I have a t2 currently running maf, i don't have an air filter because it won't fit because the radiator is in the way, can i take out the maf and connect the air filter to the turbo would the car run?

 

Ouch!

 

You need the afm and definitely an air filter!

 

To prove this, vaccuum a rock up with your household vaccuum and listen to what it does, now imagine what it would do to your turbo.

 

water alone hiting a turbo blade can destroy it. you MUST get a filter on there.

 

unless u r running a standalone, you HAVE to have the afm/maf. the ecu NEEDs the signal from it to gauge the amt of fuel to disperse.....rteks are boasting removal of the afm soon (this summer). but as i said the only thing at this point is a full blown standalone


edit: how much water? i have an oil leak on the cold side which distributes oil throughout my tid. it seems to run fine, except a tad of lag, otherwise... But i agree, dirt + oil/water and time= a major blown turbo. I am nervous about the oil leak, that instead of upgrading my ecu (rtek and 2ndary inj's) im considering getting a bnr stage 3.....which reminds me,..... (I know a lot of people are thinking to themselves LEAN BITCH, but my philosophy is a 34mm wastegate, unless that inadequately controls boost which ill start a thread about here in a sec)

 

Well i can't install an air filter, theres like 1 inch between the maf and the radiator, i am running on stock ecu by the way, what should i do then now? the afm and the maf is the same size, and whats the difference of the 2? I heard that maf can an extra 2% more air flow and thats about it, also i am gonna need the maf adapter to the air filter.

 

then you need to move some stuff around. stock has the MAF and a filter along with everyone else using stock ECU.
that or you can spend thousands of dollars repairing everything when the bits of metal that used to be your turbo fly into your engine.

 

are you running the stock tid? get a prelude tid, and cut it up as needed to fit...i have relocated my resistor relay for the fp to the back of my car, so i have plenty of room for mine, and i have an SS filter (didnt wantr it to rust, its a k & n ripoff but still good, keeps my **** clean except for the oil leak in the cold side of the turbo). I'd say don't risk it... Its hell if you get the turbo dirty and something flies in there etc. I ran mine for a month (on and off driving no DD, but i feel like an idiot for doing so, now that i look at it). be careful, and id say not worth the risk.

edit: when i say prelude tid, i mean an intake off a 93 honda lude. apparently from what i have seen they are the best fit, and cheap enough so u can cut it up and do what is necessary to it. I guess my next question would be are you planning to do a true cai? If not thats cool, i havent yet, but i saw the best idea in the form of a box that uses the hood to seal itself, and a pipe running where the stock one runs. search about cai's as that is a VERY prevelant topic on here.

 

so right now i have two choice, either to reweld parts to push the turbo and maf back more in, or to get a stand alone so i can remove the maf and fit the air filter.

 

How about a little realism here. Unless you're off-roading your RX-7, how is a rock going to get into the AFM? If there are rocks flying around your engine bay you probably have other issues...

It isn't dangerous to drive around without a filter but over a long period of time there will definitely be accelerated engine and turbo wear. As a short-term measure it's not a problem.

How has the turbo ended up so far forward? Is this an aftermarket turbo and manifold?

 

thats what i wanted to know. i have more room then hes does,and i have a t4 turbo and greddy manifold... but i still havent worked out my issue,with the tid either..

 

dirt roads are common in the US. even rain can do damage to a turbo. it doesnt take much to damage something that spins that fast.
A while ago i saw a turbo that the water injection kit installed into the intake. After a few thousand miles the turbo died. when he took a look at the blades they were all chiped and messed up.

honestly is it a risk worth taking?
and to the thread starter post pictures of your engine bay. Their is somthing odd here.

 

You have a front mount or no?

mount the AFM in the I/C piping........

NOTE - that dirty *** AFM is just for mock up.

 

umm go to home depot.

taht is how my old setup was. rubber reducer, two couplings, two plastic bends and a little rigging. all on the same isle.

 

 

i'll take some pics now

 

Dirt roads are common in any country but he never said anything about driving on them. If you drive along a dirt road without a filter you're an idiot. If you drive in the rain with no filter and no hood you're an idiot. Since this is a temporary measure only, I'm sure he's capable of avoiding those two situations. This is just common sense.

Water injection is completely different to a bit of ingested rain (even if that could happen). You cannot compare the two.
