This is by no means perfect but will hopefully provide to be useful for any frequently asked questions about installing a front mounted intercooler to a Peugeot 306.

Please feel free to provide any questions and/or answers and I will move them to the top of this thread so they can be reviewed easily.

____________________________________________

#1.
Q) What does "FMIC" & "TMIC" mean?
A) FMIC stands for "Front Mounted InterCooler". TMIC stands for "Top Mounted InterCooler".

_____________

#2.
Q) Why would I want to fit a FMIC?
A) By installing a FMIC your car will be able to provide a more air dense intake charge to the engine (colder air = denser air). This means that more air and fuel can be combusted per engine cycle therefore increasing the output of the engine and effectively creating more power.

_____________

#3.
Q) Where can I buy a FMIC setup?
A) 306's never came with a FMIC as standard, and because of this adding a FMIC is considered a custom job. There are companies that can supply kits such as DERV Doctor. However it is usually cheaper and more effective to put a kit together yourself.

_____________

#4.
Q) I have a 1.9 diesel turbo, so replacing my TMIC with a FMIC will just increase my cars performance with no additional work?
A) By adding a FMIC, it does not give you more power directly, but it enables you to cool the boosts charge more. This means you can use more boost to burn more fuel, which in return, gives more power. So whilst it gives you more potential it doesn't directly give more power. It will also sustain the power on hot days, without slowing down once warm.

#5.
Q) I have a 2.0 HDi, will adding a FMIC increase my cars performance with no additional work?
A) No. By adding a FMIC the potential of the car is highly improved however in order to increase the power of the car a remap must be done. There are a variety of tuning companies and individuals who can offer a remap for your car. MrWhippy (Dave) is highly regarded by myself and others across the forum who can offer a variety of maps at reasonable prices. It's worth bearing in mind that when a powerful map is uploaded after the FMIC is fitted the clutch is likely to slip and a performance clutch must be fitted. MrWhippy offers a limited torque map which is defiantely a more cash friendly approach to this problem.

#6.
Q) What Inter Cooler should I get?
A) There are two main types of intercoolers that people tend to use:

-Single Pass
[Image: photo026optimized-1.jpg]
(Chris's)

-Twin Pass.
[Image: DSC01689JPG-1.jpg]
(mongo's)

The arguements as to why you should get one or the other are endless. At the end of the day, twin pass are harder to find 2nd hand and are therefore costly to buy (around £80 - £130 brand new) where as single pass are avaliable from £5 upwards (2nd hand of course). Twin pass are usually tidyer as they sweep round one side of the radiator etc where as single pass must route around both (which usually requires cutting).

_____________

#7.
Q) So what bits do I need for my custom HDi FMIC setup?
A) First you may want to consider how much money you have to spend. If your budget is endless then a twin pass would be my choice. Again it can be argued which type is better. I myself have gone for twin pass and will therefore list all the parts I'm using.

- Boost Gauge, Boost Pipe (Comes with Gauge) & Bleed Screw to tap and thread into Inlet
- (2x10") Slim Line Fans (I never put these on in the end, don't bother in my opinion)
- 406 Inlet Manifold & New Gasket (An essential part of the build, try to get the round ended 2.25" one)
- 406 Turbo Pipe (A good fit, but could ideally do with a couple of inches cutting off the larger end if you want to keep air-con)
- Large Twin Pass Inter Cooler (with mounting kit) (From Intercooler King on eBay)
- (2x) 1 Meter 2" Aluminium Pipe (The whole setup uses about 1.2 Meters so get 2M to be safe)
- (5x) 2" Silicone Bends
- (1x) 2" Double Humped Silicone Straight
- 2.25" > 2" Silicone Reducer
- (2x) 3" > 2" Silicone Bends
- Mikalor Clamps
- Aluminium Mounting Strips (for securing top of intercooler)
- MrWhippy Stage 2 Remap

Here is a couple pictures:

Obviously there are subsitutes for every FMIC build and cheaper/expensive options are avaliable.

_____________

#8.
Q) So what are my options for remapping my HDi?
A) You can either go to a tuner who will upload the map for you or you can buy the gear needed to do it yourself. You need to buy a KWP2000+ which is used to read/write the ECU via the OBD2 port near the fusebox under the steering wheel. This is simple to do and takes a matter of minutes.

[Image: 925200835018213-1.jpg]


Here is an explanation on how to read/write:

KWP2000 instructions

VERY EASY TO USE:
- install the driverpackage to your notebook/pc
- connect the ecu-flasher to a free usb port
- point windows to the folder where you installed the driverpackage
- reboot

How to read data from a supported ecu:
- connect the hardware to your usb port and to the diagnostic port of the car
- start the communication software
- turn ignition on (not engine, just the ignition only)
- select the ecu you want to read/write from a list
- select additional options (if needed)
- click the read button to read out the original data (where supported)
- save the file to you HD, edit or forward it

How to write data to a supported ecu:
- connect the hardware to your usb port and to the diagnostic port of the car
- start the communication software
- turn ignition on (not engine, just the ignition only)
- select the ecu you want to read/write from a list
- select additional options (if needed)
- click the write button and select the file you want to write
- follow the instructions on screen
- switch off ignition and wait 10 seconds. done.

Q) How do I bead my pipes so they're less likely to blow silicone off?
A) Preventing your IC pipes from blowing off by home built pipe beader.

Q) If I'm fitting an uprated clutch, should I lighten my flywheel at the same time?
A) Look in This Thread. It's down to personal taste, the thread contains some strong opinions.

_____________

Q) Can I fit my boost gauge before and/or after the FMIC has been done?
A) It's pretty pointless fitting one to the standard manifold but the principle is the same regardless of what manifold (306/406) your tapping a feed from. Here is a guide created by Shaw: Clicky.

_____________

Q) I've fitted my boost gauge pipe feed but where can I run the pipe through into the car?
A) Theres a little gromit at the back of the bay that pops up at the top of the drivers footwell. I can't really discribe it so I've circled it in a picture:

Might be a retarded question, but it is 6:41am.

Do you lose your TMIC when you upgrade to FMIC?

Yeah you remove the TMIC and fit the FMIC

Im not overly sure on Hdi's but i know to the right of the brake servo the is a grommit which you can use, you'll have to get down low to see it, but with a torch and your chin on the slam panel you should be able to find it!

In the middle of front mounting my hdi and have a bit of bother fitting the inlet because of the egr and don't know what to do with the pipe below the new inlet

what pipe do you mean? ideally while you are at it you should blank off the egr with a plate. if you mean the pipe going to the turbo then obviously it will now go from the inlet to the cooler, and then to the turbo

oh and apparently moving the old pipe from inlet to turbo is a bitch, only some people seem to manage to get it out whole

When we took the old inlet of it was going into a pipe In below and with the new inlet and there's no where for the pipe to go, it's the big pipe in the pic ^

Pull the pipe out, it is possible to get it out in one piece, but unless you're planning on keeping it i'd cut it in half wherever you can and pull each end out separately.

Got the problem sorted the pipe wasn't on the bottom
Of the air box and there's a wire broke on the accelerator cable

Knowing how low your cars normally are, i'm still going to say that lower pipe is going to get totalled on the road. Confused Had you thought about routing it back down the side of the rad, or up through the slam panel (cut a notch for room)?
