Alright, I've looked and looked but I couldn't find much info on the differences of these two intercoolers. I know the fins inside the intercooler are different, but what are the advantages/disadvantages of each? Does it affect spool-up? I know there's a thread around here somewhere but can't find it. I link would be great, but personal experience with either one would also be awesome. Thanks in advance,
Brian

 

V-spec is for the stock turbo and the R-spec is for the GReddy turbo kit. Same core I believe.

 

hmmmm, thanks for the quick response, if i go with their turbo kit then i guess i'll go rspec

 

Ya you can check it out on www.greddy.com

 

they don't really offer much info on the subject.

 

yeah, good question. Greddy's site doenst have any info on this at all. Contruction wise, whats the difference? Is one bar/plate and one tube/fin or something???

 

the RSPEC core is designed for boost 15psi and above with the greddy kit. VSPEC is better for stock turbo cars and has bolt in piping

 

So basically if i wanted to just use the core, a Gt35/40 turbo at 15psi and make my own special piping, i should get the R spec because it flows better? Just want to be clear on this one. Thanks

 

yup the rspec is gonna be better for that application

 

R-Spec core is a more efficient core in terms of heat transfer.&nbsp The V-Spec core is a better flowing core, but it doesn't transfer heat as efficiently as the R-Spec core.&nbsp This implies there is more pressure drop in the R-Spec core.
