i know there are numbers of bolt on option
for our loving lexus isf..
the question what is other options ( realistic ones )
most people know n most people do would be
intake + filter
exhaust + header
possible ported manifold

is there any other option ?
without ( NOS )

And i am pretty sure I could not find the ECU tune
or well built forced induction kit for us ( personally it is not a common set up compare to other maker cars )

what are my option ? I did all the bolts on without NOS n Ported intake manifold

any other power mods available ?

thanks in advance

 

Not yet. Maybe never. Production numbers make it difficult to justify any big mods without being able to tune, and so far, no one has been able to produce a tune for the factory ECM on a US model.

 

hopefully with the RCF, we may see something trickle down to us... we'll only pray something good comes.

Pretty damn lonely being the only 5.0 that doesn't get ****...

 

Is it too early to know what the differences are with the RCF motor?

 

But thing about rcf..
I dont really see the point the reason i choose
Isf was more like hey m3 4door n things not gonna break easy..
But rcf has two door at weight about 3700 ?
When new m3 joins the twin turbo
Rcf will have a cf package with dumb high dollar option
I am lil worry that our isf will be just AS IS with what we have

 

True it is so sad
But look at audi v8 s4 the old ones r now getting supercharger n tune from apr tuning company as well as the r8 i saw it from local meet
Really isf is very hard to tune
