RA40 1GGTE or 1JZ-GTE with r154 box

[blanky]

here it is

I currently have my RA40 celica with an 18RG engine .The cost of a turbo setup with EFI will cost more and not generate as much power reliably. So the question i ask is do i do the easy option with the 1ggte with the w58 which is well documented but hard to find or the 1JZ-GTE which so far i have only found 1 person that has done this and not much info on it but heaps of sellers . i'm aware of the other mods required such as brakes .

PROs to 1G

1, easy to fit well documented
2, cheaper purchase price (so far that i've found)
3, lighter smaller
4, W6/7/8 box handles the power and easy fit

CONs

1, Old and hard to find a good one ( so far)
2, harder to find parts for
3, Less power less aftermarket options

PROs 1J

1, power heaps of aftermarket performance parts
2, newish

CONs

1, not documented
2, Unknown gearbox will fit well
3, possible prop shaft mods required
4, unknown engine bay mods required
5, extra weight over the axle = poor handling


Please advise or information would be appreciated

1GGTE I reckon, I've heard the 1JZ turns your car into a lead tipped dart, The 1UZ V8 is actually lighter, get one of them ;P hehe

i've also been told that in discussions online about how heavy it is. A jap V8 would be cool i would have to do some looking into it

Hi,

True that doing the EFI/turbo mods to an 18R-G is not cheap, but if well done it can pull as much power as a 1GGTE and do it reliably. If you go the bore/stroke option, which adds more cost, then a 2.4litre turbo 18R-G will be more powerful. This would be a wonderful set-up and keep the balance about the same as original and all fit perfectly under the hood, including air con (assuming you want to have air), but the costs mean you either have a lot of cash or you are a die-hard 18R-G enthusiast.

A well built turbo 1JZ or 2JZ will put out more power than a non turbo 1UZ, but not sure about the rules in Qld for engine upgrades. In NSW the rules are based upon vehicle weight, which means, for a 1100kg vehicle, the max NA engine size is around 3.4litres or so.... and 2.5litres for a turbo engine. Of course, maybe the rules have changed since I last saw them.

If you are going for max power and reliability then the costs really start to escalate, no matter what engine you choose. To do it properly you should be getting whatever engine you choose and have it fully and totally rebuilt. Otherwise you are taking a gamble and are hoping the engine you picked up is in good condition, or you'll be rebuilding it sooner than you think, and maybe more than once.

There are many options... 18R-G turbo, 1GG-TE, 1JZ, 2JZ, 1UZ, 3RZ, and even some of the V6 engines (from Camrys). And there are no doubt numerous non-Toyota engines that can be put in. Basically, given enough time and cash there probably isn't an engine that you can't fit if you discount cost and legality.

The dollars really start to pile up when you need to upgrade the gearbox (and again, should get the box rebuilt before using it if you are thinking of pulling a shite load of power), brake upgrades, diff upgrade (again, rebuilt before being used) and suspension mods so the car can handle well with the extra power and (possible) weight distribution differences (depending on the engine you choose).

Then more money to get all the above, including the engine, fitted into the vehicle. Cross member changes, engine mounting, gearbox moutings, tail shaft mods, CAI, etc. And don't forget the fuel pumps need to be added if your vehicle currently doesn't run EFI.

Realise, however, that the more power you get out of an engine, the more tempremental it can become. Many people here on these forums have powerful vehicles which are great on the track, but are a pig to drive on the streets. A powerful street-bitch becomes very very tiring after a while and you'd end up wishing you had a little less power and more driveability.

i realise what your saying River. I rebuilt the 18RG before doing my research now realising that turbos and EFI are to expensive to do and not value for money and very hard to get parts for aftermarket wise. I have a budget of around 7000 for building the Celica doing all the work myself . the 1UZ option i looked at and decided no only because of the necessity to modify the steering. I like the simplicity of the 1GGTE install which makes things cheaper when it comes to engineering but the parts are getting hardier to find. the 1J would be my ultimate choice but i think it is out of reach of my budget and i'm not 100% on understanding how difficult the engine is installed .

[JadeEstevez]

Well I'd be patient, keep on the lookout for a 1GGTE and go with that option, as you said it's easier to install and less money spent means a happier 'you' =D Besides you wouldn't have to change the drive shaft I don't think, because it uses a W5x box... Diff I think would need upgrade though, poor little T series open wheeler can't handle turbo's...
Brakes are an easy conversion, Theres a thread on here about it: Here

Theres also a rear disc brake conversion for RA40's but I can't find it at the moment =/

Hi,

Plenty of options about for EFI/turbo on an 18R-G. You can get all the performance parts, as that's what me and Witzl have done for our engines. Heaps of turbo options and a few ECUs you can buy. Also fuel pumps are about. These are all off the shelf stuff, but they cost and then you need to get them all fitted. The issue with doing an 18R-G turbo set up is the cost, and not lack of parts - but sill cheaper than quad TB.

Initially I was going for quad throttle bodies for a tough NA EFI build, but it was more expensive than going down the turbo route, so I decided to go turbo as it worked out cheaper and create more power. I do miss that sweet induction noise, but fortunately I have another car with NA 18R-G so I get my fill of induction noise anyway.

Agreed, the 1G-GTE package is all there and certainly less hassle and cheaper.

As mentioned above, be patient and check the classifieds here (and on other sites etc) and you'll find a 1GGTE package... and there's one for sale now in these forums (Timbosaurus) including all the gear you need. Also the 1J's come up for sale from time to time.

As River said^^^

1GGTE For Sale =)


Or buy This if it isn't sold ;P

[blanky]

Ok i think 'm sold on the 1ggte idea, I've been told by a mate you can buy parts through Toyota still for the possible rebuild. From there on i'm sure there are engine buliders that can get pistons, intake manifolds and fuel rails and the like.

[JadeEstevez]

Keep us posted, Start a build thread! =P

There was an RA60 in SA with a 1GGTE manual setup going for $600 last time I checked on eBay.

Could make things easier for your conversion if its still on there

Edit:

http://www.ebay.com.au/itm/270993588...84.m1423.l2649

Auction ended, but could be still possible to ring the seller and see if its still avaliable?

I have a RA40 with a NA 1G-GE,W58 and it is an easy conversion to do.58 bolts in like factory.Mid sump with minor hammer mods to the rear of sump to clear steering arms.18R eng mounts.Ford Telstar radiator.
Cheers Brett.

With your budget, go 1ggte for sure.
Wait until you find a good engine package, hopefully with the mods already done, and you are laughing.

[blanky]

what engine mods should i be looking for Witzl . i'm thinking of buying from a engine importer or half cut if it comes to that . What are the recommended mods to do to the 1ggte , I've heard of fuel upgrades due to some of the cylinders leaning out and the single turbo conversion any more info.

[masterofsinanju]

The easiest and cheapest without opening the engine is to go bigger dump pipes. Several people who've done the 1GGTE into classic celicas reckon it's worth around 30kW. If I ever get mine running I'll offer a more factual review. Single turbo is well documented. If you look around long wnough you'll find old HKS gear including cranks to build the mythical "2G", yahho.jp is the place to look.

The NA 1G-GE shares a lot of parts but none particularly performance oriented if you want to go all out.

Maybe think about some more modern (but less common conversion so far) engines?
