2A-GE, anyone done it?
|

Ive noticed a few sites in Finland with details about doing this, but its kinda hard to read
anyway, has anyone on these forums actually put a 4A-GE head on a 2A block? and what is involved apart from swapping heads, while keeping it to 1300cc or less?

to comply with class rules in some racing series perhaps.
the KP61 is popular for racing in Finland, they find all sorts of ways to get hot 1300s in them for racing.

i think that would be quite hard to attach a gearbox to, or make RWD using the std gearbox. the gearbox might be prone to breaking too because of the weight of the car

not necessarily so
theres some info somewhere on the net of a lotus 7 replica running a habausa motor
i believe there was a video of it posted on this forum about 6-8 months ago - and was absolutely insanely quick!

bike engines in Lotus 7 replicas are very popular in Europe/UK. Unfortunately we can't do it here because of emisions regs (f'kin Kyoto protocol or something), there are 2 busa powered 7's in Syd though.
The Nurburgring lap record for road registered production vehicles (7m19s) is held by a special edition Radical SR3 running a turbo 1500cc Busa engine.
The wildest bike engined car has to be the Ultima on this http://www.z-cars.co.uk/ site
990kg, 1000hp from two turbocharged Hayabusa engines and 4WD as well.
The bike engined minis look like wild fun too.

I read somewhere that the Hayabusa motor/gearbox only weighs 180 pounds, but makes crazy horsepower like 180 maybe? or maybe it was "only" 150HP?
Seems like the future of motorsport to me...
ultra-litghweight ultra-rpm ultra-HP motors with ultra-integrated ultra-close ratio 6-speed sequential transmissions = sounds like a good plan to me
oh yeah, and that video of the Nordschleife circuit lap record is here... (Hayabusa-powered)
http://www.radicalmotorsport.com/gallery/ring2b.mp g
and here's another video that's fun to watch too... (also Hayabusa-powered)

most classes have rules restricting the use of motorbike derived motors & gearboxes.
i know of a 2age that was built about 8 years ago in NZ that went like a rocketship & beat everything in it's class for nearly 2 years! so it is a good conversion

i need to keep a toyota engine in for class restrictions also
so really its a 4e-fe, K-series, or this option, im just wondering if anyone has done it, and if so if they could tell me what is involved, so i can make an informed choice.
2a-ge would be my preference, because of the availability of good stuff for the head (ie 20v head w quads, TODA cams etc.) or even a 16v head, it will still flow better than a k head, or a 4e head

Thought about 1SZ and 2SZs?
Not sure if they would fit your spec, but interesting nonetheless.
As for the 2AGE, i would say that a 16v head would be your best bet, along with a 16>20v quads adaptor and the quads.
You might even be able to fit 2A crank, rods and pistons into the late model 4A block so you get the oil squirters, and ribs.

I was thinking the same... But my engine builder was having a giggle about the thought of an IP racing engine with this combo or may be 20V... I'll just have to wait and see what mad plan he comes up with.

Why bother for IPRA? The lowest class is U1600 (afaik)

Jezza: what do you want to know about 2A-GE. I have not done this myself but I have been watching my friend building 2A-GE and I can get all the info needed. I just need to translate it if your interested.

0-1600 is the lowest and the nature of the the 20V seems to like higher revs or work better in F/I setups over that of 16V head. 1300cc, more revs which could be more power... Sure I know a 16V 4AGE can and do produce more Hp than a 20V, but we were having a discussion (After way too many bourbons!) on what kind of stupid combo's that could be concieved and that haven't been tried... one was de-stroking an engine to around 1100cc and adding a turbo...and the only catergories that is would suit is IP or supersprints, so why not? And the only way to find out is to try it!

Ah very true, but the longevity of the turbo would be in question, with a 28mm (or is it 32mm) restrictor sitting on the front of it.
Would be interesting though.

Johnny take a look at Land Speed Record MR2. They destroked a 4A 20V to 1000 then pumped a bunch of boost into it to run some serios speeds on the salt flats.

32mm and True, and we live with it in rallying, but there are legal ways around these things... as of late, I've heard these sizes may be under threat due to a few people (namely with GTR skylines) are trying to get them changed The fact that the area of both restrictor have to add up to a total area of 32mm ie 16mm/restrictor which would affect anyone wanting to run a series 6/7 RX-7 or a 20B. Really CAMS needs a change of guard in the racing circle, someone that knows how to improve the sport, not restrict it, I'm very thankful that this has arleady happened in rallying and they are listen to us on what conversion can be legally done for road use(straight swaps!) and they are permitting them.. ie 20V into OZ AE101 (thanks to me!), BP16 into KC and KE lasers, and I know there will be a few others that coming soon... F16 next year is looking like it will be a hard fought title, with more late model, re-engine cars, just what we need and make things more appealing to joe blow. IP need a few more tweaks to give it this.

True, it could be interesting.
Now you have me thinking about it, i do want something to MS+S, and i know where i can get a nice little turbo, but how to get 1100cc out of readily available parts.
4A blocks and heads are nice and easy. 2A crank?

That's about as far as we got  I bet you he'll come back with either sleeving the block or some other concept... this will be another drunken convo  and turbos, well, I've a couple of evo 3's with restrictors sitting in my workshop, couple of GTR's and an MR2 one and I know a mate that has a hoard of SR20 one's that range from way too dame big to stock. If we were to do it, It would have to be as cheap as possible, just to see what kind of combo is needed to make it work, and then improve on this.

Heh, i have a freshly rebuilt TD02 which i am dying to try out. No idea if it will actually be useful or anything, but the inlet size is a tiny......you guessed it, 32mm. Actually i think its 32.6mm or something, but who cares
One of those stupid projects you do because you want to learn something. In my case the turbo was $50 with a rebuild kit.

Ok bringing this one back upto the top guys...
I very recently just found out the engine from my sprinter is a 2a, not a 4a.. which is really werid. It seemed to go pretty hard to all things considered...
What i'm wondering is as above, how could you 'easily' destroke these things?
Also what exactly is invovled in the 4a-ge head swap onto them?
presumably you can use a stock 4a-g cam belt as the height of the block is still the same?
