92nsx's supra build

[funky_monkey58]

Shit Rob,

You should just start over on a manifold. Or rotate the q45. I have mine in a different position and it seems like it will be fine.

Just let me know when you want some help.

 

[92nsx]

Thanks Sean.

I just got done hacking the crap out of the Q45, just now. Now it will clear the the hood but need to modify the alt. bracket. (shorter) This is the last straw with this piece of shit FFIM from tubbie :nono:.

If this dosent work out probably just go back to a OEM intake manifold setup, unless I find a great deal on a FFIM THAT WORKS, lol.

But we will see how this works out.

Bolt-on, made in Minnesota. You can't say no.

I didnt know they were working on one. Nice find, I wonder what there price will be around? But not out tell summer, that kind of sucks. Umm..... I wonder if 2 piece or one. I know the one piece FFIM's are a pain in the ass to get to the rear bolts. Need to send a Jack a email for some more info.

 

[funky_monkey58]

Maybe we should all plan a trip down to stillwater. I know between the four of us supra guys in our area we could bring them some nice business.

Sean & Emilio stoped by yerterday and last night Played musical turbo's for the last time (remove mine from Emilio's car), got mine back on my car and Emilio got his new turbo installed on his supra.

Put back together my supra, with the Q45 TB. & BAM, she idles like no ones business!!! Perfect, except for the "loop" with the 272 cams. I even had the idle down to 750 rpms. I havent driven it yet but the throttle seemed responsive, and everything look to be ok. Around 42-45 psi of oil pressure on cold idle, volts looked great, once warmed up the temp held steady, oil temp only came up to 140ish but It only idled for around 10 or less min.

And all of this and I forgot to hook up the TPS, LOL. Once I bolted everything up It must have slipped our minds. Opps. We'll get it hooked up later today if I get back out the garage.

Now on to the next problems, I have super low vacuum on idle only 10 inhg.!! Im worried that it is not enought for the brake booster. But once I get the throttle cable back on we will find out, when we take her for a spin around the block.

Also I noticed I had 42 psi of fuel pressure when it was on idle, can any one say a little high, lol. I feel that it is caused due to the low vacuum and FPR not having vac. to pull it down to 32ish. But I will get a adjustable one here soon and get her installed.


The saga continues.............................................

It is going to be a one piece. They are trying to keep it around 900 bucks. And the reason that it is not out til summer is Greg (the mastermind behind all of the custom mad stuff) just got out of the hospital after having back surgery.

Well last yersterday I finished up the couple loose ends; throttle cable, downpipe gasket, battery; blew out the vac. lines free of coolant. Went to start it up and BAM another throttle body vacuum leak This time it is the flange from the POS FFIM, (yes, another set back due to this FFIM) But it dose idled fine, but once I try to hold the RPMs at 1500 or so it dose the whole jumping thing, up to 2000 down to 1000, then back up to 2000 rpms, ect. The only code is 52 so the TCCS should be happy with the TPS and 42 psi of fuel pressure for now on idle.

I am hopeing the eratic rpms once off idle is caused due to the throttle body flange leaking, but we will see once I get that fixed. BTW I just reinstalled the NGK's (heat range 7) for now, I forgot to pick up a new set at the parts store.

What continues............................................. THE SAGA

Rob: Sorry no real input as I haven't worked with much of the stock GTE gear I went full standalone pretty much from day one.

 

[92nsx]

Yersterday I installed new, longer, bolts with nuts for the throttle body, crancked them tight, and no more air leak. Doubled checked everything and she started right up and ran pretty well. I was even able to drive it for the first time in almost 2 years. First I drove it around the block and POOF smoke every where!!!! Turns out the the coolant hose running from the head to the heater core valve on the firewall blew off and blew coolant every where. The plastic where the hose attached was broke right off So for now I just by-passed it and took her for a quick drive up to Sean's shop. While I was at the shop I noticed there was some coolant on the floor coming from my car, but the radiator and over flow wasen't low, so I dont know if it was still dripping off the frame from when the coolant hose blew off, but I will look into it today. I put on a whole 25 miles yersterday.


I still have stupid code 52 but I will look into it later (I feel the knock sensor wire is unhappy). Today I think some new plugs, and exhaust gasket for the cat will get put on and even put the interior back together and put some more miles on this motor. I have one pic on post 9 and will update that post later with more pics.

All i have to say is a Supra drives weird, compared to my V. The clutch feels funny(will try and bleed it more today), the stearing is way to easy and to much free play. The throttle has a sticky point right at first(no DBW ), the 7m is NOT a quick reving engine( you touch the throttle and she revs up to2500-3000 rpms an dslow t odrop back down), and the tranny shifts harder than I like.

