cmgogo Posted June 1, 2010 Share Posted June 1, 2010 So got my motor yesterday, its a z6, good condition. As soon as I pull the truck out, the motor goes on the stand, and the trans goes on the bench. Plans vitara custom rods setup up head done with crower stage2 mild turbo cam, with bisi hardware go autoworks mini ac ram mani skunk2 intake mani custom downpiping, dump tube plumbed into exhaust (emissions in OR are anal... kinda) have a shop set up for tuning (even though it wont be for a year or so) debating on turbo size, want something small, fast spooling, thinking a 20 or 25 trans is a z6 trans, getting gutted and rebuilt, swapping 5th, looking into if its possible to swap 5th from a b7 trans. also debating on mfactory or qualife LSD, although, im leaning heavily towards the mfactory. the trans casing, block, head casting, and v/c are going to get hot tanked (aluminum only tank) then get coated, probably a bronze, or anthracite/bronze combo As the build goes on ill post pics (as well as when i get parts) any suggestions, info, feedback are greatfully appreciated. overall power goals are 200-220, but torquey power, not all high end (hence the tiny turbo) (maybe not lower the compression with the vitara/rods but keep it around stock?)

HONDA CRX 88 SI Posted June 1, 2010 Share Posted June 1, 2010 Sounds all good an if you plan on swaping fith gear from a b7 trans you be doing nothing if i am right they have the same ratio and to get to your goal of 200-220 stay with the 20 the 25 is to damn small lol. As for the vitara set up i have nothing but respect, it has showed me up in the past. lol Link to comment Share on other sites More sharing options...
SpeedDemon Posted June 2, 2010 Share Posted June 2, 2010 build sounds solid and will show a good bit of reliability. +1 on the mfactory lsd, good manufacturer good luck with it all. post pics asap lol Link to comment Share on other sites More sharing options...
..SSR.. Posted June 2, 2010 Share Posted June 2, 2010 5th gear is the same unless your Z6 is an Si. Si has .750 5th, all others (92-00) have .702. Don't coat the case. If you drive the car hard, the trans will see temps around 310*F without a cooler and with the bare case. That is already 100* higher than the fluid should see. Coat the case and it will get even hotter. MFactory LSD has better runout than the Quaife, it's stronger (forged versus the Quaife billet), has tighter clearances, and is cheaper.

cmgogo Posted June 2, 2010 Author Share Posted June 2, 2010 ssr! just the man I want to chime in! I was actually thinking of plumbing a cooler (electric pump obviously) to the trans also this will still be a DD, so I want a little longer of a gear for 5th (3.5K on the freeway SUCKS!) so what would my options be?

..SSR.. Posted June 2, 2010 Share Posted June 2, 2010 There are no options for 5th. Link to comment Share on other sites More sharing options...

You can always anodize casing. I dont know that it will effect dissipation of heat? Link to comment Share on other sites More sharing options...
cmgogo Posted June 2, 2010 Author Share Posted June 2, 2010 they do make a pigmented alumiblast in bronze, so thats probably what id end up using anyways if I were to coat the trans, but if ssr says dont... then you dont (cause ssr is the tranny guy). and as far as custom gearing, I dont have the equipment to mill that, nor the $ to pay a shop to, look like ill be sticking with the z6 trans, just cleaning it and rebuilding it.

..SSR.. Posted June 3, 2010 Share Posted June 3, 2010 Custom final drive = 10 x $534.95 and you have 9 spares. Cast can't be anodized. It takes more than a CNC machine to make gears. They need to be treated, finished, etc. No need for custom gears. I sell everything you need. Link to comment Share on other sites More sharing options...
mpearce1974 Posted June 3, 2010 Share Posted June 3, 2010 I am considering the same thing, I want the 1-3rd fun, and 4-5th mileage in my DD. Link to comment Share on other sites More sharing options...
..SSR.. Posted June 3, 2010 Share Posted June 3, 2010 You mean the 1-5 fun and mileage in your DD? MFactory 1.000 5th = 47mpg in my car. Link to comment Share on other sites More sharing options...
mpearce1974 Posted June 3, 2010 Share Posted June 3, 2010 You mean the 1-5 fun and mileage in your DD? MFactory 1.000 5th = 47mpg in my car. I do a lot of around town driving, and all my fun is 1-3rd when I get a little throttle happy! Some areas around house are 30 MPH zones so I cant use 5th but do use 4th. I would love to have one of your trannies, and do fully intend to get one if it can be set up that way. What kinda price would I be looking at for a D-series set up the way I want it?

..SSR.. Posted June 3, 2010 Share Posted June 3, 2010 With the 1.000 5th you can cruise at 20mph lol. If your mainly concerned about 1-3 then I'd go with a FD. The 4.7 or 4.9 would work well with 220whp. $1,499.85 plus shipping, add $150 for a Z6 core or $275 for a Y8 if you don't send your trans in. That's the MFactory helical LSD and diff bearings, MFactory FD, OEM parts, and labor (includes media blasting the case). Link to comment Share on other sites More sharing options...

I am considering boost and going for 200HP on solid rebuild and nice tranny. How measurable would the wow factor be on a stock Z6 until I boost? I have stock SI tranny now. Trying to decide if I want to do this sooner rather than later. If its a nice difference, I may do tranny now, find Z6 and tear down and build over the next 6 months, I have paint I am wanting to do as well.

..SSR.. Posted June 3, 2010 Share Posted June 3, 2010 Trans is a huge difference. It will probably be similar to boosting it on low boost as far as the butt dyno goes. Link to comment Share on other sites More sharing options...
Xeryon Posted June 3, 2010 Share Posted June 3, 2010 honestly, to me the butt dyno really is the most important part. $1500 wasted if the car doesn't at least feel faster. Link to comment Share on other sites More sharing options...

It'll be faster..with boost you have zero traction in the lower gears...
