There is no such thing as a FWD SR20DET. They are all equipped on AWD platforms. Fortunately for us they are an almost 100% direct swap (3 bolts don't get used).
For answers to your questions, go to the forced induction forum.

ok so now i ask, what gives the jdm primera fwd sr20de the extra 20hp that the us sr20de is lacking?
Also can some1 tell me what egr stands for... i'm lost.
Long story. All Primera JDM SR20 motor HP is rated 150 hp. But Nissan did make changes on Primera SR20DE motors several times in past.
I say 150 is the number Nissan claims, but earlier version SR20DE probablly had more than 150hp. Back in 1990, Nissan used the first generation SR20DE engine in P10 Primera. That engine came with tubular stainless steel equal length exhaust manifold. The cam profile was pretty agressive for factory motor. (248 in 10mm /240 ex 9.2mm). Only first generation SR20DE motor came with sodium filled valves seen on DET motor. In September 92, when second generation SR20DE came out, sodium filled valves were no longer on that motor. In 1994 when P10 got the final minor change, Nissan took off the nice stainless steel manifold and changed to cast iron exhaust manifold instead.
When new P11 Primera came out back in 1995, Nissan made the another changes on that motor. If you look at the intake manifold, that's the biggest difference. Yup, that's the famours "high port->low port" thing. They lowered the Redline from 7500 > 7000 also. The new engine came with roller rocker arms with newer/weaker cam profile (240 in / 232 ex). So those are all 150HP motors, but First generation SR20DE was obviously the fastest and had most power. They all came with 10.0:1 high compression pistons with ECU with agressive fuel map and require 100 octane premium gas.
I knew this for some reason and just wanted to share this info.
EGR - Exhaust Gas Recirculation.
Under certain conditions exhaust gets pumped into the intake. Why?? To lower combustion temps which leads to lower NOX emissions.
Have a nice day

That's 150 ps, not hp. Small difference, but a difference none the less.

Do you have documentation of this? If so, please cite it. I am completely unaware of any SR20DE that ever came with sodium filled valves. I believe this is a DET only item.

Actually, it's 7100 rpm.

Not initially.

That would be 100 RON. It's quite different from US pump gas octane number. Our pump octane numbers are (r+m)/2, or in other words, and average of research octane number and motor octane number. Gasoline with a 100 ROM is probably about the same as our US 93 octane.

I have to apologise about me posting a bounch of wrong info. I don't think i know crap about engines, so I shouldn't be even talking about it. I'll just shut up. Thanks for the correction.
not only is this a DET only item... it was ONLY the Pulsar GTi-R that got these. The bluebird has standard exh. valves. I cannot say forsure on the RWD DET's.

S15 Autech Silvia SR20DE (non turbo) has sodium filled valves. I got that info from Autech homepage. I was reading the Nissan Primera SR20DE tuning magazine from Japan and it said first two years, SR20DE came with sodium filled valves also. Since they are written in my native language, I am pretty sure I didn't misunderstand that.
I have a European Spec ALmera GTI which uses the SR20DE engine. As standard my Limiter is at 7500 im sure there are Euro ECU's out there somewhere. I can get 150 on a closed road it wont hit limiter but its close.
if I am not mistaken, the last few years of the G20, they have been using the sr20VE in thier car. Im not too positive on this, but Im sure that th HP rating is 180 right?
correct me if I am wrong. But if your searching for extra ponies, and also more ponies to start with before mods, why dont we use that engine. the dimensions are practically the same as the SR20. I think it would jujst BOLT IN!
that is what I would do.
by the way. If this is all as true as I think it is, My aging 91 SE-R could really use one.
If your gona do an engine swap why not get the SR20DET engine. It will cost more but its got 200 HP and thats standard. You could have 250 HP with a few other mods. Header, s3 cams, JWT ECU upgrade, CAI. Costs more but more power so i guess you get what you pay for. Im looking to do an angine swap my SR20 for the DET next summer. Ive calculated around 3500 bucks.
150hp is what Nissan claims.
agh..... I'm a dumb ass
