Intercooler: Blitz or HKS Type-S???

[the_invisible]

I am aiming to get about 300hp at most, so which intercooler is good? HKS or Blitz?

I like the HKS with the bigger core, but the Blitz one has less pressure drop, which is good for stock boost.

Any idea? For the size, HKS is pretty good value for its price.

[BuudWeizErr]

I prefer the Blitz. I haven't compared the Blitz to the HKS directly, but I've heard the Blitz piping is a little nicer/better. Again, I haven't compared them directly. I'm sure they are both better than the GReddy kit though. No directions or templates or extra supplies = bad.

all the greddy intercoolers i have put on had directions and supplies. they even had the spot for the bov in the factory location. the blitx kits don't have this at all. you have to modify a pipe to use a bov. the cores are almost identical though. also, i like the greddy brackets better. but i mean, they are both nice intercoolers.shauns14 sr20det special...$1800

your selling an s14 sr20det for 1800??

I have not done anything in lew of installing an SR intercooler but I have been researching pretty hard. What pampadorisaid is true, but there is more. The Greddy has a mounting spot for a GREDDY BOV, which have been known to wear out over time-this applies to the type S. This mounting position is on the cold pipe leaving the core, some people want it there and some want it on the hot pipe. Any other BOV will require not only custom mounting but also welding the provided flange/hole shut- not so cool. As far as I know the onlu intercooler kit that provides a hot pipe is HPI. So it does not really matter if you want the BOV on the hotpipe like most people. Blitz, however does offer a FULL hotpipe replacement BOV kit, with the whole shebang ready to go with the intercooler, so does HKS (S13 only so far). A Greddy VSPL and Type S BOV will be cheap, but the BOV is located by your battery and you have to retain your stock hotpipe unless you replace it, which makes this route not so cheap anymore. I personally will probably get a Blitz intercooler and BOV setup, although I love the look and sound of the HKS BOV. the HKS full BOV/hotpipe kit is polished and damn sexy too. As far as instructions and brackets, I dunno jack.Here's where: http://www.phase2motortrend.com

Umm why not install a GReddy Vspl, with a Type S installed in the factory location. For maximum effiecieny? Like my setup...

[hokiruu]

so what did you do with the VSPL mounting flange?

this isn't correct. the s13 greddy kit has the bov "stub" on the pipe just before the intercooler. the pipe that the hot pipe connects to. this is the s13 stock location although not the s14 which has it on the passenger side under the battery. the greddy intercooler doesn't have a greddy only bov attachment. its just a 1.5 inch pipe welded to the intercooler pipe to ease your bov installation of whatever bov you choose. there is no flange, just a 1.5 inch pip to weld on a flange (jb weld held mine for 3 years.)

also the greddy rspl pipes are very very nicely polished. the vspl isn't polished but is shinier then the blitz pipes.

your selling an s14 sr20det for 1800??

yes, very clean but no ecu or harness.shaun

[pampadori]

so what did you do with the VSPL mounting flange?

she didn't do anything with it. there isn't a flange, just a 1.5 inch pipe pertruding out. she fitted her bov here via welding or somehow.shaun

Pampadori, thanks for clearing that up. now I have to clear something up. After talking to the guy I know who had the Greddy FMIC I had in mind, it turns out he had a Skyline RSPL application intercooler on his s15 motor in a s14 chassis, so I am sorry if I posted incorrect info but I didn't know his crazy setup. Apples and oranges... Another thing to consider in chosing an intercooler is pressure drop with size. Some people seem to want a huge intercooler because it is rated up to higher top HP and gives you room to "grow." However these may not be ideal for some because unless you are running a large turbo/ high boost you may not be able to fill it completely, resulting in a loss in pressure/increase in lag. Kinda like the guy I just mentioned...

[pampadori]

Intercoolers are not something that you can rate in terms of power. the vspl is said to be good to 400hp. this is crap. you can get 600hp out of it with good tuning. the pressure drop issue is also wierd. pressure drop chills the air temp and reduses heat. that is one way an intercooler works. making air cooler will cause it to be a smaller volume of air.<----thats pressure drop. most intercoolers are pretty good these days. i had a friend that had a stroked sr in japan and laughed at my intercooler for being so big. said it wasn't needed for my power. rambling *off*shaun

[hokiruu]

That's interesting Pampadori. I guess that's what I have been wondering about and oping someone would address. But how will you really know? Trial and error, lots of tuning I guess?

[pampadori]

the hardcore just run it until something breaks. then they findwhat broke and put in a stronger one. i would just pay attention to knock and play with plug gaps and a/f ratio.after taking my motor apart, after 3 hard years of driving, the bottom end looked ok. but for the price the greddy and blitz kits aren't that bad of a deal. shaun

[hokiruu]

I don't understand knock completely and how spark plug gap is related to it. Can you please explain to a poor inbecile like me?

[GodzillaFan]

spark plug gap isnt related to knock. ignition timing, compression ratio (static and dynamic, boost pressure falls in this category)intake air temp, combustion temerature (richer=cooler, to an extent) are some factors

i suppose its possible that a smaller spark plug gap could increase knock, if your timing is already on the bleeding edge. since less voltage would be needed to create a spark, resulting in a earlier spark. but thats unlikly, and you'd just retard the timing a °

[Silviagirl79]

so what did you do with the VSPL mounting flange?

I used a GReddy flange, attached it to the BOV, and welded it to the factory mounting location.

[Silviagirl79]

yes, very clean but no ecu or harness.shaun

I would be interested in the turbo.

I don't mean to be an a**hole but could you please either email, IM or move this negotiation to another forum? That way me and everyone else are not subscribed to your every transaction regarding this motor, turbo, whatever, its in the the wrong forum.
