ok guys i need your advice. i want to fit a fmic to both mine and my sons r33 gtst skylines here is the problem i am faced with. what do i buy do i get a bar and plate or a tube and fin intercooler is there any advantages or disadvantages with either cooler im so confused the more i search the more confused i become my head is starting to hurt :rofl: also outlet size is 3 inch the way to go or 2.5 inch both cars only have exaust 3 inch cat back. pod filter. what type of performance gain can i expect going fmic over the stock one?

there are also many different types of bar and plate / tube and fin. The way the tanks are made and set up make a massive diffrence on how the air will flow through the core. (wish i could find the site i got this from) The 2 main types are not better or worse then each other both are used for differant applictions. Just make sure you get one that is a known brand not the chinese nock offs, even though some of them are actualy good.

What you want to look at it the point at which the tanks and pipes will flow through the core, eg if both tanks and pipes are in the same entry/discharge point you are not utilizing the hole core, the pipes need to be at different points or have some sort of displacement to spread the flow but not impede it. Hope this is some help

All of that was from a full report on intercoolers

Ok the general rule is that bar and plate cool better but are more restrictive. Tube and fin flow better but don't cool quite as well.

Most people put the tube and fin on their skylines because they don't need any extra restrictions, especially with a stock turbo like you obviously have.

I have a tube and fin. Enough said. :P:D:D

Tube and fin was also supposed to have better flow-through to your radiator. I'm sure i read that somewhere.

And yes, what ^he said - better flow through the intercooler core, but less cooling ability compared to bar & plate.

I did a lot of reading on this a while back.

And i also got tube & fin :P

make sure you get one with a good designed end tanks. Its all about the flow through the tank as mentioned. See the std GTR intercoolers for the design im talking about.

i hate the cores that have the inlet / outlet down the bottom.

If you only want up to 300rwkw the GTR ones are more than capable, and are tube and fin = good flowing of air through to radiator still.

Ive got a hybrid of bar and plate / tube and fin. Just thought id add that to confuse you even more. :P

In terms of performance on the street I don't think there is any real difference between bar & plate VS tube & fin. Just make sure you get a decent brand. I'm another one with a tube & fin 'cooler.

"When I grow up, I'm going to Bovine University!"

looks like people are heading more towards the tube and fin design intercoolers.

As said above though its good to have the better designed end tanks thats where im not sure which way to go as the bar & plate cooler im looking at has the better designed end tanks and the tube & fin cooler i am also looking at has the normal end tanks. Seems most people are still going for the tube and fin design with the normal style end tanks is this correct?

cheers allan

    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
