hello there i am after using a bmw 8v k series head on my 998 engine but i am unsure how much it will cost and what modifications are needed and could anyone give me a ruff final price and whats involved

[Bungle]

i cant help with the how much but have you read the BMW head conversions in the projects section ?

have a read there and any questions should be answered by one of the guys building one of these engines

sorry to be the one to say this, but search, wolfys asked this before and had quite a few decent replys

[wolfys_mini]

i did indeed

are you a millionaire?

the cost vs gain it wasnt worth it

well what i am after doin is building the head to go on my 998 and because my brother is puttin a vtec into his mini i will be havin his 1275 which i will be boring out to 1430 and will want to take the bmw head off my 998 and puttin twin weber on the head and put it on the 1430 also my mini isnt unleaded i thought might as well do it because the bmw head is unleaded also what mods have to be done to the head to make it fit?

the 1430 isnt a straight overbore theres a new crank and cooper s con-rods to be added to that!!! minimum!

the heads are cheap and use bike carbs or injectors and ecu, i dont think webers are available but could be wrong,

i think you maybe thinking of a seven or eight port head, the difference being that the bmw is overhead cam, new timing parts belts and machining is needed to fit the head oil pipes + electronic oil pump and fuel pump,

7 + 8 ports are drop on(sort of), different cam and exhaust on 8 port needed,

the cost is very high indeed, id say 1500 for the bmw / 7 port conversion and about 3000 for 8 port!!!

? :S

yeah i just finished readin a topic on there but i was just wondering if anyone could give me a ruf price cause i need a new head just after christmas.

all the parts that need to be welded to the head are they to stop the block from needing as much maching?

[mini93]

i was looking at how much space id have between the k1100 cylinder head and the front slam pannel, morspeed do an inlet manifold, but is more like a spacer, its only 1 inch in length
designed that way to keep weber carburettors under the bonnet without mods
i was going to run 35mm jenvy throttle bodies which also run weber DCOE stud patern...now im just going to make my own tho

[blister]

i want to have a very fast 998 just want to show off lol

could i have someone give me a list of things that the machinist has to do so i can get a qoute

[mini93]

do you have the specialist components guide book? or know who has one? interesting read and tells exactly whats needed, look at specialist componts site for kit parts and prices by the way

[blister]
