Check my work before I call it finished

[DottySkee]

Hi All,

I'm achingly close to turning the key after doing an engine swap this winter. Couple odds and ends to tighten up/make sure is attached correctly and most importantly, no hoses mixed up.

I've scratched my head a few times with the difference between the rev 2 engine I took out and rev 3 engine going in as the rev 3 had been modified.
I'm hoping someone can give me 1 last piece of advice to make sure I haven't cocked this up.

The MAP sensor. I'm guessing this:



Hooks up to the MAP sensor? It's the only spare 3mm vac hose in that area (process of elimination ), from just under the oil filler. It's tough to see in that pic or get a decent picture. My hand is holding the 3mm hose that comes from it and it looks to be some sort of valve by it's shape. It's just to the right of the hose clamp you can see in the centre of the pic.

Do I hook this line up to the MAP sensor and away I go? I'd hate to get a line mixed up at the very end and cause an issue for myself.

If there are any extra helpful Scottish members who could come and double check my work and that everything is hooked up as it should be I could pay them in cake, tea and beer and would be eternally grateful!

Iirr one goes to the fuel pressure regulator the other goes to the map sensor dosent matter witch way round you plumb them in ..stock its outer pipe map , inner pipe fpr

Ah, so there will be 2 hoses down in there? Or do you mean the hose I have looping from the inlet manifold, one line goes to FPr and the other MAP?

From some googling, it looks like it's actually the FPR I'm pointing at and holdign a hose coming from there.

This is where taking lots and lots of pictures comes in handy. Never say "Oh I'll remember how that goes together!". Lessons learned and all that I suppose.

I was thinking of my old rev2 engine and guessed a rev3 would be the same I will go out and check my rev3 lump for you tomorrow

Googled a picture a yes its different , sorry about the confusion ...


pic ..

[2mad]

Just went out and che^cked the black hose fitting on the front of the manifold next to the throttle body is for the map sensor . the hose fitting picture bottom right is for the fuel press^ure regulator


Hope you get what i mean the up arrows point to them

[DottySkee]

Aha, I get what you mean. That explains the T piece taken off from the hose next to the TB (guesing previous owner took a boost gauge off from here).

I had guessed the hose I was holidng would be the right length, may just need to use a new hose to reach the FPR on the n/s of the car over from the o/s under oil filler.

Thanks for the help, I'll hook it up and may pop a picture back up just to double check I've done it all ok.

Wouldn't have got the car running without IMOC!

map sensor on a rev3-5 is the bottom left pipe/hose in your pic

[2mad]

Id be happy to take pics (all work done by toyota, so should be wright) .. as long as the relevant sensors have boost/vacuum you should be fine

[DottySkee]

Excellent, the loop off the inlet is for the MAP. I can take my boost gauge off that with the t-piece already there from the last owner.

Is the stock FPR located on the n/s of the car on the fuel rail? What threw me with that hose I was holding was that it was so short and the engine was pretty much ready to drop back in and run the way I bought it.

Picutres would be brilliant if it's not too much trouble. I'll nip over to the garage tonight and get a better picture of what I'm looking at (I'll move some of those other hoses out the way) to help me explain better hopefully. I'm sure I'mm have a bit of a light bulb moment when I see it and it will seem obvious.

Once this hose is sorted, I just need to fit the alternator, fill with fluids and see if she'll start. Taken me 5 months but I'm nearly there.

[jimGTS]

personally i would use a different hose for the boost gauge.
the map sensor is an important part of a rev3+, any wrong reading it gets (from say a leak/split in the hose at the boost gauge you plan to run), could send wrong signals to the ecu and ruin the fueling if not cause engine damage.


i use one of the empty ports behind the manifold, 1 is blanked off as standard, i use that one.


FPR, is drivers side on a rev3+. you must be holding the fpr hose for sure in your picture, there are no other hoses that size in that location other than the fpr one.
that fits to the nipple you can see in the 2nd picture posted by 2mad, you can see it bottom right of the pic, to the right of the hole for the TB to fit. its also tiny, you can just make it out if you look closely.

By the looks of it hose you are holding goes to fpr. I have circled where it goes in red. If your fpr is not in stock location you can blank this and take a feed from someplace else.

The other one i have circled black goes to your map sensor. As jim says, take your boost gauge feed from a separate source.

I am just over in fife so can help you if your stuck.

[DottySkee]

Thanks for the circled pic. I've made a slight mistake elsewhere by that then!

Explains the length of the hose I'm holding, perfect length to go to that nipple. I think I've mislabelled another hose when I took my old engine out (everything left attached to the body that I removed got labelled. I have a terrible memory otherwise). Thanks for the offer too, I'm going to see if it starts for me on sunday. If not, I may ask for a bit help.

I'll probably use the same outlet for the boost gauge too then, good point about any leaks, didn't think of that.
