DarthIROC 08-16-2002, 03:54 PM I was wondering If I could get some advice on the most bang for my buck out of my next upgrade.
I have a 305 TPI 86' ROC just rebuilt 2 weeks ago. It was built with the folowing upgrades
bore .040 over
Tri Core Radiator
Shaved Heads (.040 Too I believe) 1.98 Valves with 3 angle Valve Job
HIgh Volume Oil Pump
Headers
Highly Modifies 700-R4 with B&M Slapshifter
3 inch exhaust with Flowmaster
3.73 limites Slip Rearend
I was thinking about adjustible Fuel Pressure regulator or a new PROM chip Im puying for college so I cant spend $1000 bucks on a mini Ram or something. I already have a disk Brake 3.55 posi rear but havent put it on yet post any suggestions you can.

Ucantcme57 08-16-2002, 04:03 PM I would get the Fuel Pressure Reg. and then It's time to look at the suspension. go to PST and buy their 5 way adjustable KYB Shocks I think their 395 for the set of four. Get a new Torque Arm, (www.spohn.net) 395.00 get new LCA's 175.00 plus LCA brakets 65.00 Let's add this up.. 395*2 = 790.00 plus 175 = 965.00 + 65.00 = 1030.00 Not bad!!! and you will deffinetly notice a difference.. et's will go down, you car will handle and launch better. and you will see overall performance gains across the board..
Just my idea thou..

Ucantcme57 08-16-2002, 04:11 PM opss.. Here are some links
www.p-s-t.com (http://www.p-s-t.com)
www.spohn.net (http://www.spohn.net)
and by the way those shocks are adjustable AGX gas shocks made by KYB 5way adjustable and are on sale for 389 not 395 saving $6.00!!! so the end total minus shipping is 1024.. Still not bad if you consider the amount of great performance parts you have added.

AutoRoc 08-16-2002, 06:57 PM I'd replace the intake manifold with something like a Stealth Ram or an LT1 intake(Do a search for the swap info). just my opinion though.
It kind of makes sense to add that after headers, a valve job, and 3.73 gears like you already have. More RPM!! http://web.camaross.com/bb/biggrin.gif

DarthIROC 08-16-2002, 09:24 PM I forgot maybe my best upgrade A Lunati Cam and hi perfom lifters the specs are like 259/271 degrees of lift and .500/.515 duration but I may be slightly off I dont have the summit book in front of me. I also have TRW Flat Top pistons if that makes much difference.
I like the suspension idea but thats more for like 6 months down the road after I figure out my living costs for college hers what I was thinking of now.
A Petronix Flamthrower Kit for my Distributor
Adjustible Fuel Regulator

Bristol 08-16-2002, 09:29 PM Maybe some 1.6 rockers.
DarthIROC 08-16-2002, 11:20 PM I dont want to take the engine back apart so soon so Rockers are out
------------------
I find your lack of faith disturbing
aklim 08-17-2002, 12:03 AM What do roller rockers have to do with taking the engine apart? You can get to them with the valve covers off.
DarthIROC 08-17-2002, 03:00 AM I realized that a while ago and now I feel stupid. For some reason I was thiking I had to take my whole intake system off but O well. Would roller rockers give a noticable improvement I dont know alot about them.
Ray86IROC 08-17-2002, 03:53 AM If you're really packing .500" lift then rockers would be a big fat waste. You already have wayyyy more cam than the intake can support.
I would skip the AFPR, just shim the stocker (use a quarter in the stock FPR) to up the PSI slightly. Then buy a dremel and some bits and port the TPI plenum, runners and base. Or at least hog out the plenum if you don't want to remove the rest. Definite improvements to be had.
I'd be real damn tempted to spend the $450ish and get a stealthram and try it out though...
If you get a chip, get a custom chip for your setup, not some off the shelf POS.

Spend your money on chip tuning software, and any other prts that are worn or needing attention.
Good luck with your ride.

I hope you have some kind of high flow air filter(ie. K&N) at least.
The best bang for the buck is always Nitrous.
You can buy a nice kit for 350 to 500 and cheaper if you go used.

