I want to install a TRD SC in my 94 LC???

[T0nyrific]

Hey everyone!!

I am a newbie to this forum so I had a question. I asked CDan about getting a supercharger and I was told that the 93-94 LC were not intended for a SC. What did you guys use for an alternative source of fuel to keep the motor from knocking itself to death??? I want to make it most reliability as possible. I plan to DD my 94 LC with the SC. I drive roughly 20 miles a day...

Some feedback and input would be great!!!

He told me I need to find an alternative fuel system. He said he uses methanol injections..

He's right

So if I run the SC with methanol injections it will be reliable and fine? I don't plan on pushing it all the time, but do plan on DD everyday!!

Well it should be ok with a mid to low mileage cruiser ~(90k-130kmiles) in good shape.. but im no expert cdan could tell you since hes the only one I know running one with the methanol.

actually they did make a supercharger for the 93-94 but they dont make the pipe fit kit anymore. You could still buy one or get a used on for your year if you can find one or you will have to do some mod work.

Is anyone running a SC on their 93 or 94 LC and has no problems at all??

I take really good care of my LC. Its at 145k miles.

Is the mod work hard??

The bigger issue there is making your OBD1 work with having something on it that is trying to run at the full potential of the supercharger - you need to run the methanol to keep from detonating your motor all to crap.

If you are looking for more HP, & if I had a OBD1 rig - then I'd be looking into either a turbo & doing a set of low comp pistons & thicker headgasket (big $$), or stepping back & learning the ins & outs of positive manifold pressure & deciding if it's worth it - or if a Tundra motor swap / _________ motor swap was going to give you longer term reliability.

If you want to reliably run a supercharger longterm, it looks like you'll need to learn the whole system so you personally know what's right for your motor since you don't have OBD2 - or else pay the big bucks to have a guy who is in charge of your motor & keeps you from melting pistons.

If it's nothing more than a HP issue, it almost seems like a V8 swap would do you more good - a little more $$ upfront, but no worries of melted pistons down the road.

Thanks for the input!!! I might consider installing the SC with methanol injections. Seems likes the best choice!!

If the problem is that the fuel injection system cannot keep up with the added demand that the supercharger creates, then upgrading your fuel injection system would be the solution, this is pretty common practice in the supercharger world.

I had a 8-71 Weiand supercharger on my Chevy 454, and it obviously needed FAR more fuel than the stock fuel system could provide. The solution is an upgraded fuel system.

There are well developed DIY fuel injection systems out there, this is one worth looking at.

The fit kit only addressed a relocation of the PAIR valve. It did nothing to the fuel delivery, which is the real issue. TRD dropped the PAIR kit because it inferred that that was all that was needed to makke the blower operate properly on a 93-94. It's not. All it does is retain the PAIR for emissions compliance.

Fuel management MUST be addressd on a 93-94 or that dog simply won't hunt.

G'day CruiserDan, I am a newbie to this forum and have purchased a trd sc to fit to my 93 cruiser...now i join/read this forum too late it seems.

My query is around the pinging you have solved via methanol injection. I live in Australia where the 93/94 models came out without PAIR valves, EGR or cat converters as they where seen as commercial vehicles until 95.

What chance do you think I may have of avoiding the pinging issues given no EGR to increase intake temps and 98 octane fuel is readily available which assists in resisting pinging?

I understand you can not comment particularly on my vehicle but is the pinging on the 93/94 that excessive it can not be avoided without major mods?

Cheers Pooley

Welcome to mud Pooley ....

Interesting fact about your rigs emmition system I wish I can tell you something more useful but I'm still a freshmen here...

Having no EGR, Cats.. etc, sounds like it could be a bonus when it comes to your SC setup but I could be wrong, that is just the first impression I seem to get.

At least you are in the right place when it comes to figuring out things like that

The only way to know for sure would be to install it and see what happens. If it doesn't knock under boost over ~3,100 RPM then you are not going to have a problem. If it does you will need to get more fuel to it.

At one time Safari had turbo set ups and they had some sort of overlay controller that they added to the vehicle. I would imagine something like that would work. I think it was called a "Uni-chip" or some such.

Thanks guys, given its sitting in the shed, I suppose I have nothing to lose other than a weekend put aside to try it. I mainly bought it for towing capability so I will soon find out how it perfoms under load. My brother in law owns a Lamda meter, so i will use that to ensure no lean condtions occur under load too.

dan, how about the old school rising rate fuel pressure regulator like the old supercharged 5.0 mustangs used to run? Not the cleanest in regards to A/F ratios but will definitely keep the motor fueled under boost with the appropriate high output fuel pump.
