Hey, George, what can be done to toughen up the gearbox to make it handle the extra ponies from the upgraded engines?

Do they run a MX5 gearbox like a vl ?? If they do i would source an MX7 vl turbo box to bolt up to the transfer case. Be prepared for the MX7 to be worth around the 2k mark.

A bloke from one of the gearbox and parts suppliers reckons my troll has exactly the same as a VL, when I gave him the VIN. So I may be able to upgrade the guts to the MX7,yeah?

Most definitely mate, i think they have wider gears, so a larger surface area to spread the power across. If you wanted to go a bit over the top, why not fit a Tremec 6 speed from a vy commo /ba facon?? That would be pretty sweet hey ??

[mudnut]

Yeah, it would be sweet as, but the wallet is gunna be anaemic after whacking the secondhand box and trans case and new heavy duty clutch in. I will be doing up the old box when funds permit.

Thats fair enough mate just put Tremec 6spd on the to do list

Do you want to put a efi upgrade on your RB30 ??

yes!!!!!!!!! im waiting to hear back about an R31 wreck with good motor but rooted radiator unlicensed $300, and a vl commadore licesed $800

im quite confidant that when i get home in 10 days i will have the donor.

so i would really like a "how to" thread or link to help me do it

im planning on just changing the head and the components not the whole engine

if i dont need to change the head then even better

The head is the same vl na and turbo , r31 and patrol. The cam is the only difference between carby, efi and efi turbo. The series 1 vl block dont have the tubo oil feed and drain or water line under the extractors but the series 2 and all r31's do. If you want to turbo the motor a series 2 (mid 87-88) vl loom is better coz it has the extra wire needed to wire up a knock sensor already in it. If your also going to run a turbo and are not going to get it engineered use the na pletnum chamber because it has bigger runners in it than the turbo one coz the turbo unit is from an rb20 sohc that the vl's and r31 use in nz, but we scored it coz of our awesome emission reg's. If you want to squeeze another 7kw out of the motor you can also get an XF EFI throttle body and match port the manifold to suite, but you dont feel the benefit coz its for top end performance.

Its not that hard to do just finding 20 yo parts that are in good working order is the problem i actually have a turbo set up that i used pieces from to do my vl turbo conversion on my old vl ex cop car that i had AND the na set up aswell lol

so i can leave the carby head on the rb30 and just attach the intake manifold etc.
if had my head off before i know it runs well
i was under the impression to go efi i would need an efi head?
