is it possible to use the stock radiator cap on the radiator?

 

yes, everything fits except the bleeding plug

 

What would be better?? The Koyo or Fluidyne?? I want the one thats going to cool the best.

Also has anyone ever bought from www.sportcarmotion.com ????
They are selling the 86-88 Koyo radiators for $345.

Thanks.

The stock cap fits on mine, but I have trouble getting it off sometimes. Its really tight in there. I guess thats a good thing.

I know the Koyo is thicker than the Fluidyne, and it also has 2 chambers, which is why I went with it over the Fluidyne. Its also cheaper

 

Does 2 chambers mean better cooling????? Wouldn't it be taking more time to cool if theres 2 chambers???

the Koyo is so much better. it's thicker and it has 2 chambers. not to mention it's alot cheaper! but you'll need an electric fan since its alot thicker.

 

Koyo all the way.

 

I've ordered from Loi several times (sportcarmotion.com) He's great communciation and have had the tracking number for my product within 2 hours of sending payment. He got my GReddy stuff really quick to

i thought it was a stock drop in... therefore it can use the fan shroud and stock fan too

 

So the Koyo is a direct fit?? You don't need to relocated the battery??????

Also does the koyo need the factory grommets from the old radiator??? If so, where can you order new ones from. Thanks.

Yes, the Koyo is a direct fit for 89-91s. (or so I've been told).. I had to redrill two of the bolt holes to make it fit an 88.

Yes, you reuse both brackets from the old radiator, 2 10mm bolts hold the brackets to the side of the old radiator.

Good radiator, not as much cooling as my custom Griffin, but I don't have to move the battery with the Koyo (which answers your first question )

Cool, I was going to ask about that too, my stock drips from the middle somewhere very slowy and only when car is off?
