Hi everyone, just got myself a 93 r33 gts-t, having, really pleased with it but just got a couple of questions at the mo, before the modifying bug bites

firstly the car seems to be hesitatent between 4.5k and 5.5k rpm, i understand that there are two level of boost, it seems to be on about 0.35 bar on the dial up to these revs, and then goes up to just below 0.7, but does seem to be a bit spluttery when it hits 4500 rpm. any ideas ??

also it is stil limited to 112mph, am i right in thinking that i can simply cut one of the wires from the ecu to get past this, and dont have to but a speed delimited ???

Thanks in advance guys, more questions to come when i get into modding it more

welcome! I am not gonna be able to help much, but am sure one of the other guys can!

Rich,

Has your speedo been converted to MPH - the most common way of doing this is with an electronic converter which leaves the speedo face unchanged but makes it read in MPH instead of KPH. If you have one of these you'll either have no limiter anymore, or it will now be at 180mph instead of 180kph, so shouldn't really cause much of a problem ;-)

Not sure about the spluttering - dirty air filter maybe. Have a search through the tuning forum - you might find some more help on that one.

Good luck.

Welcome to the club Rich, best thing to do as your local is let us have a look at it when your free.

Good point Sarky,
Or if you'd rather do it yourself, it is likely to be plugs or plug gaps casing the spluttering which seems to be remarkeably common with these. Make sure the plugs are good quality and the gaps are no bigger than 0.8mm

If your still keen to remove the limiter then cut wire #53 to the ecu

Cheers for the replys lads, plugs were changed a week ago before i picked it up, so possible they are not gapped correctly, will check that out, along with the air filter,

speedo maxes out at 100mph so assume it is still the jap one, its still recording in kph anyway, was thinking about getting a set of the indigo dials as they read up to 180mph, but then assume that the speedo wont be reading correctly if i do that, would an electical convertor correct this ???, if so anyone know where i can get one ??

Sarky, would be great if you wanna take a look at it, just let us know when

Cheers
Rich

Rich, we are around most of the time, why dont you pop over to Richard Bell's in Guildford...he is there all this weekend....

rich , your car should not have passed the esva , if its still reading in kmh. however , if u dont want 2 chip it , which involves taking the dash off , pin 53 on the ecu , will remove the speed limeter .

 

[Rich Tee]

Cheers lads, have mailed protech about the delimiter, the actual speedo reads in both mph and kph, but the mph tops out at 100 on the dial. as far as i know it is still recording in kph, not sure about pin 53 as i think the delimiter would be a better solution.

Anyone offer any advice about the boost set up, it seems to come on higher boost at about 4500rpm, up till then its about 3.5 on the integral boost gauge, then it goes up to just under 7, is this right ??

Tigger, might pop over on sat, where about is Richard Bell, would be good to meet up with a few people in the know

Thanks for all the help lads

Rich

I will be at Richards in the morn as my car is over there being worked on. Am sure a few others will be there too!! if you give me a bell on 07739322273 I can give you directions...

 

[Guest]

when you get the chip , it will have 4 wires , one is 12 v supply , one is earth , the other 2 you have 2 splice into a wire on the back of the instrument pod.

[Rich Tee]

Rich

 

[Richard Bell]

Would be nice to know if anyone is coming down as I don`t want too many people turning up when I`m busy !!!!

 

[pete-flint]

Rich,had same speedo problem with mine. Got a s/h speedo from one of the boys and a delimiter from Amber performance, dash not too hard to play with (better done in the warm) and as previously stated four wires, two fixed to back of speedo and two to plumb into the speedo harnes plus one to disonnect completely, job done in 1.5 hours. Hardest part, finding somewhere to go more than 112 m.p.h..... HA.HA.

 

[Ludakri$]

what if u have 19or 20 inch wheels?

then the speed will still be a couple of mph wrong.

how do they fix that then?

 

[Richard Bell]

You drive a couple mph slower then it reads
