barneybrendan Posted July 16, 2011 Author Share Posted July 16, 2011 (edited) I now have an ls400 throttle body to play with.It looks like it will fit just in the space available.Need to get some thick plate now to make a flange for it ive run out of scrap.What are the 2 actuators for on the side? Just hit the first snag the celica cable is longer on the ends. Edited July 16, 2011 by barneybrendan (see edit history) Quote Link to comment Share on other sites More sharing options...
barneybrendan Posted July 16, 2011 Author Share Posted July 16, 2011 Hopefully one of these should sort the cable issue out http://cgi.ebay.co.uk/THROTTLE-CABLE-END-FERRULE-BULLET-KITCAR-BRISCA-1-/280492612147?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item414ea99a33 Quote Link to comment Share on other sites More sharing options...
Guest ugp Posted July 16, 2011 Share Posted July 16, 2011 The two actuators are just for softening the off throttle > idle. I've removed them both, no trouble at all. Quote Link to comment Share on other sites More sharing options...

Guest ugp Posted July 16, 2011 Share Posted July 16, 2011 You can also remove the water ways from the TB, they just pull out with a little heat. As for throttle cable, I'm using a stock 2jz NA one, I've just removed some of the outer cable cover to expose enough inner cable to provide the required travel. If you find something more suitable, please let me know Quote Link to comment Share on other sites More sharing options...
barneybrendan Posted July 16, 2011 Author Share Posted July 16, 2011 im using an st205 cable the problem with that one is too much inner cable,i have descided to cut the end off and shorten it then fit a brass end on there.I have to use a long cable as the throttle body is sitting where the battery is normally.

David P Posted July 16, 2011 Share Posted July 16, 2011 I removed the throttle-up actuator yet left the soft throttle stop on mine. Quote Link to comment Share on other sites More sharing options...

barneybrendan Posted July 16, 2011 Author Share Posted July 16, 2011 thats probably what i will do ,at the moment it goes to a catch can. I think there is some forces at work to stop me getting the car finished as ive just managed to break the casting that hold the tps to the main body,ive just put some jb weld on it so see how it is in the morning.

David P Posted July 16, 2011 Share Posted July 16, 2011 That's their favourite revenge if you drop them. Be sure of that little casting, because failure at WOT could cause another Toyota runaway. Quote Link to comment Share on other sites More sharing options...
barneybrendan Posted July 16, 2011 Author Share Posted July 16, 2011 i was pulling the waterway pipe out and crack.Lets hope the jb weld holds up then.In an ideal world i would just get another throttle body,but i cant aford that at the moment.

David P Posted July 16, 2011 Share Posted July 16, 2011 All of the metal pipes in the Lexus t.b. are fixed far stronger compared with a Supra t.b. I just pruned the water pipes off with an angle grinder. Quote Link to comment Share on other sites More sharing options...
barneybrendan Posted July 16, 2011 Author Share Posted July 16, 2011 (edited) I was thinking of just getting the grinder out ,Oh well its not surprising it happend though. Just checked the the throttle body this morning and it seems like the jb weld has held firm over night.I tried to pull it apart as hard as i could and it didnt budge.

barneybrendan Posted July 21, 2011 Author Share Posted July 21, 2011 Just fired the car up again after phase 2 and i have come across a bit of a problem.the car will start but the top silicone pipe is collapsing and cutting the engine out.If i was to keep on the throttle i can keep it running, but the pipe is still collapsed. The throttle body is now before the charger and the bypass valve is after the throttle body.The bypass valve is opening properly on tickover.What could be causing the pipe to collapse.I took the pipe off started it and the car revved like mad. apart from the problem the car now sounds a lot better than it did when i had it dyno'd Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 21, 2011 Share Posted July 21, 2011 Well, at idle it will pull a strong pre throttle body vacuum, as the idle control valve (bypass valve) is only flowing a tiny amount of air and the engine is wanting lung fulls. I think it will need hard piping or flexi pipe designed to see vac and pressure, up to the engine side of the TB. Quote Link to comment Share on other sites More sharing options...

I think it will need hard piping or flexi pipe designed to see vac and pressure, up to the engine side of the TB. this is how its set up. throttle bodthen hard pipe to the charger with the bypass valve inline,then the supercharger the outgoing pipe has a 40mm pipe connecting it to the bypass valve.It then goes through the intercooler via silicone bends and hard pipe.There is also silicone bends on the other side of the intercooler.The hard pipe then goes up to the original na tb which has had the butterfly removed but still using the idle control valve.the pipe that is collapsing is the silicone bend that connects to the na tb. The confusing thing is everything ran fine when i was just using the na tb after the supercharger.

barneybrendan Posted July 22, 2011 Author Share Posted July 22, 2011 (edited) DUH i now feel stupid.I didnt think obout the icv and basicly havnt got one plumbed in.Cheers pudsey (mark) for pointing that out to me.Basicly i left the original na one on the na throttlebody that i removed the butterfly from and thought that was all i needed to do.so now i need to feed air from before the v8 throttle body to the na icv some how.The other thing is does it actually matter where the icv is located,does it need to be before the charger for instance or can it stay where it is after the charger.Also the na body has 2 discs that look like they can be removed to put a fitting in for an air feed. Basicly i was starving the engine of air.We removed one of the bungs from the na throttlebody and fed a pipe to it from infront of the v8 throttlebody and the car ticked over at 2000rpm .

David P Posted July 22, 2011 Share Posted July 22, 2011 (edited) Barney, There are plenty of pics of how I have configured the ICV on mine, here's a couple. The additional air filter looks trendy, but I cannot use it because of the HHO. I will be using the set up in the second pic. This will allow the ICV to draw from before the butterfly and prevent a build up of HHO at tickover.

barneybrendan Posted August 4, 2011 Author Share Posted August 4, 2011 fitted the old na throttle body back on today.I had the internal hole plugged and welded and the fitting tapped in to take the pipe.Need to try it now to see if its still sucking my pipes flat.If so its just another delay in having to get all the silicone replaced with 90 degree alloy bends and have them welded to me existing pipe.

barneybrendan Posted August 5, 2011 Author Share Posted August 5, 2011 It lives again but all 3 pipes are sucked flat so will definately need hard pipe welding to the existing pipe.Bloody pain as i cant weld alloy. It will need mapping again now aswell,so will be giving AFR a shout again for the 3rd time Quote Link to comment Share on other sites More sharing options...
