Turbo Kit Identifcation

[shnazzle]

We don't know who fitted them probably first place that fitted the turbo kit but I don't know who that was, he has been lucky not to lean out on that low flow injector and probably running a little richer everywhere else to compensate.

Got some new Bosch 470cc ordered this morning just need to get some plug adaptors now.


Wait till you see the state of the air filter I took of the car, surprised it even ran if that's badly clogged!.....I guess being tucked behind rear light makes it hard to inspect but its well overdue an inspection and I doubt it will clean up now so probably replace that as well!

It's a very very dirty place to put a filter as it turns out. 

I remember the state Helen's filter was in on the SP240 when we got it. I'm surprised it ran at all,just like you. 
Had the extra fun of having to remove that damn ducktail spoiler, to remove the light, to remove the filter. Nightmare.

Yes it seems so  and i will be working on improving this area of kit if i can.

So what's your rough total budget for this? I sometimes toy with the idea of a turbo, not sure how much of it I could DIY though.

The imo best is sticking to the OEM layout and stay within the max power limit this sets.

I want to be under £3k all in which "should" be easy enough as im well under that so far at just over 2k spent, depends on clutch i guess as im expecting to have to change that which will add a few hundred on depending what spec i go with, i dont know what my current clutch is or how old it is either but car as 103k miles on so if original and stock spec its not going to be happy with 200ftlbs or more! lol..... Matt tells me stock clutch in good health will just about take 200 but its right on limit so i expect to have to change it, i will be starting out on actuator pressure to get things settled in which should be around 180/180 im told and stock clutch can handle that if not abused, we will see.

This kit puts the air filter just behind rear light in front of the stock air feed coming over from side vent so similar to oem and well away from hot manifold/turbo, im not sure why it gets so dirty here as the stock pipework which is in same place doesnt, maybe having the filter right there is sucking dirt up from wheel arch area i dont know and ive yet to investigate that, maybe some extra sheilds will be needed to help with this we will see.

Maybe it is not the location but the aumented quántity of air filtered. Suck through 50% more air and that is 50% more dirt.
Also, the inner wheel plastic is not air tight and the slightest lowering of air pressure inside will see dust from the tyres sucked in.  Enlarge the entry behind the battery, under the fusebox? That is after all the same size as the OEM air duct through the wheel well so probably quite restrictive for the larger quantity of air needing to pass through.

This was Helen's. Aside from the obvious big hole, it was just thick with muck. I blew through it and it made my cheeks poof up, that's how blocked it was You cannot view this attachment.

On a side note it seems to have done a pretty good job of filtering the particles as the hole shows nothing deeper in the material.

[thetyrant]

Nasty looking filter!  mine is worse I think  will get a picture, going to get a new one ordered up before I fit the kit as not worth cleaning it I don't think, although its clean inside so been doing its job well just such a mess and I don't think I can bothered trying to get it clean as probably wont come perfect.

Unfortunately not so much so. The inside of the filter was gritty. Maybe bevause of the massive hole

Don´t clean.
You want a larger suface anyway.
When sucking in say 50% more than the n.a. engine, the fliter should ideally be 50% larger than the OEM one. Should be space for that.

These clogged filters made me think about the air flow. With the OEM duct taken out, she space in the rear quarter is a non-hermetic plenum chamber with the entry behind the battery and many leaks.
Dust from the tyres wíll enter.
The more air is sucked from the chamber the more will enter that way, so it is more of an issue for you f.i. guys but applies to anyone with a deduct. Had not thought of that.

@shnazzle; could be. The material itself seems to be clean further down.
Btw if all the particles are stopped at the outside, the filter material is not ideally suited is it?

Im not going to clean it   what makes you think its too small ?

Here are some pics of the filthy animal haha





And inside which is pretty clean to be fair!

It was a cheap ebay filter from the looks of it. So no, the filter was only ideally suited to the bin.

Jesus that's dirty

[thetyrant]

It is isnt it!  nasty indeed.

Probably replace with once of the Ramairs as below link which is just very slightly (10mm) bigger OD on fat end but otherwise same size, just need to check space available once i start fitting the kit, plenty of air flow for 300+ hp so should be enough

Did a good job though.

As such the fliter itself is not the culprit if perhaps small.

One staged solution is a (preferrably sticky oiled) foam ´sock´ over a the finer filter. That would keep the courser particles from clogging up the outer layer.

As to the amoúnt of crap, that is another issue not tackled by whichever filter.
I think it os dust from the tyres being sucked into the ´plenum chamber´.

It appears (could be wrong OFCOURSE!) to have less filtering surface than the OEM cartridge and it should have 50% more at least.
Don´t base yourself on the filter manufacturers data: They are the sellers!

Best to base yourself on the OEM filter and add as much surface as you want to add hp. Reemeber that ány resistance = power left on the table.

If you would extend the intake duct with a shallow elbow, you could have a quite hefty tubular filter parallel to the inner sheet metal.

I appreciate your trying to help but im not sure how you come up with all this when you dont have the facts to hand ?  you have no idea the size and area of the filter ive removed from this kit so you are just guessing critical information and coming up with incorrect assumptions.

I have both filters in front of me and a tape measure, the cone filter i have removed has more than double the open area of stock panel filter, the stock panel filter has deeper pleats so the filtration area % is very good for its open area size like most oem filter giving long service life, the cone filters filtration area is not as good % wise due to shallower pleats but its certainly capable of flowing a lot more air that stock filter (when both are new) and has proven itself good enough to keep dirt out and make 230hp on this kit.

Also for reference the stock panel filter is clearly capable of flowing a lot more air than a stock 1zz can consume, at least enough to make 190hp as same filter is used in the 2zz celica, maybe even the 215hp corolla compressor but im not 100% sure on that one.

Anyhows i will be replacing with at least same size filter and possibly looking as some shielding if it dirty's up quick, however i dont know how long this filter i removed has been on or what sort of environments its been used in so i may not have same problem, or at least not so much its worth the hassle of engineering a solution, if it lasts a year then im fine with just replacing it at that point

Now to get back to swapping over the engine harness

I stand corrected.
