The difference of psi on
4G61 - 36.3psi MD124648 (Turbo or NT ??? )
4G63 1g
Turbo (Manual) - 36.3 psi MD124647

Did you know the part number of FPR of a 4G61 NT and how mutch psi is it.

I ask because i have a 4g61 NT and i want to install my laser manifold, turbo, fuel rail(450cc) on my elantra.

My fear is to run to rich on vaccum and lean on high boost

I ran as do some friends of mine, a non turbo 4g63 regulator. 49psi base I believe. I never had any problems on mine.

I've heard that it's 43psi base. I've had several friends use them with success too.

Out of interest, does anyone here own a 5 door lancer hatch (c63a) like me?

Hi there. Is anyone able to tell me the Denso part number for the 4G61t, 4G63T, and the NA 4G63. I have 2 FPR's here at the moment, one with DENSO 1381, and one with DENSO 1390 on it. Im looking for the FPR from a NA 4G63 for my car as im needing a little more fuel (im already running 450cc injectors). Will the stock fuel pump cope running 11 psi more pressure? I will re-wire the fuel pump at the same time. Out of interest, does anyone here own a 5 door lancer hatch (c63a) like me? Cheers -Jeza

Anyone able to check on their car at all? It'll only take a couple of minutes. The number is stamped on the end of the FPR. Cheers

Did you get a chance to test the NA regulator? This has been discussed before, but I don't think anyone ever did it. I've been trying to get ahold of a NA FPR to put on my car, because I have to richen the AFC a lot with the 450cc's and 1G Air sensor

No... i havent got hold of the NA FPR yet, but i should have one on its way. Frpm what i've read around the place, the NA 4G63 FPR is about 11 psi higher pressure than the 4G61T FPR. I will let you know how it goes once i've played with it. but that probably wont be for a couple of weeks yet. Do you know how well the stock fuel pump will hold up running 450cc injectors, and 11 psi higher fuel pressure? Should i get a vr4 pump if i can find one cheap? will it fit straight into my tank? Cheers

get a new pump, better safe than sorry. It is easier to tune out the extra fuel than not have it there at all.

My fear is to run to rich on vaccum and lean on high boost i was reading earlier and i quote The stock fuel pressure regulator on the EFI engines (4g15) regulates to 47.6psi/3.3 bar. Its part number is MD119038.

damn this is some good info!!! luckily, i have at my disposal: 1 4G63 n/a FPR 1 4G61T FPR 1 4G61 n/a FPR i am presently using the 4g61T regulator and was wondering why the hell my base PSI was running so much lower than when i had the 4g63 n/a on. i was actually gonana change out to aftermarket this coming weekend. i didnt kno that i can just slap back on the 4g63 n/a regulator and presto, have higher base psi readings. i always figured the turbo was a rising rate type and i'd have to stick to that!! woot!!!
