Cheers! Single, you aren't worried about lag, and changing A/R on a single turbo to get it all working as you want is a lot cheaper than on 2 turbos, the manifolding is easier, access is easier and pulling the engine is easier. I'd go for a Garrett on an HKS manifold and TRY an HKS wastegate, but you end up having to use a better made item, they can, from what I hear, be a bit suspect. Sometimes it's easier just to have a custom manifold made and choose exactly the turbo and wastegate direct from specialist suppliers. If it's an auto though be aware that they can be really horrible unless you change stall speed of convertor, the box and convertor are mapped / built to expect boost to start around 1500 RPM... Consider what ECU you want to run too, before you even start. Using the stock one is not an option at all, IMO. Quote Link to comment Share on other sites More sharing options...

Guest Usmann A Posted January 1, 2003 Share Posted January 1, 2003 no worries chris its a manual.....and i supose ur right but what about greddy t88h turbo? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 1, 2003 Share Posted January 1, 2003 Don't Greddy use KKK turbos? Reasonable parts and knowledge available for KKK in the UK, but getting pro advise on re sizing if you don't like the way it performs is a LOT easier with Garett, and you can usually find someone to swap Garett housings with you. Avoid IHI, spares are very hard to come by, and maps et cetera even more so. If you are going to be happy to just fit and forget the turbo sized as it comes the Greddy stuff looks good, I can even give you some discount on most kits if you e-mail me when you decide which way to go.

Chris Wilson Posted January 1, 2003 Share Posted January 1, 2003 Originally posted by usmann_a Chris hope u got the email...and i think greddy use mitsi. turbos Hmm, one of the jap turbo kit makers use KKK, thougght it was Greddy. I would have to say the Mitsubishi turbos would make me swerve away from Greddy if that is the case, if you decide to play with housings to move boost positions and levels around, or to get rid of any other snag, Mitsubishi stuff will be a nightmare or impossible to source. In the UK Garett is so much better to work with, followed by KKK. HKS us Garett turbos. Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted January 1, 2003 Share Posted January 1, 2003 Although the greddy t88h will give more all out power for anything within that price range.Whereas the hks twins cost more but which will give me more power with same setup...the twins or t88 single? As stated before lag is not in the equation..when it spools i need all out power until the redline. Cheers! Quote Link to comment Share on other sites More sharing options...

As stated before lag is not in the equation..when it spools i need all out power until the redline. Cheers! I can't say without having the air flow maps for both set ups in front of me. I can probably get them for the HKS, dunno about the Greddy. This is why i tend to buy a manifold then get a turbo to a known and suitable spec made up, but it is a PITA to do it that way compared to a kit. HKS do a single kit, too, that may be better, again, `cod it's a Garett. It really is a nightmare to find the turbo can't be rebuilt in the UK!!

Guest Usmann A Posted January 1, 2003 Share Posted January 1, 2003 Yeah the t51r turbo..yes iv seen this produce more than 1000 crank hp on a supe. Actually get me a price on this 1 as well pls. I M considering all turbos...so just let me know whenever no rush! Thanks Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 1, 2003 Share Posted January 1, 2003 Think they do a smaller one. T51 is FAR FAR FAR too big for what you need, it will have no boost worth talking about until about 5000 RPM, and engine's only really safe to say 7000 with that sort of torque through a stock crank. 2000 RPM power band in a road car is dire, trust me!

Alex Posted January 1, 2003 Share Posted January 1, 2003 KKK or IHI are Blitz units not GReddy. A T-63 - T-66 would flow enough for 600RWHP with a sufficently large A/R. A T-70 would give you a bit of breathing space and allow for a smaller A/R. A/R has a big impact on spool time. An HKS T04R is also suitable. Greddy T-78 or T-88 are too big for your application.

