Just about finished....

Yep, that piece of pipe is the MAF housing from a 1MZFE airbox... Was keen to have the whole airbox + panel filter in there, but it looked as though there was no way to make it fit nicely.



I've tapped a line into each of the intake runners, after the throttle plates.

These all tee together into one, which goes to the standard idle speed controller which is mounted on the underside of the airbox, that's where it gets its air from... So it's still getting air that has been 'read' by the MAF.



The intake air temp sensor is integrated in the MAF, so no problems there.

Dont take any of this as gospel yet as working great with standard ECU, it'll have to wait until I get the car running half way properly and can take it for a drive, to see if it actually works well or not. I'm planning on going 1ZZ powerfc route at some stage either way. (Hence keeping MAF)

HA! So what is that copper looking pin we have sticking out from the bottom of the throttle body? It's right before the butterfly.....I always thought that was the temp sensor....I know we have hotwire MAF but wasn't sure if it did air temp as well, would make sense because of the 5-wires.

I wonder if the the was the ITB's pull air into the engine might make the MAF read funny.....would be something to look at when the time comes. Another thing is that the ITB's have much better air flow, possibly pull more air in thru. I wonder if our MAF has certain limits as to how much air it can "read". If anything it might make the injectors squirt more than they have to because of the MAF reading so much more air being pulled thru.

Just an observation, but you might get bad read from your MAF because of it sitting so close to the air filter. I made a bit of a honey-comb out of plastic straws placed about 12" in from of my MAF to smooth out the air going thru, makes a helluva difference, especially for those of us running that Camry intake pipe!

Good job Roman, can you give me more info or pictures of the speedometer that you use. I need something similar for my 82 corolla.

[Roman]

Hi there, Thanks.

The speedo setup is easy.

Standard dash/speedo, standard speedo cable, and then the speedo sensor that plugs into the 6 speed was from a W57 gearbox... Standard speedo cable plugs into that!

And then it all works.

I'm not sure how accurately it's going to read though, but will cross that bridge when I get to it.

May have issues with the lack of speedo signal to ECU but we'll see. (Doesnt matter if you're running aftermarket ECU!)

That copper pin is redundant, if it's the one I'm thinking of.

I dont think so... bear in mind that people have run low boost turbo setups using the standard MAF within its limits, and also the V6 VVTI 1MZFE uses the same part number MAF. Which I'm sure draws in more air than a beams motor.

Yes, I have been giving a lot of thought to this.
I originally had a complete airbox, but there was just no way to make it fit on that side of the car. I'm just gonna have to see how it goes I think, I am kind of half expecting problems from it.

[WFX]

Nice build Roman, really liking it!!

[Roman]

Thanks!

Only thing holding it up right now, is getting the gearbox fixed.

Apart from that, and finishing panel and paint, (After test driving, making sure wheels arent gonna rub gaurds, or whatever) will be all ready to go.

[Edophus]

Good to hear it is close Roman!

I have a question about your propshaft, I have one from a manual celica xt, not sure what type it is, but would have been for a 21r engine, not sure the gearbox, but it looks like it is going to be a little short once i get the engine in the right spot, did you have any issues with it?

[Roman]

(If I recall)Mine is standard rear half, and front half from a cressida or something.

It wouldve been too short, but when I changed to F series diff, it shunts the whole lot foward, so made it sweet.

Auto driveshafts are slightly shorter BTW...

[daCoupe]

Awesome build! Wish we had those cars in Canada.

[Roman]

Well things been coming along a bit slow... In part thanks to me having a 7 month holiday off work this year, ahaha!

Back working again, so got some $$$ to get stuck back in.

Still having problem with the gearbox not wanting to stay in reverse properly, after 3rd time of having gearbox apart. Sucks! But meh, for now, will get it going anyway.

Painted engine bay, put some bits back in, motor/gbox back in this week some time...



But not before fitting an HKS 4-2-1 exhaust manifold, mean. (Only fits RWD setup)

I am also remaking my airbox so that the airflow meter is integrated into it, and the airflow is pointing more at the base of the trumpets, rather than kinda facing the inlet end. This will also give me more room to set up a good air filter, with a flexi in there somewhere.

I'm hoping to have the engine running again over the next weekend.
then sort out a few other bits and pieces and hopeuflly be able to take it for a drive.

Booked in for a trackday end of January, so gotta having it running, sorted, and road legal by then!

[Roman]

Well I got made redundant about 4-5 weeks ago, so no $$$ to get the car finished in time for January trackday. Bah!

Have been working on wiring and a few other bits though, but need $$$ for paint and a few other odds and sodds to finish it off.



Looks like I might have the wrong sized intake pipe, as have used the 1MZ unit...

Lame

Wont really know until the car is in a decently drivable state.

[MANDALAY]

Sorry to here about being made redundant
Looks like it just wont stop. I wonder if things will ever be the same.
Like to see her finished man.

If not it's no big deal, my old man is an electronics expert, I'm sure we'll be able to sort something out.

Unfortunitely, with all my years of Toyota experiance (Tech/Master Tech at a dealer) I cant tell you if the Carina has a speed signal generated in the head unit being that all my experiance is with USDM cars.

If you dont have a SPD signal from the head unit, there is a very simple fix. Im not 100% sure if you all got it in NZ but here in the States, the 91-92 SW20's had a seperate speed sensor for the cruise control. We never seemed to figure out why toyota did it as it is redundent when the car already has a SPD signal from the head unit... Either which way, you can probably get one from the states for pretty cheap if they weren't used in NZ...

It goes between the speedo driven gear output on the trans and the cable (Threads on the the drive unit then the cable threads on to it)... It'll have 3 connects (+12v power, ground, and signal) obviously, +12v to ign. power supply, ground to chassis ground and the signal to the SPD signal pin at the ECU and problem solved....

The unit works pretty much the same as the magnetic REED Switch's in the Speedo head unit, but its electrical instead of mechanical (obviously).

[Roman]

OH wow, that's awesome news! Thanks.

That's the perfect solution to my problem.

YOU JUST GAVE ME THE #1 BRILLIANT INSIGHT!!!

so I have been wondering since forever why the hell the RedTop BEAMS SPD signal goes to the Gauge Cluster *first* and not directly to the ECU. It MUST totally be for the cruise control if it's looking for the SPD signal....man I feel stupid LOL!

Dear Romanovski,

That box be made of fibre-glass, chop-cut-rebuild! This time follow age-old advice, think 3 times, measure 2 times, cut once...


Next your reverse issues....you know, I had the same problem, thought of taking my S54 apart but then thought: "Hey perhaps my linkage isn't doing something right" low & behold it was indeed....turns out my linkage for going into reverse was off by a few millimeters....

No, 93 and later cars all had electronic speedos the VSS (Vehicle speed sensor) opperates different on these. The VSS outputs a +12v digital pulsed signal. The ECU's including the Cruise Control, Enigne ECU, and P/S ECU (if you have speed sesitive powersteering) all look for a negitive pulse (pulsed ground). The Speedo Head unit conditions the signal (inverts it) for the ECU's to recieve the proper signal......

Wish someone would give write a threaf on this . Call it 101 basic , beacause i would love to know what you guys are talking about.
Hey Puretone unleash all that energy you have and start writing !!!!!!!!!!!!!!!

what on MANDALAY's (No not god, god probably drives a Ford or Chevy, or so Chevy would have us believe 33Mpg my rear axle!!) Green Earth is "write a threaf" mean??? Some aussie/NZ word?

"beacause" best new word on this forum EVAR!!1!'
