cams and turbo.

Hi guys, It's been long time since i looked into this site and also posted.

Anyway, I've been thinking seriously recently to put in a tiny turbo for a soft boost to help take off
but not looking for a huge boost since the samurai wasn't made for racing along the highways anyway...
After talking to some of the mechanics, I decided not to since it's gonna cost some money just for fabrication.

So, I thought that I amy put in a new cam.....but MY QUESTION is that "by putting a new cam, do I need
to also change new seats for where the cam lobe contacts the thing that lifts the valve?"

My reason for asking is that since the engine has been stock all this while, it have a wear pattern
that will definitely be different from the new cam (no wear at all). Will changeing just the new cam cause me to
have to work on the clearence every now and then till the wear pattern sinks in?

I know it's impossible to have top end speed and huge torque at low end with one cam. I am looking more into
torque at low to medium RPM (between standstill till 3500) and also trying not to sacrifice the top speed.
The engine sees constant 4000 rpm on freeway and sometimes when I feel wild, it sees 5500 to 6000 RPM

Anyone knows of the type of cams I should get? I see that Glenn of Summit Offroad offer two type from Iskenderian Cam
and at the same time, Dave of AZ sells a larger selection of cams from AAPAwith various RPM ranges.

Dave's range of cams even confuse me more....

Please reply soon as my brother is visiting me and hopefully I can get him to buy on from USA for me.

Can someone steer me to the correct cam?

Thanks in advance

Re: cams and turbo.

Hi,

Thanks for replying but I don't see any 1k to 5k cams being offered there... Am I missing something?

Re: cams and turbo.

Here is the catagories from Dave's site.

1) low-end (1000 to 4500 rpm)
2) low-end/mid range (1500 to 5500 rpm)
3) mid range (2500 to 6500 rpm)
4) full race high end (6000 rpm & up)

Re: cams and turbo.

Go with the low end/mid range torquer cam from Dave at Asian Auto. Yes, with a new cam, you must replace the cam follower/rocker arms (they are made together). Dave can help you out with that as well.

Re: cams and turbo.

I seem to remember someone saying either here or on a T-Bird BBS that changing the cam may adversly affect how the Electronic Computer Module (ECM) manages the engine. The ECM wants things one way and the new cam kinda throws a monkey wrench into what the ECM is doing.

I would imagine that this would not be a problem with an aftermarket carb installed and the ECM disabled.

Any comments from those in the know?

Re: cams and turbo.

"by putting a new cam, do I need

only if they are worn beyond specs. most are not......when most people install our cam or any new cam, they run their engine at between 1500 to 2000 rpms for 20 min. to break it in.

we have been playing around with what cam works best for different set-ups....and the wild thing is the best all around cam for carbed or efi Zuks is the low end cam.....it's not majic......it's simple.....it has more lift on the exhaust side and not much at all on the intake side....thus not screwing up efi....and providing more exhaust to exit......bam! more power....on the low end it has grunt....and will not float out on the high rpm side. Our low end cam is like the big V-8's RV cam.

but if you want to race, and have dual carbs, and small tires with stock gears, then a high end cam may work for you., but no one with efi that I know of has made one work yet.

on a side note.....we are working up a production EFI for all 1.3 and 1.6s that will work with any cam...this will allow those with EFI 1.6 16 valve engines to get even more boost! it will allow guys with carbed 1.3's and 1.6's to bolt on an EFI that will also work with a high lift cam.....it's sooooo cool....lol

we'll have this set-up ready for market in about 60 days or so....

Dave

Re: cams and turbo.

please post details about your new EFI.


it's multi port with an adjustable control module, we had to install the injectors in a modified intake manifold....

we're working to keep the cost down, by getting several made up at once....and sorry Geoff...Eric is going to test the second one for a product review...LOL

Re: cams and turbo.

Dave,

First of all, thanks for replying to my post. You mentioned that best all round will be the low end cam meaning the one rated between 1000 to 4500 rpm.

If I get the cam, can it see constant 4000 to 4500 rpms on freeway travel for a couple of hours?
Can it also touch 6000 or 6500?

or is it safer to get the low-mid range?

Do you have either the low cam or low-mid cam in stock?

Thanks.