For what it's worth, if it were my car I would look to a single TO4 or perhaps the T-66 family. the single biggest mistake end users make when choosing turbos is buying them too big, it's the simplest way to build an engine that disappoints. If in doubt, err to the smaller turbo. Quote Link to comment Share on other sites More sharing options...
Adam W Posted January 1, 2003 Share Posted January 1, 2003 Consider this (all prices in dollars from MVP) PHR Stage 2 Turbo kit 5800 PHR Stage 2 fuel kit 2500 RPS Clutch 700 AEM mappable ECU 1429 Greddy 3-row IC with pipes 1424 I reckon around 600-650bhp wih meaningful power from 4k rpm onwards. I may have missed a few items off the list, and theres mapping and install costs, but that's about all you need. About £8000 sterling. Plenty of USA daily-driver cars running 10.x@130mph on this setup with drag radials. Quote Link to comment Share on other sites More sharing options...
MONKEYmark Posted January 1, 2003 Share Posted January 1, 2003 why do you need a turbo with out and out power? i would like to find out about options availible for an auto. check this site out for lots of turbos for sale http://www.directedengineering.com/turbochargers.php http://www.directedengineering.com/products.php look here for a guide to the sort of big power turbos make on supras http://www.to4r.com/toptenhp.html info on different turbos http://www.suprastore.com/rpssinturkit.html http://www.mvpmotorsports.com/default.asp there is a load of them to be going on with. also try power house racing. or sound performance Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 1, 2003 Share Posted January 1, 2003 Be incredibly careful buying turbo kits from the USA designed for LHD cars and expecting them to fit on a RHD car with steering column, brake servo, blah blah in the way!!!

Guest Usmann A Posted January 1, 2003 Share Posted January 1, 2003 i WAS AFRAID OF THAT...THE T88 IS 2BIG BUT IF I WANT MORE POWER IN THE FUTURE SAY 800HP...I DONT WANNA CHANGE THE TURBO. Quote Link to comment Share on other sites More sharing options...
Alex Posted January 1, 2003 Share Posted January 1, 2003 In which case just do the job once... If you want 1,000bhp then get a nice pair of 3037's from HKS and have done with it...no point going to 600hp then upping it....if you have a turbo that's too big it will be slow to spool be shit to drive and make you unhappy. You can sell the turbo and buy another one and plonk it on the same manifold. Quote Link to comment Share on other sites More sharing options...

Alex Posted January 1, 2003 Share Posted January 1, 2003 Sound Performance SP74? or 66? A T04R will handle upto 700RWHP with the right A/R - then add lots of NOS when you get bored. Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted January 1, 2003 Share Posted January 1, 2003 Drag only mate.....and then what 2 do......i know eventually itll b near the 1000hp m\ark,but i just wanna try 600 first,what if i get t88 with 70 shot nos,bought on low down to help it spool/ Quote Link to comment Share on other sites More sharing options...
Alex Posted January 1, 2003 Share Posted January 1, 2003 Yes that's possible but the T88H is still the wrong turbo. HKS T51R (SPL or KAI can't remember which) will have a better compressor/exhaust wheel design IMO. Yes you could use a NOS antilag system. A proper ECU is a must for this sort of vehicle. You'll need to give it loads of advance to get the turbo to spin, port the head fit a different intake manifold and a full JUN valve train kit. You'll want more than 6,000CC's of injector flow and a huge fuel system to keep up. It won't idle well (well not below 1,000 rpm). Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted January 1, 2003 Share Posted January 1, 2003 Well all i want i 600 atm.So which tubby will it b....it must have great topend. Quote Link to comment Share on other sites More sharing options...
Alex Posted January 1, 2003 Share Posted January 1, 2003 HKS T04R - guarenteed to fit a J-spec or UK car. The fuel system is upto you. I would go for 850cc injectors plus twin Bosch pumps, all running through 8AN stainless piping from the pump to the injector rail. Not sure what size connectors the HKS rail comes with....

Guest Usmann A Posted January 1, 2003 Share Posted January 1, 2003 found out that the t51 and t88 and t04r are vey similary priced frm taka kaira.So they must be a bit more over here....by te way they r full turbine kits....manif....filter...front pipe... So......i think the t51r is kinda nice? Quote Link to comment Share on other sites More sharing options...
