Can someone tell me what are the oil presure readings- used the search tool, got for sale threads mainly.

Idle sometimes I see 15psi, sometiems 20
mid throttle: 45-60psi
full throttle: 80-100psi.

during warmup the guage reads 45-60psi.

by the way Im useing a Megan Racing guage, it was cheap, so yea are these accurate?

fyi all motors ahould have higher oil press when cold.

A good rule of thumb is 10 Psi oil pressure for every thousand rpm.

If you have at least this then your good.
:naughty:

The power specs, and turbo that Sequence Garage listed are for s13 sr20det only. S14 is 220hp (I think) with a t28 turbo. The s15 is 250hp (again, I think) and uses yet another turbo.

S15 same turbo with cast divider wall, bigger injectors, and I think thicker beams but not sure. Both S14 and S15 blacktops have VVL.

there..fixed it for ya...would really be a fun motor if they have vvl...but sadly they dont..so dont spread incorrect info.

At the bottom of this tread they talk about bhoost for stock sr20det turbo. I have found from personnal experiance that the turbo will at least put out 1.3mb, or 18 psi, but I have stock everything, so detination was the final outcome, but it would put out more if you had bigger inj, front mount IC. I'm running it at 14 psi right now with no problems. Thats with a greddy boost controller.

Z32 NA and TT AFM look the same but are different. The difference is that the NA AFM will read up to 350hp or so, the TT one will read up to 500hp. You want the TT AFM.

your dumb as shit and your post should be removed at once, and when yours is, then mine should follow

btw I see you dont post much as youve been here quite a bit longer than your post count would show, I hope this doesnt discourage you from future posting, but I would hope you think next time before pushing bullshit into the mix.

Hey f$%K you you yanky piece of crap, when you turkey's were still running around in ka truck engine pieces of crap we'd been doing sr conversions etc here for years, (and had complete import s13 sr's here). There are 2 part numbers for Z32 AFM 1 for NA and 1 for TT. They have been tested for voltage to airflow capacity and that's the fact jack, so unless you have been involved intuning them and have the facts shut your stupid dumb shit mouth.

What's with the hate? It takes maturity to engage in intelligent discourse without namecalling. If someone says something you disagree with, make it known WITHOUT taking personal jabs. Didn't either of you two go to Kindergarten? Sheesh. :rolleyes:

http://www.courtesyparts.com/Merchan...e=22680-Z32ALL
Apparently the Z32 MAFs have the same part number and are therefore the same for both the TT and the N/A (at least for the USDM, although I highly doubt it would be different elsewhere). So calm down you two! :spank:

Oil Capacities
 

wow.. i think this is my first post ever.

This info is for the S14 blacktop motor, it's taken right out of the service manual. hope this helps some of you.


Engine Oil: (with filter change): 3 1/4 qt (3.7 L)
(w/o filter change): 3 1/8 qt (3.5 L)

Cooling System (including resevoir): 5 1/2 qt (6.2 L)

Manual Transmission: *GL-4* 4 1/4 pt (2.4 L)
Differential carrier gear oil: *GL-5* 3 1/8 pt (1.8 L)

Automatic Transmission: 7 qt (7.9 L)

Power steering 3/4 qt (0.9 L)

edit: if anyone doesnt believe this I can back it up with a pic of the page from the manual, but as you can tell I'm new and don't know how to upload pics yet... unless theres someone that can host them for me.

short block has no Head only pistons crank ect

I just found out the hard way that there is a difference between FWD and RWD seals for the SR. RWD are larger.

sr20det spark plugs are code BKR7E-11

by NGK

heres a few had to search for the clutch and main seal that any us cars have...

-Front and rear main seal = 93 sentra SER
-Stock sr clutch = 89 Nissan Maxima
-Timing chain replacement = 89 Nissan Maxima
-o2 sensor = 87 300zx turbo
-Turbo gaskets = 90-96 tt 300zx
-Exhaust/intake manifold gaskets = 93 Sentra SER


Also found out you could use a ka radiator on sr but you need a top radiator hose that would travel from the pass side to the driverside and you will need to cut the ends a bit..

you can get the hoses from the following

-02 Dodge neon L4 2.0L
-96 Buick road master limited V8 8.7L
-96 chevrolet caprice classic V8 4.3L/5.7L

The Japanese S14 and S15 turbo are basically the same. Both the compressor and exhaust housings are the same. The compressor and exhaust wheels are the same specs. The difference is that the S14 exhaust wheel is not made of the same material as the S15 exhaust wheel. I can not remember the materials, but they are NOT ceramic, they are steel alloys.

The S14 turbo in Australia is not ball bearing from what I have been told. The S15 in Australia is ball bearing though.

The spark plug seals are not the same. The S13 and S14/15 RWD SR20DET spark plug seals are JDM only.

The SR and KA bell bousing have different engine side bolt patterns.

DO NOT POST IN THIS THREAD UNLESS YOU HAVE AN ANSWER TO A FAQ!

I just pruned ~40 posts from this thread, too. I'm sick of fucking babysitting these FAQs, and WILL lock them if a simple rule like "Stop asking stupid questions" can't be followed.
You have a question without an answer? Step 1. Search. Step 2. Post in the Tech section, NOT THE FUCKING ANSWER THREAD!

sr20det s13 in s14 coolent capacity:
"with koyo s14 radiator"

1 3/4 gallons


thats all i got...

did a search and found nothing

sr20det oil pan holds 3.5 quarts of oil but you can put in four.

>>don't know if thats a good or bad thing but i remember it being discussed.<<

do not put anymore than 3.5 quarts of oil in your sr.. the rest will be spit out by your engine through your breather valve, unless you like your intercooler and intake to have a thick oil film on the inside.

yes it will hurt your engine.

s14 sr into 96 240sx help
 

Hey, I am doing an s14 sr into s14 96 240sx and I have the complete wring harness and the jdm ecu. There are four plugs on the inside-of-the-firewall end of the harness, the ecu plug, another large plug (which is obvious where it goes so ok), and then 2 blue relay plugs. On the 240sx harness though there is one blue relay plug, and then this 8wire little white plug that attatches to a plug that seems to run to the back of the car. What to I do with this difference? I found which of the 2 relay plugs match up, but I am left with an unaccounted for relay plug on the sr harness and a empty white plug in the car. what should I do?

Those sparkplugs fit but aren't OEM and are one step colder than stock.
Be sure you regap them to 0.9mm (0.036in).

The correct OEM plugs are double platinum:
NGK PFR6B-9
And I think this is the Nissan Part Number:
22401-27N66

You can also use NGK Iridium:
BKR6EIX
BKR6EVX
BKR6EIX-P

Or traditional spark plugs like he listed:
BKR6E

You can change all those sixs to sevens to get colder plugs.
(e.g. BKR7EIX)

-incase of hotpipe clearance issue
to add; If you want your SR hotpipe to sit LOWER(S13 SR), use a S14 turbo inlet pipe..
hotpipe /w bov sits nice and low.

s14 inlet pipe is shorter then s13 inlet pipe.

This is a diagram I made for converting your your #62 harness to work with a J4 ECU, and visca versa.

it illustrates the differences between #62, E5, and J4 ecus.very handy!

Does this thing have that solenoid?http://rhdjapan.com/images/ebaypics/...p/DSC00080.JPG

I think with the NGK plug the higher number you go the colder the plug gets. example hotter - bkr6e ; colder - bkr7e Correct me if I'm wrong guys

we've already discovered this...delete my post and his please

i have a real quick question ive been wonderin about for a long time... how much does a SR20DET weigh in a base model 240sx?(no power windows,sunroof,etc.)

thanks.
