Did you put too many shims in the throwout bearing? Did you measure before you installed everything?

Also, the whole driveshaft needs to move forward about a 1/4" to fully seat the tip in the bearing. To check this install the engine without the clutch and tap it foward till its fully seated. Probably not what you want to hear.
If you need to move the shaft forward, youll need to redrill the pinch bolt slot of the shaft

i didn't shim the TB. installation didn't require it due to it seats flush when installed....i didn't need to remove the original TB because it didn't even hit it when i installed it.

Also, the whole driveshaft needs to move forward about a 1/4" to fully seat the tip in the bearing. To check this install the engine without the clutch and tap it foward till its fully seated. Probably not what you want to hear.

thanks Spence,
what do you mean by rederill the pinch bolts?
are you referring to the coupler bolts?
pictures or links oh how to do this would be greatly appreciated.
thanks

It sounds like your throwout bearing is engaged when it shouldn't be

thanks Spence,
I took your advice and tapped on the shaft a little bit and clink it went in....
what a relief, I was ready to pull everything off again but from the looks of it I may not need to.
sometimes the easiest and simplest way works.
thank again..

You should really verify the depth that tip went into the PILOT bearing. If that tip isnt sitting in the bearing fully, it will destroy itself and you'll have to take everything apart anyways.

86 Porsche 944T LS1 swap begins - Page 2 Empty more test fitting

Post  smkn951 on Sat Apr 18, 2020 8:52 pm

today i went and separated the TT from the adapter from the bell housing... what a PITA....removed the clutch and ensured that the shaft is seated well into the pilot bearing.
Went ahead snugged a couple of bolts on the bell housing and adapter plate and then to the TT and mounted the transmission up.
there was a significant gap from the transmission input shaft and torque tube driveshaft.
the coupl3et would not line up with the recessed area for the bolt to be installed.
Went with Spence's tip and went and drilled, dremeled a relief spot for the bolt to be installed on the coupler.
that's it for today...next job is to tear everything down again and install the clutch and torque back everything again.

Looks like you knocked that shaft to far forward. Only the tip sits in the bearing (up to where its chamfered, look at the pictures in the other thread).

aftermarket computers dont require a vss signal to operate like the oe gm computer, so the vss kit shouldnt be needed.

86 Porsche 944T LS1 swap begins - Page 2 Empty input shaft adjusted

Post  smkn951 on Wed Apr 22, 2020 11:25 pm

a little update.
Adjusted the input shaft depth. checked the alignment of the coupler and it lined up at the original spot. thanks Spence, and sharkey for the inputs.
I did verify, while the transmission was still bolted and the coupler loose, i gently pried on the input shaft to go a bit more to the rear and marked the input shaft at the pilot bearing.
lined up the coupler and tightened it up. so far so good....
loosened it back up and separated the trans mission and dropped down. pulled the torque tube back, removed adapter plate and removed the bellhousing.
so far the belllhousing is in, adapter plate, hydraulic throwout bearing and torque tube.
input shaft was gently coerced into disc and i stopped at the spot where the coupler bolt lined up in the hole.

If you havent measured for the throwout bearing, now would be a good time to check it.

86 Porsche 944T LS1 swap begins - Page 2 Empty intake boot clearance

Post  smkn951 on Thu May 14, 2020 12:13 am

hello everyone,
what should be the distance from hood latch to throttle body?
it appears that my boot is a bit pushed in on the corner of where the hood latch is? is this ok?
oh i also did the coil pack relocation and did custom plug wire lengths.
i finally installed the brake booster and plumbed the lines. hope that i got it connected right..not sure which is the hi/lo lines are on the steering rack. crossed fingers..does any one have a picture of the back of the power steering rack with lines identified?
thanks

The hose hitting the latch is normal. It won't hurt anything. I usually trim the hose as short as possible on the throttle body side, but still will rub.

The lower fitting on your steering rack is the high pressure side.

thank you I'll go ahead and switch those hoses underneath.
as for the intake what a relief thank you. i thought the ls6 intake was the issue clearly I'm being paranoid...thank you now i can relax a bit.

86 Porsche 944T LS1 swap begins - Page 2 Empty corroded wires

Post  smkn951 on Fri May 15, 2020 11:05 pm

just a small update,
while trying to route the Holley terminator harness i ran into some corroded wires....i had to pull the dash to see the extent of it and it went all the way to the fuse box. spent good part of the day replacing wires but its all good now. luckily there are no other messed up wires.

have a good day everyone.[You must be registered and logged in to see this link.]

Very common problem on 944's. That's the blower fan resistors. They build up a lot of heat and basically cook off the wire insulation over time. I've seen those start fires inside the dash.

got in the fuel rail and regulator, now just waiting on the rest of the fitting to do the fuel line from the wheel well and find a more suitable spot for the FPR. also waiting on at fitting that has provisions for a fuel pressure transducer.
slow but definitely chipping at it.

86 Porsche 944T LS1 swap begins - Page 2 Empty how long can it run without coolant?

Post  smkn951 on Sat May 30, 2020 7:31 pm

hello everyone,
well i managed to hook up the holley terminator x. very easy. fired up on the first try. i was really surprised that this ran without blowing up or seizing.
i only ran it for less than 20 seconds i hope i didn't mess up anything.
i still have coolant to do, bolt up the transmission, bleed the clutch. install the belts, test the steering and hydroboost, install the rest of the dash and find room for the gauges. install new interior upholstery and of course the A/C.

a short video, im happy it runs.......for now. it's been down for a rear main seal. got it replaced and seems to be doing ok at the momnet.
still need to get the dash gauges to work ie oil pressure, temp , voltage(need to be regulated, current; charging at 14.9v, and tach needs to be wired up.
