You will proceed to remove the OEM Turbo Inlet Pipe (TIP) from the vehicle in the coming steps

These instructions are for OE intake. Other intakes will be similar

Use a 5.5mm socket and 1/4" ratchet to remove the two (2) clamps (red markups) securing the accordion style intake air tube

Remove intake air tube from car and set aside

Remove two (2) screws from Turbo Inlet Pipe (TIP) EVAP valve with T30 Torx Bit

Pop both EVAP lines from clip

Tuck EVAP valve out of the way as shown (blue box)

Use 10mm socket and ratchet to remove bolt from TIP bracket near inlet

Pull up on reservoir to free from bracket and relocate as shown

Use 10mm socket and ratchet to remove two (2) bolts from vacuum bracket

Use 10mm socket and ratchet to remove two (2) bolts from wiring loom cover

Unplug waste gate actuator by pushing the very top of the clip in with one finger and pulling the plug out with the other hand

Set wiring loom out of the way

Use pliers to slide the two (2) hose clamps down the rubber hose

Twist each hose to break adhesion to metal tube then and pull both hoses off

Use hose pliers if you have them, it's easier

Use caution to avoid tearing rubber but it can take some force to free hoses

Set hoses out of the way

Use caution not to bend or damage A/C line while removing TIP

Be careful not to damage A/C line

Remove bolt with 12mm socket, 3" extension, and ratchet

Remove nut with 12mm socket, 3" extension, and ratchet

OE Turbo Inlet Pipe will wiggle freely now

Unfortunately Honda used a single use hose clamps for the turbo inlet pipe. These are difficult to remove

Use caution not to damage rubber lines. This is tricky

You can use a grinder, Dremel, or perhaps even shears to remove this single use clamp. We prefer Dremel

Remove Clamp Shown

Partially cut through band of clamp. The idea is to remove enough material that the clamp will break

Place flat head screwdriver under cut. If cut enough band will break pretty easily with a bit of pressure

Pop crank breather hose off

Use caution as you proceed to minimize coolant leaks

Pinch off coolant line in a manner similar to what is shown

There are various other tools and ways to accomplish this, like pinch pliers

Put towel under coolant line to catch leak

Use pliers to slide clamp out of the way as shown

Remove rubber upper coolant feed hose from the TIP hard line

Place towel under the other end of the same line. Slide clamp (blue box) up hose using pliers and remove rubber hose from hard line

Plug coolant line attached to TIP with finger while removing TIP so as to avoid further coolant spills

Remove OE TIP from car and set aside

Loosening this bracket will help avoid scratching 27WON TIP during install

Use 10mm socket and ratchet to remove three (3) bolts shown

Move Vacuum bracket out of the way as shown

Use caution not to damage the rubber fitting. This is tricky

Remove Clamp Shown

Partially cut through band of clamp. The idea is to remove enough material that the clamp will break but not so much to cut into the rubber

Place flat head screwdriver under cut. If cut enough band will break pretty easily with a bit of pressure

A different clamp is shown but the process is the same

Place screwdriver as shown. Twist and pry while working around the perimeter to break seal and back rubber off the TIP a bit

Pull breather hose off OE TIP

Orientation of the breather hose assembly is important for ease of reinstallation

Place breather hose assembly on 27WON TIP as shown

You can cut-off the square nub or leave it on

Orient the 32-37mm Hose Clamp as shown and make sure it does not rest on bead roll

Slide these two (2) clamps up the Bypass Valve and Vacuum line hoses using needle nose pliers

It's helpful to twist rubber hose with hose pliers or by hand before pulling. This will break the seal

Pull Vacuum bracket assembly from the car

It's helpful to twist rubber hose with hose pliers or by hand before pulling. This will break the seal

Place 11mm spring clamp on silicone hose as shown

Spring clamp should slightly depress the silicone hose

Plastic wire cover breaks easily

Use small pick to unclip six (6) clips as shown

Open wire cover and remove from car

Set plastic cover aside. It will not be reused

Pop both clips on wastegate actuator plug as shown

Remove plastic cover from plug

Clip provided Tee in place as shown onto the wiring you uncovered in Step 19

Slide provided heat shrink tube over wastegate plug and then up the wire towards the Wiring Loom T-Cover

