link inbuilt MAP sensor

[d1 mule]

heya

does anyone know what pressurethe inbuilt MAP sensor on a G1 V5 is good for??

i have a feeling its 14.7 psi but wanna be sure before i buy a new wasteate spring

cheers

More that that.


will be possbly about 18psi, but i think that was the really early ones.

but more likely to be 254kpa whatever that works out to be,
noting that 100kpa is zero, so 154 kpa, or around 21 to 22 psi.

22 psi

oh wow fast reply, cheers guys

ok then i no its a vague question what sort of boost are standard 365cc 4agze injectors good for??

Not 22 psi.

Will fall short well before then unless you run massive rail pressure.

[d1 mule]

lol yeah i wouldnt run 22 psi anyways, would they be right for 14PSI??

im a turbo noob and only wanna do stuff once not buy a spring and find out its too much for the injectors

[loose_unit]

Would also depend on how big the turbo was as well. I had upped rail pressure on my 370's on my 5e to get to 163kw.

I had my old cars fuel checked on the dyno with stock 365s and a big .70 twin entry T3/4 and it was getting lean around 12 psi. it made something like 126kwatw on that boost...but was running stock map ecu/pump still though.

I had to go with a g3 link to get full potential out of that turbo in the end.

This is my old 8:1 4agze, Link G1, T28, standard injectors and pressure.
The limiting factor was the injectors.

13.7psi

[d1 mule]

^!!!! i want at least 150 RWKW as had 75 with the old NA setup


the turbo is a HT18/T3 and ita on a ae92 CAS big port GZE 8:1 i think

Hope youve got a spare 10 grand.

Paulio

[d1 mule]

lol ten grand for what?? i dont want a 1JZ conversion man...........

the car already has a link G1 V5 with a N/A 4age tune on it, i have the motor, manifolds, turbo, wastegate, G box, diff suspension, oil lines intercooler, oil cooler etc, i fail to see what i could spend 10k on over and above what iv already spent to get to my power aim man.

on a side note, it is 22psi, and according to NZEFI the standard injectors are good for approx 13 psi, approx 150 RWKW, so ill be looking for some 440cc VR4 infectors

cheers

[Paulio]

Sorry man, dont know your history. Pretty good, youre 3/4 of the way there.

Has the motor been setup for this setup?

Paulio

[d1 mule]

yeah just need IC piping, G box X member, exhaust d shaft made and the tune i think.

i brought the motor a few months ago as a import with 89000kms on it in standard FWD trim, and its since been converted to RWD everything but iv not had it running as of yet

[Paulio]

Cool man, looks so good

What internals does it have? Do you have a project page?

my mate ran the exact same turbo on his Levin with S/P 4agze, it had really good response and was heaps of fun to drive. He was running 14psi with 365s for ages, dont think he had the fuel checked but he had no problems.

He later went with the G3 and loaded my tune onto his ecu. Ran my hoosiers and ran consistant mid 13s.

good luck mate youre beast is looking good!

[l1ttle_d3vil]

just go for some rx7 550cc injectors, i got a set for about $150 off TM. get the ones with round plugs, file the locators off the side and they'll fit straight onto the 4agze plugs. im making 168kw atw on 12psi and still heaps of grunt left in the injectors...

[thegreatestben]

Have the above mentioned 550's in my 7agte, will see how they like 20 psi when I take it back for a proper tune

[d1 mule]

the tuner at NZEFI said the G1 links dont really control "big" injectors very well and advised on 440s so ill just see what i can find around that size i think

I made 380hp atw on my 550's with increased rail pressure on my 7agte.
