I want to get some input on this.
My next stage of modifications is an intercooler.
I have been having been toying with a bunch of ideas on which route I should go. Top mount, water to air, front mount. Everyone can argue which is better and why.
At this point I am ruling out running a W2A system for a few reasons.
1) Efficiency (which is debatable I know)
2) Simplicity (I like simple systems not running pumps and lines and a separate radiator
3) Under the hood room
4) unlikelihood of core failure putting water into my engine.
I don't have the room under the bonnet like the 80 series crowd unfortunately.
I am between running a top mount or a front mount.
Top Mount:
I am between running a few different ideas.
First would be buying the HPD top mount.
http://hpdiesel.com.au/toyota-landc...ruiser-top-mount-75-79-series-intercooler-kit
It has been confirmed talking to a few people that the kit can be bought from ebay at better than half the cost. Direct bolt up with no issues. One of my sources have mentioned that they saw a good EGT drop fitting this cooler.
http://www.ebay.ca/itm/TOYOTA-Land-...Parts_Accessories&hash=item4d0c8dbd43&vxp=mtr
For everyone looking at the kit the seller is very helpful at answering questions. The fan pulls 1500cfm and can be supplied with 12 or 24v fans. They also have 2 bonnet scoop options. He can also subtract the scoop and give a discount if you want to run a different one.
The the other top mount idea that I am having a debate with is just running a simple $100 ebay core, spal fan, designing a custom plenum and trying to make it all fit. There isn't much room under the hood if I mess up ordering a intercooler too large, fitting a fan underneath and trying to adapt that to a plenum while getting it to fit centralized under a bonnet scoop.
Outlet of the turbo compressor is 2" and the inlet of the intercooler is 2". Can this be a restriction, is it worth it for me to jump to 3" as soon as possible or even 2.5"?
Pros:
1) Bolt up
2) Cost ($650 to my door for the intercooler)
Cons:
1) finding a hood scoop I like (which is posing to be an issue)
2) cutting a hole in my nice hood!
3) core is small (insufficient cooling?)
3) if I don't go the custom route I can't do an enlarged plenum
4) Intercooler fan my suck and be no real benefit because it does not have the pulling power
5) fitting a better fan may not have room
Reasons why I am considering the enlarged plenum:
1) better throttle response
2) lowered EGTs
3) lowerly likelihood of cylinder leaning out air in 1 & 6
Front Mount
I have been told time and time again (mainly be Graeme) that the best thing to do is to fit the largest front mount I can humanly fit.
I have been looking into ways I can fit one. My only option at this point is to do a slight modification with the front valence and the grill.
HPD has a kit ($1300 + shipping) which is too steep for my budget. Not to mention I think their piping system is below par reading other people review (too many silicone bends). I would rather get piping welded and do as little silicone as possible.

HPD's kit for reference
Pros:
1) I figure this would be the cheapest route and most simplistic
2) I could fit do a custom plenum with this setup
3) Engine fan is the ultimate puller fan
My only concerns with going front mount:
1) Turbo Lag due to increase piping
2) Airflow from obstructions
3) Susceptible to getting clogged with mud
Airflow is my concern because I am running an ARB bumper on my truck. I am also switching to an 8274 Warn and I run two big fog lights. Looking at Huslty's build there will be enough clearance for the intercooler behind the winch with an ARB bar.
Think this will be an issue for getting sufficient air to the intercooler?
Lastly, Intercooler piping size.
I have heard go as big as I can fit 3" (more air the better) while I have heard just stick to 2.5" piping.
I have a whole bunch of 3" stainless that could be used
Thoughts?
