Not quite. They are file fit, including the oil ring rails.

Can you tell us how much mazworx is charging to do each job? Obviously mazworx is the best in the sr world and I would imagine they charge quite a bit because of it. I just want to know how realistic it is for me to send them my stuff to get worked on.

for how much and the experience they have doing this stuff. the price is well worth it.

you get a core refund and arp main studs. everything it decked to seal correctly, the block is completely cleaned, oil holes cleaned, the main bearings are oil groved. new oil pump. bored and resleeved, with a guarantee on the sleeving. http://www.mazworx.com/index.p...=2750

they have block al ready near completion then you tell them what you want. they do it to the block they have, then shipped it to you after a deposit is made then you ship your block and stuff back to them for a partial refund on your deposit.

Cant wait for another build thread by you. subscribed

Do you need a new crank shaft since you are doing a 2.2? Or are the sleeves bringing you back to standard bore? I'm a bit confused.

this is gonna be fun to watch

no

no actually. i am gaining the displacement in the over bore i am doing. stock increasing each cylinder by 4 mm

bring it to 2.2 ad a stoker kit depending on the kit could pump it up to a 2.4 . i saw one kit that kep the 86 mm bore and stoked it up to a 2.4 i think it be awesome to compine that kid with the over bore i am doing and try getting 2.6 liters that is almost a full liter more of displacemnt

Post by **White Comet** » Sun Mar 01, 2009 7:05 pm

my math is rusty, but 2.6 is slightly half more then 2.0, not a full liter more

Post by **idahotuner** » Sun Mar 01, 2009 7:21 pm

lol werd i know, i was slightly exagerating but the idea of making a 2.0 liter a 2.6 would be awesome

IDAHO! Dude I'm sad to hear you melted your rings. This thread should be great, and I'll be checking in more often now that I know it's here!

What you document on doing to your SR this time will be more extensive than most of the nico population haha! I don't even know exactly what a valve angle job is, care to elaborate or point me to where you did?

Dude your dad posting and a new engine build thread? What could be better!

Did you have to reshim the lifters last time I forget? You only have to do that once or twice right?

Gonna be a great process, nice shop I'm jealous.

i know tell me about it lol

3 angle valve job. the valve seat where the valve seals against the head usually has 3 angles fro mthe factory. the highest angle is for airflow then the two lowest are to help the valve seal correctly. the difference between these angles is usually 15 degrees.

usually 60 45 30 are the angles.

well mine are burnt so the valves arnt sealing correctly.

3 angle valve job implies regrinding all of the seats with new angles slightly different then grinding the angles on the valves slightly different to, off by maybe 1 or 2 degrees then the seat. to get more pressure on the seal point causing it to seal better.

we did a whole class and then a 3 hour lab on valve seats and such.

yes i reshimmed. shimming is not suck a huge deal with hydraulic lifters. the main thing is to make the sure rocker arm is sitting level on the cam lobe

You're going to need a new trans... That Sr trans isn't going to handle the amount of power your going to put through it, especially if you plan on dragging it or flogging on it alot..

Great build up Potato... Looking forward to seeing the results.

super sick... im almost done with my mazworx 2.2L all im waiting on is a haltech e8 witch im saving up for.. dam did my build get expensive. the motor was bank, but so was the exedy twin disk, the gt3567r, the proper fuel setup, and all the other expensive parts that i purchased lol. are you going q45 TB? im to broke right now lol ima use the stocker and upgrade that later.

yes my budy offered me his q45 throttle body, but iwill have to havea new flange welded on my intake manifold. and i dont want just anyone touching a now 600 dollar greddy intake with a saw and welder.

i might look into cahnging the angle of entry fro mthe cold pipe as well.

well said! That is what I was thinking!

Post by **Stripes** » Wed Mar 04, 2009 9:03 am

I am curious now as to exactly why 2.2L kits come with a new crank. What about having a 2.2 stroker would leave you with the need for a new crank shaft? Or do they just include it because it is better balanced or lighter or whatever? Say I was to buy the Tomei 2.2l kit. Would I HAVE to use the crank they include or would my oem one work just fine?

Post by **srdub-t** » Wed Mar 04, 2009 9:45 am

no stroker kit here. just 90mm pistons and some sleeves

Post by **idahotuner** » Wed Mar 04, 2009 12:07 pm

you can change the displacement of your motor two ways over bore it or stroke it.

over boring is making the diameter of the piston bigger

stroking is making the distance it is traveling longer.

both ad displacement.

combine them and you will have the benifits of both.

stock sr20 hasa 86mm bore X 86mm stroke. change the bore or the stroke and do the math.

Post by **Stripes** » Wed Mar 04, 2009 3:16 pm

Thanks, it all makes sense to me now. So if you were going to stroke a motor, not only would you need a different crank, but wouldn't you need shorter rods as well?This is getting me thinking.... 2.2l stroker kit + .2l over bore......hmmmmm
