Ok so this month im installing a turbo kit on my 98LS... the kit im buyin is coming with a t3/t4 57trim... thazz wat the discription says... my question is what size injectors should i use to make good power... i have a skunk2 manifold and Brain Crower turbo cams.. everything else is stock including internals.... i might go with a street tune first depending on money...

hmm. i'm planning a turbo build soon also. What are your goals?? I would go with RC 550's.

my friend had forged piston in his gsr, turbo'd with 440cc injectors. made 268 hp on 10lbs

yeah you could go 440's too, just depends on your goals.

since the block is going to be stock im lookin for atleast 250whp... im planin to get a 2.5inch exhaust since im runing low boost...also upgrading the springs and retainers in the head with the super tech ones which are not that expensive..they work well and can handle 9k

But what about the rods?

If all you want is 250whp you can keep your car stock don't need cams or intake manifold.

Intake manifold is a plus though.

i will be building a seperate block later on because i originally planned to go all motor and i got h-beam rods and a sleeved LS block but i want to boost the engine in my car now since its running very strong wit only 80k

makes sure you get a bigger fuel pump with those injectors

This thread would be better in Forced Induction....MOVED

You'll get a lot better answers here. The Integra and Civic forums are full of crappy answers and terrible misinformation

im spending about $1000 on an ebay kit but i will slowly upgrade the parts.. im just trynin to be boostin by the summer... and im willin to take my time and make sure i do everything properly

i have a 95 ls turbocharged and i was runnin 330's for a while dude it made 254 hp on the 330's with a walbro 255l fuel pump, with that said you could run 330's if your tight on money or what i recommend doin is going with the 750cc injectors (if you have engine management) because they can be de-tuned to whatever you needs are and if you ever decide to build your engine later you wont have to buy injectors anymore and as long as they are saturated you dont need a resistor box either but 440's are good to dude, by the way ive still got those 330's if you wanna get em just hit me up.

damn..just noticed you said your spendin a thousand on an ebay kit.. i know a spot that will give you the kit and installation for like 1300..just figured id throw it out there..

2ndchirp

What spot would that be? Im located in philadelphia

Seeing you have a ebay kit you are probably on a budget. The budget crew seems to recommend dsm 450s which can be found pretty cheap. I've never ran them and I think I read some people have had problems using the freeware ems systems while tuning them.

If you want to do it big and plan on maybe boosting 350whp+ in the future pickup a set of bosch 1000cc injectors. If you have a good ems like hondata s300 you can tune them to run like stock and have room for a bigger setup later.

The reason I say go 1000cc is I went with RC 750cc injectors since it was the biggest saturated injector at the time. Ended up having to sell them a year later when I went for 500whp build.

^ So true!

damn..nevermind your way out there, but anyway spooled has got a point but with a 1000cc injector your gonna need a resistor box too..and if your doin an ebay kit then chances of you building a 500whp engine is pretty far away.. i would personally start to piece a good kit together( patience dude) instead of an ebay one..no im not doggin any ebay kits ive known some to last for a while but ive known some to break really really quick..like 4 months at 7 p.s.i i have a turbonetics drag kit and its been on my car for about 3 years now without havin to replace **** man.

i also heard i can get a used greddy or turbonetics kit for a good price but would it be a good idea to buy a used kit?

I have almost the same setup except built bottom end also. I would also say go with the 1k's. Good luck with the build.

i9 had a buddy get a used kit for his sti. i know its not an a honda dont bash me. but he said the first thing he looked for was to make sure that the shaft does not have any play in it. he has it on and tuned with 400 to the wheel and it runs like a champ.

2ndchirp

o ok... ill look into suttin like that or just put a kit toghether

andiamo23

sorry been busy for the last couple of days, anyway everyone has there opinions but i would rather go with 750's but thats just me..anyway if your gonna buy a used kit just make sure the shaft doesnt have alot of play on it..

Put a kit together, that way you can get good/reliable parts. I wouldnt even think about an ebay kit. With that aside, my numbers are in my sig for a completely stock LS and i've been using the DSM 450's for 2 years now with a walbro 255 fuel pump. If you're on a budget you can find these for a good price. Plus my numbers are with a 3" exhaust as well which helps with the power/spool. Do it right the first time and go 3" instead of the 2.5". It'll help down the road if you want to upgrade.
