How easily tune'able are they on standard internals?

What can they handle safely before internals need to be upgraded?

And what mods will they need to reach it?

Cheers

 

from what i hear not a great deal, was thinking of putting one in my 2003 wrx as i broke my engine but have been told by someone i full trust that a rebuild would be the better way to go and for the price would handle alot more power that the 2.5 std engine

 

hope u get a reply as im in the same tree
Ive got 1 with the type 20 kit (wasnt imported by litchfield though)
thats just miltek with sports cat and re-map thats 350bhp similar torque.
Im looking for more but dont wanna tinker with the internal gubbings.
Ill keep an eye on this thread

 

Im confused by your comments??
JDM is 2l was u refering to a 2.5l
not being rude just dont get what your trying to get across

 

400bhp i read same as the spec c ? they are all 2l ?

 

easy way would be to give litchfield a call

 

Try putting the thread in 'general technical' might be better or ask 'Tony Burns' (I do) hes got 1 and seems to have answer to most subjects.

 

400bhp is easy to get from one of the jdm 2ltr twin scroll units, 360bhp/380+lbs is also very easy to obtain (and cheaper than doing it on a uk car )

Can't remember who (ducks the slap) but there is one jdm 2ltr twin scroll engined car running over 500bhp on standard internals on here

 

you've saved the day again
How do we get to 400/350+

 

380 on a 2ltr?? I wouldn't have thought that would be "that" cheap. The 2.5 has bags more torque but usually less overall power?

At a recent rolling road day a load of the guys had tuned 2ltr cars (not jap though so maybe it's the twin scroll) and even though 2 of the guys had uprated turbos (and uprated everything else) and close or more than 400 hp they were still only getting 350-360lbft.. My STI has had a remap induction kit and fuel pump and straight through exhaust and although only 330hp its running 390+ lbft,

With a turbo & front mount I would expect 400 and 450ish? Although I would imagine the engine wouldnt last long without being strengthened.

 

Pants what car do you have?

And what mods

 

Im running a 2 litre twin scroll with 345 bhp & 400 ft/lb torque with a few minimal mods
