young noob

hey guys, i skipped a couple teeth on the timing belt, and i bent a valve and and i am going to rebuild the motor, im going with a vitara set-up, tt h-beams, but one of my questions is should i stay with my bore, and enlarge it, that is if the cylinders are ok, i ask because im staying obd-2 and am going to run afc hack, and i want a pretty reliable tune, also, i would like to rev to 8k, but where can i get new "performance" valve train? i can't find it anywhere? thanks guys i appreciate it

Run the afc hack? Do people actually still use that trash?

I'd leave the bore stock, so when you blow it up again, you can still rebuild the motor

If you are dead set on the hack, then do yourself a favor and look up MSD timing retard, so you can at least pull timing. Remember, just becuase you are putting in rods and pistons, does not mean you can run stock timing

i can only use the hack because if i convert to obd-1, then im not legal......i'd like to run 10 psi, im happy with that........but i need some actual advice, not just criticism on my fuel management......

Newsflash, turbos aren't legal on your car.

There is currently no solution that allows you to retain stock OBD2 ECU that will allow you to tune the car correctly. Y7 is VERY similar to Y8 in it's very conservative ignition timing requirements... actually, they like a little more timing than Y8, but less than the other non-Y D-series engines. As such, you run the AFC hack that ADVANCES your timing under boost and HAHAHAHAHAAAhahahahaAHAHAHAhaHAHAahAAaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaa I told you so.

You can either convert to OBD1/run a standalone and learn how to hold the wastegate open, swap injectors, and plug back in the OBD2 ECU once a year for inspection... which is at most an hour's work... or you can generally do stupid **** because you think that us criticising your "engine management" doesn't have anything to do with giving you actual advice.

Reread this thread, and pay close attention. You're planning on doing AFC hack and then getting upset when EVERYONE tells you not to, and claiming they're being unhelpful and unconstructive. Uhm, hello?? Does it occur to you that AFC hack = bad idea??

What's the point of staying with the y7 as opposed to the identically priced y8?

because i have a y7 and there is no need for a y8, 200 whp and 200 wtq is all i want, 10 psi doesn't even requiere that, i would like to eventually run it, and you say to plug back in your stock ecu and injectors and such for inspection??? wouldn't you lean your fuel out like crazy and risk blowing it up? and what about emissions? your not going to pass that with the stock equipment?

Reread what I said a second time:

How are you going to blow anything up with that part's configuration?

How can you not pass emissions with the stock equipment?

Seriously, bro, you need to do a bit more research and work on your understanding of how everything works together in harmony before you boost your car. It's not super duper hard, but there is a little bit of work you have to do in order to grasp it all. Keep plugging at it and you'll do fine.

thanks for the advice, but i have a good enough grasp on it, i got it taken care of....i didn't see you posting to hold the wastegate open, i'll admit i haven't heard of that

HiProfile

So you want to try 8k on a head that sucks past 5k, and with 8:1 compression as well? You should try it, I'd enjoy seeing a set of vitaras with holes punched in them.

If you had a good grasp on it the idea would have occured to you.

Your name is young noob and you are asking basic questions. I'm not downing you, we all started somewhere, but you need to be aware of what rung you occupy on the old knowledge ladder... and even more aware of the next rung above you. You aren't going to fly up to the top of the ladder by tapping your heels together thrice, homeslice - start climbing.

No, you sure don't. Listen to J. Davis. He's probably the most experienced person who will be civil to you on this board. I'm keeping this short because I - in opposition - cannot remain civil when faced with blithe ignorance

Good day, sir

i am currently porting and polishing my spare y7 head as we speak

and yes im a noob, im trying to get into the forced induction game, i have pretty good experience with suspension, im also just trying to do some new stuff that isn't typically done, and asking for your advice on here, i don't think what i said is that stupid of a question, **** i'd like to run 7-8 psi and rev to 8k and ill be happy, and i think thats reasonable for an afc hack to handle.......

You are aware that you are supposed to retard timing under boost, as the higher density combustion charge burns faster, not advance it ten degrees under boost?

You seem like a nice guy, but you won't listen to the ONE point that EVERY poster in this thread has commented on. Survey says... you are an idiot.

You ever breeding:

I should have known how this thread would turn out when I saw that stupid JDM crap in your avatar.

You must be one of those fact-fighters with something to prove. YOU WON'T BE GOING TO 8k WITH THAT HEAD. It's $100 ******* dollars for a vtec head - go buy one.

young noob

geez you guys are meanies, i understand i need to retard timing, i never said that i was just going to ignore it.....and i already said that i was port and polishing the head, and i have a buddy of mine going to flow bench it for me, i have a vtec head in the basement, but i need to buy other misc. parts for it to work, and im not sure on this, but im pretty sure y7's create more torque than y8's, and yes, ill agree with you on my avatar, i am totally against jdm, i put that up there two years ago when i thought jdm was cool, its all whole bunch of hype to pay ungodly amounts of money for stupid ****,

Porting the head won't do jack **** for what you're trying to do. If you want to go to 8k (for whatever reason), you need a vtec head with a good cam.


And the y7 is not better than the y8, in any aspect.

young noob

i respect joseph davis's opinion, but semtec, what you are trying to say isn't making much sense, and yes, y7's make more tourqe than y8's, look at the numbers given in the link i posted

bigbadboy

and you also have to remember that no 2 set ups are alike to comparing dyno's is useless. i know someone that got tuned on the SAFC hack and it didn't last long. but hey its your money down the drain do wat ever you want. even with your safc hack we'll see how much fun you have passing emissions

kyden

i don't understand why you want to rev to 8? you're definitely not making enough power up top to support your revs.
