Started getting everything ready for the trip to the machine shop and snapped a few pictures.

Forgot I had this... Bolts to the starter holes and holds the flywheel for engine assembly.


Part number if anyone wants one. I cant remember what I paid, but it was either 12 or 22 bucks on ebay


Quick snap while I can



That oem ringland tho!




I got the TB pigtail this week, and i got the pulley boys tensioner tool from a buddy today too as well

 

Ok i think i got some matching spacers that will work out perfectly, gonna test fit them against the bolts to see how they do, got much more precise fitments using inches instead of MM. Should be here by monday so we will know something. If it works out well ill order the M6 extended bolts in exactly the same size as what ZZP gives with their kit.

 

Why the 13mmo od spacers if the phenolic won't bore out that big?

And why only 3/8 long for the other ones? I would have gotten some a bit longer

 

cant run one spacer for both, have to run two separate spacers, gonna see if i can install the adjustable ones into the phenolic spacer and have it align the gasket and spacer properly on the thread of the M6 bolts, and then see if it aligns properly with the spacers pressed into the manifold (which i can bore to 1/2 (.511 = 13mm) and hopefully....it all matches up properly using the M6 bolt as the guide rod. Spacers had to be a hair longer on the phenolic because they need something to support the gasket. Worst case scenario I wind up going with a nylon or rubber version for the phenolic spacer, have to keep both gaskets aligned perfectly without preventing it from sealing when its crushed against the manifold. All just theory at this point.

Trying to make both holes match the M6 bolt, in the same way that ZZP made the phenolic mounting holes match the thickness of the included M8 bolts.

 

On the braided clutch line from a while ago I believe OTTP makes them as well, but the ones from Dezod are nice and he's a good guy.

 

Ordered a new 2.5 bar tmap, and the pigtail today. sensor was 30 from amazon. pigtail was 28 shipped.

I think I'm going to order a TOB and clutch line today. After that I think the only thing left that I need is the clutch/flywheel

 

What are you going with, OEM flywheel and what clutch?

 

Spec flywheel and stage3+ clutch

The oem flywheel is not like the oem in the f35 cars. It's a different material and doesn't like very aggressive clutch disks. They wear prematurely

 

Dont order the TOB I have a brand new one sitting in my room

 

gm part or a repop?

 

Double check that part number to make sure its the right one

 

that looks like it. pm me what you want for it.

Also, my headgasket and return fuel system showed up today. Still trying to figure out how this thing hooks up. I understand how the return style works, but with the parts supplied, I'm having a hard time seeing how it is meant to go together.

I wanted to double check the "whats in the box", but the site is down

 

I ordered it too, did you get a LSJ fuel rail yet?

 

any particular reason to swap rails?

 

for the return system. Ours doesnt have the quick swap end that makes the return line easy. plus ours feeds on the cyl 4 side, and would need to exit at the cyl 1 side. the fuel line would neet to wrap back around either the front or back of the engine.

the lsj rail feeds on cyl1 and will exit cyl 4

 

Yeh but, why do you want to swap to a return style system?

 

with my power goals the factory system gets fussy. not sure on the details, but it seems unanimous that it's the way to go for high power builds

 

I have mixed feelings about it, anything under 500hp, I see no reason for it. Only in extreme cases where your running a high flow pump with big injectors and you need that volume and steady regulated pressure, like with high hp E85 builds, do I feel its a necessary conversion. Under 500hp on pump gas, or stock fuel pump, let the ECU do the work. I find the returnless system to be remarkably pain free when it comes to tuning as well.

 

I am going to be e85, id1000's, and aem320

plus pulling nitrous off the rail.

keep in mind I plan to run the tvs on a 2.6 and ati (so ~2.5)

it seems that people run into fueling issues way before then on e85

 

Could you do a writeup on the rsfs install? And did you order it with the fuel pump rewire kit?

 

It wont be going in until it's warmer, but sure. After holding all the parts in my hand, it makes sense how it all hooks up.

 

lol fair enough then, makes sense to upgrade the fuel system with that much feeding off one rail.

 

i have the fuel pump rewire kit already, made a HUGE difference. Was seeing up to -10 on my LTFT's after the switch, had to rescale my entire maf table.

 

I have been reading up on fuel systems and tuning, and am starting to stress out over my lack of tuning knowledge.

On their brfs page, Zzp says that the lsj ecu stops compensating fuel at 17psi, and the 2.4s stop at 12 psi, and that's why they run boost reference to automatically add fuel pressure resulting in more fuel.

Reading up on the setups, it looks like the zzp brfs and the ottp rsfs are basically the same concept. The fuel Lab regulator has a nipple to increase pressure with boost 1:1 as well as the one that comes with zz kit.

So basically if I leave the nipple unhooked it will keep constant pressure, but if i hook it up it will increase with boost? Is that what people mean by "base pressure"? The pressure at idle because it will go up with boost?

What are the limits of the e37 in terms of boost? Spawn, you seem to have a pretty solid understanding of tuning

Haha my knowledge of tuning is essentially zero. I have a good understanding of the mechanical aspect of everything, but the tuning is where I have zero experience haha.

 

just did some more research and verified that I am, in fact, completely ignorant when it comes to fueling/tuning.

it raises 1:1 to make up for the boost pushing back on the injector. so the fuel pressure rises 1psi per 1psi of boost to keep the differential constant under boost. derp. makes so much sense now.

I think I just found out what I'm going to use the oem nipple on the manifold for...
