turbo

Does any body know if the c27a is the same size as the 2L turbo. Is the 2.7 physicly the same size just bored to 2.7L. I am looking to do a turbo conversion and i was wondering if i got a 2 litre turbo and took the intake and manifolds off it and put them on a 2.7 that i will be building, would it work? Rather than having to get all the manifolds custom made.

Probably not without custom stand alone ECU...

It has been said (though to my knowledge never confirmed) that the winged turbo ran off of the ECU too...therefore its not just a bolt on type thing....

If you really want to turbo the 2.7l why go through all the headache not knowing if it will work but as said it probaly wont work without a standalone ECU. standalone custom ECU could cost up to 3000+ so if your really into making it a turbo then check this link for a pre-made version:

with money and devotion anything is possible with the legend.

I have no problem running a stand alone engine manigement system, I will of course look into running a piggy back computer with my original computer and hopefully get that retuned as well. I have looked at the pre made turbo kit but am not convinced it is wat i am looking for it is designed to run on a realitivly stock motor with a very small intercooler plus i am in Aus so not an option. I have decided against trying to use parts from the C20AT as i have purchased a 2.7 turbo motor form America that i am getting shiped here to Australia (not that i am not still skeptical about it) but just a standard C27A over here is worht well over 1k to buy. I am going to rebuild the motor with forged pistons, rods and maybe get it ballanced and run a front mount intercooler. So it will be a long project and this is why i didnt want to buy a bolt on kit.

I see, sounds interesting. as for piggyback devices been there done that, I dont recommend it at all its a WASTE of money. If you want to spend $300+ on a piggyback rather do a port and polish job which WILL make a difference. Anyways let me know how the turbo mainfold goes when you do the project, good luck.

yeh I will get my head ported but not polished I have talked to a local engine builder who gave me a quote. The piggy back computer didnt work with your car but with a turbo the ammount of tuning to air fuel ratios is a lot more so i am thinking it may be of help. that is of course if i can get the motor running on my comp. I see a lot of headaches coming my way. fitting a front mount intercooler wont be an easy job either. unless anybody can help. but i still gotta wait a month or two for the motor to arive.

I thought we came to the conclusion Honda didn't make one of these?

Na it wasnt the 1100 1 from ebay that guy was dodgy as and you guys turned me off that 1, i found another 1 on ebay and the sellar had 100% feedback. was only 600 so i decided to take the risk now i just gotta hope it pays off. Honda didnt make this motor but in my opinion sombody in japan has been mass producing them some time since. I may be very wrong but i have come across to many pictures all with the same turbo manifolds and intake to think they just aren't around. also the 1 i purchased is a jdm motor. So even if it turnes up and the seller was dodgy i should at least have a motor to work on turboing.

you can probaly remove the AC components and in the front of the radiator you can put the intercooler.

I may have to do that i will look into doing it with the ac still in but if i have to i will. i will talk to an engineering shop to see if they can maybe cut new holes with out weakening the structure or if they have any other ideas. im open to any sugestion. just here in the summer it sucks without the ac

The AC cannot operate without its components, you cannot put in the intercooler without taking out the AC components. But you can always go with a small intercooler, thats why the turbo kit for the legend was made that way because there doesnt seem to be any other way. Problem is if you run the AC without its components the car will heat up very bad, not good.

Going smaller wont help its not the actual intercooler that will be the problem. I will get a different front bar (probably get a custom fibreglass 1) and mount it in front of the ac radiator, it is getting a pipe to each side of the intercooler that will be the problem. there isnt really any room on either side of the radiator to get it through that i can see??

This was the link. it wasnt listed as turbo i was just browsing and i came accross this and was looking at the manifolds so i asked if it was turbo and the guy replied yes they have both turbo and non turbo. so il have to wait and see if not il just have to work on a custom job.
