R18 Turbo Kit

[1zach4]

Ok well I know we have a poll for this but this thread will be for actual development of a kit as it will probably be up to us, the owners of the R18 civics, to develop the first kits.

I have made two threads over on Honda-tech.com about building a turbo manifold for the R18 and it should be the cheapest manifold to produce in terms of how much time would go into making one and products used because it should simply be a head flange and an intermediate pipe to a turbo flange. We are very lucky in this department, but now we need someone to BUILD this manifold, and we need to get started on looking for some sort of engine management system.

e manage isnt universal????

i think the most "dificult" part is the manifold and piping and find a plce to put everything xD

You'll need more than a manifold...you'll need a head since the manifold is built in the head. It's one piecw.




Civic: Exhaust System

"The Civic is equipped with a stainless steel, low heat-mass exhaust system integrated into the cylinder head that eliminates the need for a separate exhaust manifold, contributing to the engine's compact design and light weight. The system employs a high-density catalytic converter for improved light-off performance and reduced hydrocarbons and NOx. For emissions performance, the exhaust manifold is positioned on the front of the engine-which shortens the distance that the exhaust gases must travel to the catalytic converter, resulting in faster light-off and more complete conversion of the exhaust gases."

just because you're used to turbos connecting to manifold doesn't mean that's the only way.

you would need to attach a housing after the exhaust manifold which lets you attach a turbo.
other than that.. it should be cake from there as far as peicing it together.

Fitting one might be a problem.. at least anything bigger then a T-25

[1zach4]

someone on honda-tech is already developing an adapter for it, so it shouldn't be long.

Honestly if someone would just take the car to a machine shop they could have a flange built in an hour, and then you can attach an external wastegate in there and make a pipe to connect it to a T3/T25/T4 flange and you'd be done.

YOU DO NOT need a new head lol. The manifold is built into the head, but the "header" is connected at a flange into the manifold, so that would be where the flange/adapter comes into play

fitting a turbo might be a problem. Especially anything big though.. unless you can get smaller radiator and cooling fans - or possibly removing one of the fans.

[1zach4]

well the guy on Honda-tech is working towards a full kit right now.

If it doesn't turn out like I want to I may buy his manifold and take it to a local shop and see if they can use it as a base to build a manifold that will support a 3" downpipe and larger turbos such as a GT35R

i'd be perfectly happy with a small turbo. 200whp would kick so much ass!! consider you'll have instant boost from the small turbo.

200whp would be nice.. depending on the price of the kit.. otherwise i'd might want a little more.. or at least be able to do it safely. We'll have to find out how much hp this stock motor can handle.

[Kurt]

i want 240-250 whp

[1zach4]

I know it won't happen right away due to our lack of tuning options @ the moment but I want 350whp @ least...i'm spoiled though because i've ridden in 600+whp hondas and personally owned a 475whp integra

[Kurt]

well i dont have the cash to build the engine.. so im thinking 250whp will be good for daily driving and longevity

[leviathan18]

if my guess is correct the r18 is almost the same engine as the d17 right? well the d17 could handle 80% power increase that is alot.

from dezod site:

Dyno Results: Our AUTO transmission 2001 Civic EX made 90 WHP & 84 WTQ prior to turbo, and after the addition of our turbo kit made 146.7 WHP & 121.9 FT/LBS of WTQ @ circa 8 PSI w/ a T3 Super 60 turbo, on 93 Octane (no additives or sprays & running a fully functional catalytic converter on the down pipe) on a 76 degree day in Buffalo, NY. That is a 63% power increase, and a 45% torque increase at the wheels on a mere 8 PSI on a stock motor, automatic transmission vehicle. 5 Speed vehicles can expect an additional 15-25% more power.

The car has been daily driven and drives like a stock turbo'd car with no idle issues. A/C, P/S & ABS remain untouched as well.

The entire kit requires minimal to no fabrication involved. (The front bumper will have to be cut in some areas for the FMIC to fit properly. The stock fuel rail requires modification for the injectors. The RSX injectors clips plug into the existing harness. The other injector sizes require being wired in. Holes must be drilled into bumper support to mount the FMIC.) This is the most comprehensive kit available on the market. We use all quality components such as Blitz, GReddy, Garrett, Denso, TiAL...Just to name a few.

i'm sure this motor can at least handle 200whp stock and stay reliable. Anything above that, I would probably want to replace the internals with forged pistons and rods.. at least then you could be pushinig 300whp easily.

My GSX had forged internals, bored .020 over. I had the cyl head ported and polished..more so on the exhaust side since turbo's force air in.. no need to polish the intake side as much. After everythign was done, I had it running for about a week then sold the car to some kid.. He's pushing a good 550whp in the eclipse for 30,000 miles no without a single problem. The engine was built to handle at least 700-800whp.

[1zach4]

it's pointless to post up info on the DEZOD kit because this is not a discussion about the DEZOD kit, nor does that kit apply to the R18, it applies to the D17.

We will not know how the R18 reacts to boost until someone does it! So until then we cannot compare it to the D17.

We might be able to use the universal EMS system from AEM.

[1zach4]

you could push 300whp on this motor easily on the stock internals...it is all in the tuning.

yea, everyone want xxxxx amount of power but i'm just being realistic. yea sure i'd rather have a 9999999hp civic but let's get real.

200whp is more realistic with a tiny turbo because of limited room and stock engine than 350hp.

who said they could get 350hp out of a tiny turbo? What I said in my post, 200whp would be fine coming from a small turbo like a T25 maybe.. It might be at its max though. With a T3/T4 hybrid.. you could easily squeeze out 350hp on this engine.. it might be at its max, internals wise.. maybe need at least to rebuild the bottom end.. but it is doable. Not having space isn't really an issue.. they sell thin cooling fans.. you can even remove the A/C one if you really want the power.. Radiators can also be sized thinner too. If people want power, they will find a way to make it..

oops...sorry i didn't even bother to read my own post. because i originally said was.. it is IMPOSSIBLE to get 350hp out of the civic!!!!
