will l8 run 8 injector set up?

rapidcossie

dont think so.

Depends who you talk to though My rs500 block cracked at 430bhp, when i went to drop my engine off at the shop they had a 200 in stage3 power that had cracked all the way down 1 side so its luck of the draw imo

Dingy

So what your saying is if you use a L6 you aint done it right cause you can't control it ?

rapidcossie

Can you control L6?

map it etc?

l8 will run 8 inj but it has to be moded by pectel

there has been more cracked 200 block threads on here lately then anything else lol imo if built right on either block it will be ok

Dingy

Nope but then i can't map a l8, P8 l1 etc either

tbh i spoke to karl about doing my car and he is the only person willing to map my car with the t4 and 83lb siemens injectors still on l6 ecu

200 block
ported head
cams
750cc injectors
l8
t4 turbo
std piston low comp
doble valve spring
o ring the block or 4 layer mountune head gasket cometic dont last long with that power i tried it and it didnt hold for long now on 4 layer and going strong
small turbo inlet
long stud it ...not the crap arp stud and nut kit it cracks the block on the head bolts or std head bolts mine is holding with them 2.3 bar should see you what you want hope this helps

fookin hell!

this is confusing!

stop quoting everything!!

I'm going for a 500ish figure but i want it done right and I think i'm doing it with the right people!!!

(I think I am from numerous visits, and a certain fast cossie is currently parked next to mine at the place!- leave the experts to the details!!!)

Cheers for that, what is the problem with the stud and nut kits??????
Shurely its sort of the same principal as standard bolts in the respect it screws into the same holes anh tightens the head down????????

you can map any ECU from L1 to P8 to EEC IV. The difference is the amount of Mapping sites availiable and the speed of the processor....... Obviously a L8 will give a higher resolution, and now has more features avaliable such as closed loop lambda control, ALS/ LC/ wasted spark etc etc, but you can still modify a L6 to 8 injector spec.

All of the L series ECU's can be live mapped, I belive it is only the P8 you cannot live map if it has a pectel board fitted....

500BHP+ is achiveable on any of the webber ECU's AFAIK, but obviosly L8 wil be much better than L1 due to it having 4 times as many load sites to map

they screw down in the same place of the std head bolt hole .weak spot any ways and you have just incresed the force in that area so most of the times they crack accros the bolt hole so as the nut and stud can apply more force .plus the std head bolts stretch were as the arp dont in the same way not 100% tho

Alps Pacino

What i was getting at was i thought the arp studs were only torqued down the same as standard bolts, so same stress if you see what i mean

cossiemanden

To be honest, i have never heard of this problem before, and i have cracked one block with std head bolts and my new engine and the one before use arp without a problem.
also the 750+bhp cossie in sweeden use arp without any problems.
90% of the cossie in denmark use arp, all works fine

your right m8 they are running the long stud and nut the type that need maching to fit i am on about the ones that screw down in the normal head bolt place

rapidcossie

where is the "white " reply dingy

cossiemanden

Yep stian is but fredde and conny is the "normal" arp set, mine also, my friends Green MK2 escort with 752bhp is also std arp not the long type.
But it helps if you mod the block just enough so that you get the studs down the last few milimeters of the thread then it will help a lot

White / Black WTF

iTrader: (1)

this one is the short standerd replacement that i belive cracks the blocks


this ones are they correct long stud that i am on about

c0ss1e9i6

ohh fookin hell!

now i'm confused proper!!

abdr500

iTrader: (1)

i geuss its they way people fit them to as some people will fit the stud in with grips and some will do them up hand tight and then let the nut and the stud do the torque as both will be able to turn

iTrader: (4)

I have the later..

rapidcossie

Was having a wee joke with dingy as earlier in the thread he seem to just say the complete opposite of what I was

Gotya

cossiemanden

Ecatly.
I have always used a thread cutter to get the arp`s to the buttom of the block thread, and then hand tighten as much i can, no grippers or anything.
Also what states in the papers that come with the arp i think

NMS Badboy^NUTTER^

I have used long studs and 200 block without success.

I now use a 205 block and std head bolts without a problem

Alps Pacino

^NUTTER^

Spanner and works lol

I'm just going to arp stud and nut, 205 block and cometic gasket. I know its not the "best" combination but judging by this thread there is no such thing as everything seems to fuck the block weather it be long stud o standard 205 or 200 it dont matter there all shit lol

why not use std head bolts thers no reson for you to use any thing else i have 511 bhp and use a 4 layer and std head bolts with out a problem

costina

iTrader: (1)

The reason why long studs don't crack the block is simple when machined they have a counterbore in the top then the theads and there longer

Alps Pacino

Costina and i quote lol

abdr500

iTrader: (1)

yea but that was his own experince many tunners will advise on the long stud at that level as most seem to give good feed back on this set up

Alps Pacino

abdr500

Agreed but its luck of the draw surely, what i'm trying to say is long studding doesnt cure the block cracking issue as many people on here would suggest

abdr500

iTrader: (1)

Alps Pacino
i think you will find that it will solve that problem of cracking i dont no any were else the 200 blocks crack my be in the bore area but that could happen to any blocks just bad luck realy

DANNY-B

nobodys mentioned the most important thing you need to put 500bhp through the wheels.......................GIANT BALLS OF STEEL, lol

iTrader: (5)

205 block will be fine imo!!i would use standard head bolts tho

RWD_cossie_wil

205 blocks crack across the bolt holes, long studs don't. ARP stud and nut kits cost just under half of getting a propper logn stud job done why take the chance??? Please don't skimp on a 500BHP engine build, it will cost you 4 times as much in the long run, I promise you.....

There is always an exception to the rule, such as nutters, but WHY do you think COSWORTH made an updated RS 500 block and a thicker 200 block? they didn't do it for shits and giggles did they?

again, take it from someone who knows, build it once, build it right...

I can't remember who said it, but to quote a famous quote :

" it is better to spend a little too much, and to have perfection, than spend too little and find that what you have is totally unsuitable for its purpose and will cost you much more than you have first saved in putting it right, time and heartache "
