Other than that it's amazing!
The point is: it's a DE that makes more power than ZEs with about the same amount of miles on them. It is also still untuned. I tuned it the best I could, but am not good with computers, so no datalogging.. just easy tuning.
You always skew this. You have so much work done to it including MS, headwork, and a bunch of bolt ons. Obviously it's gonna make more than a stock ZE. Imagine the power a ZE would make with all the work you put into your DE.fowljesse wrote:I go off the forums for a bit, and everyone forgets my car
I have a mildly ported/ port matched G4 on a DE from a '95 Probe, with ZE intake cams, and it makes more power than the ZEs I Dyno'd with. I carefully port matched everything, and... well.. did a lot of other things
So, if you port/ match a G4, and set the VRIS points at the right places, you will make power. It seems to be the best N/A option, unless you're really good at tuning ITBs.
Pretty much, the only thing he's missing is the compression and the exhaust cams, but I'm wondering how much of a diff those cams would make anyway, if they were different._-Night-Shade-_ wrote:You always skew this.

The Probe, mx-6, and 626 guys dont seem to mind it. it increases performance over the DE IM with the ports being different shapes. You could have some one weld up the corners and reshape the IM. but if you are running DE heads I think the G4 is going to be the better choice.MrMazda92 wrote: Back on topic, I'm still debating using the G4 manifold or my Straight-neck. My only hesitation for the straight-neck is that I'm not wanting to square out the ports on my DE heads, as the D shape limits the angle and size of the intake ports.
Pretty sure stereoking15 just has a gutted IM with the VRIS tied open...fowljesse wrote:I believe the playing field was equal, in my case. I dyno'd with Mooneggs, and Stereoking15. Both of them have bolt ons, and Stereoking has a custom dyno tuned intake. They both have done about everything they could for power, including flashed ECUs which are probably tuned better than my MS guesswork, headers, etc...
I was only offering my opinion about the G4. Take it or leave it
but for the record I still had more torque than you 
It's true that they make more power with it, but it's more likely that the increased SIZE of the port is the cause, not so much the shape... I'm definitely not an expert, and this IS all second hand information I'm quoting. I'll say that right off the bat, but I do believe the information to be sound, as a great deal of it came from Michael Perry.Josh wrote:The Probe, mx-6, and 626 guys dont seem to mind it. it increases performance over the DE IM with the ports being different shapes.

I have dyno sheets from when my car was dyno'd with the setup it has now, My plan is to find a decently priced G4, reshape the ports and redyno it to see if there are really advantages.
I suppose you could argue with the same cams, CR, iTbs, exhaust and rpm DE heads, ported may be superior. I think it goes to show ZE ports are certainly not the worst limiting factor. I think 75 over without real porting is brilliant!leo323
yes my heads are stock ZE only mild clean up and shaved no porting or polishing heads last dyno was 273 someone here knows how much de or ze heads flow on a bench ...
