turbo shoping

[cwspellowe]

I know there is a waste gate model but iv read alot where the VNT setup with the GT20 was used, to reduce the lag... And £300 isn't bad for effectively a brand new turbo with upgrades its cheap. But you can always run second hand, reliability will always be a concern though as you don't know its past. At the end of the day he needs to specify what power he's after and where he wants it before people start telling him a definitive turbo to buy. No point fitting a GT20 if your after Sub 150 BHP.

Totally disagree. The newer GT turbos spool so quickly they make a massive difference to driveability. It's not all about headline bhp, the GT20xxS's spool so damned quick that the lag isn't really an issue, yes a VNT has instant boost but the wastegated ones are not to be looked upon as the same as older T25's and TD04's. I'm hitting full boost just over 2krpm, WAY quicker than the T2 I had before.

The GT2056S I use could theoretically run up to 190bhp all day long if the rest of the engine holds together. I'm still on a 9mm pump though (yeah yeah, XUD) and while it's not much more powerful than the T2, the chronic spool times compared to factory turbos makes it all worth it.

Oh and FYI a GT2056S can be picked up for sub-£150 if you hunt hard enough, a GT2052S possibly even cheaper. Completely transforms the way the car drives. Plus it'll produce less heat and will be miles more efficient than a factory blower. Might be overkill on a standard, unmapped car but totally worth it if you want to run stage 1+
