Hi, It's my first post here in this forum, i hope that we can help each other regarding Civic tuning, i'll try to get pictures along the route so you can learn from my project if your intersted, my project is as follows:

- TD04-09 Turbo(Old GT3000/VR4 Mitsubishi)
*planning on running low boost for starters.

- Custom Turbo Manifold
*Gonna flip the stock header verticly 180* so it is pointed up, then cut the part that is after the 4-to-1 transition so i could not affect airflow distribution, and weld the TDO4-09 flange from the original TDO4 turbo manifold there.

- Custom turbo piping
*Generally i'm going to use the same pipes that is used for plumbing, using a saw and alot of L-type pipes, then i'll upgrade later(when boosting higher) with sending those pipes to someone who could make me iron ones.

- Oiling for the turbo
*Is done by connecting a small hose from the oil sump to the turbo and by using a small pump between the hose and the sump or turbo.

- Fuel Manegment Alternative
*Gonna be using a simple mechinical device which would raise fuel pressure each PSI increase in the intake or exhaust whatever..., called Fuel Management Unit. Note: I don't know if i should convert the fuel system to return type or not to use the FPR or FMU i ask you..?

- I can't get a hold of RSX injectors will the K24 accord injectors work?, thank you

Tell me your opinions and what you think, and what would save me costs for the future. if all worked well then it will cost totally about 800$'s... don't tell me it won't work cause you have payed alot for another kit... right now i can't afford a kit so i will make my own seen it work on other cars before, wish me luck!!!

If you can't afford a new kit I'd personally use that money and buy a used kit. Are you serious about this bro? I think there will be some serious roadblocks that you'll run into but I'm no turbo expert.

Ok Im not gunna be mean, but I will tell it like it is, hehe.
Dude, you are gunna ruin that thing. LOL. DONT use an FMU, they suck *** and it will create more headaches than it solves in this case. At least try to run an emanage, with those RSX injectors. Why do you need to run a pump to oil the turbo??? You can tee off an oil feed on the block, then run the return down into the pan. I'd wait a lil while and do lot more homework on this project before starting or buying anything, these cars are f**k to boost correctly. Back yarding these car usually ends in a trip to the junkyard to buy a new engine, and parts to put it back to stock, hehe. Arent those TD04s super small??? I havent seen one in a while but I thought I remember them being absolutely tiny. Get a T25 if thats the case. The mitzu turbo is probably junk anyway, most of those cars were junk the day the rolled out of the factory,lol.

Try and get a hold of a used kit man, they go for as less as 1000, thats what 200 more than what you are planning on spending with the home in the kitchen kit.

I know an FMU will suck... But it's a temporery solution that i'll fit to get this turbo up and runing safely, it's ok to run a little rich, after all... an FMU is just an alternative to ECU programing and pigyback's, so, ok... their is no need for small pump to oil the turbo lol... I'm totally convinced with the Mitsu turbo's... it is cheap, and it's like 60 hp at the flywheel for 7 PSI, pretty decent for a small turbo, can't lay my hand's on either RSX injectors or T25 turbo, so i'll stick to the TD04-09 the importent thing that i want to achive is know there is a runing turbo in my car with a decent PSI... i'll upgrade parts within 3 weeks

It's not that easy here to spot a D17 turbo kit... all tuners drive H22's and B16's... I'll be a first in the group, and online purchising is not an option, so i guess your gonna wish me luck

and what about the intercooler?

o yeah well good luck for sure, see its been almost a year and i am still trying to peice my custom kit together and so far I've spent almost 3,000, with what i've spent i should have thought twice and saved up to get Dezods kit. I

These can be taken from turbo diesels for very cheap, i remember seeing an Isuzu truck intercooler fitted on a 30-PSI turbo'ed Hyundai working just fine...

Thanks... i'll keep you posted with anything that will happen, probebley gonna buy the turbo unit tommorow, so until tomorrow... now i'm going to sleep...

Just hope that FMU doesnt lock up those injectors. They run at almost max (safe) capacity from the factory and they arent anything heavy duty. 60whp@7psi on that thing with no descent tuning will be a big stretch. Im not trying to be a downer but that TD04 exhaust housing is gunna choke up the top end. Its gunna pretty much spool at idle though, hehe. Better off grabbing a used wet kit.

dude, for future reference, ive got a d17 bottom end ill sell you when you grenade yours. what about boost management stuff? im no turbo whiz but i say youre about to have problems and one nasty *** lookin setup. you have got to live in the boonies somewhere to even come up with an idea like this. not good chuck.

