I have a 2000 civic with a jdm type r motor. The car is completely stock including the b16 header and exhaust. Its always felt fairly quick but today i brought it to the track. It ran horrendous times and was only trapping at like 87mph. I figure it should be trapping in the low 90's yes?

Do you think the stock manifold/exhaust could really choke the car that bad or perhaps theres some kind of fuel problem? The compression on the motor is good.

 

whats your 60 ft and 1/8th

 

a 2000 hatch or coupe? the type-r engine was not designed just for drag racing. its a great engine by all means. but that sounds about right as far as 1/4 mile trap speed. what were you expecting?

 

not true he should be trapping higher than 87 mph. I did higher than that with my B20 nonvtec back in the dayz. 14.9 at 92 mph on falken ziex. When I slapped on the Vtec head i trapped at 101 mph with a 13.7 so he sould at least be in the 90s Im guessing it's probably the stock exhaust or the driver error. When you change your exhaust to a 2.5 or better if your motor i healthy and you have the right map on your ECU you should be trapping at atleast 95 with at least a 14.7 or better

 

not true?? i wasnt stating facts buddy. how the hell can you say what his trap speed is suppose to be when you dont even know how heavy his car is? so please dont quote me. just like you said it could be the driver. anyways, we dont know what model civic he has nor do we know if he has a b16 type-r or a b18 type r(but since he said b16 header im guessing his car is a SI). we dont know if hes using a type-r tranny that has lsd. you did higher than he did cuz thats you. you might have a lighter car than him(u didnt say if you had exhaust) plus a b20 has more torque than any b-series type-r engine so you would more than likely have a better 60'. no his stock exhaust is not helping, either is the b16 header..i agree with you on that. but why do you think he should have a better trap speed? you cant compare what you did to what he accoplished. based on what he told us he trap seems to be just fine. now if he said 80 mph that would be another story

 

this will give you an idea UNforgivABLE... this is the factor type-r specs.

Yes, the stock exhaust manifold is choking the motor. Yes, you should have the car tuned.

 

Are we talking Integra motor or Civic motor? I'll assume the CTR engine if you say you have a B16 header on it. Is this swapped with LSD trans or does it have just a B16, GSR, or LS trans in it?

If it's the CTR swap, your MPH is probably about correct. If it's the ITR swap, you're underperforming unless your car is carrying a bunch more weight than normal.

 

o god... 15.9 ... ive got a b16a in my 99 ex and it has a stock muffler on the back n went 15.2

 

so what was your actutal quarter mile time?

 

i put that up there as a ball park figure, a reference for him. he shouldnt feel so bad for his speed he was trapping. so your b16Ex has stock clutch and flywheel? it must of took a couple passes to get that 15.2... not bad though

 

first was 15.39 then 4th 15.2 n i beat the **** of of it full throttle **** n stuff

 

a b20 dosnt have more torque that a type r first of all. and second of all the 87 is in fact slow as **** for a type r swap it should be in the mid to upper 90s. and dude for real its a forum quoting is what this is all about. simply to clear up confusion so chill.

 

what type-r engine??? we dont know which one he has, theres like 7 different ones. the only type r engine that has more torque than a b20 is a jdm b18c from the 98 integra type-r(rated at 138ft/lb).he may not have that engine or the s80 tranny(with the 4.785 final drive) which gives it that amount of torque. all other type-r engines have less torque. not sure if you read smart guy but he has stock b16 header and exhaust which is hurting his car. so NO his type-r engine doesnt have as much torque as a b20 until he can get a hold of a type-r exhaust and header or greater. once again his trap speed is very close to were it should be. after all none of us know how great his driving skill is so you have to take that into account. a simple thing like the distributor not being correctly positioned can hinder his over all performance(this happens a lot). there are many things that could keep his engine from performing to factory specs. you cant just simply say his trap should be in the mid to upper 90s. every engine is different and so is the driver. thanks but no thanks for your input supra-n-civic

 

sorry i shouldve been more clear on some things

its a 99 civic si with a 2000 JDM B18C-R ITR motor coupled to the stock b16 transmission, with the b16 header and exhaust(which fits fine).

im not a great driver but not incompetent either, was cutting 2.3 60fts on real shitty street tires. Nevertheless i really feel the car underperformed.

 

ok, thanks for clearing things up. two questions. have you checked your timing lately? what kind of clutch/pressure plate are you using?

 

Better yet what ecu are you running? If your running the si ecu there is part of your answer.

 

Tune up also

 

its the type r clutch and pp, type R ecu, timing might be a good place to start although we checked it when we first did the swap with a timing light and it was ok, it has the b16 distributor because the one that came with the motor was shot


thanks for the replies sorry i was light on all the info

 

What were recent compression numbers?
Check your spark plugs?
Have you looked inside your cap and rotor?
Check your timing?
Clogged cat?
Is vtec working? Hear it engaging? Have enough oil?
Are you running in safe mode?

 

yea that sounds a little ruff, i know i have a different chassis, but i have a 95 gsr with the jdm b18c (SIR) motor, and back when i had just header/intake/exhuast i was trapping 95 mph with gsr tranny.

 

 

^^ i could be misinformed, but im pretty sure the USDM itr header is nearly identical in design to the usdm b16 header that he is using...my point being it doesnt seem to rob too much power from the b18c5...... its tough to believe that the exhaust system would rob 6+mph off the 1/4...only one way to find though i guess...

 

I have run a few 15.20's with my last EM1. Just had an AEM CAI on it.It trapped at 88.5 mph. It's your combo of parts that choke the motor,and lack of tune.

 

are you sure that your vtec is working lol.
