My low milage turbo Prep

Just get ARP's so you don't have to worry about it trust me I wish I would have never done metric blues

[einstein57]

Metric blues on your existing head gasket will handle 300whp all day. I speak from experience. Rough rule of thumb is whp/10 = required injector size. You want to be 80% or below on the duty cycle. Everyone says 42 because you won't have to worry a out changing them out when you eventually grow tired of 250whp. Also leaves headroom for e85

From what I've read your right all I'd need to do is headgasket and apr to run low boost safely

[edsel1134]

And thanks for the insight I'll look into it tomorrow

Don't waste your money on a Cometic Headgasket. They have a tendency to leak if the block or head arent prepped right. Go ARP's with goetze head gasket. You have three lines running along the frame, fuel pressure, fuel return and EVAP. The hiss you hear is a vacuum leak from your pinched EVAP line.

Evap line could be causing the hard start.. And advice on fixing it?

I'm running the lucas 42's and have no complaints but these 60's are good too

[edsel1134]

Yeah just don't want to dump 3-5 k on a swap and then worry about s series failures lol

I'm running an NA built S52 with grey top 24 lb injectors. Everyone I know who is turboing goes 42 or 60. Im also running a 318 in-tank pump (converted from dual pump setup). Absolutely no problems at all and I'm looking at close to 300hp.

[edsel1134]

And how's the stock block safe too?

[edsel1134]

can some one snag me a link or part number for the injectors listed above? stock fuel rail?

[edsel1134]

really? thats awesome may need to replace it anyways but cheaper to go OEM when i can.. and wow 42lb? must be something with it not being a coil driven spark system..forgot what i ran on the s50/s52's but dont think they were 42

[kamotors]

Yup stock fuel pump works just fine, and you'll probably need 30lb injectors at a minumum for your goal of 250whp. might as well go 42lb or 60lb so you have room to improve.

[Good & Tight]

Stock fuel pump is good for 400hp.

TRE 255lph for the fuel pump
