TB/Plenum

Hey, I need your help guys. I've used the search and read up on throttle bodies and it seems a lightly modded engine would only need like 65mm TB. Well, locally, a guy is selling a 75mm and a C&L Upper Plenum and I was wondering if I should act on it. I only want to offer him like 250-275 dollars based on that it's 330 on Brenspeed. I'd just really appreciate the help because I'm still learning about engines and I'm not sure if this is something I want to do, I just don't want to lose out on a good deal.

Thanks alot.

and this would be my first engine mod.

Cool, thank you. Is there anything else I'll need for this or is it just a bolt on?

The guy is also offering some Tein lowering springs and shocks which I was initially interested in but I don't think I want such an aggressive drop for a DD.

Thanks for your help man! Yeah, my ultimate goal is to go blown or a good NA build up.

Yeah, I was kind of iffy on the tein stuff. I've only seen those springs on ebay for cheap.
