Has any one here got an intercooled 75 series? i'm looking at replacing my W2A intercooler with a FMIC, but the plumbing is going to be a bloody nightmare methinks. I don't have an air conditioning condenser so it's easy enough to fit it behind the grille, but the plumbing to and from has me stumped how i'll do it.

Any links to pics?

Why are you changing from WTA?

There is a bloke clint ? with a FZJ79 that has a front mount setup, I dont have a HZJ75, a BJ74, which looks like there is plenty of room for piping etc, just lots of bends. Clock the compressor hosing and run the hot side beside/under the ari box, cold side beside the rad then up the side of the motor, look what how a HDJ79 after market kit works, would be similar.

As others, why moving away from the WTA ? I have a W2A setup and it work pretty well, knocking off 70c at 25psi, A2A would be a PITA to fit up.

Thanks guys

I'm not all that sure that the W2A is all that efficient. It's a PWR barrell with a 16" radiator at the back of the car. If you touch the radiator are a good hard run it's warm, but certainly not hot. I really havn't got any way of telling just how effective it is.

Plus i'd really like to simplify the whole shebang. Having water hoses running the length of the car, plus a pump, plus a thermo fan and radiator at the back, it's all a lot more complex than running some air plumbing to the front.

Also, the W2A is great for low airflow/high load applications like driving through sand or competition work, but the car is now getting used for towing and general pottering about town. So in my mind, the FMIC is going to be more efficient at higher speed/airflow which is where the turbo is going to be making most of it's boost, as opposed to the W2A which isn't anywhere near as efficient at high speeds and at low speeds i don't make any real boost anyway.

Finally, the cooling system in my truck has always been marginal at dealing with the added heat from the turbo, so if i really do have to have a rear radiator (which gets in the way when loading up the truck with timber or just using the tray) i'd rather it be as a secondary water cooler.

Does anybody think that a fan forced TMIC is really that much less efficient than a FMIC? with a bonnet scoop and a puller fan under it i would it really suffer from heat soak?

how much you want for the barrl cooler setup? top mount air to air i feel are better then front mount.(unless they are a purpose kit for that vechicle)

Is exhaust all options for a FMIC before settling on top mount.

Hulsty, are you referring to clint79 ?

On a side note, what's is the air temp BEFORE the i/c at 25 psi and how much pressure do you lose thru it....

I lost about 2psi through the W2A from pwr. but i suspect it's not just pressure losses it's also the air recondensing and becoming denser due to a lower temperature.

well i've got the room behind the grille. But the plumbing is likely to be a TOTAL ball ache. When you come up for the weekend you'll see how routing will be a PITA.

What are the temps before and after the I/C at 25lbs boost

Next question? I have no idea. I don't even have the means to check

Food for thought.

Not sure how similar 75 & 79series are?

I don't like the way the intake pipe snakes back to the inlet manifold.
