Help need tech advice..

[Hath]

right i logged on a long while back. i still have my civic.. it is a JDM import civic vti ( i am from the uk ) 1.5 (1499cc) 16v SOHC VTEC, right now as it went i have received more points from the plod. now points do not mean prizes... infact it makes my insurance crack its whip out and slip me a big enema.. i was going to place a B18c out of a intergra type R in BUt i cannot insure this.. i can however insure my car wiht curretn engine to be turboed.. i ahve seen a lot of kits on ebay.. anyone care to give me any info and weather the job is easy to do with some mates and beer at home.. i dnt facny letting a garage haul over my car.. i like to learn.. i knwo the engiens able to take this but i would really nejoy some tech spec form some gurus out there.. any help would be most appreciated :)

Hi Hath,

Welcome to JDMST

Any turbos that have been tested by reputiable workshops or engineers are sometimes the way to go.. Lots of people I know have bolt on turbos running mild boost on naturally aspirated engines.

It really all comes down to the tune as you may know bolt on parts are what the title says "easy to fit" but you really must know what your looking at.

I'd sort out the igniton and fueling as the bassis of a turbo addon. Ie run colder plugs and set the correct timing so it doesnt detonate or ping. And with fuel have addequate supply.

I know Zi built and tuned his Turbo Civic in 3 days flat, but then again he had the help of Westside who can custom fabircate anything on the spot.

LOL @ Beer.
Turboed VTEC... awsome.

Who are you insured with. I'm with Just Car, they are expensive, but will insure you for virtually anything. When I was looking at my DC2, I also had an EK1 with B16B conversion in mind. Just car told me, that you were insured by the Chassis... not the engine. So infact they would insure you as an EK1, and charge you for that. An engine swap is just classified as a modification, and would not affectively make your car a EK9.

[project2]

Umm guys his from UK.. So insurance ofcourse is different

[VTECMACHINE]

ohhhh didn't know that... soz. I didn't read the stuff in brackets... lol

[Hath]

cheers guys, yeah im form the uk lol :oops: have found a decent kit on turboktis.com stage one.. wiht that i still need a mangement and fuel system upgrade. looking at a walbro 255lph and ubersate ecu should be alright..???? aparently after reading lots my stock interanls will cater for upto 8 psi..wihtout deciding to melt? only thing i will need to change is the clutch due to the change in power and torque.

only thing i will need to change is the clutch due to the change in power and torque.

best idea is to up your suspension and brakes to cope as well, more so on the brakes

[Hath]

already done that son :).. i have DC2 ITR discs and calipers on the front wiht a uk spec VTI rear beam disc conversion, plus Tein coilovers.

I'm not a guru, but this is the road I'll be walking down say February / March next year. So, from my research, this is my opinion, and it might not be worth jack shit. But


Uberdata is tricky if you dont know what you're doing.

you'll need injectors, turbokits.com is pretty reliable.

D15 VTEC...

im thinking you've got the D15B from the EG4?
I dont know of any D15's that are 1499 cc....

Compression is 9.4.
Bang for buck turbo is better than a buildup of your D series, and seeing as you're stuck with the d instead of a b..

Um, as for shopping list.

Things you will need,

Injectors - 550 CC
ECU - as i said before, uberdata is cheap but finding someone that knows their stuff, I dunno about the UK, but its difficult here? Maybe a Hondata unit would be more to your needs?
TurboKit. Depends on your power goals. And your budget. You could get an off the shelf one, but you don't see many "built by e-bay" cars out there (jdmcivic.com thanks for that). Seriously, stay away from companies like Stone Mountain / SS AutoChrome. Stick to proven trusted brands, Garrett, IHI, HKS (rebadged garrett with diff trim wheels) Full-Race (for honda woot woot) RevHard, Turbonetics, A'PEXi use IHI turbos in their applications.

Also make sure you got your power goals too.
Its all well and good to say, I wanna make, like "250+ at the wheels" but, im betting that there's a time down the line where your 250 just wont cut it, and you might do a rebuild, and get say, 300+... so make sure you build to upgrade. Eventually something is going to blow right? Over a long enough time frame everything dies.

Fuel pump, tricky, depends on your HP goals, It hink that if you are going to do this, might as well get a fuel pump, and do it right the first time, and probably change your fuel filter while you are at it, because, if it hasnt been changed for a while, you'll notice some difference on that end too.

Don't forget little things like oil cooling and maybe running with a lower temp thermostat. When you make more power you're going to be making more heat obviously, i guess the UK climate is better than the Aussie one for heat, but you never know, better safe than sorry.

Whether or not to use a wastegate. Some kits come with them, some kits come without them. I guess if you want to run say, 11 lbs of boost, day in day out, everyday, without fear of boost spiking, then its what you want.

