im currently fitting my new engine into my rs500.it was standard before but the engine going into it has the following;
200 long studded block
knife edged crank
multilayer head gasket
head ported to wrc spec
double valve springs
bd10 cams with verniers.
bronze guides

now it used to be in my old sapphire running 8 green injectors on wrc manifold on p8 ecu with anti lag and nitrous.ive sold the manifold,p8 etc as i was looking to either go with 4 greys or utilise the rs500 manifold and go 8 greens.

can the original ecu be modded to run the 8 injectors or do i need to get another ecu.if so which one and does anyone know of any for sale.i contacted mike rainbird about his p8 but he isnt selling it yet.
i have got a standard l8 ecu knocking about-could that be used?i missed a super 8 set up with loom and boost pot on ebay at xmas

or does anyone reccomend another route ie,4 x greys live mapped or any other ideas.
im a bit stuck now and want to get the car finished soon.

any help/ideas would be greatly appreciated.
it is an rs500 so i have the t4 and 8 injector manifold.i also have 8 green injectors and 4 greys knocking about.

please help as this will probably get my arse in gear to finish it off.

thanks in advance guys

 

You could have the L8 modded into a super 8 or mega 8 (Collins) to run 8 injectors...

Or you could have the L8 mapped at MSD or NMS on the greys or even larger injectors..... I think MSD keep 550cc (greys are 503 IIRC) and 830cc injectors in stock.

 

autronic and 4 1000cc injectors

my injectors are 70% maxed at 7k... thats more fuel than 8 greens

 

any idea of prices of the modding of the ecu

 

does anyone know of anyone selling an ecu already converted for 8 injectors?

 

Yes,
ive got one ! I haven't a clue what its worth tho and as i need £2k for the T6 thats going in my car so i wont be giving it away .
Its a P8 , super 8 injectors activated , ALS enabled and freshly mapped for my 7.2 Race engine with 2 chips by julian godfrey in November last year , 1 x 103 elf fuel chip and an optimax chip !
Ryan Pestell has the loom as it needed 2 bits of braid replaced and im still waiting to get it back !!!

 

hello tony,the one on ebay at xmas was p8 converted to super 8 c/w 12 position boost pot and loom and it went for £650

mike rainbird wants £725 for his p8 set up but isnt selling for at least a few months.

any rough ideas what you want for it and when you will be getting the loom back............
im very interested at the right price

thanks jay

 

A year back i paid 800 for a p8 super 8 anti lag ecu.

If you had to do it from a stock ECU...

P8= 350
Sub loom= 50
Super 8 conversion= 600
Anti Lag= 300

Almost worth goin Autronic if you was doin it that way

 

Thats about how i value it , you do see them come up for sale sometimes but when ive needed one before after all the mods theyre well over a grand !
the loom isn't a mickey mouse sub -loom its a full Pectel 8 injector loom , again quite rare to find , even tho some people make them from scratch i hear . Not sure when im getting it back , if Ryan ses this hopefully he'll repsond and sort it out .

 

I would go for the Collins ECU with the 8 injector capability, water injection, water spray, anti lag, launch control, shift light, distributorless ignition, and its faster than a Weber marelli P8 ECU

decisions,decisions

anyone used the collins ecu on their car?
i have spoken to them about it and can get a good deal on it,which i had actually forgot about

 

looks like im going to be spending some money,not cheap these big set ups

 

back to top

 

L8, 4 big injectors, closed loop... job done, minimum outlay.

 

You no it makes sense Jay, as you will only sell it after a few weeks

 

i like the sound of that stu....
what size injectors would you recommend.i have a l8 ecu coming this week.

any ideas on the cost and when you would be able to do it.the engine isnt in the car yet so no rush.

 

Correct Injector choice depends on expected horsepower output and rated fuel pressure. If sticking with the T4 you can easily get away with a set of 85lbph injectors.

Cost to map is £500
Airinjector driver adds £100
Closed loop adds an additional £270

Time to complete is 1 full week (Sat - sat ideally) Currently booking April.

 

sorry to sound daft but which injectors are they?

 

Siemens. Black in colour (As if you care..)

 

of course i care,the engine bay is going to be black and chrome!how much are they for 4?

 

IIRC they where a very similar price to the Bosch type injectors (60/70 ish an injector).

 

cool,do you have them on the shelf stu?

 

jay you still got the old ybd out of the car ??

 

jay ill dig out the guys email address i sold the p8 setup to, as i know his escoss is on ebay at the min so he wont be needing the stuff he bought from me

 

hi darren,yes ive still got the old engine.
