not worth my time.

[Structure240sx]

almost is worth your time after all this, i think he was telling me he was keeping the silvia front end coupe with an sr in it, hmmm

sorry bad thoughts, i;ve been trapped inside most of the day, wish i had a street bike right now

[somthin240]

Hmm, I live in Florida. I could "visit" him! (edit:i don't exist)

[nissanfanatic]

haha, if structure comes down here, all of us will pay him a visit for you.lol j/k

yeah I know...I'd love to release some stress on his face..but *sigh* wouldn't get me anywhere in paying my car off....it'd just land me in jail or some ****.

and lol he was telling me how that car was all ****ed beyond belief and the motor was blown - trying to get me to pity him, so it didn't look like I was the only one having the bad luck....what a loser.
