After considering selling my hatch now and getting an R33 Gtst type M, i've decided to instead wait 6-12 months 'till I can afford a GTR 32 ot 33, so basically im keeping the hatch for 12 months and in the meantime im gonna make this hatchie go real good...I wont even botha with an engine swap 'cose im not gonna keep it for longer than 12 months. Ok, so this the deal...D15B with around 133hp stock and I want increase this by at least 30-40hp without going turbo, I honestly dont know how challenging this is but I do hope that some of you guys here can help me by letting me know wot mods (other than I/H/E) will help me reach this much hp ! I already have quite a few ideas but my dream was a b18c in there rather than the d15b...so single cam experts please help
PS: i will keep updating this thread to let evryone know how my project's is going yeah??

sparq

simple, shoot it with a 75 shot, done - why would you spend money on mods and crap when you know you are just dumping the car? Save your money

LHC

sounds tempting but im gonna drive this car everyday for the next twelve months+ im gonna sell it and I dont want the motor to be fried by that time...NOS= mainly for that reason...

sparq

You will only fry your motor if you act like a jackass with it. Just because you have NOS doesnt mean you have to flip it on at every stop light - not to mention its illegal to use on the street anyways. Like I said, your ditching the car in a year, save your money.

LHC

thanks IMO...however, money is not an issue here, an extra 30-40 hp out of the d15b is the issue; can you tell me from your own experience wot other mods apart from I/H/E can help me to reach my goal? (take away NOS and turbo! )

South Bay Surfer

i got the same motor in my car and am wondering the same thing, i wanna stay away from Nos cuz i want to go all motor and i already have i,h,e.

LHC

have you dynoed your car to see wot you're getting with your current setup?

LHC

I think theres someone here called singlecanscreamer or sumting like that...i might go looking for him so I can IM him about this better...I.L.L. i'll IM if I find out any good info yeah?

South Bay Surfer

not yet, i heard that this setup is fast enough to keep up with stock b16's. have u had any interesting encounters?

Slopoke

Well I/H/E will get you maybe 15hp, maybe

For 30-40hp your looking at probably some serious head work and tuning. $$$$$$
Have fun.

itsmike

Just start with I/H/E, since youre not going to keep it long anyways theres no real point in doing too much to the car.

Slopoke

Well I/H/E can run you as much as $1000.
Why waist the money if you are planning to get rid of it?

I'd have to agree with sparq.
If your looking for some cheap fun, throw some nitrous on it.
A dry nitrous kit jetted for 30 or 40hp with a little 5lb bottle would be easy to install(and uninstall when you sell the car) and would be pretty easy to hide.

I didnt think the d15b had 133 hp? Could be wrong though.

LHC

well according to Temple of VTEC Asia the JDM d15B that comes in the civic VTI or EG4 produces 130 ps...im not sure how to convert this to hp but im sure that its just bit less or a bit more

sparq

The NON USDM spec D15B puts out 103hp @ 6400 rpm / 128hp @ 7000 rpm for stage 3

Want 40hp? new AEM V2 intake, 4-2-1 header, no cat, larger exhaust w/ high flow muffler, JG cam & cam gear, 3 angle valve job, a hell of a good port and polish and bump compression up.

LHC

according to the information i've gathered i've got the D15B in the EG4 which makes 130ps...that makes it about 127hp...i got this inofrmation from an article from the the temple vtec asia

I am running a stock CX motor with a Z6 head and intake mani....I must say it works really very well. The CX pistons are flat top with no dish, so the compression is over 10:1. The thing is really nice. Totally livable as a daily driver and in my CX it will hang with 99-00 Si ****. Totally cheap too....

Just do IHE, you will be fine.

Well either you already have I/H/E or you aren't willing to put them on. And if you aren't willing to put them on then you probably aren't willing to crack the motor open. And if you don't want to use nitrous then I don't know how you are going to get any more power out of your motor...hopes and dreams?!

I suggest you don't do anything aside from I/H/E (if you don't already have those), unless you are planning on keeping the hatch alongside your Skyline. If you are selling it, then I don't think it would be fair to the next buyer to rag the crap out before you sell it. Unless the buyer will be swapping or rebuilding it!

But, if you are keeping the hatch and you don't feel like putting much money or work into it, then spray it!

You can do plenty if you don't want nitrous. Check out the d series mb here:

Bisi Ezerioha is a member. There are also a ton of others that know their sohc's. Besides i/h/e, look into Crower stage 2 cam and upgrade the valve train while you're at it. This will make more power than the zex 59300 cam which will also work. You can also find p&p heads for relatively cheap, or you could have the work done. You can also run a1 piston's (p29 I believe), but be careful - they will yield high compression. Don't quote me, because I don't know the specifics on all this, but they are some ideas that you can begin researching. I'm going to be running a full gude z6 head package (cam, p&p, bored tb, ported im, ecu, etc) on a y8 block with i/e and the Bisimoto header (designed by.....Bisi). I'm looking for at least 160-170 flywheel horse. Hope this helps.

I think you are dreaming about your base HP figures. I think 100hp is more like it. You might be able to get another 20 with IHE but thats kinda a stretch too. The only real way to make power is to crack the engine open and build it or try this, drop in a SOHC VTEC motor. You can get one of these for around $500 sometimes cheaper. Here is an easy 20-40hp for the cost of an exhaust. From here drop in a cam, polish the heads, do your IHE and maybe even build the block with I think its 88-90 Integ pistons. Of course now you need more fuel (VAFC) and dyno time to tune it. Basically that 30-40hp is gonna cost you. If you are getting a skyline in a year, just wait and dream cause building that motor is either gonna take time and money or if you don't spin your own wrenches lots of money... just my .02

h45454

No, he is right about his hp figures. The JDM d15b is sohc vtec. I believe it's basically a vx block with a z6 head. These could also be had with factory lsd. It's a sweet little motor. The USDM d15b7 is probably what you're thinking of - non-vtec and 102 hp.

If you are waiting 12 months so you can afford a GTR, that must mean you dont have the money now. So if you keep the hatch and continue to spend money on it, what makes you think you will have any more money in 12 months than you do now. You will have a little more money and a faster car. Leave the car like it is, suck it up and wait for the GTR.

LHC

Thanks for all the responses...I appreciate all the opinions, however, I would like members to understand that convincing me not to go ahead with this project is futile, this is something that i really want to do and have the funds available right now to do it...about the GTR: its not about having the money now, is got to do with insurance cost and credit rating , 'nough 'bout this shiet...now some more questions
1. so 88-90 teg pistons is the go for the d15b head...does anyone with/without this setup know wot CR is and how realiable it is
2. would i be able to get the IM out of a JDM y8? is there such a things as a JDM d16y8?

9200RPM

the doner motor out of my coup (D16z6) is in a 92 hatch...The hatch runs consistant 8.90's in the 8th mile with drag radials, ZEX stage 1 cam, 6 puck clutch, and a ZEX kit spraying a 65 shot...when i had this motor i drove it hard for 100,000 miles and he drives it hard and goes to the track a lot...nothing else has been done to this motor...the head hasent ever been pulled and it runs great...All he does it richen up with air fuel ratio, and back down his ignition timing 2 degrees, so there is an idea for you.....

9200RPM

Also he plans to do a ZEX stage 2 cam, springs, retainers, and bump it up to a 75 shot......N2o isnt bad as long as you use it right...do dont listen to the 10% of people that use it and say its bad...listen to the 90% that have benefited from it...good luck
