I used to be a big camaro guy, and back in 2000 I switched teams and got into the mustangs. I KNOW, I KNOW!!!!

anyways, I am sort of back in the same 92 z28 I used to own. I am in the process of a major build-up for it, and since I have been out of the chevy "loop" for 7 years, I am kinda lost. I need some help and info from experienced people.

here's a small break down on the build-up.
stock block... .030 over
stock crank and rods
trw forged pistons
zz9 cam w/new lifters
TF G2 aluminum heads with a very slight port and bowl blend.
TPIS mini-ram
150 shot NOS (compucar wet)

my question"S" are

1) what size injectors should I use for this combo, and will the ford injectors plug right in?

2) what spark plugs should I go with, and set the gap where?

3)will the fuel lines not just "hook-up" to the mini-ram with the supplied hard lines from tpis? If not, what do I need? The lines I have go from the back of the intake(return line and regulator) to the front, right where the throttle body bolts up.

any other info you might want to add, please do!!!!

thanks for the help.

I had this very combo on my L98 before I went up to my stroker. I ran TF 23* heads and had a 1.6 rocker on the intake and 1.52 exhaust. I put down 312 rwhp with that combo on a RICH tune. (more tuning would pick up at leat 10 hp I would think) But to answer your questions,

1)Ford SVO injectors plug right in, might want to get some new GM O-rings from the parts store though, my SVO's O-rings dident fit well and leaked a little bit, after I swaped them to the GM O-rings they sealed. You also wont be able to use the GM retaning clips. The SVO's dont have provisions for them. I ran my LT1 24# for my old combo.

2)I would run the recomended plugs that the G2 heads call for as a starting point. Run about a .035 gap or so.

3) If you get TPIS fuel line kit for the Camaro its suppost to bolt up. I however got some sawnag to -6 AN fittings (for the stock hardlines from tank) and made and ran my own fuel lines.

Im sure you already know your gonna need a new "chip" for all of your new mods. I would stay as far away from TPIS stage V chip as you possibly can. Go with someone like Ed Wright from fastchips, or learn how to do your own prom burning.

 

I agree on all points (even though my MR isn't installed yet, but I use the SVO injectors with my SR....)

Definitely need to get into the promn burning part!

 

Randy92z,
what did you do at the track for times?

I am thinking about a similiar combo.

 

I never really got a chance to run at a drag strip. I was in Germany at the time, and with the F-body club I was with over there we would go to abandioned airfields and set up a "track" if you will, about a 1/8 mile. All us American Army guys would invite the German guys and there Camaros, (they really seem to like 2nd gen Camaros) and we did bracket racing. I dont recall getting any times from it though.

 

ok guys, I have some injectors, and I have talked with tpis about some things.

I have a clearance issue with the t/b hitting the water neck? can I just cut the nipple off and plug those coolant lines?

what does deleting the EGR do?

thanks for the help

 

Yes you have to. I believe the Miniram instructions say you have to cut off the TB coolent ports. I went a step further and had my buddy (a machineist) mill off the entire coolent portion and just left the IAC housing part there.

So what exactly did TPIS tell you? Sometimes I wonder about thoes guys, and dont expect to get any kind of "customer service" out of them.

You dont really need a EGR for a performance application. I dont think they really had a good place to put one on the Miniram anyways. Durring part throttle cruise, it introduces exhaust gasses back into the intake to cool the combustion chambers, so really its not a bad thing for daily drivers.

 

Like Randy said, the TB has to be modifed to clear the waterneck. TPIS did mine wile I waited, I must be one of the few that has gotten customer service. A cam with a fair amount of overlap will give you buit in egr.

 

I was planning on TPIS to burn my chip since I am using there mini ram. Are you saying that I will be disappointed with there chip burning. Did you have a bad experience with them or something?

 

I havent personally had them burn a chip for me, but others that Ive talked to say they just tune the WOT part and thats pretty much it. Sure they do other things like turn off the EGR and whatnot, but the "others" have been disappointed with there chips from TPIS.

NO ONE can get your car tuned in one chip, period!! The best thing is to go to a local speed shop (one that does dyno tuning) and have them tune it for you. It would have cost you $500 for a TPIS chip, and I think most dyno shops charge about that price anyways, but your car will run tons better than a 1 time mail order chip. Just my .02c

 

If you can, find someone local to come and tune your car. No mail-order chip will ever produce as much horsepower as one that's tuned on the spot. Check out the DIY prom boards. They'll tell you the same thing.

Even if you tell TPIS what modifications you have, every engine is slightly different. So even though their chip will be customized to your mods, it will still be a generic tune. Does that make sense?

 

I know it is better to have it tuned on a dyno. Its just that I heard it is hard to tune the mini ram so I thought since tpis made the mini ram that they would know best. There is a shop called Speed Inc by me that is very well known, I think I will take it to them for my tune. Thanks for the info guys it helped me make my decision.

 

I used to live in Elk Grove but never dealt with Speed Inc. I did deal with ASSC in Highland Park and they were very good. Not sure if they're still around or not.

Good luck.

 

I moonlight at R&T's Unlimited in Peoria, Illinois. I have tuned several miniram setups, with excellent results. The best results I had was with a car using one of the TPIS cams and the miniram. The owner of the shop is Rob, here is his contact info

1100 Falcon Ct Unit B

Peoria, IL 61614

Phone: 309-683-3566

Ask him about the green vette with a minram. That car was just plain bad.

 

DAVECS1, which one of TPIS cams was he running? How many cubes? Just wondering?

 

It was the ZZ-409 cam with 195 Afr heads 1.6 RR and a 383 short block. It had a vigilante 3500 stall. I just wanted to take that car home with me when it was all done.

 

dave do you know anyone in teh lake county area that can tune a 3rd gen? im having a hard time finding a shop that can do a dyno tune for me unless i buy all the programming equipment myself.

 

ajk511 - Talk to these guys. http://www.asscracing.com/index.phtml

 

Sorry I do not know anyone in the Lake area. IF you do make it to R&T's I carry all my own equipment including a calibrated WB O2 sensor. You will either need one of my modified memcals. Or you will need to supply some sort of chip carrier. You might want to try the suggested link by ajk511 for someone close. Don't be bashful with these shops. Be friendly and be upfront about your budget. If they cannot do what you need done for the price then they should respectfully tell you that. If they do not or are rude about your budget, run the other way. A customer is a customer, a good shop will work with you and explain cost. It is your pride and joy and you have to live with your car and the way it drives, so do not let someone put there hands on it if you are not absolutely confident they can finish the job. The last thing you want is thousands of dollars of useless metal because joe bob read on a website how to tune EFI.

 

cool cool. I might just try and bring it down to R&T's when its time just to have you do it lol. at least that way i'll know its done right. and when it comes to my baby no distance is to far to go.

 

Boy, that last statement sure is correct! Been there and done that one, don't need any more of those T-shirts!

That's what convinced me to start trying to learn how to do this myself.....
