Hi just wondering if my car which currently has a VF26,27 turbos on could fit on a VF 32,33 which is what i thought the car came with when i bought it and having a look online i can barely find any info about it, the car is currently running about 230 hp, 240nm torq tested on the dyno wheras it should be making around 276hp and 340nm tq and idk why as it all appears to be working fine and nothing being wrong with the turbos and cant seem to find the problem with it if anyone has any suggestions what the problems could be please let me know, i think i have a rev b which is hard/impossible to tune with the factory ecu and would it be possible to put a tunable ecu into my car for a decent price, any replies would be greatly appreciated as i dont know much about cars as this is my first car

Reason: forgot smth
Yes it is a revision"B" (Applied model code BE5B....) and built in November 1999
Standard OEM turbos for this model are VF26 and VF27.
The ECU could be any of these three listed below, although item 2 Japanese "note" translates as "massage equipment set" ??
Probably an 22611AD984 (code 40)
She is coming up as 280ps so somethings wrong.
The automatics iirc were derated a bit cause the gearbox's weren't the best.
the turbos work and kick in perfectly, had them checked and were fine and had it on the dyno, but just don’t generate that much power and in general the car works perfectly but you can feel that the power isn’t quite what it should be and idk why

Might be asking a silly question but would it be possible to put an ecu from a rev d into my rev b and be compatible as it’s Tuneable/ is there any other options
I've not driven one of these but why do you think it is down on power if the turbos are perfect as such.....
have you got something to compare it too?
Also who have you asked about tuning one of these.....
I think some mappers equipment recognises some JDM ECUs.
But maybe someone with more information will know.
Cheers
They have a black box full of solenoids and pipes. This is known to be troublesome and causes a situation called the valley of death (VOD) It pains me to say Bob Rawle has had success with mapping these but if it involves getting his hands dirty forget about it.
Ring this guy next week and he will know if it is or isn't possible to tune your car.
I have dropped him a email thanks and to answer your other question its because i put it on the dyno and its not making what i should be saying and the car works fine and i dont see any faults but i barely know much about cars but ive had it looked at and no one seems to know just hoping someone knows on here why im not making the right amount of power

Your not reading the replies properly. I know you have a manual as that is a manual gearbox code. The rest as stated is correct.
Maybe the turbos are just worn out....the blades become damaged over the years and inefficient.
will still kick in when supposed to.
20 years plus on original turbos.
good luck 🤞
There could be a whole host of problems that would effect power, even with everything appearing to work correctly. What's the compression across all the cylinders? How much boost is it making?

It’s making 14 PSI at the moment and I’d have to test the compression

🤣 I’m crossing my fingers too, the turbos were checked for hotspots and any damage and they were in pretty good condition, when I thought the turbos went it was actually an actuator what I got replaced about 4 months ago as it had a small oil leak
Should make less than 14psi on the small turbo and more than 14psi on the larger turbo.
Do you know how long it's been in the country? Could it have been mapped for 95ron?
it was imported in 2021/2022 and how can I check what type it’s been mapped for, on the dyno graph it’s only given me 1 psi number so I’d have to check myself , thanks for the help
Did you buy it privately or trade? I'm presuming that it's had a map tweak for UK fuel since it's been imported, as they run 100ron in Japan, so it's pretty much standard procedure for imported cars to be adjusted for UK fuel. Previous owner could have filled it with 95ron and had it mapped accordingly to save money. Would account for a drop in power. If it's a private purchase, can you contact the previous owner?
Check the compression and then give it a full service - oil, filters, plugs, maybe fuel pump, check for boost/vacuum leaks etc. Then find someone who can properly dyno map it for you.
Obviously not going to listen, black box with multiple vacuum pipes going into it on the O/S turret. Check all the pipes and possibly a smoke test. Renowned for giving trouble. The cars aren't quick anyway they're an awful weight.
