hp junkies - i need advice!!

[dickster]

ok, i've just finished reading "maximum boost" (purchased because of the interest generated by your threads!!), and my brain is ticking away - i have loads of questions!

the book is a bit old but the same things should apply now, right?

i would love to go and buy a kit from todd at protomotive but i aint got that amount of cash in my back pocket and what with all the import duties.....

anyways this book (and you guys) has got me wondering about going alone. i mean with a peak boost of .5/.6 (for around 300hp) it should be pretty simple??

i came up with a list of requirements with the books help

1. turbo - secondhand/recon to keep cost down.
2. waste gate.
3. rising rate fuel press. regulator for increased req'd under boost.
4. maybe better than stock fuel pump (930??)
5. fuel pipe/fittings.
6. air filter assembly.
7. pipe/fittings - filter to compressor and compressor to inlet.
8. fab steel pipe work/flanges.
9. air/fuel meter
10. spark plugs?? (colder)
11. signal supply pipes.
12. knock sensor??
13. oil feed drain pipes and mod lower rocker cover.

i figure us$2k tops - now that i might be able to live with but i dont wanna go in over my head.

it can't be that easy, right, am i missing something?

as far as i can make out i do not have to mess with stock settings other than fuel regulator, i dont think i have to play with ignition with low boost?

why does a kit cost over 5k??

am i over simplifying things here??

what are your thoughts, is it feasible? what components would you recommend for a 3.2 - to help me price it??

[Allenk]

What's an easy way of getting those things off anyway? I changed my bushings and I know I will need to adjust the height once the car is back on all 4's. I had to pull the torsion bars out after changing the bushings once already and it was a lotmore difficult than originally. It near took me an hour to get bushings to let go.

Today is your LUCKY DAY! I have the necessary pipes if you wish to installed it on the "SIDE"so e-mail me and we see what we can do,few things that will SAVE YOU $

Remenber this is based on my previous set up AGAIN,No Intercooler,No Internal Modifications,.5bar of boost NON Adjustable Dyno figures 320hp/277rwhp
ok with that on mind

1)Stock fuel pump did work fine for me
2)pipe - filter to compressor and compressor to inlet. I have if you want to installed on the side
3)You need a chip,I may have that too
4)Air Filter I have but they are cheap
5)Wastegate you need 40mm(mine is sold)
6) spark plugs
7). signal supply pipes. ???
8) oil feed drain pipes and mod lower rocker cover.(easy)
9)Good Muffler not those Cheapy,I may have that too
10)turbo I may have
11)Ignition stock is ok
12)Fuep pressure regulator a good one

Maybe we miss a few items but anyhow this kits can be purchase fro m $5000-6500 Depending were you shop
if you take the on the side kit is $5000 install or it just to be so around $3000 in parts and $2000 in labor (they have to eat too)
I belive that you can do it for $3500 including a GOOD Muffler,I will look my notes and seee what else is missing,
C MONNNNNNNN WE NEED MORE JUNKIES!!!!

juan

thats the set up i am looking into. stock with no mods!

keep it simple - for ME.

i need a chip?? i thought stock ignition curve and fuel is taken care of with pump/regulator??

what does a waste gate run to $$$$??????

signal pipes are the boost signal lines.

i already got a dual out dansk.

i am definitely interested in any spare parts you may have, dont forget i'm in uk though . if nothing else the pipes may save me loads of headache with fabrication....

the protomotive kit is mid 5k just parts, i believe.

would this setup be pretty easy?? i haven't got the technical knowledge to spend hours tuning and refining, although i have a local dyno. i figured if i buy a air/fuel meter i can set the regulator myself.

i love LUCKY DAYS

cheers

[juan ruiz]

The Wastegate will run you $500,(NEW)the chip you can purchase from protomotive or see if mike can help you YOU WILL NEED A CHIP to do all this if the engine if not tired,how many liles she has? mine had 65,000 miles and the valve guides were wear out,so lets see firts if she is a suitable candidate.do you need the emissions crap?The pipes are very light and are perfect fit I will get all the parts and send you a picture with you LUCKY Price +the discount for been a loyal HP JUNKIE FAN

[Glasgow 911SC]

Richard, you trying to justify those 930 calipers?

[beepbeep]

you are not going to boost more than 0.5 bar , right?

My advice is to find used Volvo 850T or SAAB 9000T turbocharger (full-turbo version). Those puppies have built-in wastegates and can be had pretty cheap (cheaper than a new external wastegate). SAAB wastegate is already set @ 0.45 bar so you can work from there. Make your own plumbing, and run w/o intercooler to begin with. Your Moronic ECU probably has closed-loop control and with Progressive fuel-regulator (also something you can buy/steal from a wreckyard) you'll be in <1k$ ballpark with very quickspooled turbo and bags of pleasent torque.

