fmu question
 

now i almost got my full kit ready for my h22 prelude.
i have
t3/t04e
3"downpipe with closed loop wastegate dump
greddy type s bov
ss oil lines and fittings
FMIC
top mount mani

and i still need wastegate/intercooler piping, injectors, fuel pump, hondata etc.


now my question is my tuner is 3 hours away in a different city.

if i install my kit and just install a fmu with stock injectors/fuel pump will it be safe enough to make a highway journey 3 hours out of town or should i tow it?
(---- load of money)

i wouldn't be doing any full throttle pulls or anything haha. just conservative to the tuner. basically babying it.
towing would be around $500-$600, driving equals 40 bucks for gas and my buddy would buy the fmu from me afterwards.

Re: fmu question
 

Um, it seems all you have is an FMU?

Run stock injectors/stock ECU, disconnect the upper charge pipe and throw a filter right on the TB and run with your wastegate open. Reconnect the pipe, swap ECU's and install your larger injectors when you get to the tuners :)

Re: fmu question
 

thats another idea. i heard you can overspool the turbo that way though

Re: fmu question
 

When you drive it to the tuner you should be fine...I would just make sure that there is NO way to develop boost...I.E. loosen one of your bolts on your blow off valve to make sure you can't build any pressure.

BTW...you put Hondata on your list of things you are going to get. If you are going to use Hondata, Uberdata, Chrome, or any other "stand alone" system you do not need an FMU at all.

Re: fmu question
 

i was just going to get a fmu just incase i built boost. i could always just run with the gate open/loose bov

Re: fmu question
 

Well I never said rev the piss out of it :l Drive like a normal human being, shift at 3 grand and just watch yourself... I'd really recommend taking off that top pipe though

Re: fmu question
 

skip the fmu and just drive it with the factory fuel system.

a t3/t04e is gonna take some rev's to spin boost i would imagine that you're not gonna start spinning it until you're into 4000's, so just take it easy.

besides, worst case is you're gonna spin up more than a pound and the ecu will plop you into limp mode and fall on its face.

Re: fmu question
 

^^^^ What he said. Just don't be stupid about it. I can drive around on a small ass turbo and not boost. If you need a little more power without boosting, just rev it higher, BUT DON"T BOOST.

Re: fmu question
 

at 120km/h on the highway im at 4g rpm haha. turbo is supposed to spool at 3500ish. bad gear ratios to be trying that. i might just take off the top pipe, run open wastegate and try to keep the revs down. or tow it. i need a few more quotes

Re: fmu question
 

It doesn't matter what rpms you are at. If you're cruising on the freeway the won't be any boost. Don't disconnect anything. JUST DON"T BOOST.

Also keeping the revs down is were you would be getting into trouble anyway, since the total gear ratio will be longer and you will need to put more of a load on the motor to get the car moving, thereby, getting into boost.

Re: fmu question
 

Fabricate a solid plate to bolt between the turbo and manifold so the turbo never even sees any exhaust flow.

Re: fmu question
 

The point here is to prevent boost without making it difficult.

You numbnuts make ---- way way harder than it has to be.

Re: fmu question
 

Now what? take a look at what you just typed and tell me if the car would even start :1 DUH!

Re: fmu question
 

:)

i might just try and drive it and don't boost. i can't see passing on the highway being any fun though. i still think the best/safest way is to tow it. its just expensive. ive drove turbo cars before. i used to have a volvo s70 t5 and it was hard to keep out of boost and it didn't spool until around 3500. i could disconnect a charge pipe, but its a long ways for that.

Re: fmu question
 

Personally I would just look for a friend with a truck and an auto trailer. If you know someone who is willing to help ya out then I would do it that way. :P

Re: fmu question
 

just rent a uhaul and park it in the back haha

Re: fmu question
 

staying outnof b00st is up to your throttle control.

