Nic Posted March 30, 2011 Share Posted March 30, 2011 The major issue with trying to fit the stock turbos, manifold and associated bits on an NA would be the distributor. If you did manage to remove the distributor and fit an electronic ignition, you'd need to modify the manifold, upgrade the fueling and have a standalone/piggyback ECU mapped to suit the higher compression. As has already been said anything is possible, but it's not as simple as just bolting the turbos on and would take a lot of time and money to do. After all that work at a guess you'd end up with around 280-300hp. Fitting a complete 2JZ-GTE would be a whole lot easier, cheaper and give you a better end result. Saying all that I'd sell the NA and buy a TT. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted March 30, 2011 Share Posted March 30, 2011 Saying all that I'd sell the NA and buy a TT. OR You could forget the turbo route altogether and just tune the NA to get the same result. Nobody has thought to do that either. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted March 30, 2011 Share Posted March 30, 2011 And by the same result I am of course referring to the gaping hole in your wallet. Quote Link to comment Share on other sites More sharing options...

pedrosixfour Posted March 30, 2011 Share Posted March 30, 2011 (edited) I have one. It was built by Toyota. It compressed my foot very nicely when I dropped it. It revs all the way to six thousand, seven hundred and fifty THREE. And if I leave it in first it'll scream and scream all day long.

dangerous brain Posted March 30, 2011 Share Posted March 30, 2011 Does the bottom end determine the compression ratio or the head? If its the head and that's coming off anyway during an NA-T conversion why not strap a TT head on or is that not a option? A TT loom along with ignition system and ecu would then do away with the dissy and tuning issues? Quote Link to comment Share on other sites More sharing options...
Nic Posted March 30, 2011 Share Posted March 30, 2011 Does the bottom end determine the compression ratio or the head? The pistons and the head. Quote Link to comment Share on other sites More sharing options...
nevins Posted March 30, 2011 Share Posted March 30, 2011 If you are going to do that you might as well fit a TT. Theres no real reason to remove the head doing a n/a-t conversion though. Quote Link to comment Share on other sites More sharing options...

How else are you going to fit the thicker head gasket you need to lower the compression ratio then? Quote Link to comment Share on other sites More sharing options...
nevins Posted March 30, 2011 Share Posted March 30, 2011 You do not need to lower it. As our car is proof of that Quote Link to comment Share on other sites More sharing options...

nevins Posted March 30, 2011 Share Posted March 30, 2011 Its only running 8psi and its running on optimax from the pump iirc Quote Link to comment Share on other sites More sharing options...
dude Posted March 30, 2011 Share Posted March 30, 2011 Its only running 8psi and its running on optimax from the pump iirc OK thats why its fine on the stock NA comp ratio, bet it has almost no lag and a small turbo, problem only would come if you tried to run a big turbo as they only work well at higher boost hence the yanks running 3bar + on the really big boys like the one I just bought.

nevins Posted March 30, 2011 Share Posted March 30, 2011 The turbo on there aint that big its a Garrett gt40.88 turbo. But then that is all that is needed, the car was never built to take part in pissing contests, it was built for one thing and that was to be used on track. At round 1 it did not do too bad considering it was up against Adrian Smiths celica running over 700bhp. We still managed to come 5th on the first outing of the car.

dangerous brain Posted March 30, 2011 Share Posted March 30, 2011 I think my point is that most that go for a road single want big horses and more than 8 psi of boost. That in general requires the thicker headgasket which is why most NA-T kits you buy has a thicker head gasket included. That is why I said in general the head comes off to do an NA-T conversion (your race car is a point in kind and as such a one off really and in no way indicative of the general NA-T process). So if you have the head off and a TT head and the rest of the gubbins is available why lift the whole lump out and change it if you can drop a TT head and turbo's on is my question.

Thats what I mean, no lag and loads of power should make an awesome track car, you could always run some octane booster or power pour and crank the boost up, what hp/torque is it??

Tbh thats not really the way to do it by fitting a larger gasket, you should in fact change the pisons for the low comp configuration.

At 8psi its running 380bhp, if we turn it to 10psi then its holding a steady 400 horses. As for torque last time it was on the rollers it was 365 at 8psi Quote Link to comment Share on other sites More sharing options...

nevins Posted March 30, 2011 Share Posted March 30, 2011 It has plenty of torque through out the range, We are in the TSS toyota sprint series. Only down fall is that we are in the class A1pro which has sat us in amongst fensport and merlin. Quote Link to comment Share on other sites More sharing options...

Yes but they don't because that costs money, alot of money and a big gasket doesn't. It is the method of choice for most kits coming out of yankland.
