just got my car fitted with new injectors turbo and simtec 3 port boost solenoid its version 4 uk but full sti engine ie crank pistons etc. and i put a td05 20g on and its to laggy so will be selling it for a decent price but what turbo can i get that will be ok and n ot as laggy im looking at over 320bhp tho any ideas thanks again people

 

TD05 18G

 

Or a Billet SC36 if your pockets are about to burst

 

vf28 cant go wrong for the money

 

I suppose cheapest option would be a second hand vf35, good for 340 bhp and spools very good. They come up from time to time in the for sale section, so keep your eyes peeled.

 

+1 for the above and 1/4 of the price of a SC36 and with supporting mods will make 320 bhp comfortably,and also very quick spool up compared to othe IHI vf turbos.

 

so whats better vf28 or 34 will the 28 be ok for 350 bhp or not

 

28 won't make 350 on an accurate dyno. Mine made 342 at Zen but usually you'll see between 320 and 340.
I run a 20G and when we compared the graphs it spooled quicker than my VF28. This may well be due to the fitting of GT spec manifold and up pipe.

 

What do you mean by "over 320 BHP" .......325BHP ?? Cheap as chips TD05 16G will do that all day long

I run an 18G which runs 400 BHP with meth injection and 350 BHP without

whats 18g like mate lag or not im swayed with vf 28 or 34 tbo

 

VF34 should be less laggy being a roller turbo.......flows a little less air then the 18G so top end will be less.

tbo im looking at 2nd 3rd 4th gear really thats what power i want that 20g is soooo laggy bad decision i think lol
