Crazy ZC
 

Hey all whats up.

I just wondered how built a zc would have to be to reach 300+ hp with a custom turbo and nitrous. (kinda like the one on zex.com) Im gonna control the whole thing with a zdyne and zex nitrous kit.

Would it need to be sleeved or not, is the one on this site sleeved? I have heard getting a block sleeved it not too cheap but makes it a lot stronger.

I'm definitly gonna get rods/pistons.

stock zc's can only support about 200 or so at the wheels, ive heard 220, but i dont know if thats whp or at the crank. i plan on building my zc later, but i wanna do a 6psi turbo first. college is expensive, so nothin much now. you would definitly need some pistons and rods, crower makes good d series, and i think endyne makes rollerwave pistons for d series(jeff, is that what you got in your built one?) if not, srp makes some, they should be ok with good managment. man, i wanna build my motor.

oh yeah, crower and hks regrind cams for zc's. gude made cams in the past, but they are HARD to find, ive only heard of them once. i found a small company, i think its in washington, colt cams, he regrinds too, i talked to him personally, i think im gonna have him do mine this summer.

If I remeber that Zex car has stock sleeves, but they filled the coolant chamber with Devcon aluminum epoxy, basically for reinforcement. I dont think the car will even run on the street like that, you would have some serious cooling problems.

Sleeving is a good way to go, it cost about 750 bucks, but the block is damn near bulletproof afterwards. I didnt have that kind of money on my setup, but I went with www.theoldone.com Larry Widmers setup called "Posting" it basically uses aluminum alloy studs that are the same as the honda block, and they are drilled and tapped on the outter shell of the block and screwed in until they just touch the sleeve. How much power can this support? I have no idea, but larry runs over 20psi on his d16z6 with the same type of setup.

Cost was like 300 bucks including shipping.

that "posting" looks gay dude... if its screwed till it just touches the liners then it is going to offer slightly less than ---- all support, you may aswell jam a few bits of wood down there for all to good it will do


you could fill the gap with some epoxy type substance then cnc out some coolant holes right down the block length


the best (only imho) option is the golden eagle iron liners


i will soon be turbocharging a peugeot 1.9 XU engine for a friend, which has wet liners he doesnt have the money to be able to have some iron liners like the golden eagle ones machined up (even at mates rates!)
so i was thinking of something similar to a block guard but with decent sized gaps for coolant to pass through... so if you looked down on it from the top it would look like a castleated nut.. there would be two of these.. one presses about 1/2 way down the liner and the other 2" below deck height... obviously easier said than done if you dont have the tooling or skills to make them

Honda sleeves and blocks are pretty well built, the extra support that the Posts/Studs gives is enough for some serious side load on the sleeves. I look back and would rather have got it sleeved, actually I would have rather just filled the entire sleeve with devcon aluminum epoxy, but I was short on funds and the car was going to be street driving.. Now things have changed..

Posting/Pining is better than a simple block guard, but not as good as sleeving, so its a pretty decent comprimise. Pounding a shitty peice of aluminum in the deck of a block (blockguard) will easily distort the sleeves. ::)

Supposivly Endyn has maximized the thust axis points of the block and installed the studs accordinly. If its so "GAY" why does Nascar use this? :o

Ya it seems like sleeves are the way to go. I was gonna turbo it now and the build it after i grenade it but... i got a blown zc that im gonna rebuild low compression.

This will be a street car so epoxy is not an option.

My goal is to beat a c5 vette for under 6 grand (better than a 13.5). And I think a crx is the way to go. SO far I have spent 2 grand on a crx, si trans, zc, clutch, flywheel, n20 and all parts to fix the car. 4 g left for turbo and building the engine... maybe ill go a bit over budget. Still smokin a $40,000 5.7L(?)with a $10,000 1.6L is gonna be koo.

I'm definitly leaning towards sleeves for the new block.
$750 is a bitch but I wont regret it later.

Re:Crazy ZC
 

that block looks o ringed.. is it?

never seen a pic of one but heard about them.

Re:Crazy ZC
 

Yup, block was O-ringed using a copper head gasket.
