What Turbo ?
 

Hi i cant seem to find the information on what turbo came on the V2 STI 555 is it a TD04 or a TD 05 16g ??

A TD05 16g i recon .

TD05 90 degree entry.

All JDM classics except the JDM WRX wagon came with TD05 90 degree entry.

All classic UK car's had TD05 90 degree, despite what some advertisers say about TD05 equipped UK Wagons being upgrades.
I think some people have even fitted/bought TD05 for UK wagons only to find they were the same.

i thought my rb5 had a td04?

Sorry, should of said Pre97 Classics.
Post 97 UK/EU had TD04 straight entry
Post 97 WRX/STi had VF22, 23, 24, 28 or 29 depending on model and age.

so td05 90 degree as in top entry ? will still be 16g ?

16G was a name applied when they started converting them to front entry to distinguish between 16G, 18G, 20G compressor wheels/housings.

But a standard Pre96 turbo is essentially a 16G but I don't believe it was ever officially designated as such.

Strong little turbo to! Ported will make 340/50 hp, and considering how old they are they still going , housing don't crack as easy compared to the vf range