Re: fmu question
 

do what fook said and stop ------- complaing, open waste gate leave charge pipes on, even if you did get on it at you will olny build a couple pounds at redline, so stay down low and drive like you mom

Re: fmu question
 

i think once you know what boost feels like and have driven iwth it before you'll know what everyone is talking about ... looks like you havent felt or driven a boosted car before
miss n00b booty

Re: fmu question
 

my previous setup built full boost (10-12psi) at 3500RPMS, i drive at about 70MPH and pass on the highway and never get into boost

it's called throttle control! just drive it and quite bitchin ya pansy

Re: fmu question
 

I guess I should have also said "take the spring out of your wastegate" too.

Re: fmu question
 

a solid plate between the mani and turbo blocks exhaust flow from the motor numbnuts

thats what he meant.. no path for exhaust = non running engine

Re: fmu question
 

who said i was complaining. would you risk a 3 hour trip with a $3500 motor. what if all of a sudden you need the power to get out of a situation. motors gone, or you get hit.

theres a lot more to it then just to "take it easy"


i will tow it. or pull it with my suv. im not going to risk it.

Re: fmu question
 

your ecu will not let you boost over a couple pounds

everyone use's the bullshit "what if i need the power to get out of something" exscuse

if your a big enough dumbass to get hit without boost god only knows what you would do to yourself with it.. drive it to get tuned or sell it because if you cant handle keeping your foot off the gas you'll kill yourself anyway

i will be spending 3 1/2 hours to goto my tuners on a basemap after break in on my motor and i dont care, im not stupid enough to drive close enough to people to "need" power to get myself out of anything

Re: fmu question
 

This is what I had in mind... Disconnect charge pipe and somehow cap it off, and pop off your BOV. if anything, just a little. My thoughts are the only reason it would overspool is b/c it won't build up any pressure to give the turbo any resistance. so if you have a small outlet to let off the pressure and it doesn't overboost and pop somethng then it should be fine.

Obviously keep w/g open while doin this.

Any thoughts?

Re: fmu question
 

Yeah, it blocks the exhaust from getting to the turbo, so instead it goes through the wastegate (if he has an external gate.

And my nuts haven't been numb since that time I sat on the can for too long and my entire ass region fell asleep.

Re: fmu question
 

i have closed loop external gate

Re: fmu question
 

Since your gate is internal, disconnect the wastegate arm. If your turbo is like mine, when the arm is disconnected, no boost is made since the flapper stays open. I drove from Frisco to LA and back like this (about a 1000 mi trip), and never seen any boost :'( (my homemade arm fell of a few days before my trip)

Re: fmu question
 

maybe i will drive it then with open gate haha its a 38mm external gate routed back into the downpipe.
loose bov and open gate should equal no boost. im still undecided.
towing isn't that much with my suv. rent a trailer and thats it. driving it would be better though.

Re: fmu question
 

just hook up the fmu, and drive to the tuner! It won't cause any harm.

Re: fmu question
 

Since you have an external gate just take the spring out and it wont boost at all. Problem solved. :6

Doing it this way you dont have to worry about revs and boost, just drive it how you normally would.

Re: fmu question
 

This is a sad thread. Just drive it easy

Re: fmu question
 

yeah this is dumb post you dont even need an fmu you will be fine if you dont floor it

Re: fmu question
 

what are you gona tune with when you get to the shop? i hope not with that FMU. your engine cost 3500? damn, thats the most expensive h22 ever. is it even built?

Re: fmu question
 

i highly doubt he's built it for boost already and is still pieceing together his turbo kit, he still needs at least 1/4 of his kit

if he's spent that much to try to turbo a stock H22 i feel sorry for him :l

Re: fmu question
 

i exaggerated my 3500 haha
thats with my tranny but whatever.

im tuning with hondata s200 w/boost and a plx m300
i will save the walbro/injectors,etc for the shop to install when i get there.

Re: fmu question
 

if its a stock H22 your motor is deffinitly not worth 3500, even with your tranny.. i can get one for under $2000 with tranny, under $2500 with tranny, axles, ecu and harness

drive it and stay out of boost if you want to drive it, simple as that, its not going to hurt your motor

Re: fmu question
 

i,m talking CAD currency and i have a 1500 dollar LSD tranny
but thats not the issue. i will make a decision when the install is done.

Re: fmu question
 

hahahahahaha

oh im sorry... thats pretty sad..
