Sr20det or 1jzgte

Recommended Posts

As I've been bolting on performance parts to my 7M motor I haven't thought, man I wish I could have gotten this stainless steel header from my dealership, or these larger injectors from PepBoys, this front mount intercooler from Wal-Mart. These parts would probably be too much for me to afford buying them new anyways.

 

You can find nice aftermarket tubular headers on eBay for the 1jz (single turbo conversion ones), bolt on any turbo to any engine, feed more fuel the same way you would your L28. I can't say I know much about the RB engine, but I didn't realize you could pick up say, a head gasket, water pump, timing belt, starter, sensors locally. I don't think it would be crazy to have an extra set of a few of the named parts above.

 

I agree with the way this thread is leaning about the 1jz being the better choice between the two engines. Even considering other engines that could fit a Z I think the 1jz is really up there on my list for turbo charged engines. I like how the I6 is easy to work on, fits so well in the engine bay. If you weren't stuck on an inline I would consider the GN engine as an option as well.

 

If you're into fooling people into thinking you have the stock engine put a big Nissan sticker on the 1jz. If people don't know that there shouldn't be a 4 cylinder, or a DOHC engine in your z car then they would probably fall for it. Or just maybe a TRD badge next to a NISMO badge would be interesting, and I'm sure that would have people talking. I agree there is something neat about saying, this is a Skyline engine, or this is the supra engine from the fast and the furious. But I would rather have my car be known for being one of the quickest imports at the track, and putting that extra cash you saved by not spending the money on hype on a larger intercooler, stand alone ems, dyno time, BB turbo, ceramic coating, etc.

 

As far as swapping the R154 onto the 1jz, I believe all you have to do is find a 1jz bell housing. I'm not sure if it bolts right up to the R154, but lots of MA70 supra guys do this swap. If you do a search on the web you'll find a pretty detailed list on howto. The R154 is a very strong tranny. lately http://www.7mpower.com/ is having hosting problems, but there are a number of MA70 cars on there with 7m-gte/R154 making over 500hp with no problems with drive train, man those cars are heavy, too.

 

The exhaust on the passenger side I don't see as being any problem. Either way you go the exhaust ends up in the middle of the car right after the tranny, so at that point the exhaust would be just the same bends out the back. I am putting the battery behind the passenger seat, and have moved my brake lines slightly to keep them away from the heat. I think moving the battery was a good idea anyways. Clifton didn't move his battery, and I understand it gets very hot there in AZ.

 

Really hope someone on this list does this swap, so there are less questions in some peoples minds about doing it. If I had found a 1jz for the same price as my 7M I would have done it.

It is true' date=' it can be done. BUT the cost of doing that far surpasses the cost of a 1jz. A redtop sr is about 2200 plus at least 1,000 for a turbo upgrade then injectors, fuel pump, ecu, fpr, upgraded maf, fuel rail, turbo manifold etc...

 

It's all the things necessary for that turbo upgrade, where as a 1jz can do it on the stock injectors, turbo, and ecu.[/quote']

 

I agree on this point.

 

I made 395rwhp with my SR20DET, but it was with the addition of a full fuel system, standalone EFI, big intercooler, huge turbo, etc... The internals were all stock, but there's a lot of money tied up in the other parts.

 

The 1JZ can make that power with less upgrades, but will still need similar parts. That all goes back to having another half a liter and 75 more horsepower stock. :)

The's something to say about the exhaust note of an inline six, too.

 

Hey Tony240ZT, I think you missed my point about the parts availability comment. I was only stating how much more convenient it is for the detroit V8 guys to buy performance/replacement parts for their hybrid in comparison to the hybrids w/ JDM only motors.
