just having my wisdom teeth out iv got a few days to spend on organising my engine rebuild currently ive got
-bored 20thou and honed ea block
-ceramic and teflon coated pistons,20thou
-rebuild kit
-tickford computer and chiptorque chip
-wade 1636 cam
-and all ef external parts to bolt on
-4.11 diff gears

i am going to send the head down to hoppers heads in melbourne they say it will be able to flow 175rwkw with bigger exhaust valves,ported,cam and springs, but im wondering what else i can do to flow more and possibly make more. any suggestions? also its going to be on nitrous.

Have you already got extractors, a performance exhaust & cat, a good air filter and some form of cold air induction?

If you're talking 190 rwkw, you'll need a more radical cam which will make the car unsuitable for street use. Straight off, a lot of blokes here will say you'll need forced induction (which may not be an option if you're on P plates).

The money you will spend to get the power you want you may aswell don't spend a sent trade up to a BA XT falcon, with 183kw at the motor with around 139rwkws. 40kws is easy to get.

Except the B series is heavy...

190rwkw out the and E series is going to be hard yards without going forced.

I had my EF head modified, by Hoppers Express Cylinder Heads, and still have to go back with a dyno readout for them after the engine is run in. The owner, Trevor, is a good bloke speak to and happy to answer any questions. They also rebuilt my bottom end.

You'd need a seriously good aftermarket ECU setup to run and allow for a more radical cam - especially so if trying for high power output and retaining streetability.
Chiptorque wouldn't seem to be anywhere good enough for really finetuning and adjusting around a big cam.

i realise this, what cam would be suited for higher kw and torque and what ecu are best suited for falcon 6's

In short 180-190RWKW N/A out of the E-Series in next to impossible. Many have tried, spent A LOT of money, come close and moved on to forced or 8's.

It is possible, but needs big money and also big revs. I know a guy with a brock EA pushing 175rwkw on the standard log manifold, off the shelf cam and a megasquirt ECU...

I have heard of 2 cars that claim they make 197 or 200rwkw

here is one response i got off eBay for a Guy Selling a Head - this was the heading on his sale:-

4L Head and Cam Package EF-AU bring 200kw at the wheels

I asked him does he has proof

Quote:
Yes as a matter of fact I do have proof. I have one printout and receipt after I got my chip flashed. I got it done through holden and used their equipment as my brother works there. Mind you I also had the throttle body and intake machined to match, but that cost me hardly anything. Keep in mind just to use these parts with a stock ecu, you need to have extractors minimum. We are dealing with high quality parts here.


This was his add
Quote:
Here are the Specs for The Camshaft

FORD 6 Cyl. EF Mild Performance Cam
Part Number Lobe Separation 113 Valve Lift
Inlet Opens 20 B.T.D.C. Inlet Closes 62 A.B.D.C. 0.494
Exhaust Opens 64 B.B.D.C. Exhaust Closes 14 A.T.D.C. 0.472
Inlet Duration 262 at 0.050 262 Advertised
Exhaust Duration 258 at 0.050 258 Advertised
I also have an ajustable timing sprocket and roller rockers included.
Head
4.0lt EFI EF Tickford Head
Inlet ports machined to 30 thou
Stiffer valve springs to suit cam and rocker gear
Machined and polished for a high compression head gaskets been machined and worked to match the cam and EF-EL engine specs.
All together makes just over 200KW at the wheels on a a stock EA-AU III. Don't know how much at the engine.
All products were purchased from Headtec in melbourne for $2500


Also a Guy in NT that was selling some JMM stuff claimed he got 197rwkw

Quote:
Hello and thanks for looking,
Today i have the crow cam out of my EF Falcon 6 cylinder. Part number is 2222546. All the cam specs are on the sheet in the pic. You will need a programmable ecu to run this cam as a standard ecu wont run the engine with this cam fitted. And you will also need an adjustable cam gear to adjust the lift at TDC (i will be listing mine shortly). I was using standard hydraulic rockers.
This cam makes the engine sound really lumpy.
With a wolf 3d ecu, extractors, Jim Mock stage 5 head, modified inlet with 75mm throttle body and the crow cam i got 197RWKW on standard injectors. I purchased the cam in December 2004 and it is still in the engine which is sitting in my shed. If you would like pics of the cam, send me your non ebay email address and i will lift the rocker cover and take pics.


Either alot of eseries guys are full of s**t - which i kmow alot are

Or you can get these numbers but have to spend the cash to get there

i think 190rwkw na is probably do able but the bottom end will need a lot of work, higher compression and a huge amount of porting,a fairly wild cam.

but i think the ecu will be the let down..
i went supercharged on a stock engine with the std ecu and got 160rwkw.
i then went to a piggyback and got 175rwkw and in the end went with an ems ecu and got a 194rwkw.
so overall the aftermarket ecu gave me a 35rwkw gain..

Based on what i've done and seen done to the old crossflow motors, it really must just be in the factory ecu, if you went aftermarket i wouldn't see why you couldn't get a standard xr6 head to go 200rwkw's.. think 250-260@50 cam, 550thou of lift.. which is getting on the large size.. think the stock cam on these is 204-5ish@50.. (could be wrong thou) My next project after turbo on the el, is a crossflow motor i build for an xe i had, it is now going into a te/tf corty, with a 230@50 hydrolic cam 10.5-1 comp 600 vac sec holley it made 155rwkw's with a stock curve on the dizzy.. this build be uping the cam to a 260@50 solid with a 650dp holley aswell. aim is 220rwkw's but should make 200rwkw's easy enough! come on cam like booost haha..
