This is a brand new set of custom aluminum built TD04 draw-thru maf pre-turbo pipes. This replaces the stock rubber intake pipes for your turbos on your 3000GT VR-4 91-99 or Dodge Stealth R/T Turbo 91-96. It does not include any hose nipples on the front or rear intake pipes because 98% of people modifying these cars simplify the setup and do a vacuum reduction(google 3000GT vacuum reduction 3s wiki) in order to run 3-4 total vacuum lines vs a huge mess/tree of vacuum lines everywhere. Please see the pictures for ideas on fitment and modifications. These work great for side mount intercooler cars as well.
Benefits include smooth airflow through the 2.5" mandrel bent aluminum intake pipes vs rubber ribs on the factory turbo intakes. There is a major restriction on the factory rubber pre-turbo pipes. The inside diameter is 1.75” at the turbo tapering to 2” at the rubber Y. These intake hard pipes are 35% larger, increase power, and make your turbos significantly louder where you can hear the turbo spool very well. It is not obnoxious at all and most people prefer to hear the turbos sing. You can expect up to 30-40whp gains with an upgrade MAF sensor and bigger bolt-on 15G or larger turbos pushing 400+whp due to much less intake restriction.
There is no reduction in pipe diameter as these are 2.5" all the way through and are the only ones on the market to give unrestricted flow to the 2.5" anti-surge compressor housing Arashi and Kinugawa turbos. These are an excellent upgrade that can grow with you as you move from a mild stock 9b turbo 1.75" inlet to DR-750, 20T, and the newest bolt-on 21H turbos all with a 2.5" inlet for 700+whp capability with supporting mods.
Pictures are included to compare them against the brands that have been available over time. Currently, only china made pre-turbo pipes are available from vendors and they leave way too much to be desired with poor fitment and quality. These are made in the USA and follow a better bend design that actually fits nicely. Quite a few of these are out there with no issues.
Because of all the various turbo configurations and sizes, couplers and clamps are not included. You will need reducer couplers that can range from 2.5" to 1.75" for stock turbos. 20T or 21H anti-surge turbos require 2.5" straight couplers. If you have something inbetween, please measure your turbo so you can get the proper side coupler in the color desired. Pictures are included of a stock turbo for size reference as well as the factory intake pipes to give you a comparison.
This listing includes a set of front and rear TD04 intake pipes as seen in the last picture. If you are planning on deleting the maf sensor with the appropriate engine management setup, please see my other listings for both TD04 and TD05 speed density intake pipes.
These are built in the USA by a long time 18+ year enthusiast/owner so if you have any questions at all about the product, modifications for your build, or perhaps even some custom fabricated parts, just send me a message. You can find me on 3SI forum and Facebook groups as well building quite a few more custom products for these cars.
