i have done the searches and posted preveously, but i'm still confused with people arguments w/ right or wrong.

anyways, I'm going to put my brothers 1g dsm turbo on my b18c1, and people on this board have said that i can get 7psi on stock injectors and all i need to upgrade is fuel pump(bosch or 255walbro?),8:1FMU for my fuel needs and that if i wanted to boost to 10psi just get 310cc injectors.

i have read that people blown there motor with 7 to 10 psi, will i detonate with those fuel upgrades suggested? I am talking about initial start up after installation without any tuning. i will have my engine tuned properly and monitor it closely!

what kind of hp gains can i get with 7psi 1g dsm turbo?

 

23 views and nobody knows

what board is this agian?

 

If you get enough fuel with the 8:1 rise rate with the stock injectors, then it may work.

 

how will i know if i get enough fuel if i have'nt even bought the parts yet and installed them to see if i do?

I figured i could ask on this board and someone could save me the time and money and tell me what will work and not work with this 14b turbo setup and how much hp increase i should be able to get if tuned right, so i will know what to expect come dyno time.

i need anwers not guesses

 

Sorry...missed the part about the DSM turbo. I don't have any experience with that turbo. But since you are going to the dyno to tune it, why not buy the parts you know you will need and get an FMU recalibration kit($50) with the various disks(12:1, 10:1, etc.) and try them out. Only takes a couple minutes to swap them.

Just a suggestion in case you don't get the answer your looking for.

 

7 PSI on a stock DSM turbo MIGHT make 10 HP over stock

J/P.

But anyway, the DSM turbo's are so small, it's not worth the time or money to put such a puny thing as that on an Integra... Spend the money on bolt ons and get more HP out of it, is my opinion.

 

why you say that? 10hp over stock! Have you tried it yet, probally not!

If everyone else is only runnig 7-12 psi on stock internals with t3/t4 i know that the dsm 14b can produce at least 275 hp if not more and have a lot better spool time. is there any reason for spending up to 1000 dallors on a t3/t4 just to run a measly 7psi to 10psi? not for my case A FREE 14B TURBO "BRAND NEW" i think i will use free turbo and spank most people on the street in OKC. and be able run mid 12's with my gutted HB. 14b ALL-DAY

I just figured that the honda sucks more air in than the dsms especially with VTEC and would ask if anyone has actually tried this setup and see what thier opinions are whether i should just keep the 14b stock and have great low-end power and when Vtec kicks in the Turbo will still be able to supply enough air in the high-end 8000 rpm range or do i need to get the 14b clipped and sacrifice low-end power for more high-end power and be able to supply plenty of air at 8000 rpm.

 

See that....he said J/P...probably meant J/K.

The 14b is going to run out of steam above around 6000 rpms. Yea, you will have good spool, but you won't be pushing much but hot air in the high rpm range. Hot air leads to less power, and possibily alot of detonation.

I suggest you take a look at some compressor maps for a 14b.

J/p = Just playing...

I dont kno how much hp u will gain...depends on a lot of factors. I suggest u save up for a t3/t4 turbo. At the same boost it will gain a lot more power than that mitsu turbo.

AS for the fuel. Fmu and stock injectors should work for 7psi. You should also get an inline or intank fuel pump. ANything higher...i suggest u get bigger injectors.

 

7psi, piece of cake. You will need a 10:1 disc, not an 8:1. You will need a Bosch HP pump or a Walbro 255l HP (high pressure not high volume) pump. I recommend an MSD BTM to retard timing under boost. Injectors can stay stock, for now. Anything over 7 psi and 310's are a minimum. Invest in an intercooler, you will need it. The tD04 is still a little small for 1.8L at anything over 5500 rpms and you will notice it. You will see about 40 to 50% increase in torque if you can get the fueling right.

Check out my site and you will see some of the things you will need to do this. Its for CRX's but still good ideas.

BTW-When you are ready to upgrade, the 16G will bolt right in.

 

IMO, A 14b on a GSR will act about like a JRSC on a B16a... Lots of bottom end, not alot of peak HP gain.

It's just NOT worth the hassle of actually putting the turbo, intercooler, and the fuel items needed to get it running.

The reason everyone put 4/3 hybrid turbo's on te cars is because at moderate streetable stock engine boost levels, they make an assload of power.

220-250 at the wheels on a stock engine with 6-8 PSI? I like the way that sounds. How about you?

 

well the only thing i could find was the 14b produces practical 385cfm @15 psi
i wish i could find someone who has tried this before but i do know that alot of DSM guys have this turbo running at 14 to 15 psi and say they have no problems with getting hot air. So i figure that @7psi i should be okay because i will barley be pushing the turbo.

I'm still confused about the Hot air problem at higher Rpm's,
(say 6500rpm @15psi is it's max for 70%efficiancy cool air 30%hot air for a 14b) is it since the motor is moving at higher rpm's the turbo is spinning at higher rpms than designed for efficiancy and then the turbo starts to blow hotter air because the turbo is getting hotter and going below the 70%cool air and then you just start blowing hot air. (but i Know that the intercooler cools down air?)

 

dsm turbo on integ=

 

OK guys you have convinced me to get a BIGGER turbo will the T3/T04E be okay with you guys?

So the T3/T04E is the best for the street and could be a beast on the track

how much does a T3/T04E cost???? and what trim should i start out at?
I still don't qiute understand the hot air problem but was I close?

thanks guys for all the info

 

Man, I have been very impressed with the TD05h 14b 1g dSM turbo on all my setups. I have seen lots of stock 1g DSM's pulling 12's on their stock turbos. I dont see why you would have any problem using this turbo,

A t3/t4 with a 60trim (.48ex) flows around 500cfm @15psi where a stock 14b flows 420cfm @15psi. They are pretty large turbos, but I have never put a 14b on a B-series motor, just D-series.

Good luck with your project, and if you do decide to get a t3/t4 setup email me I can refer you to a decent place.

i second that

 

if you want jrsc type gains run the dsm T
but back to the question

get the fmu and thats it. you might be able to get 9 psi out of the injectors.

that t25? or 16g will give you very lil lag or spool time.

but...
smaller turbo means less gains per psi
ex... we see about 10hp per in t3t4's
and you might see 7hp as a guys

you will hit max boost b4 us though...enjoy it!
