Upgrade L28 CAM and ITBs

Recommended Posts

Hey I have a fuel injected L28 with a megasquirt ECU.

I'm leaning towards a mild cam upgrade, OER ITBs, and headers/exhaust. 

My one question is if there is anything I am missing between doing both the CAM and ITBs. Are they going to be working against each other when it comes to performance? will it bog down in a certain RPM range?

It really comes down to the ECU and the tune you'll be running. I don't see why the cam and the ITB's will be at odds with each other, you might loose a little bit of low end with the 45mm bodies, but should be good to tune out. 100% you'll need a good tuner and a lot of logging to get these things running correctly. Should make for a rad engine!

I would suggest you don't go mild on the cam. People tend to undercam L series. I had a .490/280 cam which I ran on a stock compression L28 with SU's and it was great. When I moved up to triple 44s I felt like I needed more cam. Then I went to a higher compression shortblock and I REALLY needed a bigger cam (wouldn't run on pump gas). Never got around to it and went V8 instead, but I was looking for something in the 300 to 310 duration range.

Fat fingered the reply.

 

There are a ton of variables that will play into bogging or regressive performance. If you open up one aspect of a breathing motor, another aspect will become restrictive.

 

Each category of restriction has completely different behavior sets both in and outside the performance envelope. A manufacturer builds a balanced system but only until every other upgrade possible is equally or complementarily upgraded does the system behave like a fully capable and balanced system again. A lopsided system will perform in a lopsided manner, even if an upgrade is present, just like with suspension.

 

The best answer to early inquiries usually sounds a lot like "how much performance do you want to spend?"
