Any change in unit cost from initial estimates?

Very very very nice... all the adjustability makes me second guess my choice of coleman racing spindles

6061 or 7075?

"Economy" Unit cost?

Not to hijack Steven's work on the front 88 hubs and if this needs a new thread for the Rears I'm happy to transfer Nevertheless we have a new LS4 / Fiero swap vendor I came across (well fb forcibly notified me) named 2P or Pickard Performance. Several products for 84-88 suspensions on top of his LS...

Does anyone have any experience installing GDI teflon seals on direct injectors? I fiddled for about 3 hours yesterday evening attempting to install even one of the two seals back onto my first GDI injector. I have the EN245 GM seal install kit but for the life of me I can't get the seals to shrink ...

it appears as though I was downvoted on the forum since that post, the arrow on my ratings bar is red now... lol!

Threw you a positive rating....cuz... facts, data, evidence.......damn...... really pfiffle?

Head studs vs Head bolts... Both heads have been pulled, cleaned, and reassembled with the 82# springs and ready to go back on the LF3 block. The TTY head bolts on the LFX/LF3/LF4 family are all the same part no. and of decent size: M11x2.0x158 10.9 grade Head Gaskets are OEM 4 layer MLS The "c...

I have custom headers that remot mount a bw efr over the tyranny..

No leaks found or heard of in forums..

Gasket is mls

Ok RFT braintrust.... regarding exhaust manifold (headers) to block fasteners.. .will there be any real gain going with ARP, stainless, or even inconel (OE mazda rotary) studs instead of the OE 10.9 bolts?

My build is currently running c6 front calipers front and rear via adapters. What is the center to center bolt pattern if the c7 brakes if you don't mind... I'm assuming the c6s will not mate to your upright. Also running Rodney's lowering ball joints. And have yet to test the Coleman spindles.. Hmmmm

Pulled heads to refresh them... I did not want to dig into the engine as i want this thing running....in for a penny.... Direct injection intake valves with only 35k miles on them... The LF3 and LF4 have a rather elaborate PCV system due to positive crankcase pressure of the turbos....however will d...

Nice... Final material?

Same ride height I assume....

Are you planning on making a run of them? If so count me in for at least one set...

Engineer interviews, etc...

Very impressed with what they did with the LT6 from an engineering perspective.

Welp..... i get to pull the head... or at least one of them.... While trying to replace the intake springs and retainers on the #6 cylinder I had to tap the keeper/spring with a rubber mallet and socket to dislodge the keepers. I lost all pressure in the cylinder as a piece of the GDI carbon buildup...

Are they actually any lighter than stock, being that much larger? Any reason (cost, I @$$ume) the new ones aren't tapered/beehived like the stock ones? They are listed as "beehive" on the website but they definitely aren't 'conical' anywhere.... They are also not lighter... the larger ret...

So called stage 1 TapOutTuning titanium retainers and springs to allow for running higher rpm under boost. My goals are only to bring the rpm redline up to 7200 under boost which is the stock LFX limit and to allow for the higher flow of the BW EFR turbine. https://sat02pap001files.storage.live.com/...

Sorry, MS onedrive mobile is misbehaving as the picture is not coming through on my end for some reason... Yes, these are the the fuel cams..Oem on left and Tapout tuning modified OEM on right... You can see where the fuel lobe has a bit deeper valley with respect to the shaft shoulder.. Supposedly ...
