Classified Forums - Read this first!

Here are a few simple guidelines for this forum. Failure to follow any of these rules will be grounds for your thread to be closed.

Post your information
Post as much info as you can. Say where you are located, where the part is located, the best way to get in contact with you, if you are willing to ship, etc.

Post the item's information
Post as much info as you can. A price must be posted, as well as pictures of the item(s). Post as many pictures as you can, even if it is a common item. A picture tells a thousand words, but it can also conceal another thousand. Links to hosted galleries of images are acceptable, links to eBay and/or Craigslist are not. Once the item sells, please do not edit your ad to remove the price. Many people search through old ads to get an idea what their item may be worth.

-Post where you are located and if you would prefer local pickup.

In case the point was not made, everything being sold on this forum must include a price and as many pictures as possible.
-This is not eBay or Craigslist (or any other buy/sell/trade site). Do not post links to those for your ad. The same goes for linking to ads on other forums... either post your information here or have your thread closed.
-Feeler threads are not allowed. If you're not sure about selling it, don't post it.
-Cross-posting within the R3VLimited forum is not allowed. Choose a single subforum for your ad.
-If listing your item for trade, post what you are looking for, what you feel your item is worth, if you would like cash back or if you have cash to put on top.
-Thread crapping is not allowed. If you're not interested in purchasing the item for sale or have nothing positive to add, stay out of the thread or be prepared for a time out. If you complain about the time out, it will be extended.
-Threads can be bumped a maximum of once per day (24h). You are allowed to respond to others more than once a day.

    Dederic Motorsports Complete Bolt-on Turbo System

    Price:Production Temporarily Halted

    e30 m20b25 Promotional Bolt-On Turbo Kits

    This is a complete turbo kit, minus the exhaust. It bolts on. It fits.

    This turbo kit features a fully programmable Engine Management System (based on Microsquirt EMS) that replaces the OEM Motronic unit, which in turn provides quicker throttle response and more power than any stock ECU, piggy-backed or not. There’s no fooling the stock computer, no noisy fuel pumps, or no fuel pressure regulators straining your stock fuel system. Stainless downpipes and aluminum intake tube joints are TIG welded in house.

    This kit utilizes a medium front mounted intercooler, and removes the stock AFM converting from an Air-Mass system to Speed-Density type engine management. Boost pressure is set at 8psi. Aux fan is replaced with a smaller unit and AC is retained. Some minor chassis clearancing is required for intake tubing. Lifetime warranty on all fabricated parts (exhaust and intake tubing, all welds), 1 year warranty on all mechanical parts (turbochargers, BOV/bypass valves, wastegates, intercoolers, brackets and adapters), and 6 month warranty on all electronic parts (injectors, EMS units, wideband controllers). We will repair or replace any defective items at our discretion.

    This kit comes with a base tune, tuned for all components included in this kit and this kit only. Any changes to the kit components will require a retune. Expect about 90-110 whp and 100-120 wtq increase at the default 8psi setting using 91 octane. These are realistic figures based on many dyno tuning sessions on various m20b25s.

    Recommended Components (not included, but available for purchase): ARP Head Studs ($215) and MLS Head gasket ($220).

    Main Features:
    • Stainless Steel Tubular Turbo Manifold Adapter
    • Fully Programmable EMS
    • High flow fuel injectors
    • Front mount intercooler
    • Bypass/Recirc Valve
    • E30 Specific LC-1 Wideband O2
    • T3, GT3582 Turbocharger
    • Externally Wastegated
    • 3" Stainless Mandrel Bent Downpipe
    • V-Band Exhaust Flanges
    • 8psi Default, All other pressures available for +$30
    • Complete Bolt-On kit

    I'll now be including a set of 12.9 non-stretch headbolts with each turbo kit and instructions on how to properly install them.

    Availability: Made to order, 4 week production time.
    Total Price: $3000+Tax (sales in CA) and S&H

    : Took some photos for you guys last night...

    Products may change and vary as we are continuously updating parts to ensure the reliability of all components. The photos do not show an entire kit, just the main features :) enjoy.

    the first few plots was the car running no turbo, on stock everything. The big one was after the turbo install and some tuning. Notice how much smoother the car ran.

    This is our exhaust that works with our kit. 3" stainless mandrel bends, tig welded, with vbands.
    $650 straight pipe (base exhaust), Mufflers, resonators, and catalysts are extra (Market Price). Mounts to stock hangers.

    Shown below is $890, W/ magnaflow muffler and additional vbands. Mounts to stock hangers.

    Shipping is $75 to lower 48.

    I need to start looking for another platform, cause I really like the sound of this. I would be all up on this, but I'm still not 100% with my 2.8m20 build.

            I guessing that you have a eta? this is even better. when you put an i head on you have a 2.7 turbo stroker. that means more power with a eta then a is. were talking around 330whp. thats if you have 15 psi and do every thing right.


              Everyone love part porn, so post up some pics!

              What lb/hr injectors? Just a plain t3 flange on the header? Turbo map/moar specs?

                  Custom kit I had done by Derek @ DMS, of course with a few upgraded options.

                    the only reason to turbo a car, right?

                        will it bolt on to a regular 2.7?


                          Post some pics up plz...

                          And also does anyone else know how these compare to TCD turbos?
