When An Rb Is Just Too Big....

I'm looking to design up a small roadster type thing, similar to the small kit cars you see getting around but I'm going in a bit different direction than most in that I want to use R32 GTR running gear with shortened axles and drive shafts etc. My problem is that the RB26 is just too tall for what I want to do, and to be honest it's too heavy as well.

The main problem I have is size, I want something that is short in height and length so the car doesn't end up huge.

Ideally a small ally NA V6 would be great, but I have no idea what's out there. I was even thinking a rotor because they are so small but I think I would prefer something with a little more torque. I'm not too fussed if it's NA or turbo but NA would be easier. I'm thinking around the 230kw mark, which should make for a quick car.

What can you people think of that fits the bill?

Cheers

Aaron

they make a clubman, lotus 7, prb thingo called the wasp which runs an sr20det in them

they are one of the quickest things around because they weigh nothing but as the sr is too tall they have to be dry sumped.

my mate had a variant with a rolla 20v and just low enough.

we queried going 13b but its too hard to make them fit the emmission specs for what is essentially a 'new' car.

his prb with the race spec 20v was bored and stroked to 2.2L with ITBs and race fixed cams, made about 240hp at the fly

throw it in a 400kg car w/o driver and you end up with a sub 1.16.xx mallala laptime

he has since built another with the 16v as his weekend car - more than enough balls to drag off a 911 and still handles better than a lotus

Renesis 13B - not a torque monster, but certainly not bad. With decent exhaust and ECU, you will have it easily over 200kW. As it's a current model engine, emissions shouldn't be too much hassle. 9000RPM from the factory should be enough, too.

Alternatively a 13BT will have all the torque you need, with 500hp readily accessible.

If you are looking for 230kW from a small, compact engine, then I suspect that you will have trouble with emissions / driveability / lag at any rate, so from that point of view, a modern rotary won't be too bad.

If it's all out NA grunt you want, then an L98 is the go. Lighter than the RB, with an easy and reliable 500hp available with little outlay. You should be able to pick up a brand new crate motor for around $6k or so. Problem is they're fairly bulky and tall, so might not fit your purpose, and the T56 is heavy, and a bit of a p-i-g (it changed it to cop :P ) to use.

how big are the motors out of toyota aurions? They use those in the lotus evora and if the engine itself isn't too large/heavy i could see it being all kinds of awesome.

Also aren't LS motors shorter and lighter than RB's? Although unsure on how tall these are either

If I were you I'd be looking at RNN14 GTi-R or HNU13 Bluebird running gear and SR20DET's, they're the most potent version of the engine and they're AWD (albeit not ATTESA-ETS like the GTR, but close). Was good enough to conquer rallies back in the day.

Not a fan of the east west in a GTi-R plus with the GTR running gear I can swap to rear wheel drive if I feel like it.

A 13b rotor is looking like a likely contender at the moment. If I run e85 emissions shouldn't be to hard

Got the ticket right here...take 2 suzuki hayabusa engines and turn it into this 2.6 litre to 3.0 V8 that turns to 10,000rpm. :)

...Or if your soft just the H2 engine.

      The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter

      Single Turbo Conversion On R32 GTR.

      By Duncan · Posted

      Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
