which turbo setup is better

[dsmmike0505]

ok im looking for around 350 to 400 hp i am building my bottom end and i dont now witch turbo setup to do or what fuel up grades to do what is a beter turbo the evo3 16 g or 20g or t3t4 setup and what fuel injector should i use and do i need a safc controller thanks for the help

I would deffinatly go with the t3/t4 setup. They are pretty cheap; Bullseyepower sells them for around 600. A fuel management system would also be great but not nessasarly need to just get you down the road if you already have at least 550's.

what tubro is good from bulls eye

FP3052 or 3065 would be a great turbo for your set-up. It would also allow some growing room in the future if you wanted more HP.

if money is an unlimited supply. work on your engine internals, low compression pistons and all new bottom end hardwarez like you probably are! oil pump, water pump etc., head bolts made for excesive pressures. and then you should be able to slap any turbo of you choice pushing out 20+ boost. Buy a nice fuel pump megasquirt or w.e you find that puts out some good LPH. Engine managment system, 550 fuel injectors. look on ebay, theya re in evos, sometimes you can get them cheap from evo guys updating there stuff. Update all your fuel lines to thicker braided wire for more output flow. Get nice 2.5-3" IC piping, BFMIC, big fmount intercooler, Buy a header-style turbo manifold with equal length piping for equal expansion into the turbo from each cylinder. Unless turbo kit comes with other header. Work on the internal to prep for 400hp. SAFC would be nice to control it.

What is your goal in price, give me a price and I can make a punch list.

Do you realize that he has a GST. There is alot of bad information in your post, atleast for a car that is already
turbo.


Also to the OP why spend all that money on building your bottom end when your stock internals will handle that just fine. You could be spending your money else where, like more bolt ons.

If your looking for 350hp + start looking for 650cc injectors or bigger. This will make it hard to tune with a SAFC so I would just start saving for DSMlink or get a keydriver chip.

First of all, hes building a motor. Did he ever say that the old stock parts were good or even say what the mileage was on the motor?? No. So i am assuming he needs new everything and pardon me for telling him the things i would do assuming again that his 91 gs-t would ahve a lot of mileage, heck its 17 years old, and his profile states stock,stock,stock,stock. When i had a GSX back in 99, i did take the stock manifold, turbo, IC piping, BOV, oil lines and everything off to buy a new kit. I updated all the fuel lines because stock ones do rob fuel pressure. I remachined the head and replaced the pistons, rings, rods and whole bottom end, fuel pump, and injectors to prep for 25 pds boost. not to mention the time and money i spent on the GReddy EMS for tuning new turbo.

How are you going to say use all the stock parts to make 350+ hp. hahahah. If he jsut used the stock everything and threw on a huge turbo, he still wouldnt get close to his goal unfortuantely. I dont care, stock gs-t or not, if he wants to boost his horsepower by around 150 hp a turbo in place of another wont do the trick, and if it does, other things must be upgraded too.
depending on what his internals are and if the "stock" ones can apparently hold that much boost. If he does still ahve nice internals, then poop on me. I take someone stating im rebuilding motor as "Old motor, needs new things" especially bottom end includes crank, rods, bearings, etc.

All things asside. I hate when people just say .."Slap a bigger turbo on it" not that anyone is saying that but...to efectively reach 350+ hp...stock is not the option unfortuantely and if it was, the car would come with 350 hp.

dont forget to do tranny work to, id be amazed if 350+hp doesnt glaze your stock clutch to mush.

I wouldn't build the engine for only 350-400whp. If you have access to E85 (meth injection could probably do it too), the E3-16G can easily do 400+whp (Dyno Jet) with 272 cams & a stock intake. I got 340fwhp 380torque on a Dyno Dynamics (reads much lower than Dyno Jet) on stock cams, stock unported exhaust manifold, and SMIC.

The Bullseye turbos also look pretty sweet to me -- look at the 47 or 50 trim. You could also check out the Holset HX35/H1C which can be had fairly cheap -- they wouldn't put them in diesel trucks if they couldn't last pretty much forever.

Get a Keydiver chip, or better yet a chip burner to do it yourself (1G's have tons of EPROM editing info). Then just go with 850cc injectors since smaller ones aren't much cheaper anyways (10-20 bucks). AFI posts injector sales here quite often and they are really good deals.

iam looking to build the bottom end and buy a tranny from shperds but i have a limit of 3000 can i do it with that

 

[joe sobo]

i think that if you hp range is 400 or lower, i would only do a stock rebuild on the bottom end. ne need for all the goodie bottom end parts when stock internals can handle well over 400hp. i also tell you that like stated above, you can put the money more where you need it than internal parts that in my opinion would be a waste of the money......unless you will be like me.....once i hit that 400 mark, i wanted more

 

[andy4g63]

I would get Bullseye Holset HX-35 and built a bottom end/ not with stock parts/. Some 880-1000cc injectors should be more than enough. You MUST have some kind of tunning device !!!
-You won't be able to get Shep's rebuild with this money, but after you buy turbo and injectors and EMS, you 'll have to buy bottom end parts and machine and assemble the block. If you still have some money left, I would call Dog Box Racing and have them rebuild thr tranny. Their RACE build is around $ 1200-1300 and they do excellent job. I strongly suggest, that you buy only BRAND NEW stuff, not used, so you buy only ONCE !!!

 

[jrohner]

If your engine is shot, then yeah go ahead and get some good rods and pistons. Might as well since eagle rods and wiseco pistons could be had for around 700 total.
