GT28 isn't laggy. Slower to spool than a small turbo, yes. But not as slow as a GT2x, I'll bet.
Yeah thats a good point i suppose...Gt28 would be awesome fun though you'd forget the Gt2x in a flash..

Do you know if the LCR and Cupra run the same pump. I'm around the 300 bhp mark should i be concerned.
I believe the LC and LCR run different fuel pumps from what I've learned, the LCR pump is rated to around 370bhp, the LC pump is only good for around 320-odd bhp. My stock in-tank pump is now 8 years old so I am changing it to the uprated APR pump for peace of mind.
Hybrid GT2X has full spool by 3500rpm.
I did not think it was the same pump in the LCR as in the IC, as i thought some people had been fitting a stock LCR (think the S3 pump is the same spec) pump in place if the stock IC as an upgrade when running K03s hybrid ect, however i may be incorect
Either way if you are at 300BHP, i would not be happy just running the stock pump as they have been showen to be a weak point when pushed hard and age takes a toll on them to.
Edit: just looking at what pj put and thought you are prob talking LC not IC, never mind some usless information for you anyway, lol.

Yeah, LC is 3-BAR and LCR is 4-BAR I think.
I see on ebay there is an Impreza P1 IHI VF28 turbo for sale just now! I've never really thought about going IHI.
Full boost on my vf34 by about 3200rpm. I thought the same DPJ. Though the LCR pump was about 5bar but I cant remember why or how I thought this.
TD series of IHI is better than vf as they are rebuildable and also can take more hammering it seems. If you knew you might want more in the future I wouldnt go IHI flange fitment, especially underslung as you are limited by space and heat becomes a bigger issue, might not be so bad on a LC but still top mount would be better. Also the GT range of turbos are better for higher power and delivery imo once you go past the 400bhp stage and produce the 330bhp+ power more reliably. I loved my IHI and was never going to change it for more power than that 300-350bhp band so it was a good option for a one off build and I still think the IHI is, but if there was a remote chance I might have wanted more than 350bhp at any time in the future I would have gone for a GT unit.
I think the pumps are rated much higher internally, all I know is the LCR one is rated alot higher than the LC one and the uprated APR pump is a modified version of the LCR pump and is good for around 400bhp at the crank.
I am seriously thinking of going GT28RS this winter I think, don't think I'd go IHI. I'll know more once I find out what power I'm making just now on the hybrid GT2X and WMI.
what you need to get to confirm these pump outputs is their delivery curve like you can get for 044's walbro's etc, as its a big fall off in delivert flow with increased pressure... so 4bar is'nt pump, its whatever you regulate it to... so if youi want more flow, size appropriate injectors and stick to 3bar fuel pressure.. the pump will pump more.. as opposed try to get more out of an undersize injector which is what adding 4bar fpr is about.

I've got the uprated APR in-tank pump now. Not sure if anything is done to them by APR or if they're just OE 225 pumps? Either way they're good for 360whp - 400 crank hp.
with the APR one, is it just a case of unbolting the original OE one and bolting in the new one?
any point with a hybrid KKK turbo?