 
Rep Power: 303

i can agree with most here and also see the OP's point. he wants a budget backyard kit that works. there have been plenty of people out there that are able to do it.

ok as far as the FMU goes. as you know we have a returnless fuel system. you can create a loop while running the FMU and simulate a return style while using a FMU but if fuel pressure drops your going to be up the creek. I know of people that didnt use any type of fuel management on 4psi and have been driving around for 2+ years now. another that just connected a 3 bar map to the stock wiring and hasnt changed anyhting and will boost 6-8 psi. so i see your point. but this fuel system is different. the injectors on our cars usually hang around 85+% as is. your not going to be able to boost anyhting more than like 2-3psi on these injectors. as far as an intercooler is concerned i would look in to a dsm side mount. cheap and they work great for low boost. your also going to have to get a bypass valve and boost controller. the bypass can be found on 1st gen eclipse's for dirty cheap as well. you should just loo kinto a obx manifold and strip and reinforce it. either that or create a down pipe and use a dc ex header in its original position. the turbo is small and remember that at high rpm's your going to create a lot of heat, so you may want to move the IAT as close the the T/B as possible. or right the the exit pipe for the I/C.

i understand your thinking. but i have also seen many attemp this an fail miserably. if your serious you should check out www.homemadeturbo.com and also get the book "Maximum Boost" by Corky Bell

wow...i applaud you for your efforts , but like everyone else has said, search the for sale threads and i'm sure you can pick up a used kit for pretty close to what you're planning to spend going this route. and it'll have much more reliable parts and if there's any questions you can always ask the person you buy it off of

 
Rep Power: 303

oh yeah and just to add the reason why FMU's are so frowned upon is because they create lean spots during partial throttle and inconsistant afr's. you want a fluxuating fuel curve as to where a FMU only gives a certain pressure per the vaccum it reads.

 
Rep Power: 297

Im not knocking building a cheap turbo setup, I have done that stuff too but there are just some things you DO need that unfortunately cost money in order to build a reliable car. If you were putting together an older car you'd be in much better shape. Just think about how cheap it will be to replace a motor or two, its more cost effective to spend a lil extra up front. Patience is key.

its all over right here.
1. The header flange isn't symmetric. So you cant flip it.
2. The hood. By the time the header runners are close enough together to weld a collector on, then bolt a turbo on top of it, you're through the hood.
3. The original manifold is probably cast iron, this one is low grade stainless. Good luck welding that.

By this point, if you haven't figured out you should just build a real turbo manifold, I don't know what to say. The old school ghetto HX manifold with the DSM flange on it doesnt work, they're not making cast short manifolds anymore, they've smarted up and started making tubulars.


From there, everyone's covered the bases. This isn't an OBD0 car. It takes some technology to make it run right.

so true, nice job breaking it down.

i had a whole post written up last night but for some reason it didnt take. in response to 02fpcivic i also have built my own systems. on my last one it was for a 01 s10 2.2l 4cyl. truck makes about 90whp stock. with the remann'd garret t3/t4 50trim with .48a/r on 10 psi it made 224whp. i put together the kit for under $1500 with everything new besides the turbo and EBC. this is one a totally stock motor with just a efan and exhaust for other mods. it was verytight fit using a up pipe off the stock manifold to the front of the motor where an efan replaced the stock fan assembly.

my point is i know this guy wants a budget build and his $$ goals are pretty tight. but it can be done. as far as using an older beater to play with, the D17 can be had for $200-500. tht is about as disposable as they get. just because its in a newer chassis doesnt mean much.

Now boiler has basically laid it down in good terms. realistically its going to be more expensive because of tuning.

as far as trying to deter this guy from doing it, i dont think its going to happen. so we may as well just try to help him get the right parts for cheap that we know will work rather than not providing any help at all. after all it is his car and if his mind is made up there is nothing we can say to deter him from proceeding.

if the right parts are bought it is definately possible for him to pull this off. tuning will obviously be the major issue but let him figure that out.

Tuning is the reason why most turbo setups fail. ****, the whole turbo setup on the H22 accord we built was only about 1500 and that laid down some serious power. However, it only took us about 5 minutes of driving to realize that we needed to spend real money here and there, esp. on a nice hondata unit. I say go for it. Just as long as he knows, nothing is ever as easy as it sounds. Not trying to be a downer, just trying to be realistic.

Yes tuning is key in a turbo setup, but as i said... a FPR or an FMU is going in for now with big injecters... i think the car will run pig rich... but that's better for bieng safe, as for the stock headers not fitting if fliped, that's ok, i'll either fabricate one from scratch, or i'll just try to weld the stock header opening ports with the original turbo manifold of the TD04-09, once the turbo is up and running, it's just a matter of weeks, tell i drop the affordable standalone (MegaSquirt) or an AFC(I think...) but i don't like piggyback's that much, a chipped obd-1 ECU is not an option too cause i have an Auto now i'm going offline, if i come with the turbo next time i'll post pics, c ya

 
Rep Power: 297

I can see the future. It includes lots of CELs, hehe. Haha GL man running those injectors without cutting them back is gunna result in CELs up the ***. While you got the camera out, take pics of the engine now. Then you can have a picture titled "just before internal engine parts became external engine parts"

this kind of homemade turbo **** is not for newer cars, this is the kind of stuff people do to older cars for shitz and giggles for minimal costs...
