lx ecu not familiar with miata cams?

[bp_turbo'd]

my bp was rebuilt with 99 miata cams and solid lifters i was wondering if its because ecu doesnt kno i have these cams? my low end power is still missing
do i need to use miata ecu? whats difference between bp and miata bps?

and othr question do i have to torque the head again? i ve been notcing oil leak between head and block here and there

[therieldeal]

are you boosted? what turbo? boost level?
what cams did you have before?

[Henchman]

Did you check the valve clearances?

You didn't reuse head bolts did you...

[therieldeal]

it sounds like someone else rebuilt it for him

[bp_turbo'd]

he rebuild it and sold it to me, i guess he couldnt get it running right and we got it closely and sounds perfect and theres low end power missing i just kno i could fix the problem though

[therieldeal]

do you know if he shimmed the cams correctly? its a huge pain and far from being a drop-in swap

There is nothing wrong with re using head bolts as long as they are within the factory spec. Thats what i've always heard at least and I have reused head bolts several times in different motors with no problems

It's dumb, because they are TTY bolts. I'll laugh if you can show me some FSM specs for reused head bolts lol.

Well it says in the FSM that you can reuse your headbolts if they are within some specs idk what they are of the top of my head but im pretty sure it says something like that

ok im in the prossess of buying another bp engine. i read this page http://web2.airmail.net/theman/prote...ml#miataengine and it says i can use the 99+ miata cams but have to switch to solid lifters. has anyone attempted this or have a link to web sites that people have done this. how hard is it to do and what exactly would i need? would i have to reprogram the computer? also i will be putting in high comp. pistons and crowler rods. will the crank be a dirrect fit?also where can i get racing springs and lifters. i dont want a race car just a bad ass daily driver that can whoop ass.

sounds like i have to reprogram my computer?

Damn. Diggin up a post from 5 yrs back? Hell I was still a relativly new noob back then. Lol. No you don't need to reprogram the ecu.

[bp_turbo'd]

then what do i need to do to tune and make it run right, or chipped ecu whatever its called

diggin an old thread to see what yall experince was wit the miata cams and trying to figure out what my brother jeremy had been put in this motor tho. I dont even kno if he swapped the whole miata valvetrains and shims?
man it getting better alittle by little man i couldnt rev more than redline cuz theres damn limiter but thank god cuz its still fresh motor tho i did a compression test on it

#1.125
#2.125
#3.110
#4.120

i broke one sparkplug and havent set the tps yet and scan for cel

[therieldeal]

that is some lowwww compression

[mx-3_4evr]

that is some lowwww compression

Welcome to my world. My highest was 125psi. Sorry for the thread jack.

I don't think your problem is your cams. It looks like its the motor with those low ass comprtession numbers.
