🔧 BUILD Upside-down M90 GTP build thread

[Jimy Bilmo]

There's recent pictures of my rev.2 tensioner bracket

You need bigger letters on your keyboard

I need to start a new Whipple thread to keep these separate. Maybe after Thanksgiving. Am I going to have drivability problems with a 102mm tb?

 

[Turbocharged400sbc]

Moar bigger.

Whipple's throttle bodies are nearly the same size as the inlet to the blower

Ouch. Superchargers are too expensive.

 

[Turbocharged400sbc]

Well you could do like Cody and just get yourself another 90 mil

 

[GTPpower]

If I had access to a mill, I would think about it.

 

[Turbocharged400sbc]

Dude I've seen you hack holes in aluminum plate....you got this s***

 

[Turbocharged400sbc]

Or just get it running and then worry about the throttle body restriction in creasing your belt slippage on the top end.... in the future

 

[sktchy]

That just get it running and work out the bs after thing really is the way to go. At least then you can enjoy it without it torn apart and spread all over the place.

Yeah I rocked the FGT with just a single 78mm for a little while. In a way that slowed me down enough to not go kill before upgrading the fuel pump that i needed the minute I put that blower on basically

Operation: Let's see if a gen 3 is faster than a gen 5.





The track opens next Saturday. I think I have another cv boot to fix yet.

Oh and the car always seems to turn into storage for the winter.

I used to do that with mine while it sat, then I washed it and now I get mad at myself for it lol.

Hope to see you out there next weekend. I should probably get my red car over there at some point so you can blow my doors off again

Holy f*** where did you find that dinosaur of A 96/97 early production Gen. 3 with the tan powder coat?

Does it have the little metal tower with the vacuum ports for the boost bypass?

I think he has a boner.

We have a gm bnib gen 4.9 m90 on the front of the 442.

4/01 production engraved on it...

The throat is a little nicer as are a few other sandcasting mold changes

I think I pulled it off an engine years ago, but I can't remember for sure. But yes, it does have the vacuum tree.

Dat vintage patina

 

[GTPpower]

The finish is in pretty good shape too. However, it did need a coupler, so I think I will just steel the one from the gen 5 and use that snout too, so I don't have to swap the mps system.

 

[Turbocharged400sbc]

I think there might be a difference

 

[GTPpower]

There might be. I can't tell without actually trying it though.

 

[Turbocharged400sbc]

I think it's 1 or 2 that are offset but just leave them out and use a little extra anerobic sealer

 

[GTPpower]

Gen 5 snout on a gen 3 does not work.



It would probably work if I swapped the rotor packs too, but I don't want to reuse them incase they are part of my problem.

 

[calightbar]

Any updates on this? I started reading this post a while ago and am anticipating greatness. I also like the idea of the upside-down m90. I might have to try that one day.

 

[CMNTMXR57]

So, kinda a little off-topic. Cleaning out the garage, I have an M90 in there, would've come off my '99 GTP. I ain't doing anything with it, so if one of you clowns here in the area want it, come get it.
