92 typhoon exhaust question

[glennz]

customer car, 92 typhoon, basicly stock at this point

motor is blown and in need of rebuild,

lower half recon rods, 10/10 crank, arp rod bolts, forged pistons, balanced rotating assy

heads, stock, gasket matched intake and exhaust ports, and bowl blending

cam comp cams 412 everyone talks about

fuel, cusomer bought accel 35 lb injectors and wants adjustable regulator

slightly larger then stock convertor around 2000 rpm range ???( what is stock...1800 or so)

he wants to run some sort of header set-up with turbo, i have not come across any vendors in my searches

my specific question is who makes headers for this combo, and is there any other items i may be missing in this build, strickly a daily driven street vehicle

thanks in advance

Re: 92 typhoon exhaust question

Get some Eagle rods,Total Seal rings.Stock converter is 2100 stall.You will need a Walbro 255 fuel pump,and a chip to control those injectors.What turbo?

ATR and Kenne Bell used to make headers,but they don't anymore.AFAIK you can't buy new single turbo headers.

JESUS CHRIST ALL MIGHTY !!!
you do not neeed headers to make these trucks run . first thing is to build a strong bottom end . then tune to a safe amount of timing , boost , fuel. all the engine entearnals (sp)do is make sure you don't blow it up . search feature is pretty handy if u want to find stuff

Re: 92 typhoon exhaust question

If I remember right there's people in the 10's running stock headers so they aren't as important to a build as it would be to an NA motor

Re: 92 typhoon exhaust question

Nolan ran 10.7X on stock manifolds and crossover. Tell your customer that headers A) are expensive if you can find someone who wants to sell theirs, B) will most likely crack and require frequent repair, and C) won't yield much more power, if really anything.

Re: 92 typhoon exhaust question

here is the story as i recieved it,

original 92 motor went south, someone installed a vortec motor in place, vortec to much compression for turbo blew again...

from my reading here if it is indeed a vortec long block then modification would have been done to lower intake and heads, could be a vortech short block with stock heads, we will find this out i guess when engine pulled

i did not relize the stock convertor was 2100, with the 412 cam, would it benifet me to run a 2500 stall or stick with stock...

the turbo is stock unit from my knowledge, allthough owner says it does peg out his 15 lb boost gauge...

I believe the only dif is that we have nodular caps (n stamped on them) but I haven't had to crack open my motor yet personally so this is all memory im going off of.. just do a search adn you'll find all the info about the differences.

can't help with the cam\stall question but the stock turbos do still put out in the early twenty psi range.. there's people on here doing so mostly with a 3bar chip and alky injection though so you can't base it being a stock turbo from it pegging 15lbs

Re: 92 typhoon exhaust question

basicly why i started this post was i had looking for non existant headers

but then i was looking at the micheal renz web site where he states you have to modify the heads and intake to use a stock intake to vortech heads, not knowing if this mod had been done or if it needs to be done, or if the last builder used the stock heads on a vortec block

i think i am going to find out a lot once i remove motor and start going thru it, then i may have more questions, i have built a bunch of stock type 4.3 slightly modified, but not a turbo versions as of yet,

but not sure what the big differneces were between the 92's and the newer vortec motors besides compression


the guy who did the last motor may be blowing smoke also, he had told my customer back then it was a crate vortec, so if modifications needed to intake and heads i am not sure he even did that

Re: 92 typhoon exhaust question

pulled motor today, it is indeed the correct motor for the truck, so someone pulled a fast one on my customer, said they swapped in a newer vortech, but the casting numbers are correct for the year and truck..which is good for me anyways.

i am going with the 412 cam, some gasket matching and bowl blending on stock heads casting # 14099067.... block casting #'s 14099073 , forged pistons, balance the assy.

does the 14099073 block have the Nodular main caps

do you guys think i would benifet from going up a little on the convertor, someone mentioned 2100 was stock, thinking of adding 500 rpm or so

what do you guys run as total advance with the combo i have going...

As somebody said above, the nodular iron main caps will have the letter "N" stamped on them.
