Please help.....
 

I am putting together an order and want to make sure I don't forget anything I may need. Please look over my list and tell me what I am missing or if you have advice I am all ears, errrr eyes!

For my exhaust I have the Magnaflow 12589:brain: but am not sure what cat or resonator I should use. I want as quiet as possible. Also, is there a known list of needed bends to order for fabbing up my exhaust (NB) or is it just poke n hope? I think I have the down pipe figured out but not sure how much of what to order to make the rest.

What fittings are needed for a 94 block so get the oil and coolant lines form the pre tapped bosses? I have seen these before when searching but can't seem to find them again. Is there a preferred type of line to use?

I want to use Braided SS fuel line that is E85 friendly but am not sure which is and what isn't?

Are all silicone couplers created equal? If not, what is preferred?

Is -10AN fitting enough for the pcv system or should I go -12? I know Soviet uses -10, what are other using? Do I need to vent both sides of the VC or just one?

If I am looking to get 370whp what size air filter do I need, what is the go to filter? (yeah I have not searched for this one but since I am asking questions figure I will include it as well).

Thank you in advance!

Just re read the sticky for noobs and found the information about the oil feed line, M10x1.5 to -4AN. Thank you Brain!

Garrett has a technical paper on sizing air filters, it should come up in google as a pdf. I like AEM dry flow, but their filter size selection is a lot more limited than K&N.

If the company selling the line says its ethanol compatible then it is, some places might not list it as such. Do remember the E is corrosive to aluminum, but only if it sits on it for a while. For piece of mind I'd use steel fittings here, a couple extra ounces wont kill you but an under hood fire might.

We ended up using a bunch of funny bends, almost pie cuts but taken out of a single U bend on the Al exhaust car, but a lot of it was because we were trying to cram 3 HUGE mufflers under the car.

The issue isn't in the fittings - most aluminum fittings are anodized, and ano'd aluminum is E85 compatible. The issue is in the hose - nobody I know of makes an E85-approved rubber-internal SS braided hose. The only one is Aeroquip's PTFE Teflon hose, and it requires matching fittings which only come in stainless steel.

Bottom line, if you're doing an E85 system, you want PTFE from the tank to the engine bay.

Sav, how many feet will that require? I an really on the fence about E85 so I may just stick with pump gas......

When I'm plumbing fuel systems I never run braided hose all the way from the tank to the front of the car; its too easily snagged, crushed or damaged. Instead I use short sections of braided line at the tank and at the rail and bend up steel hard line (3/8 inch for 6AN, or 1/2 for 8AN) for the bulk of the system. (The same holds true for connecting any in-line parts, like fuel filters and external pumps; just a short section of braided for flexibility.) All you need is a 37 degree flaring tool and the appropriately sized AN sleeves and nuts to connect to your braided lines using AN male-male union fittings. At the rail I usually use a special union which also has an 1/8 NPT hole to connect a fuel pressure gauge. Much safer than using braided hose all the way, and a much neater looking installation.
