1. Which BMW models and years does this T4 turbo kit fit?

This kit is listed for many BMW inline‑6 applications: E36 325i/325is (1991–1995), 328i/328is (1994–1999), 323i (1995–1999), M3 (1992–1999); and E46 323i/323is/323Ci/323Ti (1997–2000), 328i/328Ci (1998–2000), 325i/325Ci/325Xi/325Ti (2001–2007), 330i/330Ci/330Xi (2000–2007). It is also described as suitable for many 4–6 cylinder applications, but fitment can require manifold/exhaust modifications for non‑listed engines—verify measurements before purchase.

2. What is included in the kit?

The package includes: T3/T4 turbocharger, intercooler (27"x7"x2.5" core 21"x7"x2.5"), turbo piping kit with aluminum pipes and silicone hoses, Type‑S blow off valve and adapter pipe, 35/38mm external wastegate, turbo boost controller, stainless braided oil feed/return lines, 5‑bolt T3/T4 turbo exhaust pipe, T3/T4 manifold (with wastegate flange), and an intake air filter.

3. What are the turbocharger specifications?

Compressor inlet 72mm, outlet 53mm; turbine inducer 64.8mm, exducer 55.8mm; turbine A/R 0.63, compressor A/R 0.5; turbine trim 74.2, compressor trim 48.1; wet float bearing; turbo overall size ~270×220×220 mm; exhaust inlet manifold is T3/T4 4‑bolt and exhaust outlet is 5‑bolt.

4. What boost and power levels can this kit support?

The turbo is advertised for a practical boost output capability of roughly 7.5–14.5 psi for typical applications and up to 21 psi (1.5 bar) in some setups. The small intercooler supports up to ~350 hp; the BOV claims a high clamp rating and the boost controller is rated up to 30 psi. Realizable power depends on engine, fueling, fueling system, tune, and supporting mods.

5. Is an ECU tune required?

Yes. Installing a turbo of this size will require proper engine management/tuning (standalone ECU or piggyback + professional tune) to adjust fueling, ignition timing, and boost control. Running increased boost without tuning risks engine damage.

6. What additional parts or modifications will I likely need?

Common additional items: upgraded fuel injectors and pump, ECU tune, oil feed source and return fitting if not already present, appropriate downpipe and exhaust modifications to mate to the 5‑bolt outlet, stronger clutch (for manuals) or consideration of AT torque limits, and possibly larger intercooler depending on target power.

7. Does the kit include oil feed and return lines?

Yes. A stainless braided turbo oil feed + return drain line kit is included to circulate oil between the turbo and oil pan. Proper routing and a secure feed source from the engine are still required during installation.

8. What type and size is the intercooler and piping?

Intercooler size is 27" x 7" x 2.5" (core 21" x 7" x 2.5"). Inlet size is 2.5" and the piping kit includes multiple aluminum straight and angled pipes, six 2.5" straight silicone hoses, two 2.5" 90° hoses, and sixteen 2.5" stainless steel T‑clamps.

9. What wastegate and BOV are supplied?

The kit includes a 35/38mm external wastegate (with mounting flange on the manifold) and a CNC billet Type‑S/RS style blow‑off valve with a 2.5" flange. The manufacturer states high capacity for the BOV; proper tuning and boost control setup are still necessary.

10. What flange configurations does the manifold and turbo use?

The turbo/manifold uses a standard T3/T4 (T03/T04) 4‑bolt inlet flange and a 5‑bolt exhaust outlet flange for the supplied 5‑bolt turbo pipe. The manifold includes a 35/38mm wastegate flange.

11. Will this kit fit both manual and automatic transmissions?

Mechanically the kit can be installed on vehicles with either transmission type, but transmission and driveline limits (torque capacity) differ. If target power increases substantially, you may need upgrades (clutch for manuals, torque‑handling considerations for automatics).

12. Is professional installation recommended?

Yes. Turbo installations require mechanical and tuning expertise (oil/coolant routing where applicable, exhaust and manifold fitting, boost controller setup, and ECU tuning). Professional installation reduces the risk of leaks, oil starvation, and engine damage.

13. Does this kit come with warranty and is it street legal?

Warranty and return policies vary by seller—check the seller listing for warranty details. As for legality, forced induction and emissions equipment changes can affect emissions compliance; verify local laws and inspection requirements before installation.

14. Can I use this kit on 4‑cylinder BMW engines?

The turbo unit and piping are described as suitable for many 4–6 cylinder applications, but manifold fitment and exhaust port compatibility differ between engines. A custom or specific 4‑cylinder manifold/adaptor may be required. Verify flange, header, and spatial clearances for your engine.
