Allow me to introduce...

...the new RWD SR20DET Frequently Asked Questions.

I've spent some time on the material covered and I have a lot more I'm going to be adding once I have time to sit down, compile, and format.

Since I'm leaving the FAQ locked, put your comments, likes/dislikes, and requests in here. I'm sure there's a lot of number errors and the like in there, so catch em so I can fix em

Coming updates:-Basic swap procedures-high-port versus low-port (if I can find enough info to do such a thing)-picture additions for visual identification

Hey Bart. the link for additional info on clutches doesn't work, and I think you mean 15w- 30 not 50 that's all I saw at a glance.

[Hijacker]

I meant 15w50 It's what I use during the warm months. I've been running that weight for 4 years now on recommendations from back in the day. I'll add other recommendations to the list, though. I don't want that to be "Well I run it, so you should to" list

Fixed the link. It was meant to link to the parts sticky.

[homeslicej2]

Oh. I was told that 10w-40 was good to use in the summer, so I assumed you meant 30, what kinda of pressure you does your SR run on hot, humid days (90+, and 90%+) with 15w-50 and with what kind of oil?

[Hijacker]

I've never had an oil pressure gauge hooked up, to be honest.

And I usually use Mobil 1 synthetic

[IanS]

I also run 15w50 during the summer, for about 4 years now, there is only about a 2 psi difference between 10w30, 10W40, and 15w50.

//End thread jack//

I caught a grammatical error.

Under Differences Between FWD and RWD, you wrote that the dizzy is ran off the rear of the exhaust cam, it should be run.

I also have some additions to the Maintenance items.

For the redtop and early blacktop you use the filter for a B13 SE-R, but for the S14 and S15 notchtops a filter from the B14 200SX SER should be used.

I know this is just a rough drafts, and I have a few suggestions.

I think you should add some pictures with the differences between engines pointed out, because todays youth just cant seem to learn without pictures.

I also think you should add some information dealing with the 180SX type X engine, because it was essentially an early model black top, but it received a T28 and IIRC a few other goodies, also explaining the issues related to running a J4 ecu should be mentioned.

Also, a mention about the high port heads with/without fins, the early model redtops had no fins, yet the late model redtops and all of the S13 black tops have heat sink fins on the front of the head. I would also suggest labeling the S14 and S15 engines as Notchtops instead of blacktops, I think it helps differentiate the two, making things easier to understand. I also think the section detailing the differences between all the engines should be expanded, I think a lack of understanding of the engines themselves is one of the biggest causes of repeat questions.

Another thing that definitely needs to be in there, is an explanation of BOV recirculation and the benifits of it.

All in all, I think you've got a really good start, good luck.

Only the idiot light!!! no!!!

Good to know. thanks Sideways and I too think that a better differentiation between the S14/15 motors and the S13 blacktops would clear things up with noobs.

[Hijacker]

I have a couple of pictures already lined up for comparison shots, but I got busy building my motor last night and din't get around to photoshopping it. I suppose I could grab the pic Onizuka used in his "How to tell the motors apart" thread for a placeholder in the meantime...

What I would really love are some clean pics of the different generation motors. All the pics I have are from importers, so the motors are all dirty and covered in junkyard grime.

Only the idiot light!!! no!!!

I admit I've been lazy and retarded, but an oil pressure gauge is low on my priority list.

[IanS]

^^^ When the motor calls, there is nothing you can do.

I figured you were planning on putting pictures in, I just figured I would mention it, just in case.

[Hijacker]

I'm gonna scour the SR Picture thread later for some good, clean shots. However, tonight is head installation and block painting. The block's been hot tanked, scrubbed, and zapped with simlpe green, and it's still dirty as hell on the outside. So now it gets a good coating of engine paint aluminum.

[homeslicej2]

Understandable.

I can get you some pics of my early Redtop (no fins on head) if you'd like. I don't know if it's clean enough (the wiring certainly isn't ), but it might be better than what you have now. Do you have a build thread yet?

[Hijacker]

I've got some scattered parts threads. I'm waiting to put it all up at once for the How To I have planned

great! Looking forward to it.

[Kalypso]

well done! lol!

I've seen new posters get your hostile. <<< MASSIVE SEARCH BUTTON!! >>>posting.

the time is perfect.

[Hijacker]

I wouldn't really call it hostile. I would say it's more sarcastic and hopefully slightly embarassing.

[redtop91]

The info in the fuel pump and injector life is definitely new. I always assumed it was bad injectors that caused mine to tick sooooooo loudly but now that I think about it, that wasn't it at all. Learn something new everyday.

[Hijacker]

That's just an observation I've made over the years. I personally have had 3 injectors fail on me in the past 3 years as well as a regulator. It's probably just a combination of high pressure and old equipment, but I figured it was good enough to throw in there. Plus it makes putting a quality adjustable unit on the car more feasable.

[datsun2401972]

I didn't use the search engine, but I did peruse through the 180sx picture book fsm and didn't find standard and minimum compression test readings.

Seems like a good thing to have in the faq if you ask me.

[IanS]

I think to help clarify what oil to use you could add this picture to the FAQ thread, I pulled it directly from the FSM.

[Hijacker]

Got one better for ya Ian!



I like the idea, so I found an aligned version in my S15 SR manual

[IanS]

Well aren't you special.

[Hijacker]

I tend to believe I are, Braveheart

We are taking back 240 general, Im am assembling the post whores of old as we speak. Its time we showed all these newbs what we are made of.

FREEEEEEDOOOOOOOMMMMMM.

[CRyan]

Any info on the S14 SR to S14 chassis yet?

Like the S13 SR to S13 chassis type deal

Thanks
