OP
Yea 12.5 NA on pump gas is doable with no timing. Retarding timing is stupid. You can make more power by lowering the comp to reasonable levels and throwing more boost in with more timing. You even say you plan to run 8.5:1 on your next build. I thats where I would run at to be safe on the street. I daily beat everything that I build.That's why it's your opinion. With a competent tuner it's not a problem at all.
You can run good ole 93 pump to about 12.5:1 C/R but don't expect a bunch of timing in the tune. We've pulled 30ish lbs of boost on 10:1 C/R with out a problem, but that's on E85.
I'll be going with a Darton sleeved block very soon to 85mm with 8.5:1 C/R and shooting for around 500whp on low boost. My last car was sick... 84mm sleeved GSR with a CAST revhard log manifold on stock cams and made 347whp on 11lbs or so, what ever the wastegate spring was.. If I would have went on a better fuel and a topmount manifold I would have been looking at 700whp //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif
How much do you think this project will set you back all said and done? Even tho I absolutely hate imports I may just build a sleeper for cheap and surprise people. Would be totally stock appearing because I hate rice hahagot my rods n **** finally
got my stock d15 out today.. now i gotta clean the engine bay and paint it
By all said and done I meant all the costs including the cost of the car and the total of all the money your putting in it.... Not just the basic engine build.fully built bottom end will be around $500... $300 for rods.. $120 pistons..u need bearings ect and sum machine work, but thats cheap..
x2 it can be done, but i would rather have alot more timing to play with instead of being on the edge of detonation with very little timing and the same amount of boost. But like the man said to each his own.high compression + boost is silly IMO. The energy lost by going from 9.5 to 9 is nill and the ability for mbt to not be limited by knock allows more efficient use of every pound of boost. But I know every tuner has their own opinion.
Sweet ill have to look aroundalso if you buy used items or look around.. u can do it alot cheaper
$600 for a b18a!? ****.. get them here all day for $50 lol.. thats what I put into my crx..my friend has a 92 civic hatch..spent $600 on a stock b18a motor...turbo that running 16lbs on E85 and makes 400whp and runs mid 11's in the 1/4 on stock motor.. he only spent like $2g's on his set up. just depends what goals u have. i bought my car for $600
d16 motor say $250-300 stock
Rods/pistons $450
machine work $200 cause u need to notch block ect deck it
Stock head is good for 400hp
just use stock tranny
clutch/flywheel $300ish
Turbo t3/t4 good for 500whp $650
exhaust just straight 3" is cheap
tunning is pretty cheap.. lots of free programs
fuel injectors/fuel pump $400ish
Precision SC60-1. Will be the Borg S372 very soon.My block is 8.5:1.. What turbo do you plan on running to get 500whp?
