will a holley and a set of extractors help my rb30

[Alitis007]

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?

Like i said mate all the same just different cams.

Personally i'd go turbo, not over the top but just with a couple of mods to give it a better economy. My vl only ran standard boost but had a lot of down low torque. Because it was a high comp engine i installed a 1.9mm thick layered steel head gasket to lower the compression and also got the valves enlarged by 3mm, on stock boost and a cooler i could run the factory computer.

Imo efi is good but that little bit extra from the turbo will help ALOT!

sounds good, efi first though.
how about the lpg?

[Rustyboner81]

The series 1 vl block dont have the turbo oil feed and drain or water line under the extractors

should this concern me?

Its ok but personally i don't like lpg coz it dries out you motor and halfs its life. The only real benefit is that its cheap and if your run dedicated lpg you dont have to comply with emissions but that means no injectors or petrol tank at all in the car so no need for an engineers cert.

Just remembered lpg is 110ron so with a turbo will produce more power high in the rpm torque curve.

Not really the patrol block should have them there and your only really interested in the intake manifold and loom for the conversion, anyway if the trol hasn't got them its pretty easy to drill and tap plus one water line for the turbo is comes from a heater hose. The T piece is easy to make with fittings from pertec, 16mm straight piece the a 10mm fitting for the turbo water line. The turbo drain you can weld onto your sump like the td42 boys do.

I've been thinking about finding a rb30 trol to make a rb28 hybrid but thats just a day dream lol 800hp for under 5k, that would be fun hahaha

[Rustyboner81]

cool, might get this vl today if i can afford it
I run the upper cylibder lube system with mine so that should help

I have just done some web surfing, looking for transmission options. One GTR forum has members that extract up to 1000 hp, (with a LOT of mods), out of an rb30 block. That is insane!

When i turboed my vl, my machinist had a head there that flowed 800hp, all it had done was a small port and polish but mind you it was a dohc rb25/26 head. Combined with an rb30 block you make a hybrid RB28, the same used in the limited and very rare R34 GTR Nurspec. There also was an R31 skyline drift car running a standard na rb30 bottom end with a rb25/26 head running hi boost for ages aswell.

I've also been researching transmissions, and the common word is that the mx7 box was rare, even in 2006. Is there a gearbox reco mob that aren't too expensive and you trust to do a good job, George?

The patrol box will handle the power. The vl na box is a carrat.

Not really mate, thats why i try and do as much as i can for my customers and mates. From memory there was a couple of recoed boxes on ebay but they where asking top dollar. Another alternative is retro fit a supra 5spd but you would probably be up for the same $$ as a Tremec 6spd.

Why can you fit a TB/TD42 box and change the bell housing??
