Will FD Injectors Fit A FC ??/

[Brett]

I managed 250 at the flywheel fairly easily on the stock tubby, I reckon you could achieve 270+ with a fully mapped ECU and a bit of WI.
Apexi for the FC is prohibitavley expensive

What boost was you running? I had a go to get some Power from a Stock engine ALONG!!! time ago and i found you don\'t get big power per Psi past 1 bar, its like the Turbo\'s sweet spot is about 12psi.

As an Example i had a To4E on a mild ported Motor proberly not set up the best at 14psi and i could only get just over 270hp, Unfortunatly I poped the Motor just after that so i could\'nt tell you if fitting an Ic etc would have made a diffrence but i was told at the Time the Ic was restricting the Flow and would have to be changed to run any more hp? So read what you will into that?

(BTW my engine failed through a det two weeks after it was set up on a Rollers)

its cheaper than a Microtec.



You could buy an additional inj controller 2nd hand very cheap, get someone to weld you an inj boss on your inlet and away you go.  Stick an 040 pump in the tank for extra fuel, big exhaust and a reasonable intercooler and you could be somewhere near 300 at the fly.

or

Big turbo, ported engine, big injectors, power FC & u could see 378 RWHP

I think when it comes to building a Powerfull car within a Budget you have to do as much of the work/fab yourself to keep Labour down. Thats where all your money goes if your not carfull.

Just do your Home work there is lots of people out there with lots of diffrent ways of making this sort of Power just pick the one that suits you the best and go for it.

But you have to think for example i wanted 300hp you may be able to do it on a Stock turbo and a Small FMIC but what would happen if you wanted 300rwhp you would have to change the Turbo and the IC if you get what i mean, decided on a HP and stick to it thats the secret to Budget Tuning. I had this problem where i bought lots of bits for BIG power and then decided i did\'nt want it that powerfull so i down tuned it and becouse of the size of turbo/IC etc it spoiled the way the car drove. So its swings and roundabouts.

\'ADVISE\' -- \'Performance & Cheap\' - is like trying to mix oil & water!

 Forget it, you are asking for trouble, you will end up spending more when it ends in tears!  :Nono!

[Brett]

It all depends how much power you are looking for as to wether or not its possible within a budget, I agree that you wont see huge figures without buying the appropriate kit.
 IIRC my TII was running around 1bar, peak power at 6250rpm was 248bhp (corrected) 196bhp (atw), 246ftlb.  That was on the stock ECU, I changed to a mapped ECU shortly after that.
 Its this that makes me belive that 300FWHP is possible from the stock setup, my power was deffo being killed by heatsoak, so I think some WI would deffo give some improoved results.  (I did 3 runs, power dropped by over 25bhp and the car was already hot when it went on there so it may have been producing 5-10hp more on a cold run)

 Anyway, to sum up, FD injectors dont fit :p

[Brett]

In terms of ECU cost, a 2nd hand Apexi is normally about £400 more than a 2nd hand Micro\'  (Going via Ebay and the ads in various forums)

[antnicuk]

i have never seen a 2nd hand microtec for sale for an rx7,  i looked into both in quite a lot of detail.  I paid 400 for a new apexi and a new micro tec was 800.

[Brett]

Really?!?  Last Apexi I saw for sale for an FC was over $1800 (USD)

Either way, both are well outside the £50 limit for grinder

[grinder]

what have i started ... Ekkk

hummmmmm looks like this could be a none starter then ... shame as i had plans

i didnt realise it was SOOOOOOOOOOOOO hard to squeeze power out of an FC

just to see if i can sort this thread out .. should be fun

1 - i have seen Microtechs for about $800 mark ( thats AUS dollar so under £400 GBP ) - OK apexi is cheaper - but how much to fit the thing and how much damage do you do to the wiring ?

2 - chris - you MIGHT have the manifold and turbo - so what else would i need ? - i take it that i would need a microtech to run all this and bigger injectors ?

3 - if its sooo hard to get power out of an FC - why are sooo many people trying to do it ( ant , trex etc.. )

4 - yeah chris - i should have bought your injectors , microtech etc...

5 - when i said that i can remove and sell stuff - thats prob when the car is destined for the big garage in the sky !! LOL

hummmm well thats pretty much cover what i was thinking

feel all sad now ... too many hurdles for the simpliest of things

Maybe the FD is the way forward - but i have to buy and then buy bits for it - i already have the FC sat here

like i said - still surprised that you cant get 250 RW-BHP out of an FC without spending £10000000000000000

Stu ...going to bed now and sulking

[Grizzly]

I\'m just a little Puzzled? Getting power int that hard. But you can ask anyone thats done it, its not cheap. It don\'t matter is you are tunning a Mini or a 911 its going to lighten your pocket.

[grinder]

its OK chris - i know that it will lighten my pockets - thats not a real problem to be honest - its just the amount that it lightens them

im trying to work out the best steps in what to do

do you put the microtech on first - just so that you can add more stuff after or what

thats why the injector thread started .. im in no rush for them - just bouncing idea\'s around

im intregued with your tubbie and manifold though

[TRex]

Stu, big numbers mean nothing.  
90% of people on here rave on about their power dyno figures etc.. and to back this up on the strips or tracks they show nothing!
 Sad but true, there is a chap on here with the best signature ever, \'some people race dynos, some race cars\'...(something along these lines).

 I\'ll give you an example from my own experiences, at RS last year I had my car on the dyno for fine tunning a week before, we were messing about and squeezed a max total of (I believe) 378bhp out and printed it(naturally), the car was not safe to drive in this condition, well you could of but I won\'t feel right as this was on the max safe limits.

 We tunned the car down to near 300bhp, yes only 300bhp(all hub readings), and guess what, the car hit 12\'s on the 1/4 on it\'s first set of runs out!  And on big heavy 18 inch wheels with 35 series tyres etc...  

 Couple of weeks later I went for broke and cranked it up again to the big numbers... guess what, I done 11\'s, but the engine did not last!

 It\'s not always about big power and big numbers.

 
 Oh, and my FC had serious dosh spent on it, no corners were cut there!

 Remember \'Quality is better than Quantity\'..  

 Good Luck

Well, speaking to one or two people in the know, you can increase fuel flow through the standard injectors using an FPR (fuel pressure regulator), the standard 550s will run more fuel. in the long run though you\'ll need injectors, pump and FPR. (I\'m in the same situation now!) I have found some 1000cc top feed inj for a very nice "Grinder Friendly" price, but the do need a tiny bit of modification on the fuel rail (nothing serious). 1600s may be a bit too much and the step from 550 primaries to 1600s could be a little difficult to map. I\'ve been advised by a couple of tuners in Aus to go for 1000s all round (they use that setup on their 9 second FC so who am I to argue?)

[sadgoth]

I would suggest putting the microtech on early in the process as you can then map for each mod as you do it. FMIC in itself isn\'t too expensive, the pipework and fitting is the issue, depends on how good you are with your hands!
