I have a 90 GT that's pretty well built and looking for more.
mods:
stock block 331 stroker
main support with windage tray
oversize aluminum oil pan
Eldebrock heads
custom grind cam
GT40 upper and lower
adjustable TB with 75mm inserts
C&L mass air
BBK shorty s
flow-masters
NX wet 150 with bottle heater and Jacobs mastermind controller
MSD diss, 6 box and coil
42# injectors
adj FPR
255lph pump
TKO 5 speed
scatter shield bell housing
center force clutch
aluminum drive shaft
FMS 3.73

all that nets me 320 WHP on a mustang dyno, now I want more with a single single turbo kit, 650WHP goal.

After some reading on here I'm not sure if the block is gonna take it, so question is should I buy a new block and transfer my internals or sell my short block recover some of my money and up the cubes with the new block?

What would be a good short block build for a turbo engine?

I don't like my GT40 intake, whats a good aftermarket choice?

Keep or ditch the NOS?

I'd like to keep cost under $10k, possible?

is your rotating set up forged? if it is not then I would sell the short block set up and start with a good block and forged rotating set up. ADPerformance sell forged aftermarket short blocks for like 4500 range and that is a Dart block and gives a few options on pistons. As far as your nitrous it works real well to help spool a turbo and makes a great intercooler with a hit of HP to go along with it but with the right turbo you really wont need it. I would just stay 331 or if you want 347 would be ok also.For a intake Holley or a carb style intake will work all so I also like the Victor EFI intakes.

my current set-up has all the bells and whistles, forged with ARP bolts and head studs, Main girdle, windage tray, deburred and polished oil passages, made to hold a 300 shot, currently jetted at 150.

Looked at the AD Performance short block and seems to be mostly my current setup with a dart block.

Would the Boss 302 hold up? $1,600 vs $2,400 for the Dart, but with all that extra block it just seems like a waste building it to 331ci, If i read correctly they will make a 427.

But with a 331 setup the extra thickness in the block should be better though I guess, especially if I decide to keep the NOS on it, what would be a good shot for it, plans call for a Hellion Power Systems pipe kit with a Garrett GT42, I hate turbonetics turbos.

you cant get 427 CID out of a 8.2 deck block 363 is about as big as it goes with the 8.2 the 427 is a 9.5 deck block that is a 351w block. 2,400 for the Dart seems a bit on the $$ side you must be looking at a Iron Eagle block by far the best but it is a bit over kill for you. the SHP block is 1699 the sportsman block is 2250 and the Iron Eagle is 2676. But Yes the Boss block is also good but they have a short cly. bore and from what I have seen do not really work good with the 347 kits with the 3.4 stroke but will work fine with your 331. I would just get the good block and use your 331 kit maybe freshen your rings and bearings if needed. 331 with the right setup and a good turbo can make 1000 hp so that should keep you covered for awhile. Hellion makes good kits but they are $$ have you looked into BG turbos kits and Pony Down kits they are nice and the price is good on both of them?

[UGOT8UP]

I just looked at those kits, seem kinda cheap main reason I wanted the hellion pipe kit and cooler is because there stainless and should hold up a bit longer, but if you think the other kits will hold up just fine than no need in wasting money, but I do not like there turbos, the precision is OK but Ive never ran a MP, I've had good luck with Garrett's in the past on my GN, DSM and LSX Camaro.

How good are the intercoolers with the cheaper kits?

Do the cheaper kits have flange warpage problems? do they fit good?

This is my first venture in Ford country so please excuse my general overall dumbness, I got the car from a person who was in a bind for $5,500

BG kits have a super good warranty on them call Brian and ask him about his kits. He is a good guy and I have not heard a bad word about the guy Pony Down I have talked with and they are also a class act call them both and talk with them just cuz you call dont mean you have to buy. I do think the intercooler is a import part while there kits they make BG also sells a import kit but he would much rather sell you his as he will tell you. and the quality is better also. Heck lots of guys run the ON3 kit and most have good luck but I have seen people starting to bitch about them in the last few months. I my self will spend a few more bucks on American made stuff myself but that is me.

I ordered a new MSD dissy from jegs last week new one should be here tomarow, the pickup in the old one came apart, filled the bottle up yesterday so I guess I'm gonna raise hell on it this week race it friday night and tear it down on saturday so I can measure my bearings and bore before I get everything ordered.

I would normally deal with jegs but I would like to support a Mustang dealer, who would you reccomend I order from? engine gasket kit, MLS head gaskets, block, bearings for rods and crank,does the block come with cam bearing installed, cast rings, oil pump and a new cam with turbo grind should be everything I need, might aswell get a new intake while I'm in there.

Gonna go with the DIYautoTune.com mega squirt for tuning, $650 seems like a hard deal to beat.

Gonna call some turbo companies tomorrow ask a few question if i get the time.

Thanks for your help, what setup do you run?

[uedlose]

I run a Cartech outlaw turbo kit with a 80mm turbo and a 306 with a R-Block and a forged assy. it is long rods and custom JE pistons with a C4 and 331 rear gears ported TFS TW heads and a old RPM intake and D/R 275/60/15. I tune with a old EPEC that Ford use to sell years ago. I have been chasing back pressure issues for 2 years and just made a custom 3.5 in down pipe for the thing and have yet to try it out. I am looking for 9s the next time out but I will only get one chance after that I will be asked to leave due to only having a roll bar and not a cage it runs over 135 mph now and the rules say I have to have a cage. It is a real street car and has heat and all we drive the thing all over the place just one of the great things about boost. I have been 10.30 lifting at 1000ft with only a 1.70 60ft so there is a lot left in it I really need to put a trans brake in it but I am holding out to see if it will run 9s without it.

I got the holley systemax upper and lower it works really good. I got trick flow 170cc heads, trick flow stage one and a 70 MM throttle body

[UGOT8UP]

Pretty bad ass setup! I feel you on getting kicked out of the track, me and the track owner where I live are on first name basis, I'm always showing up in a new car that isnt track legal, pisses him off but he smiles about it most the time.

Im 6'2 240# I can't stand crawling in and out of my street cars, it might get me one of these days but so far I'm still kickin.

[UGOT8UP]

2vPOWA I'm going with a Victor intake and elbow, just in case I want to bigger in the future.

[EscortSportage]

Ok... Im running a stock 302 w heads, intake and tb with 4lbs of boost and she moves! 331 plus hci and boost u will scream! With that being said id sellthe nos,

If u want 650hp dont use a stock block ud want a 4 bolt main, dart block
Sell the gt40 stuff. Im running a trickflow trackheat And i like it a big elbow with a carbd lower with fuel injector bungs would be better for hi end and more power depending on ur cam and how high u want to spin

U want 80lb injectors, and atleast an intank aeromotive 340lph pump

Honestly imo i wouldnt worry about cubes ans stroker kits a 302 with boost is ample i would have made 600rwhp if my pump and injectors were big enough (im surprised i didnt split the block on the dyno)

[UGOT8UP]

I'm now considering a coyote swap, read a thread eirler where it can be had for less than $10k. I'm still on the wall though.
