wow thast some informative stuff there from the dyno

SINISTR

its a DOHC... not a SOHC.

Im looking to get some cams as well - i just need to get the best profile without changing ECU for starters - maybe down the track... and might get a worked Throttlebody just to let it breathe better. It looks like its running pretty rich at the higher RPM so with a bit of mods I can try get it to even out..

i c yeah but i hav the jdm sohc zc, but now i know about the other motors on the dyno

SINISTR

is anyone going to post their 1/4 mile times for their ZCs?

SINISTR, that dyno is like 25% drivetrain loss. tell them to recalibrate and or you want your money back. lmao.

are they just blowing **** out there *** or what</TD></TR></TABLE>

Rover increased the compression ratios on the cat equipped cars to make up for the power that was lost by using the cat - this happened at the same time that the UK law changed, and cats were made compulsory.

Wrong.

We got the D16A9, and the B16A1 - Thats it.

There is an awful lot of incorrect information in this thread.

I just had my CRX Dynod on the weekend.

Its running a D16A8 Auspec motor, with Intake, RSR headers and Exhaust - and made 102HP@wheels (76kw)

There are plans for some Cams as well - but unsure on a profile yet, as I want to use the stock ECU and valvesprings - nothing too 'hardcore'.. I'll potentially be happy with about 115-120@wheels.

I can say that the RSRs made a bit of a diff as other JDM ZCs there made between 90-100HP with similar mods

What can you guys recommend for other not so expensive mods but fairly 'good' gains?

cheers

Mike </TD></TR></TABLE>

LOL!! If you say so

SINISTR

yeah - as i said this is one of the dynos here, there is another one here and a comparison my friends RX7 Twin Turbo made 237 on the dyno I did, and then he went on the other one and only made 207 - so thats a further loss...

anyway - its only a tuning device isn't it? there is no way of getting the 'true' figure anyway you try.

daum thats kinda living on the edge im suprised there was no clearance problems... did you guys run a compression test i wanna know what #'s you got?... you guys use a oem head gasket with that or a 2 ply?

Cams don't cost $1000-$2000 for a set. Even if we are talking about DOHC VTEC cams (B-series, at least), the cost of a good set is well under $1000. The only problem you are likely to encounter with ZC cams is lack of availability. But provided you can find them, there is no reason why they should cost more than a set of LS/B20 cams - about $400 or so. And that's for new cams, not regrinds. The only thing to keep in mind is that you generally need a spring/retainer set. And this typically sets you back another $200-$300 (or so). But even then, the total cost is below $1000.

this is true

look up Crespo cams for the ZC. real good and affordable.
also i would never tell anyone to buy piece of **** stuff. but their zc cams are great and work for a lot of people in the tristate area. i'll post alittle info here some people cant understand what they read so i'll explain whats for what application. the powerbands and specs are on their site.

<u>$365/pair</u>
stage 2 for they are like the type-r cams for the zc. good with FI and Allmotor.
stage 3 for high psi turbo applications..
stage 4 for roadracing.
<u>$405/pair with high lift valvesprings $485</u>
stage 5 for High compression ALL motor.

no where near $1000 and you get valvesprings for $80 more in the stg5kit. you dont need the springs supposebly if you get anything under stage 5. but i would get them anyways and ask if they could add them in on the other kit if its only $80.

i also know WEB CAMS made some nice regrinds for the ZC. and are cheap too.

we used a metal head gasket and took the center out, so it was even thinner. the compression was off the 300psi guage. we estimated it to be somewhere around 14.0-1

SINISTR

I agree - $2000 is probably an overkill but pls remember that Im in OZ, anything from the US is about double just in price + shipping - so a set of $400 CAMS i'll be looking at about AU$1000 by the time I get them.

Im not going to rule out I won't go for something better than a set of regrinds but thats in the future. A set of Biller Cams here costs over AU$800 up to $1200 - thats where my 1-2K came in. I can get regrinds here for AU$350 - just a mild grind whihc should give me B16A hp increase without swapping springs and retainers.

Ive been asking around what is the best profile to fit to a ZC, without swapping valve springs and retainers, with running a stock ECU - but I havent had any positive answers. Cams are usually premade and people can't give me an idea on profiles.

Thanks for the comments guys - hope you can take into consideration the $ conversion and $1000 in australia is about $750 in the US.

they are new cores not regrinds.

i just converted it.

stage2-4 is $497AU
stage5 is $552AU with valvesprings $661AU

shipping is like $274AU to Perth (WA) 6153 from where i live on the east coast, i dunno how much from the company.

just for future renference.

SlobberGoat

You have to factor in govt taxes. We pay approx 20% on TOP of any/all costs above $250au.

SINISTR

these are the Cams from US right? or some made locally here in Australia - in QLD?

PaImportTuner

they are from Florida, US

SINISTR

Do you know what is the best 'profile' to use and still be safe on the springs/retainers?
