more horsepower for my stroker please
hey, i have a 78 280z with a couple month old engine. Its bored out to 3.1L, new cam, pistons, crank, head,.....all new. I recently took it out to the track and was expecting much more then what i got. Im a little straped for cash now so i was wondering what people think i should add for the most horsepower. Ive heard many things such as rising rate fule pressure regulater, electric water pump(which would only add a few) and ovcourse NOS, but i rather not mess with that so any suggestions would be great.

if you did that build right...go get some megasquirt and TUNE IT....ppl dont think about tunes but y dump thousands in and not spend another couple hundred on a tune so it doesnt blow....if you did it right and put some money into it you should be around 250+ rwhp and around 300+ at the crank and thats plenty in that car....till u go turbo=the right way
|
I agree, but I do give him credit though. Because yes I do want to turbo my '82 280zx. But I still would like to have a n/a that is stroked. (Just not sure if it will be my '81 or '82 slicktop) Because I would have the best of both. To each his own though. Good luck with your stroker Z. And I am sure you will figure out. And get what you think, will work best for what you want.

I heard that going to 3.1 doesn't do that much more. You have only increased the displacement by 10%. So bigger on everything else too. It's still breathing in and out of the same holes. Megasquirtnspark!

Are you still running the 78' EFI?

likesaid....standalone system....and a tune + HEADWORK.....cam,angle job, valves, springs, all the rest of the stuff otherwise like he said all youve done is bore.....and maybe mill the head while youre at it if you didnt stroke it you should have upped the comp ratio with a higher set of pistons...did you do that or not?
|
headwork, MS, injectors and nitrous.
|
nitrous is crap. i wouldnt, thats a muscle car thing or a turbo car thing when trying to defeat turbo lag. u could always cheap out and go carb setup on the stroker. or ITB's :D
|
no this is a complete list of what i did to the engine here it is
big bore kit p90 heads 3 angle valve job stage 3 performance cam set f54 l28 block 89mm flat top pistons 240z rods ld28 maxima crank comprtition head gasket new bearings new gasket set new oil pump new water pump new timing chin set coated 3-2-1 header new injectors performance flywheel inlarged throttle body and a cold air intake |
We'll try this again... :D

well i was expecting faster then 16.7 in the 1/4. part of that might be my shifting but that around stock speed. and no i havent dyno'd
|
16.7?!?!?! buwahaha! that is absolutley terrible. i think it could do better stock! thats definatly the price you pay for using stock EFI for a 2.8 low compression motor on a high compression 3.1 liter motor thats for sure. part of that is using the stock injectors im sure.
|
yea im looking at an aftermarket efi but im not sure which one to pick there are so many
|
What is your hp goal? What is your price range? How did you get this far into your stroker motor w/o considering fuel injection upgrades????!?!?!
|
wow thats pretty bad, get a standalone setup but u should get a wideband and see what your afr is at.
