Jeff Young's New TR8 Motor

[iambhooper]

... adding fuel injection to a carbed car... now that's a fascinating concept! taking advantage of the change in rules are we? nice

i wonder how many folk will do this to their cars?

[JeffYoung]

Not many can -- check the Spec line, I'm one of the few cars that came with carbs and FI (Bosch L-Jetronic). 300/400 TR8s came with FI at the end of the run in 1981, plus all of them sold in California.

Still a beeyatch collecting all the necessary parts.....plenums and intakes aren't hard to find but all the other stuff (throttles and injectors, etc.) have been somewhat difficult.

can i do that to my car ? might need more stuff keep up now ....looks good jeff , should be better for you . ralph

Remember the Fiat? That puppy 2 was offered with either injection or a carb. Not to mention different size head bolts for each of the heads. I'm probably off a mm or two, but I seem to remember the X1/9 came with either a 13mm or 11mm head bolts on the FI head along. that made it a real PITA if you spun a bearing or warped a head (both of which happened on my car). You had to make sure you matched up your good head to the new block or new head to the old block.... which is how I learned that the motor came with 11mm studs... I was left running the last race with a plown gasket because the head slipped!

I don't know what the Carbed car had.

Anyway, it will be nice to see your reliability improve. Is the new system Bosch or something Brit?

Looks good Jeff, I look forward to seeing it scream, well, or at least moan in anger!

[JeffYoung]

Right now the only sound it makes is the great sucking sound of extracting money from my wallet.

A bit more progress on the TR8:

Are those independent O2 sensors in each header primary...?
