What does this have to do with the forced induction forum? It seems like you have a question regarding rims and tires.

 

oh well my original post had everything to do with FI. guess we kinda drifted there sorry

 

You didn't ask a forced induction related question though, hence why I think you might get more responses in a different forum (and with a better titled thread).

 

okie doke. well to continue on forced induction topics:

does anyone know the pros and cons between the FP BIGt28 and the one from rrms kit...or are they the same? right now i have the t25 from rrm but im looking to go bigger. like forged internals bigger. so im trying to learn as much as i can.

correct me if im wrong but i can change the internals of my t-25 so that its a BIGt28? i like the idea of a quick spool combined with big power...but then again i am FWD

thoughts anyone?

 

Unless you want big power (ie. tire torching power), the T-25 should suffice.

 

(tire sublimating power)

 

Well what kind of power is that, 150 whp, 200 whp, 250 whp, 300 whp, etc.? What is the application? How much are you willing to spend?

 

swapping from a t25 to a t28 wouldnt be worth it unless you are actually making real boost.. ie above 1bar.

 

^This man speaks the truth.

 

well my goal is 1.38 bar. saving for internals right now and i know this is going to take time. i love straights and i love twisties so it would be somewhere between a drag and autox ride. i dont want 2 much lag down low but i dont wanna run outta juice before rpms. Im not worried about money..just trying to learn right now about the different turbos so i can set my sights on it for the future. i have alot of work to do right now to prepare the car for that kind of boost.

tranny: stg2 clutch, tob, flywheel, lsd
susp: coilovers, front sway bushings, strut bars, tiebar
engine: pistons, rods, im port, throttlebody, portnpolish head, camshaft, lw pulley, new timing belt(soon!), motor mounts, fuel rail.

my to do list.

 

Well those are very different things (drag and autocross). 20 PSI is a big goal, you'll need a decompression gasket to run that.

 

go t-28 or 16g... the t-25 is too small imo...

 

yea t-25 is def 2 small but im still trying to figure out difference between t-28 and bigt28/FPbig28

 

I would assume it's either compressor wheel size or the big T-28 is just a ported version of the T-28 but I'm not sure.

 

Yes, some lofty goals I see here...but it's doable! And no you don't "need" a decompression HG, but lowering the compression does tend to make the tuning that much safer for longevity sake.