The 3 gauges in the piller pod is really ANNOYING at night, there way to bright ( pro sport gauges, need to find a way to dim them at night, Im not changing color on them right now there just white)!!! The Nav unit in the factory location is to low, and I think she rides smother than my caddy.

Thank you; Sean, Emilio, JJ, IJ, jdub, poo, figgie, rennat, zum, doward, facime, nashman, annoyingrob, and every one else I'm forgetting for the help in the last couple years. Im sure I will need more in the future.

Not sure what your other car is, but keep in mind hydraulic clutches to tend to feel differently than mechanical clutches. Also, there is an adjustment procedure for the clutch pedal you may want to look into (TSRM).

There is bound to be a bit of free play in the steering if a lot of your components are ~20 years old. Make sure your tie rod ends, steering rack and steering link joints are all in decent shape.

From my experience the 7M is a slow revving engine. The engine inertia vs torque out put before boost is not too impressive. However with a code 52 your ECM is no doubt retarding ignition timing so that is probably making the engine rev excessively slow.

The transmission will shift hard if the clutch pedal is out of adjustment, so like I said double check that. You can also try running whatever oil people are recommending for the R154 these days if you are not already. Redline MT90? And of course, there could always been worn synchros.

 

[Poodles]

Check the steering rack bushings especially. If you have PPS (forgot what year you have) then at low speeds it should be pretty light to steer.

There are ways to make it rev better, but a boosted engine won't have the response of an N/A...

 

[92nsx]

poo 89
yep the PPS is hooked up and is super easy on idle. I think it is just something I need to get use to in the supra.

I updated pics on post #9, new exhaust gaskets, fresh plugs, parts store was out of NGK's so had to install autolights for now :cry:, o-well they wont be in there long maybe one tank of gas, lol. Also put the interior back together, and removed the under hood insulator since it was soaked with coolant from yersterday.

Now it is time to fill the tank and put a few more miles on it this afternoon!! Hope everything goes good.

Side note are there too many pics on the first page where it takes to long to load, and do you guys/ gals like all the pics on the first page?

 

[funky_monkey58]

It was a pretty site having a diving running supra up to the shop under its own power yesterday!

Let me know if you need help again. And again thanks for giving me a hand ploping my engine back in my car.

No problem Sean, we'll get your running yet this winter/spring.

Well yesterday I put on almost 100 miles and she ran pretty good. The idle right now is between 1000-1400 rpms because when the engine is warm I can set the idle around 8-900 but when the engine is cold it is around 450-500 rpms and have to turn it back up.

I need to install another new thermostat, this one is very slow to open. Almost 3/4 full temp gauge until it opens, but once it opens it stays under half way up on the temp gauge. So either this one is shot or I installed it backwards.

This morning I had to drive it to work since I dropped off the Caddy last night to have the tranny checked out and get it fixed under warranty. So we will see how she starts and runs this afternoon after sitting out side in this cold weather. Hope it doesn’t cause any problems for me.

Its good to hear the caddy is getting fixed.

Let us know how it goes this afternoon.

Other then the CEL 52 she is running great. Yersterday did a few WOT pulls in 1st, 2nd & 3rd and pulled pretty good for having 52 and a OEM CT-26. Now if I could just get the idle (lower) to work with me, and my boost sensor would work for my gauge, it would be sweet.

Well I found the coolant leak yersterday and it is the heater return hose on the drivers side. Couldn't find the correct part # so a quick visit to flash chat and the guys there had it in like 2 mins. So I ordered another new one and this time I wont over tighten the worm clamp. It should be in today along with 12 more NGK coppers.

Also went to Toyota yersterday and picked up a new thermostat and had them cut me a new key from my vin # since the key I have is the valet key (dosen't open hach or glove box) and it works great. So any one wondering if you can still get them made the answer is YES, for $11.99.

So it looks like I will be busy tonight after work again install more parts and also taking a look at the idle and TPS to see if can adjust it better.

 

[92nsx]

Last night after work I installed the new heater hose, and what a pain in the ass that is to install with a FFIM. But a few beers, 5/16 scocket, a knuckle/wobbly (what ever you call it), a couple 6" extensions ,and 1/4" drive ratchet and it was in. Since the cooling system was drained I also installed the new thermostat.

Warmed up the engine checked for leaks and went out for another drive (and a couple donuts :evil2 put another 40 miles on it and the cooling system is 100% again. Maybe this weekend I will dig into the wiring and replace the kock sensor wires again

Damn Rob I'm kinda jealous you have a running supra.

Few more small things and she will be rocking.
