I've currently got a 55plate blobeye wrx & I know my currently turbo is only capable of achieving 290-300bhp at a push.

So my question is I'm wanting to upgrade it to one that is capable of producing over 300 but nothing too big as I know my gearbox can only handle so much torque before destruction & I'm not wanting to go past this mark. So which turbo is the best to go for?

Cheers
Scott

I did what your wanting to do and in the end sent my original td04 off to turbo dynamics and got a 16g billet wheel fitted which gives out about 310 to 320 bhp with similar torque.
I first wasted my money on an old vf35 that was smoking on idle.
I'm sure you can get a decent vf35 but it is luck of the draw.
My rebuilt turbo td04 cost 550 but you get a years warranty and the best of spool and power in a small turbo.also it really is like having a new turbo that should really last the life of the car.
Luckily I got my money back for vf35 but paid for it to be mapped first so lost that money.

sc32 will do 300 with some seriously epic spool.

need to have the right supporting mods to make the most of what ever turbo you have

I'm in a similar situation pal, my wrx is currently at 270bhp, I have went for the vf35 and sti pink injectors, parts are sitting there ready for February to be fitted then mapped, hoping for around 320bhp 👍

So what is a safe when taking that I do not want to start upgrading the gearbox, 330-340?

Also would a TD05 from an STI take me to the safe limit?

Last question what supporting mods will I need to get me there?

LolIve read anything over 350 then your on borrowed time, a td05 will get what your after but I think the td05 might need converted to front entry to fit 55 wrx. Supporting mods I think are full exhaust, k&n pannel filter, 550 sti injectors, walbro fuel pump, I also have a sti tmic and 3 port boost solenoid but not sure if necessary. Then obviously the turbo. Ive also purchased a sti decat uppipe to go on with the new turbo.

My previous uk300 was running 336bhp for over 4years without any gearbox/engine issues. Vf28,pinks,sti tmic,walbro pump,panel filter,sti inlet and racedynamix map. Would pull away from my mates 350ish blob sti.
