were my expectations to high?

[djp.]

hi i just got my sr20det blacktop installed on to my 1989 240sx

Im not sure if i have a boost leak? or i just expected a lot more

i really havent ran the motor to hard just because i have a new clutch and i still need to replace the water pump, hasnt overheated but was told to run it on low rpm's until i replace the pump

but my question is that i feel the car pull at 3000 rpm's then at 4000rpms the car really doesnt move much and sometimes at 5000 it kicks in a little harder, does it kick in any harder after 5000rpms?

this is my first turbo car and i do realize it is way different then na motor,
and i really havent mastered driving it

all i have is an upgraded
fuel pump,
performance clutch from rpsport,
a rebuilt t25 stock turbo
and smic

Hard to tell by computer.

What was your last car? What are you comparing it too?

Your best bet might be putting it on a Dyno and checking power levels.

On a stock T25 you should be hitting full boost at around 2500 rpm. Also, do you have a boost controller or are you running at stock boost? Stock boost will only net 205hp, but compared to a Ford Escort it will really blow your skirt up.

well i had a sohc ka with an intake, and it doesnt feel that much faster

im probably just a bad driver.. lol

[koukimonster139]

nah

probably need to freshen up your engine a bit.

make sure everything is working and set correctly.


dyno

I would say something is a little off with your motor. A buddy of mine went from a single cam to blacktop and it felt a lot faster. I would say take it somewhere to test the thing cause it will definitely be noticeable.

[unicoladron]

there definitely has to be something wrong.

are you using a boost controller or is your wastegate connected directly to a vacuum source?

get a boost gauge, autometer makes good gauges and they're cheap.

i just went through the swap and i could tell the power difference by revving the engine in my driveway.

[statik]

^^ lol at feeling power of the essaarrr by revving the motor. You're running at least running 7psi, which should feel decently faster than ka, id suggest checking your timing.

[cotbu]

This usually happens when, you don't do the swap yourself. jk no FR
you now have a tuner, you can modify it and see gains instantly but once you do this it will never, ever end

[djp.]

ill make sure to pick up a boost gauge this weekend
and check the timing

thank you for the advice

[Nismoknightska-t]

yea.. i bet your timing is off..

[Omarius Maximus]

Well...you basically have a stock SR. So figure 205 minus drivetrain losses=maybe 170 to the wheels. If your in Cali and running the piss gas, maybe even less. Thats like RSX type S territory, or maybe even worse since those things are geared so aggressively. So figure 15+ seconds in the quarter mile.

Nowadays, a Camry V6 can do the quarter in the low 14s....time hasn't been good to the SR.

Buy a boost gauge. If anything, its a good tool to use for diagnoses of vacuum leaks or hardware discrepancies where your not boosting what you should. Also check for boost leaks.

[djp.]

i checked the timing and everything is good, i ran it pretty hard today and i must say it was pretty quick, third gear is pretty strong

the turbo does die at high end, understandable it is a small turbo

overall im happy, i think i was just expecting to much

[Koopa Troopa]

It's just an SR... Now go buy some 280 cams and a t04R
