Hi there. I have a r33 gts t s2 whith rb25det from 1996. I bought a top feed injectors rail front facing plenum and 90mm throtle body. The injectors are make jecs and thei are orange color is like to be rated at 850cc. I want to know how do i calculate the latency maths to ad them to my pfc d-jetro.

My mods are

Pfc d-jetro late model with commander

Top feed injectors

Large fuel rail

Front facing plenum with 90mm throtle body

Tomei poncams

Big valves

Big ar70 topmounted turbo

Forged engine internals

Light fly wheel and clutch heavy duty

3"exhaust from turbo backwards.

My car has a unstable idle too much fuel not burn coming out from the exhaust, hi rpm on idle like 1500 to 2000 rpm.

I need to take the car to tuner but it canot drive with crap idle.

Thanks for reading my post. Sorry about my wrighting iam portugese.

Here is a bit dificult to find a tuner that can tune an apexi pfc d-jetro. There are many that are specialized in AEM or HALTECK. But i will folow your advice and try to find one. Cause the car idles very bad and the fuel mixture is way far to rich. Thanks mate for the advice

      Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.

      What brakes on R34 GTT(Europe)

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
