Start it. I will delete unnecessary and off topic posts.
This thread should be something along the lines of how hard is the swap, what's required. Power level stages, build ups, cost tally, and power levels. Warnings and things to watch out for during swap, mods.
I figure this will save alot of heartache as noobs can read this thread and not post stupid questions.

heres a few basics...

stock boost IS 11lb's
boost w/o solenoid 7lb.
do not boost stock s13 t25 over 14lb. it's useless.
12's are possible on stock turbo

Specifications for the Red Top SR20DET
(Found on the 91-93 180SX & Silvia)

• Displacement: 1998cc (2.0 liter)
• Cam Type: DOHC 16 valve, chain driven cam sprockets
• Bore & Stroke 86mm x 86mm
• Compression: 8.5:1
• Horsepower: 205ps @ 6000rpm
• Torque: 203 ft/lbs @ 4000rpm
• Stock Boost: 7 psi
• Throttle Body Bore: 60mm
• Injector Size: 370cc/min
• Turbo Specs:
• Compressor: T-25, 60 trim 56mm BCI-1 compressor.
• Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.
• Center Section: Journal bearings
• Performance:
  The stock turbo will be safe to 13-15 psi. After that, the turbo is past its efficiency range, and power increases will fall off and are not worth the risk of turbo damage. The engine should produce 230-250 RWHP at safe boost.

Specifications for the Black Top SR20DET
(Found on the 94-98 180SX)

• Displacement: 1998cc (2.0 liter)
• Cam Type: DOHC 16 valve, chain driven cam sprockets
• Bore & Stroke: 86mm x 86mm
• Compression: 8.5:1
• Horsepower: 205hp @ 6000rpm
• Torque: 203 ft/lbs @ 4000rpm
• Stock Boost: 7 psi
• Throttle Body Bore: 60mm
• Injector Size: 370cc/min
• Turbo Specs:
• Compressor: T-25, 60 trim 56mm BCI-1 compressor.
• Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.
• Center Section: Journal bearings
• Performance:
  The stock turbo will be safe to 13-15 psi. After that, the turbo is past its efficiency range, and power increases will fall off and are not worth the risk of turbo damage. The engine should produce 230-250 RWHP at safe boost.

Specifications for the S14 Black Top SR20DET with VTC
(Found on the 95-98 Silvia)

• Horsepower: 220hp @ 6000rpm
• Torque: 203 ft/lbs @ 4800rpm
• Turbo Specs:
• Compressor: T-28, 60 trim 60mm BCI-1 compressor in T-04B housing
• Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.
• Center Section: Ball Bearing
• S14 SR20DET's use a different ECU and harness, these are extremely expensive and hard to find.
• Variable valve timing system and a different turbo are the significant changes from the S13 SR20DET engines.
• The S13 uses a "low port" intake design vs. the S14 "high port" design.
• Performance:
  The stock turbo will be safe to 13-15 psi. After that, the turbo is past its efficiency range, and power increases will fall off and are not worth the risk of turbo damage. The stock engine should produce 250-260 RWHP at safe boost using stock turbo. Upgrading turbo, fuel and rest of need parts will yield 300-375.

Specifications for the S15 Black Top SR20DET
(Found on the 99+ Silvia)

• Horsepower: 250ps @ 6000rpm
• Transmission: 6 Speed, Close Ratio
• Injector Size: 480cc/min
• Turbo Specs:
• Compressor: T-28, 60 trim 60 mm BCI-1 compressor in T-04B housing
• Turbine: Inconel turbine wheel. Cast divider wall between turbine discharge and wastegate.
• Center Section: Ball Bearing
• This engine is expensive and hard to get. If you are on a tight budget, please consider other options as the money you save from buying this engine can be better used to build up a really nice red top.
• Additions: 6 speed manual transmission. The 6 speed cannot be used on the S13 and S14 motors, and uses a different driveshaft. Speed sensor is located in the differential. The 6 speed is cool, but is not as strong as the 5 speed from the older cars. There is basically 6 gears inside the same housing that was designed to hold 5 gears. This makes the gears smaller and weaker, therby breaking more often.

Usefull info ive used threw out the years and got saved in a folder. Thought it would be useful for some if i dropped it in here.

Water Temperature Sensor
Sentra - Goes according to what year your SR is.
Differences are in 91-94 and 95-98
Sentra: 91-94 have a rectangleish plug while 95-98 have a slightly slimmer, more box looking plug.
Redtop and midyear S13 blacktops use a z32 sensor. I believe you should go by year as well if buying a Z32 sensor.
Late S13 blacktops use the Sentra sensor.
KA water temp sensor doesn't work, or at least it didn't for me. (S13 98 Blacktop)

S15 Exhaust Manifold Gasket

The 11lbs without a solenoid thing for who wanted it explained. There is a solinoid that actuates the wastegate, but to my understanding doesn't come with the SR motorsets, because it's mounted elsewhere in the engine bay. So you'd have to get one, use a boost controller, or run the vaccum hose from the nipple on the intercooler directly to the wastegate, bypassing the valve function. Without this solenoid it should run 11lbs.

DuffMan

No its still 7psi. Think about it: A valve that restricts air to the wastegate can only raise the boost not lower it. So if the stock wastegate was really set to 11psi, theres no way a solenoid would bring it down to 7psi. The purpose of the solenoid is slightly faster spool up, by preventing the wastegate from opening part way at lower boost.

kazuo

Bingo, you win.

