just got my motor tuned at rrev in Portland. I only made 308 at the wheels and 219 torque on 15 pounds or so.

when we first dyno'd it made 244 at 8-9 pounds,

I have a nsr-tech ramhorn (made 427wheel at 16psi on my buddys 81mm gsr with a to4e 60 trim)
I am running a 3" down pipe with a straight through resonator th turn down right before the shift linkage. the I.D. of the resonator is about 2.75", but I don't think the exhaust is restricting me though : /

we fixed a coupler on the tune day because of a boost leak, then we still had low power and found the I have the wrong throttle body gasket (old school B16a throttle body with the warm up idle valve) I was using a b16 throttle body gasket which would space out the T.B. so it could leak really bad, we pulled the t.b. off and just used rvt to seal it, me and jeff then pressure tested it and it held to 20+ psi... not sure if there is a prob here

Im also using a ebay turbo, its the ar.70 one on there, .63 hot side. jeff said he didnt think that the turbo was the problem because as soon as we turned the boost up it made more hp...

my boost gauge reads out at about 1 bar. and I only made 308? I dont know if I got greedy or what but I was expecting much more like at least 350 whp.


specs on my build:
b18a1 block
arp head studs and rod bolts
b18a1 h.g.
g.e. ls v kit
hallman MBC
eagle rods
wiseco pistons
all maching work done at automotive machine co. in salem.
motor assembled with all OEM honda bearings and rings
motor was assembled by shannon at pac west (local honda perf shop)
stock b16a head with gsr cams
blox intake
stock throttle body
ebay charge pipes ic and bov
ebay t3 60-1 ( pretty big, 4" inlet)

and for the record I originally bought a to4e 60 trim but the guy never shipped it after 2 months and I was in a pinch for a turbo, I had to get my car drivable again.

3" semi open down pipe


we even had people standing on the car to make sure it wasn't spinning...

Im really bummed, I wanted alot more power then that

I'v also noticed poor fuel economy, like about 23-25 with a small amount of getting on it and alot of hwy cruising...

Im thinking it could be the throttle body, not really even sure what t.b. gasket i need though, jeff said get one from an old integra..

any help will be greatly appreciated.

take the air filter off maybe a little diff and stock rings on aftermarket pistons ??? thats not good you need wiesco piston rings have you comperion tested it and leak down tested it yet??

stockb18c

have you done a compression test..and leak down test there is a start...

sanman000719

is this on 91 octane??????

sanman000719

can you post the graph?

iheartteal

stock inj?

sanman000719

yeah or fuel pump issue i was having the same issue for a while and could have changed part for part to get it right or just do a big fuel system so I went a1000 complete system. i HAVE THE T3/66 now at 17psi its make 404/261 on 91 alot better than before. Thats on 1000cc rc's. I am learning it all from step 1 and its costly lol

graph?

turbociv910

ebay turbos arnt the best design, 60-1 isnt big, your power is where it should be with a ebay turbo.

compression test it

K7-1Ktrevor

I will try to get jeff to email me a graph.

it has plenty of fuel, rc 750cc injectors/ walbro 255lph. tuned with wb o2 at mid 11's at wot with 19 degrees of timing.


haven't compression tested it at all yet, the motor doesn't smoke at all and everything is brand new so I figured it was good : /

tried it without the filter and it was a 1 hp gain. I drive on a gravel road for a short distance so I don't want to run it open


the weird thing is the car feels much stronger (previously coming from a b16turbo) my last motor put down around 280 and didnt spin what so ever, this motor spins my drag radials in 3rd. prob due to the torque that I have now though.

connor53

Is this on the same dyno as said friend? quote="I have a nsr-tech ramhorn (made 427wheel at 16psi on my buddys 81mm gsr with a to4e 60 trim"
How was the car strapped down on the dyno? I don't think I've ever seen wheel spin on a dyno on a honda making less then 475hp lol. Kinda fishy.

tegman23

Sounds like that would be your problem to me...Ebay turbos may get the job done but they dont flow any where close to a garrett/turbonetics/ext...

