haha sorry about the huge pics, but as for wiring, mine didnt come with the plug for the other side, so i found one and had to repin the center wire, but you can see in the is pic how they match up, on mine its:

Q45 tps Sr harnessred - blue/red stripewhite - whiteblack - black



as for the flange, i just bought a piece of 4"x4"x1" block of aluminum for 7$ at supermarket metals, drilled and tapped 4 holes, plasma cut the center out close to the edge and then cleaned it up with cone shaped grinding stones

hahaha spanish, it is real, garret part #714568, i just didnt feel i needed to pay $1400+ on the same turbo with a few meaningless holes drilled in it and and garrett cast into the side $900 shipped i couldnt pass it up, only a .63 t3 single scroll but i kinda wanna see what she can do compared to all these other combos that are comin out now for the 35r, when i bought this there werent too many choices to choose from

finally took it out yesterday and got a lil footage, didnt finish my dash wiring yet, also found 2 descent size boost leaks when i got back to the shop, i have a 14-15psi spring in my 44m gate but its still creepinp a lil, hits almost 19psi by redline(7800)

I know, I was just giving you a hard time.

That's an excellent price for that turbo. A couple hundred dollars cheaper than even my Garrett dealer price.

We'll i have a small update but sorry to say i have no more pictures till i get my manifold done, and my turbo and ems shows up! I did wire the Q45 tps though, along with wiring in the MSD style injector plugs, and i will be running the harness/throttle cable under the manifold, Also i just ordered some russel braided line and fitting for my catch can set-up, along with 3 qts of Redline MT-90 transmission fluid. I will also be ordering my AEM wideband, and Tial BOV by the end of the week, i will post a huge update once everything shows up!!

so i was reading your thread. i would love to have the money for all of this, but one thing i didnt see is what youre doing so the rear-end will hold 500+rwhp.

might i suggest, and i hope i dont get chastised, but Ford has a 9inch rear end. its solid axle and would handle all the torque you could ever deliver from the sr20.

good luck with the rest of your build.-mike

Mike,

The 240sx rear end will have no problem holding 500whp. It's usually the transmission that goes first.

If the trans doesn't go, the axles will go...

R230 like the tt z32 diff is the mack daddy rear end swap for 240 anyways, but like spanish said the r200 is fine

since the q45 throttle body is a big topic among these top mount threads i was just messing around in the garage and mounted a s14ka auto throttle body up to my s14sr greddy 1pc intake manifold, the ka throttle body is a direct bolt on with no adapter flange but what would it take to wire this tps to my s14sr?

the outside dimension and external physical size of the throttle bodies are similar, i think the s14sr throttle body is 50mm and the ka is considerably larger, i searched but couldnt find any info on the ka throttle body swap or wiring to a sr20, any ideas so i dont have to weld a flange and overkill with a q45tb but dont have the smallest sr throttle body ever made

I honestly can't think of a single 240sx with 500whp that had problems breaking the stock axles over and over again?

I do recall this one fellow broke his stock axle three times in the exact same place...but then he swapped out his SPEC stage 5 clutch for something with easier engagement and never had the problem again.

Let me rephrase that... If you plan on dragging the car at all and are running sticky tires, dumping the clutch is going to break something... Hell running a 2-step and launching the car under boost is going to twist the stock axles out from underneath the car(with sticky tires). It may not happen the first time or the tenth time, but it is going to happen. Either that happens or the trans blows apart... I think Kentuckyslider? destroyed his 2nd gear in his trans with just 370rwhp and sticky tires. Now rolling on to the power or driving on the highway or street, then no, I don't see it happening. But when/if you drag the car, and you hook, something is going to give regaurdless...

Yes, i no stuff will brake, but whats the fun if it doesn't=).. I have a backup KA transmission, and a extra set of stock axles, i will be happy if the trans just holds up for the summer so next winter i can do the z32 transmission swap, im not near as worried about the rear as i am the transmission i no the sr transmission has a week 2nd gear with sticky tires..

same here z32 transmission will be coming whne mine goes

i did some research on the a/r difference with .84 and 1.06 and the 1.06 on the t4 actually spools about 500 rpms fast this was on a b16c1 with 9.1: 1 compression. so i will be doing the same one as you. cant wait to get back from fishing. it will be "Christmas in hollywood, with Ben back up in the hood" of the nissan lol

the s13 throttle body is 60mm, the s14sr is 50mm i believe, i have to figure out how to wire the ka s14 throttle body tps to a s14sr harness since it is bigger and bolts perfectly.

Considered trying to track down an S14 SR20DE throttle body? It's 60mm and bolts right on.

I have one... No you can't have it... It's actually 65mm at the opening and tapers down to 60mm at the TB plate.

I was going to but when i ordered i wasn't really planning on going with the dual gate set-up so it was alittle more expensive then i though, but when i talked to them they said if i ever wanted to i could send it back anytime to get the coating done, so i just figured when i have the car in the garage this winter i will get it done..

yeah that makes sense. i wonder how much it could help spool up. is your head port and polished. all i am trying to figure out is things to increase spool up and get better air flow. your doing solid lifters? waht cam rotation will you use.

you probably have this posted all ready and i probably read it all ready. but justa quick refresher would be nice

Sweet baby Jesus, -12 lines for the catch can? How many ports are you using from the valve cover to the catch can?
