gt4tosupra Posted August 10, 2009 Share Posted August 10, 2009 Has anyone read Japanese Performance mag Sep09 issue? page 28 shows a small article about an NA that has been turbo'd without swapping the engine. If this is done, how much would it cost roughly, and would engine internals survive? Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted August 10, 2009 Share Posted August 10, 2009 This is possible to do, search for NA/T conversions. The 2JZ-GE (non-turbo) is pretty much the same as the 2JZ-GTE (twin turbo) but the latter has more oilways for better lubrication and a slightly higher compression ratio. With the NA/T conversion you are looking at paying around £3-4k still but are limited to around 550 bhp I believe *wait's to be corrected!*. The reason the TT conversions are so popular is the cost around the same money but give much more options with regards to tuning at a later date.

Kirk Posted August 10, 2009 Share Posted August 10, 2009 (edited) turbo'ing an NA costs the same as single turbo'ing a TT. Only drawbacks are headgasket needs changing to lower compression in order to UP the boost and power, as the most you can boost safely is around 8psi on the stock HG and the w58 wont last long with anything over 400bhp running through it. Also engine internals are just as strong as the TTs. Edited August 10, 2009 by Kirk (see edit history) Quote Link to comment Share on other sites More sharing options...
dcarrter21 Posted August 10, 2009 Share Posted August 10, 2009 i brought and fitted a tt engine with new clutch, decat, fuel pump, rocker cover gaskets front oil seal and all the sump gaskets for under £2500 + a few beers! Quote Link to comment Share on other sites More sharing options...

I'm only looking for about 300bhp, nothing too mental, yet. . . . Quote Link to comment Share on other sites More sharing options...
Kirk Posted August 10, 2009 Share Posted August 10, 2009 300s is about what you will get on a stock HG. Bigger pump recommended, some drop in injectors also recommended as you will max out the stock 1s. There are kits at the minute that range from bout 2-4k roughly.. there is someone actualy selling an NA turbo manifold in the for sale section if you wanted to piece it together yourself. Best option is asking dusty (mvpmotorsports) or joe (powerhouseracing) Quote Link to comment Share on other sites More sharing options...

supspower Posted August 11, 2009 Share Posted August 11, 2009 To be fair you can NA-T for under less than 2k sourcing 2nd had parts. When i was looing into it i sourced brand new parts including mapping and everything needed to hit around 340bhp for £2281 all in incs installing the kit too. Bare in mind though thats "if" and i mean a big "if" you dont run into any problems. Quote Link to comment Share on other sites More sharing options...

The 2JZ-GE (non-turbo) is pretty much the same as the 2JZ-GTE (twin turbo) but the latter has more oilways for better lubrication and a slightly higher compression ratio. It has a lot LOWER compression ratio, different pistons, different cams, different induction, very different in fact. The cheapest and most reliable option is to fit a TT engine and ecu complete, IF, for some bizarre reason, the question poser can't bring himself to sell the N/A and just buy a TT. That is BY FAR the best course to take, but staggeringly, to me, one which no one seems to want to follow. Quote Link to comment Share on other sites More sharing options...

The reason i personally would rather upgrade or swap my engine instead of the whole car, is that i paid top whack for an excellent cond. car, so want to hang on to it! A TT in as good nick as my NA would cost around 8k, i'm guessing![sHOCK][/sHOCK] So the engine internals are different then? Quote Link to comment Share on other sites More sharing options...

This is the reason I had mine done. If you really have your heart set on it then do it but for gods sake buy a decent kit and get a good garage to fit and map it. If I had my time again it would be a TT transplant but only for the money side of it... you cant beat the sound of a single. Quote Link to comment Share on other sites More sharing options...
ray007 Posted August 11, 2009 Share Posted August 11, 2009 i have a single turbo kit for the na if you really waana go ahead with it. Garret T04R turbo HKs wastegate uprated injectors boostlogic na-t turbo manifold xs power down pipe and mid pipe Aeromotive Fuel pressure regulator Boost controller Greddy emanage blue with harness, boost map sensor and software Its near enough all you need, just probably need oil feed and return line and a intercooler if going over 7-8 psi for which you will need to do the head gasket but in turn would probably get more lag. theres a guy who has done the na-t on with the stock gasket and claims to be keeping up with a 400bhp skyline. i was going to do it but ended up buying a cheap na-TT, a bit lucky i guess. if you have a good mechanic, then go for it!! and good luck mate Quote Link to comment Share on other sites More sharing options...

If I had my time again it would be a TT transplant but only for the money side of it... you cant beat the sound of a single. If you have a great NA and do not want to lose it, then the TT swap is by far the most cost effective option in terms of reliability, power and cost. It'll also deliver the same level as power as and NA-T, but at a far lower cost. The problem comes when NA-T conversions want more power. It needs so much work deliver reasonably large power that it becomes incredibly expensive (since most of the NA parts will be replaced with TT ones). If you're going for more than 400bhp and want to keep the NA shell, then by a very long way the most cost effective way is to fit a TT lump, box, diff and single it. It will cost a lot of money, but in the long run will deliver considerably more power and longevity than the NA-T route which is fundamentally flawed and restricted. Believe me, I spent weeks on end pricing up all the options and the only one worth considering it the TT swap (I have an NA as well)) That said, it's more cost effective to just sell up and buy a genuine TT in the first place. It peanuts to take it to 400bhp. Quote Link to comment Share on other sites More sharing options...

I suppose you could investigate NOS, but personally I wouldn't do that, mainly due to ongoing (refill) costs of using NOS, insurance issues, and ability to lunch your engine if not done correctly. (I'm no expert on this though). If your target is 260bhp, I would just replace your NA lump with a TT one any day of the week, and leave the TT lump stock. No need to even decat it. If you buy an engine with a known history from a reputable trader on here, it may help to cut out some of the uncertainty in dropping a new lump in. If all you want is to drive a 260bhp-ish car, I wouldn't underestimate the advantages of using a stock engine running with stock parts. It's all very well using an eclectic mix of aftermarket parts and engine management systems if you like to tinker with cars, and are prepared for drawn-out troubleshooting exercises if things go wrong. All IMO. Edited August 13, 2009 by stevie_b (see edit history) Quote Link to comment Share on other sites More sharing options...
