Can I suggest it needs tighter lobe seperation due to the poor induction on a xflow. The head flows like poo and there is more hp in the cyl head than you think when ported by a good shop not for a dirt slinger. By using 104-106 lobe will aid torque then the webbers and ported head extend rpm range and hp made if used with 11.5 comp plus. Generally I use no less than 8 degrees seperation between exhaust to inlet duration also. 
 
I use Johnny Marshall of Marshall custom cams and Phill Duggan of Surecam. 

Well... my engine could be copied for nearly half of a $18,000 clevo. However every engine needs fuel system, ignition, exhaust and so on. 
 
A turbo xflow is cheaper than a na clevo. Remember a clevo still needs cyl heads to work, ignition exhaust manifold carburettor and so on. But its all the same regardless of engine really.
 
A xflow bottom end needs a quality damper and flexplate. Pushrods, convert to a solid lifter cam and cyl head porting. Porting is free hp that all but doubles with boost.
 
But big 1 is how much can you do yourself if your asking money money money before you start. Money usually kills a build before it starts in most cases. I however just did it over many years...and still going. 
 
First race out from turbo build raced a NA clevo XA. Beat it running a 10.7 to his 11.1.
Next meeting first race was against a clevo xy. We both went 10.3 129 but I won by a better reaction time. But my car costs way less than both of theres and beat em. However its still more than most want to spend which is the part that makes or breaks the car.

I just put 110nm or 80ft lbs on the front stud. 
 
80nm been stock setting.

Common thing is people think barra swap is easy and dead cheap. Till they keep finding stuff thats needed and how much they can not do. Equals expensive. 
 
Xflow needs ALOT to make power and be reliable but its rarely what people do and or use and then when results are not what they wanted there blame the engine, not the combination. 
 
Then people think go barra cos there poor decisions.TBH the barra platform is waaaaaaay better but it has so many more years development on it so it should be too. But people expect Barra type performanceon xflow money. Its not a thing.

6-2-1... So 2 pairs of 3 into 1 merge into a pair of 2.5" collectors into a single 3.5" merge collector then back into twin 2.5" pipes. Single 2.5" is not big enough tbh. 
 
 
 
 
 

TFI dizzy with a module you wire 1-3-6 pins 2ND grey box from the top.
 
6= white from MSD
3= red from MSD
1= earth to ground
 
Orange from MSD to coil +
Black from MSD to coil -

You can tweak mix the wires around and still it to work,you can convert it to no module,you can run it from a EST dizzy aswell which is no module.Ando has alot of luck with the EST dizzys...
 
Easy as.

depends what year the pedal is from? if it's from a ute/van from 1988 it takes an E series cable.(or can but they are longer) 
otherwise XE is same as XF upto 1987 at least... V8 ones are longer
 
that's from memory of well over 10yrs ago.. should see if the mounting suits at the firewall..  they have a 45 degree angle on the mounting flange on the XE XF early.. the later one it mounts the cable outer to the pedal bracket
 

Modern NA 4 cyl cars have twin 2" - 2.25" exhausts. You have to get it out of there.   

i was hoping you'd find this thread, because i was going to post similar.. extractors haven't made any sound difference i've noticed before

Like a Clevo!

They sound no different. Only way to make a exhaust sound good is to put a stout engine on it.

84DA block is one piece rear main, (92mm x108mm x9.5mm), 86DA 95mm x110mm x 10mm, Yeah nearly like someone put a 84DA crank in a 86DA block
one way of comparing cranks is flywheel/flexplate bolts, 84DA crank will be 7/16" UNF, 86DA being M10x1.25.
 
Found a Volvo rear main 92mm x110mm x10mm

Its got a 84 DA seal in it but needs a 86DA unit. Same size as a EF seal.

So first thing to know is the rings rotate in the bores as they go up and and down so don't stress too much. But for the argument I set the oil rings 180 apart from each other and find a spot on the piston im happy with. Then the 2nd ring goe's as far away as you can get it from the "top oil ring" gap. Then the top ring is 180 opposite the 2nd ring gap. 
 
But the rings still rotate in the bores at there own rate anyway so don't be too concerned.

Pushrods and lifters (if flat tappet) do too. Along with valve springs if you watch a spintron in action.
