Nice injectors mateI wish I had brought these
Could you have some sort of fuel cut off in the car, switch or a mechanical tap of some sort?
Its just the way the hose fits to the adaptors, pain to fit and im just amazed to what pressure they state they will take, just seems like the hose could pull out. Ok ive put them in a vise and tried to pull them out which i cant do, but i cant load them up to 100psi + or so which i guess we will be at.. Ill find out soon.. All my fittings are fast flow design joins, not swivel style...
It's normal to return the fuel to the collector (the downside being heating the fuel), but, the lift pump should have more flow than the injectors, after all it has to be able to catch up after sucking air. But then I guess you're not on full throttle for longOriginally Posted by Scoff
Yeah, it's staggering how much fuel 2 of those can move. Mine will empty my 2L swirl pot in not many seconds. Even regulated at 3 bar they will suck the pot dry with the lift pump (the usual uprated GTT type) running flat out to fill it. I have to run the rail return to the swirl pot to keep the level up. A leak, anywhere in the bay would be game over.. My system is only spec'd at 2L/min @7 bar so it's easy for me. You should see the lift pumps we make at work, I even have a mini dyno on my desk for motor power/efficiency curves
How do you mean fast flow? Did you buy them from torques?
exactly why we chose to make a new tank and gravity feed the pump direct, seemed complicated and too much to go wrong with a lift pump and surge tank setup, we was worried about the lift pump keeping up, or 1 of 3 pumps failing.It's normal to return the fuel to the collector (the downside being heating the fuel), but, the lift pump should have more flow than the injectors, after all it has to be able to catch up after sucking air.

simplest way is usually the best way
Yes from Torques, fast flow doesnt mean it will flow more, there the same bores just different fitment, take a look on ebay at there shop..
tank nearly done..
Yay the other gate is here.. getting closer to a run...
Not to be a downer or anything but your gunna make bugger all power with such a small turbo
Looking good Rob, not far off now mate
More honda spammmmmm......
Looks like you had a nose bleed while you were fitting the injectors
Nice mate
Awesome, cant wait to see it in action
Nearly there now.. a little bit of weighting tonight before i dash of to Oulton Park for the weekend with work.. hoping to be on dyno early next week..
This is the car on its own...
With me in it before set up..
And the nearly finished result, need more balist yet and tweeks..
Looking good! Should hopefully be along to watch this event, if the weather holds out
All ready for the weekend, Car made 531hp @ 19-20psi boost.. leaving the tune there for now, Power is still climbing at 9k rpm but we are only going to rev to 9k at mo and let the motor run in a little... Im not after breaking records at the weekend or chassing Scoff just yet.. I just want to beat our old time but with not much effert..
Cheers for anyone thats helped or followed this thread..
Nice one mate, im coming up with the missus to watch on sunday cant wait to see how this goes
good idea to break it in gently
9K... That's where Scoff will struggle, what's the stroke on your engine?

9K... That's where Scoff will struggle, what's the stroke on your engine?
that was gentle
87.2mm stroke our motor, 83mm bore.
it carries torque fantastic, only dropped 20lb/ft at 9k from peak, hp was still climbing at the rev limit. standard cams too
the 1.00 a/r t4 turbine needs a few revs to get it going mind
You got me a little worried now Rob although i'm using the smaller unit BG S200SX twin scroll with 1.0 a/r.that was gentle
the 1.00 a/r t4 turbine needs a few revs to get it going mind
I hope it's not going to be too laggy.
Wups sorry, I mean its a 1.1 housing..
Ah thats better. How 'laggy' is it Rob? Would it be unbearable on the road?
That's awesome! I love the way it just goes mental when it comes on boost!
I think it's going to be 6.5krpm + before it does anything worth talking about Matt !
Someone needs a bigger dyno
Glad it's getting there
post the plot or I'm calling BS
so if Matt keeps the standard rev limiter he'll be able to get rid of the intercooler
..and use a 1 bar map sensorso if Matt keeps the standard rev limiter he'll be able to get rid of the intercooler
Lets hope you have more luck this weekend than this guy:

Ha you guys!..and use a 1 bar map sensor
Not wishing to spam Rob's thread, but these Borg Warners seem to spool reasonably well for the size of them or so iv'e read/been told. They seem to be piopular with the Evo crowd, desperate to get away from laggy manufacturers turbos. If my thoughts are correct (very rarely) i would hope to have 1 bar by 3500 and max boost by possibly 4500? Thats with a 1.0 a/r divided backend. This i could live with and i guess all depends on getting enough revs.
Im very interested on how Rob's turbo performs and when it gets on full boost?
Matt, which BW do you have ? I get 1 bar by about 5500rpm. Thats with a "little" 0.82ar T3 housing.
Scoff,
Here's a link and info to mine:

Rob has it's big brother, i guess another animal entirely.
Ah, not at all the turbo I had in mind. I take that back then, I think it should work fine.

Just spent nearly an hour reading this thread again, much going on with it now?
Also did I read that you ended up using the standard size vitara pistons in the over bored block? Still so tempting to do. Could pull 12s on the quarter for next to nothing
well we went 10.6@137mph at the outlaw race, which was the cars 1st outing on the new engine.
weve not had it out since, it needs some upgrades, we hit 99% duty on the injectors, so need to go bigger, plus the gearbox was dropping too much rpm on the 1-2 shift, we need the integra gearbox, which is closer ratio, we have the civic vti-s 'box' which is poo
as for the D16 motor, we did 2, the first one was overbored and used oversized vitara pistons (75.5mm), but cracked a sleeve later in the year.
the 2nd motor we didnt bother boring (to keep the sleeves as thick as poss) and ran 75.0mm vitara pistons on that one, and never cracked a sleeve, even running really lean when we maxed the pump out and hit 100% injector duty.
i would deff stay standard bore and use standard 75.0mm pistons adey, and 12`s, pah!! it will go low 11`s all day. we ran stock inlet mani which was crap, cast turbo mani, and no where near big enough on the fuel side and went 10.9. id be totally confidant of going 10.5 if i built another d16.
Cheers for the info, just pricing things up, I think most of the cost is in the shipping!
the civiclife forum classifieds would be your best bet mate, lots of parts on there, unfinished projects etc, its a very busy forum your sure to find what you want sooner or later
Rob loves civiclife
lol, not quite! i dont even like jap cars, but you cant argue with the engineering.
Did you hear adam went 9.78 on Sunday ? 2 1/100's behind CPL.
9s PAH, where are the 8s
yeah did hear, noticed it was at the same mph as you
That'll be the "skill", there used to be a guy on here who had "skill"noticed it was at the same mph as you
Civic life, omfg! I forgot how childish some forums can be!Rob loves civiclife
Maybe so, but I'm starting to think that the additional weight in those Honda's is helping a lot in their 330'. I'm confident I could not have gone any quicker in the 330' on Saturday, bar finding some way to speed up the 1-2 shift, yet the 2 Hondas manage to go that bit quicker. If I put in any more power to those gears I would be slipping. I need to stiffen or limit the rear suspension travel too, that might account for something.yeah did hear, noticed it was at the same mph as you
it'll be a combination of weight distribution, wheelbase, and maybe C of G. It's possible that bolting a girder under the front bumper would make you faster. I don't think weight per-se would help unless it flattens the tyres out more?
