Whats up fellas, let me start out by saying that i have searched for this answer but did not really find what i was looking for.

Few months ago i bought a set of injectors which i thought were 550cc, when i received them they turned out to be 750cc.

Im planing on boosting my car with and running about 6 or 7 pounds. My question is would the 750's be too much for a small turbo setup or would they be fine?

 

turn down the injector duty cycle when tuning and you'll be fine. it will just hold the injector open for a shorter time, due to the larger flow.

 

thanks for the input, anyone else has an opinion?

 

What are you tuning with?

 

im going with the cheapest way and going with the SAFC, money is kind of tight right now later on i would get Hondata and do the right way

 

Not sure if you can lean that out as much as you need to......

Why bother Turbo'ing if you're tuning with an AFC? Another slow H22 with a Turbo!
Damn........Budget Turbo H22 FTL!......But WOW it looks nice and may win you a trophy at a car show......

Riddle me this 97 Sleeper:
Whats your plan if your motor pops?(if you're tight on money right now)
How is a high 13sec Prelude a sleeper? What are you sleeping from? Another Prelude?

 

750ccs will be ok, however don't expect to run them on a AFC. Even if an AFC does have enough authority over every part of the load/RPM range to make the engine run, AFCs have side effects on ignition timing which could be a major problem when pushing the fuel trim adjustment feature as far as possible.

Also, don't expect to run a turbo car on an AFC either. Your stock ECU doesn't know what boost is.

 

We did OK with my friends car.......287whp@10psi with DSM 450s(RC b&b) and a VAFC+stock P13. IIRC we used the FMU :p :thumbsdown:

 

Making power is easy as long as you know how to tune a car, and how to use the unit. There are people making more power with a crome then with Hondata. Im assuming that makes hondata shitty because you will have a slow prelude and then it will be pointless. Beside, I can guarantee if you run between 5-7psi and a right tune, your engine will not blow and later on when you are financially ready you can upgrade both the motor and the ems.

I know a guy making 400+whp on a maxima with a safc, and has been doing so for over 2 years without any problems.

 

Hahahahahahahaha!!!!! SURE!!! The only guarantee is there is no guarantee. How can you guarantee Metallurgy???

and BTW, I doubt Hondata cares what people are doing with a Hack Setup like CROME!

 

According to Bob ^ here, I guess you should be running something like a Motec M880, in order to make your car "fast".

 

Na, you just shouldn't bother with 6-7psi........

 

Lol. Internet tuners ftw

 

First of all, you're an idiot! why are you incorporating my screen name that i made up when i joined the website, about 4 years ago, into what we are talking about here?? I know that the plan that i have described is not the ideal blueprint for boosting a car, however this is what i have so its all that i have to work with.

I appreciate your input in this matter, but your dumb analysis of my screen name is unnecessary

 

Back on subject kids. I wouldnt use the afc. you can easily chip an ecu and tune on crome for less that 75 buck which is way less then what you have in those injectors alone. another thing H22's are no good for running that much boost. the cylinder walls are junk. you will have less time and less asprin needed for that bas *** headache if you just use crome or any other tuning software and make more power

 

lol, i have a question. do you know how to tune? hahaha

 

dont go with a SAFC.

^here are cheap tuning options^

Just save your money and do it right the first time. This also isnt a good forum to ask a question about boost. This is a prelude forum... Check out the forced induction thread for better info

 

If you tune with crome or uberdata the biggest problem you will encounter will be getting a smooth low idle since those injector are designed to flow so much its hard to get them flow just a little, I am running 750's will a little about normal idle and I am just happy. If you want to build a budget turbo I say go for it but plan for a rebuild. Thats what i did, No regets./

 

Have fun with your slow unreliable turbo setup.......
Still curious to what your Plan B is when/if the motor pops? Bus rides or bumming rides from friends? Mom and Dad?

 

this guy's a douchebag^^^^^^^^ just cuz you have a fast prelude and can afford the quality parts nowdays doesnt give you the right to be a dick to other members. im sure you used low quality parts at some point in your lifetime with cars. youre the reason h-t members have a bad rap for bein dicks

 

actually the reason HT went down the drain is because people with no experience started talking out of their *** and all the people who actually have experience gave up trying.

your car will run like complete ***, will make horrible power and will likely start smoking after a short while due to all the fuel washing the rings of their protecting oil layer between the ring and cylinder walls eventually eating themselves alive and draining all your compression through the rings and thus calling for a rebuild.

sit on that and spin.