aklim 08-17-2002, 12:10 PM Folks, before we get too carried away, how much do you have exactly to spend?
DarthIROC 08-17-2002, 05:45 PM I dont have any specific set amount to spend I was just saying dont post anything like buy a weiland Supercharger or something I like the stealth ram idea and $450 doesnt sound too bad if thats what it is it will just take me a little longer to get that. Id appreciate it if somseone posted a link so I could to a little research into it. Ill also look into porting the plenum. If I bought a TB could my set up handle the 58mm or should I stick with 52mm.
Also a little off subject but since the rebuild Ive had trouble keeping it cool even with the big tri core out of like a 69' Z28. I had the Radiator gone over before I put it back in and bought a new water pump (although its only stock replacement). I have a feeling the stock fan just isnt etting the job done I took it off the relay so it suns as long as the car is on bit it still runs over 220 more than id like with a 180 thermostat. Do you think a Summit twin fan set up would help or maybe a hi flow water pump?
------------------
I find your lack of faith disturbing
Ray86IROC 08-17-2002, 09:00 PM Get a Stewart hi-flow pump and I'll bet you'll be set. I snagged a stage1 pump for both my cars, drastic differences (I also had new radiator, new hoses, fans on all the time etc and still ran hot with stock replacements). $69 bux will get you the stage1. www.stewartcomponents.com (http://www.stewartcomponents.com)
For Stealthram info go to thirdgen.org's message board into the TPI section and there is a sticky post at the top with all the info on it. Thunderracing, which is linked off the top of thirdgen.org sells it, for around $450 complete.

aklim 08-17-2002, 10:12 PM Forget about the AFPR because it is a cheater system. Problem with it is that it increases fuel throughout. Even though you ported out the intakes and what not, the airflow increase from one rpm to another is not lenear. If you want low end torque, I would use the Superram. Try calling ACCEL DFI and ask for one of the reconditoned units. Those are units that are returned to Jegs or Summit because of this or that reason. Then you can buy them real cheap. If you want high end HP then go with the miniram. There is no free lunch. You cannot buy a $100 system and expect to have it work as a $1000 system. Bottom line is do you want to spend $500 and then kick yourself later because "If only I had spent the extra $200 I would have got twice the gain, etc."
Go get your prom optimized. From www.fasterproms.com, (http://www.fasterproms.com,) it would cost $500 after you are done. After that, if you need to upgrade it because you changed your heads, cam, intakes, etc, it is $150. They burn you a prom based on your setup. After you run it, you send them readings so they know what the car is doing. They burn you another prom and keep going till they get it right. I have had many more mods than you mentioned and they got it within 3 burns. Since I was a previous customer, it cost me $150. The off shelf performance chips just give you a little more timing or turn the fans on early. Waste of money. Also not customized.
OTOH, you could burn it yourself if you are willing to mess with it on and on till you get it right or blow up your motor. DIY is great but if you don't know what you are doing, it is a long drawn out process. In less than a month, I can have my car running perfectly vs constantly mucking with it.
DarthIROC 08-17-2002, 11:38 PM LOL Ok Im getting a whole lot a Rams thrown at me here I saw the Mini ram for $900 from TPIS and dont really have n idea what the super ram and stealth ram really are.
Aklim just so I have this straight your saying to go with a miniram or superram and these other guys are talking about the stealthram whats that. And with the super ram would I need extra hood clerence or would it fit under stock hood.

86 IROC 08-18-2002, 09:40 AM Everyone is suggesting this guy intake manifolds... but it's a basically stock 305 with a cam from what I gather. The stock TPI with some home porting will more than suffice for now.

Below is the Superram

Below is the Base Manifold
http://www.lingenfelter.com/lingenfelter/product.asp?dept%5Fid=16&pf%5Fid=41
The Superram is for better low end torque and the Miniram is for better upper end HP.
I know for a fact that the Superram kit works excellent for my 350 which was stock and fit without too much trouble. Like I said, contact DFI and they may have some return units that they can sell for a killer price.
You get what you paid for. The stealthram is a cheap unproven system as far as that goes. The Superram and Miniram have been around for Eons. It is the ideal dream to get $2000 worth of performance for $500 but not in this life. Word to the wise, Spend wisely.

True, True. How about in the future? You either spend money and have someone else port it or spend a bunch of time DIY. Either way, time is money. Why spend time on something that you will outgrow in a while. Besides, he does have a cam and may get heads later on.
DarthIROC 08-18-2002, 05:34 PM Well I would rather like a '69 302 or something to work, but the engine isnt just stock its bored .040 over and the heads are shaved plus I dont know what the stock heads had for valves but the heads I have on it have bigger valves maybe 1.94's but I think there 1.98s. By the way not to sound like a ricer but how much would one of those rams eat away at gas milege I do drive this everyday. Its not all that big of an issue though as long as it doesnt knock me down to like 5mpg

You got ripped, I was talking about adjustable 5 ways, It's just a 305 so another intake or supercharger is unnessecary, With my stock 86 I was burning the tires, I would rather have traction and whoop ppl cause my car takes off like a raped ape. If you are going to buy a new intake get one with the highest RPM value. It sounds like you want to get t supercharger you don't want to run out of air cause your intake won't support it. get one with a high rpm value, stock = 5500 miniram = 6250 superram = 6500