These turbos are a bit small for 3.2 displacement, but should work just fine and have zero spool-up time as long as you don't boost more than 0.5 bar.


Now go to your nearest Volvo/Saab junkyard!

[dickster]

juan

lol, oh yeah very loyal!

mine has 85k, but its GREAT.

look forward to seeing what you've got. what turbos are the pipes suitable for?

chris,

well, i need uprated brakes for a turbo, right? my problem is finishing one thing at a time!

i only intended doing research and then stuff comes along, you gotta take a bargain when it comes.........

goran,

that is exactly the route i was thinking of to keep the costs really low. maybe others would then be more interested.

no more than .5.

sounds like an interesting idea. will it work? the size did concern me. there must be plenty available, which again, is ideal.

are you saying i'll be ok with just the regulator, and std chip??

thanks for the info.

i still dont get why i need a chip??? or is it that the lamda sensor will detect extra fuel put in from the regulator and adjust the mix?? thats a pita.......i just thought that can't be right. the regulator will ensure the mixture is correct, not rich.???

[Glasgow 911SC]

Look here Richard. Is this what you mean Goran? I'm assuming it's not the Aero model!

[beepbeep]

Richard: add doesn't say which car ... turbo can be everything from Garrett T3 to Mitsu TD04-15T.

There is one bad thing with those that i didn't think about: all except Garrett T3 are watercooled. You can plug watercooling but then you need to be extra careful.

- Mitsu TD04-15T would be perfect, but it's watercooled and comes only on Aero-models
Garrett T25 is too small
Garrett T3 could work pretty well (it's pretty big for a SAAB and is oilcooled to boot), especially with Trim60 compressor housing.

I recomend T3, (it's probably one for sale on E-bay)

[WydRyd]

Dude, if you are only planning to do a Stage 1 equivalent (320 flywheel HP) and stick with that, go for a T3. You'll get awesome response and spool up. Just make sure it's capable of flowing that amount of HP However, if you plan to intercool later and run a bit more boost, get a T04B.

You will need a remapped chip and a rising rate fuel pressure regulator. The rest of the components are factory stock (injectors, fuel lines, fuel pump etc).

Is your '86 Carrera a 9.5:1 C/R engine or a higher compression 10.5:1? If the later, then you'll have to lower compression by doing a top-end job. If 9.5:1, then it's just external components

Good to hear you are seriously considering the upgrade I guarantee, you won't look back!!!

[beepbeep]

I second WydRyd, if your 3.2 is a 10.5:1 job then everything gets much more expensive.

[WydRyd]

I believe the 1986 model Carrera 3.2 runs 9.5:1 C/R, so you should be OK to run 0.5bar non-intercooled (or 0.7bar intercooled).

[dickster]

i've got the low compression usa spec motor, which is lower still, 8's?? can't remember exactly (its 5am!)

thanks guys.

but why the chip??

[Siena911]

Hi Richard,

Youre on that slippery slope ( The same one that I fight off every day)

Good for you. Another thing that you might not have thougt about is Insurance. I don't know how much you intend to use the car etc. etc. but my SC with the 3.2 carrera motor is a real pain to insure because the insurers consider this a modification and either penalise or point blank refuse to insure.

It would be a real pain for you to build it and find it is really expensive to insure etc.

Just a thought

Jakes

ps I am going to be watching this thread closely...

[dickster]

chris,

i just emailed the guy on ebay, thanks for that. i checked out ebay a few days ago and found nothing!


jakes,

lol, thats been in the back of my mind! i am expecting to have to change co's, but i'll check it out - thanks for the warning. i don't think the guys in the states have the same problems.


anyone know where i can get a look at compressor maps to see how close to suitable these units are??

ok found this site http://www.turboneticsinc.com/comp_maps/fig4.html

but i have worked out i need around 400cfm at 1.35 pressure ratio. how do i convert LB/min into CFM?????????

ok, got it (love the internet) 10lbs=144.7178 cfm

the t3 60 trim will struggle top end, but the mustang used it!!??

[juan ruiz]

Today is you 2nd LUCKY DAY all you need is a TO4B.58 There you go!

[dickster]

juan,

ok getting excited now.

it seems the t3 was a v popular unit, what about the t4 i need - any ideas what it was used in????

[juan ruiz]

It all depends on the application,people uses diffrent turbo for diffent reasons,is all on that site that you fond.

[dickster]

juan,

yeah, thats all

i've looked at the maps and the t3 really isn't good for the 3.2. anyone actually using it in that application??

the market isn't half as good over here.

what unit will your pipes fit???

i've emailed loads of dealers to find a t4............

enjoying the ride??
