Nissan Primera P11 Petrol Turbo Conversion?

Brendan wrote: heh, Bolting on a turbo isn't hard. The Hardest part would be drilling a hole in your block for an oil line. (not hard)The most expensive part of doing a 'bolt on' would be getting the custom exhaust done. And maybe the intercooler if you don't do it yourself.

What about the dyno time to tune after fitting, that and some means of remapping the ECU.

Personally i think bolt on is cheap...

In NZ$ This is the approx cost for me to do it.

Turbo + manifold $300-$400
Injectors $70-100
Piggyback ecu $200
Intercooler+piping $200-$700(depends if you do yourself or pay someone)
Exhaust (from scratch) $700 - $800

So $1470 to $2200 for a bolt on. Add a bit more if you want like better clutch new fluids etc. Thats if you get the parts from NZ of course. I know parts are a bit more in the UK but so would the whole sr20det motor ;).

A Good Low km/mile Bluebird/avenir det would cost $900 to 1300 and GTIR would be 1500 to 2000 but don't forget you would still need the exhaust + Intercooler and the piggy back ecu would help

$1 NZ = 0.38 uk Pounds

Bolt on vrs STANDARD sr20det the bolt on will win. Due to the compression. If you rebuilt the det with forged internals, bigger turbo etc you can do the exactly the samething to the bolt on setup. Your N/A bolt on WON'T BLOW UP if it is set up correctly. Same as a DET, if its setup wrong you will have problems.

My 2 cents

A lot of what you just said you need or would do with a sr20det motor anyways... (are we talking about cost, det vrs bolt on??)

Normally the manifold/turbo/dump pipe is one piece.
Or if it isn't i don't see why the dump pipe would be separated from the turbo..


You don't HAVE to have a metal gasket UNLESS your going for high power... if you were then you would of had the head off anyways. I have seen 300+HP builds on a bolt on sr20de+t with factory DE internals/gasket

You dont have to have a metal headgasket.

Far, 350 pounds for a tune?

You could always get those JWT ecus from the US.

Or Just use a Bluebird or avenir ECU, just have to match injectors and air MAF
OR buy a consult cable and tune it yourself ^^


Yeah I have read that.

Those prices are VERY high compared to how much you can import them for. 80 pounds for a factory gtir manifold? This is quite pricey
Downpipe? these are normally still attached to the turbo? (unless my down pipe and your down pipe are different things?)

As i said before, I see it cheap as these parts are easily obtained for me. I could easily get a GTIR Manifold for about 10 pound for example.

I have Built both a Bolt on T4 and a "Drop in" T4 (my current one) and Building a in-between ve+t type set up.

Edited my post :)

Yeah i read that JWT.

Plenty of cars here have been tune without a dyno/"rolling road" We have a 450hp+ turbo t4 in the club that was tuned by simply driving it, but saying that tuner was an expert.

I think this is a debate more than an argument. I enjoy this type discussions :P
