I am considering doing this swap with the intension of running it for year min then building and boosting it and I had a few questions.

How do these feel power wise in an EK HB?

What possible bolt mods would be usefull for the $ considering it will be built and boosted in 1-2 years?


Thanks

b18b's pull nice in hatch's, but they're really lacking up top. An intake and header would kind of be a waste if your crossing over to the darkside.

chris_si98

it would have decent low end power

if your going to boost.. don't waste your money on bolt-ons. IMO you should just save up and boost your engine properly and tune it properly also.

LS+boost is a good combo. Goodluck

yeah, if you're planning on boosting it... bolt-on are useless because when you turbo it, your cai and header won't have use...

you might instead should work on the brakes and suspension first... get a stage 2 clutch... lighten flywheels.... or find an lsd tranny........ those stuff will come to full use when you have turbo... when you have a fast car, you want it hold to the ground and you want to stop in time too... and you want lsd for good launch... and also, you need a good clutch to hold the power when you shift.... so much to do when you're thinking of turbo... don't waste money on bolt-ons...

Keep it stock, do suspension and brakes like some have suggested. Get a LSD transmission and it will keep you happy for a while.

Guaranteed. (lack of top end can be disregarded if you do city driving most of the time)

definitely would recomend doing this swap, im putting a B18b1/GSR in my car right now (along with auto to manual conversion). Just leave it stock for now, if you find an intake for cheap throw it on but dont spend anymore than $100 on bolt-ons and just save the money for the turbo setup. I would personally recomend getting a GSR tranny with LSD as it has good gearing for acceleration aswell as you can drive on the highway without having to sit at 5000rpm at 120.

Cool thanks for the input I have all the parts to do a 4 wheel disc setup on the car and plan on more suspension upgrades although I have some done.
When it comes to bolt ons I can get a short ram intake for nothing and a used header for 100-150 so both of those will be going on. The big question would be about fuel pressure regulator, cams or intake manifold those type things some of which I think will be reusable once I boost it?

i would suggest getting a better intake manifold and throttle body, but the only thing is that the IM that would be your best bet to use on a boosted car is no good for N/A. I am talking about the edelbrock victor X intake manifold. Its designed for forced induction and/or 7,000-10,000rpms.
An adjustable FPR is a waste IMO. You could grab some cams, but don't get anything more than a stage 1. If you really want cams i would wait until its boosted and grab some turbo cams. They're specifically designed for boosted applications and have very little to no overlap, which is desireable on a boosted engine.

Capo

Get your suspension and braking up to par before you get into the turbo stuff because if your car is all over the place on the road and cant stop then your just gonna get into trouble. FPR is pretty much useless unless you have undersized injectors for your application. What kinda power goals do you have for the engine when you turbo it? If its under 300whp then you really dont need to invest in an intake manifold or cams as the stock pieces will work fine for low boost applications.

PurpleCX

HP goals when I boost it will be 250-300HP
As to the FPR I have heard from numerous people that it is a worth while mod of course these same people do not have one on their cars, so...

chris_si98

if your plans are that high.. look into some good pistons/rods. Arias or vitara are a good choice on a budget for d-series engines.. i'm not quite sure if they will fit b-series though. I remember hearing there aren't a wide selection of l/c pistons in canada (may not be true) Also get some arp rod bolts, the list can go on and on.. it just depends how much money you are willing to spend on it.

Do some research.. all your question can be answered with a little research.

edit: after searching a little bit.. i don't believe vitara pistons will fit b-series. sorry for the misleading info

PurpleCX

The 250-300HP numbers are for when I boost it and that will be in 1-2 years and I will not even start the research on that untill I am at the point of having the money to start getting the parts I need. For now I am just looking for some info on the base B18b bolt ons that will not be a waste of $ and time.

the vitara pistons cannot be used on b-series engine because b-series' have a 81mm bore.

Here comes a novel - LOL

Good to see someone going nonvtec. As far as going turbo great, but I've seen it enough that projects get doubled in time if not more so I suggest...

Good idea with the intake and header, always something that should be done, especially because you can get them for CHEAP. The first thing you should purchase is cams, such as the Crowers, 403's are great and for more aggressive go with the 404's. They might not he best choice but still work well when boosting but for the time beig they give you a great power gain. Best thing is nonvtec cams are cheaper.

Also opening up the motor will do good so a larger throttle body or just machined will help, and intake amifold will help, but no huge gains.

I would rather change over my pistons instead of anything else. Swap in a set of PR3's and up your compression for the time being until you go turbo. Put up a WTB and you can pick them up for cheap enough to make it worth while.

So swap over cams and pistons. Do an I/H/E. Get it tuned and you can make some decent power, and its useable.The next thing is you need to upgrade your tranny. Look for a GSR or B16 something with a better gear ratio, and if possible something with LSD. The LS tranny is just a dog and will hold you back the most.

newman

Oh and 250+ hp, although you can reach it it's not something that is that easy to hit, so do your research and spend you money wisely.

imported_t_dot_SiR

just work on the suspension and brakes first...
also get good bushings allaround the whole car.....
gsr-lsd tranny
lightweight rims with good tires
lighten flywheel
those will keep you happy on the stock b18b

Capo

if your goals are only 250-300 and the engine you have is in good condition then theres no need to open it up and change the pistons or rods. If you want get some ARP rod bolts, main studs and head studs and that is some cheap insurance. As long as you do the proper research and get it tuned by a good tuner your power goals are very achievable.

For now just do Intake and header, exhaust if you find something cheap but otherwise its not worth it because you will most likely swap it out when going turbo.

b18 in an ek is mid to high 8 second car... if you get the jdm one, then youll probably break into the 6's.

MUHAHAHAHAHAHAHAHAHAHAH

To make 250+hp on a stock motor without opening it up will not be reliable. Even when opening it up 250hp is hard to reach let alone 300. To reach the higher numbers you have to build the motor, end of story.

Like I said do cams, pistons, I/H/E and TUNING.

You will have a lot of power and torque, for a small investment. You can be in the range of 170/140. But the mod that will notice you the most difference would be the tranny.
