I will start with what I have got/had done

rebuild on 13bt with lower compression rotors
large street porting done
full to4 60-1 - .70/1.05
trust front mount intercooler
microtech ltx8
2 x 1000cc injectors
bosch 500hp rated fuel pump

can I use the stock fuel pressure regulator ?

should I go with 1000cc injectors all round ?

I am wanting around 370RWHP

thankyou

I would get an aftermarket fpr just for the simple fact that its adjusatble, easy to put a guage inline and the fact that its not 15+years old.

I would recomend going with some more injector be it in the primary or secondary spot.

Although how big you goin the primary spot is entirely up to you, i wouldnt go any bigger than a 850cc or so just because those are the biggest that i have heard of people idling on at a semi normal rpm. Any bigger than that and you probably will have a hard time getting a smooth idle.

 

will I need an aftermarket fuel rail ?

can I use 3rd gen injectors as primary ?

and by using smaller primarys will I need to go with larger secodarys ?

thankyou

I just used a s4 rail so i could get screw in fittings and what not. I dont know at what level aftermarket rails are recomended and or required.

3rd gens use side feed injectors so unless you wanna do alot of modifying then i wouldnt recomend them.

Here is the fuel calculator i use to get a general idea. http://www.maxcooper.com/rx7/how-to/...tem/calcs.html

 

hi crusader

is there any chance you could mail me some pictures of your fuel setup so I can get a general idea as I cannot seem to find any ?

jey@jeysrx7.co.uk

thankyou

i made 372 rwhp with 550 primaries and 1000 secondies.
t2 fuel rail that i welded the fittings on to accept 8AN fittings for both.
dont go with the 3rd gen injectors as the hole where the injector sits in the block is much bigger than the ts hole.

 

Here is a link to my album. I dont really have any clear fuel setup shoots but if you know what to look for you should be able to see it. Also these are some older pics of my car, i will be changing things around under there.

Edit: forgot the link lol. http://www.freepichosting.com/Albums/421577410.html

 

thankyou very much crusader - just what I needed

sorry to be a pest but -

what size intercooler piping are you using ?

have you modified the coils/ignition at all ?

have you done the throttle body mod ?

how much power are you making ?

thanks again

jeyjey

 

Turbo to intercooler is 2.5 and intercooler to motor is 3.

Whenever all the payments on the new microtech gb go through i will have a new lt10xs on the way with a x4 ignition box and 4 bosch coils.

I have removed all the unecesary stuff from the throttle body yes but no to porting or anything.

Dunno on that one.
