Thanks, it helped to verify that the 22" shaft is correct length. I did finally figure out what was wrong. The plug on the inside of the inner tripoid joint was out of position. It was too far out which was stopping the joint from sliding all the way over the retaining ring. When you...

Thanks,

Had the car for about six years. Almost everything was rebuilt replace the first two years. Car makes over 400 hp and 380 ftlbs on the dyno.Transfer case was not rebuilt during the initial rebuild and started making noise. Pulled transfer case out and rebuilt it, at that time the...

UPDATE:No one ever commented on my data log after numerous requests for me to post one.Took the car out of storage and took it to a different, well known shop that is local and had them verify.It is NOT the clutch slipping. It is the BOV leaking which reduced engine power when it started...

GST here is a log I did this morning. Had to wait for the car to warm up. It is 20 degrees outside.This is my first time posting a log. Let me know if I did it wrong or if it doesn't display. All feeback on the log appreciated.

LOL, wouldn't that be nice! Or maybe it was the, "this is horrible, I'm outta here" kind of bad. :)I built the car shooting for 400 flywheel hp figuring that was about as far as I could go and keep my wife happy with the street manners and reliability. It looks like I'm on track for that...

"Lastly, make sure you're present for the dyno session next time. Like you said, hindsight is 20/20, so hopefully you're realizing at this point that all this guess work is something that can be avoided in the future. Regardless of the shop or their reputation, nobody gives a sh** about your car...

My "demeanor" is fine. If you can't take it, don't dish it out. Period.I asked very specific questions that nobody really has an answer for. And that's fine. But something that was brought up was to data log my tune and report back. Which I said I would do. I'm concerned about the AFR...

No, I paid full price for the dyno tuning.

I'm not blaming anyone. I wish they had called me and I would have told them to run it again on the dyno at higher RPM. BUT, hindsight is always 20/20 and I understand what your saying. The gradients for the AFR are tough to figure out on the chart. The bottom of the chart states that AFR...

I agree that's a good idea. I'll try and get one in the next few days. Besides RPM, MAF and Map and TPS what other things do you think would be relevant without too much data?

Oooh Boy, I love it when someone thinks their getting the spoon out! Now it gets fun.Your numbers above.1. It slipped at 3850 rpm. If your worried about destruction, that's where you stop. Not at 5k. But nice of you to decide what others are doing for them. 2. Why do another pull...

They did not provide a log of the run and they did no tuning on the car. I did a boost leak test before I took it down and they did a boost leak test before they put it on the dyno. I did do a long pull up a hill before I loaded it on the trailer to bring it home and a couple of quick hard...

Dyno chart with of a car with proven clutch slippage. AFR did not change at all during the clutch slipping.

That is a possibility, but how do we prove that? I don't make repairs based on guesses. Everything needs to line up and be understood before you can make the appropriate repairs. Otherwise its just guessing with possibly no results. I.e. how does a clutch slip at 3800 rpm at 20lbs boost and...

it slips at 20 lbs of boost but grabs at 24 lbs of boost.....? Rpm is engine RPM and not roller rpm. Did not hit rev limiter. If they let of the throttle that would be causation and not symptomatic.Besides not understanding how it's grabbing and climbing at 45 and 60 degree angles under 24...

Because?That doesn't explain any of my questions....

Double Din fits without any problem. Need to use the factory radio brackets to mount, there is no aftermarket kit for it because they all say that it won't fit. It will and does all the time. If you can't find the factory radio mounts then you will have to make your own.

I thought about that but 1) if the clutch started grabbing, why stop the dyno pull? 2) Why would you only do one pull? 3) How does a clutch slipping change afr (it got leaner at that time on graph) 4) Would Boost stay the same with a slipping clutch?

Took my wife's 97 eclipse in for an actual tune at a performance shop on a dyno for the first time. All previous tuning had been done by me as I figured out how to manipulate the ecmlink software.Tuning shop made one run one on the dyno and said that the clutch is slipping. Never had a...

Finally an intelligent life on here!!! Gsxeclipse102 Glad you exist LOL. To answer your comment, about the brake booster your correct, most cars do have a check valve in there, but its more so that the booster doesn't lose it's vacuum under boost conditions for a turbvo car and even a na car...

WOW, waffle much?This was posted earlier by someone else: " even with the wastegate tied fully open it'll still have flow past the turbine wheel allowing boost to build "Sounds exactly like what I said is wrong and exactly what you just said no one said.Now it's not building boost, but...

