Hey all!
I've got a 5th Gen Celica that I've been working on for most of the summer, off and on....and I've been doing the 3sgte swap in my free time. It's been the single most rewarding experience in my life..amazing the stuff I never knew I didn't know. the little things I've picked up along the way have been excellent additions to my knowledge arsenal....fantastic experience, really. :)

WELL! Good news! It's almost complete(Can't wait! hehe ;) but the bad news is, I can't find any info on the st215 Caldina that its out of...and I don't want to mistakenly screw everything up here in the last lap.... I can't figure out exactly how the plumbing goes for what i believe are coolant hoses(different diameter hoses are causing me to second guess myself) and exactly where the fuel line(return? I believe) goes to.

So, my friends.... I give it to you...

and then a hole.... not sure if this is normal...comments?

Even pictures of other st215/celica setups that i've found dont have enough detail to see whats going on....so, Thanks in advance!!!

ps. I could post more pictures if needed... just don't want to kill the servers! :bigsmile:

Cool, welcome btw. :) You will definitely enjoy the car when you are done!

Tim aka 4thgenceli is in the process of installing an ST215 engine on his car as well, he might be a valuable resource for ya.

I will do my best:

1. PCV ventilation. Should route into the intake tract somewhere. A lot of people will install a catch can here to collect the oil vapours before they go back into your intake, keeping things clean inside.

2. Idle Air Control (IAC). Also goes to the intake. The ECU will adjust idle by venting extra air when needed. Or you can stick a filter on the end of it, or right off the throttle body if you wanted. Either way, not terribly important as long as it's not blocked.

3 & 4 are pretty tricky b/c I can't see where they are coming from...maybe one is for the factory blowoff valve but I can't say for sure....

Fuel rail one - is that a fuel line or a vacuum line? If vacuum, just to the intake manifold...if fuel, it could be the fuel return line going back to your fuel return pipe on the firewall.

The hole - that's where the distributor on the gen 1/2/3 heads sits. But since you don't have a dist. it makes sense that the casting is left the same. I would suspect it is still sealed, but having not seen one in person I can't verify. I might pull the valve cover off to make sure unless someone here can clarify (which I'm sure they can)

HTH!

welcome,
i have done the st215 swap into my st184. chris D is right. #3 is factory bov, #4 should be fuel feed line, if it is connected to the end of the fuel rail.
pic #2 is fuel return line, connect to return line off the firewall, last pic should be sealed with half moon shaped casted aluminum.

I'm doing a st215 swap also, do you have a wire diragram for that engine, or pin out for the ecm

Swap almost complete! Question, the PCV ventilation routes to pre or post turbo? I'm confused... the engine is running, but not prettily with it going to the pre-turbo intake. Thanks!

Toy8490- I just broke down and went with Dr Tweak for my electrical work... well worth the money. :)

Nice! Mind PM'ing me your cell # by chance? I have a few ?'s for you... stuck on a couple things on my 215.

Pre turbo is correct, you need an oil catch device
