Hey craigm1841, I guess you are online at the same time
You seem to replying to my replies as soon as i reply!!
Anyway, it's true that stock engines are tuned to less potential FOR RELIABILITY purpose. Make sure to last long(200k+).
That's why with bolt ons, engine mapping etc is perfectly fine because it's a minor increase in power.
However, JB3/dinan/whatever other mapping is not. It's a very significant of power increase. It's 33% more power than stock(if you go by under rated number bmw published).
Dinan mentioned that in order to qualify the warranty, 335 must equipped with a factory oil cooler and not all 335s are equipped from
the factory. Hmmmmm.
Factory turbo cars can be tune to very fast. Sti's, evo's etc can be a monster. But, they don't just increase the boost.
They do a proper tune, meaning upgrade other parts to withstand the increase in power. So stock turbo cars are not as cheap
as people seem to think.

i had a friend with an STI, he upped the boost with a remap/ecu flash, and the follow on work did seem never ending. bigger intercooler, oil cooler, waste gates, all that. and his car seemed to run like shit when he wasnt beating on it.... i dont know much about this stuff though. this is my first forced induction car.
so, we are up at the same time. work nights and just got home (got off early tonight) gotta get my e60.net fix in

if i am not mistaken, the way the turbos in the N54 are set up, you cant easily replace a turbo, they are actually somewhere inside the engine block. dont know if this is true or not, so if course this is a risky mod. i think for normal driving it would be alright, but i drive hard and this is why I havent done it yet.

I kinda knew that N54 would be very complex and won't be as easy as other japanese turbo cars to boost up the power but wow...
According to Dinan, even stock N54 runs a bit on warm side(engine temp) and recommend oil cooler in stock form if a driver is
run hard. But somehow they do not have one for 535i.

if what you said is true about turbo in N54, oh man... good luck to people who face the engine problems later

Silly Q again, but would one from a 335 fit? It doesn't make sense to me that a car with the same engine can't use SOME of the same parts on another car.
also, the longevity of the n54 motor tuned has been discussed further on e90posts.com.....
if you are seriously considering a tune, do yourself a favor and research on both e90posts and n54tech.com via the turbo/FI section

AFAK, yes a jb3 is universal, so it will fit between a 335i and a 535i, but confirm with Mike@N54tuning.com or terry @ terrance@gmail.com

Oh. I was talking intercooler/oil cooler and such. If there are parts like those for 335s, would they be ok on 535s? I know the JB3 is universal.

downpipes for the 335i are also different from the DP's of the 535i....
***so basically, 335i bolt on's will not fit the 535i

Also All 535i's have the AUX oil cooler in front of the Radiator , so at speed it gets much more cooling compared to the E90's which is located in the right front wheel well. The FMIC is up front and as Genetials stated the oil lines for the AUX oil cooler and the front air dam preclude a direct fit FMIC upgrade from the E90's same for the down pipes.
The turbos are basically on the block to improve the lag response, so for turbo upgrades ( which there are a few or they are in the testing stage) it is a PITA, and usually involves removing the guts

Terri was helpful and sent out another unit while the other one is on the way back to him. Anyone have issues with this, do you think it has to do with the new version 1.3 being out?

So with the JB3 and scoop/filter, how much HP can one expect to gain (running the default JB3 map and 93 octane)?
