Best turbo for a stock VVT block that's getting forged in the future?
Hey guys,
New to the forum, but I've been lurking for a while. I've been a bit lucky recently and got handed an opportunity to get a rather large discount on a turbo kit (T25 flange)
Question is however, what turbo should I go for? I've had a few on my mind and I don't mind paying a bit of a premium if it saves my ass in the long run. I've currently got the following turbos shortlisted. 280whp is probably the most I'd ever want out of the turbo once I build my block, preferably 200 whp before I start modifying the internals.
BorgWarner EFR 6258/6758 - I personally opted for a 6258 initially, but the kit manufacturer said that the 6758 is a far better turbo. My worries with the 6758 is that it might blow up my block down the road. I like these for their supposed fast spooling. (Drove a NB 1.8 with a TD04 and that was lots of fun, but it did lack a bit of power)
Garrett GT2554R and Garrett GT2560R - Tried and true on MX5's, but I heard the 2560 doesn't spool as fast as a 6258 and the 2554R isn't quite up to the task of 280whp once I go built
Garrett GBC20-300 - Suggested as an alternative by the kit supplier, but journal bearing is off-putting. Worried about how these spool. Can't really find much about them online either
Pulsar G25-550 - Knockoff Garrett, not sure if I'd want this.
What are your thoughts? Anything I'm overseeing? The 6258 is the one I'm still leaning the most towards to as I'm afraid a 6758 will straight up murder my block even at tame settings. Pump gas here is 98 octane (93 US) - Magic corn juice (E85) doesn't exist here unfortunately posted by unitedpuggs
