ok here is the deal i want to find a way just to get rid of my fuel cut. i am not looking to run crazy boost for now i just want to run the car and now worry about the fuel cut off, now i am hearing so many different things to do. one is get the rtec 1.7. that requires changing the injectors to 720cc. i have the 720cc injectors but i am really way to scared to mess with the motor like that. i just got the car three weeks ago and i don't want to mess anything up! and there is no one around here that has an rx7 to help me or to show me how to do it! second option get the rtec 1.5 and not have to change my injectors! i am leaning towards that! and then the last option i was told this is my best option and that is getting a fcd and a safc and that is the best way to go! but i like the rtec 1.5 because of the whole retard of the timing and the fact that it gives me the fcd. what would you guys do? the mods that i have done to my fc is a turbo back exhaust (so i was told by the guy i got it from) it is street ported, and a k&n filter hks bov and that is it so far! what should i do?

 

I'd get the RTEC 1.7.

 

ok i see your in nyc want to give a brotha a hand on the injectors?

 

Not in NY at the moment, it's actually not all too bad. You can just remove the top mount, unbolt the upper intake, and you can probably even leave everything connected to it, just move it up and away from the lower intake, and tada, there are your injectors!

 

easier said then done! i am just really scared of doing it if i had someone give me guide line i mean be right there with me while i do it i would go with the 1.7 but i don't have anyone close enough to me to give me a hand and say here you go this is how we do it!

 

lol, actually, I think this is one of those things that's easier done than said, it's probably the easiest thing to do to a rotary.

 

so i keep hearing just got to understand i am the one that builds honda motor and this is totally new to me i have never even had a rwd car before my 7! but i am learning just for now i want to keep the car running and running right! i know when i get to someone to do the injectors with me i am going to crack up laughing because it was so easy but i just need someone to kind of hold my hand and say ok now that you got this you need to check this this and that then do this and your done!

 

I have a Rtek 1.7 and it runs rich as crap, Im gonna get a SAFC to fine tune it. I like the Rtek seems to work good. send the ECU to them they install it and its plug and play, they have really good customer service. and also if you just do 720's and a FCD it will be extreamly rich.

 

You say you have a turbo back and a street port, so I would go for the Rtek 1.7 and 720cc secondaries if at all possible. Otherwise you'll be running too lean under boost, which means there's a good chance of blowing the motor.

The Rtek swap itself is a cakewalk, from what SonicRat says installing the injectors should be pretty simple (never done it myself). If you didn't have the turbo back I'd say just go for the 1.5, but with that open exhaust you'll need more fuel.

 

you i look under my car and i don't think the thing is turbo back i think it is a cat back because there is a new cat there! and on the paper work the dude gave me it doesn't say cat back it just says cat and exhaust install so it just might be cat back

 

If it's just a cat back you should probably be OK with the 1.5.
If you want to go for more power later you can always upgrade to the 1.7 and add 720's.

The RB turbo back has a presilencer instead of a cat, it looks like this: http://www.racingbeat.com/resultset....tNumber=16425P

 

nope it is a cat and then a nice 3 inch pipe all the way to the n1 exhaust

 

how much boost you running, are you hitting fuel cut now???

 

Trust me, swapping injectors is a cakewalk. Nothing hard about doing it other than getting off of the pc and walking out to your car. Just mark where the smaller hoses go and make a small diagram. The main thing that is scaring you im sure is the TMIC, which is not a problem at all.

 

well this may help your decision i was just on pokketlogger annd they dont even list the 1.5 anymore because noone was buying it

 

Swapping injectors is as easy as it comes on rotaries, sort of. You just need to get a new UIM gasket. Its not hard. If you only have a cat-back exhaust then you shouldnt hit fuel cut. Pop the hood and see if the downpipe is stock. I did the injector swap within 2 hours once I got all of the parts. There is almost no way you can mess it up, unless you take off the vac lines, which you dont have to do. I only did it to sandblast the UIM( Looks sweet!)

 

NO WAY MAN, i filled my bitch up with gas yesterday and that **** was EASY!

 

Mepmepmepmep. Oh, VEry FUnny.

 

I had an rtek 1.7 in my car when it was sold - it worked well and was pretty conservative. I ran a max of 13 psi (creep) and the car was still pretty rich. Secondary injection was super smooth and the fllod clear/timing control were great features. I'd wait until they release their next round of ECU's - they will offer a great deal of adjustability.

 

If you just lift the UIM and leave everything connected it'll be pretty easy (except for big hands I guess). But if you pull the UIM out completely, it may get a bit annoying. I hate that coolant hose on the bottom of the UIM though..... Freaking annoying to get the clamp on it.... I had to replace the PD recently and when I do injectors, I'm just gonna try leaving the UIM mostly hooked up.

The intercooler is real easy to get off though, don't worry about that, just don't let junk fall in your intake or anything

 

i think it was like 7-10 bolts or something like that to remove the intercooler UIM and put the new injectors in its is REALLLLLLY simple and straight forward

 

Like everyone else is saying, it's easy as can be to change injectors on a 7, especially if you're bareblock Just make sure you lube the new o-rings with motor oil off of your dipstick to lubricate them so they don't tear.

 

Come on man, it's not too tough. Definetly go with the 1.7. You didn't tell me the engine was streetported! your best bet is to go with the 1.7 and and safc to play with the a/f mixture.

 

For the cost of an RTEK and SAFC, you're approaching the price of a used standalone..

 

wait you can get an safc for 180 used and an rtek for 125 so you are saying that is close to standalone?
