I haven't poster in over a year, so. . . Ok, Everyone knows that in order to do any b series swap CORRECTLY into an eg/ek chassis, you need a radiator out of the 99-00 civic Si or the Del-sol Vtec. BUT WHERE DO WE GET THESE THINGS CHEAP???????? SOMEONE HELP!!!! The problem is that these radiators are not readily available at a decent price, so what are we to do? The reason this needs to be done is all about a tiny little 1/8th of an inch, on be series engines the radiator hoses are 1and 1/4 inch, but on the d-series, they are 1 1/8h inch, leaving a gap that either is leaky or unstable. Some people have managed to stretch the d -series hoses over the water outlets on the engine, but after a few months the hoses blow because all of the fibers inside were broken during the stretching. I have seen others clamp the hell out of the b-series hoses onto the d-series radiator, this is good until they either leak or blow off. If you know someone who works at honda you can usually get the radiator you need for about 200 bucks, not bad for an OEM Genuine part, but sometimes this can be above budget for some people. So you look to aftermarket companies (auto zone, pep boys, advance, etc.), 100 bucks, lifetime warranty, AWESOME (keep reading). . . How many of you have tried this?? You always get the wrong radiator!! WTF, for some reason the aftermarket companies seem to think that the dx/ex/si radiators are all the same, 92-00, so you are right back where you started with the wrong size inlet and outlet holes on the radiator (too small) Another suggestion is to use the radiator out of an integra, which by all means is a great idea, but requires a little bit of fabricating to mount it. Provides greater cooling and looks better under the hood, but if you don't have this radiator available to you, then you still have to spend almost 200 for the aftermarket version, and if you aren't handy with a torch, grinder, cheisel, welder, etc. then you have to pay someone for that too. I have done about 10 full out b series swaps into eg civics, and when it all boils down, the radiator is the last thing that gets put in and usually the biggest pain in the ass. Someone needs to either please post and stick where to get a good aftermarket (oem style) radiator CHEAP for the 99-00 si or the del-sol vtec so that these swaps are made jsut a little bit easier. or a place to get custom hoses that go from 1,1/4 to 1,1/8. And if you read this far and just don't give a crap. . . Thanks for reading anyway!
