So im ready to start putting a block together. the z6 block that i have has a spun bearing im not sure how bad the crank is but i will be tearing block down this week, my brother is a machinist so hopefully i can just have it polished and have him order me bearings. For pistons and rods i was looking into wiseco/eagle setup, my last vitara build was just too low compression and i want forged this time around, i did find a cp/manley setup for around $100 more than the wisecos. Im shooting for around 400whp so just curious if the cp/manley setup would be more reliable for bigger goals later on? any opinions or advice is always appreciated!

weisco/eagle's will work fine....Here comes the cheap *** in me....... Having forged is good intentions, but honestly, you can get TRUE stock bore teflon coated vitaras and custom length rods from p2po for $400 shipped.... They make it 8.5:1 c/r, and if your brother is a machinist, surely he can skim the deck of the block, and the head and raise c/r to 9:1 easily.....and this is good to go for 400+ whp, for 1/2 the cost of forged.... just my .02

Do you have a link for them? I deff wont knock the vitara setup just figured id go a diff route but id be good for 400 with those. I have a mid engine rwd ef and dont really dare going past 400whp with it.

Check out also the "SINGLE SLAMS" forum.. lots and lots of D-series setups done there that might interest you as well.

here you go man!

This is what I'm using in my current build, shooting for 400 whp.

can i have a link to that cp/manley piston/rod combo?

Boosted D thanks alot, your setup should be sick with the sc34 man. I was thinking hx35 setup just dont want something super laggy as i said its a rwd ef hatch and want to be able to have fun in 1st gear so i was thinking about using my old evob16 setup for quick spool, but still undecided yet. What im doing now is kinda just get it done to make sure everything holds up, its just about finished besides closing some gaps, gonna finish the wiring harness this week, extend the throttle cable and yank my old y8 mockup out. Id love to see pics of ur build

slob20 your welcome.....I hear ya on the 1st gear fun, my plan which should make 1st gear work ok, and hopefully keep traction as well, is instead of doing boost by gear, i'm going dual stage boost controller. stage 1 will be wastegate pressure at 10 psi, then flip the switch for 20+ psi......also going to use anti-lag with 2 step to help out 1st gear.

I am also thinking I might rev the stock head to about 7700 rpm which shouldn't cause any damage, but will help me stay in boost between shifts.....

slob20ef

That will deffiently be fun, as i said i have a couple dsmb16g turbos laying around and a rebuilt egay 50trim, still undecided on a turbo, tore the motor apart this morning and dropped my crank off at a reputable engine/machine shop, said he has put several honda engines together with ground cranks as the nitrade? coating is deeper than it will need to be ground, i am not a fan of this but i trust him as he put my buddys 500whp sleeved gsr together, and a couple other local 350+ whp b series. Im interested in doing those vitaras however id like to find a complete bottom end kit, with all gaskets, oil and water pump, rather than ordering a million things from a bunch of places but that might be my only option as fj still has not opened back up..

slob20ef

My brother mic'd the block today, and all is well so he is going to hone it for me and we'll still be in good shape to run 75mm pistons, so went ahead and order the vitaras with custom length rods, as well as some other goodies! Clutch masters stage 3 clutch kit, with lightened flywheel, as mine is completly shot! Dsm450s for now, wideband, engine gasket kit and some other odds n ends, got the wiring harness finished today as well, Crank should be done middle of next week and im getting my main hoop built tomorrow and should start doing the cage! thanks for the advice!

Nice man, in for pics, I wish i could say my build is progressing, but $ has me bent over at the moment . Definitely let me know how the ptw clearance turns out after the hone, what are you shooting for on ptw?

Mitch965

I got the same damn problem.

slob20ef

Honestly im not great with tolerances so as i said my brothers a machinist so i left that to him. He assured it would all be good and the hone would maybe take a tenth to 2 tenths of a thousandth off so no worries i trust him, i will be making a build thread for the car just havent had much progress lately. I will deff post up pics and make a thread tomorrow being that i should be finishing it within the next couple weeks.

You should let him know that the stock ptw clearance is very very small, and that those vitaras will expand a bit more than stock pistons, so the ptw should be in the .030 to .040 range, stock is like .010 to .018 I think, and thats a little too tight with vitaras, and anything past .040 you may get piston slap so try to stay below that number....

slob20ef

see we started honing the block out and found some pitting in the block, i still didnt have the pistons to mic them and see what ptw clearances we were working with, but honing the block to get rid of the rust he said we'd deff need to take off at least .001-.002 so i just got my 75mm pistons today, wish i woulda went 75.5mm im gonna see if i can pay for shipping to send back the 75mm and pay to get 75.5mm sent, then bore. ughhh what a pain in the ***! probably gonna hone this block more just to see what i could come up with, if it still dont work then have to bore anyway.. Ive heard of people going with up to a .007 ptw clearance but im not going to be the one who takes that chance.. Thanks!

slob20ef

block ended up needing way to much work, today i lucked out at the junkyard and found a y7 in a automatic 4dr. Tore the block down everythings actually in really good shape, so no need for the ground crank wooot wooot! Also mic'd the 75mm vitaras and the cyl walls and would end up with a .002 ptw clearance, doing a light to moderate hone hoping to get to around a .003ptw, also what are you guys running for bearing clearances? and Boosted D did you have to notch ur block with these rods? Thanks alot!

scottdh20

i wish i went with a forged piston over the vitara....hell its hard to pass them up at the price but just remember vitaras dont seem to like high revs....i only rev to 8500 at the track and 8k on the street/hwy and its really pushing it at the track and i could use those rpms with the holset

spoolie

Don't cheap out, run good internals and do it once. The Vitara way is junk, buy good pistons and actually raise the compression a little.

vitaras are far from "Junk", no offense. My last vitara setup held up just great and there are numerous people making well over 400whp with vitaras. I ended up getting the numbers and letters off the block to get oem honda colored bearings. This car is strcitly a pounder that just need to do its job, take the beating

LOL at this, you have no idea what your talking about, this rod/piston combo is good for 500+ whp......

And yeah the block does need notched with these rods, girdle/main cap bracket as well, just like with eagles etc.

slob20ef

figured that, last question i came up with 3green, 2 yellow bearings for the mains, 2brown and 2 green for rods, thats from the factory block/crank/rods. This setup should work with these rods correct? not too sure on different color bearings all throughout but makes sense rather than grinding or polishing an entire crank. Everything is still within oem spec so its looking like everythings gonna workout

this makes me laugh..

Slob20, yeah that will work fine for the bearings, might not hurt to measure with the new rods just to be sure, but it should turn out the same way, I just use king race bearings, they are like the middle size of Honda oem, and lots of people do this with no issues.

slob20ef

Well my oem bearings were suppose to come today, when i called the dealership the parts guy apologized for quoting me $160 for the mains and rods,and gave me the price of $240, told him nevermind. Im either going king race or acl race, also need to get a set of y7 headstuds now, gay
