Different Prechambers PIC

[dankcorey22]

Okay im getting everything on my head new tomorrow. Im using a head off a 1.6 NA my engine is 1.6 TD

Doing last checks tonight to make sure i have everything i need i found out the prechambers off my 1.6 TD head is bigger than my 1.6 NA head PC
Will this head still work ive already spent countless hours porting and polishing this head 

I hope this thing will work for me

The one on the left is TD the one on the Right is NA

I don't think so. I thought the ones with the ding in them are TD??? At any rate one is 30mm across and the other is 32mm. Unless you have an inconel stretcher I would say it won't work as planned.

The ones with the ding in them are smaller i got that head off of a 1.6 NA in the junkyard. The Bigger is the head that came off my car. It was cracked

Yep, I've only seen the little dent on TD engines.
 Letter at the end of the head part number?

the 1.5D and 1.6TD share the same diameter cups. the n/a got the bigger cups..

[dankcorey22]

maybe that car i bought with the TD engine had a NA head on it. Or maybe the Head i got from the junkyard was a TD head on a NA engine.

IDK... It blows my mind. I believe you all but its backwards from what im experiencing.

Anyone have any comments on it? I sent it to the machine shop today they said it really wouldnt make a difference maybe the CR just a little.

[theman53]

It will make a big difference. The smaller cups will fall out of the head!!!! They are only 30mm the bigger ones are 32mm. See if Myke W still has some junk heads to sell the PC out of???

only way is to make the PC bores bigger..

i dont see a 32mm PC fitting in a 30mm hole..

Soo just to be on the safe side ill probably just buy a reman head for the TD.

Great. All my hard work of porting and polishing the intake ports is gone out the window....

Alright just priced a rebuild head: $600 

I dont have the funds now to buy a $600 rebuilt head so does ANYONE know if my head with the smaller Precups will work with my 1.6 TD?

I was only thinking i would spend around half of that with the machine shop.
Im in a desperate situation now lol  I need more peoples input to judge what im going to end up doing
