Hey all i have a boosted gsr with wiseico pistons and eagle rods. i made 288whp
.60 trim turbo. 2.5" dp/exhaust 11psi.

I seen most people with pistons and rods running 14psi and making 350whp.

before i put in pistons and rods i made 230whp on 7-8psi.

Im tipping out i think my mechanics tricked me. gave me really low numbers before the build, and when i bought pistons and rods they didnt even install them and they just cranked up the boost to 11psi 288whp (right where a bone stock motor should be)! Am i tripping out or is everyone else on here exagerating?

my mechanics said that they knew a guy who cracked a stock sleeve making 300whp and 230tq in his boosted ls. so they kept me under 300whp and under 200tq to make sure i wouldnt crack a sleeve. i also think they kept in mind that i would be smashing on it daily. HELP!!!!!!!!!!!!!

 

Depend on what kind 0f 60 trim turbo you have. Do you have the t3 60 trim turbo or the t3/t4 60 trim turbo? Turbo specs? What AFR the car was tune at? Alot of things can be involve. Number is good if it is a straight t3 60 trim turbo though.

 

just because you add pistons/rods doesn't mean you make more power dude, just means its safer to run more boost. and stock sleeves will hold much more than 300whp

 

but can i run 300whp without stock sleeves. i see all these people running 320-350whp on pistons and rods and my tuners decided to stop it at 288 on 11psi. i heard you could push a bone stock block to 12psi.

 

i have a big 60 trim

 

who is doing the tune, maybe he dosnt feel safe going past 11 psi

 

maybe, but it seems as if EVERYONE is making better numbers than me.

i looked at a thread that said post your turbo hp numbers. and i looked at everyones partlsit and EVERYONE with turbo was making 240-300 on bone stock motor. everyone with pistons and rods were making 320-400whp. and the guys with sleeves were making 420-500+

 

what compression ratio are you running? i have seen 400 on stock sleeves with a very good tune. i ran low 12's at 116 on a stock gsr with 10 psi off of a 60 trim. to trap 116 on slicks i had to have over 300whp. my guess around 320ish. i ran on a base map. i never got tuned like a retard. get a good tune and enjoy your mild build.

 

288whp on 11 psi out of that turbo is perfectly fine. Can the boost be turned up and you can make more power, of course. But the power you are making at that boost pressure is perfectly legit. Having forged pistons and rods does not make power. In fact at 11 psi a stock gsr block in good condition will make more power due to the compression.

Your mechanic/tuner is doing fine. Don't get hung up on dyno numbers. Enjoy your car and if you really feel like you need more power have it retuned for higher boost in the future.

 

i have the feeling my mechanic cheated me out of money. gave me 230whp for my turbo setup. and once i forked over the cash for the pistons and rods than he cranked up the boost and tuned it at 11psi 288whp. it should have made around 280whp in the begining without pistons and rods. now tht it has pistons and rods i should be pusing 14-18psi and maing like 350-400whp. i think my mechanics hoped i was dumb and just tricked me and pocketed all the cash for the pistons rods and labor. all is seems liek they did is crank up the boost.

b18c1 engine, type r replica intake manifold, log exhaust manifold


is there any way i can check to see if they really installed pistons and rods on my car without spending a grip of cash for labor?

Just remember that dyno is just a tuning tool. Dyno numbers doesn't really means anything without some track times to back it up. I have seen some car making more than 350whp+ on the dyno and they can't even get the car to break into the 12s.

Take off the head of you really want to find out. That is one reason why I built my own car with some friends you can trust.

IM shure your mechanic stole your extra 40whp for himself.

Stop whining..... and post your whole setup, cams, type of manifold
etc

 

pull the head

 

dude, re-read all the replies in this thread and take a valium.

 

fi your that worried about him ******* you, then take of your oil pan and see what rods are on there, your stock rods will say P72 on the bottom of them. if they are aftermarket rods then they probably won't say **** and the rod bolts will more than likely say ARP on them or what ever rods you got name... and you'd be able to see the bottom of the pistons. most aftermarket pistons say the brand on the under bottom of the piston, you'll be able to tell also cause they'd more than likely be much more shiny and new looking than stock pistons... and i'd find a different tuner!!!!!!!!!!!!!!!!!!!!!! and putting lower compression pistons in will hurt your power a little

 

what is the compression?
did it get retuned?
and what injectors are in there.

what i would look at is if it wasnt retuned you put lower compression piston's your whp isnt going up.
if you dont have big enough injectors to support more psi.

but if you feel that you got *** raped then take off the pan and windage tray and you'll know for sure.
or do a compression test and if its lower then 210 like 170 in each cylinder then they did there job and just suck at tuning. jk

 

pull a spark plug and look down the hole with a light. if you cant tell if its a stock or forged piston, sell the car and go buy a metro.

 

who tuned it?

get a 3' downpipe and 3" exhaust

do a compression check

drop oil pan to see if it has pistons/rods

 

pull a plug shine a light in and see if there are new pistons in there

 

maybe he didnt go past 11psi because you have a stock map sensor? .. of the shelf weisco's are what? 8.8:1 C/R do a compression test, you should get low numbers across the board if you have 8.8:1 CR VS stock compression.

 

Id say your tuner/mechanic knows what is going on it you you that doenst know what you bought and why.

If you thought you had to buy pistons and rods and you would automatically make more power you obviously dont know much.

They simply make it safer for you to turn up your whole set up and be Safer.. there is never a garuntee but Safer you are..

 

I swear people need to do more research before boosting their car. "Why isn't my turbo car putting out way more power now that i put low compression pistons in it"? lol

 

and before you start pushing more boost, ditch the stock map sensor it appears your still running... might be why the tuner does not wanna push more than 11psi.

as for if it really has piston/ rods or not... pull the head or pan and check.

as someone else asked... give us some more details on your setup. what kind of fuel setup and management you have?

fyi just because you seen someone do some numbers on honda-tech does not mean its the norm or automatically gospel... all dyno's are not equall, for lack of a better way to simply put it. also your tuner maybe keeping things conservative, as opposed to someone else on here with a similar setup making better numbers did not.

 

Easy guys, this guy comes from the allmotor world; where if someone makes 201whp on the east coast with setup "A" on dyno "X", VS someone making 203whp on the westcoast with setup "B" on dyno "Y" - setup B becomes the new bandwagon, obviously.