Use heat gun to heat shrink tube. Part of the heat shrink tube should cover the Wiring Loom T-Cover as shown

OPTIONAL: Use electrical tape to seal the other ends of the Tee

A 10" cut of tape works well for each end

TIP: Electrical tape is stronger when it's not stretched

You can use heat gun to smooth out the tape as desired

Reinstall wastegate plug cover

Tight spaces. Use caution not to scratch the TIP during install

Place provided turbo flange gasket onto turbo as shown

Carefully move TIP into position on turbo flange. While doing that use finger to push down rubber hose to clear wastegate actuator

Various components will now be attached to the TIP before securing it to the turbocharger

Use pliers and OE clamp to resecure lower rubber coolant feed line to turbocharger

Connect upper rubber coolant feed line to hardline

Remove Vice Grips

Use OE clamp to resecure upper rubber coolant feed line

Use provided hose clamp marked 11-20 to secure OE rubber hose to the hardline

Use provided gasket and attach Evap valve to 27WON TIP using OE T30 hardware

Insert OE bolt into turbocharger as shown using 12mm socket and extension. Tighten to finger tight

Do not overtighten bolts

Plug in Wastegate Actuator

Place coolant reservoir back to its original position

OE Shown. 27WON SRI next step. Other intakes similar

Make sure each hose clamp is rotated so that that bolt doesn't poke hood

Unclip Lid of OE airbox

Install provided 27WON silicone

There will be some setting resistance as you close the airbox lid. You can slide the silicone further up the TIP as needed

Use provided 95-103mm T-bolt hose clamp on TIP inlet

Use provided 73-81mm clamp for OE Intake

27WON SRI shown. PRL intake next step. Other intakes similar

Make sure each hose clamp is rotated so that that bolt doesn't poke hood

Install provided 27WON silicone

Some repositioning of the SRI silicone and/or bracket may be needed when changing from the OE TIP

Use provided 95-103mm T-bolt hose clamp on TIP inlet

Use provided 70-78mm clamp for 27WON Intake

PRL intake shown

Remove PRL silicone to OE tip if still installed

Remove three (3) plastic clips securing PRL inlet

Remove two (2) bolts to mounting bracket using 10mm socket and ratchet

Push provided silicone coupler as far on the 27WON TIP as it will go and rotate it until the MAF end lines up with PRL intake

Pull silicone onto MAF until 1.25" remains on the TIP. Secure TIP with provided 95-103mm Hose Clamp as shown

The clamp is to the left of the bead roll and the edge of the silicone is right at the edge of the clamp

Make sure the bolt on the clamp won't poke the hood liner

PRL intake shown

Push PRL intake into silicone. Silicone May appear short as shown

Push intake and silicone together and secure with provided 73-81mm Hose Clamp

A small gap of 1-2mm is ok here

Reconnect intake bracket with two 10mm bolts using socket and ratchet

Reconnect Inlet with plastic clips

Clearance from 27WON TIP to hood insulation is minimal. Repositioning the hood insulation will add space. This step is optional

There is plenty of clearance between 27WON TIP and the metal hood behind insulation

This step requires a Riv-Nut installation tool with M5 adapter

Remove six (6) plastic clips that hold hood insulation in place using clip removal tool

Install six (6) M5 Riv-Nuts

Allow insulation to hang as low as possible

Install provided M5 cap screws using 3mm hex wrench

To get the best performance from your 27Won Turbo Inlet Pipe, we recommend a custom tune

A custom tune for your specific vehicle with your specific modifications will provide the best performance for your Civic/Integra and the location you live in

Lots of hoses were disconnected during this install. Any hoses with clamps removed during install should be properly secured. CEL Code P0088 or others is a clue a connection may be leaking

CEL Code P2565 could indicate a bad connection at the wastegate. Pull plug and clean connectors if this happens

This completes the installation of your 27WON Performance Turbo Inlet Pipe

We hope you were impressed with your 27WON experience and love your new TIP for years to come. Email us at sales@27won.com or call us at 571-271-0271 with any questions or concerns
