Check this out, for those of you who dont want to spend 850 on a greddy.

lol, werd, and just for the record im over the TH manifold.. oh and darius, thank you a bunch for talking about getting the transmission mount boxed in.. im gunna get that done soon before the engines in so i wont have to worry about it when it breaks...

I guess RMR manifolds must not be too crappy if they're building **** like this



But I'll be using something similar to these designs. And I'm sure I'll have no flow problems. I think the greddy is overrated.

Also I dont know if anyone has seen the venom SMIM, its designed the same way for dsm`s and are very popular in the dsm world, my friend has been making 490awhp on 91 pump gas on one for quite a while. Same barell design, with the squared end, also inside it there are no velcity stacks.Ryan

First, that RMR intake is not a front facing throttle body. Its much more like the stock rb intake with twin TBs on it.

Second, DSM motors are four cyl motors, the plenum is much longer on a 6 cyl motor.

Leaning out rear cylinders is a real problem. A properly designed plenum minimizes that. Most people with one off manifolds don't have them flow tested.

I agree with you there, but I was just reffering to these designs are not all crappy, and a lot of high performance cars use them compared to casted manifolds. RMR uses velocity stacks in side, and their 2JZ manifold actually slopes towards the back 2 cyclinders. But regardless, with a proper slope and velocity stacks, these designs are very good.
