Thank you! That's a major load off.

ETA - 4 WEEKS TOPS. I'm pumped.

... would be less time, but my buddy is going away on holidays for a couple weeks and my car/engine are at HIS shop...

Any one here doing the 3SGE into a St204 use the S54 transmission from the 3SGE?

What pressure plate, flywheel, and friction disc did you use?

I used a 3SGTE flywheel and a clutch kit for a 3SGTE and I had no problems getting the splines lined up and the bell housing attached.

Did I do something wrong? I was recently told that I should have had to use a friction disc from a 5S as the splines weren't meant to match up... ???

the E series trans and S series trans have different sized input shafts and spline counts.

kaos show us a picture of the transmission its most likely an e series if the 3sgte clutch kit fit.

Check out my build thread, the last few posts have the pictures in them.

Actually here:

thats an s54, how did u manage to put a 3sgte clutch on that? did u use a clutch alignment tool? when u bolted the pressure plate onto the clutch/flywheel, and u put the trans in gear when ur installing it to insure te shaft goes on correctly?

How can you tell for sure that's a S54?

Used the clutch alignment tool that came in the box. Centered no problem, didn't try to put it in gear though... could try that now that the shift cables, etc have been reconnected.

Have to drop the transmission out now and put in the 5S friction disc. :'(

its not so hard, im still curious how u managed to put a 3sgte clutch in there lol? if u have a spare 3sgte clutch maybe ill buy it to test if it works for the E56

Now I have a spare pressure plate from a 5SFE and a friction disc from a 3SGTE (21 spline).

Anyone have any vacuum diagrams that they could throw up quick for me?

Still having issues with the swap.

Car starts, and idles great. Very smooth. But at 3k RPM it sputters, misfires and backfires.

Timing is good, 10 degrees with check connector bridged. Firing order correct - spark plug wires are all good. If you unplug each one of the wires it definitely changes the way the engine runs, so it is idling on all 4 cylinders. We had to take the timing belt off to deal with an oil leak, and it had the same misfire before and after. I triple checked the cam timing when the belt went back on.

No codes, even when I try the diagnostic mode. the CEL will flash when it misfires and hits this weird 2500 - 3000 RPM rev 'limit' but no codes are thrown. It will drive the wheels in 5th (car is on a hoist) so it runs fine under load, but has the same stumble/rev limit at 2500/3000.

Also loud backfiring out the exhaust, and the intake vacuum 'pulses' to atmospheric when it hits this rev limit. Plug gaps are fine but plugs are a little black. Seems like an ignition problem? Has new plugs, cap and rotor. Was going to try an igniter/coil assy from a known working ST205, also different plug wires. We also have another ECU to check with.

It runs beautifully right up until you hit this weird rev limit/misfire point. Starts right up, idles nice and smooth.

Any other ideas?

Going to try my other spark plug wires and my MR2 ECU on Monday.

Checked the TPS sensor, coil, and ignitor - all good. 90% of the parts are brand new.

I have a feeling about the wires, as I recall feeling a significant break in the #4 cable, but didn't really think anything of it when I installed it. I also want to check my vacuum lines because the ACIS is exhibiting an odd behaviour too ( I think )... and my fuel pressure VSV broke when putting the engine back into the bay. Snapped a nipple off in the hose.

In my past experience, low rev limit was came from you use wrong part no. of ignitor.

use 5s igniter and coil. ad map sensor they r the same just to test it.

>

My 5s didn't have a coil... just the ignitor.

my bad i meant just the igniter

My thoughts are on the igniter being faulty, what is your vacuum piping set up btw, some people can get some lines mixed up too

We took a known working igniter and coil and had the same result.

I'm leaning more towards the spark plug wires or the distributor.

Whats the spark like?

seems ok on startup, pulled each plug out during idle and the plugs are firing, but havent tested under load, which is when the backfiring happens...

Bout to install new Red top Beams . Engine comes with harness and ecu. But does not come with air intake hose or air box or MAF. Can I use the air intake hose and air box off of my existing 5SFE ? I plan to purchase new MAF

>
The BEAMS has a much larger throttle body and totally different intake lid than the 5S, and the MAF housing is built into the lid of the airbox so unfortunately none of the 5S stuff will work. The bottom half of the 5S intake box is the same so that part can be used again but you'll still want a BEAMS intake lid and elbow.
