Toyota Motor in an Opel?

[Skyline GTR]

what toyota engines have bee put into opel gts?

i haven't been able to contact roger wilson, so i don't know if I can get a motor from him. a friend of mine found a wreaked toyota corolla AE86 with a 4AGE motor, which would be perfect for an opel. its an I4, and its 1.6l, so why haven't i seen any gts with a 4AG?

Probably the reason why you haven't seen that type of swap is because most people who swap engines will usually go for a higher displacement one and not less. The 4AG is a great engine and can take a lot of abuse though like opel engines they need some help in order to get some power out of them, opel engines just require a lot more help.

true, but toyota 4AG motors are more common, and there is a huge aftermarket performance part following for that engine, whereas an opel engine is not as mainstream, so its harder to work with i guess. plus, the 4AG has fuel injection, depending on what year the motor is of course, but an opel motor doesnt have fuel injection, and you have to use something like the megasquirt brainbox or whatever

There were quite a few engine swap sources, with donors ranging from Toyota (I have seen several Celica 22R swaps) to Pontiac (as in the cast Iron Duke OHC 4) to Ford (several OHC 2.3's, at least a couple of them Turbos from Thunderbirds) to Chevy (I-4's not as common as the ubiquitous 60 degree V6 2.8/3.1/3.4) to Mitsubishi (several attempts, none reported as being completed) to Mazda (a number of RX7 rotaries, and I believe at least one Miata). As Jordan points out, not many folks want to go to all the trouble of an engine swap unless the performance gain is substantial. And to spend several thousand $ to do a swap, then another couple grand to hot up the new engine, is more than most folks are willing to do for a car seldom valued very highly for even the original engine, let alone the incremental cost of which none, zero, zilch will be added to the value of the end result.

The last statement is not true, opels imported to the united states in 1975 were fuel injected and then other models in europe were also efi that used jetronic L, Jetronic LE, and motronic ECUs. I, along with some other people at this time are doing megasquirt projects with stock manifolds. Once you get to the point where you have a fully programmable FI and ignition system the options are limitless for bored and stroked motors along with bigger valves, headwork, and forced induction. I feel that with the initial cost of some hop up items the opel cih engine is more than capable of putting out the power for virtually any use of the car. And it still keep the cool factor of having the original low tech engine putting out some sick power.

I like the statements that Keith and Jordan made in the previous posts. I've surely got a penny or two in my Willit? GT, and a bunch of time. Depending on which spec sheet you look at, I've doubled my HP at the rear wheels with a stock engine, almost doubled the engine size and added a fifth gear, along with a posi traction. I'm sure you can get more than my 140.3 HP at the rear wheels, but the torque curve of 175 ft. lbs., would be hard to duplicate with a CIH engine. Seat of the pants, it really does outperform what I had to start with. There have been times when I was torn with beefing up what I had or doing what I did. But after a long and anxious period of reading and thinking, I opted to go with the SFI, 3.4L/T-5 tranny. After getting all the bugs worked out, I'm glad I did. Yeah, it cost a bunch in time and money, but the WOW factor just can't be beat.

OGTS and eBay.de are both alternate sources of CIH engines.

I think the Biggest reason is like Jordan said its displacement

the 4 AGE at first glance looks to be just to small of a motor

there are 20V, 5AG, 7AG, and 8AG hybrids, there is also the GZ (GZ means supercharger) versions

the second reason is any engine swap is a big big big job
when you hear someone say just slap so-n-so engine in the thing just laugh

takes a lot of back bone to tackle a engine swap and even more back bone/skill to finish the job
