Yeah the standard air box is in a hideous place on them tbh. You'll see benefits from taking an air feed direct from the scuttle panel if it's possible mate

As in itbs or oe inlet? Or airbox?

If you run high comp with 403's you should definitely see somewhere near 230hp. They're a similar profile to the R3 maxi cams I've got for mine. Torque wise your looking at around 170-180lbft which is also similar to the R3 maxi setup. That's based on running the oe inlet and not itbs though...

Surely The answer to that's obvious from my post earlier on this morning?

Good question there mate! The combustion chamber is a different design, but you could replicate it on the 1*2 head. It's a relatively simple machining job, but obviously they all need to have the same volume. To get the ports the same - your fucked. That's the simple truth. The exhaust ports...

Flol! Ah! Maybe that one then! Ha ha! I remember racing one on the way home from the billing show and one of the turbos let go!! Don't think the owner was too chuffed about being out dragged by a standard looking mk3 astra gsi! Doubt the turbo expiring helped either. Whoops!

Yeah just a tad!! Lol! VBOA is vauxhall Bedford owners association mate - they basically have a big show at billing aquadrome. I used to go all the time when I was a vauxhall man. Was a cracking show tbf, more like a social event than a car show.

I take it you'll know/know of David Franczak (sp?) then? His is mint. Seen your dads at the VBOA on several occasions.

It's wilwoods mate not brembos.

Flol!

Lol! Glad your pleased with it mate! I'm also glad to see its not just me with size 7 feet!!! Do you have to buy shoes from Clarks kids range as well?! Flol

Lol! No worries mate.

If you can let me know what your trying to find I can let you know what wires go to where mate in terms of sensors.

If your going that wild you want to go forged hi comp pistons then imo. Stronger than the oe cast items. Also it's worth keeping in mind that the off the shelf itb options are too small and WILL restrict the power output.

^^^^^thats crying out for a scuttle induction kit as well dan! I've got a special airbox for mine.

Do you want itb's on it? To run the constant vvt you need to run the wiring for the cam phase sensor that's in the 197 head. You also need an ecu that can run it, but tbh you may be as well just running it the same as a 1*2 - on/off. I'm only going to run it because I've got some particularly...

Yep! I'm following this as well!

Exactly!

Lol! What have you learnt today?

Bearings are larger diameter on the cup packed 182's. Driveshafts will be slightly longer as well, but that's because of the wider subframe wishbone mounts. They share the same track width as the 172 cup you see.

I *think* you can just do the swap tbh. Just means altering your tracking as the cup packed 182 hubs have a different steering arm. Its slightly longer than the 54mm bolt spacing non cup packed hubs.

It most certainly is mate. The hubs were sent to me already shot blasted and cleaned up - made such an improvement! They impressed me that much, I sent a picture to James and got him to upload it on here when they'd been done!! The machined parts are zinc plated mate, but not the hub.

Don't waste your time mate would be my advice. There's more weight in a Mars bar than you'd save from cutting metal out or drilling holes. I'd look at changing stuff like the bootlid, bonnet and doors for fibreglass items if your really wanting to save weight. Costly though.

That's because the rod end didn't measure it with the vvt engaged mate.

I've not seen a 200 head mate so I can't comment. Same casting but different inlet runner cast into the head plus a better designed combustion chamber to reduce shrouding of the valves plus it's fully hemispherical. I'd say the inlet valve would go plus 1mm, maybe a bit more. Maxi evo does...

So is it still running a dephaser or not? If it's on a dephaser you won't feel any issues when turning it over by hand mate.

I agree that the 1*2 hasn't got a good cylinder head design, but the 197 head is far superior. In R3 maxi evo spec they produce 250hp - and that's on the oe inlet manifold. You just need extremely deep pockets to get big hp n/a

Vvt or non vvt 422's? If it's vvt 422's then you need to keep in mind that the dephaser pulley advances the timing by around 16 degrees at around 1200rpm. You can measure as much as you like, but if you don't take that into consideration your fucked all roads round tbh. I'm amazed that you...

@Ant_Smiggy looks like I need to be going faster as well then as I still run with my fog lights in the front bumper! What you think @Martin.? :wink:

If you had no oil pressure issues beforehand I'd stick with the oil pump you've got. Clean it out, check the pressure relief valve plunger moves freely, pack the pump full of grease and run it again. The grease will generate the suction you need to get oil pressure in a fresh engine just in case...