PS: I made 400whp on a stock ls TB so i dont think thats holding you back..16-17psi t3/t4 turbonetics

CRXdan

the size of the inlet doesnt mean nothing to the size of the turbo.
This one seems kind of obvious, I think the power is actually quite impressive given the turbo used.
Strap a larger turbo (or even more efficient turbo) on it and call it a day.

What I dont understand with these builds is that someone will invest all this money into every damn part but use the crappiest turbo they can find.

is this the turbo u used?

K7-1Ktrevor

same dyno, he upgraded to a top mount and made 470.
we didnt think it was spinning but wanted to rule out any possibilitys.

K7-1Ktrevor

yesssiiirrrr that'd be it.
if you read in my post I did by a to4e 60 trim,.... the seller just never followed through on his part of the deal. I really thought it would be more capable. : / o well lesson learned. it makes very smooth power which is what I was after being its mainly a street car. Iv exhausted all my funds on this damn build so Ill be ebay'n it up for a month or two till I can swoop up a nice garrett or BW.

Teglove2

Damn eBay! Sell that turbo for a hundred bucks..u can pick up a garret 60 trim for like 550 bucks brand new if you got a hook up. IMO thats hella cheap. Good luck man.

ATYPR

did you guys try removing the filter???

Scheizty

what vacuum readings are you getting while cuising? If it is 15~20 inHg you should be okay for leaks.

K7-1Ktrevor

tried it without the filter and it was a 1 hp gain. I drive on a gravel road for a short distance so I don't want to run it open


vac is about 15 while cruising. car idles nicely, but the boost gauge isnt very steady in full boost... it flickers really fast from about 13-15lbs....
my sohc on 14.7 held dead steady so that why I think there might be a leak.

I can't beleive all the traction I lost from gaining 20hp :/ kinda bummed about that, I want it to be really fast on the street from a dig.
Im trying to do everything I can to help traction, new alignment, raised the suspension up about 1.5" next Im gonna try doing a burn out in vht befor running... any other suggestions, car is a 94 ex that scales at 2250 with out me.
should I buy some stiffer rear springs. Im running ebay coilovers with kyb AGX's the car rides really smooth for how dumped it was.... I have no wheel hop but Iv been thinking about traction bars, just dont know if they will help me out.

any suggestions?

I want the best mild hp street setup I can get with out having to run slicks.

hyn_boi808

the horsepower is alittle low check compression, then uncap it from the down pipe it should be makin 370 in that range..... my bros ek with ls/vtec piston and rods with complete ebay set up with t70 turbo made 418 on 17 psi

HiProfile

If you disable some of the coils, ie clamp them together (or apart), that artificially raises the spring rate because each coil moves more to move the car less. I think eibach has poly ring things that do the same deal.

I would suggest you just run less boost. If you used s300/neptune/ectune, you'd have the option to run an EBC and use different boost per gear.

K7-1Ktrevor

thats a great idea on the coils and I think It can be done cheaply. I know autozone has the coil spacers but I don't know how tight they hold in there.. with the coilovers I have now I cant raise the car high enough to run slicks.

as for running lower boost. I really don't want to, my friend has a turbo xs dual stage boost controller that he will loan me, but I don't know about it... have people used them with success?

91redteg

no denying they arent the best design but my stock block ls with a crower built head made 312 and 245 on 14.5lbs using an ebay turbo... granted the rest of the setup wasnt ebay stuff but there has to be soemthign going on with his setup other than the turbo. because an lsv should be making way more power than that on 15lbs. i would say look at yur tuner. but rrev has a good reputation so i dunno...... maybe dyno is off a little bit... you shouldnt be having traction issues with only 219ftlbs except in first and second.... which is just typical for fwd.. you cant really expect more than that on the street... but if yur losing traction in third you either have shitty tires/not enough rubber on the ground... or it could be making more power than it is

K7-1Ktrevor

jeffs a good tuner, he made 464 whp on my buddys integra on pump @ 19psi.

I have no doubt its not the tuner.

I had my car up on the lift today, and the inside of my drag radials are DUNZO!.
damnit, I gotta figure out what to do now : /

What kind of dyno ? Sure its not reading 20% lower then a dyno jet thats what happens here in nashville
