you should think about a built motor instead

3" would be good (with headers) but as has been discussed above I think one would need to look at the intake side of things as well.

I've already got this covered with the Perrin BigMAF 3" CAI

What about the TB are you using the stock one or an oversize after market ?

Was planning to use the stock TB.

[smudge]

Only TB I've come across is the Cusco one which is 67mm rather than the 65mm stock TB

$1,500 for that thing is no bueno.

Twins would be more worth that kind of money. Poke them bad boys out of the hood. Wear it proud!

maybe one off a DBW V8?

[sam69]

Could a TB like this one be used off a LS2 motor



It has 6 pinouts like the 86 but I have no idea if they are the same re voltage etc as I cannot find a pinout diagram for the 86 .
Has anyone got the pinouts for the 86 ?

Being an old bloke I'm just throwing this out there to see if it's possible so maybe Ron or someone with more knowledge could respond.

I can easily make up a bigger Maf tube and piping to the TB etc .

JUN also does throttle bodies

Ok so, here's the deal. The TB isn't small for this car, at all. If it was restrictive beyond 300whp don't you think there would be more options other than JUN and Cusco? Others who have torn this motor apart and critiquing it, not once by FBM, MAP, Full-Race, JDL, or any of the tuners have said anything about the TB.

[sam69]

I would say if you are going turbo like most are then the factory TB is more than adequate as you are forcing the air though it not sucking as a PD supercharger does.

When you suck air the less restriction you have the better .

but only once you're up over 300Bhp

My thoughts are possible power increases across the board on power levels below 300rwhp. Doesn't the 210 spin at close to full tilt on stock boost?

and yes ECUtek allows you offset / rescale the MAF so you can fit a larger MAF tube with the stock plug in part

Wow, this ECUTEK appears to be very flexible, all while using the stock ecu.

and you can get a larger TB from Cusco and MAP performance - but I've yet to seee any gains published for these

Probably wouldn't see much of a difference from 65mm to 67mm, and you would see no difference if the sc inlet opening is 65mm with a 67 mm TB attached.

I'm not sure about compatibility between different fly by wire TB. If I had to guess, I don't see why ECUTEK wouldn't be able to sync with this TB but perhaps someone more knowledgeable can chime in. Curious to know what size TB this is and what size is the inlet the TB mates to?

I didn't realize these companies build twinscrew compressor kits. If they do, they are doing so missing the most critical element.

There's something else. We have something cooking here that looks to be quite a nice alternative.
