[S13 Power]

Got a question for all of you..

Whats the diffrence bewteen a US SR20 and a JDM SR. Are all SR's japan built of are some built here in the states?

I know the JDM SR doesnt have all the emision crap. what about HP rating and such.

[Onizuka]

the us only has 1 version of the SR20, japan has 15+ versions of the SR20

US:-FWD SR20DE ~140hp

Japan:-FWD SR20DE ~140hp-FWD SR20DET ~210hp-FWD SR20VE ~190hp-RWD SR20DE ~140hp-RWD SR20DET ~205hp-RWD SR20DET w/ VVT ~210-250hp-AWD SR20DET ~210hp-AWD SR20VET ~280hp-SR16VE ~?hp-SR18DE ~?hp

Thats a lot of engines. Was the SR20VET produced by nissan? or is it just a SR20VE+T? What car came equiped with that machine?

Anyone which SR20DE had the 10.1 compression or something like that? I know the US SE-R's had the 9.5:1.

I just purchased my engine from soko. Theyre sending an JDM SR low port but i forgot whats the compression ratio on it. I asked him about the compression test and he said their 128 or better??? I thought SR20's were rated at 178 or higher? he said it would go up a little higher when everything like the electricals and such were all hooked up.

SR20VET was produced by Nissan in 2000+ X Trails

U.S. actually had two SR's.

The 91-99 SR20DE was ~140 HPThe 00-02 SR20DE was ~145 HP

The 00-02 used roller rockers with reduced frictional loss to give it the extra 5 HP.

whats the difference between the usdm sr20det (found in g20t) and the jdm sr20det.. like is the ecu progaming different ? are the cams different ? is the block different ? just wondering..

and j-spec.. did you froget about the 270sx, special edition of the s14 zenki that had 270hp ?

[Onizuka]

The G20t does not have a SR20DET, its just a trim level, still has the SR20DE.

no such thing as a 270sx, unless your talking about the japan-only 270R by nismo. Special editions dont count because there is no way in hell you will ever get one.

[irax]

good point... but i thought the G20t was the turbo trim... or i guess the ones that i saw just had a turbo upgrade then...

[Onizuka]

the "t" stands for touring package, which is infiniti talk for upgraded suspension. There is a Q45t as well. And a I30t. None of them are turbo from the factory.

No such thing as a FWD SR20DET, all the motors came with AWD trannies. GtiR produces 230bhp, Blue Bird(atessa) 205bhp. The newer SR20DET is referred to as an Avenir, has ball bearing T25 and doesn't come with a TMIC. GTiR is a hassle to tune and pain in the *** to get parts for. There is also a FWD SR20DE (Primera) 150bhp.

OT:how hard would it be to convert the sentra's to AWD since they came like that in japan ?

Too much work.....way too much.. just look under the sentra and imagine a drive shaft running to the rear end, the exhaust redone, what type of rear end you going to use, etc, etc..

Does the SR20DET come with forged internals?

How long do the turbos last on these engines?

No forged internals, just lower compression pistons, GTiR (8.3:1) Blue Bird (8.5:1). GTiR has 444cc injectors, T28 turbo and quad throttle bodies. Blue bird has 370cc injectors, T25. Both motors have piston oil squirters. The turbos are normally good for 50-75K miles or more. Just depends on the abuse put on the turbo.

^Con rods and crank are forged on DE DET is more of the same.

bluebird is a altima in the us and its fwd with the sr20det.. if not in japan, then at least i know in hong kong the bluebird has a sr20deT which is the altima

[Bennitto Mallito]

^ Dude all altima (bluebirds) with SR20DET are fitted with attessa AWD system. No FWD DET ever rolled off a Nissan assembly line.
