Turbo B16 Issues

[LVNIT]

Well fcuked if I know whats going on, its still quick none the less, but its not what it should be

Im running 11psi ffs, the thing should be a rocket

The tune is defaintly not optimal in the upper rpms. but man, the part throttle and low rpm values are spot on. This thing drives like stock, comes into boost like stock and really impresses me.

Its just teh topend. I say he will see a big improvement upping his exhaust size also. Its omly running 2.25" catback atm (2.5" DP) Either way, i think a dyno tune will do it wonders. It really needs some timing up top, but needs to be added in a controlled environment .

if its a .48 exh then yes.
If i was in canberra i'd tune it for free to prove the point.

good to hear ur keeping the car. You'll love it when u get it sorted.

lol
hey pro ecu wanna tune my car for free to proove the point lol???

i do agree with james and im sure you know yourself that a better result can be acheived with a better turbo more suited to his application and same goes with the exhaust size mentioned by weq......you are no longer dealing with N/A thus the exhaust size needs to be upgraded to the appropriate size. i also agree with proecu, i dyno tune is essential .....help acheive optimum performance with out pushing the engine over the edge.

Haha go my sick part throttle and low rpm values Getting adjustable cam gears like you said and off for a tune.

There is still something holding it back though

you'll be suprised how responsive turbo cars are to even a slightly leaner mixture.

Dont stress too much, get on a dyno and go from there.

Some people have mentioned a blocked cat, any merit to that claim?

Edit: It would explain why the car feels like its hit a brick wall, all the extra back pressure on the engine...

[pillow]

Have you got a different cat to try out? You have a 2.25" catback right?

[LVNIT]

Just going to take the exhaust off from the dump, see how i go

Sorry I didnt come out last night mate, had to go out for a family dinner

[pillow]

That's cool man, few cars came out, wasnt too bad.


Do you want to try a high flow cat? It's just that driving around with no exhaust and no cat for however short a length of time runs the risk of a massive fine ie 10k for no cat

I've got a high flow cat oin my civic you can take off and try on yours to determine if it's the problem or not.

[LVNIT]

Just going to take it off and drive around the block to see what happens

10k fine is massive :P

[pillow]

Fair enough, you gotta take me for a ride one day

Well spent a few hours this weekend on the car in an attempt to work some problems out..

The good: Replaced the old cat with a custom high flow item, checked over all the exhaust for blocks while i was at it. Took the car for a drive and it turned into an animal, the car wheel span everywhere once i hit vtec. So I can only imagine what it will be like once i piss off the small 2.25" exhaust, which in some places is actually 2" and get a larger 3" exhaust on

The car will also be off to Dyno Dave in the near future for a tune on possibly Uberdata but more likely Hondata

The bad: The turbo is completely fcuked.. On acceleration blue smoke piles out the exhaust, even on de-acceleration it does the same thing, idle is the same too unfortunatly. Thats the problem when you buy second hand turbos, lesson learnt for next time

A Garrett T3/T3 57trim .63ar has been ordered so that should fix up that problem.
