Boost the B18C5? or Turbo D?

[VTECDreaMs]

Well I'm back to deciding what i want to do

I could buy my dads 98' Type R off him(57k on the motor) but I'm not sure if i want too. I know i want to boost whatever i get, and i've searched around the the B18C5 doesnt seem to be a popular motor to boost? Maybe im just looking the wrong places, someone show me otherwise.

My friend has an Evo 8 and i fell in love with boost after driving that. Call me insane for comparing the 2

My other thought/choice would be getting a D Series motor and boosting that. I dont know a TON about boosting cars, but i've been doing some reading and i dont think i'd be using a kit. Anyone with knowledge about either of the 2/experiences... please chime in and give me your opinions. Thanks

well if the price is right buy the type-r. u can boost it but just like any other high compresion motor you have to take the proper precautions. Think about what horsepower number you're shooting for. i think for every psi you throw at a motor you get roughly 10 ponies. on stock internals you probly wanna play safe and stick around 5-6 psi. if you are wanting to throw double didget psi at it you'll need to rebuild the bottom end. but i'm not an expert by anymeans. but they always say being smart doesn't mean how much you know, but knowing where to find the answers. so get on the internet, do some homework.

good luck

He's right. I would definitely shoot for that type r and boost that. If you plan to boost the s**t out of it, you will indeed have to rebuild the bottom end. Type-R is a higher compression motor than most, and high compression and turbo do not go hand in hand. You need a lower compression motor if you want to shoot for double digit psi: that means you'll have to replace the pistons, piston rings, rods, and get turbo cams along with valve springs and retainers. Otherwise, you can leave stock internals and boost 7psi at most. Hope that helps.

I was kind of in the same situation as you. I had to choose either a turbo d or a n/a b-series. I didn't know jack about turbo's and I still don't know a whole lot but I'm learning. Well I chose the turbo d16 and I fell in luv.
It's tuned properly and when I need that umph I just hit the trottle. I went the ghetto way and built my own kit off a mitsu. For all the bad s**t I've heard about cheap turbo kits (ss autochrome) I'm glad I went with the custom dsm kit.

listen to that whistle (stock dsm bov) no traction in 2nd

If your gettin a good enough deal on the type r go with that just keep in mind its going to be very expensive...but u can get great hp numbers.

If you go with the d there's a little less hp but they can be fully built and boosted for realitively cheap....check out turbod16.com.....lots of good info

If you boost the type r you will have to swap pistons, and ill kinds of other s**t, your best off to by a SOHC Hatch and turbo that, but unless you got a bunch of money it still wont be an EVO

I'm guessing your dad would give you a good price on the type R? if so DEFINATELY go B18c5

However you shouln't be shooting for a certain psi, shoot for a certain power range you want to be in. I think you should buy the B18c5, and before throwing it in strip it and put in some lower comp pistons and forged internals. You sholdn't need valve springs or have to upgrade the powertrain to safely push boost. The B18s have the best flowing heads for boost, the difference between a D16 and B18C5 pushing the same amount of boost is completely NIGHT and DAY. As long as you have a good tune on the engine you sholdn't have to worry about reliability, and if you have a choice of turboing a B18c5 I would go that route, it is like the holy grail to all civic enthusiasts.

go with the type r...u'll have fun driving the car just the way it is..
u can boost any motor ofcourse but u'll be taking the type r out of the type r...

I wouldn' mind taking the "R" out of a motor for another 150 hp

 

[soldiaboy]

damn what kinda dads drives a type R. heres a crazy idea, sell the c5 motor, with that money you can get a ls on boost ??

 

[rickles8099]

boost the d. parts are cheaper, more room for turbo setup, and if you blow a d, who cares cause its cheap and you can get another one. plus the money you save on for all the things you need for the b plus the b motor, you can spend on things like pistons and rods

Haha, Thats what a lot of people said. Hes' 54 and rockin the Type R. Pretty wild. He loves to AutoX in it, and has a lot of suspension stuff done to it. Everything is so responsive.

Anyways, He said 7500 for the Type R. Im leaning towards that heavily. I've talked to a few guys with boosted ITR's over on Club Integra, and they're pushin big #'s(417whp, idk if you guys consider that BIG, but i do, I'm 17 and ballin on a budget ) I'm working 2 jobs so i can get a nice car and tune it, make it a real street warrior. Around here there isnt much of that. I got my friends Evo, an STi, and a bunch of hicks with those "rawkin V8's man" Who think they own the streets. I want to show em differently.

Thanks for all your opinions and help. I havent COMPLETELY decided, but the Type R is sounding pretty good right now. I'm going to go check out TurboD16.com and see some of the stuff they have going on over there. Thanks again for alll of your help.

hmm... IMO if i had a B18C5 I would jus keep it N/A, and turn it into a high revving all motor madness! Turbo D's though can be pretty quick and nice for street use, and track days. I'd go for the D, but a USDM Type R for 7500... damn, thats pretty tempting and very nice.

^^^ knows what he's talking about.

You will incounter problems with a turbo eventually. Whether it be vaccuum/boost issues or thrown rods (through your oil pan or hood), your going to eventually have something crap on you.

Not to mention, high compression is NOT ideal for daily driven boost. Maybe if it was a track car, and you plan on runnin C15...

For future reference:
HP per PSI depends on how much CFM the turbo flows. 1.45 CFM = 1 hp. Your compression (as well as redline and volume) determines how much base CFM your motor will flow. Then the turbo takes this CFM, spools, and pushes more CFM back through the motor.

Anyways, go with rickles and the couple other ppl who said turbo D. Cheaper and plenty of potential. Also... you WILL have issues with traction with high HP.. and braking issues... which all cost money.

thats very steap. I can get a b18c bare block for 300... built head for another 1200... b16 tranny for 800.. quaife for 800... forged internals for 800... and it would beat the hell outta the b18c5 for 7500

You can boost the Type R. You can run boost on high compression. It wont take as much PSI with the high C/R of the ITR as it would with a 9.0:1 engine. But you will have to use caution when adding boost as detentaion will be your number one issue. You can just get some lower compression pistins and call it a day. It will be just fine.