"As far as turning off the turbo in link, he's right. It doesn't work like that. You are limited to the minimum amount of pressure your wastegate spring is rated at. An MHI wastegate spring is 7-8PSI for a 14b/16g setup. You can turn the duty cycle to zero in link, you can loop the wastegate...

Worse part is that we supplied the valve seals to the machine shop since they were included in the head gasket kit. :(

Pulled exhaust manifold. I have oil sitting on the exhaust ports of cylinders one and four, cylinder 3 shows signs of oil and #2 is def dry. There is oil in the manifold as well. Time to contact the machine shop.Matt

I used a gasket at the bottom of the drain with the Right Stuff on the bolt threads to seal off bleed through from inside the pan.

Shouldn't I see wetness at the center shaft of the turbine wheel? And since the exhaust valves feed the exhaust through the turbine wheel, how do I know that the oil isn't from the valve seals and the spinning of the turbine isn't throwing it to the outside edge of the cartridge/housing?

I'd agree, but it didn't smoke before the rebuild. Course I may just get frustrated enough to try it and see if it "heals itself" lolI just did a classic example of what sounds good is very different than what works.I pulled the O2 sensor housing as suggested by several to inspect and see...

Tube is straight and clean. It was replaced when the turbo was and re-verified good during the rebuild while the motor was out and the head was off.

Oh boy, start your own post, and post a video of your car building 20 psi in neutral.Then I'll post my video of my car revving with no boost on the boost gauge and I'll then video the boost gauge feed line to the intake so you can see its hooked up and I'll even video the settings for you...

This is diverging off of the topic. Put a pressure sensor on the intake and measure boost directly with revving in neutral. You won't build any boost. Turbo will spin at a lower rpm, yes, but it won't boost.The sentence in front of your icon does not convey to me what you say it does to...

You confuse turn off boost with spinning. Boost can indeed be turned off in link. It has the aftermarket waste gate solenoid that is duty cycled to allow it to create boost (or not). If the waste gate stays open, there is no boost. This happens all the time. Rev your car up in neutral as...

Little more background.I'm an ASE certified master Mechanic with 26 years experience.Head was sent out to the same machine shop that I have sent all our shop heads out to including a cummins diesel head. I have never had a problem with their work before.We purchased a Felpro head gasket...

late update but an fyi that may help others. An O2 sensor will never cause a stumble or stall at full throttle. At full throttle the ecm no longer uses the 02 sensor for fuel control. The system instead runs off of the internal fuel control maps in the ecm/pcm and dumps extra fuel according...

Have a 97 eclipse GSX that we've been completely redoing/updating.Almost all done, but there is smoke out of the exhaust, rpm related, worse when driving but can do it in neutral as well.I have the ECM link system and I have turned the turbo controls off while I'm dealing with this. Have...

Back to the basics. Do you know what your engine vacuum is while the engine is running at idle? If I were to guess, I would guess that your car accelerates very poorly off of idle and builds up speed after the rpms come up.My guess is that you are off one tooth on a camshaft. You can't be...

What are the differences in seat cushion size and or shape when comparing the three seats?I can't find a good GS or GST seat to compare to a GSX. I know the GSX has power driver seat, but are the rest of the cushions the same size and just the covering material is different? Or are there...

Too funny. I'm putting together one that I purchased in pieces and that plug was disconnected on mine as well.

What is the normal response time to get an answer to an email?

I sent two emails on Monday and Tuesday thru the contact form and haven't received a response either.

Just looked at the production dates of the two cars. Nov 1996 and May 1997 Both vins for both cars are 10th digit V which identifies them as 97's.

To Pauleyman..... The original head on the "old" 97 had no sensor on the passenger side of the car and I've checked the wiring harness extensively over the last two days as I've worked to figure this out and the harness has not been modified in any way and there is no sensor on the pass side...

I can get the production dates off of both cars tomorrow. Im looking very seriously at doing the 1g swap as a permanent fix.I was going to have a machine shop here in town do the tune once its ready since they already have the equipment to reflash the pcm(or so they say - havent actually...

I'd agree with you except that the "old" eclipse is a 97 id'd by vin and and the engine wiring harness is unmodified. The "new" eclipse is a 97 as well and id'd by vin and it has the pass side cam sensor connector. Old eclipse has the connectors on the drivers side. Firing order was not...

End result and very pleased with it. These are airbrushed on.

Called them. Thier GS series will not fit the GSX, thier pattern will not work. Partly because of the power seat on the driver side. Thanks for the suggestion though.
