decisions decisions

ok so i got 2,400 back for my taxes and im wanting to get my old 85 crx running again cant decide what route to take..
my options are this...
#1 rebuild my 89 zc with forged internals to run my turbo...
#2 rebuild the stock si that has a spun rod bearing...
#3 go with a junkyard 87 d16 teggy and not worry bout the wiring issue


i already got everything i need for the d16 swap such as hubs axles etc..for the exception of a 89 wiring harness that i slautered...

#1 will cost you more than $2,400
#2 will not give you the gains of an '86/'87 DOHC D16A1
#3 will probably be your best option

I'd swap the ZC right now and start working on the wiring (you're going to have to do it eventually), then pick up a junk yard D16A1 block and rebuild it as your budget allows. When the rebuilt block is done, you can then swap the ZC head onto your new block and you'll be ready to go turbo!

my zc block needs work though i had turboed it on stock internals and it lasted only 2 weeks b4 it started having major excessive blowby ... at that time i never checked into the cause of it but my guess is rings. is the d16 block better than the zc???

The '88-'89 D16A1 block is exactly the same as your ZC (assuming you have an '88-'89 Integra ZC), so it doesn't matter which one you rebuild. The only difference is the cams.

What car were you running your '89 ZC in?

ya its an 89 zc took me forever to find the engine code on it..... its stamped on the intake side of the block. and i got the long block so ya its got zc cams as well. the tranny is a usdm 87 integra though and the ecu was an 89... after i ruined the engine i took it out so i could rebuild it and put it in my other crx thats alot nicer and now that it has a spun rod bearing im gonna try and get it done. (key word try) lol..

i tried to put some pics on here but couldnt figure it out but here u can see a few http://www.myspace.com/cody85crxzc

Nope.

I see "ZC" but nothing to click on.

sorry its such a crappy pic.

Do you have a pic of the head?

I'm just wondering if you have the correct ZC since there was an '89 Integra ZC and an '89 Civic ZC. The Civic ZC won't easily fit into a 1G CRX and the obvious difference is the bolt configuration on the valve cover. This is why I asked which car you had been running the ZC in.

i had the zc in my 86 crx the body was hella crappy so now since my 85 is broke down ima swap the better powerplant into the good body...

Yep, that's the correct valve cover.

I'd go with options #1 and #3. Pick up a D16A1 as a temporary swap while you're rebuilding the ZC. You should be able to find a D16A1 in your local Pick and Pull for under $200.

cool yeah so im gonna run with an 86 87 d16 then along down the road built up my zc... any ideas on how much thats gonna cost??? i saw some je pistons for 375 and eagle rods for 450 plus ill need to get the block cleaned, miked, and maybe bored or whatnot plus ill go with new oil and water pumps that only obvious..

I have somewhere around $1,500 just in parts and machine work on my D16A1 long block, and that's without forged pistons or H beam rods. I also ported and polished the head myself (with guidance from my machine shop) in order to save some cash. You'll probably have at least $2,500 into your turbo long block.

yikes and thats not including management for the turbo .... im starting to get 2nd thoughts about this whole idea!!

How about getting a junk yard D16A1 and boosting it until it blows up, then buy another junk yard D16A1 to replace it. The only difference between a ZC1 and a D16A1 is the cams, so you can swap those into whichever motor you use. Although a friend of mine gets better results with stock cams in his turbo D16A1.

ya not a bad idea on my zc engine my turbo worked very well at like 6 pounds till i started getting cocky with the boost lol... alota people said that i couldnt get it up past like 3 pounds with the map sensor or whatever but i never had any trouble maybe i just got lucky i guess... but im kinda wondering if itll run ok with a d16 that has the vacume advance and all that older stuff.. i really dont feel like messin with wires at this point in time plus im in a hurry to get the car running and out of my friends yard before he tows it off... oh ya and do u have any idea why people use those aquarium check valves for???

how many pounds does ur friend run on his d16a.. and is it stock???


sorry for the multiple questions... i apreciate all the info

Here's a link to my friends boosted D16A1 dyno results.
