sr20de(t)

if a s15 sr20det makes 250hp with a turbocharger?? so how much does the turbocharger make and how much hp does a sr20de make??

[LaYzIeNoY]

i'm not sure of the numbers

but i would think that the extra power comes from the engine as the S15 has variable valve timing on both intake and exhuast valves

the S14 is only on the intake valves

i'm not 100% sure on this information but i'm pretty confident in it

the sr engines use 7psi boost stock and 7psi is still 7psi even if its a bigger turbo

SR20DE makes 160bhp.... so i suppose the 0.7bar makes 90bhp to get 250bhp?? I'm driving a S15 currently...... nice car to own!! lack of torque at high rev above 6000rpm

It's e same engine as the S14, but turbo is diff... it's using a bearing turbo unlike S14.

S14 engine and the S15 are a bit different.

Err... not too sure on this, but don think they have much difference like the cams etc... mayb pulley design? S15 radiator is smaller than S14... which is something negative. Engine alone, not to my knowledge, except for the turbo.....

Variable Valve Timing? It aint the same, dude.

I would be happy to knw if it's true.... but the review at Autospeed states this "One reason for the instant driving positives is the engine. These days it has a relatively pedestrian on-paper spec- two-step variable valve timing on one cam, single turbo, two-litre DOHC, 147kW at 6400 rpm and 265 Nm at 4800 rpm. At 8.5:1, even the compression ratio isn't particularly high for a modern turbo engine, with boost also fairly restrained with a peak factory spec of 10.6 psi." which means only intake cam with 2 stage variable timing...

Australia version... not jdm, but e engine is e same except it's down tune to lower octane... thus only 200bhp.

Im about 99% sure your not driving a s15....you sound like another "DRIFTSILVIA"..lol

[Hit_N_Run-player]

$hit, nevermind...your in singapore...i have no idea what cars are legal there lol

[drift_drift]

Guess ur 1% makes true......

[drift_drift]

My was imported... JDM spec!! will upload e photos in my gallery soon....... cheers...

The S15 SR20DET is a definate upgrade over the S14 SR20DET.

If only you would have been here when these posers kept coming around here in the past couple weeks saying that they had s15's in there garages waiting to be legalized (guy named driftsilvia) then you would understand why i had assumed that...Get pics up asap though!
