supplies get really expensive quick.
if youve never played with one on a flowbench it's not wise/needed to port the intake, unless you know what youre doing on the exhaust

 

most of my stuff is home made...lol works very well i think..
im a machinest and a welder and engine builder for a living...

 

Somebody say porting?? lol

 

i am all for flow benches they are great tuning tools but most everyone gets so hung up on the numbers game that they cant do anything else and wonder why their car is still slow as ***** one thing i learned along time ago hot rodding throws more curves then a physics teacher can

 

I like curves...

Anyway, flow benches are like dynos. Can be very useful on one car (head) but nearly pointless to compare between 2 different ones.

 

ok after goin round and round about pistons Im finally ordering them tomorrow morning..
with total seal gappless rings


y hasn't any one slaped a m90 on the lsj yet. not the mp90...
ive seen alot of threads but no proof or success threads yet..

 

its been a month and a half but my pistons will be here this week

 

who is makin them

 

What for when there are way better options.
Now if you had one sitting there for free...
Zzp did it long time ago. Didn't even bother
Posting the results. It's less efficient than the m62.

cool that's wat i have in my 2.0 now...
Im goin with wiseco this time

 

i use weisco in my dirtbikes and motorcycles but my builder likes diamond for his ecotec builds

 

just a lil teaser.

 

well i have the block head and m90 at work today..

the head is getting moded for the 1/2 head studs and the m90 just got all cleaned up it looks brand new again

 

Machining the head for 1/2 studs

 

the head is ready for the studs...now just need to order the tap extender to do the block

 

Looks good man

 

What do you use to indicate a threaded hole? Only way I can think of is map out the head holes in a makeshift print and find a common edge between the head and block...

 

u dial in on the counter bore..

 

i hard a co-axle indicator it works in a 1/16 hole to a 12" hole

 

well its official after all the goin back abductions forth with wiseco i finally placed the order...payed in full...now its the long 4-6 week wait.
