?misfire?

[scud]

My car's turbo doesnt spoul up until 4,000rpm, thats just down to the way its been set up. However as it is going through the rev range it seems to feel like a quick misfire or gerk (whilst still pulling, so not losing power) but is this down to the way is it set up or could it be the triple clutch?
Cheers for help!

What are your mods mate?? Could be ignition related or fuel cut. When does it jerk??

IF ITs not fuel cut i would think it can be faulty ignition cables or spark plugs

could also be a faulty sensor, elecrical problem... mate had much the same thing in his 323GTR...... But check for th obvious things like mentioned above....

This is all the mod's that i can remeber:

Here is a brief run down.its a 1992 ep82 starlet facelift
Stroked to 1.5 by using a 5efe bottom end
Knife edged and balanced crank
H section rods and low comp pistons
High lift long duration cams
440cc low impedance injectors
4 branch inlet manifold
Hybrid turbo
Pressurised cold air feed
Decat
Lightened flywheel
Ogura triple plate clutch(500 bhp rated)
Quick shift
Front mount ic
Battery in boot etc
Custom interior
Switchable suspension

It only doesnt it in and around 5-5.5 rpm (1000) but its still pulling when it happens, thats why i was just woundering if it could be the triple clutch stepping in?
