so whats up with the lexus maf mod

djalkyd · 01-30-2006, 04:14 AM

i have been reading around and seeing a lot of people talking about using 550cc injectors with the V8 lexus maf. will the stock computer run these items without triggering anything or would you have to get some sort of tuning item like a piggy back or something?

i am interested if this actually works just by getting new injectors and maf.

also, what do you all feel about these turbo manifolds and down pipes on e-bay? i am looking at upgrading my exhaust and i would also like to get a nice manifold. i know i would have to replace the stock turbo and get an external wastegate. i just dont know if i want to deal with that yet or not.

i dont want gobs of power but a little more than stock would be nice, maybe 300hp or so.

if u just want 300 hp the stock turbo will run just fine. When u get a dp make sure u either get one that has a turbo elbow built in or comes with one.

I think with basic upgrades you should be close to 300 hp without having to do all the lexus and injectors

First thing is to make sure it has a good head gasket and all routine maintanance is done

yes do all the maintance first, get it to stock level, then worry about upgrades. you dont need to really worry about the amf and or fuel unless you goto upgrade the turbo. dont get me wrong, you still may get some power, but to get the full benifets of those you want a upgraded turbo. a couple of bpus will get you some quick power: boost controller, intake, exhaust.

sweet. well i ordered new IC piping, down pipe, test pipe, turbo inlet pipe and cat back exhaust today so she should be breathing better soon. all that is left is new BOV. i was thinking of an hks super sequential.

the HG was done 3 months ago and i have the paperwork that arp was used and a non stock gasket was used. the guy i bought it from said he used a metal one.
the turbo was also rebuilt then.
the car runs like a champ for having 145000 miles on it.

so sweet for me then, i am glad to hear i can hit 300 almost stock.

thanks all
