 mmost F&F Wolny Słuchacz :) malec Gdynia | 2006-10-27 21:05:07 It also depends on the expected power and torque. Most of 1.2 swaps I've seen are based on a 126 gearbox. So it should be sufficient to 75HP and about 100Nm. But it probably depends on the way you handle it. Serial clutch handles about 75Nm max if handled carefully. And the weakest element of the gearbox are the elastic joints conecting rear wheels to the axels. So even if you would use the original gearbox, you would probably have to replace them with something stronger. Good luck.
And may the force be with you  |
mmost F&F Wolny Słuchacz :) malec Gdynia | 2006-10-28 23:52:06 there is a company that sells theese joints (also click here), and theese should do nicely, but anothere alternative is simple and cheap. it's replacing the bell shaped, cast iron element connecting the axle with the elastic joint, with another elastic joint. it's common in rally 126s. this way the joint is twice as elastic as the original one.
and by the way, remember that a smaller engine volume produces less exhaust gases, thus the the turbo charge will probably be not as powerfull as expected if you have any ather questions feel free to ask i hope to see some pics
good luck ps you should also be awere of excess heating due to increased power

mmost F&F Wolny Słuchacz :) malec Gdynia | 2006-10-30 12:04:16 if you need any hints with the oil cooler, feel free to ask , a by the way: how do you intend to supply oil to the turbo?? (curious) |
sasuke Seat Ibiza FR, Fiat ... Bratislava, SVK | 2006-10-30 13:49:09 Well, if you know a cheaper alternative as buying this  - extension to the timing case with the outlet for oil cooler (cca 190eur) then I would be very grateful. The turbo is from 'phase 1' - cooled only with oil, I simply wanted to enlarge the oil circuit to engine->turbo->oilcooler. It is in the same way like on the R5GTT.
There are some photos of upgrade components at my page Fiat 126 TURBO, but I didn't make any new photos recently, and it's written in slovak 
Have a nice day! |
mmost F&F Wolny Słuchacz :) malec Gdynia | 2006-10-30 14:32:43 i do know a cheaper alternative my whole oil cooler do-it-yourself-kit cost about 75euros. all you have to do is buy a new timing case cover, weld some aluminium on it, drill a hole, make a thread, and voila however if you're mounting a turbo some extra filtering of oil would be nice.
click "chlodnica oleju" it's in polish, but the pics should tell you the whole story, but as i said: instead of just drilling a hole in the cover, weld some aluminium on it so it looks more or less like that : 
an by the way, if you are really thinking of mounting that turbo, the making your own oil cooler shouldn't be a problem

Can anybody write me what gearbox should I use? Or what modifications should I do in order to make the original gearbox stronger?
That's OK beacuse the engine simply isn't situated for such a high pressure. 0.6-0.7Bar will be nice.
