boost and high compression EA82....
#1
Posted 26 May 2006 - 10:40 PM
carbed EA82
gen 2 turbo heads
o-ringed block and heads
copper headgaskets
new headbolts
port-n-polished heads
port matched intake/exhaust and heads
my current setup of bolt ons (TD04, cold air intake, spyder intake, WRX TMIC, etc.)
fuel mods like 280ZX turbo injectors and AFPR
then I'll be getting a MS setup as well, later on this summer hopefully.
Wold this combination be able to handle 12psi as a daily driver possibly? Thoughts/suggestions/opinions/critisism is welcome

i would say 6-7 PSI would be good with high comp. but i dont think you can go that low with a td04..

This will give you what you want while still maintaining as much stock equip. as possible which will save you much time and headaches. If it gets a bit wierd at higher fuel pressures consider running without the O2 sensor connected. Spend the money on the good bellmouth DP and exhaust and a good TMIC setup, help it breathe.

what kw/hp do you estimate at this boost,with your set up...??I take mine up to 12 psi WOT sometimes more.
also i keep my rpm under 6800,would this be the limit with your set up too??cheers

I take mine up to 12 psi WOT sometimes more. SPFI block TMIC 86 computer and maf. Run it rich. Don't bother with the port and polish, make sure the intercoolers pipes are smooth tho nice transitions and corners. Stock engine management with fuel pressure around 40psi or so with AFPR.

I have a AFPR on the way as we speak and currently saving a bit of cash to get the Nissan 280ZX turbo injectors off of ebay. I do know however at my elevation, I can run a wee bit less fuel pressure since I am 7200 feet above sea level but when I move to Washigton, thats what I'm worried about. I also have a 3" bellmouth downpipe on it as well. As far as breathing, I think it does it very well with a custom cold air intake, TD04, and my WRX TMIC...

Caboobaru are you sure you need the nissan injectors?
I really need a DP for my TD04 I see WJM has a stromung for sale but it's got a divorced wastegate and I want a bellmouth. Volume is where it's at.

I take mine up to 7500 rpm fairly often, #'s? I'd estimate a realistic 180chp tho I'm sure it'd dyno a bit higher...
Isn't this the guy who was bashing dynos and getting numbers in another thread? Why not just go to a group dyno day, spend the $45 or whatever the group rate is and get a couple of baseline pulls so if someone asks, "What kind of power are you making?" or "What do your REAL A/Fs look like at 7500 rpm?" you can do what WJM has done time and again and throw some HARD data their way instead of, "Well it might be making xxxhp and xxxlb/ft, but I really have no clue what it makes or what its doing at that rpm". Sorry for the rant, no harm or offense intended.
Oh, and Sport Compact Car is a kick a$$ rag, don't diss.

Uhm well I was going to PM you a response but hey I love a bit drama..
Take another look at that post, like I said I'm not about to go an dyno my subies just for the sake of telling others what #'s I had on such and such date. I'll take that money and spend it on my kids thanks.
I was pointing out that to "tune" a car doesn't mean you need a dyno and that there is a difference between a #'s run and "tuning" in more than just dollars.
Understand?
I have no clue?
don't diss?

as opposed to a RRFPR?
i remember calebz talking about a steel insert for the headbolts, you might want to look into that.
what are you using to control boost?
