Running M44 build!

[DesktopDave]

Inspirational stuff here. You're so close! Hurry it up, I need a cheap recipe for my worn out motor!

 

Just kidding - this is a "take your time" thing that must be done right. You've made some incredible progress so far, thanks for sharing.

No choice but to take my time, since I have little to spare. Still on the to to list are: install o2 sensor bungs for the rear and wideband. Replace tps and maybe icv. The tps reads 67% @ WOT and my idle is terrible. I think that cam has a lot of duration and that is killing the idle and may be causing it to go lean at wot also. I have the cam trays and lifters for 33mm swap waiting also. For now I will just put the intake in since there is no welding required and im pretty sure thats where the noisy lifter is.

I realized thst I haven't updated his thread in a bit. As posted in engine management section, I have installed A SAFCII to tune. Its running on a shot-in-the-dark tune that is light years better than stock. In the long run I hope to log the data to provide to a flash tuner.
I'm lowering he compression this weekend with a 2.04 hg. Not the route I wanted to take but I think its for the best. Still will be 11:1. At the same time I will replace the topped valves and install the 33mm lifters and s52 beehive springs. I have at least one completely collapsed lifter and there are others noisy also. I'm hoping for even a bit more power after all this even considering the drop in cr, once everything is correct. I might even go m20 hunting 
I also edited my first post to reflect all the mods in one place.

benz-tech,

I would leave the head gasket alone. I'm not familiar with the SAFC II but if it can only do fuel then you'll have the same problem at 11:1 compression as well. So that unit is not the answer for your build. You need to be able to control timing also. You might be looking at a stand alone unit in your near future. If you want to lower compression get a bigger cam and bleed some of it off, but you will still need a proper tune.

Cheers,

It's not like it's pinging badly. Just a bit on low-rpm tip-in and only on hot days. It's nothing the the knock sensors can't handle. I just want to keep it off the jagged edge and fix a few issues while in there. Unfortunately neither a stand-alone nor 11mm cams are in the budget(although both would put it over 200 hp I'd guess) This was basically supposed to be stronger daily, but things got a bit out of hand.

I did a comp test before removing the head and got a high of 237 and a low of 215. Turns out my exh guides/seats/valves were shot. I was very broke at the time of the initial build so I had done the seats myself (based on worn guides). Now it has new guides and exh valves, and a pro did all the machine work. S32 springs (pic. Edit: now it won't load) and bridges have been mocked up and the intake side is good.  Will check the exh side too before running it as well. And more pics.

Update time. The S32 springs, buckets, with a fresh valve job, new exh valves are all in and quiet. Along with a 2mm hg. Once everything was healthy, I got Midnight Tuning's 91 Oct tune and love it.  I put a video up on IG. 320ie30 if you want to watch.

IG. What's that? Would love to have a look.

Instagram. It's a smartphone app. I forgot to mention that the road is actually up hill a bit also.
