Iam just about to buy a new turbo for my wrx blob eye which do people prefer between td05 18g and sc36 and Wots the difference?

 

They are both similar sized turbos, but i would go with the SC36 Billet as it would probably spool quicker as it is a billet. The SC36 would probably make a bit more power. They are both quite capable of shredding your 5 speed if your not easy with it.

 

thats if price is no object

actually i do believe there is an 18g billet now, i think andy f does them

 

yup, if you've got a budget to keep to, then 18G it is.

 

Heard about them, not too sure on the details though.

 

same here but i did hear from andy himself a while back they are good for 400, but that was a while back, i think they are a grand

 

Wot bhp would best to keep it reliable and r both them turbo's over kill for wot Iam after?

 

If his 18g's are really producing 400, then that's wicked. But too much for the op's wrx engine and gearbox imho.

 

350 bhp is normally the safe limit. If i were you i would go for a second hand vf35 from a newage uk STI. around £300. It is a 340 bhp turbo. You would need some supporting mods to reach those levels though. here is a rough list:

Intercooler: newage sti or front mount.
decat up pipe: newage sti
turbo-back exhaust: 2.5 inch
Injectors:Newage sti "pinks"
Fuel pump: walbro or HRC.
3 port boost solenoid: not necessary, but every little helps.

And then a remap.

 

Yea I've got all the above mods ready to go on just deciding which turbo, hard choice as people all say different things

 

I'd go for the smallest turbo to make the power you need as theres no point in having unnecessary lag. Ive driven an STI with a vf35 and i was quite impressed and would recommend one.

As for reliability theres never a definative figure as it all depends on how you drive, how its been looked after and what mods you've fitted, things like an uprated oil pump, sump baffle, FPR, decent oil and sticking to the correct petrol will all help the engine. Not changing gear too fast and launching too hard will help the gearbox obviously.

If i had a WRX i wouldn't go above 320bhp and 310lb ft, even at that i wouldn't thrash it.

If insurance ain't an issue then you'd be better off with an STI.

 

Would I see 320bhp 310lb ft, with a td05 16g?

 

yes, but you need one that has been front entry converted.

 

One of harvey's Td05 18g it is then

 

Dear god
