Okay, I know GT40_Gearhead suggested the idea, and we're talking about cars in that one dude's Roush Mustang thread, so let's all take it here.
To start... uh.... I like the RB20DETT Engine (2.6 Liter, V6, Twin Turbo Engine, found in the R33 and R34 Nissan Skyline GT-R's, the Skyline 4-doors got the RB25DE, the N/A 2.5l V6). It's sexy. Kind of like the SR20DET (2.0l, v6 I think, single Turbo engine found in JDM Silvias and USDM Sentra SE-R's) or VQ20DE (2.0l, v6, N/A Engine that Nissan uses in 8 of their models including the 350z and G35, which is also known as the Skyline 350GT).
Yeah, I'm a Nissan geek.
