Outer Limits 4x4 Board

Could use a carby rb30 outta gq patrol . They would be pretty cheap to buy.

just get a efi rb30 there like 300 dollars now second hand . At least you can turbo it later without it grenading . Can put on gas also.

If the engine was in a skyline or similar this setup should be making 350-380rwhp but in patrol with 33's might just crack 300 ? Will find out next week when it goes on dyno.

Also i still have a GU 2.8L intercooler and piping if interested .

i sold it mate

Just a quick update. I decided to build a rb30det in the meantime. I hooked up a external line to keep the VCT and the thing is very torquey now even with a HKS gt-rs turbo . Will post a few vids and pics . http://i41.tinypic.com/259k1tw.jpg http://i41.tinypic.com/qqy2vs.jpg http://i43.tinypic.com ...

get rid of the wolf and get yourself a nistune instead. You'll be doing yourself a favour.

The vg30dett is a shit engine . Nightmare to work on and they have a heap of cooling issues and are quite a fragile engine. :rofl: Sorry, couldnt help myself with that load of Bull shit 203KW's @ the crank in std form new from the factory 20 years ago Please remind us all how many 'new cars' today ...

I was gonna say engine mounts because my old gq did the same thing.

The vg30dett is a shit engine . Nightmare to work on and they have a heap of cooling issues and are quite a fragile engine. If you really wanted a v6 you would go the vq30det . vq30det.com. Much lighter , stronger , smaller v6 and alot more reliable. But putting the v6 in is a major hassle as the ...

Its a easy conversion into a gq if you have a 3L patrol to start with. I have a spare engine for sale if anyones interested. Im in Perth though.

Id like to see some pics of that 4.5 turbo ! sounds like a weapon

Air to air is a bit difficult on a GU as the radiator is so wide so its hard to get the piping around . Im going to go water to air on my GU as i think it will be easier then a air to air in the GU. have a look at this kit . http://www.frozenboost.com/product_info.php?cPath=216&products_id=1034 ...

They only drop down into 7.8:1 if the use the vl turbo bottom end. If you use the naturally aspirated 3L bottom end you get a perfect turbo cr of 8.5:1 with the twin cam head. With the right tuning these pistons will still handle up to 400rwhp. Its all about the tune and not letting it detonate ...

some good info there

You could use a vh41 or vh45 nissan v8 using a marks adator plate to mate it to the gearbox. Both those v8;s would be significantly better on fuel economy then a chev or 308

Its running the stock rb25det computer but will put a nistune rom in it soon so i can tune it .No blow off valve as i cant stand them. Yeh the extra 300cc helps a bit down low but if your gonna go to that much trouble you might as use the rb30 bottom end and bolt the rb25 head on, something i may do ...

Ricer boys ? I think thats the term given to honda civics etc not rb engines.

And you use the rd28 crank in the rb25 block to make it a 2.8L twin cam.

There wasn't any decent factory GU engines to consider so i pulled it out and put a rb25det in it from a r33 skyline nice conversion but don't nissan make a 4.5 v8 for the infinity? The vh45 4.5L v8 didnt come out in a patrol and the conversion would have been alot more diffucult and expensive . On ...

Low end power is fine. Its not as good low down as my old td42 gq but once this gets on boost it blows it away and loves to rev.

I thought i might post up a pic of my engine conversion. After picking up a 2.8L GU for a good price i quickly got bored with the rd28's lack of any sort of acceleration . There wasn't any decent factory GU engines to consider so i pulled it out and put a rb25det in it from a r33 skyline . They have ...
