It’s been a while since I’ve read on this thread. I wish I was # 23 ! Wish the thread did see more action as well as the site . I’m so tired of the FB shit

Ordered some cheaply sponge filters while I wait for my CAI box to get finished . Made a smaller vacuum log -3/4” PVC pipe . Despite having one of my widebands flaking on me I was able to drive around well enough that I wasn’t scared of dying on the road anywhere . Not much help out there for guys running MS and ITBS. Seems most Haltech or others . I’ve also got different perspectives on how to load certain tables . I have Yanni saying that all the tables can be run off of TPS and Richard that says running timing off of MAP is best . Presently I am going to try and run it all TPS . I can only hope the FAJS version of a TPS is accurate and reliable . I might eventually go with a contactless style from EFI hardware . For now I haven’t gotten past 38% TPS on my tuning so I’m not stressing my TPS to hard that’s for sure . Honestly - I didn’t think it would run even this good this early in the tune . I am trying to be patient with throttle input since I do hit big lean spots . I am also learning how to use Megalog Viewer at the same time that has a VE analyzer which is pretty damn cool .

Drove around yesterday with heat shield on . The tune is pretty rough and and sometimes the car wanted to die from starvation -scary . I used timing to lower idle after reading about a trick to deal with hit idle . Might have to call on Richard to help me remotely . Lots of rain right now so driving time is scarce .

Reducing vacuum line size seems to have helped the MAP reading. Looks like I might even get 60kpa at idle too! First drive was interesting for sure. Almost stalled pulling out in traffic and rich and lean mixtures all over the table-lol. The autotune was trying to correct but some of my settings were off. I didnt stay out long because it was Little 5 in Bloomington and too many crazy kids out . Monday when everyone is at work Ill do some more tuning, Idle seemed to increase as the engine got hotter. No heat shield yet so that is an issue

Latest version of mock up for test flight . It started up easy and just idled nicely - I was in shock - lol. MAP readings was around 65kpa at idle which isn’t much different than the plenum idled at . Reading was jumpy so I talked with Richard and dropped the vacuum like size from .250 to .125 - which should help smooth out the reading . Big cam and all it just idled and blipped ! Wont have the my CAI done for a minute so I’m going to run open stacks until my foamies come in . I won’t run it long like that but to get a base tune down . Murdered out my vacuum log so it would be so obtrusive .

Good news is my exhaust collector is ready for pick up ! Bolt this thing up and ready to fire . Reached out to Chickenman- Richard Boyk - who said he’s done tuning with ITBS before has set me up a base tune . Can say enough how helpful this is since Alpha N is all new to me .

ITBS are bolted down after doing some fitting of the Maxima Diesel intake . Still waiting on the welder to finish up my collector pipe so I can’t start it yet . Also need to finalize location of vacuum log that will be inside my CAI - whenever it gets done at the welder . I wish I could TIG worth a shit and my life would be easier - lol. Still most of the back breaking work of bolting this down and plumbing should be good to go .

New exhaust for the 3.2 ! Serious drone issues from failing resonators made me go to a single thru the resonator . This resonator has a J pipe to help with the HZ 110 I had at 2200 rpm . With my tall OD this was an issue. I went with Borlas out back as big as I can fit so in the end I’m hoping for a quieter exhaust and less drone .

Did more work in the ITBS . I’m mocking stuff for test runs to see what might work and what might not . Goal is a decent MAP signal up to 30% throttle and be able to run brake booster and PCV . I thought the PVC would work for the PCV - lol. Just all temporary fun. The base plate will be trimmed down to about 6” . Running 1/4” vacuum lines to this 1” log . It might be a bit big but I want it to do a lot Final iteration might be 2 vacuum logs . Maybe ready to fire in a week or so

Well as I change my induction I am also changing the exhaust . I am trying to quiet down the exhaust and also reducing drone I have around 2k . I had cheap resonators on there before and they were making more drone than preventing it I believe . I decided on a single resonator with a J tube targeting the frequency of the drone . It’s a 123 resonator I found on eBay . SS everything including packing . So now my exhaust is 6-2-1-2 ! I also got new mufflers for the rear . Added larger Borlas to replace my Magnaflows . Keeping my fingers crossed that I my choices produces the right results . I will still run two widebands - one for each bank . I was able to tuck this exhaust tighter with the single resonator . I also did all SS this time which is a first . MIG welded most of it and had the collector TIG welded to assure of no leaks . V banded for quick removal

local dealer here told me that they were no longer available

Looks like those might be it but no sizes are listed . I have not heard of this vendor before.

Okay - you would think they are the same . Were you able to specify sizes ?

I am trying to find a source for shims that fit under the rear bearing . I want to change the depth of the pinion but can’t seem to find shims .

The info is in the guys computer but I’ve never seen the results of my porting

You’ll probably have to remove any “ear” casting at the bottom of the case to help fit between LCA and diff . I don’t have to cross behind so I can’t help you there

Well things changed a little . Bought some FAJS 45’s to put on the 3.2. I’ve tuned triple Mikunis using Megasquirt to control the ignition . I figured I get ignition sorted first and then go EFI . While the diesel Intake is going thru its R&D I wanted to make sure I had something to drive and I sold the Protunerz . Always looking for helpful tips for tuning - even basic linkage reminders - it’s been a minute . I opted for the cable linkage though my Harada intake cam with rod linkage . I plan on trying to make cable work because it was brilliant on the single TB .

Just a thought but you will find small cracks sometimes on the nose between the valves which might be more cosmetic than anything else and can be welded . I’d see what the machine shop says

What year head ? Where are the cracks ?

Adapters for Subbie diffs are still plenty available . That’s not the cheapest but easiest option - plug and play . 3.54 is the most common but there are 3.9 clutch types around .

Time to modify over the winter . On the list is to quiet down the exhaust and try and get rid of all my drone issues . Also on the list is make another intake manifold based off of the diesel intake . Currently at the welder for the first step in the process . I am flipping around the plenum part of the intake to ‘uncurl’ the intake away from the engine . This gives much more room for the fuel rail and injectors . Also provides straighter shot to my CAI . I also plan on increasing plenum size for more volume . I noticed with the Protunerz and its 38mm runners that I lost a lot of torque down low . The diesel intake runners are an ideal size to match my ports in the head . Longer runners should also help . It will be interesting to see how the engine performs with this intake

SOLD

What year Z ? what trans crossmember ? Is the crossmember the early or late ? If the crossmember ( late ) is put in upside down that would lower the rear of the trans and raise the front of the engine .

Not mounted in stock location though- right?

So with his kit you have to run a 5mm spacer which I don’t have room for . I don’t remember reading about that with the kit offered here .
