wtb dsm 6 bolt

i started researching the compression differences on the turbo vs non-turbo and i says the non-turbo 1g has 9.2:1 and the turbo has 7.8:1. the turbo 2g has 8.5:1. does anyone know if there is anything wrong with the 1g non-turbo block. i know if you run to much compression with a turbo it with knock but besides that do the blocks have many differences? can i swap turbo parts on a non-turbo 4g63? head bolts/manifold bolts and so on? If the blocks are just as strong on the 1g non-turbo 4g63 i would rather go with that block. any arguments? also i noticed the bore and stock are slightly different on the 1g engines( esi and tsi) but both have the same displacement.

The blocks themselves are identical other then oil squirters.

^^^^are you talking about the 1g and 2g?? i was wondering on the 1g esi and the 1g tsi. because the compression ratios and bore/stoke are differant but i should be the same block right? I just wanted to make sure because of the minor bore differences. thanks

I was referring to the 1G turbo and NA 4G63 block. The 1G base model was a SOHC and used a different block, i believe that was the DL model.

^^yeah but that was a 1.8L. do you know if the turbo blocks were build any stronger?

Did you not pay attention when i said they were identical other then the oil squiterters.

k thanks

bump. still looking. I would like to get a motor from a non-turbo 1g. It would be nice to get crank/rods/pistons/block all together. thanks

[beachbum_jon]

um...didnt the turbos and non-turbos have different pistons?

[GnArKiLl]

yes Jon non turbo's had higher compression pistons

[beachbum_jon]

yeah thats what i thought, but if i wasnt mistaken he wanted to buy a whole bottom end of a non-turbo for a turbo car...

yes i want the whole bottom end of a non-turbo for a turbo car just for the fact of a little higher compression.

[beachbum_jon]

alright just clearing it up for my self

umm....

(1) NT pistons cant handle more than 8-10psi due to the ring lands being so high on the piston. If you want a higher compression turbo motor....put in higher compression TURBO pistons.

(2) A 7bolt bottom end cannot fit in a 6-bolt block. That whole point of going to a 6-bolt is to get away from the 7-bolt bottom end.

thanks this is exactly what i wanted to know. one more thing is 2g rods/pistons-can they work with 1g crank? and thanks agian for the information.

[GnArKiLl]

pistons- yes... rods-no

[black2g]

k thanks. so the rod journals are different for the 1g and 2g's. thats cool. thanks alot man

[black2g]

bump. i think i found a block. i need a crank now. anyone???? 6 bolt 4g63 crank

[GnArKiLl]

i have 2 of them make an offer...
