Hey gents, got a question for ya. Drive a 95 z28 A4 and I have two goals for it. 1) Make 400 hp at the wheels 2) run 11.anything in the 1/4. What Im putting into the car is LE2 H/C, new lifters, pushrods, R.As, ported intake w/ 58mm TB, LTs to ORY to SLP LMs, CAI, a 3600 stall, and 3.73s on the stock 10 bolt with the axles welded together and SFC as well as STBs to help stablize everything and of course the tune when everything is done. You think Ill be able to to meet my two goals or will I come up shy? All help is appreciated.

 

You'll most likely meet your goals with that set up. you might want to spend more time on the rear suspension to plant that power....

 

Hopefully there's larger injectors somewhere on your list.

 

drag radials and some skinnies and maybe a in-tank pump to help feed the larger injectors for the added HP.

 

Okay, I may know a little but Im still pretty much rook status when it come to engine building. For those saying upgrade the injectors, what do you think would suffice 30-36# and what is an in-tank pump(its a fuel pump in the tank right?)

 

36 #/HR injectors will handle in excess of 500HP at the flywheel. A set of 32's are good for 450HP. You might get by with 32's but I'd recommend the 36's. No downside to going a bit larger. Tuner has to know what injectors you are using.

Yes. Stock fuel pump is in the tank. A 255 LPH replacement pump will help you avoid running low on fuel pressure at max HP.
