Project MUGEN Civic Type R

OK i finally got my car back this arvo.
It was put on the dyno and the poor thing is starving of fuel with the B16 fuel rail and injectors so now the next step is to go get some ITR ones.
The check engine light is on constantly so we'll have to see whats up with that ?

Apart from that, it has some good pulling power but i didnt go above 5000rpm. Hence im not allowed to if the engine is running lean. I cant wait to take it 9300 - where it should be. It was tuned with the B16 injectors and still produced a lot more than the B16 ever did at each rpm (well i bloody hopeso) but it will be fully tuned when these ITR injectors arrive :)

have one set of ITR injectors, 180

b16a -b18c7 same size injectors 240cc saturated... try and find a 92-96 prelude vtec they have 345cc injectors peak n hold...good luck dude :thumbsup:

Then you'd need a resistor pack

whats this resistor pack ???

u need a resistor pack to run prelude injectors cos they are diff from B series ones

suggest u get fuel reg, up the press, get bigger fuel pump, unless u already done it

Injectors come in two main types (in terms of electrical) - hi resistance and low resistance. I think B series injectors are hi resistance and prelude ones are low resistance (someone correct me if I'm wrong). Therefore you'll need a resistor pack to change the resistance to match the injectors.

Also, there's injectors out there that flow differently - some are peak and hold while otheres are intermittant; also spray patterns can be different.

There's alot to consider, and injectors from different cars from the same manufacturer may vary sometimes as well.

So just keep these issues in mind. But most of the time, it's ok.

OBDI injectors are Low impedence and OBDII injectors are high impedence

well u just watsed a tune if ur running lean :/ get something decent in there - rc 440cc injectors go for realitvily cheap ~200USD on ebay and will deal with all ur fuel needs. DOnt waste money on regulators and rails, ur stock should be able to flow alot more HP then u will make. They are drop in, no ressiter packs needed. WHat kind of managment do u have? i thought u had a 'mugan' race ecu or something? or are u running a remapper like uberdata?

This is just ignorant. Stop listening to these people who obviously have no experience at all.
DOnt bother with standard honda, im sure the prelude injectors will cost just as much as any aftermarket brand, which will outspray them 2-to-1.

no i havent already done it Andrew ...
the mugen ECU is trying to pump more fuel into the engine but this is limited to the injectors. Atm the tuner has woulnd back the tuning to cater for what i have and he said there is a truckload of power im losing out on - if u know what i mean.
Can u run these prelude injectors without this resistor pack, fpr and pump ?

as soon as u increase the size of the injectors, u will double or increase the fuel injected along the whole rev range. Do u get what i mean? Your ecu will still think it has 240cc injectors and will pump the fuel in at the same rate. You need a way to trim ur MAP's back in line with the changes. Is ur mugen ecu able to be programed? I dont get what ur managment is! How DOES he tune ur car?
The honda fuel system is able to take plenty of HP. over 300hp+ people have goten without even upgrading the pump. You dont need ANYTHING accept injectors. A resister pack - if u decide to go down the road of peak and hold injectors - can be found on any DSM trading forum. They go for dirt cheap - 10-20usd max. but i wouldnt bother, unless u get the injectors for free. AS i said, RC are leaders in injection, and they ar cheap!
