I need information on nissan motors(besides rb’s):
What is the best turbo motor? What type Hp/Tq can be achieved from a 3k-4k build?
i know this is vage, i dont want to limit the input.
:inout::zong:
for cheap build just do a turbo KA
What are some numbers? I would like to see 400hp/350tq? Is the Ka good for something like this?
sure, but if your build doesn’t include any internal work i can’t say how long it’ll last… its like any other motor some people get crazy numbers on stock internals, others are not so lucky. but yes those numbers are definitely attainable from a turbo KA
If you don’t have a budget restriction, you could easily see those numbers out of a VQ.
KA is doable, but will require a bit more boost, I don’t think you’d have as much of a powerband.
this thread sucks.
yes, i would like a wide power band, something full spool by 2.1k, i know this is vage but i am tossing around some ideas.
thank you for your input. i thought your post would have had something other then that.
As far as im concerned, the KA should have never been boosted. Just an ugly looking engine. If you can get your hands on a cheap CA18DET you’ll have better luck. Internals already forged and cylinder head design is very good. Just becoming hard to get good tunign parts now. Tomei for the last couple of years have stopped making cams and many other makers too.
That is some good information, what is this SR swap motors that people put in thier 240’s?
If you’ve never heard of an SR20, you need to do some reading.
For reference there is a CA18 build going on in the DIY section here. IIRC it’s Articzap’s thread.
you don’t even know what the sr20det is? you need to do some more research 
www.freshalloy.com www.zilvia.net go do some reading, you’ll find info on all of your options there 
only looking for 4 cylinder motors? …not willing to look into a V6?
3-4k budget
400rwhp/350tq
Fully spooled by 2100rpm
It’s just not gonna happen man. I’ve tuned many many different Nissan setups and you’ll have a better chance of finding Nessie than building something that does all three of these requirements.
just a quick copy and paste for you of the stock form of the 3 main sr20det’s… and no, that budget/full psi/power expectations don’t seem likely.
hope this helps.
any info on what you’re planning to do with this? what shell are you planning to put it in?
SR20DET Specs
Here are some basic SR20DET specs showing the differences between the S13, S14 and S15 engines. There have been basically 3 generations of the SR20DET. Which one is better, it doesn’t really matter, especially since there are very few engines out there that will be left stock for very long. Most customers will install them as stock as possible, but will soon upgrade fuel, turbo, intake, and intercooler, if they have not done so already when they order a conversion package.
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

I don’t think the stock turbo in my car even spooled at 2.1k, and the things tiny…
400 hp off an SR20 will cost more than that
k03 doesn’t even hit it quite that low. more around 3k.
thanks for the information
yeah, but no numbers.
will read them tonight
never really thought about it. any build numbers?
yeah i was was just putting numbers out there.
yeah, now that i think about it it might be 3k, i was thinking about my superduty and it spooled quick
