Morning all quick question ..currently i have full decat with TD05/20 turbo and uprated fuel pump remap fettle with mark from thwaites im running a lovely 330.8 which although is down from the 367 she was supposed to have when i got her back is very smooth and no slouch but if i wanted to get close to 400 with good torque which turbo would you all suggest or should this be achievable with my current turbo..
thankyou

 

I'm no expert but have recently been researching which turbo to get myself... as far as I am aware a 20G should be sufficient for 400? Maybe do some other bits like headers, injectors & FMIC instead?

 

cheers for that i like the current turbo because of the early spool up and lack of lag but didnt want to push it to its max and increase its chance of failing have thought about front mount i must admit

 

Wow I'm surprised you have early spool up? I have always been told the 20G's are quite laggy?
The FMIC vs TMIC debate is always ongoing and some will say you need one some will say you dont... I personally don't claimt o know the science behind it all. I THINK 20G's are good for 420bhp so I dont think you would be maxing it out

 

Are you 100% sure you have a 20g as early spool and 330bhp sounds very 16g to me!!

J got a td06 20g Im gonna be putting up for sale next few days it's dated to 450

 

Td05 20 is not 400?

 

Will double check my paperwork later ..sounds like i need to get her back on dyno and look what she can safely go to on current set up

 

Hi Kev its a Billet 18g on there from APi which I believe is a Scooby clinic sc38. I looked into it and best way would be headers and bigger injectors or if you want to get to 400 I would just go straight to a SC42 billet and sell the sc38 but you will still require the headers and injectors so all comes down to money.

 

Nope, 380 is a good one on an STI a billet one will do better, but the traditional 'old ' one is 380.........

And they are not laggy [ unless knackered ] The 06/20g would be on a 2.0.
