Bennoz spends more money - NOS!

Am trying a little experiment tomorrow. Car is going down to the shop & the heads are coming off. Were hi flowing them, which includes decking (increasing the compression ratio) and porting out all ports as big as they'll go. The 2 parts of the intake manifold are also going to be ported out to match the head ports. We're also going to try & machine out the throttle body & fit a new bigger, brass butterfly in.

Will be a while before I have accurate power figures, as the car'll need to be re-tuned on the dyno when this is all done.

Will also post some piccies of all the machining work before we bolt her back together.

Optimistically I'd like to see another 20kws out of it, but realistically it probably be between 10 & 15kws.

so supercharger is out the window if your increasing compression? awww

Post by **Bennoz** » Mon Feb 04, 2008 2:03 pm

Nope. I have 2 engines

you rotten bastard!

how much is this little setup costing?!

Post by **aza013** » Mon Feb 04, 2008 2:10 pm

you now have my atention Ben

would like to know how this gos and the price.
would you need to do the injecters ( get biger ones) as well after all that is done or have you already done that ?

Post by **Bennoz** » Mon Feb 04, 2008 2:14 pm

I shouldnt think I'd need injectors. The standard fuel system only ever runs at 60% when flat out anyway. If for some strange reason I do, I'll be pinching a set of 275cc'ers outta a Magna.

This is all probably gonna cost me somewhere in the vicinity of $2000. And that will be mates rates...

im your mate... your his mate...

therefore jonowong gets mate rates too?!

thats a great price

what compretion are you running at the moment and what are you going to try and get it to

it would be great to see you hit the 140kws

Post by **Bennoz** » Mon Feb 04, 2008 3:05 pm

Well I'll be doing most of the disassembly / assembly, hence the good price

Currently running 10.75:1 compression (just a bit more than stock 10.5:1) I'll take it as high as I can without having to worry about clipping valves & filling up at Bankstwon Airport

Don't worry about the power, this thing is going to sound absolutely amazing.

People will think your packing something other than a 2 litre under that bonnet !!!

Yeah she'll be a bit rougher than the norm... espcially on idle!

I'll really have to keep the revs up on her, especially when we put in the alloy flywheel in a couple of weeks times

Post by **aza013** » Mon Feb 04, 2008 5:26 pm

so the GR has a higher compression than the gpx interesting I thourt they would be the same, well I lernt somthing today

you really have to get the lsd after that Ben.

Looks like its gonna be in the shop for a while longer than I'd hoped

Maybe a month!

good to hear ben!!...

The RPW chomoloy Fly's are great.... Mines a bit shuddery at very low rpm, but you can feel it wants to rev

jonowong · Post by **jonowong** » Tue Feb 05, 2008 2:05 pm

how shuddery? im considering the aluminum one!

Ben you ever thought about putting Mivec cams in the GR motor? what cams do you have at the moment...??

all i'm thinking about at the moment is when my crank is going to let go from all this motorsport if nothing lets go before it and if it does i might just save on the gpx motor and get a GR put the Mivec cams in and have my same redline. (only with less load/resistance apparently - i cant remember why - and less weight in the heads).

Mivec cams in a GR motor...i don't get it...
You'd be swapping over a fair few parts and the heads to support the mivec cams i think...which would mean same weight heads. The mivec cams with breathing mods WILL need to rev past 7500 as well as they're still making power (look at my dyno sheet if you want)...

Be much better doing what Bennoz is doing right now.

Thumbs up Bennoz, can't wait till i see the dyno sheet and your driving experience with this done.

Post by **Bennoz** » Tue Feb 05, 2008 9:35 pm

Yeah mivec cams would require mivec heads... which would require mivec the oil system, the mivec computer, the mivec alternator & the mivec wiring. Too much hassle for not enough.

This afternoon my mechanic suggested something very tempting... and not that expensive. A Nos kit!

Yeah, way too much to swap for too little gain...though mivec does sound sweet

Nos kit ? DOOOO EEETTT!!!! You know you want to!
