Teeth? LUXURY! When I was a child we ate by putting rocks in our mouth and jumping up and down.
Awsome!!!! would love a mk1 some day!!
just keep them ideas in your head fella ha ha
has scrapped the sig with all the cars to do list!!!!! 3 novas i own says it all really
Hey,
I've been waiting patiently for ages for an update with some decent current pics and vids on your car. Sort it out!With all the work and ingenuity you've put into the mk1 it deserves better than being sat in a garage.
Paul.
Never stick your finger where you wouldn't stick your dick and you won't go far wrong.
noooooo! you cant sell it after all the hard work you have put in, youll regret it afterwards honest, i regretted selling my newly built xe straight after building it, i wish i still had it now.
a quatre mile video would be great
steve
the colour is awsome
wow!!
i've read the whole thread today !
great hand made works
great solutions
absolute not worked at office... i'll be fired tomorrow
do you have some pictures about the rear drive?
Looks like a good inlet

small update.
been working on my own company for a time and haven´t got that much time for the Astra.
But i have bought a new oilpump, Z20LET
As i´m going to upgrade with oilsquirters
and need some more capacity to pump against the high centripetal forces when revving 7500rm with 95mm stroke.
A question thou,,
is there anybody that has calculated the flows from the pumps std vs Z20let?
i thought it was the pressure thats the issue not flow.
www.wix.com/vxlgsi/zxr-750-r
It´s flow who is the most important part.
If your pump doesn´t flow enough, your bearings will run 'dry' at higher rpm as it can´t keep up the pressure needed to overcome the centripetalforce etc etc.
You don´t want to adjust your pump to get higher pressures as it will run 'dry' anyway at higher rpm.
and with high pressure you heat up the oil unnecessary and wears it out.
Keep in mind!
the pressure you see on your meter in cockpit doesnt tell you anything but the pressure going out from the pump.
The pressure that reaches your bearing are way lower.

Dry sump it Patrick, i think thats the safer option especially with a grippy 4wd...no oil surge issues with hard cornering, drifting, donuts
The zlet pump does flow more but i'm not sure by how much. It also has a steel drive gear which doesn't disintergrate at high rpm which is nice.
Definatly with you on monitoring capillery pressure rather than whats coming direct out the pump![]()

Yes i know dryspump would solve a lot of issues.
but! i haven´t got any room for it
If this setup doesen´t work, then i´ll have to remake whole exhaust, manifold etc etc..
I´ll try this first.
I had some abnormal wear on bigend bearings, that´s why i´m upgrading also.
But i think the wear i had on the bearings came from a little bit to early ignition.
But, i got the pump for 'free', i ported and polished a Coscast head for a friend.
That LET is about to take XE camshaft to a whole new level

Ok sounds good.
I think what might be a good idea here is to look into getting the correct oil jets. Drop ChrisReay a pm and he will let you know what we use, atleast thats one option.
We dont use the 17dtl jets like most people on here.
Yours being a fairly unusual build doesn't help, theres nobody to compare with really, i hope premature bearing wear isn't part of the running nature of somehting with your stroke, bore, torque and rpm. The stories ive read about people running 2.2, 2.3's in the past have never been great
Just curious, what kind of oil pressure were you seeing? I'm sure those violent launches didnt help as the oil would be splatered against the back of the sump for a good whilelmao
"THE ROB"
big wing and good baffleing are the way track/drag evo's are going with high cornering speeds/launches
i think you will have to bench test the pumps to determine flow at your chosen pressure i can't see anyone having flow data for them

would a z20let oil pump be a good upgrade for a c20let?
what are the benefits and is it a direct replacement with no other modifications needed
300bhp mk3 astra GSI LET (a work in progress)
I got baffeled tray and 'windage' catching.
An oilpump with more capacity is always a good invest when tuning an engine.
My old pump had steelgears and plastic valve.,, but that doesnt add more flow.
The squirters i tend to use comes from BMW M5,, dunno the engine code, but it´s the 3.8 litre straight six.
I will also make more mods to main bearings, more holes in them basicly explained.and a groove in the mains behind them.
just to feed the squirter and to more easy feed the bigend bearings with oil.
Hi, do you have some pics of the rear running gear on the car I am in the process of the 4wd conversion and any info will be usefull but am running the gm gear.
IIRC he uses the same rear axle as calibra/cavalier with toyota rear diff. Good idea with the bearings , and we went for the bmw oilsquirters for my mates turbo build too![]()
C20XE , machined down pistons , MS-I v3.0 , HX35W 1.2bar and broken F20
A little pic from where i´m at, at this moment.
i´m upgrading the things i mentioned above.
has gone through the hardware in the engine, looking good

Looks likes its never been ran almost
Was there never any concrete on the inlet side of no. 1 Patrick? If not.....reasons for this please matey.
Bit gutted this has to be in bits so early in its life, suppose that R&D for you.
Keep up the good work dude![]()

about the concrete,
i saw that it had wen´t loose, sad,, but i think there will be no problem to add new concrete as i got the 'studs' that keeps the cylinders in place.
i have measured the cylinder and it´s round and fine.
But i´ll think i´ll use epoxi instead this time as the concrete may disform the cylinder when hardening.

Hi which block did you use for the build? I am using a x22xe block and the water jacket ports look slighty different. Also do you work for sanvik coromant?
Keep up the good work!
