what up guys i have a 88 crx si w/ a jdm d15b that motors halls ass,how can i increase the d15 hp and tourque

what do you guys recommend :mrgreen:

 

[jmart]

forced induction

n2o

head porting + big cam

NA = Expensive, probably not the best route

Force Induction (turbo/super charger) = Probably your best bet for power increase. Expensive if you want clean good parts, cheap if you want a backyard 200whp engine.

NO2 = Not worth it, bottle fills get expensive. Not legal in most states nor Canada to have it hooked up.

turbo does sound fun, i would have to get the block sleeeved and woeked on before i can turbo it or what can be the safe rage of turbo without having to go threw all of the block work thats if there is any.

Umm I don't know what you heard but honda blocks are tough. You just don't wanna be pushing too much on it. 10PSI is a safe number to peak the turbo on. But I'd look into some rod bolts and headstuds at that point.

I'd lean even more towards like 6-8 PSI honestly. You can run 10 PSI from what I've seen and have a healthy motor stay healthy for sometime, but natural wear and tear is going to reduce the life of the motor the more the boost applied.

Lots of reading will help learn what will and won't work better with a turbo setup. I agree, NA is quite costly and I wouldn't choose that route for the most power, although I would for the most reliability. N2O is N2O, I don't like blowing up engines.

so a good safe number for a turbo would be in the 6 to 8 psi that make the motor life alot more stable does anyone know of good turbos that would give me that number 6 to 8 psi ( sorry dont know much about turbos ) they many vary from the most expensive to the cheappies let me know guys

PS i whant this cuz i what to buy a eg hatch and make it a daily driver with the jdm d15b and for my rex i have a completly different route for it like OoOoOoh just lest say LS-VTEC all with type R internals :twisted: cant wait to stsart putting it together

Most internal wastegates are set at 7lbs. Makes for easier setup. I got a Garrett for my setup, but still not assembled in my car. I need TIME!

When I was looking to turbo my SOHC I was told by alot of people to settle for a 14B turbo. If my memory serves me right it's the stock turbo from an SR20DET.

A 14B is a stock turbo from the 4G63 DSMs.

Jeff is correct..
The TD05h or commonly called "14b" is from the 1st gen eclipse.
Hope that helps..

 

[racejdm]

so basically that turbo will give me good performance ( dont know nothing about turbo sorry ) will all of the turbo components fit the d15b without any problems and just like i said it will give it good performance.

 

[ollie]

Yeah if its set up right.I know that my turbo setup on my mini-me makes me happy in the pants at full boost!
But in all seriousness DO READ up on boost and turbo how to's.
I know I learned a lot from this site.----http://www.homemadeturbo.com-----

A properly thought out turbo setup doesn't have to be crappy or unreliable,or expensive for that matter!
I can share my boost setup w/you if you need be.Just PM me.

 

[racejdm]

would the turbo that you guys recommended fit a b18a1 cuz im planning to perhaps turbo that engine as well
let me know if you guys think it would be compatable
