Posted October 6, 200618 yr comment_184928 Question: How do you maximize rwHP with an L28ET?Current Setup:72 240z with a 77 L28 with 240 carbs, header and HEI ingnition mod. It runs through standard clutch to a 5 speed tranny and into and a 4.11 diff (3.32, 3.54, 3.9 and 4.11 also available).Also Owned:'83 L28ET (complete) with 68k miles that ran smooth when removed. A 10 lb. Fidanza flywheel and A.C.T.performance clutch is already installed on the engine. A Garret T3/04E with 60 trim and .63 a/r with the HPC coated turbine housing is still in the box. So is the S.D.S EM4.To make this setup work, an old post says that I need the following:- Intercooler - Boost controller- 3" exhuast (Can I use dual exhaust?)- Bigger injectors- 60mm throttle body- Powerful fuel pump from WalbroIs this true? Can anyone think of anything else we need to make this pump more HP? What is the weak-link? Can the 77 5 speed tranny handle it? Which diff should I use for improved 0-60 time? Any guesses what the 1/4 mile time might be with this setup (assuming it works?)thanks for the help!

October 8, 200618 yr comment_185109 with some 440cc injectors you should be good for around 400rwhp!0-60 time no idea1/4 mile time.. easily a 12 sec car.. 11's with drags or slicks 400rwhp at about 19-21psi with ur T3/T04e I think you have a buyer as of today at the ZCCC track meet.. some guy was talkn to me about your setup and if it was good Austin with SDS and a T3/T04 ran a 12.2 at 125mph at 19psi on street tires.. and Ted ran a 11.4 at 20psi on slicks so yes this engine is very quick im running the stock fuel pump.. and look at the list of mods i have.. i prob have around 350rwhp .. its fun =) Link to comment https://www.classiczcars.com/forums/topic/21831-how-do-you-max-hp-with-an-l28et-and-garret-t304e/#findComment-185109 Share on other sites More sharing options...
