If I got a Holden M90, would I need the PCM and wiring harness of a L67?

[Need4Camaro]

Im 100% sure I can get a Holden M90. That asside...what would I need wiring wise? also what other modifcations would need to be made and what about the fuel rail?

Im asking this as a backup plan incase Im unable to purchase the powerdyne before it sells... I cant wait around for another kit to appear... plus Im honestly a bit more fond of the M90 than I am of the centrifugual units inspite of their ease of installation.

Holden M90's will bolt directly in without any fitment issues as they are because they are all RWD ... and I believe that also elimates the thermostat issue.

I don't think anyone else has gone the Holden m90 route, so we can't tell you how to modify it. An L67 PCM won't work because you'll be trying to control your rwd trans with a fwd computer. I believe another member tried hooking one up to test out and the car wouldn't get out of park.

I also highly doubt the supercharger will drop in so easily. There are more than likely a lot if little things that will need to be addressed for it to fit; thermostat housing and water lines ate completely different, IIRC. And then you have to figure out a way to make the cable driven throttle body work with your drive by wire PCM.

Seriously, you're best bet is to just wait until you can get a Powerdyne kit. Just be patient. The time you'll wait for a kit will be a lot shorter and less stressful than the down time your car will face once you have a m90 that you know nothing about and don't know how to make it work in your car.

This builder created a "Holden style" M90, but everything else would be what you would have to do.

And NO the t-stat housing is still at the rear of the car.

Please do some more research on the Holden and rethink this idea - unless you have lots of time and CASH.

So far from what I've read I'm still not quite intimidated enough... might be different if I jump into things... I contacted Holden though and they told me that the thermostat on the M90 is on the front (passenger) side on their cars - as they sit on the opposite side... Maybe they're lying, who knows, but even still a custom thermostat housing won't be too bad... I kind of have an idea for that which will still keep the thermostat on the front of the car.

The only thing that slightly intimidates me about this swap is the wiring and possibly tuning. SLIGHTLY worried about the L36 pistons too so Im going to run less boost and make up for it with a cam since this setup can't be intercooled... I heard Meth wasn't very good on the bearings of the M90's as well.

this makes me chuckle. you are gonna be in for a nice surprise. lol

By bolting in without fitment issues, I mean you don't have to butcher either the intake or the firewall for it to fit... there will be modifications involved yes...but nothing like cutting a FWD M90.

Edit: After doing a bit more research, yes you were right FirebirdGT - It is on the back of the S/C - That alone though...still isn't quite enough to scare me out of it though.. I'm not sure why... I mean I understand it makes less power than a Powerdyne and the Powerdyne is easier to install - I guess because it's a bit more rare. But Im pretty sure I'll have enough to get it to work $$$ wise. The Powerdyne - for the time and wait to attain one (provided the one on here sales before I can get my hands on it) I would rather just fab a Procharger or Vortech - I honestly might consider that too...

Re: If I got a Holden M90, would I need the PCM and wiring harness of a L67?

So far... IF the Powerdyne does sell before I can get my hands on it... here's the list...

I'm sorry, I'm not one to wait up for anything .. I mean, waiting is good don't get me wrong... It's just I have a deadline to use this money, it's complicated but when I hold money for long periods of time waiting for stuff, other people tend to find uses for it and so I'm not going to let that happen.

L67 Heads - $100
Aussie M90 - $1,700 (Elbow and Shipping to USA included)
L67 Wiring Harness - $100
Misc MATERIAL - $500
Misc LABOR - $2,000 <== Estimated max cost of labor to create PARTS for fitment
Fuel Pump & Rails - $300


Total Cost: $4,700 - Estimated Max cost to install the S/C with custom parts - I spoke with some shops about this aswell and the average labor price was ~ $2k...

Anything up to $6k won't bite me too bad... I DID want to stay cheap don't get me wrong... The Powerdyne definately does do that ... Its just Im not sure if I really will have an opportunity to wait for a kit to arrive.

For the MONEY...Realistically, Turboing admitively is a much smarter alternative, so I CAN see why this idea is seldomly pursued... The only problem with Turbo'ing my car is ... getting an intercooler to working on it (Firebirds don't have grilles). unless I used an Air to Water but I heard those weren't great for Daily Driving.

I REALLY want scott's Turbo system (UR50SL0) but he's in Indiana and needs the car to beable to fab a system and...Unfortunately I won't be able to make that drive for a long time as I'm quite wrapped up in Seattle.

might want to do more research or you will be really kicking yourself when you try and set the sc on the intake and realise the firewall is making it tough for you. ;) What you are trying to do has been attempted before, and that is why I am giving you a hard time. It is not going to fit without cutting and fabbing. We have tried it before and found it comes out too far. The elbow for the turn comes out too far and hits the firewall. Also $1700 for the m90 is outragous, you can get them cheaper than that. For the cost and power gained, procharger is going to leave you happier and produce more if you want supercharger.

This kit would save a lot of time and trouble for you. The kit is already put together for you so you dont have to go through the trouble of trying to figure out how to make the M90 work. Its also designed to produce around 500 hp rather than the 20 or so hp you'll gain from the M90.

Sorry if the link does'nt work, but its ZZ's stattama turbo kit for the L36 for $3600.

I have seen intercoolers on a TA mounted on both front corners of the car facing downward.

Although I think he'd be much happier with a turbo, the kit you posted, techsan, won't work unfortunately...

Notes:
Works with Impala, Regal, Grand Prix, Monte Carlo and can be adapted for Bonneville. Does not work on F-body.

zzp does offer a turbo kit for the fbody cars. You have to eliminate the a/c but they do offer one

I'm well aware - Meemperor is always preaching about how good it is. Not to say it isn't, but Need4Camaro wants to keep his A/C so that wouldn't work either. Custom is the way to go :poke:

Meemperor is preaching the Cartunning turbo kit for $5000 its a nice kit but the price is high,
