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

Alps Pacino

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

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

cossiemanden

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

Alps Pacino

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.

cossiemanden

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

Alps Pacino

cossiemanden

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

cossiemanden

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

rapidcossie

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

Dingy

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

rapidcossie

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

Dingy

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

Alps Pacino

dingy

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

Did karl map your l6 for you?

Alps Pacino

dingy

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

rapidcossie

T4 is great for 500bhp.

Mine runs closer to 550 with AVA spec T4.

Dingy

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.

Alps Pacino

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????????

Dingy

2wd inlet has a crap elbow design...

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

Alps Pacino

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

jacko

just give it to noris and say 500 bhp sorted

Alps Pacino

dingy

Thats what i thought bu others on here are saying different

So what is a 2wd manifold capable of then

Dingy

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.....

Alps Pacino

RWD_cossie_wil

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

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

Dingy

205 with standard head bolts would be better.

rapidcossie

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

cossiedave

iTrader: (1)

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

Dingy

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....

Alps Pacino

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

rapidcossie

Im not saying that you cant dingy.

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