[s13_brad1993]

If you only want 250-300bhp then a T28R and a set of 444 injectors is what you're looking for.
You'd be able to use a Stage 3 chip so no needing to go and get it mapped, you would also need a Z32 AFM.

[-ghost-]

A t28 turbo will keep things cheap.

[bikerboywill]

Garrett gtx2860r if you want to spend abit extra

[Maff_1991]

If I was you:

Gt28r for cheapness or gtx2867r for pure awesomeness and power

550cc injectors (just in case you want more powers in the future)

And a h-Dev chip or go see Jez for a custom map

What's the spec on your forged CA?

I was debating replacing the lines on mine for braided Teflon, probably your best bet unless you can get hold of standard metal lines that go underneath the car

[s13_brad1993]

well 1st thanks to you few who help answer my questions lol
so t28r sounds the better way to go then
and yer fort i would need a z32 maf
444 or 555 injectors
and after i have done these few mods for powerwise trailer it to a mappers then take for mot ?
sorry for the novice questions 1st big build lol
and yer as for fuel lines i dunno where the best place would be to get uprated fuel lines etc noone will sell me a original set off a car soooo
and
spec of my ca what you wanna know ??
the rods were off a friend dunno make
acl main rod bearings
pistons were off a friend also
uprated headgasket (thicker)
new head with new valves
debating on a oil cooler at the moment

[s13_brad1993]

and yes to start off with i want around 250-300 as for starting the car after these bits have done is that ok to do ??

With the specs you just gave me your engine is easily capable of these figures, Could even push it further towards the 350+ mark with the other turbo I suggested and run more boost if it has a thicker head gasket, would suggest arp head studs though if you ever decide to take it further

It starts to get expensive though

Sorry to hi-jack but sorta related to topic. What sort of power can the standard internals take?

[s13_brad1993]

300 I think will be fine for a while lol just wanna get in a drive it lol , how about getting it to mapping or mot ? As I will do the upgrades before it's ready to be moted ? Would it be fine to drive to mot or mapping sorry for the stupid question lol but if don't ask don't get a answer and no worrys Nattman

I'd say 300 max to be safe, my car ran 286 on standard internals engine was at 100k and was spot on, only reason it came out was because I had a forged one to go in

Dunno about "uprated" fuel lines. Most S13 being broken will have too much rot on the fuel lines to allow removal intact.

When my first S13 failed MOT on fuel line rot above back axle I just cable tied 8mm high pressure fuel hose the whole way for both.
Tank > filter
Return fuel rail > tank

If you want bigger then you need 2 short lengths of 8mm and some sort of joiner to join them to the stock 8mm tank, filter and fuel rail outlet.

cheers for that maff one other thing what about starting the engine wont cause any damage before it goes mapping

and yer for fuel lines im not sure was gunna go with high pressure pipe but not sure

[Maff_1991]

Not sure to be honest, was wondering that myself as I've built mine but haven't got it in the car to start it yet, although I have different cams which will effect timing etc

I'm sure it'll be fine as long as you don't rev the granny out of it, just let it tick over

[s13_brad1993]

Sweet ok mate cheers again for your help

Its bad for a freshly built engine to be left to idle for a long time it needs to be driven keeping the revs below 4k or chance you could glaze the cylinders i believe.

[pointz]

Also you need to run the engine in for a 1k miles before mapping tbh if you fit t28r and 444 just fit a stage 3 chip to run it in then go for mapping

yer heard about the 1k miles
iv spoke to a mate who said he will fit a nistune and set it up ? somthing i should do before the 1k ? i have no idea how to fit a chip never looked into it , or should i fit the t28r and keep standard injectors in till the 1k mark ? i havent the foggest on tuning etc like this
cheers for the help the car isnt far off being finish tbf so trying to get all the help before starting it up etc and buying things that wouldnt be needed in 1k miles lol
