my rb has no balls.

[PorkChopExpress]

took her out today, it has no power. idles fine 20hg vac. goes smoothly throught the rpms when wot. boost gauge goes right to 8 psi but doesnt feel like it.

its a rb20 btw.

also when bypassing the heater, do you block off the lines? i connected the inlet with the outlet on the block, but its not ideal.

First things first.

Check timing, check plugs, check for boost leaks.

[gomer23]

What fuel pump? stock FPR?

[PorkChopExpress]

i put a new set of plugs in . has the original timing belt and timing.

prayed starter fluid on the piping/intake to see if there are any leaks.

has a walbro 255 with the stock fpr, i heard this MAY be a problem but doesnt seem to be running rich at idle. have a fuel pressure gauge in storage somewhere.

mods are, walbro 255 fmic no exhaust, im workin on fabbin up a downpipe.

check sensor under intake manifold... Knock sensor i believe... If its disconnected then she is pulling timing badly. Do you notice the exhaust sounding louder? More of a throtier tone?

no exhaust, no downpipe thats the problem right there you wont feel boost

[Coolwhip]

I ran a RB20 with the exhaust coming straight out the O2 outlet. That was an experience...

for the neighbors for the 3 weeks I did.

[gomer23]

My car would die when it went into boost, felt like hitting a brick wall with my Walbro 255 and stock FPR, i bought the nismo one and cleared that right up.

[PorkChopExpress]

runs smooth just feels about as fast as a dodge neon.

cant even break the tires loose in first with crappy stock tires.

guess i can put a adjustable fpr on. gonna use a accufab unit . used them before. like em.

also got to dig through boxes to get my timing light out. gotta take so mutch crap off to look at the plugs but will do that to.

anyone know about the heater inlet/outlet on the block? block em or connect em?

[PorkChopExpress]

feeling comfterble with the last run i took her out again today and let it open up alittle more. it shuts down at im guessing 4-5k rpms.(dont have a tach hooked up)

purchased all the parts for the fpr. will update after that.

[Bluefire]

Dump the Rb20 and buy an rb25/26...

Anyways like other people have mentioned before timing, boost leaks, fpr, knock sensors, maf...

As for the water lines you want to loop them, don't block them off.

check for boost leaks...stock boost on a 20 is 10psi.

[PorkChopExpress]

k think i found it. i pieced together my ic and piping cause i had most of it already. used a 90 with a bov on it(not connected to vac) and it was leaking when in boost because of that. dont know why i didnt think of it before.

she pulls like she should now. still a turd but we can fix that 2

like usual thanx for the help guys.
