d16z6 177,000 miles
jg performer mani
3 inch downpipe
top mount mani
t04 .60 aireasearch turbo, tuner said it was a slow spollin turbo spools about 3700-4000
hondata s200
2.5 exhaust
440 rcs
arp head sutds
new head gasket

ok heres the number 120whp 119trq
compression 145 to 150 on all cyl are these normal numbers???

the fuel pump starts to give out at high rpms and it needs a stock fuel pressure regulator

the fuel problems are the reason he did not tune it any higher

but my question is?? Is the other reason the numbers could be or are low because the compression

Would a smaller turbo help out any???

should i spring for pistons and rods???

i am just looking to get in the 12s id be happy with anything about 230whp???

i am stuck guys help me out

thanks

hope i didnt forget anything thanks

 

22 veiws but no anwsers i must be in a pickle

BUMP

 

pistons, rods and a medium-sized T3/T4.

 

your comp is low.. how much boost were you running? who did the tuning?


that turbo is way big for that engine..

the most boost i ever run is 9lbs

so you think get a rebuild?? The numbers are close together i thought consistency is key???

RS Motors did the tuning very nice people

thanks guys for the replys

 

were yoir compression tests run on a warm motor?
when you say 120hp, was that on 9psi, cause there is something wrong?
when you say tune, with waht exactly?

your motor reads low, or the test was not performed right. My z6 has 225XXX and at 160000 it pulled 185 across the board. I milled the head and have a zex cam and 220 across all cylinders. You may need a rebuild, good luck.

 

I would recommend ditching the turbo you have (sell it) and going with a 60 trim t3... that will get you 230 whp no problem..

that turbo is quite large and is no doubt your problem.

What boost was this at?

Also get an aftermarket fuel pump

yeah the motor was warm

it was tuned at 6lbs at 120 to the wheels

tuned on hondata

is anyone running a stock fuel pump at 200 to 250 whp?????

thanks guys

 

any more opinions???

 

sounds like something is wrong with your motor or setup. When you did the compression test was the throttle held wide open?

 

i will do the test one more time on a cold motor and throttle held wide open and with all the plugs out and see what happens before i take it in for new pistons and rods and turbo and turbo manifold

thanks guys

 

your compression is a bit low, but i don't think i'd worry about it too much personally. i'd recommend you get a t3 super 60. i have no idea why you have a t4 turbo. unless you meant to say td04? also get a walbro fuel pump and b&m fpr at least.

what do you think happens when you have more air going in at a faster rate and you don't have enough fuel to compensate for it? you better take care of that fuel pump problem.

so you dont think pistons and rods are neccessary right now??? is a t04 .60 turbo its a big turbo now for sale with a custom top mount

i am getting a fuel pump and already have a FPR but i hear stock FPR is better??

i am for sure getting a smaller turbo and new manifold

thanks for the info guys the more comments and help the better it will be

no it has to be a warm motor.

ok it was originally

 

Your numbers may not be low. The same engine compression tested in a different locations may yeild different numbers. There are all sorts of variables that can effect a compresion test. Such as how many times start cycles you are running. My best suggestion would be to say bump compression testing and have it a Leak Down test run. Are you getting alot of blow by?
