new to the forums with a ride that's different.

[Jaws]

Hi,

The names Jaws, for people who dont know me I drive heavily modified VB with late model VS running gear.

www.ecotecvb.tk

Now your probably asking urself what's this guy doing on this forum?.

Well the thrill of the v6 has worn off and I need an engine upgrade that has plenty of potential.

The RB motor is by far the best without having to go for a V8.

I recently purchased a R33 GTST 2.5L top end which is to be put on a RB30 bottom end.

The 2.5 head has had a full machine, mild porting and new valves and gtr springs fitted.

I reckon 600 horses should be plenty for the street in a car that weighs 1270kgs.

I have had plenty of experience with the likes of SR20's in race cars, track and rally so nissans are nothing new to me.

Before I registered I had a good look around this site, since so many people are doing the 3.0l conversions this would be the perfect oportunity for me.

I need some feedback on a few areas.

What is better suited to my combo?, apexi fc comp or autronic?.

Did the standard r33 fuel pump have to be upgraded and also injectors?.

What manual gearbox is best suited for this setup?.

What turbo is best suited?, mind you it has to be responsive down low.

That's all i can think of atm.

apexi power fc represents better value for money. autronic is alot more expensive. comes down to preference

fuel pump def needs upgrading, to big bosch item, ie 044

r33 gtst is perfect box for ur needs

search forums for a turbo

[Merli]

Autronic.

No, the standard fuel pump and injectors won't support 600hp.

None, the torque from the 3L will smash the manual gearboxes for breakfast unless you drive it like a pansy. Get a trimatic, or drive it very carefully and don't slam home the gears.

What turbo? That's upto you mate. For 600hp, look to a GT3240/T04R or Trust TD07/T78

I agree with Merli's comment wholeheartedly...

[Elithrar]

Or get a strengthened set of gears for the box made up, or one of those expensive dog-boxes.

[gts4]

Cant wait to see what you come up with

That is an excellent job on the int, Now you are going to get a Decent Motor LOL

Well Done

[Sumo]

Nice mate, will keep an eye out to see how you go with it.

[Bass Junky]

JAWS!

I remember you for the Commodore Forums. I used to drive one, but I saw the light and now drive a skyline.

Good luck with your comvert, the one in your VB is awesome!

BASS OUT

i think a rb25 box can handle it if not driven like a idiot.

[Merli]

i think a rb25 box can handle it if not driven like a idiot.

Sure, it can handle 2000hp if driven carefully enough.

But why would you build a motor like that and not drive it hard? Would you never drag race it? What's the point? And he's a commodore driver, of course he's going to give it a good thrashing every traffic light. :D

OH WOW with exactly what Jaws is proposing (RB30 bottom end, RB25 head, T78 turbo) smashed 2 RB25 gearboxes in 2 weeks.
