How much horsepower to expect?

[KCz Eclipse]

As of now, my 91 gsx is bone stock besides a 16g. In the next few months, using school grant money , i will be putting some parts on. I have a TBE exhaust ready to put on now, its a 2g ported exhaust manifold, megan o2 housing, PR dp, thunderbolt cat, and an ebay ss catback. In addition to the exhaust i will be putting a dejon air intake on as well as a vrsf fmic, and maybe some 272 cams (still undecided). With those bolt on i will be turning the boost up to about 15-18 lbs, and will finish it all off with a good tune. What do you guys think i will be running with those bolt ons and boost level. If any info is needed just ask.

Thanks

Forgot to add the 190 fuel pump, and probably some 750cc injectors.

[gtrej01]

I'd suggest some upgraded injectors and fuel pump also.

[mattasi]

Yea you need fuel, with supporting mods...200-300whp

[zcox122]

What are you using to tune. And i would say do fuel before cams.

[KCz Eclipse]

Yeah, sorry, i forgot to add the 190 fuel pump, and 750cc injectors. With all that what range of numbers should i expect?

[zcox122]

You can get around 300whp out of that.

Get a good dyno day in with dsmlink. Your probably pushing over 300hp. What psi you plan on boosting to?

[crazyquik22023]

It depends on what dyno you use, dynojet or mustang dyno and how good of tune you have. What are you using to tune with? Dsmlink or just an air/fuel controller? With the list of mods you mentioned at around 18psi and a good tune, you should be able to make 275-350 to the wheels on a dynojet.

What do you guys recommend i do. I just have a motoguys garage ecu, nothing special. I am going to look inside to see if anything has been done to it, or if it is chipable. If it is not chipable, should i get it coverted and chipped? I know nothing about the tuning side of the upgrading, i need some input on tuning.

[zcox122]

Dsmlink for tuning. Its not the stock ecu?

[DSM1G90]

Have to be careful, for these responses are all guesses on here, not concrete answers.

Put it together and report back to us what your results are.

Otherwise, it can head to a bench racing topic.

[KCz Eclipse]

Um...no. I was told by the last owner that the ecu crapped out on him so the motoguys is what he got. Heres a link to another one of my threads.

I would get some sort of tuning solution before you get to carried away with those mods...I would recommend link since there is so much support for self tuners...thats just me ...lots of options.

[boost97gst]

Its all in the tune and temperature at the time of the dyno to be honest. Its coolingoff so you should be able to make good numbers. You will get power-jaded super quick tho lol and want way more. Just get a good reputable shop that knows link very well and dyno tune it. I would guestimate roughly 275-300

[xxNocturnalxx]

I guess I'll play along. 300whp, happy?

[rockysgsx]

I have a 95 GSx and all stock motor with 3G lifters which isnt gonna increase hp but anyways all stock stock air intake with 16G and RC750 injectors along with dsmlink V3 plus 255 pump on 91 oct and all the supporting bolt ons to make a fully built motor go past 500-600 hp mark with 1000cc injectors and now my GT35 turbo i was making around 270-300 hp and that not with the big stuff i mention.. hope this helps but yes there are cars that have made 300 hp mark

[taberj47]

^ i hope u realize 300hp in these cars is not a hard goal what so ever

[Kapok6]

Jackal or werewolf are another inexpensive option for tuning if you have an eprom ecu. It can be found ds-map.net

[danielkile]

with all that 300hp easy with a good tune maybe even 325

[SiNiST3R]

Really hp don't mean a damn thing here.. It would be more like will it run correctly after the mods. Lots of factors blah blah always under guess what you think you will make and thats how much you will make anything past that and it's a bonus. New cars these days out run many DSM I know.

But GL Cheers!

No bench racing in the tech forums.

Want to know how much power it makes? Bolt some shit on the car, tune it, and take it to a dyno....or take it to the dyno and tune it while you're at the dyno- you choose.
