Hi guys,

Only new to the forum. I need a little bit of help. I know absoloutley nothing about the RB engines but i was told their a good engine to extract power from. What im chasing is and engine i can put into my ford escort for the car show coming up early next year. Im chasing 750HP and was wondering if you could give me some advice on what engine id be better of going with. Of course im going to stroke it and strengthin it but im wondering what else as well as what turbo set up (twin turbo).

Thanks, I hope you guys can help me out

that much, really?

I was gonna go one of these engines cause i was told there cheaper then a v8. I didnt realise this

Yep, it's an expensive trip.

I could tell from your first post that you perhaps had not looked into it, as if you really wanted to be running 750hp from a 2.6ltr, you wouldn't be asking on the internet first :)

You'd be better off with a 2JZ IMO. Plenty of bolt-on cheap from the US.

V8 is WAY cheaper to build than an RB26.

And V8 would fit in tiny Escort engine bay easily I'd imagine.

Plus not sure if 750hp in very light car is necessary but each to their own.

This.

The RB's are good at getting respectable numbers, yet 750hp is a little far and beyond from the term 'respectable' - more so phenominal.

The 2JZ is a better platform for that kind of power out of the box, as the others have said its more or less a developement thing.. You will need to sink a LOT of money into a motor for that sort of power and YES a V8 will do it a lot cheaper.

A 1JZ with a GT4092R will do it 'unopened', a quick run down on prices as a benchmark:

5k on turbo, manifold, gates, lines, gaskets, bits n bobs JUST to fit the working turbo to the motor

5k on management, ecu, injectors, sensors, 2 fuel pumps, lines, tuning

5k on engine perpherials, cams, belts, intake manifold, balancer, pulleys, etc

4k on an intercooler and exhaust

2k on a clutch that can hold that power

The 2JZ and V160 gearbox will set you back over 5 grand on its own.

As a rule of thumb, the respectable threshhold of all setups probably stops around the 500HP mark. After that you will need a 3.5" exhaust, 2k intercooler, two fuel pumps, excellent management and a VERY strong motor.

Maybe rethink the power your chasing and go from there. A well sorted 500HP Escort will piss out 10s ;)

FYI 500hp is also pushing it for the RB, again think JZ or V8.

either way 750hp power is goin to cost a SH*T load of money,

cheapest way i could think to get somewhere in the ball park of 750hp would be to get an LS2 (6L V8 out of a commodore, suprisingly cheap). get it built to handle boost

and slap on a turbo or Roots type blower. There are places that will do a full stroker kit rebuild for under 10g and the turbo/super charger kit is goin to be around the 10g mark

So even then ur lookin at 20g plus the extras. You could probs get close to 600hp with a stroked 6L with some head and cam work

thats if it fits in ur engine bay of course heh heh

Jump on the LS1 forums if ur keen to go that way, those guys are pretty helful

some would say a Neo Rb25 would do it un opened too.. (well maybe arp studs and MLS gasket) mercury motorsport proved this not long ago with 700 rwhp from a stock bottom end.. still going too.

can get brand new ls3 crate motors complete with manifolds and sensors etc (just no wiring loom or ecu) for around 5-6k. wouldnt take too much work to get 750hp, hell my brothers makes just over 500bhp straight out of the crate (came with a bigger cam)

At the wheels mate?

I would believe it. My mates ls2 made 460hp at wheels with cam + extractors etc

Even with a stroked/camed/ higher compression LS3 your not goin to get 750hp.. if u even got close it would be shit to drive due to the massive cam

LIke i said before i reckon u could get close to 750hp for a bit over 20 grand.

Does it really need to be 750hp lol?

no way at the wheels, my brother just did $10k+ on his new malloo with LS3, all new race heads, big cams, cool air induc, extractors, exhaust, tuned and tuned and got 460rwhp, when you already have 6Litres I don't think the extra 0.2litres makes much difference..

should have gone under bonnet supercharger, for $10k could get close to 750bhp, or maybe closer to $20k

I think this guy needs to drive a few different cars with varying engines and weights etc.

For example on the weekend at our motokhana we had a 180sx with a 4.5L (i believe) V8 in it, makes 200rwkw. The thing was a fkn animal - no way does a car of that weight need anymore power to be fun.

Devo. The one im talking about made 256kw with stock cam and then 353kw with only the cam and tune changed

      Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy.

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.

      Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
