Looking at changing the turbo hopfully in the next few months on my v5 type r along with some other mods such as fmic, 550 injectors, 3 port bs, Aiming for 360- 370 bhp don't really wanna push the old girl harder as I believe that's about ur limit on stock internals.

My question is what is the best turbo at an affordable price, now I no the sc36 /38 is the best out there but the chances of one poping up are proper rare and at a grand new just outta my budget so I'm thinking either the td05 18g or 20g.
If I buy a 18g I think I will be using it to its full capacity which I believe to be a good thing and the 20g been a 400+ turbo will not be used to its full potential, so do I have this right and have I answered my own question or have I got it compleatly wrong.

Thanks

I think you will be lucky to get 400+ out of a 20g. Mine is out at 380bhp which is a common figure for one of these on vpower. I would go for an 18g if your happy to achieve 360-370

I'm in the same boat my wagon is running just under 320bhp and now want more and considering a 20g a andy's forest one, sunnyjones whats the spec of yours mate sounds interesting

I thought the 18g was good for that sort of figure (380bhp top end ) so If thats the case what are the performance differences between the 18 & 20g... I mean do they perform the same...
I read that the 20g is also more suited to a 2.5 as apose to a 2 litre...

Do I have any other options apart from the 18g obviously apart from that mentioned

I would reconmend 20g all day they are awesome i made 380bhp on a standard uk wrx the mapper said if he put it on dyno to do final tune it would be very very close to 400

Yep the 20g is a 400 bhp turbo but I don't have forged internals so that would be a risk on my classic !

This is why I'm wondering if I should use a 18g to it full potential over a 20g

The 18 will spool better than the 20g and on a well set up car with the right mods . do 370/380. With meth mine does 401

My Classic with 18G is making 370@1.4 bar v-power...but i need to be nice to the box 1st,2nd+3rd. Driving wise spool is Low, fast and torque-y! Real 18G's are not cheap though-where are you looking?
think for the future...
If you have 400.. you want 500 a week later...and so on! are you stopping at 360/370?

Tbh Ive just been keeping my eye open as much as I can either on here and 22b and eBay if somthing was to pop up o and pistonheads but nothing so far not sure where else to look. Not intrested in a cheap copy though ..

I agree with what ur saying 400 then 500 but I would need to be able to afford a rebuild first so I will be happy at 370bhp for A while and then I will take it from there.

Thanks bud ... I had a feeling the 18g would be suited better for what i Needed but I see a few people running 20g on efectivly the same setup I will have and just had to ask ..

Another vote for 18g, midrange is awesome,running method on mine so should be close to 400, feels like it anyway

Thanks stedee ... I just thought using a turbo to its full potential would be better than using 3 quarters ie the 20g I'm not gona be going over the 370bhp unless I can afford a full rebuild and a 6 speed and that will take some saving
Lol

ah right if your not going above 370ish i would 100% go for the 18g. dont even think, just buy it lol...

im running a 20g as i said on my first post, on my bug wrx 2.0. i cant compare anything as i havnt got the same mods as you but what a fun turbo to drive.
