a TD06-49 from lateral performance....that will just about guarantee it. Dont be fooled in to thinking that a 20g will do it, as without fuel additives it may not make it very often.

On an STI I think a 20g will make 400hp without additives, but it needs everything else to work, you can't expect to rely on a turbo to overcome shortcomings in your exhaust, induction or cooling. I think with the right car, you could get over 400hp from an 18g without additives.

I see your a momentum dealer from your homepage. What do you think of the ej5-40t to replace a broken vf34.

cheers.

What about this from Andy F?

AFP5-20 - this is also a variation on the TD05. This time fitted with a much larger, high efficiency 20G compressor wheel and compressor housing. The high efficiency compressor allows the turbo to run at a lower rpm whilst still producing boost. This results in similar spool up to the 5-16 but with a 50bhp increase in airflow capability. This was the turbo used on our own RA to produce 440bhp (running fuel additives) . 400 bhp is achievable in conjunction with full supporting modifications .

This turbo is very effective on 2.5 conversions with 1 bar+ boost coming in around 2600rpm

£850 new or £550 exchange (includes 12 months warranty)
