i would like to see the inside of that Intake manifold you got there.

sloweredcivic

Okay I have read about 100 pages of this thread but its just to massive...

Can you bolt the S/C and manifold up already assembled? I have them together now kinda of trying to mock it up seeing where the stuff on the fire wall needs moved and I think we could bolt it on the head with the 2 already together?

Gold DA9

SOHC or DOHC? Also what chassis?

sloweredcivic

It's a B18c5 in EF, the S/C pulley seems to clear the brake booster also.

Gold DA9

its gonna be a pain in the *** to get to the bolts on the bottom of the intake manifold.

Okay I was just wondering since I don't have a real Eaton gasket and was gonna have to use high temp silicone I just didn't want it to get everywhere...

OK....am I the only one that's confused. I like the craftsmanship of the intake with the dual outlets but what is that going to accomplish? I see a normal throttle body hooked up to the "S" pipe. So air comes through the throttle body as usual, then through the "S" pipe on to the supercharger where its blown into the JR intake manifold...... now are you expecting the air to come out one outlet into an air-air cooler and then back into the other one on its way into the intake runners and engine? I can't see any other way you expect this to work. However, I'm thinking if this is your thought it will not work as the air is going to enter the intake and engine and not want to travel to an air-air cooler.

Is this the way you envision this or am I missing something?

sloweredcivic

I was wondering the same thing...

I thaught it was gonna be a twin charged motor and was missing the turbo part.. but i see no use for those ports unless is plumbed to the t.b then to the turbo but im not sure if hes doing a twin charged setup.

There's likely an internal 'wall' or baffle that "makes" the output from the blower take the route out to the intercooler, and then it comes back in the other opening and into the ports on the manifold/head.

I've seen this sort of setup before, and that's what was done. And the one I saw used an air/water intercooler, mounted where the battery goes in an EG to keep the plumbing short. Otherwise, the plumbing would be miles too long.

Yeah, I thought that as well... however I don't see any welds on the top of the manifold indicating he welded some baffles in. Nor do I see any welds showing he split the intake in half like LHT does. If he was able to completely weld / seal in some baffles without openning this thing up then mad props to him!!

I just did my JSCR on my b18c1 in an 89 HF and it was much much easier to bolt the manifold and the blower to the head then put the head on as a complete package. It really helps to have an exrta hand so u can easily move the head around for mocking purposes.

I CRX I

wait....isnt this the same setup Gold DA9 posted in the previous page that sounded like crap on the you tube video??

Anyone running a stock ITR muffler? I'm thinking about stepping down from a Mugen Twinloop (no i'm not selling it). I want a stock look.

sloweredcivic

That would work but I am not pulling my head off.... Thanks though!

I am still looking for a B series alternator bracket.

Hi all,

This is an amazing thread - thanks for all the helpful info.

I have two 88 CRXs. One I'm building as a fun daily driver, the other as a more serious weekend racer. I picked up a JRSC kit (the ITR one) for the daily driver the other day. I'm a fan of road & rally racing (esp. tarmac rally) so I thought the supercharger would suit me well. Since then I've been doing a lot of research to figure out what else I need to do to the car.

I think I could run it with what I have listed below. The only parts in the list I don't already have are the Chipped ECU, the Hondata IM gasket and the NGK plugs. From what I've read, running 6 psi with this set-up should be OK but I worry about how the stock pistons and rods would hold up to 8-9 psi.

I do have a spare set of forged rods but no pistons to go with them. I figure upgrading the pistons would cost about $800 in parts ($500 for CP pistons, rings & pins; $85 for rod bolts; $65 for bearings; $100 for a head gasket; $30 for the oil gasket). Of course then it becomes tempting to just spend another $900 for the LHT intercooler so I can run 12 psi.

The thing is - that's $1700 I could be putting into the other CRX. Not to mention that it would take longer to finish the daily driver. So I guess my questions are:

Do you see anything wrong with or missing from my build?
Do you think I can run 8 or 9 psi safely on this build without getting forged pistons?

Thanks in advance for your help.

I was refered here by a friend for the welding and fab board, but I stumbled upon this and couldnt believe the amount of activity here compared to some of the suzuki boards i frequent. Great stuff.

anywhoo..here is my work in progress..it isnt a honda or a jrsc setup but shares some similarities none the less..

1.3 suzuki swift with a g13ba 8 valve engine( think samurai 1.3 ) with my own intake an a m90 from a GTP. 75mm vitaras (7.5:1 static-- roughly), gti rods, MLS headgasket, ARP type head hardware,Thouroghly ported head, and mike cove 226* at .050"-.395 lift camshaft. Solid folowers. I am draw through carbed with a boost referanced Holley 350cfm 2bbl. Non intercooled. the intake is a runnerless open plenum with bellmouthed port entry. I am limiting boost to 13 lbs via the bypass valve adj. screw..I am closing to basically half closed with no ill effects. 13 lbs, 15* locked dizzy. Im shooting for 150-180hp..probably on e85. Its boost responce is instant and will most dfinately produce well over 25lbs with the bypass completely closed..check 'er out, and thanks for the great resource!

Cool project.

My one comment is that the m90 is too big for your application. A m45 would likely be perfect, but the m62 would be easy to get. re gtp I think the m90 will result in 10+ less hp due to the extra blower loss from the big blower.

Cool project. Let us know how it goes.

rtsblwn

Been there with a m62, done that. The m90 puts me in a pretty good spot on its map based on the math ive done.. a little to the left on the island, but still plenty efficiant at realistic revs. I dont have to drive the crap out of the blower to get the #'s. I know there is more parasitic loss, but its what i got to work with..testing thus far is very promising..it is very quick especially on top. still have some tuning to work out but i am currently battleing wound MRSA..shitty deal working in health care. thanks!

Mr. Em1

iTrader: (1)

Yeah the m90 looks a bit too big for what you are trying to do the m62 will be more than enough and if you ever plan on putting more power into it later you will have the room you need to do so. but hey nothing wrong with running a huge charger!

Veris

What happened to the m62? From that picture I'd get a bigger air filter...

MRSA is a crappy deal; good luck.

spliftacus

Can I put crower stage 2 cams with super tech springs and retainers on my b16 jrsc setup on 7 psi...?

rtsblwn

That was another build..diffrent motor, different vehichle..it ran great. It was on lpg, throttle reponse, and lowspeed opperation was crutial in a 4x4.

My m90 motor is currently in a 97 swift. It is currently running and awaiting installation of my innovate lc1 and some tuning..
