grillbar Posted November 22, 2009 Report Share Posted November 22, 2009 Hey all, I've recently got my hands on a ke35 and I'm making plans to do en engine conversion, I was thinking of going with a 4age or a 3t-gte, if anyone who has done this before could help me out with what type of problems they encountered (if any) during the conversion that would be muchly appreciated cheers grillbar Quote Link to comment Share on other sites More sharing options...
kiahn Posted November 22, 2009 Report Share Posted November 22, 2009 well chassis bracing with a 3tgte would be a must and also new diff and basically all the driveline, i do believe you would need custom tail shaft and butcher a gearbox crossmember 4age can be dropped in by changing the engine and gearbox crossmembers over to ae71 items and also you wont need to upgrade your diff(although it is recomended) simply put if you want simplicity go the 4age, if you don't mind putting in a lot extra money and time then 3tgte ftw (also you get ALOT more power) Quote Link to comment Share on other sites More sharing options...
RedKE30 Posted November 22, 2009 Report Share Posted November 22, 2009 (edited) Gearbox x member from AE71 is not a straight change over to KE30, and I think KE35 would be the same? Needs to be modified a bit to make it fit. I wasn't aware that an AE71 engine x member would bolt straight into a '35 either. Glad to be corrected.

kiahn Posted November 22, 2009 Report Share Posted November 22, 2009 yeh I'm pretty sure the engine crossmember does goes straight in, i saw a ke30 4age and it didnt look modded at all Quote Link to comment Share on other sites More sharing options...
grillbar Posted November 22, 2009 Author Report Share Posted November 22, 2009 how about a 4agze? what common problems would one encounter when installing into a 35? Quote Link to comment Share on other sites More sharing options...
greenmac80 Posted November 23, 2009 Report Share Posted November 23, 2009 No an ae71 x member will not bolt straight up. will need modifying otherewise anyone whos done a 4age in to KE30/55 etc. will have done it. custom mounts are needed for the engine however the ae71 gearbox x member will bolt up just fine. 3t gte will make the car quicker due to being turbo. 4age is a newer engine and aftermarket support is huge for them.

greenmac80 Posted November 23, 2009 Report Share Posted November 23, 2009 i should add that the ae71 gearbox x member will be a direct change over with a 16v 4age but for a 20v it needs modifying Quote Link to comment Share on other sites More sharing options...
oh what a nissan feeling! Posted November 23, 2009 Report Share Posted November 23, 2009 well chassis bracing with a 3tgte would be a must chassis bracing??? um, no. Quote Link to comment Share on other sites More sharing options...
beerhead Posted November 23, 2009 Report Share Posted November 23, 2009 Hmm doesn't sound right mate, both run the same gearbox, so I'm not sure how with a 20V it'd require mods if you delete the dizzy cap. i should add that the ae71 gearbox x member will be a direct change over with a 16v 4age but for a 20v it needs modifying Quote Link to comment Share on other sites More sharing options...
RedKE30 Posted November 23, 2009 Report Share Posted November 23, 2009 My AE71 gearbox x member didn't bolt up to the chassis of the KE30 full stop, without an engine/gearbox being in there. Quote Link to comment Share on other sites More sharing options...

I took beerheads post to mean that there shouldn't be a difference between a 16V and 20V conversion as they both use the same gearbox, thus the same gearbox x member, which doesn't bolt up to the chassis. It's not a matter of which engine you are using as the AE71 gearbox x member will not bolt to the chassis full stop.

Interesting...was yours auto or manual originally? As far as I know mine was a factory manual KE30. Quote Link to comment Share on other sites More sharing options...
SLO-030 Posted November 25, 2009 Report Share Posted November 25, 2009 Does your gearbox X-member use 4 smaller (M10,12mm head)bolts or 2 large (M12,14mm head) bolts. If you have 4 smaller ones you have an auto X member in an originally Auto car. If you have the 2 larger bolts you have the Manual X member in an originally manual car. The AE71 X memeber will bolt up to the Manual X member mounting points. The auto X member is a fair bit further back than the manual member. AFAIK, Auto Chassis' don't have the manual mounting points and Visa Versa. Quote Link to comment Share on other sites More sharing options...
