your thoughts on porting the standard manifold

What is your goal?
What turbo do you have?
If you're not going for huge power, and you don't need to reposition everything to fit a massive turbo, then port it.
You won't get a good aftermarket one for that price, and why fit a cheap one that will crack and cause you more problems in the long-run... and why spend the money on a good aftermarket one if you don't need it?

hi lads my turbo is a JGYBB37 - TO4B Compressor housing with 56 trim GT35 compressor wheel. , im hopeing for the 400 bhp and no more.
well there is some one on here selling a japspeed for £150.00 but i still dont think it will be as good as standard one.
any more thours be goos i was thinking of a dremel but will it do a good job?
keep you ideas coming in ,,,,,, chef

Mine is ported well. Do I feel any difference, no, does it make more power, prob's not. Its one of those "feel good" things that we do.
It might make air flow better, but your not going to feel the difference from doing it.
Also for £90 I'm want to make sure it a good job done inside, I paid less that that for a nice smooth finish in mine!

As Andy says above + the standard un-ported manifold will run 400 easily anyway..........spend £90 on getting something like the battery in the boot kit with a proper battery and the direct to battery fuel pump relay fitted. When the pump has a real 14 volts, that will put a proper smile on your face.........

i hadnt even thought of doing that with a relay!!! battery is already in the boot. i will have to get on the case this week. cheers for that

I have a walbro and sard fpr Steve, would there be any advantage to me doing that or is it more for the standard pump?

Thanks Steve, when did you get promoted ?
What are the benefits of having such a good voltage to the pump then?

I don't have my R anymore so can't check ( poss' getting another if job stable ).. The standard fuel pump should have altenator voltage on it, if you have less then there is something holding the voltage back and thus the pump will spin slower producing less than optimal fuel presure.
In an ideal world, yes of course there should be alternator 13.5 - 14 volts at the pump but the vehicles are 20 years old and riddled with bad earth points, believe me it's a very worthwhile job if you combine it with re earthing the pump ...........
I have no doubt it's a worth while job, my post was saying regardless of which fuel pump is fitted the voltage drop will effect the speed and there for the amount of fuel flow. If you have and can use a multimeter (voltmeter) you can find and rectify the voltage drop / potential difference. wheter it be an earth point, relay contacts or a length of cable.
If the entire cable from the relay to the pump is resitive then the fix is to replace the cable, the same applies to the ground wire.

I had a version of that turbo on my car before I changes it for the T3 GT3076R, I found the JGY turbo to be very laggy even on my ported standard manifold.
