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?

At the wheels mate?

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

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

    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
