Supradude666 Posted January 11, 2004 Share Posted January 11, 2004 How difficult would it be to turbo charge my N/A supe??? is there someone in uk that can do it?? i know suprastore.com in usa do a very expensive kit for it.. wat about putting a 2JZGTE engine in the body that ive got?? wat exactly would need to be done?? any info would be greatly appreciated. as i would really love a turbo. even a single turbo would be good Link to comment Share on other sites More sharing options...
Paul R Posted January 11, 2004 Share Posted January 11, 2004 I'm no expert, but it would cost you £££££££££'s less to sell it and buy a TT. There are quite a few different bits on a TT compared to an N/A. Paul. Link to comment Share on other sites More sharing options...
dude Posted January 11, 2004 Share Posted January 11, 2004 Hate to say this dude , but its been said many many times before , sell it and buy a TT or get someone (who wears fur tops to meets) to stick a small block chevy in it and make some real noise !!!!

Chris Wilson Posted January 12, 2004 Share Posted January 12, 2004 This should be in an FAQ somewhere. Basically it's a hair brain idea unless you are building a mega turbo engine where you throw 90% of even a stock TT engine away. It's the sort of job whereby, if you have to ask, you shouldn't even think about it, and if you have to pay someone else it will cost the price of buying 2 genuine TT's Link to comment Share on other sites More sharing options...

Guest whele Posted January 14, 2004 Share Posted January 14, 2004 If you really want a TT my advice would be to the sell the N/A and buy one. If its more power you are after, there are other ways of generating a moderate amount of useable extra power without sacrificing the drivability of the N/A It really depends on what you want to do with your car, it its drag strip stuff then the N/A looses out big time and unless you have big bucks to throw at a very radical engine build forget it. However, if your talking track days on circuits then the N/A can sure hold its own against the TT especially on smaller circuits where handling mods count for much more than BHP and spool up time penalises the TT’s. Last year I was running 1’.27” laps at Donington, in a N/A (using Ohlins and slicks) against TT’s who couldn’t get inside 1’.30”. One of the TT’s was reputed to have 400rwbhp. On bigger tracks like Silverstone GP and Snetterton the N/A does loose out, but there aren’t many circuits like that left in the UK. With the N/A the addition of a decent exhaust (without cats) and some intake mods can free up about 15-20bhp but more importantly it enables nitrous to work much more effectively. Adding a 75 charge gave 278bhp at the wheels. The best bit is that used normally on the road it returns 32mpg, the running costs are low enough to still use the car for business use without loosing out, the insurance is dirt cheap even after disclosing the nitrous (£325). …… and it does all that on regular 95octane pump gas. Then again there is always the supercharger route…… Link to comment Share on other sites More sharing options...

And what do you think a TT would do with that set up!!! Seriously, PM me where you got the Ohlins from please. Link to comment Share on other sites More sharing options...
lust2luv Posted January 14, 2004 Share Posted January 14, 2004 Sorry, 32mpg?! £325 insurance?!! Are you actually running NOS on an SZ? Would be interested in hearing what sort of system it is, installation / running costs and how easily you got insured. Link to comment Share on other sites More sharing options...
1 Adam Posted January 14, 2004 Share Posted January 14, 2004 Been thinking about this for a while aswell. Just found the Boostlogic Kit (cheers Dude): This kit contains everything you need to convert your Non Turbo MKIV Supra or SC300 into a turbo charged sleeper. Here is the list of parts included. Boost Logic 321SS Tubular Manifold 1 5/8” Tubing and 1/2” Thick 321SS Flanges (Turbo’s with a 4” inlet clears the distributor. Manifold fits a turbo up to a T76) T61 Turbo w/ T4 flange HKS 40mm Wastegate 3” SS304 Polished Downpipe w/ Flex Joint 3” SS304 Polished Midpipe SS304 Polished Dump Tube 2 ½” Polished Aluminum IC piping 3” Polished Aluminum Intake Pipe Boost Logic FMIC Kit Boost Logic NA-T SS Braided Oil Feed and Return Kit w/ Aeroquip fittings 3” K&N Filter K&N Breathers Walbro GSS341 255HP Fuel Pump w/ Install Kit All necessary clamps and bolts for installation BL Price: $4499.00 Very expensive. Also no sign of a Intercooler? The Suprastore kit is $4069 including Intercooler. Still not to sure on whats the best route. Would like BHP figures for different kits.

