What is the best to do first, motor or the FI setup?
What is the best to do first, motor or the FI setup? First off, right now i have nothing but my car ( bone stock 1998 longblock ) a set of untouched 706's, and a healthy paycheck.
I want to go FI because ive never had a boosted car before and ive never been to a single digit ET. at this point, because it will remain a street car ( "street car" used pretty loosely, just needs to stay legal and streetable) for now, im leaning towards a single frontmount turbo.
My questions are these:
Should i build the motor first or the FI setup??
If i build the FI first will i have to change it all after the motor?
the motor built will probably be a alum 6.0 or 6.2 with either reg 6.0 or L92 heads and knowing how we build motors itall be pretty wicked. The turbo will prob be 70 to 76mm with turbo headers ( live in houston, ac is a must )
like i said, ive got nothing at the moment so everything is subject to change, and everything will be very well researched and though out, just looking for opinions. Im just getting done with the drivetrain in prep for this so im like a month away from starting to compile parts.

well i personally havent seen that many cars that retain the a/c. i seen a few on here but i know the compressor must get VERY hot. id do the turbo setup first, for the turbo id go with a 76 or maybe larger if going with anything bigger in ci than a stock 6.0. the lq4 6.0 would be in my oppinion your best stock boost motor. just make sure you replace the rod bolts and use studs. i made the mistake of using bolts and lifted a head.
all hot side parts will be polydyn coated, motor will be fully built- stock block and maybe stock crank, thats where the "stock" part of things will end. 
i am open to SC too, nothing is out of the question right now.

You have several good choices bro. I bought a kit from KYTP and haven't looked back yet... and the kit isn't on the car yet lol. Procharger would require "less work", but I'm a little biased to the turbo scene because I love the performance and sound. Getting a motor built could be done later, that's what I did... Made just a little over 500rwhp with an STS kit, then tore it all down, ordered a "boost" 370 from speedinc and a KYTP kit with a TC78 and now I'm building the WHOLE car lol. I'm also doing a tranny swap from T56 to TH400
Turbo First, since your looking at building a new motor anywayz. i say boost the stocker to around 500 whp and build your new motor on a stand. this way you can still feel like you have accomplished something. and not dragged down by the build time length. thats my plan anywayz.
well the motor will be built by me since i work part time for a performance engine builder. the FI setup will prob be built by me too, since im a welder for the weekly 40 ( more like 60 but whos counting )
Theres 2 things that worry me about doing the turbo first. A i might have to re-do it all after the motor with bigger flanges and piping and that would suck to build it twice.
B ive got a 98, which means engineering flaw oiling in the block, weaker rod bolts, and a few other little tid bits. so im a little worryd ill smoke this motor before the next is built and be up a creek.
Im personnally thinking like JAX04, but i also want the benefit of yalls expireance. that and i just found a decent t3/t4 hybrid, a Super T70.
what do yall think? its brand new, not far from me, but im thinkin it may be too small for the new motor. id kinda like to build the FI setup once but if i can build it pipes wise for the new motor with say a small turbo with big flange then upgrade the turbo with the motor to bigger turbo same flange that would be sweet. im just gettin in to turbos so...........

The trans is a Performabuilt lvl 2. 700whp just wont do it for me so ill prob have Performabuilt or Circle D get in it for some upgrades sometime soon, and the converter is a Circle D stage 2 2C/3C so ill prob have it upgraded at the same time.
So i guess my answer to that is ill build the whole thing for, or easily upgradeable, to at least 800hp.
Now to me "easily upgradeable" means turn up the boost or replace the turbo with a larger one. Having the ability to fabricate my own stuff means i can pretty much do what i want but id rather build the whole system once. if i have to do it twice i wont cry though
oh and ive come to the conclusion that the previously stated turbo wont work because its got t3 flanges on it. so ill look for a t4, then later i can upgrade to a t4/t5 hybrid if need be?
feel free to correct me if im wrong, thats what this thread is for. thanks guys!
t5? ... I think you should deff shoot bigger turbo, t4 at the min. might just change the hot side housing for faster spool now and higher spool later vs buying 2 turbos.
thanks, with any luck i can keep a good steady pace lol
power goals, hmmmmm. well i start by saying my converter is rated at 800whp, and my tranny is 700whp. not installed yet is a Moser 12 bolt, and ill be getting a new DS obviously.

that sounds weird even to me im just trying to do something a little different than years past. something fun and different i guess.
the plan through building the rest of the car was for an all motor setup. thats been that way for like a year, ive recently changed my mind for something a little more challenging. building a turbo motor remains relativly easy but the turbo setup in the car is a different story, especially a street car.
Not to mention, im not building "another motor" im building a full single front mount turbo setup for my camaro. I think i just need to quit screwing around and build a race car of my own instead of everybody else's.....
especially since you can fab your own stuff, id go for the engine first if your at all worried about your stock engine not being up to par. build the engine to handle what you want, then build the turbo setup to support it. i have found its always easier to put the turbo setup on hold then having a blown motor and having to build it when money is dried up becuase you spent it on the turbo stuff. just IMHO of course.
you mention ET's in your first post. id use that number for your goal instead of power, not saying you cant figure ET's from power but ive seen too many 700+rwhp cars run 11's to put much stock it in.

heres my setup https://ls1tech.com/forums/forced-in...old-build.html
The only thing u would have too do for ac is use a c6 manifold.

i love the stance of you camaro on the prostars whats your suspension setup? sorry no help on the tubo build but i would go procharger for less problems. do a 402 w/ a f1 head unit
