So I believe I'm at a stage that my car basically just needs a new tune and some more boost.

By me and my friend's guesses - my car is putting down around 230-250whp
Never been to the track with it either.

I'm trying to decide when I go for my tune, whether to tell them to get me to 300whp or further? It's a thing where I go and tell them what my wheel horsepower goal is, and what psi to stop at.

Currently I'm running 15psi on my 20g (full mod list below)

While I'm sure I could go further - I'm debating whether I can do it reliably.
The thing I like about my current tune is it's pretty reliable and perfect for street driving - however it doesn't move out like I want it to. This is my daily driver until I can sell my Firebird which needs to stay in storage, then I'll buy another DD. So until then I want to make sure I stay well within my motor's capabilities.

I'm not on it a whole lot either. Sometimes my car won't see more than 5psi for days at a time - so it doesn't get beat the hell out of it. However I do put about 2,000 miles on it a month as it sits until I get a new DD.

Anyways- like I said, should I shoot for a goal of 300whp, or perhaps I was thinking about trying for 325whp? Further maybe? I really don't know - just trying to get opinions.

Here's my mod list:

Motor has about 5,000 miles on it, fresh professional rebuild, transmission also with around 3,000 miles on it.

Currently running a Keydiver Stage 3 Chip,however I will be getting DSMLink which is why I will be getting this new tune.

Just copy pasted from the modlist I have recorded on my PC

Thanks for any suggestions, comments, ando ther info!
 
IMO, tuned is tuned. you shouldn't make something do more or less than it wants to. if its tuned, than everything should be working nicely together. judging on what i've read so far on here, i would expect 300-330 at the wheels.. get your A/F ratios where they should be and see what it comes out to be, not turn everything sky high to try and hit a #. then it should be quick AND reliable..
just my thoughts

Well the tuner I'll be using is INCREDIBLE with DSM's.

They've done amazing tunes on my friend's hondas and they don't even specialize in hondas - they're DSM freaks.

Just gotta have DSMLink or AEM's tuning software. Go in, tell them your wheel horsepower goal and what psi to stop at. If I wanted 350whp lets say, and told them to stop at 20psi - if they hit 20psi and were only at 330whp they'd stop - or they'll stop where they think it's safe.

I feel my car is more than capable of actually putting down these numbers. It's just - how far should I go while trying to remain a very streetable DD car? I've never been past my current setup so I'm just kind of throwing around ideas.

Edit: I guess I should include my main goal is to eventually be running anywhere in the 12's. However I'm perfectly happy with low->mid 13's for now even. I'd just like to be in the 12's. Last time I was at the track I was in my 91 350 firebird which ran 14.5 on its tired motor that needs rings/seals replaced - so either way this should end up being an improvement to me.
 
Tune for reliability and ignore the overall power output... Your setup should net you around 300. Just tell your tuner everything that you are telling us here...

While I'm not power crazy as most people are - I definitely would like as much power as I can get while staying well under the "maximum my setup can take". Yes i'll be telling the tuner all this as well.

Simply trying to get some ideas from people who've been around longer than I on if they think my setup is ready to handle 300 or more reliably.
 
I would tune it to be safe around 20-22psi. Those numbers will be safe on your setup, and it will still be reliable for a daily driver.

Basically no matter how high you decide to push the boost, it will still be okay while cruising, that's the best part of having a DSM. They can be fast as hell but still drive around great.

Well I'm hoping with what I'm probably making with my current setup at 15psi - that I'll be able to get my 300whp goal before 20psi ( assuming that's the route I go )

Because sure my long term goals are 11's - but we're talking awhile until I can afford another new DD and I'm out of school / my min wage job.
 
Your mod list looks solid to net 300-350hp with a good tune, but I don't think some bigger injectors would hurt. Either way if you turn the boost up past 20psi you should notice a big difference since that 20g at only 15psi is probably pretty laggy.

Eh its not to bad, it comes on pretty hard around 3500.

Works for me that way though as I like to stay out of boost when cruising around, I'm just paranoid about my car :p A bit laggier helps me stay out of it.

And yeah injectors are on my list of things to get.

