Besides the spring rates, what do you think makes the GP Sports GR4's or KTS's better than Tein Flex's? Do you mean in the fit and finish or in the actual functionality of the units? (just curious)

 

spring rates have nothing o do wih the qualiy of the product. but you can see the qualiy differance by looking at the welds and then on a shock dyno they do quite well also.

he flex are nice dont get me wrong i just dontlike the dampning on em. but if you can get em for $1000 go for it

 

and those for us poor highschool students the spring/shock combo works just fine... haha i just had to throw it in there

 

I know that, I just wanted you to compare the coilovers without considering the spring rates. That's why I went on to ask you about the quality.

 

I know exactly where you're coming from man. It don't get much better in college unfortunately.

Must not be that bad for you if your doing at DET swap though, lol. Good luck, that's a big investment. I'd do a KA-t instead (T3/T4+iron block=reliable fun ) but to each his own.

You swappin yourself or having it done at a shop?

 

bah dont even get me started on swaps cause its a well known fact that the CA/RB series are best

 

Thank you Catharsis, your opinion will be noted. You seem to have one for everything

 

And I would't call that a well known fact. Maybe a well supported opinion.

 

I love the RB's, but I think it's best to leave them in Skylines. As for the CA's, they are great if you can source the parts when something breaks and can live with a somewhat peaky powerband. KA-t works for me (or will when I get the $$$!!!).

 

CA18det= 4cyl rb26

 

Yeah, now that is a well-known fact. What are you trying to say?

 

Those motors are great and all, but the US Spec 240 already has a boost-friendly iron block motor to work with, the KA24DE or KA24E. Just needs a little work (lower compression for DE, balanced bottom end for both) and a turbo and they can be quite potent.

 

If I had the money, I would have an RB series motor, but it wouldn't be in an S-Chassis; it would be in a Skyline, where it belongs.

 

With that said though, I think if it came down between the SR20DET and the CA18DET, I would choose the CA.

Iron Block > Aluminum Block

 

You know its late when the last four post are all you withing minutes of eachother
