Just wondered what was needed on top of my current spec to break the 500bhp barier

205 block with wrc pistons 7.4-1 comp fully lightened and balanced
bd14's with uprated spring
ported and polished head with 3 angle valves and seats
High pressure oil pump
arp stud and nut kit
cometic head gasket
arp rod, flywheel and main bolts
helix 5 puk
Genuine 500 cooler
t4
greys
3 bar
l6 ecu
uprated breather system

 

ditch the greys

 

siemens 83lb injectors and a decent inlet plenum and possibly a l8

 

for what though????

Thats what i'm asking i know there not up for the job but is a 2wd inlet manifold also capable of 500bhp???????????? And i there any other bits of my spec that aint suitable for 500bhp

 

money

 

Small escos inlet manifold

Steve.

 

Diamonds

Thats not a problem

 

cossie4i

Does the 2wd throttle body and stuff fit onto it though?????????

 

Deffo ditch the greys.
go for 2wd exh. manifold
Would`nt think about witch inlet manifold, but would use a plenumspacer for it
go for it

 

can i move in

 

cossiemanden

Its a 3 door so has 2wd manifold, also i think i might try the spacer plate on 2wd inlet and see how i get on tbh.

 

Missed that
Increasing the volume gives better high rpm power, so good idea

 

cossiemanden

But will it acheive 500bhp plus? cause i thought it was the elbow that was restrictive???????

 

That depends on how good your guy that does the porting, if he can match it up fine against the plenum, then no problem
It actualy isent that bad

 

As covered by others you will need new injectors along with a different inlet set up.

IMO you will struggle with the L6, you should really be on a programable system.

get it running 2 bar and go measure the power

 

Why is he gonna struggle with the L6 ?

It will make no difference to the engine power WHAT SO EVER...

Mine is over 500...

Ported head
NMS cams
Siemens injectors
Full Race T4
NMS Inlet
2 bar Boost.
7.5:1 CR

 

I meant a off the shelf chip prob wont do, Didnt know you could live map L6? thought it had to be L8 atleast?

 

I didn't know you could buy off the shelf chips LOL...

Used to karl doing everything to suite the car

L6 is not the problem making 500bhp its usually the t4 LOL

 

dingy

Whats the nms inlet???????????

Did karl map your l6 for you?

 

dingy

so your saying the t4 is wank for 500bhp??????????

 

T4 is great for 500bhp.

Mine runs closer to 550 with AVA spec T4.

 

there are a lot of t4's around not many are good enough for 500bhp is what i am saying.

I have never had a l6, mine is l8.

 

so what injectors will i need then???????

any other mods needed to the electrics

ignition system??????

will a 2wd inlet with spacer plate be ok????????

 

2wd inlet has a crap elbow design...

I am not sure the volume of the plenum is the problem just how it enters.

 

dingy

I see what your saying about the t4. The reason i started the thread was to see if 500bhp would be easy acchievable with a few more mods to me car, i'm not aiming for 500+ as such if you know what i mean

 

just give it to noris and say 500 bhp sorted

 

dingy

Thats what i thought bu others on here are saying different

So what is a 2wd manifold capable of then

 

You never see a 2wd making over 450 normally so don't know on its bhp limits.

Normally people change the elbow on the 2wd by modding it or changing to small turbo escos.

 

euan that is exactly what alan told me on the phone the other day

 

ARP studs and a 205 block and 500BHP??


200 WRC long studded block is a very very good idea before you even think about anything else.....

 

RWD_cossie_wil

Why????????????????????

Any techical reasons behind that comment???????????????

 

205 with standard head bolts would be better.

 

As the power increases everything needs to be spot on with the map.

 

well at least you will have the t4 for 500 bhp m8 you must get a 200 block tho as i dont think the 205 one wont last long m8

 

I still don't get that at all...

If you can map the car on L8 or L6 then its going to be ok aint it ?

Seen 500bhp on both ecu's LOL....

 

cossiedave

The old 200 or 205 debate lol, some tuners say 205 will be ok some say 200 only lol

 

Listen to rapidcossie! My car is parked next to his to have the same treatment!!!

 

205 block WILL crack with thar power, build it once build it right

 

Im not saying that you cant dingy.

what I am saying that you need complete control over the ECU.
