I just wanted to gather as much information as i could about intake manifold/ intake plenums for the SR20DET as i found it to be very interesting personally. I will provide product link info also an approx price. As i find it very interesting in both design and hopefully we can get some feedback also /. * will update more as i find more information PLAZMAMAN https://plazmaman.co...mid=302&cate=71 Price: $995.00 Suits S14 and S15 SR20DET engines Billet CNC base with hand made sheet metal dome Utilizes OEM long runners for strong mid range torque 20+kW / 30+hp gain with supporting modifications Uses Plazmaman billet throttle body, 60, 66, 72mm available Ram tubes optional The ultimate plenum for your SR20DET, simply bolt on, tune and make power! Ikeya Formula 4 Throttle Chamber http://www-en.ikeya-...ry/1983341.html\ Price : 3k Increased air mass flow by turbo tuning will become resistance if normal throttle and surge tank are used. From these reasons behind, - Review on the capacity and structure of surge tank to deliver the increased air mass flow to each combustion chamber effectively. - to stabilize the even air suction system to each combustion chamber by having quadruplet throttle. By solving these issues, it's made possible to produce smooth/ powerful force and torque in addition to clear engine responsiveness at high/ middle revolution range. Mazworx S13 SR20DET Hi-Port Intake Manifold Link: http://www.mazworx.c...e-Manifold.aspx Price: $1095.00 Recent tests showed a substantial power gain over stock manifolds with compromising low end torque. With its revolutionary CNC billet runners, full upper plenum, 90mm throttle body provision, IACV and vacuum ports makes it ideal and a must have for all high horsepower SR20DET applications. State of the art design for optimum flow. Also includes a Mazworx top feed fuel rail -10AN in/out. Fits both RHD and LHD configurations. Fits 14mm x 60mm injectors. Greddy intake manifold link: Ebay Price: $200-300 knock off $600-1200 genuine This one will be tricky to review or find information because this manifold is extremely common and is a realistic modication given its price its definately "bang for buck" out of all the manifolds. That and also the fact it looks 10x better than stock. Hypertune Nissan SR20 link: http://www.hypertune.net/ Price: $2800 The design process begins by assessing the original vehicle and engine characteristics, as a guideline for the products development. Considering our customers requirements and installation limitations, parts are designed and analysed using advanced computer software to produce prototypes for testing purposes. The characteristics of the intake manifold are developed to increase overall efficiency, particularly in the mid and high RPM range, whilst minimising detrimental effect on low RPM response. Consideration is made for modified engines (camshafts, turbochargers, etc.) to assure the products performance and suitability for high output applications. Initial designs are sent to our highly experienced distributors worldwide, for testing and refinement. Once the design has been perfected, manufacture of the production parts begins. MANUFACTURE Hypertune Intake Manifolds are manufactured using state of the art CNC machinery, and metal forming techniques developed in-house. The goals of the manufacturing process are: + faithfully represent the CAD designed and developed parts + produce a high quality, structurally sound and reliable product + maintain the fit and appearance expected of a class leading product To maintain accuracy of critical dimensions, the entire intake runner is CNC machined to accuracy within .005mm. This tolerance is well beyond the capabilities of most porting services, and guarantees that your intake manifold will be suited to the best prepared cylinder heads. Although this process is very time consuming and expensive, we believe it is the only way to achieve perfection on a part that is critical to the performance of the intake system, and often difficult to prepare by hand. Plenum chambers are produced using a unique hydroforming process, developed in house. This allows us to produce a light weight, structurally sound part, with smooth surfaces for maximum flow potential and good appearance. The manifolds are finally welded and assembled by true craftsman, who pride themselves on producing some of the highest quality and most unique products in the industry. We recommend that this manifold be ordered with a 77mm throttle body flange. It can also be ordered with a 90mm flange for high-power applications. Currently, this product is only offered in a 4 injector configuration. It is designed to suit 11/14mm top-feed injectors and must be used with a Hypertune fuel rail.

Grant McGrath posted a topic in Nissan Silvia (nissansilvia.com)I am looking at coil overs for my 200sx S15. I've got between 1500 and 2000 to spend ide rather spend less if I can but I do wont good parts. It’s not a track car but would like it to really handle! And not EXTREMLY bumpy but don't expect it to be to smooth either! Any info that could help me out would be appreciated cause I’m reading about some and I can’t tell what my car needs/suits?
