Read this post and thought I was on zcar.com with all the dissing of the Saturn and excuses for the Z32. Is it that hard to accept that a Saturn can beat a Nissan?

I tried it and have some feedback. The result, in gph, appears to be demand and not actual nozzle size. Since most folks are new to alky inj, I would suggest the result be shown as "Demand" or some other appropriate word or term and then also show the recommended nozzle size. My results showed 14.4gph and I happen to have a 10 and a 15 nozzle and not maxing the system out. SInce you would round up demand to the next nozzle size, I would say your calculation appears to be on the money.

Welcome beario. You are in the right forum and this being a Z-car forum, no one here will have already done that swap. MOF, I doubt the swap has ever been done before. However, there is a ton on information in this forum on the RB25 and the things the thing you need most, pictures and dimensions. I posted a link for you over on TC but you might have missed it. It is a good start and you should find a lot in this forum that should help answer some questions. http://forums.hybridz.org/showthread.php?t=109458

WOW!

Boy, that post must have had a lot of cobwebs.

I guess those RX7s are good for something after all, HUH? :D

Yup, stated that several times but I am sure many ignored it since the owner is a buddy of mine or maybe it cost too much. You want the best, this is it. The results speak for itself.

CONGRATS We knew thats what the car needed. 6.90 @ 103 = 10.83 @ 129.8 using the 1.57/1.26 formula.

Like I said, be patient grasshopper, 10s will come. What turbo config did you end up with? Seems like it shifted the torque curve up a bit. BTW, that AFR is too lean to be safe for pump gas and meth inj, IMO. Now the trick is putting that power to the ground quickly and efficiently.

Not sure what you mean by a junkyard turbo kit. Your focus seems to be on the turbo and that is the easy part. You need exhaust manifolds and a crossover pipe, a downpipe and exhaust and none of those can be got from a junkyard. If you add an I/C, you will need custom plumbing. You will also need upgraded injectors and possibly mods to your engine management or an aftermarket like megasquirt.

A debate that will continue for ages. I agree that longer tubes will have better thermal efficiency but I question 30% better. It is known that most of the heat reduction takes place in the first 6-8" of the tube. What seems to be ignored is the fact that the volume that any I/C can flow is contingent on the total area of all the tubes facing the inlet tank. A vertical I/C with 20 tubes is going to flow A LOT more than a horizantal with 10 tubes, especially if the tubes are the same size. So, the horizantal long tubes will have sligtly better thermal efficiency but more pressure drop. For both I/Cs to produce the same psi from the outlet tank, the long-tube I/C has to have more boost at the inlet tank which means a higher charge temp coming out of the turbo.

Came by the pits couple of times but you guys were always scrambling. Sat morning you guys were warming up the 44 for the warm-up laps and scrambling to change the alternator in the 45 so I just watched. Overall, a great race weekend and probably the best PLM I have attended since its inception but I do have lots of gripes with the track. Small field but all quality and competitive.

He's got several problems. What engine is he going to use to spool that up? Certainly not an L28ET. Hell of a conversation piece when you pop the hood. Just dont try racing anyone with it or be in a hurry moving away from a stoplight.

Forget all the theories and talk to someone who has actually done it. http://forums.hybridz.org/showthread.php?t=114612 454 SBC/4L80E Z-car finished the night before SEZ and turned its first wheel in anger there. With a too tight 2200 converter it ran 11.2x after about 6 passes and the car weighs 3,000lbs.

Ironically, Cavaliers are FWD.

dr Hunt, I was not ignoring your PMs. Did not get back from the track until almost midnight and when I saw your PMs, I went "HUH?" then went to try and figure out what you were talikng about. Just forgot to get back to ya. Glad to see you making progress and James will definitiely take care of you. Would love to see the grin on your face when you feel 800lb/ft of torque hauling you down the track.

You mean you guys cannot read invisible ink :D http://www.turbobuicks.com/forums/showthread.php?t=55769

Did it get deleted? I am not trying to sell anything just give folks here a heads-up on a good deal.

I thought the 7M was a derivative of the 3M from the Toyota 2000.

How about this one? http://www.imagestation.com/album/pictures.html?id=2102016612 Pics # 66-73.

Before you go off and spend more $$$, a smaller turbo will have smaller housings but is not going to solve the problem of the exh housing being so close to the firewall. The turbo needs to be moved forward.

NO! Keyword: regularly. OTOH, you have not said anything about the engine mods, tranny and torque converter. It will live if you are using an automatic, foot braking and avoiding excessive wheelspin and wheel hop. Even so, expect possible breakage if you have serious power. I think it is misleading to just say the R200 will take it or that jnjracing does it, without some explanation. As said over and again, the R200 diff is not really the issue, it is the halfshafts and stub axles. My hat is off to jnjracing for what they have accomplished with the stock IRS but they have openly admitted they break a lot of rear end parts. Not sure if that typifies what the "R200" can take. If you can live with the breakage, then OK.

After so many SEZs, it sure feels odd to be on the sidelines taking this all in because I am not quick enough to hang with you guys
