Thats what I thought you had said

yes, definitely a Datsun 1200 GX head aka "1200GX", superior to the JDM B210 twin-carb heads.

Wow this was an old post I never ended up getting the car or engine, I do have another gx if you need some parts.

DD that head that I should you when you came to my shop was that a true gx head??

Yes that's right. USA model "GX" B-210 was only a trim option. It had the standard motor. In Japan they had the A14T twin-carb engine.

greasemonkey - are you saying that the car is a "B210GX" - if so, it doesn't have a true GX motor like the kind your probably thinking it is.

I sold earlier this year, well last now, a 77 B210GX that as far as I know it was just a standard A14 motor w/a 5 spd. in it. No double valve springs, dual carbs, no goodies other then standard.

I think it was just the badging & a few options on the car that made it a "GX" model - enhanced interior, 5 spd., tach, etc... not high performance engine.

just my 2 cents worth.

evan

where are you?

hey grease just a curious question about that b210 if thats the entire car i could use the seats both driver & passenger no matter the condition.
it make my b210 a complete classic,rev5th

The 1200 & A12 GX cylinder heads certainly have the largest ports of the production cylinder heads, but they have the smaller valve sizes while the 'good' A14/15 heads have a slightly smaller port size, but larger valves, so what you lose in one area, you pick up in another. Quote:There were no 'optional' valve sizes. The smaller sizes were used in the A10, 1200/A12 heads while the larger size was used in the A13/14/15 heads
As for the A12A, ... beats me.

There was a round port head with the GX/A14/15 manifold bolt pattern that was used on the 'economy' version of the A14 engine.

The right drive JDM GX models all came with the twin carbs, however the left drive models seem not to have been able to use this induction due to interference problems & any left drive car with the GX label will have a standard single carb engine.

The gen-u-ine GX cylinder head will have the four coolant holes under the inlet ports as per the photo in d1t's post as these are required to provided heated coolant under the inlet runners of the dual Hitachi manifold.

well thats what the owner told me that the engine was out of , so its probably not a true gx head

Quote: I thought that you had already determined that it was a GX engine.
Even for a regular A14, the price seems good enough.
