Thread: intercooler budget build shortstack

well I also have to cover the coolant ports which involves buying the correct size tap for plugs (I already have a nice drill) and I live in an apartment whatever grinder I use will need to be battery operated so it will cost more and not to mention cleaning the shavings out and just cleaning the part in general. do you think I could use the drill and just put a grinder attachment on it? or would clearance be an issue also im still unsure of what im exactly grinding is there a writeup some where or could someone provide a picture with a circle or 2 I read bills LIM thread but he didn't have pictures for machining for an intercooler if I recall

okay cool thanks for the link just seen a 2006 Supercharged grand prix pop up at the junkyard maybe ill grab the LIM off that and just mod that one my self theyre only like 35 bucks there

people here have use a dremel with a little cut off wheel,,,many of em lol to open up the lim.

ive officially decided to my this build interesting after a dude on Facebook who i paid for lifters and spacers wasted 2 weeks of my time then said i dont want to do business with you pissed me off i found a set of cheap modded rails and a whole extra ssic kit ive decided to do a dual core ssic with phenolic plate build. it will involve a dual pass heat exchanger, vw rad, Bosch pump and Mercedes pump. its not so much a budget build anymore but still not a bad price for everything considering the amount of coolant that will be in the system. ive updated prices below.

things I have bought
-short stack core with long bolts and 1/4 in. spacer $225
-Mercedes m-class electric water pump with mount and pigtail $15
-1.25 in. hose and front PCV hose free
-coolant $30
-vw radiator $40
-all hoses and adapters/fittings with water wetter $35
-found some old catch can mounts in my toolbox use them for the radiator free
-coolant reservoir $5
-modded fuel rail $120
-valve cover and RTV and elbows $40
-junyard LIM to machine $30
-second ssic with bosch pump and dual pass $320
-brake clean $10

still need
lifters
LIM metal gasket
Fsic bolts

running total: $750 still need $150 worth of parts but i can sell my old LIM and ssic bolts to cover and may be able to get a deal on lifters or Fsic bolts

installed the core finally only installed one as there was no way in hell I would be able to close my hood with 2 short stacks and I already spent the whole weekend running into other problems so I was just fed up and did one I had to hammer the hood for just one to fit I do still plan to run a fmhe and vw radiator on the same system and a boosh pump along with the Mercedes pump just wondering from you guys if the Mercedes pump would help or hurt? I know its original purpose is an auxiliary pump so I feel it would be doing the same in this scenerio

both 3/4 just like the bosch pump but the pump itself is about half the size of the bosch pump

people are saying 0.9 amp draw? if that sounds right im not sure I need to learn more about electricity

almost finished over the weekend just have to wire up the pump and fill the system with coolant I ended up only doing the vw rad which seemed really nice as its a tube and fin design and has A TON of fins and bosch pump as I didn't have much room and best cutting tool I have is a hand saw and wire cutters lol but I mounted everything up pretty solid and have the coolant bottle in a nice spot plus I have probably over 10 feet in hose and only plan to drop from a 3.1 to 2.8 pulley anyway so I should be alright let me know what you guys think also I live in Michigan so it doesn't get crazy hot here haha our heat wave is like a regular day in the south

i run my ic pump off a 30 amp relay. why let it drain the battery on ya. ive also got mine running full time, keys on, its on. ive got a inline fuse off my battery to the relay so i can pull that fuse to kill the pump if need be.

yea I was going to use a relay as well that's why I didn't finish last night as I didn't know how to wire it up exactly with the relay and wanted to do it right. could I use a relay that I don't use from the fuse box? or are they not 30 amp? also I have a spare add a fuse lying around and just about every amp fuse that I would need would I need anything else?

i wired it up just like you would a fog light kit. thats where the relay came from, a fog light install kit. or you can just buy one.



i have a relay like this, i used a self tapping screw to mount it on the strut tower. GRAINGER APPROVED Automotive Relay, 12VDC, 40A '@' 12V, 30A '@' 12V, 5 Pins, SPDT, Pin Config':' B1, Application':' Change Ove - 5RLU7'|'5RLU7 - Grainger

they sell the relay with a pig tail or you can buy female ends and crimp em on the your own wires you cut to size. how i did mine.

thats what i did, no on/off switch, used the wiper fuse thats a key on only fuse with a add a fuse. this way the pump is always on when the key is to run.
