Plan your SR20DET tuning project carefully, decide on your power target and then uprate the components to get your there.Įxhaust and fuelling upgrades are a good base to start with, but you’ll not notice much more power until you start tweaking the boost and timing. You should ideally optimize your engines power to your preferences so for a car used daily stick with a shorter duration SR20 DET cam Race camshafts, increase the high end rpm power band but as a result the car will not idle smoothly and low end power nearly always suffers.Ī Motorsport cam will just annoy you whilst in heavy traffic. Avoid pairing a light weight single mass flywheel with an aggressive cam profile or you’ll end up with a very lumpy engine.įast road camshafts normally increase the bhp and torque throughout the rpm range, you could sacrifice a little low down bhp but high end rpm power will be higher. The cam profile makes a large difference and fitting vernier pulleys will allow fine control and put the power band exactly where you need it to match your gearing.
Choosing a higher performance camshaft profile raises the bhp accordingly. When talking about the best best for your SR20 DET engine, we are going to concentrate on the upgrades that give the best value for money.Īltering your SR20 DET camshaft will make a dramatic difference to the engine bhp.
SR20DET BOOST GAUGE KIT UPGRADE
Is the car going to be used as your daily drive or is your desire for a competition ready car? If you do your upgrades in the right order you’ll keep the car drivable and can spread your upgrade costs. Plan your power targets before you begin. The stock engine will reportedly tolerate power figures of 350-400bhp with some reporting failures of the sleeves around 475bhp indicating that some lucky owners have a block which can cope with more than 400bhp reliably. 1995 saw the “bent cam” (named after the curve of the rocker cover at the back which makes it look bent) introduced on the 200sx which saw the introduction of variable valve timing control VTC but also nicknamed VVT in some regions, addition of the Garrett T28 turbo and uprated injectors. Later engines are always an improvement over earlier models, with various revisions and enhancements introduced.
SR20DET BOOST GAUGE KIT MANUAL
S15 Black top - VCT, 6-speed manual transmission (Garrett Journal Bearing T28 for Eu and Australia and Ball Bearing T28 turbo for Japan).S14 Black top -Variable Cam Timing or VCT was introduced on the intake cam (Garrett T28 journal bearing turbo for Australian and Eu markets and Garrett T28 Ball Bearing turbo for the Japanese market 370cc injectors were used.S13 Red top - (Garrett T25G turbo) 370cc injectors were used.Most of our members are looking to add parts over time rather than take the car off the road for 6 months for a complete overhaul and the SR20DET is able to offer this upgrade route. If you just want a cheap easy large power boost on your standard SR20DET tuning project, all you have to do is fit a boost controller and nitrous kit. Most people see power figures of 300bhp on stock internals with relatively simple turbo and fuelling upgrades.
It was fitted to a wide range of cars and is frequently used in motor sport applications. Later the engine was rotated to a longitudinal setup which work best for the many rear wheel drive cars Nissan planned to produce.
Production started in 1989 where it was insitially transversely mounted. The SR20DET is a fantastically tunable engine from Nissan and is extremely strong and reliable.īased around a light alloy block with alloy heads the twin cam setup uses tried and tested parts and the relatively recent T28 turbo and intercooler made the engine stand out among it’s peers.
SR20DET has lots of potential for your tuning project."