1 Adam Posted January 14, 2004 Share Posted January 14, 2004 There's no mention of a upgraded head gasket on the boostlogic kit. Im sure you would have to do this to lower compression. Link to comment Share on other sites More sharing options...
Guest whele Posted January 14, 2004 Share Posted January 14, 2004 Thats obviously not 32mpg with gas, feck I'd be a rich man if I could do that one. The kit was a Holley 05130NOS which came with both 50 and 75 nozzles. It needs a progressive to controller to make it work effectively especially if you try using a 100jet. My insurance is through a subsidary company of Carole Nash, old git with accident free record and nil poir (for the first time in 25 years), but that is full comp and it includes business use.

From above: "Boost Logic FMIC Kit" HOWEVER, what about an ECU? I know I harp on about black box kludges, but really, you cannot seriously expect to kludge a N/A ecu to run with a turbo? What about dropping the compression ratio without killing the squish band? What's a squish band? obviously something they don't mention, but something you NEED to keep on a turbo engine, so thick head gaskets do not cut mustard... If you want a turbo, buy a TT, if you want a mega turbo, start with either, but expect to throw vast amounts of money at it Link to comment Share on other sites More sharing options...
Supradude666 Posted January 14, 2004 Author Share Posted January 14, 2004 I want big power tho, its the drag stuff im more into than circuit racing.. i want turbos and a dumpvalve hehe vroooooooooooooooooom PSSSSSSSSSSSSSH hehe oh yea and nitrous will be fitted to the Twin Turbo too.. i guess i'll have to bite the bullet and spend out on that TT.. well that all depends on the financial situation in april when insurance is up for renewal as i had a crash before christmas (my fault) ive lost my no clams NOOOOOOOOOO:( so i mite even have to sell my N/A as im only 21 insurance is wayyyy high even when i did have no claims bonus well i was 20 when i insured it but still even tho im now 21 its still gonna be high as im considered a big risk now i had an accident arggghhhh my lifes turned upside down Link to comment Share on other sites More sharing options...

If you want a turbo, buy a TT, if you want a mega turbo, start with either, but expect to throw vast amounts of money at it Yeh I do feel the same way, but I feel this really needs investigating. The suprastore kit has the ECU module to support turbocharging aswell as a uprated headgasket. You' be looking at over 350BHP. I'd be fitting this with a friend if I decide to go ahead with it so no labour charges. All in all you've got a mint, Manual 350+BHP under £11000. Doesn't sound that bad when you look at it from that angle:conf: Link to comment Share on other sites More sharing options...

Not 100% sure I know what a squish band is either! Are you referring to the flattish bits around the edges of the combustion chamber volume when the piston is at TDC, where the piston pretty much touches the combustion chamber roof?

Gordon F Posted January 14, 2004 Share Posted January 14, 2004 Originally posted by Darren Blake Not 100% sure I know what a squish band is either! Are you referring to the flattish bits around the edges of the combustion chamber volume when the piston is at TDC, where the piston pretty much touches the combustion chamber roof? I seem to remember these being called the squish area when working with 2 strokes. We used to measure it by taping a piece of solder to the top of the piston, replace the barrel and head and turn the engine over tdc. Take it apart again and then measure the thickness of the squashed solder Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 14, 2004 Share Posted January 14, 2004 Gordon: If you had bent the solder into an L shape you could have poked it down the plug `ole and tested without dismantling by holding one end touching the inside cylinder wall Darren: It's as Gordon says, and it's very important on high compression N/A engines, and on high boost bown ones, which are much the same thing, except one has a statically high compression and the other a dynamically high one. The squish pushes less well atomised mixture towards the plug, further atomising it in the process. helps stop det and pre ignition. Using a ticker head gasket to drop static compression ratio increases this important squish band volume, reducing its effectiveness. Using a piston with the correct compression dish or extruder doesn't, of course. Link to comment Share on other sites More sharing options...
