Thanks for all the advice. Since I already have a 14cm waste gated exhuast housing just gonna go with a 60mm compressor, a set of injectors, some pump tweekin, new aftermarket exhuast manifold and already have 4" exhaust system...

don't rule out the P/S intercooler and the 3in cooler tubes thet Tim Worline makes.

they will help a ton in keeping the EGT's cool when towing.

Go ahead and do a 366 spring also it's a cheep upgrade and will let your pump fuel all the way up to 32-3600 rpm's. (better top end). $20.00 or so.

you don't need to crank the star wheel down or the smoke screw in all the way. (this only makes her smoke in a low boost excelleration and with a 5 spd in will be worse).

you can play with them after your done with your mods and find the sweet spot, thats called tuneing your AFC.

more smoke is (NOT) more power on a street truck.

The 60MM wheel and a set of 90hp SDX or LBD sticks with the pumpupgrades and a 3600 spring makes for a real nice streetable truck dont waste the money for a P/S IC or cooler tubes or exhaust manifold now to all you other guys I do not oppose those items but for a mild expensive street truck those things to not give the bang for your buck like other items unless there free

now if you want a street/strip truck or a dyno queen then i fully recommend those things

we can make a 1st gen run like a striped ape with pump tuning, 366 spring, mild injectors, turbo up grade or a HX35/40, timing, BHAF intake, exhaust, and a set of 60lb springs for about 1200 bucks that will make you smile, beat most all ricers, and tow like a dream, with LITTLE TO NO SMOKE which seems to be the big issue these days with all these kids running around wanting to make there trucks smoke like trains and what not

thats my $.02 some will agree some wont

Thanks for all the great advice.. I haven't bought the aftermarket exhaust manifold yet but have heard so much about the stock one cracking and breaking studs and for the I/C I dont have that either so that is on my shopping list also. I liked the ford power stroke I/C, looked like it may be easy to mount with the cast on ears.
I want good reliable power but not crazy power and sure dont want roll the coal as they say..
I like that phrase from Big bad diesel DYNO QUEEN. Cracked me up...

I hear ya brother, the dyno queen was cute. My old girl was used and abused by me for years till I came here. Mine is a DD and towing rig. i'm slowly making mods to improve that without killing my mpg or rolling coal. I plan to install a larger turbo, I/C and tubes in hopes to help with my EGT's. Although I will build my 4" exhaust first. I already have the BHAF.

For anybody that cares about towing EGT's ( I tow heavy and DD)

My truck could melt a turbo ( 1600* was just a mile post on the way up) God only knows how high it would go, untill i did the 60mm, P/S intercooler, and 3 inch cooler tubes and it cut 300-350* off my max EGT.

thats an inpressive amount in my book, and 1200* is all i can get out of it, now i don't even look at my pyro anymore.

how much weight you hauling farmboy? I'm not usually over 8,000 lbs. But I would like to include a turbo upgrade, p/s intercooler and 3" tubes on my list. Are you still running the stock exhaust rotor or did you go with a smaller size (16, 14, 12)?