That's exactly why I asked him what he talking about... didn't make any sense at all.

Pepperoni: Can you be a bit more specific on the water temp sensor interchangeablility? Not only for the FAQ, but also for myself... I think I may need one and I can't figure out which one I need from your post (Z32? It's for a redtop :P)

Also does anyone know about fpr interchange? Seems like the KA one would fit, just that the nipple for the vac line is on a different side...

neilsan

Does this thing have that solenoid?

mjjstang

for those of you who have done you own wiring of harnesses, I have a couple of questions because I dont want to fry my electronics and have to work even more for more money,

since HT is down I cant use that right now, I foudn a way to go there but pics dont work,

wehn I splice the connectors inside the car, I cut the white one off the sr, and splice the brown one from the ka, right? this is confusing me so much because there is also a white connector on the ka, and it is the same exact connector on the sr harness, that I cut, only the wires dont match, but the wires on the brown one do.

2. the old ground wire from the battery has it grounded to the intake manifold and to the chassis, my wire is falling apart so i want to put another one i have on, can I go just directly from the battery to the intake manifold or do i also need it grounded to the chassis,

3. the ground wire that comes from the ignitor, does this ground to the chassis,


ok I know your probably sick of my questions and so am I, this is probably all the wiring questions I will have, and I know alot of people here have done their own wiring so it shouldnt be too hard to answer right? thanks for any help though.

No lines going to the wastegate would mean that the turbo isn't regulated, and would run to 15-18psi, wherever the turbo stops spooling at on an SR. It would go way out of efficiency and cause detrimental damage.

Sr blocks are alum, with steel sleeves.

Sr intake manifolds vary. S13 has a long runner manifold, and s14 has a short runner. You can tell the diff, because the s13 manifold has the throttle body under the manifold, and s14 has it about even with the height of the valve cover.

Sr blocks use the upper oil pan for block reinforcement.

Sr20det motors really need an oil cooler. (track)

Oil Filter: Pull off the intake manifold support brackets under the manifold, or you will wish you never had to change your oil again.

sr20 motors dont like ka fuel filters (z32)

Dont raise the boost unless you have an aftermarket fuel pump.

Sr20det trannys are weak.

S15 trannys are even weaker.

Keep your ignitor away from heat (exhaust manifold)

When setting ignition timing with a light, timing marks on crank pully may not be accurate unless you zero the cas (cam angle sensor).

Invest in rocker arm stoppers.

T25 turbos suck.

You better do a good job rerouting the coolant line behind the head for the turbo. Because changing it while the motors in sucks.

ehh.

__________________

cobras89

correction: only remove the intake manifold support bracket if you are going to remove the oil filter from underneath the car. if you want to go from up top and save a lot of time. buy a oil filter cap wrench and use your socket wrench to twist it off. now you wont have to wish that you never had to change your oil again.

TPS and/or Temp. Sensor interchange, anyone? let's not hijack this.

- this is general for 89-98 Nissan but most apply to the SR20 motor.
- to set car into diag. mode, with the key in the "ON" position, turn potentometer screw on ECU fully clockwise, then turn it fully counterclockwise. The LED on the ECU will begin to flash.
- first digit = LONG blink; second digit = SHORT blink (ex: 1... 1... 1... 1... then 1-1-1 equals 43 = TPS)

Hey i have a 89 se coupe converted to rhd. Has a black top sr20 in it. Upgraded injectors 550cc, 255 walbro fp, fuel pressure reg, t28 s15 turbo and z32 maf the kid i got the car from says it's stock ecu i don't seem to beleive that because it wouldn't run from my understanding, i smell it running rich it's 3in exhaust from turbo back no cat megan exhaust. I'm trying to figure best ecu for it incase i pull this apart and it does have stock ecu in it. I need to get it tuned here in the midwest. The car runs good no issues at all so hell i dunno.. Any help would be great, i was a honda kid for awhile and my cousin let me drive his s14 silvia and i fell inlove and bought a s13. Thanks guys!

ultimateirving

Open up the ECU and you can tell if its been chipped or not. easiest way to tell

ok...my official correction of my previous statement. After checking the lines more closely and doing more research...hooking the line from the wastegate to tb will get you 7lb. hooking the wastegate to the solenoid then to tb does what has been said....it actually restricts the airflow and brings you to 11lb....no vac on wastegate does indeed give infinite boost (not good)....thank you guys for questioning me and helping me learn and not treating me like a dumbass...you guys are awesome....yet again proves....this is a great board! Keep up the good work!

Oops, sorry kazuo, didn't keep up with the thead.
Water Temperature Sensor (cont..)
I know for sure the sentra one works because thats the one I used for my S13 blacktop. Since i have a 1998 blacktop, i used a 1998 Sentra temp. sensor. Im not sure if redtops and blacktops are the same when it comes to temp sensors, but you can try out a sentra one. According to a friend online, he said he used a Z32 sensor for his redtop; and it goes with year as well, like i did with the sentra sensor. So, you should be able to use a Z32 '91 temp sensor for your redtop. KA's may be the same for redtops, but thats only a guess; KA was different for mine. I can only assure you about Sentra sensor for S13 blacktops.

For the water temp sensor, atleast for my S14, have to use the stock KA sensor off my 97 KA. I forgot bout this and my temp was pegged at H for awhile till i talked to Phase2 and they told me to swap out the sensor off my KA.

When you go to get parts (IE oil filter, plugs, etc) ask for 91 Nissan NX2000
It has the same sr20de.
