2TG 88260 Head and Cam Question

[71TA22]

Looking for some info from the 2TG guru's.

I have a 2TG engine which I took from a euro spec TA23 GT.

Head is an 88260 with single valve spring's, 88222 cam's and carb's (PHH 40's). It's all factory standard.

I know that the 260 heads got fuel injection. They also got double valve springs at some stage during the production run (about July 1977).

I am interested to know if the cams were changed during the 260 production run and if so what to? Was there such a thing as 88260 cam's or did they use the 88261 cam's?

maybe someone change 222 cams, because more timing and lift, also single springs have higher seat pressure... they really are single ? not double without inner springs ?

and carbs from 222

222 is most powerfull stock 2TG engine. maybe there is 222 9.8CR pistons also ?

The engine with 260 head came from the factory with the 222 cams.

Definitely single springs. The spring seat and retainer are for single springs.

Carbs are the same as for 222 head.

9.8 CR pistons.

Checked the euro parts manual and this confirms that virtually all the TA23's with 260 heads had all the same parts as TA23's with 222 heads. Only difference was last month of production in July 1977 when the 260 heads got double valve springs.

Change from 222 to 260 head was in January 1977.

so those are "mixed" in toyota factory, first they got new desing head, then change cams springs ..... never know that

all of my 260 heads have 260 cams also... but imported engines

Did your 260 heads have fuel injection or carbs?

I'm thinking 260 heads with fuel injection got 260 cams and 260 heads with carbs got 222 cams.

When was 261 head introduced - date and engine number?

When was 262 head introduced - date and engine number?

i really dont know which one is it, because i have been buy blown engines in pieces.

But later heads with efi intake there is one more bolt in intake flange. and i have that type heads, efi intake will bolt on, in all holes.
Early type head with EFI, then there is one bolt place to much in intake


hope you got what i mean to tell

I understand.

260 head with carbs has unused intake stud hole which is needed for EFI intake.

[71TA22]

your head have that one extra hole ?

Yes, my 260 head with carbs does have the one extra hole.

[J-M kujala]

never seen that kind head. (had to check my heads )

[71TA22]

Unused stud hole on 260 head intake side - behind carb balance pipe.

[J-M kujala]
