Greetings All.

Ive decided to hold ALL of my engine mods back, untill i have enough $$ to buy a 6g72 DOHC MIVEC block with manual transmission. (As a replacement to my 6g72 SOHC TF block).

In the long run, would it be possible to twin turbo this motor using GT28's or something? Possibly something smaller due to the LOW amount of torque that the MIVEC has down low?
I dont really see why it wouldnt be possible . . . :doubt:

Im not sure about the possibility of turboing the MIVEC, You would probably want to talk to Dave about that.

Yeh some people are slow about this turbo business.. I'm yet to get any information on turboing a astron 2, it has been done a few times but i wanna know price wise what it'll cost rather than a 'oh probably about x-amount' and stuff, slackasses.

You sure can turbo a mivec. Its shouldn't be any different ... I did read an article on turboing an FTO (2.0 V6) some time back ... so it can be done

Shouldn't too different from turboin a VTEC Honda, & how many millions of them are there in the States?
Tuning during the Cam change would be the biggest issue I'd imagine, but nothin a decent ECU wouldn't handle.

it wouldn't be worth the hassle turbocharging a mivec motor,cause of the high compression they run. cost to much money to set it up

I think I'd agree with this. The exhaust valve cam makes it cool to optimise control over tuning but realistically, it's probably something that will see most gains from NA tuning as opposed to boosting. That's what it was developed for, more power and torque from an NA engine while returning good emissions, economy and drivability at the same time.

But couldnt I lower the compression using a decompression plate to lower compression to 8.0 or 9.0? Then using the turbos to get the compression back up high and using the variable valve technolgy to retain driveablity? Also, as far as i can see, i wouldent require new cam shafts, just a very nice ECU and an engine rebuild with stronger conrods (aluminium anyone?) and maybe strengthened pistons?

Thoughts Peoples?

It's not impossible.. I've seen a Turbo FTO with the 2L V6 MIVEC engine.. and according to the guy it was a hell of a job, but definetely worth it.. He showed that by gunning it, when he left the import yard!

Lower Compression - The 6G72 in the TFs are fine, compression wise, to turbo as they run low enough compression for low boost. But the MIVEC runs higher compression and it would end up costing you more, for pretty much similar results! All in all.. Personally.. I think its a waste of time waiting and spending all the money on a MIVEC when you could get similar results from a NON-MIVEC!

Correct me If i'm wrong people.. That last part was an opinion!

dished pistons or combustion chamber grinding will sort that easy enough

good on ya! it ain't as simple as that. the mivec is made to be a high comp,N/A, performance engine. you would be way better off turboing a non-mivec motor. a lot of hassles for nothing TONBA

what about supercharging a MIVEC

Greetings All.

Thanks for all the replys all!

Super charging is the same idea as turbo charging. Both give boost, just using different methods of doing so.

Hmmmm, Booya? Mitsiman? Thoughts?

The compression is what I was thinking about in my first post, I just wasnt sure if I was confusing myself with the GDI, but I think they're both high compression motors anyway, so I should've just said it lol.

Turboing a MIVEC would ofcourse be more hassle due to the higher compression, but would allow for a greater scope in tunning, and not to mention provide a wider power curve as you can play around with the cams and change over point :D

no u wouldn't.

i said dishing or grinding would sort the high compression side of things. from there on in its almost identical to using a 3L from a magna... the same deal applys. ur going to need a AMC so the tuning is not a worry with either of the engines as its done from scratch
