Can I put a 20g on a standard engine ...
Ok so just looking for a few more responses from my thread yesterday... I would really love a sc38 for my 99 type r but cost wise unless somthing second hand comes up I doubt I will be getting one, as for 1k I could get a decent 20g and a decent set of front brakes..
So it realistic that I can fit a 20g to standard 99 engine or would it be more realistic to go 18g, I would be happy now with 370 /380 bhp.
Many thanks

Td05 18g would do the job then fella plus some 550 injectors and a few othe bits and bobs standard rods are the weak point plus you need to add on the cost of getting the car mapped

To run a 20g on a classic without incurring problems, you could do with:
550 or 740 injectors,
Ported headers,
a Harvey up-pipe.
And a remap...this last is vital, unless you want the engine to go pop.
Just bolting one on will make more power but it will be laggy and will max out standard injectors, maybe running lean enough to det itself to death

I already have fitted a set of Harvey ported headers and up pipe, my main issue is I don't want the engine to pop..
I'm looking for around 370 bhp so what would be best, a 18 or 20g with 550 or 740 injectors..
And yes I only had the car mapped last year but will be going in again once the work has been carried out

I've got 740's on mine, but it's a forged 2.5.
Your mapper might be best to advise which injectors and turbo.
If you want to go to 400 then a 20g will be called for, but be advised that at that power level on mine, Harvey said I could use tubular headers too, which I have.

But a decent brand adjustable FPR is a good idea simply because it's brand new and prob got a superior quality membrane. And of course, you have the option of upping the fuel pressure a little, to help with 'underperforming' injectors...
You won't go wrong with the Fuelab jobbie.

possibly a bit late now but my RA made 395 with an SC38 and 555cc Nismos, standard headers and uppipe and a bitsa turbo back system.
Now running harvey headers and uppipe, harvey built 18g and the same 555cc injectors, I dont have a print out but i'd say its easy 370-380 if not more. 1Bar at 3100 and full boost (1.45) at 3300.

I've been offered some 740 Inj so may just grab them while I can, I have a feeling its not what I want more what comes up on the market I was originally thinking 550 Inj with a 18g now I'm thinking 740inj with a 20g...
But I guess I will have to see what comes up

So a bigger turbo needs less boost to run the same power as a smaller turbo I.e. TD05 16g to a 20g? Feel free to correct me if any of this is wrong guys, so is it a case of you can go bigger and run more power just don't exceed 1.6bar ???
