gordy.r Posted January 27, 2009 Share Posted January 27, 2009 Ok just a thought... If I were to buy a N/A, run it for 1 - 2 years and uprate pretty much everything with the view to go for a fully uprated engine (forged internals etc) and single turbo in the 3rd year.... can a 3.1 / 3.2 stroker kit be applied to my N/A engine before hand?? (this would also mean using the same N/A engine for the conversion) Just a thought Quote Link to comment Share on other sites More sharing options...
steady_dave Posted January 27, 2009 Share Posted January 27, 2009 I'm a bit of a noob when it comes to Supra's and would also liek to know if this were possible. I suppose if you go NA-T at the same time then it would simply be a way (albeit an expensive one) af getting rid of the lag created and improve low end torque. Whether this is possible I have no idea, but would be an interesting thing to find out! Quote Link to comment Share on other sites More sharing options...

gordy.r Posted January 27, 2009 Author Share Posted January 27, 2009 (edited) better off fitting a built TT engine with single or with current prices just buying a fully set up single in the first place and save a lot of time and money Yeah I know this would be cheaper, but i'm getting rid of my Skyline for something a little cheaper to run for the next year or so due to lots of motorway mileage, hence the reason going for a N/A first. Plus I would know the history of the car and have the time to sort out the brakes, suspension, exterior / interior, and the IC etc etc before the conversion. It was just something I was mulling over in my head. Why is it better to go for a TT engine rather than converting a N/A? Is there that much of a difference between them?

benkei Posted January 27, 2009 Share Posted January 27, 2009 My mechnical kowledge is limited, but I'd say that if you wanted to stroke the n/a to say 3.2, then uprating it with a future turbo in mind would be a solid base for it. As you're spending on maintaining and building the engine, then adding a turbo at a later date would compliment the build. I'm not sure on what needs to be done in an na-t conversion (I'm sure someone on here could tell you for sure), but if the internals are strong enough to handle the boost from a single ,then you shouldn't have too much trouble? Would make for an interesting build thread too! Quote Link to comment Share on other sites More sharing options...

NA blocks dont have oil squirters on the bottom of the pistons for a start, much better to start with a TT lump if you are going for power.

Is it possible/practical to put these in? Or is it just better to swap the block from a TT to the built n/a? Quote Link to comment Share on other sites More sharing options...

Plus I would know the history of the car and have the time to sort out the brakes, suspension, exterior / interior, and the IC etc etc before the conversion. Getting a 6 speed NA would be a good start, leaves your options open......... 1) selling - resale of an NA with the 6 speed should be better 2) can 'just' swap the engine at a later date as the 6 speed is man enough for TT or single 3) If a NA-T setup became available (from a crashed car - not that cost effective any other way really) you could again swap it in with no gearbox worries.

(this would also mean using the same N/A engine for the conversion) Just a thought Stroker kits are only used on 2JZ's with a HUGE turbo to help reduce the lag and lack of low down torque (although its going to be a pretty small difference). The cost to build a stroker engine is massive, so unless you are going to go for a 800+bhp drag car it's an utterly pointless route to take. As has been mentioned, the NA engine is not a starting point for a stroker as it doesn't have the oil squirters along with many other things. It is far, far more cost effective to just buy a GTE engine and drop it in. With bpu mods you'd be at power levels almost double an NA stroker, but for far less cost.

As I said, I will be going N/A to begin with for the sheer cost of my next 2 years motoring, I'd love to keep the GTR but it is just not practical just now and has cost me sooooooooooooooooo much to rebuild and then replace the engine (3 engines, 6 turbos and a lot of tears in 2 years haha! - long story) I hate asking the noob questions but i'm guessing when the time comes to swap I can pick up an already uprated TT / Single engine from a reputable dealer / performance engine outlet.... Otherwise i'll just be 'buying bits' for the next 2 years until I find the right engine for the job haha - the missus is gonna love me, just got rid of all my old Skyline and MR2 Turbo odds and sods haha!

Homer Posted January 27, 2009 Share Posted January 27, 2009 It's always best to ask before spending the cash so good that you ask now before going down a pointless and expensive route. I have an NA now and have spent months looking into the options available (and I mean every possible option), the only viable one is to just drop in a stock GTE enginen and modding from there. There is nothing even close to it in terms of cost vs performance and future modification. Quote Link to comment Share on other sites More sharing options...

I have looked at getting a 6 speed N/A, is it the same 6 speed box that is in the manual TT? Quote Link to comment Share on other sites More sharing options...
