Hey guys

Last week I picked up my '95 GTR Vspec.

I'm damn happy with its performance, but I would really like some more bottom end. The car is completely stock. It even has the factory boost restrictor in place.

What can I do to get more bottom end. The car feels like it has no power whatsoever below 3 grand. Now im not too keen on doing too many mods because I am broke. I also dont need any more attention that im getting from cops and the like. So i'd like to keep it as stock as possible (incl stock exhaust).

Opinions and advice please

Thanks

Make sure the timing is correct.

Change any fuel filters that are old.

Check the plugs and the gaps are correct as well.

Get a compression test done by a mechanic and a dyno.

Just to check where things are at.

If its as bad as you say there may be an underlying fault somewhere.

Plus make sure the factory cat convertor isn't blocked which can cause excess back pressure and loss of torque.

An exhaust will also help bring boost on sooner which will make the bottom end more responsive. (If you have a crappy press bent factory one)

Its just undergone compliance, so all fluids have already been changed, etc etc.

It really isnt that slow, but the take off compared to other gtr's is much slower. Driving around the city at about 2000 revs isnt that much fun. Perhaps I'm being a bit pedantic.

But honestly, there is no pickup from the turbos until about 3-3500 revs. And compared to my old stock gts-t, it's much slower under 4 grand

4 grand up its a monster :P

Would a boost controller help boost pick up any quicker ?

I have one still handy

hi, with a boost controller you will be able to bring the boost on earlier, although not by a large amount.

generally speaking, there is nothing you can do if you are used to the gtst

i have had two gtsts, and am often in a stockish gtr, and i know exactly what you mean about the slowness..

by the time my gtst reaches 4 grand you are accellerating pretty quickly and about to break traction, whereas you really need to keep the revs above 4 grand in the gtr to get a similar response. its normal, just fit the electronic boost controller and get used to it :P

Full exaust/front pipes/hi flow cat first..

then Adjustable Cam gears will help bring boost on alot earlier.

and take out the boost restricter, (won't really help low rpm tho, where the exaust/cam gears will)

very true

well ive been driving it a fair bit for the last week or so.

I'm also slowly getting used to driving it, and becoming more accustomed to its driving style

Revving it out when I need more power, and around the streets up to 3k rpm is sufficient

yeah dont drive it like a wuss!! my last gtr and my current one (both 32s ) seemed a little sluggish below 3500rpm but remember they do rev to 8k! definatly do an exhaust first, 3 inch at least and tuned lengh front pipes with high flow cat, will make more power and more rb26 noise!

have you dropped it from 7k yet??? damn it feels fast when you do that!!

my gtr is stock and I removed the boost restrictor and boost went up from 12psi to 14psi and gave me an extra 22awkw (with standard exhaust) and on the road it blows away a lot of more powerful cars

Did removing the boost restrictor give you much better response down low ?

I'm having a fair bit of trouble removing this restrictor. Need to get the right set of pliers :)

Damn, the fuel economy on this thing aint too bad either. Averaging between 11-13 litres/100. Highway/city driving :D

Squeeze the restrictor out from the outside, use any sort of pliers and pop it out like a cork, should take you a couple of minutes. probably didnt help much below 3G although definately hit boost harder and pulled better through to redline.

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
