Whats up guys!
I have a 98 civic hatch. Im thinking of putting in a B18c5 type R.
i wanna know if that motor can be boosted?
I know its high compression but wanted to know.
is there a limit?
i need your guys help!!!!

 

Any motor can be boosted. It's all in the tune.

Higher compression motors make more power under boost, but require a much more conservative tune.

if your talking boost, the gsr (b18c1) will be the best choice. The c5 is more for a all motor setup. Consider that a c5 will run you 4gs roughly, the gsr motor will run you roughly 2-3k. With the extra money left over you can boost the gsr motor and gain more power.

 

oh.
thanks.
if i get a b18c5 can i still build the internals or do i just leave it the way it is?

 

the gsr cams are great for boosting. stock internals would be fine unless you're wanting more.

 

most people that get R's want to go fast stock, if u want a allout turbo motor go gs-r. the motor is cheaper.

 

a r with boost is great, supercharged.

 

so if i buy a b18c5 spec 98+ i just have to leave it how it is??
if i change such Intake Manifold my Hp would increase??

Most aftermarket intake manifolds are actually based off of the ITR intake manifold.

ohh.
but i know it comes with a aftermarket manifold,but if i change it to a skunk2 manifold would the hp increase or stay as it is??

 

if you get the c5 a different intake manifold would practically be a waste of money. if you get the c1 a different manifold would be a good idea.

i just thought that would make it easier for you because i dont understand what you mean by<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by 4BangahEK9 &raquo;</TD></TR><TR><TD CLASS="quote">ohh.

??????????

 

oh okay.
thanks for the tip.
i show just leave it the right?!!!

 

if you get the c5 then yes you should just leave the Intake Manifold alone.

but you're wanting to boost it.

the GSR would be best.(like everyone has said) the cams are good for turbo and it's got a lower compression so it can handle more boost as compared to the c5.

i guess really the question is, how much money do you have and how long after your swap are you going to get boost?

 

Get the GSR if ur gonna boost it, yeah you can boost the ITR but it's not worth it in my opinion.

 

Yep, you have to have a conservative tune with boosting a c5.

I'd rather blow up a $1500 motor than a $3000 motor.


Boost the c1. they can handle 300+ whp on stock internals.

If you do get the c5, the best intake upgrade you can do is individual throttle bodies. It's an n/a motor, there's a reason so few of them are boosted.

 

okkay.
thanks guy for the opinions.

 

is it possible to build up the b18c5?

No.


YES!!! Why wouldn't it be possible? it's not like honda put a lock on the engine so no one could take it apart. There's always parts you can improve upon.

you really dont listen to well lol ok you can build up any motor a b18 c5/c1 are the same block and same crank and same rods only differance in the bottom end is the pistons they both have completely different heads IM and Header but as noted before by everyone else it is a lot cheaper to build a damn gs-r so why are you so head up about a type-r the type r is a good N/A motor but honestly i wouldnt want it for a boost build unless it was to be supercharged and still i wouldnt even do it i honestly think c5's are worthless unless you want a fast stock car its much cheaper to just build a gs-r first off i think the tranny is much better for turbo use and the fact that even if you buy the gs-r or c5 for a good turbo build you or at least i would completely redo everything resleeve all new bottom end about the only good stock item is the crank which can hold 600 hp safely so basically why spend an extra 1k on a c5 when you will be completely redoin the entire motor newho once again sorry everyone for no punctuation or capitolization i seem to be running on and on a lot lately

 

7psi is safe on a stock R with required tuning. In addition, with higher compression, you don't need to boost alot to make alot of power unlike compared to a gsr or some sort.

im hitting 295whp/180tq on hondata s300 on my stock 98spec motor. And I daily this car. Its been half a year and it still runs like a champ. But you also have to be smart on how to drive with boost

it's possible but a huge waste of money in my opinion, go with a turbo gsr!!

 

so did u boost 7psi on a stock r?

A lot of people have boosted type-r's.

Though it's kind of a waste to potentially damage a motor that wasn't designed for being capable of handling boost capabilities.

It's just not worth the trouble when for the same price as an ITR swap, you can turbo a gsr swap.

Yes, but why? It's retarded. You'd be paying extra for internals that you won't be using. Why buy something more expensive when you're just going to replace it? Start with the cheaper engine.
