FlatBlack Posted September 18, 2009 Share Posted September 18, 2009 Your sentence structure is appalling. IIRC the T3 maxes out around 11 or 12 psi, I doubt the T28 would get to 15. Quote Link to comment Share on other sites More sharing options...

chris51608 Posted September 18, 2009 Author Share Posted September 18, 2009 the motor that i bought didn't come with a turbo so i found the t28 turbo for 75 dollars ..should i go for it or be patient and keep looking? Quote Link to comment Share on other sites More sharing options...
FlatBlack Posted September 18, 2009 Share Posted September 18, 2009 Yes. Go with a T3 or better. Please use your shift key. Quote Link to comment Share on other sites More sharing options...
chris51608 Posted September 18, 2009 Author Share Posted September 18, 2009 what kind of turbos do u recommend besides the t03 turbos and from what cars.. Quote Link to comment Share on other sites More sharing options...
Pyro Posted September 18, 2009 Share Posted September 18, 2009 look around for a 280zxt turbo with wastegate and down pipe. should be able to find one for less than 150.00. This is by far the easiest way to get a turbo and wastegate for your engine a first gen 300zxt has a turbo that will work, but the wastegate will not be so easy to use. you can run 14 psi of boost with a stock t3. just need a good intercooler and keep it under 5,000 rpm. if you want to make it hard and put some other turbo on your engine then get a turbo that was also on a 2.5 to 3.0 liter engine. That is, don't put a turbo from a 2 liter on a 2.8. In 99% of the cases, the exhaust turbine will be too small Quote Link to comment Share on other sites More sharing options...
jc052685 Posted September 18, 2009 Share Posted September 18, 2009 You're going to get banned if you dont find your shift key soon! I am pretty sure the rb20 turbo is WAY too small for the L28. I used a rb25 turbo and it was too small. Quote Link to comment Share on other sites More sharing options...
e_racer1999 Posted September 18, 2009 Share Posted September 18, 2009 If you want a stock T3 I can get you one for $100 + ship... Quote Link to comment Share on other sites More sharing options...
ozconnection Posted September 19, 2009 Share Posted September 19, 2009 I am pretty sure the rb20 turbo is WAY too small for the L28. I used a rb25 turbo and it was too small. Yes, that's a small turbo for an L28. Perhaps. Have you ever experienced full boost at 2ooorpm on an L Series before? In a Zee? Quick little bastard is all I can say....... RB20 turbo engines run twin cam heads that flow as much or more than the P90 Turbo heads in stock form. And they rev higher too.....one can possibly draw the conclusion that a T28 off an RB20DET will be fine for an L28. It just depends on what you want and where you want your power at the end of the day! Cheers. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted September 19, 2009 Share Posted September 19, 2009 If you're running stock boost or slightly higher, the T28 would be fine since the later Z31 3.0 liter came with T25s. Quote Link to comment Share on other sites More sharing options...
jc052685 Posted September 19, 2009 Share Posted September 19, 2009 WRONG!!!! The RB25det turbo fell on its face after 4500rpm. It sucked! The reason the Z31 Kouki kame with a t28 not a t3 was because it ran less boost and a higher compresion ratio. This was because of complaints about the turbo lag from owners. ANY RB TURBO ON AN KL28 WILL BE A PIG!!!!! Fact is it isn't sized properly for out motors. Quote Link to comment Share on other sites More sharing options...

ANY RB TURBO ON AN KL28 WILL BE A PIG!!!!! Fact is it isn't sized properly for out motors. For a guy who runs 11's on the quarter, almost anything would feel slow and mismatched compared to that. But from a budget perspective, what has this guy got to loose? I still stand by what I said earlier, that being the creation of a lower rpm torque monster. I had built something like this years ago, changed the diff ratio a bit (to 4.3) and smoked everything off the lights. It was all over by third gear...the other guys just scratching their heads as they burn past after you've backed off and cruising the speed limit, them reving the guts outa whatever they had....what a feeling!!!!! I'm not saying that a top end monster isn't cool, but for the money, c'mon! I say, go for it mate. Cheers. Quote Link to comment Share on other sites More sharing options...

ben280zx Posted September 19, 2009 Share Posted September 19, 2009 Look up z31 conversion for l28et. You'll find something. Good luck. And yes, don't for get the "shift key" when you type. Mods and other have warn me before. Just a heads up. Quote Link to comment Share on other sites More sharing options...
jc052685 Posted September 19, 2009 Share Posted September 19, 2009 So... Guy asks about a specific turbo on a specific motor Guy with experience with that setup give his opinion on the setup. Person with out said experience chimes in a spews some crap about a budget and super quick spool. Dont worry about the fact that a holset can be had for under $300 and is good for over 400whp....... Have a good day Quote Link to comment Share on other sites More sharing options...

Rustyfriend Posted September 20, 2009 Share Posted September 20, 2009 Would it be out of line for me to agree? A warning if nothing else. Multiple requests to use the shift key and still nothing... Quote Link to comment Share on other sites More sharing options...

Have a good day I'm assuming this refers to my comments. I'm thinking that you're not someone who can discuss a topic constructively without slander or personal attack. "Spewing some crap" is not what I had in mind. I think it's called 'advice'. Remember friend, it's up to Chris to decide which way to go and not everyone on this forum has a huge budget at their disposal......therefore the 'advice' was given with these issues in mind. If you have some thoughts on the topic, then I'll respect you for your opinions, and I would appreciate the same sort of respect in return please. At the end of the day, if we keep on track, then we can all express our opinions without fear of ridicule. I hope YOU have a good day.

wigenOut-S30 Posted September 21, 2009 Share Posted September 21, 2009 If you are on a budget, then a T28 turbo is not for you. yeah you can pick up the turbo on the cheap.. 1. it will not give you the grins that you would get even with a stock T3 turbo. 2. It is T2 flanged and will NOT bolt up to the stock T3 flanged L28 exhaust manifold. So you would have to either find a adapter or have a T2 flange welded on the L28ET exhaust manifold. I ran a T3 for a few years and really liked the quick spool and its a fun turbo for autocross, But it fell on its face really quickly after 45-4700 RPMs. It is a great budget turbo though and will bring smiles to your face for sure!! chris51608:: for Fuel management on the cheap you can run Megasquirt and Spark. It is cheap and works fantastic! Or you could find a used SDS sytem or haltec system. Quote Link to comment Share on other sites More sharing options...
