TTA fuel return line

[LSTTYPE]

Can anyone tell me if the fuel return line on a tta is bigger diameter than a turbo buick return line. It looks looks like it is the same size as the feed line. I threw my old factory one away on my Ttype and went with a 6an line. Trying to avoid using a 6an line when I convert to e85. Thanks in advance

curious why not use the -6an?

 

[LSTTYPE]

I used the 6 an on my t type no brainer there but the tta line looks a tad bigger in diameter and the bends aren't as sharp. I'm hoping it will flow enough to not require the 6 an line and retain a more stock look.

gotcha, what exhaust do you have? i'm thinking of getting the hooker kit when i install the new downpipes.

 

[LSTTYPE]

Well I'm super excited. New downpipe on the way thanks to you! New precision billet 6262 and all my E 85 stuff coming shortly. Got a 911 converter for it. It has a 3 inch single shot cat back system on it but I'm gonna take it off and throw it away. Kinda cobbled up. I want a nice stainless cat back system for it with the ability to put the factory exhaust tips back on.

 

[Instro84]

what stainless exhaust you gonna get the magnaflow?

 

[LSTTYPE]

Haven't gotten that far yet. Does pypes make one?

 

[Instro84]

not sure, i'm thinking of getting the hooker one the price isn't bad and using my stock tailpipes. i want to wait till i get a fuel pump and exhaust and do al that stuff at the same time.

The TTA main fuel is 3/8 and the return is 5/16". i am pretty sure that is the same as a GN. With proper volume, they are good for 550 HP on regular gasoline.

Thank you for the info. I'm gonna try a deatchwerks 300 and see hoe the fuel pressure controls.

i saw on the tat board you're going with a 4 in cold air kit, looks like you're making a lot of changes. don't forget for that big of an intake you'll need a angle adapter for iac it also interfered a little with the up pipe on my buick its bigger than stock.

 

[LSTTYPE]

Why do you need an angle adapter? I know my buddies use 3.5 and 4 inch maf pipes and don't have angle adapters. Hmmm. Do you have pics of your 4 inch set up?

 

[Instro84]

ill see if i can dig one up intake is off car now but on my car with a turbo with a 4 inch inlet it hit the pipe with the iac going straight out

 

[Instro84]

shoot me your number and ill text you a pic of what it looks like paying no there, buick is apart right now but i can lay the pip in place so you can get an idea of the clearance

 

[LSTTYPE]

785 806 2331 is my number. I mocked mine up as well. We can compar pics

I drilled out all of the Saginaw fittings, and with both pumps running I can get the fuel pressure under 30 psi.

 

[LSTTYPE]

I would put money on the tta return line out flowing the GN return line. It has smoother bends etc.

I use a 3" maf pipe on mine, and it barely clears.
