If you could install all that and tune the car for 1300 dollars, thats pretty damn good.
I thought that wastegates springs are usually set pretty low, Are you sure you are capable of 400 running off just the wastegate spring?

 

is it okay to run single T with non ported motor??? what kind power level with proper tuning?
im thinking about getting T78 kit....

 

some kits allow you to keep the airpump for emission purposes.

 

see now Rhode Dog, that's the info i need! i thought all the single kits made you ditch the airpump... do you know of any specifically that don't?

 

It's perfectly fine. Spool will be *slightly* slower, and you won't be getting quite as much power up top.. But If I recall correctly.. ErnieT ran 10's (TENS) on a stock port motor with a KKK. I could be mistaken.

My friend runs a single on a TIRED stock motor (~55K) and made 390 @ 13.

Most of the power is in the tuning, but porting will help maximize spooling capabilities and overall power.

 

You could always (pretty easily) use a small electric corvette airpump just for emissions.. I believe Wargasm uses one.

 

thanks jd... i've seen people mention electric ones, but never figured out what the hell they were talking about.

 

I'll try to dig up some info.. Not sure how much is here on it, but if I find any I'll let you know. I'm curious too.

 

thanks alot i appreciate it

 

Both RX6 kits allow retention of the air pump, if i am wrong its just the RX6A.

the obvious two downsides with these turbos is that they are expensive, and if the turbo goes for whatever reason its not rebuildable in the US.

there a few threads about emissions and air pumps i found

 

The Apex and HKS single kits will let you keep the airpump.

Jason

 

is it all HKS and Apex kits or just specific ones?

 

nonseq twins is laggy as **** and it still runs fine. just downshift.

 

What hp are they making?

STEPHEN

 

not sure, i'll have to try and track them down again

one in particular that comes to mind was running a T04S so i woudl think a decent number

 

There is a GT35/40 in the works that lets you retain the airpump, and the GT35/40 according to estimates is good for 600 hp... @ which point I thought, 2/3 of the max power is a nice safety margin for a turbo... (400hp)

My $0.02

 

^^^ i think that solves all your problems right there, its affordable, rebuildable, retains airpump, spools fast, and makes plenty of power. What more could someone want?

 

that pretty much sums everything up for me! thanks DC, you too Rhode Dog.

 

Are those estimates at the engine or wheels, and are they for a piston engine or rotary. If its 600 on the flywheel of a piston engine then thats only around 500 flywheel for a rotary.

Well i see 400rwhp as the magic number, because it will beat a stock viper. I am a supra guy, but it has always been my goal to beat a viper. I think that might be where that number comes from. Also it is just a medium number. With supras, 400 is really low. Most people who are bosting are going around 7 or800 ponies. I think that 400 is a good daily driver number. Just enough to smoke most of the competition as you drive to and from work. One weekends you can increase the boost to smoke some more at the track.

 

Yes, but define "beating" a stock Viper. There's more to just punching it from a roll on the highway.. (Ignore that if you refer to other than straight line) 400hp is broken parts land for RX7's. Hard clutch dumps and drag tires are a great way to find the closest trailer. Autocrossing and track driving is a little different.. 400 hp sounds like a pretty good number to be a competitor, but I'd imagine that those guys show up modded too..

 

400rw isnt bad as long as your not dumping the clutch at high rpms...or wheel hopping.

If you run from a roll its fine. Especially if you get a diff brace
