A few 22R questions
Just a few questions regarding the 22re engine.
1. Looking for headers, and Im wondering if some of the Hilux fitment headers will fit properly or with minimal mods. I have heard both that they do, and do not, so was wondering if anyone had real world first hand info or a known set that will work.
2. Im deleting the EGR stuff and the smog pump soon, so that I can run extractors that do not have all the extra junky connections on them and declutter the bay.
I assume the smog pump can go, as can all the hoses and connections. I still plan to run ac and Im wondering where to draw the line with removing stuff. Ill obviously keep the whole ac system and the idle up solenoids and all that. Just wondering really if there is anything I need to know before attempting to remove. Anything thats really important that I should keep, that might otherwise seem tossable, tips for young players as it were?
I know Ill Minded just did up his 22r, but he has tidbits of info scattered around his thread and it may prove more cohesive if we can get a bit of a 22re tech thread going since there are a few people on here with the mighty RA65 now.
RJ70 bundera do, there are some for sale on here at the moment that were on an RA65. I tried Some hilux 22r and they didnt fit but cant remember if they were 2wd or 4wd or 22rc or 22re, almost certain they were the 2wd version and they fouled on the firewall becuase they didnt drop down far enough vertically.

Thanks, so you personally have fitted bundera headers to a celica?
No but refer this thread, bottom of the page,
they were on an RT142, same shit

Solid. Thanks.
Pretty much all of the emissions related items can be deleted without affecting how it'll run. The only thing that would be worth keeping is the cold idle valve located under the intake manifold. I would have kept mine, but too many of the moulded hoses running to and from it were hard and brittle. I do have plans to retrofit a simple solenoid actuated valve with a NC thermofan switch in place of the factory setup though once I sort out my alternator and any other little issues.
The main ones you'll be looking at will be the EGR and the manifold air injection systems. The EGR bits are just the few little pipes and valves bolted between the back of the intake manifold and the rear of the head and the manifold air injection system runs from the canister looking thing that sits behind the air box, runs under the intake manifold into some random valves and voodoo magic, then the two steel pipes that run around the back of the head and bolt to the top of the exhaust manifold. Any of the vacuum valves that are usually located on the top of the valve cover can be disconnected and the extraneous wiring tucked away. There is one which is the A/C idle up, which you'll probably need if you're keeping your A/C. In any case, I've pretty much gutted the whole lot and mine still starts and runs fine, aside from the lack of a cold idle valve, so it's a bit annoying until the engine warms up a bit.
If it's any help, you can see how much less there is hooked up on mine in the picture below. If you still have the hose that runs from the front breather on the valve cover back to the intake manifold (which runs through a port which opens up before the throttle plate), keep that. Mine was cactus, so while I had it blocked off in that picture, I need to put a little filter on it for now.
Compared to this horrid mess...
Don't hesitate to ask if you want any more pictures or any more details. I get a little lazy when updating my build thread at times, so I usually gloss over the smaller details, haha.
Actually, while we're dumping 22R tidbits, Kelpro urethane engine mounts (Part number: MT8153N) lift the engine enough to raise the sump about 5mm above the level of the crossmember; for those who run low enough to cream the sump on everything. They're a bit of a prick to install though, as you'll need to unbolt the mount bracket from the engine block slightly to allow the mount to get close enough to the crossmember mounts so you can pry them into place and bolt them in. Kinda hard to explain through words, but you'll get what I mean if you ever install them.
kelpro do urethane mounts, awesome!

Hey thats great info, thanks.
Yes got sick of pawing through projects and decided to build a tech resource instead.
Mines auto so I dont want to delete the cold idle features as it will probably stall while cold, so I'm going to keep that. I already changed out a weeping hose to it at great cost to my knuckles. Just being able to work on it is a big part of the motivation for binning the smog and egr stuff. The smog pump just sounds awful spinning away, kinda like skipping a steel sheet off the bitumen, if you put your ear to it.
Nice write up Ill minded, i plan on deleting the uneccesary emissions stuff from my daily Avante soon. Just went trhrough and replaced full gasket kit, rad, water pump, clutch, shifter bush, thermstat, timing chain, etc etc, the list goes on!