Manifold style is probably the most crucial factor in designing your turbo kit apart from the tune. A log style manifold will get you over the line, but where the real power is made is in the manifold design. equal runner / length manifold designs are proven on the dyno to be far superior.

I'm going to try doing my turbo install with my engineer friend when I get back from Indonesia, and the kit I'll be getting is made by Full-Race.com in the USA.

Anyway, hope it helps, and I wasn't long winded, etc etc.

Sorry if I give you crap intel. Im sure someone else on here will say something if I do :D

Also intercoolers seem to fit quite easily for hondas, 600x300 shouldn't be too much of an issue.

Hopefully, its this simple when I get around to do it, but im still aquiring parts.

this is a buildup of a SOHC D series

this is the kit I am looking at buying.
http://www.full-race.com/catalog/product_info.php?cPath=24_143_45&products_id=37

a civic with a b series stock (like mine) ran an 11 with it, with full interior.

[Hath]

cheers buddy :) well could you tell me as much on this kkit then after looking its the first one at the top of the page http://www.turbo-kits.com/92-95_civic_turbo_kits.html turbonetics, along with this i am obviously going to be purchasing a clutch to cope wiht the advers power changes, as far as ecu management is concerend looking into hondata. it is near on impossible to find a mapper ion teh ukk there non existent.. however i literally am looking for lowe power to start with get used to the cosmetics of running.. working a turbo so my understanding becomes better and more knowledgable when it comes to me melting something,or brekaing something..:) am literally looking for just 225 bhp whihc should be easily achievable at 7 psi. injectors come wiht the kit mentioned above.. fulel pump wise was looking at a walbro 255lph.. im under the impression this will be man enough.?

[Luc]

yeah but there's parts in that kit for that price that you really dont need.

like 2 bar map sensor.

stock map sensor will read what you need easily.

440cc's arent big enough
its using an injector controller. your hondata would do that.

look, I gotta go to sleep cuz I have work in 6 hrs, but im sure that some other honda boys can tell you pros/ cons. its 5am here hehe

[project2]

yeah but there's parts in that kit for that price that you really dont need.

like 2 bar map sensor.

stock map sensor will read what you need easily.

Stock Map sensor only reads upto 14psi. Keep in mind motors already runs some 14Psi Atmo If I remember correctly.. IF you plan to run more then 14psi get a 3 BAR sensor which is good for about 20-25psi

[Luc]

you're kinda right project2, but atmosphere at sea level is 14.7 psi, that is, when you are at sea level, there is already 14.7 psi on your skin. This is a measurement of the mass of the air weighing down on your skin, this means that because the entire world isn't at sea level, there is a variation depending on altitude.

3 bar = 44 psi approx.

Motors that are N/A are vacuum motors, meaning, that they suck air in. there is no way that you can create positive pressure in an intake manifold without either a super / turbocharger.

Look, im not saying that there can be similar effects to FI, like the Helmholtz effect. But that is not true fi.

When air is forced into a cavity, the pressure inside increases. Once the external force that forces the air into the cavity disappears, the higher-pressure air inside will flow out. However, this surge of air flowing out will tend to over-compensate, and the cavity will be left at a pressure slightly lower than the outside, causing air to be drawn back in. This process repeats with the magnitude of the pressure changes decreasing each time.

Anyway, back on topic.

Dont need a 3 bar map sensor as you won't be running 44 lbs of boost, you can use the stock one for the moment. :D

550cc injectors because if you wanna build the motor later, its just something that you wont need to buy again.

T3/T4 turbo hybrid is ok, should be responsive enough, but give you enough power. But you gotta figure out what your power goals are for now and maybe down in the future. I think that manifold design should be your biggest concern for now as thats what forms the foundation for your power. So try and find an equal-length style manifold that will give your turbo better spool characteristics.

Plus, a bit of lag isnt all that bad cuz you dont wanna run around on boost all day.

And thats about it.

[Hath]

okie then cheers for the info now i dont mean to be a silly guy about this i do want a great deal of "SAFE" power running low boost. ok granted as im am turboeing it im going to be looking at extra power but with costs of petrol over here quite high i wanna keep boost to a minimum lol what i am after is everything i need for the turbo conversion.. if anyone wiht the right technical mind could point me at everything i need please do so.. so i havea vague idea i mean this is the second kit ive looked at id rather do it right and get a price in my head and know what to buy than buy a gathering of crap and make my engine do the funky chicken before blowing up.. maybe someone could post me a shopping list? wiht links to prices etc.. would be more than gratefull

[Luc]

can you pm me your email address, and i'll get someone more knowledgeable to answer your question and give you a vague idea on parts.
