Differences in rb25de engines

[crooser]

I have been meaning to ask this for a while...

The R33 GTS25 manual specs say 190hp

The R33 GTS25 Type S manual specs say 200hp

Does anyone know how the extra 10hp is found?

A lot of ppl say the RB25DE doesnt have VCT. Mine (type s) does.

Could this be the 10hp gain?

any ideas?

no the ones that dont have vct are the r32 n/a rb 25's the power is found with better tuning of the stock ecu I would think and possibly a freeer flowing exhaust so why all the questions are you consideringig a stronger rebuiild for your motor?

I'm currently shopping for an 25det/5spd for a transplant.

Should make things a bit more fun, plus then i can stop worrying about IF/when my motor will spit the chewy

Although there are no signs of it throwing a leg out of bed yet.

let me know if you hear of a good deal for an 25det/box combo or a front cut

10hp gain aint much for the rb25

a nice aftermarket cat back can net you u close to 20hp.

im guessing a combination of small things like ecu tuning and better breathing.

[crooser]

you are right... its not much, but it is free after all.

do the conversion dude its worth it i reckon, im in the middle of doing mine now

[crooser]