Aside from DSMLink I really need some new springs which I may just go ahead and get Goldline springs again - they aren't fancy but they work and are cheap.

After that I'd like to get some 1000+ injectors and possibly look at tuning for e85
 
Well I just got my 20g from jusmx and I plan on running 22-24lbs of boost on it daily. My mod list is somewhat solid and somewhat comparable to yours bro. As long as you have a solid tune you will be perfectly fine and shouldn't be paranoid.
 
it sounds to me like your not even starting to see the potential of your setup. stock 6-bolts have been takin past 500hp, and thats with no rebuild. you have a pretty stout setup, that 20g should be able to get you somewhere close to the 400 range with . your motor will still be plenty happy, but you will need bigger injectors when you switch over to link. i say tune it for no lower than 25psi, she will take it fine
 
^^ The 20g isn't really going to go much further than 25-27lbs of boost bro. If you really are looking to go that far with the turbo atleast get the tdo6h.....
 
he said he has the tdo6 housing, thats why i said that in the first place.

20g: td05 turbine housing (clipped to Buschur specs) and a td06 compressor

Exactly what I was trying to say, just worded much better ROFL

+1

In the future I plan to look for a 2g awd 6-bolt and do this setup. I'm missing 3 pieces to the puzzle :ohdamn:

Meh, I say 28 psi :toobad:
 
^^^^^
honestly unless you alredy have a 20g, i wouldnt even bother with it. there are better turbos for the money. it is a prover turbo, so its really up to what you wanna run.
 
Okay - so maybe I'll raise my goal a bit and have them tune for 330ish whp.

Right now my tune is pretty crappy so anything's going to end up feeling better :p

And will be 650cc's be enough do you think for a 330whp pump gas tune?
 
If I were you I would go with bigger inj. since you will probably be very close if not maxing out those 650's right around 20-22lbs of boost
 
So my 650cc's probably need to be bigger for 300-325whp?

If this is the case it'll be awhile longer before I get my new tune... I'm really strapped for money and figured I had what I needed to go ahead and get DSMLink / my tune

Bleh
 
well go ahead and get what you can out of what you have now. no need to rush things. ive hade my car for about 5 years now and i started tearing her down to rebuild her. mostly cause i didnt have the time or place to do it.
 
How much are you spending on your tune?

I think you will find that it is pretty damn easy to tune the car yourself with dsmlink. So you can tune it yourself and then just pay to go dyno the car, should work out to be a little cheaper.
 
look on the marketplace im sure you can find a set of 750cc for a good price dont get all discouraged cause you have a set back shit happens and at least its winter so you can save up till spring and bingo your set......but i doubt you hit 300 or more at 20psi unless you run higher than 91octane, glad to see you joined the site andrew theres alot of knowledge for you gain here!!!



p.s. you need a set of hks 272 cams!!!

Yeah - well if you didn't hear I lost my job haha - so I'm trying to budget myself for now within my tax return. And yeah I've been learning a hell of a lot from this place. Brad and me found out too what my "exhaust leak" and "wideband issue" were.. My downpipe was missing a bolt and the other bolt was loose and there was no gasket to speak of. We got it all fixed today and she sounds great and my Wideband is 100% accurate now haha.

I'd just like to get 300whp out the thing for now with a good tune rather than that keydiver chip. I know John is getting around 300whp out of his civic with 550cc injectors but I'm not sure how similar our fuel systems are.

I did sell the laser for $850 so I have a bit of money to play with but I did use some of it to pay off the talon+insurance for 3 months.

Anyways - I'll start checking the marketplace for some injectors, I'd love to find some 800's or higher.

And I'd love some 272's but I wouldn't know how to put them in at the moment let alone be able to afford em haha.
 
Your set-up can easily push 350 if not bigger. Do not underestimate the 20g. A 16g can easily push over 300hp and the 20g is much bigger. Push that baby over 22lbs and you'll be in the 350hp range with a decent tune. With that big exhaust it should breathe really nice. And yes the stock 6-bolt can handle 500hp so don't worry about anything breaking. Just max out your injectors to their full potential and have fun.
