New Carbs

[imtb]

Check out my new carbs. Just got them and ready to try out when I get the air filters.

Slides, right? ...and get a PCV valve on there.

[zerow]

What are they? They look real nice!

[imtb]

Mikuni HSR carbs. made for Harley D. but Vintage Performance mods them for cars. I had them idling at 800rpms in no time and they are super responsive.

I've been wanting to do that exact setup for a while, supposed to be head and shoulders above even sidedraft webers. Keep us posted when you get them all tuned up :)

 

PS are they 42s or 45s?

[imtb]

They are 45's I went back and forth between the 42's and 45's I thought the 42's would be to small and when I got the 45's in they seemed big. I fired them up yesterday and had it idleing at 800rpms in no time and it is super responsive the acletetor pump sprays the fuel straight into the head. I had dual dual 40DCOE and they just seemed like to much carb for 2.0L These 45's seem just about right.

 

I took a short test drive last night (no air fitlers) should get them tomorrow. The induction sounds is Sweet sounding. I wasnt ever getting on it to much with the rebuilt eng. Tighter sounding than dual DCOE webers.

 

I noticed http://www.piercemanifolds.com/newproducts.htm has them available. The guy in New York mods them for the

for car use.

 

I will post updates later.

I really like those Mike. Do you think you will need a heat shield underneath them or are they far enough away from the exhaust manifold? I really don't like my current Weber downdraft so I may investigate these as an alternative.

[imtb]

I thought you were going with FI on the PC wagon. It would be a big improvemnt over the weber Dgv. So far the carbs have worked great and super easy to adjust.

 

Here is a couple more pics and I am going to post a video soon. The engine really pulls strong with the carbs.

 

[benzo]

that is a sweet setup. sounds like you got it all set up right. seems like dual 44's or 45's work well for LZ2.2's. I myself run dusl SK45's and heard Steve Epperly uses Z Su's for LZ2.2's. seems like a good set up for many dual su intake manifolds. how much did those carbs set you back?

Just call me Brett Favre ... I have been changing my mind on the FI project every hour or so. I have accumulated some of the parts but just can't seem to pull the trigger and commit to it quite yet.

 

I really like this setup though. It looks very simple and clean. Can't wait for the video.

[fisch]

Bitchin setup man! Can't wait for the vid!

[banzai510(hainz)]

I like this set up. Looks simple

 

the only weak spot is the coupling I think. it may or can come loose.

 

Now I need to get a SU manifold incase I ever want to do this.

KEEP US POSTED ON THIS ONE.

Let us know on the drive around test(with a load)

[Just Joel]

Sweet setup... +1 on price if you don't mind. What’s the new motor specs?

 

Thanks

Joel

I sent an eMail to Vintage Performance about using these carbs on my Lynx manifold single DCOE manifold and got this response ...

 

With slight modifications two HSR Mikunis can be mounted in place of a DCOE weber. We start with the normal dual carb kit, shorten the extended shafts between the two carbs, remove or shorten the idle speed adjuster on one carb, mount them using the same mounting adapters we normally use, and then use adapters so that the DCOE style air filter can be used. The Quad Mikuni kit uses two of these carb "pairs"'.

 

Way cool ...

[fisch]

I notice on the site they have them set up on MGB engines! That is cool for me because of the 59's C engine. But would also be cool for those with the E1 and J-series. The problem I have is I think just bout any dual carb setup will hit the steering column in the '59.

 

Cool to dream though! Especially the moss supercharger version!

[banzai510(hainz)]

I like these as they have a acell pump.

 

This might put Z Tharapy out on the street. Why spend money rebuilding a SU when you can have new/w accell pump.

 

Make sure you have full throttle on that linkage.

 

 

WHAT WAS THE PRICE????????

WHAT WAS THE PRICE????????

 

Basic kit for my single weber DOCE application was $795

[banzai510(hainz)]

imtb

whats the price for that set up?

 

dryheat get a photo of your set up. like to see that one.

[imtb]

Price: I think it was about $700.00.

 

Dryheat I talked to him about using a single DCOE manifold with one carb but it was going to be more expensive and the he thought the performance wouldnt be as good with just one carb. so I found the SU intake and went with that. and very pleased with the performance and simplicity of them.

 

I had DCOE on my other L20b and the new carbs are much simpler and work way better. I could never get the webers dialed in and spent a ton of money on jets and chokes and you had to buy 4 of everthing and SU's I dint spend enough time messing with them.

 

I am wanting to post a video except I sent my dizzy out to be recurved and its going to be a week before I get it back and the weather here is cold and snowy(sucks). I will post one as soon as I get the dizzy back.

 

I can say the carbs are super responsive and sound excellent.

 

Engine build is as follows. LZ2.2Liter 10to1 Compression

 

L20B bored to 87MM

Standard Z2.2L pistons

Z2.2 Crank

L20B Rods.

Total Seal Piston Rings

Above all balanced( make for a really smooth running engine)

Milled U67 Head 280Z vavles(Rebello valve job)Have some clicking issues going to check the wipe pattern.

.475lift Isky Cam

Stock L16 exhuast manifold

23Pound Z Flywheel lightend to 20#( Probably wasnt necessay)

225MM Clutch 550#pressure plated( Very Positive feeling)

these carbs bolt up to a SU manifold pretty EZ? the insulator fit perfect between carb and manifold?

 

I should get a SU manifold if ever want to do this route.

 

should Dyno your motor!!!!!!!!

[imtb]

Bolt on was simple, even taking the carbs on and off is easy.

 

I am planning on Dyno the motor want to get a few more miles on it.

 

Right now I switch it over to throttle cable instead of the linkage. Should look cleaner and simpler with the cable instead of linkage.

[banzai510(hainz)]

yes I would like to see photos of the cable linkage instead of the rod, as I never seen a SU set up using a cable.(most if I saw were Hoky)

 

 

Simple and EZ is what I like.(fix it on the side of the road) Here is where a L motor shines.

[imtb]

Here is a couple of pics of the cable. didnt like how it felt and put it back to the linkage. Also here is video i took tonight.

 

 

[TrevDaddy]

amazing sound man. I really need to get over there and talk to you about my build. I found a place selling cannon manifolds for weber setups, and I was wondering if the mikunis can be adapted to it.

[Dirttrack510]

The video is pretty cool. :thumbup: Keep me updated on the dyno run. :hyper:
